How Are RMDs Taxed? (w/Examples) + FAQs

Required minimum distributions face taxation as ordinary income at your current marginal tax rate the year you take them. The Internal Revenue Code Section 408(a)(9) mandates these withdrawals from tax-deferred retirement accounts to prevent indefinite tax deferral, pushing many retirees into higher tax brackets and creating unexpected consequences for Medicare premiums, Social Security taxation, and overall retirement income planning. According to IRS data, the penalty for missed RMDs dropped from 50% to 25% under SECURE 2.0, yet correcting errors within two years reduces it further to 10%.

Understanding RMD Taxation Fundamentals

Required minimum distributions receive ordinary income tax treatment, meaning the amount you withdraw adds directly to your taxable income for that year. The government designed tax-deferred accounts like traditional IRAs and 401(k)s to encourage retirement savings by allowing pre-tax contributions that grow without annual taxation.

This arrangement creates a tax bomb in retirement. The IRS eventually demands its share through RMDs. When you reach age 73 if born between 1951 and 1959, or age 75 if born in 1960 or later, the SECURE 2.0 Act requires annual withdrawals from most retirement accounts.

The taxation mechanism works simply. If your RMD equals $30,000 and you fall in the 22% federal tax bracket, you owe $6,600 in federal taxes on that distribution. State income taxes add another layer depending on where you live.

Your marginal tax rate determines the actual tax cost. Unlike capital gains taxation with preferential rates, RMDs face the same rates as your wages, bonuses, or business income. The 2026 federal income tax brackets range from 10% to 37%, making tax planning crucial as RMDs push many retirees across bracket thresholds.

Which Retirement Accounts Trigger RMD Taxation

Traditional IRAs subject you to RMD taxation starting at your required beginning date. This includes rollover IRAs containing money from previous employer plans. SEP IRAs and SIMPLE IRAs follow identical rules because they function as traditional IRA variants for tax purposes.

The 401(k) accounts from your employer also mandate RMDs and taxation at the same age thresholds. This applies to 403(b) plans for nonprofit workers and 457(b) governmental plans. Each account type calculates its RMD separately, and the aggregation rules determine whether you can combine withdrawals.

Inherited IRAs create different taxation scenarios. Non-spouse beneficiaries typically face the 10-year distribution rule requiring complete account depletion within 10 years of the original owner’s death. If the original owner had already started RMDs, beneficiaries must take annual RMDs during years 1 through 9 and empty the account by year 10. These distributions face ordinary income taxation in the beneficiary’s hands.

Roth IRAs escape RMD requirements entirely during your lifetime. The SECURE 2.0 Act eliminated RMDs for Roth 401(k) and Roth 403(b) accounts effective January 1, 2024, aligning them with Roth IRA treatment. This represents a major shift because previously, employer-sponsored Roth accounts required RMDs despite containing after-tax money.

The Tax Calculation Process

Your RMD amount comes from dividing your account balance on December 31 of the previous year by your life expectancy factor from the IRS Uniform Lifetime Table. This creates the minimum withdrawal amount that triggers taxation.

For tax purposes, the entire RMD counts as ordinary income unless you made non-deductible contributions to your IRA. Non-deductible contributions create basis in your IRA, meaning a portion of each distribution returns your after-tax contributions tax-free. You must file Form 8606 to calculate and report the taxable versus non-taxable portions.

The timing of your first RMD matters significantly. You can delay your initial RMD until April 1 of the year following the year you turn 73. However, this forces you to take two RMDs in one calendar year because your second RMD still comes due by December 31 of that same year.

Taking two RMDs in one year doubles the taxable income from these distributions. This bunching effect can push you into higher tax brackets, trigger IRMAA surcharges on Medicare premiums, and increase taxation on your Social Security benefits. Most financial advisors recommend taking your first RMD by December 31 of your 73rd year to avoid this problem.

Federal Tax Withholding Options

Federal law requires automatic 10% withholding from IRA distributions unless you specifically opt out. You can increase withholding up to 100% of your distribution or eliminate it entirely by providing instructions to your IRA custodian.

The withholding choice creates strategic opportunities. Unlike quarterly estimated tax payments that must reach the IRS by specific deadlines, withholding from retirement distributions counts as paid evenly throughout the year regardless of when the actual distribution occurs. This IRS rule allows you to take your RMD in December, withhold enough to cover your entire year’s tax liability, and avoid underpayment penalties without making quarterly estimated payments.

Consider this example: You owe $15,000 in total federal taxes for 2026. Your RMD equals $60,000. You take the entire RMD on December 15, 2026, and request 25% withholding, which equals $15,000. The IRS treats this withholding as if you paid it evenly across all four quarters, eliminating the need for quarterly estimated payments and letting your money stay invested longer.

This strategy works particularly well for retirees with irregular income or those who forget to make quarterly payments. However, it requires sufficient RMD amounts to cover your total tax liability through withholding alone.

Account-Specific RMD Tax Rules and Nuances

Different retirement account types apply unique rules for calculating, aggregating, and taxing required minimum distributions. Understanding these distinctions prevents costly mistakes and opens planning opportunities.

Traditional IRA RMD Taxation

Traditional IRAs allow the most flexibility for satisfying RMD obligations. You must calculate the RMD for each traditional IRA you own separately based on each account’s December 31 balance. However, you can aggregate the total and withdraw the combined amount from one IRA or split it among multiple accounts as you prefer.

This aggregation rule creates planning flexibility. If you own three traditional IRAs with $10,000, $15,000, and $20,000 RMDs respectively, you can take the entire $45,000 from your most liquid IRA while leaving the others untouched. This helps if one IRA holds illiquid assets like real estate or private placements.

The taxation occurs regardless of which account provides the distribution. If you take $45,000 from one IRA to satisfy all three RMDs, that $45,000 counts as ordinary income subject to your marginal tax rate.

A critical rule change effective 2025 affects rollovers in RMD years. Previously, if you withdrew $50,000 from an IRA with a $10,000 RMD, you could roll over $40,000 to another retirement account because only the $10,000 RMD was ineligible for rollover. Under new IRS guidance, the entire combined RMD for all your IRAs is now ineligible for rollover. If you have three IRAs with $10,000 RMDs each and withdraw $50,000 from one, you can roll over only $20,000 because the $30,000 total RMD obligation blocks that amount from rollover treatment.

SEP IRAs and SIMPLE IRAs aggregate with traditional IRAs for RMD purposes. You calculate each account’s RMD separately but can combine them with your traditional IRA RMDs and take the total from any combination of these account types.

401(k) and Employer Plan RMD Taxation

Employer-sponsored plans like 401(k)s, 403(b)s, and governmental 457(b)s operate under stricter rules. You must calculate the RMD for each employer plan separately, and you must take each RMD from its specific account. No aggregation exists between different employer plans or between employer plans and IRAs.

If you have two 401(k) accounts from different employers, each requires its own RMD calculation and withdrawal. You cannot satisfy one 401(k)’s RMD by taking extra from another 401(k) or from your IRA.

The taxation functions identically to IRA RMDs with ordinary income treatment. However, employer plans have a unique exception for active workers. The still-working exception allows you to delay RMDs from your current employer’s plan if you continue working past age 73, provided you own less than 5% of the company.

This exception applies only to the specific employer plan where you currently work. You must still take RMDs from IRAs and previous employers’ plans. Many retirees working part-time capitalize on this by maintaining minimal employment to defer their current employer’s 401(k) RMDs while drawing other retirement accounts first for tax planning purposes.

One planning strategy involves rolling old 401(k)s from previous employers into your current employer’s plan before reaching RMD age. This consolidation lets you delay RMDs on those rolled-over amounts under the still-working exception, assuming your current employer’s plan accepts rollovers.

When you finally retire, your first RMD from the employer plan comes due by April 1 of the year following your retirement year. The same two-RMD bunching issue applies if you delay this first distribution.

The 403(b) plans offer one unique advantage. Unlike 401(k)s, multiple 403(b) accounts from different employers can aggregate their RMDs. You calculate each separately but can take the total from any of your 403(b) accounts.

Inherited IRA and Beneficiary RMD Taxation

Inherited retirement accounts create complex taxation depending on your relationship to the deceased owner and when they died. The SECURE Act of 2019 fundamentally changed these rules for deaths after December 31, 2019.

Spousal beneficiaries enjoy the most flexibility. A surviving spouse can treat an inherited IRA as their own by retitling it or rolling it to their own IRA. This eliminates immediate RMD obligations until the surviving spouse reaches their own RMD age. Alternatively, spouses can keep the account as an inherited IRA and calculate RMDs based on their own life expectancy or the deceased spouse’s remaining life expectancy.

Non-spouse beneficiaries face the 10-year rule for accounts inherited after 2019. This requires complete distribution of the inherited account by December 31 of the 10th year following the owner’s death. The taxation treatment depends on whether the original owner had already started taking RMDs.

If the original owner died before their required beginning date, non-spouse beneficiaries can skip annual RMDs during years 1 through 9 and take the entire balance in year 10. This flexibility allows tax planning to minimize the impact by withdrawing more in lower-income years and less in high-income years.

If the original owner died on or after their required beginning date, beneficiaries must take annual RMDs during years 1 through 9 based on the beneficiary’s life expectancy, plus fully deplete the account by year 10. Missing these annual RMDs triggers the 25% penalty even though the 10-year deadline hasn’t arrived.

The IRS issued relief for 2021 through 2024, waiving penalties for missed annual RMDs during those years. However, beginning in 2025, beneficiaries must take annual RMDs or face penalties if the original owner had started taking RMDs before death.

All inherited IRA distributions face ordinary income taxation at the beneficiary’s marginal rate. This creates significant tax burdens for beneficiaries in their peak earning years who inherit large IRAs. A 45-year-old inheriting a $500,000 IRA must distribute the entire amount over 10 years, potentially adding $50,000 or more to their taxable income annually when they already earn substantial employment income.

Inherited Roth IRAs follow similar 10-year distribution rules but maintain their tax-free status. Beneficiaries pay no income taxes on distributions from inherited Roth IRAs regardless of when the original owner died, provided the account met the five-year aging requirement.

Roth Account RMD Treatment

Roth IRAs eliminate RMD requirements entirely during your lifetime. You can leave the money growing tax-free indefinitely because you already paid taxes on the contributions. This distinction creates powerful estate planning opportunities because you can pass larger account balances to heirs.

The SECURE 2.0 Act made Roth 401(k) and Roth 403(b) accounts function like Roth IRAs starting January 1, 2024. Previously, these employer-sponsored Roth accounts required RMDs at the same age as traditional accounts despite containing after-tax money. The new law eliminated these RMDs, removing the need to roll Roth 401(k)s to Roth IRAs before age 73 just to avoid RMDs.

This change simplifies planning significantly. Retirees can keep Roth money in their employer plans without forced distributions, maintaining creditor protections that employer plans offer in many states.

However, one quirk remains for 2024. Any RMD that was required for 2023 from a Roth 401(k) but payable in 2024 due to the April 1 delayed deadline must still be taken. This affects individuals who turned 73 in 2023 and delayed their first RMD to early 2024.

Beneficiaries who inherit Roth accounts still face distribution requirements under the 10-year rule, but all distributions remain tax-free. This creates the most tax-efficient inheritance compared to traditional retirement accounts.

Federal and State RMD Taxation Details

The layered taxation of required minimum distributions extends beyond simple federal income taxes. State taxation rules vary dramatically, and RMDs create ripple effects on other aspects of your tax situation that many retirees overlook until filing their returns.

Federal Tax Bracket Impact

RMDs add directly to your adjusted gross income before any deductions. This means the distributions stack on top of Social Security benefits, pension income, interest, dividends, and capital gains. The combined total determines your marginal tax bracket for the year.

Consider a married couple filing jointly with $60,000 in Social Security benefits and $30,000 in pension income. Their taxable income before RMDs might place them in the 12% bracket. If their RMDs add $45,000, their marginal rate could jump to 22% on the last dollars of RMD income. The effective result means their RMDs face taxation at both 12% and 22% rates depending on how much income fills each bracket.

The bracket jumps create disproportionate tax costs. The 2026 federal brackets for married couples filing jointly include breaks at $23,850, $96,950, $206,700, $394,600, and $501,050. Crossing any threshold means the income above that level faces the next higher rate.

This stacking effect makes tax planning crucial before RMDs begin. Strategies like Roth conversions in the years between retirement and your RMD age can shift traditional IRA balances to Roth accounts, reducing future RMDs and keeping you in lower brackets during your 70s and 80s.

State Income Tax on RMDs

State taxation of retirement income varies dramatically by location. Nine states impose no income tax at all: Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming. New Hampshire taxes only interest and dividends, exempting retirement distributions.

Four additional states exempt all retirement income from taxation while maintaining income taxes on other sources. Illinois charges a 4.95% flat income tax but exempts retirement distributions entirely. Iowa, Mississippi, and Pennsylvania also provide complete retirement income exemptions.

Michigan recently expanded its exemption significantly. Beginning January 2026, qualifying pension and retirement income becomes fully exempt from Michigan income tax for residents meeting age requirements. This includes IRA and 401(k) distributions.

Most other states tax RMDs as ordinary income using their regular state tax rates. California’s top rate reaches 13.3% for high earners. New York, New Jersey, Oregon, Minnesota, and other high-tax states impose substantial burdens on retirement distributions.

Some states offer partial exemptions or deductions for retirement income. Alabama exempts private pensions but taxes IRA and 401(k) distributions, though residents over 65 get a $6,000 exemption. Colorado provides a retirement income deduction up to $20,000 for those 55 and older.

The state tax impact extends beyond current residence. If you earned pension benefits while working in one state but retired to another, the source state may claim taxing rights on those pension payments. RMDs from IRAs and 401(k)s generally face taxation only in your current residence state.

Social Security Taxation Interaction

Your RMDs can trigger or increase federal taxation on Social Security benefits through the combined income formula. The IRS adds your adjusted gross income, tax-exempt interest, and one-half of your Social Security benefits to calculate combined income. If this total exceeds $25,000 for single filers or $32,000 for married couples, up to 85% of your Social Security benefits become taxable.

RMDs push many retirees over these thresholds. A single person receiving $24,000 in Social Security benefits with $15,000 in other income before RMDs stays below the taxation threshold. Adding a $30,000 RMD creates combined income of $57,000, making up to 85% of the Social Security benefits taxable.

The calculation becomes complex because the thresholds don’t adjust for inflation. More retirees face Social Security taxation each year as RMDs grow with account balances. The effective marginal rate can reach 40.7% in certain income ranges because every additional RMD dollar makes more Social Security taxable while also facing its own taxation.

This interaction makes QCDs particularly valuable. Qualified charitable distributions excluded from income reduce the combined income calculation, potentially keeping Social Security benefits tax-free or reducing the taxable portion.

Medicare IRMAA Surcharges

RMDs affect Medicare premiums through Income-Related Monthly Adjustment Amounts. If your modified adjusted gross income exceeds certain thresholds, you pay surcharges on top of standard Medicare Part B and Part D premiums.

The IRMAA calculation uses tax return information from two years prior. Your 2024 income determines your 2026 Medicare premiums. For 2026, IRMAA applies when your 2024 modified adjusted gross income exceeded $109,000 for single filers or $218,000 for married couples filing jointly.

The surcharges escalate through five income tiers. A single filer with $109,001 to $137,000 in 2024 income pays an additional $81.20 monthly for Part B in 2026, raising their total premium to $284.10. Higher income levels face progressively larger surcharges, reaching $487 monthly at the top tier.

RMDs can push you into higher IRMAA tiers unexpectedly. Consider a married couple with $200,000 in annual income from pensions and Social Security. They stay under the $218,000 threshold until RMDs begin. A $25,000 RMD pushes them to $225,000, triggering $81.20 monthly Part B surcharges for each spouse, or $1,948 annually in additional Medicare costs.

These surcharges apply to both Part B and Part D premiums separately. A couple just over the first IRMAA threshold pays approximately $2,300 extra annually combined for both spouses and both premium types.

Planning opportunities exist because IRMAA uses modified AGI from two years earlier. Taking larger distributions in the year before Medicare eligibility at age 65 creates no IRMAA impact for your first two years of coverage. Similarly, QCDs reduce modified AGI and can keep you below IRMAA thresholds.

RMD Penalty Structure and Compliance

The penalty system for missed or insufficient required minimum distributions imposes severe financial consequences designed to ensure compliance. Understanding the exact mechanics and available relief provisions prevents costly mistakes.

The 25% Excise Tax Mechanism

The Internal Revenue Code Section 4974 imposes a 25% excise tax on the amount you fail to withdraw from your retirement accounts. This tax applies separately from any income taxes you owe on the distribution itself.

The calculation uses the shortfall amount, not your total RMD. If your RMD equals $40,000 but you only withdraw $25,000, the penalty applies to the $15,000 shortfall. The excise tax equals $3,750 in this scenario.

This penalty structure differs fundamentally from late payment penalties on income taxes. The 25% rate applies to the full shortfall regardless of your tax bracket. A person in the 12% federal bracket faces the same 25% penalty rate as someone in the 37% bracket.

The SECURE 2.0 Act reduced the penalty from 50% effective January 1, 2023. Previously, that $15,000 shortfall would have generated a $7,500 penalty. The new 25% rate still imposes substantial costs but cuts the damage in half.

The penalty applies annually if you fail to take RMDs in multiple years. Each calendar year’s missed RMD creates a separate 25% penalty. Forgetting RMDs for three consecutive years means three separate penalty calculations and three separate Form 5329 filings to address the problem.

The excise tax comes due with your income tax return for the year of the shortfall. You must file Form 5329 to calculate and report the penalty. However, reasonable cause provisions allow penalty relief if you correct the mistake promptly.

The 10% Reduced Penalty Window

SECURE 2.0 created a corrective distribution window offering penalty reduction to 10% if you fix missed RMDs within two years and demonstrate reasonable cause. This provision dramatically lowers the cost of compliance for those who catch mistakes relatively quickly.

The two-year correction period runs from the year you should have taken the RMD. If you missed your 2024 RMD, taking a corrective distribution by December 31, 2026, qualifies for the reduced 10% penalty instead of 25%.

Using the previous example with a $15,000 shortfall, correcting within two years drops the penalty from $3,750 to $1,500. This $2,250 savings makes prompt action valuable when you discover missed RMDs.

The “reasonable cause” requirement remains somewhat ambiguous because the IRS hasn’t defined it precisely for this new provision. Generally, reasonable cause exists when you can show you tried to comply but circumstances beyond your control prevented proper withdrawals. Illness, mental incapacity, reliance on erroneous advice from financial institutions, or administrative errors typically qualify.

The reduced penalty offers particularly important relief for inherited IRA beneficiaries navigating the complex new rules. Many beneficiaries missed annual RMDs during 2021 through 2024 because of confusion about whether annual distributions were required under the 10-year rule. The IRS provided blanket relief for those years, but beneficiaries must take annual RMDs starting in 2025 if the original owner had reached their RMD age.

Form 5329 Filing Requirements

Form 5329 serves as the official document for calculating and reporting the excise tax on missed RMDs. The form has multiple parts addressing different retirement account penalties, with Part IX specifically covering RMD shortfalls.

You must complete a separate Form 5329 for each year you missed an RMD. If you discover you failed to take RMDs for 2022, 2023, and 2024, you file three separate forms even though you might submit them together with your current year’s tax return.

The form requires specific information:

Line 52 identifies the RMD amount you should have withdrawn. This comes from calculating your account balance on December 31 of the prior year divided by your IRS life expectancy factor.

Line 53 shows the amount you actually withdrew. This might be zero if you took no distribution, or a partial amount if you withdrew something but fell short of the requirement.

Line 54 calculates the penalty. If you’re requesting a penalty waiver for reasonable cause, you write “RC” to the left of this line followed by the shortfall amount, then enter zero on the line itself.

Line 55 requests the actual payment. When seeking a waiver, you enter zero and attach a penalty waiver letter explaining your situation.

The critical filing strategy involves requesting penalty waivers even when you believe you might owe the penalty. The IRS has historically granted waivers in most cases where taxpayers corrected the shortfall promptly and provided reasonable explanations. If the IRS denies your waiver request, they send a notice demanding payment, but filing with a waiver request costs nothing and often succeeds.

Penalty Waiver Letter Components

A persuasive penalty waiver letter attached to Form 5329 includes several key elements that maximize approval chances. The letter should demonstrate you corrected the mistake, explain the reasonable cause for the error, and show steps taken to prevent future occurrences.

The opening paragraph states your request clearly: “I am requesting a waiver of the excise tax penalty for my missed required minimum distribution for tax year 2024.”

The explanation section describes exactly what happened. Strong examples include: “I relied on incorrect information from my IRA custodian who told me I didn’t need to take an RMD until age 75,” or “I suffered a stroke in November 2024 that left me hospitalized and unable to manage financial affairs,” or “My financial advisor miscalculated my RMD and withdrew an insufficient amount.”

The correction paragraph demonstrates prompt action: “Upon discovering this error on March 15, 2025, I immediately withdrew the $15,000 shortfall on March 18, 2025, and included it in my 2025 taxable income.”

The prevention section shows you’ve implemented safeguards: “I have now set up automatic RMD distributions through my IRA custodian to ensure this never happens again,” or “I have hired a qualified financial advisor to manage all RMD calculations and distributions going forward.”

Supporting documentation strengthens your case. Attach letters from financial institutions acknowledging their error, medical records confirming illness, or documentation showing you relied on incorrect advice.

The IRS typically doesn’t respond if they grant the waiver. You simply never receive a bill for the penalty. If they deny the waiver, you’ll receive a notice with payment instructions and the opportunity to appeal.

Statute of Limitations Considerations

The SECURE 2.0 Act established definitive statute of limitations rules for RMD penalties that previously remained open indefinitely. This created planning certainty for taxpayers worried about old RMD mistakes.

For RMD shortfalls, the statute of limitations now runs three years from when you file your income tax return for that year. If you file your 2024 tax return on April 15, 2025, the IRS has until April 15, 2028, to assess the excise tax for any 2024 RMD shortfall.

The critical trigger is filing your Form 1040. Previously, the statute didn’t begin running until you filed Form 5329, which many taxpayers never filed when they missed RMDs. This meant the IRS could theoretically assess penalties decades later without limitation.

The new rule provides closure. If you missed an RMD but filed your tax return without Form 5329, the three-year clock still starts running from your Form 1040 filing date. After three years pass, the IRS cannot assess the penalty even though you never filed Form 5329 or paid the excise tax.

This doesn’t encourage ignoring RMDs because you still face income tax consequences and the penalty could be assessed within the three-year window. However, it provides certainty that old mistakes eventually become uncollectible.

For excess contributions to retirement accounts, a six-year statute of limitations applies instead of three years. This longer period reflects the IRS’s greater concern about contributions exceeding annual limits.

Real-World RMD Tax Scenarios and Examples

Concrete examples reveal how RMD taxation plays out across different retirement situations, income levels, and account combinations. These scenarios show the actual dollar impacts retirees face.

Scenario 1: Single Retiree, Traditional IRA, Moderate Income

Sarah turned 73 in 2025 with a traditional IRA balance of $400,000 on December 31, 2024. Her life expectancy factor from the IRS Uniform Lifetime Table is 26.5. Her 2025 RMD equals $400,000 ÷ 26.5 = $15,094.

Sarah receives $28,000 annually from Social Security and $22,000 from a small pension. Her combined income before the RMD equals $50,000 plus half her Social Security ($14,000), totaling $64,000.

Income Component	Amount	Tax Treatment
Social Security	$28,000	Up to 85% taxable based on combined income
Pension	$22,000	Fully taxable ordinary income
RMD	$15,094	Fully taxable ordinary income
Combined Income	$64,000	Determines Social Security taxation

The RMD pushes Sarah’s combined income to $64,000, which exceeds the $34,000 threshold where up to 85% of Social Security becomes taxable. Without the RMD, only $64,000 minus $15,094 = $48,906 in combined income would apply, still triggering Social Security taxation but at lower levels.

Her federal taxable income includes the full $15,094 RMD, the $22,000 pension, and approximately $23,800 of her Social Security benefits (85% of $28,000). After her $16,550 standard deduction for 2026 as a single filer over 65, her taxable income reaches approximately $44,344.

Using 2026 tax brackets for single filers, Sarah pays 10% on the first $11,925 ($1,193) and 12% on the remaining $32,419 ($3,890), for total federal tax of $5,083. Her effective rate on the RMD equals approximately 12% to 22% when accounting for how it increases Social Security taxation.

Sarah lives in Pennsylvania, which exempts retirement income. She pays no state tax on the RMD, saving approximately $1,510 compared to if she lived in a state with a 10% rate.

Scenario 2: Married Couple, Multiple Accounts, High Income

David and Linda both turned 73 in 2025. David has a traditional IRA worth $850,000 and a previous employer’s 401(k) worth $450,000. Linda has a traditional IRA worth $600,000. They file jointly with combined Social Security benefits of $65,000 and a pension of $55,000.

Account	December 31, 2024 Balance	Life Expectancy Factor	2025 RMD
David’s IRA	$850,000	26.5	$32,075
David’s 401(k)	$450,000	26.5	$16,981
Linda’s IRA	$600,000	26.5	$22,642
Total RMDs	$1,900,000	–	$71,698

David must take the $16,981 specifically from his 401(k) because employer plans can’t aggregate with IRAs. However, they can combine David’s $32,075 IRA RMD with Linda’s $22,642 IRA RMD and take the total $54,717 from either spouse’s IRA or split it between them.

Their combined income before RMDs equals $120,000 ($65,000 Social Security + $55,000 pension). The $71,698 in RMDs pushes their total income to $191,698.

Their combined income calculation adds $120,000 in Social Security and pension income, half of Social Security ($32,500), and the $71,698 RMD, totaling $224,198. This far exceeds the $44,000 threshold for married couples, making 85% of their Social Security benefits taxable.

Their taxable income includes:

• Pension: $55,000
• RMDs: $71,698
• Social Security (85%): $55,250
• Total: $181,948
• Less standard deduction: $35,400
• Taxable income: $146,548

Using 2026 married filing jointly brackets, they pay:

• 10% on first $23,850: $2,385
• 12% on next $73,100: $8,772
• 22% on remaining $49,598: $10,912
• Total federal tax: $22,069

Their effective rate on the RMDs equals approximately 31% because the distributions push income into the 22% bracket and increase Social Security taxation. They live in California with a 9.3% marginal state rate, adding another $6,668 in state taxes on the RMDs.

They also face IRMAA surcharges. Their $224,198 combined income for 2024 triggers the second IRMAA tier for their 2026 Medicare premiums. Each spouse pays an additional $81.20 monthly for Part B and approximately $14.50 monthly for Part D, totaling $2,296 annually in extra Medicare costs.

The RMDs create approximately $28,965 in combined federal, state, and IRMAA costs, representing a 40.4% effective rate on the $71,698 distribution.

Scenario 3: Still-Working Exception Utilization

Michael turned 74 in 2025 but continues working part-time as a consultant at his longtime employer, earning $45,000 annually. He owns less than 5% of the company. His 401(k) balance on December 31, 2024, equals $680,000.

Because Michael remains employed, he qualifies for the still-working exception. His 401(k) requires no RMD while he works, even though he’s past age 73. This delays approximately $28,000 in annual RMDs (his 401(k) balance of $680,000 divided by his life expectancy factor).

However, Michael also has a rollover IRA worth $325,000 from a previous employer. This IRA requires RMDs regardless of his current employment status. His IRA RMD equals $325,000 ÷ 25.5 = $12,745.

Income Source	Amount	Taxable
W-2 wages	$45,000	Yes
IRA RMD	$12,745	Yes
401(k) RMD	$0	Still-working exception applies
Total Income	$57,745	Taxable

Michael’s strategy defers $28,000 in taxable income annually by continuing part-time work. His marginal rate as a single filer equals 22%, saving approximately $6,160 annually in federal taxes alone plus state taxes and reduced Social Security taxation.

When Michael fully retires in 2027, his first 401(k) RMD comes due by April 1, 2028. At that point, he faces two 401(k) RMDs in 2028, one for 2027 and one for 2028, each approximately $30,000. This creates $60,000 in additional taxable income in 2028, potentially pushing him into higher brackets and triggering IRMAA surcharges.

The optimal strategy involves taking the first 401(k) RMD by December 31, 2027, to avoid the double distribution in 2028. This spreads the tax burden across two years instead of bunching it into one.

Strategic Tax Reduction Techniques

Multiple proven strategies exist to minimize the tax burden from required minimum distributions. Understanding these approaches and implementing them before and during your RMD years creates substantial long-term savings.

Qualified Charitable Distributions

QCDs allow you to direct up to $111,000 in 2026 from your IRA to qualified charities without including the distribution in your taxable income. This exclusion differs from a deduction, creating more valuable tax benefits.

You must be at least age 70½ to make QCDs. The distribution must go directly from your IRA trustee to a qualifying 501(c)(3) charity. You cannot receive the funds yourself and then donate them. The direct transfer requirement ensures the transaction qualifies for the income exclusion.

QCDs count toward satisfying your RMD requirement. If your RMD equals $35,000 and you make a $25,000 QCD, you need to take only an additional $10,000 taxable distribution to meet your obligation. The $25,000 QCD satisfies part of the RMD without adding to your income.

The tax benefits multiply beyond simple income exclusion. Because QCDs reduce your adjusted gross income, they prevent Social Security taxation triggers, avoid IRMAA surcharges, and keep you below various tax credit phaseout thresholds. Someone in the 24% federal bracket effectively saves 24% on their QCD amount, plus state taxes, plus indirect benefits from lower AGI.

The 2026 limit of $111,000 per person means married couples filing jointly can donate up to $222,000 through QCDs. Each spouse must use their own IRA for their portion of the total. You cannot make a $111,000 QCD from your spouse’s IRA to meet both limits.

Several restrictions apply:

Donor-advised funds cannot receive QCDs. Private foundations also don’t qualify. Supporting organizations likewise face exclusion. The charity must be a standard public charity eligible to receive tax-deductible contributions.

You cannot receive any benefit from the donation. Tickets to charity events, meals, or merchandise don’t qualify. The QCD must represent a pure donation with nothing received in return.

You cannot claim an itemized charitable deduction for QCD amounts. The IRS prohibits double benefits. The income exclusion replaces the deduction, and in most cases provides more value.

QCDs can only come from IRAs, not from 401(k)s or 403(b)s. However, you can roll your 401(k) to an IRA and then make QCDs from the IRA. The rollover must occur before year-end to allow QCDs from those funds.

Under 2026 tax changes, itemized charitable deductions face a 0.5% of AGI floor and a 35% cap for high earners. QCDs bypass both restrictions by excluding income rather than providing deductions, making them even more valuable.

Withholding Strategy for Tax Management

Strategic use of voluntary withholding from RMDs eliminates quarterly estimated payments and maximizes time your money remains invested. The key advantage comes from how the IRS treats withholding versus estimated payments.

Estimated tax payments carry specific deadlines: April 15, June 15, September 15, and January 15. Missing these deadlines triggers underpayment penalties calculated on the periods when payments fell short. The safe harbor rules require paying either 90% of current year taxes or 100% of prior year taxes (110% if prior year AGI exceeded $150,000 for married couples).

Withholding from retirement distributions counts as paid evenly throughout the year regardless of when the actual distribution occurs. This IRS rule creates planning opportunities. You can take your entire RMD in December, withhold enough to cover your full year’s tax liability, and the IRS treats it as if you paid quarterly.

The mathematical advantage is clear. Assume you owe $20,000 in total federal taxes for 2026. You could either:

Option A: Make four quarterly estimated payments of $5,000 each in April, June, September, and January, removing that money from your accounts throughout the year.

Option B: Take a $75,000 RMD in December, request 26.67% withholding ($20,000), receive $55,000, and let your IRA balance continue growing tax-deferred until December.

Option B keeps more money invested longer. If your IRA earns 6% annually, the extra months of tax-deferred growth on the $20,000 that would have gone to quarterly payments adds approximately $900 to your account value.

The withholding percentage can reach 100% if needed. If your RMD equals $60,000 and your total tax bill equals $50,000, you can request 83.33% withholding to cover taxes from all sources, not just the RMD itself.

This strategy works particularly well for retirees with irregular income. Business owners, real estate investors, and those with fluctuating capital gains struggle to estimate taxes accurately. The December RMD withholding covers any shortfall without penalties because the withholding satisfies safe harbor requirements.

One caution applies: your RMD must be large enough to cover your total tax liability through withholding. Someone with $150,000 in taxable income but only a $20,000 RMD cannot use this strategy to cover all taxes because withholding cannot exceed the distribution amount.

Pre-RMD Roth Conversion Planning

The years between retirement and your RMD age create prime opportunities for Roth conversions that permanently reduce future RMDs and their tax burden. Converting traditional IRA balances to Roth IRAs before age 73 shrinks the accounts subject to RMDs.

The conversion strategy works because Roth IRAs never require RMDs during your lifetime. Every dollar you convert from traditional to Roth eliminates future RMD obligations on that dollar plus all its future growth.

Consider someone retiring at 65 with an $800,000 traditional IRA. Without conversions, this balance grows to approximately $1,250,000 by age 73 assuming 6% annual returns. The first year RMD equals approximately $47,000, and RMDs grow annually as the balance increases and life expectancy factors decrease.

Instead, this person converts $75,000 annually for eight years from ages 65 to 72. The conversions trigger immediate taxation on $600,000 total but permanently remove this amount from the traditional IRA. By age 73, only $200,000 remains in the traditional IRA (less any growth), dropping the first RMD to approximately $7,500 instead of $47,000.

The strategy requires paying conversion taxes from non-retirement funds to maximize effectiveness. Using IRA money to pay conversion taxes reduces the amount actually reaching the Roth and creates unnecessary tax waste.

The optimal conversion amount each year fills your current tax bracket without pushing into the next. A married couple with $80,000 in annual income can convert approximately $16,950 while staying in the 12% bracket, assuming 2026 brackets. Converting more pushes income into the 22% bracket.

Conversions before Medicare eligibility avoid IRMAA complications. The two-year lookback for IRMAA means conversions at 63 don’t affect Medicare premiums until age 65, and by then you can control conversion amounts to manage IRMAA.

The tradeoff requires careful analysis. You pay taxes now on conversions versus later on RMDs. The strategy favors conversions when:

Current tax rates are lower than expected future rates. Tax brackets in retirement years may increase due to RMDs, Social Security, pensions, and investment income.

Future RMDs would trigger IRMAA surcharges. Converting enough to avoid IRMAA thresholds saves substantially on Medicare premiums.

You plan to leave retirement accounts to heirs. Non-spouse beneficiaries must empty inherited IRAs within 10 years, creating massive tax burdens. Inherited Roth IRAs distribute tax-free, providing much more after-tax value.

Account Consolidation and Simplification

Strategic consolidation of retirement accounts before RMDs begin simplifies administration and opens planning opportunities. The key involves understanding which accounts can aggregate and which cannot.

Rolling old 401(k) accounts from previous employers to your current employer’s 401(k) before retirement allows the still-working exception to apply to all the consolidated funds. This works only if your current employer’s plan accepts rollovers, which most do.

Someone with three 401(k)s from previous employers totaling $600,000 faces RMDs on all three once they reach age 73. Rolling them into their current employer’s 401(k) and continuing to work part-time defers all $600,000 from RMD requirements during employment.

However, rolling old 401(k)s to IRAs prevents using the still-working exception because IRAs require RMDs regardless of employment status. This makes the IRA rollover decision crucial before retirement.

Consolidating multiple traditional IRAs simplifies RMD calculations. Instead of calculating separate RMDs for five IRAs and tracking five different account balances, consolidation into one IRA requires one calculation and one distribution. The tax treatment remains identical, but administration becomes easier.

The same applies to consolidating multiple inherited IRAs from the same decedent. You can combine them to simplify the 10-year distribution requirements and annual RMD calculations.

One consolidation trap involves mixing IRAs with different characteristics. Non-deductible contributions create basis that you must track using Form 8606. Consolidating an IRA with basis with one without basis complicates the tax reporting because you must now track the combined basis across the merged account.

Minimizing State Tax Impact Through Residency

Your state of residence at the time you take RMDs determines state tax treatment. Moving to a state with no income tax or retirement income exemptions before RMDs begin creates permanent annual savings.

The nine states with no income tax save the most. Florida’s popularity among retirees stems partly from eliminating state tax on the $50,000 to $100,000 in annual RMDs many retirees face. This saves $3,000 to $6,000 annually compared to states with 6% income tax rates.

The four states exempting all retirement income provide similar benefits while maintaining income taxes on other sources. Illinois residents pay 4.95% on wages and business income but zero on IRA and 401(k) distributions. Someone with $500,000 in traditional IRA balances saves approximately $100,000 in lifetime state taxes through this exemption.

Michigan’s new 2026 exemption creates planning opportunities for current residents. Waiting until January 1, 2026, to take your first RMD if you turn 73 in 2025 allows Michigan’s full exemption to apply to all future RMDs.

Establishing residency requires more than declaring intent. Most states use multiple factors: physical presence for at least 183 days annually, driver’s license and vehicle registration, voter registration, homestead exemption claims, and filing state tax returns as residents. Simply buying a vacation home in Florida while maintaining your primary home in New York doesn’t eliminate New York’s tax claims on your RMDs.

Domicile changes should occur before the tax year you take large distributions. Moving to Florida in November 2026 after taking your 2026 RMD in April provides no 2026 tax benefit because you were a different state’s resident when the distribution occurred.

Common RMD Tax Mistakes to Avoid

Retirees frequently make preventable errors with RMD taxation that cost thousands in unnecessary taxes and penalties. Understanding these common mistakes helps you avoid them.

Taking RMDs Too Early in the Year

Taking your RMD in January removes money from your tax-deferred account for the entire year when it could have continued growing. Assuming a 6% annual return, a $40,000 RMD taken in January versus December costs approximately $2,400 in lost growth.

The December strategy provides maximum tax-deferred growth while meeting the December 31 deadline. The only exception is your first RMD if you choose the April 1 extension, but even then, taking it by December 31 of your age 73 year avoids the two-RMD problem the following year.

Forgetting Aggregation Rules Lead to Incorrect Withdrawals

The different aggregation rules for IRAs versus 401(k)s confuse many retirees. Taking your entire RMD from one 401(k) when you own two 401(k)s violates the rules because 401(k) RMDs must come from their specific accounts.

Similarly, combining IRA RMDs with 403(b) RMDs doesn’t work. While IRAs aggregate with each other and 403(b)s aggregate with each other, you cannot aggregate across these account types.

Someone with a $15,000 IRA RMD and a $10,000 403(b) RMD who takes $25,000 from their IRA has satisfied only the IRA requirement. They still owe $10,000 from the 403(b) and face penalties on the $10,000 shortfall.

Mixing Up Account Balances for Calculations

Using current account values instead of prior year December 31 balances creates incorrect RMD amounts. Your 2026 RMD uses your December 31, 2025, balance, not your current balance in 2026 when you take the distribution.

Account values fluctuate daily with market changes. Using the wrong balance date leads to taking too little and facing penalties or taking unnecessary excess that increases taxes without providing required credit.

Your IRA custodian typically provides the correct balance and calculated RMD amount in January. Verify their calculation matches your December 31 balance to catch any errors.

Not Coordinating Roth 401(k) Distributions

Before 2024, Roth 401(k) accounts required RMDs that many retirees missed because they assumed Roth accounts never required distributions. The SECURE 2.0 elimination applies only to 2024 and later years.

Anyone who turned 73 in 2023 and delayed their first Roth 401(k) RMD to April 1, 2024, must still take that distribution even though the law changed. Missing this first RMD triggers the 25% penalty.

Similarly, not rolling Roth 401(k)s to Roth IRAs before 2024 meant taking unnecessary RMDs and paying taxes on any earnings growth since those earnings distributions might have faced taxation if the five-year rule wasn’t satisfied.

Believing the Still-Working Exception Applies to All Accounts

The still-working exception applies only to your current employer’s plan, not to IRAs or previous employers’ plans. Many retirees working part-time mistakenly believe this exempts all their retirement accounts from RMDs.

The 5% ownership rule also catches business owners. Owning 5% or more of the company eliminates the still-working exception even if you’re employed. This includes ownership by certain family members counted toward your interest.

Taking RMDs from the Wrong Spouse’s IRA

Married couples sometimes take one spouse’s RMD from the other spouse’s IRA, which doesn’t satisfy the requirement. Each person’s RMD must come from their own accounts, though each person can decide which of their IRAs provides their own distributions.

If a husband owes a $20,000 RMD and takes it from his wife’s IRA, both spouses now have RMD shortfalls. His own IRA still requires its full RMD, and his wife’s distribution reduces her balance but doesn’t count toward her separate RMD obligation.

Missing QCD Opportunities Due to Timing

QCDs must occur before taking your regular RMD for the full tax benefit. If you take your full $40,000 RMD in January and then make a $20,000 QCD in March, the January distribution already hit your taxable income. The March QCD counts toward next year’s RMD.

The correct sequence involves making the QCD first. Your $20,000 QCD in March satisfies part of your RMD obligation tax-free, then you take the remaining $20,000 later in the year as a regular taxable distribution.

Failing to Adjust Withholding for Total Tax Liability

Many retirees withhold only the standard 10% from RMDs without calculating their actual tax liability. If you fall in the 24% federal bracket plus 5% state rate, 10% withholding leaves you 19 percentage points short, creating a tax bill and potential underpayment penalties.

Calculate your total tax liability including RMDs, Social Security, pensions, and investment income. Set withholding at a percentage that covers your total obligation, not just taxes on the RMD itself.

Frequently Asked Questions

Does taking more than my RMD reduce future required amounts?

No. Taking more than your current year’s RMD does not reduce future RMDs or provide credit for excess withdrawals. Each year’s RMD calculates independently using that year’s December 31 balance divided by that year’s life expectancy factor. Extra distributions reduce your balance but future RMDs still use the same formula without any credit for previous excess amounts.

Can I reinvest my RMD after taking it?

Yes. You can reinvest RMD amounts in taxable brokerage accounts immediately after withdrawal. However, you cannot roll RMDs back into retirement accounts because they fail to qualify as eligible rollover distributions. The RMD amount faces taxation regardless of reinvestment, but reinvesting allows continued investment growth on after-tax dollars outside the retirement account.

Do RMDs count toward IRA contribution limits?

No. RMDs represent required withdrawals that do not affect your ability to make annual IRA contributions based on earned income. If you continue working past age 73 with earned income, you can still contribute up to $8,000 annually to IRAs in 2026 including catch-up amounts, completely separate from RMD obligations that require distributions.

Can I use my RMD to make a Roth conversion?

No. You must take your RMD first as a taxable distribution before making any Roth conversions for that year. The IRS ordering rules require that the first dollars withdrawn in any year satisfy your RMD obligation and cannot be converted to Roth. After satisfying your RMD, you can convert additional traditional IRA amounts to Roth.

Does the first-time homebuyer exception apply to RMDs?

No. The first-time homebuyer exception allowing penalty-free early withdrawals before age 59½ does not apply to RMDs because RMDs occur after age 73 when the 10% early withdrawal penalty no longer applies anyway. The two provisions serve different purposes and never interact since RMDs begin after the age when early withdrawal penalties end.

Are RMDs subject to Social Security and Medicare taxes?

No. RMDs face ordinary income taxation but not FICA taxes because retirement distributions do not constitute earned income from employment or self-employment. Only wages, salaries, and self-employment income trigger Social Security and Medicare taxes. However, RMDs do affect Social Security benefit taxation and Medicare IRMAA surcharges through the income they add to your tax return.

Can I satisfy my RMD with in-kind distributions?

Yes. You can satisfy RMDs by transferring securities or other assets from your IRA to a taxable account instead of selling them first and distributing cash. The transferred assets’ fair market value on the transfer date counts toward your RMD requirement. You owe taxes on the fair market value, and this value becomes your cost basis in the taxable account.

Do employer contributions to my 401(k) stop once RMDs begin?

No. Employers must continue matching contributions and other plan contributions for employees taking RMDs if the plan document requires such contributions. The requirement to take RMDs does not eliminate your eligibility for employer contributions as long as you continue working and participating in the plan under its normal rules.

Can I split my RMD across multiple withdrawals during the year?

Yes. You can take your RMD in any combination of withdrawals throughout the year as long as the total by December 31 meets or exceeds the required amount. Some retirees take monthly distributions to create steady income while others take quarterly or annual lump sums. The timing flexibility allows matching distributions to cash flow needs.

What happens if my IRA loses value after calculating my RMD?

Your RMD obligation remains unchanged because the calculation uses the prior December 31 balance regardless of subsequent market losses. If your account was worth $500,000 on December 31 requiring a $20,000 RMD, you must withdraw $20,000 even if the account drops to $450,000 by the time you take the distribution. Market declines do not reduce current year RMD requirements.

Do state tax withholding rules differ from federal?

Yes. Some states do not allow voluntary withholding from retirement distributions even when federal withholding applies. State withholding availability depends on your state of residence and whether the IRA custodian offers state withholding services for that state. Many taxpayers must make state estimated tax payments separately even when federal withholding covers their federal liability.

Can I donate my entire RMD through a QCD if it exceeds my required amount?

Yes. You can donate amounts exceeding your RMD up to the $111,000 annual QCD limit in 2026. The full QCD amount excluded from income provides tax benefits, and the portion satisfying your RMD meets that obligation while additional amounts simply represent tax-free charitable gifts that do not carry forward to future years.

What if my employer plan doesn’t allow the still-working exception?

Plans must specifically adopt the still-working exception in their plan documents. If your employer’s plan does not include this provision, you must take RMDs from the plan starting at age 73 even while continuing employment. Check your summary plan description or contact your plan administrator to determine if your plan offers this exception.

Are inherited RMDs eligible for QCDs?

Yes. Non-spouse beneficiaries taking RMDs from inherited IRAs can use QCDs for these distributions if they meet the age 70½ requirement. The QCD counts toward satisfying the annual RMD requirement under the 10-year rule while excluding the donated amount from taxable income, providing the same tax benefits as QCDs from owned IRAs.

Does moving to another state mid-year affect RMD taxation?

Yes. Most states use part-year residency rules that prorate income based on residency periods. If you move from New Jersey to Florida on July 1, your RMD typically faces New Jersey tax on the portion attributable to your New Jersey residency period and Florida tax on the remainder, which equals zero. The specific calculation depends on each state’s part-year residency rules.
