Yes, defined benefit plans have required minimum distribution (RMD) rules. IRC Section 401(a)(9) mandates that all qualified retirement plans—including traditional pensions—must begin distributing benefits by a specific age. Failure to comply triggers a 25% excise tax penalty on the amount not withdrawn.
According to the Bureau of Labor Statistics, only 15% of private industry workers had access to a defined benefit plan in March 2024. This makes understanding the RMD rules even more critical for those fortunate enough to have pension coverage.

The Federal Law That Governs Defined Benefit Plan RMDs
Treasury Regulation §1.401(a)(9)-6 provides the specific guidance for RMDs in defined benefit plans. This regulation requires that distributions of a participant’s entire interest must be paid in the form of periodic annuity payments. The payments must cover the participant’s life, the joint lives of the participant and beneficiary, or a “period certain” that does not exceed specific lengths.
The purpose of RMD rules is to prevent tax-deferred retirement accounts from being used as permanent tax shelters. Congress wants the IRS to eventually collect taxes on contributions and earnings that grew without taxation. Defined benefit plans receive the same favorable tax treatment as 401(k)s and IRAs, so they face the same distribution requirements.
The required beginning date (RBD) is April 1 of the year following the later of: (1) the calendar year the participant reaches the applicable age, or (2) the calendar year the participant retires from the employer maintaining the plan. A participant cannot delay distribution beyond this date regardless of personal preference.
How the SECURE Acts Changed RMD Ages for Pension Participants
The RMD starting age has increased multiple times in recent years. The original SECURE Act of 2019 raised the age from 70½ to 72. Then SECURE 2.0 Act of 2022 raised it again.
| Birth Year | RMD Starting Age | First RMD Deadline |
|---|---|---|
| Before July 1, 1949 | 70½ | Already passed |
| July 1, 1949 – Dec 31, 1950 | 72 | Already passed |
| Jan 1, 1951 – Dec 31, 1959 | 73 | April 1 after turning 73 |
| Jan 1, 1960 or later | 75 | April 1 after turning 75 |
The IRS finalized these regulations in 2024, confirming that individuals born in 1959 follow the age 73 rule. Some ambiguity existed in the original SECURE 2.0 language, but the IRS clarified this issue through proposed technical corrections.
Anyone who turned 72 in 2022 or earlier follows the old rules. Their RMDs already began. Anyone turning 72 in 2023 or later benefits from the delayed start date.
How RMDs Work Differently in Defined Benefit Plans vs. Defined Contribution Plans
The calculation method is the primary difference between these two plan types. Defined contribution plans (like 401(k)s) use the account balance method. You divide your December 31 balance by a life expectancy factor from IRS tables.
Defined benefit plans use the annuity method instead. There is no individual account balance to divide. The plan promises a specific benefit amount based on formulas involving salary history and years of service.
| Feature | Defined Benefit Plan | Defined Contribution Plan |
|---|---|---|
| RMD calculation method | Annuity payments over life | Account balance ÷ life expectancy |
| Individual account | No | Yes |
| RMD amount | Monthly/annual pension payment | Calculated each year |
| Investment risk | Employer bears risk | Employee bears risk |
| Aggregation allowed | No | No (except 403(b)s and IRAs) |
Annuity payments from a defined benefit plan automatically satisfy the RMD rules. Once monthly or annual payments begin and continue for the participant’s life (or joint lives), no additional calculation is necessary. The pension payment is the RMD.
This creates a significant administrative difference. With a 401(k), you must actively calculate and request your RMD each year. With a pension, the plan handles it automatically through regular payments.
The Annuity Method: How Defined Benefit Plan RMDs Are Calculated
The annuity method requires that benefits be distributed as periodic payments over the participant’s remaining lifetime. These payments must be non-increasing or only increase under specific allowable circumstances (like cost-of-living adjustments).
Treasury Regulation §1.401(a)(9)-6 specifies that distributions must be in the form of periodic annuity payments for the employee’s life, the joint lives of the employee and beneficiary, or over a period certain. The payments cannot extend beyond the life expectancy of the participant and designated beneficiary.
Example: Maria’s Pension RMD
Maria worked for a manufacturing company for 30 years. Her defined benefit plan provides $2,500 per month beginning at age 65. She retired at 65 and started receiving payments immediately.
| Situation | RMD Status |
|---|---|
| Monthly pension payment | $2,500 |
| Annual pension total | $30,000 |
| RMD requirement | Satisfied automatically |
| Additional action needed | None |
Maria’s monthly payments satisfy her RMD obligation. She does not need to calculate anything or request additional distributions. The plan’s formula-based payment meets the annuity distribution requirement.
When Lump Sum Distributions Change the RMD Calculation
Some defined benefit plans offer participants the option to receive their benefit as a lump sum instead of monthly payments. This creates a more complex RMD calculation scenario.
If a participant elects a lump sum after their required beginning date, part of that lump sum is considered an RMD. The RMD portion cannot be rolled over to an IRA or another qualified plan. The plan can calculate this RMD portion using one of two methods.
The first method treats the lump sum as an account balance and applies the defined contribution plan rules. Divide the lump sum by the applicable life expectancy factor.
The second method treats one year of annuity payments as the RMD. This is often called the annuity method for lump sums.
Example: Savannah’s Lump Sum Election
Savannah, age 74, retired from her employer’s defined benefit plan. She has been receiving $2,000 monthly payments. Her former employer offers her a lump sum buyout of $300,000.
| Calculation Method | RMD Amount | Rollover Eligible |
|---|---|---|
| Account balance method | $12,605 ($300,000 ÷ 23.8) | $287,395 |
| Annuity method | $24,000 ($2,000 × 12 months) | $276,000 |
The annuity method produces a larger RMD because it treats an entire year of payments as the required distribution. Savannah should understand both calculations before making her election, as they significantly affect how much she can roll over tax-free.
The “Still Working” Exception for Pension Participants
The still working exception allows certain employees to delay RMDs from their current employer’s plan until they actually retire. This exception applies only to qualified plans (including defined benefit plans), not to IRAs.
To qualify for this exception, a participant must: (1) still be employed by the company sponsoring the plan, and (2) own less than 5% of the business. The IRS code does not define what “still working” means in terms of hours. Even part-time employment qualifies.
| Ownership Level | Still Working Exception Available? |
|---|---|
| Less than 5% owner | Yes |
| 5% or more owner | No |
| Self-employed sole proprietor | No |
| Partner with 5%+ interest | No |
The attribution rules make the 5% ownership threshold more complex than it appears. If family members own shares in the company, their ownership may be attributed to the employee for purposes of this test.
Example: Robert’s Delayed RMD
Robert is 75 years old and still works full-time for ABC Corporation. He owns no stock in the company. His employer maintains a defined benefit pension plan.
| Factor | Robert’s Situation |
|---|---|
| Age | 75 |
| Ownership in company | 0% |
| Employment status | Active full-time |
| RMD required now? | No |
| When RMD begins | April 1 after retirement year |
Robert can delay his pension distributions until he actually retires. Once he separates from service, his first RMD must be taken by December 31 of that year (or April 1 of the following year if it is his first RMD).
How 5% Owners Face Different RMD Rules
Participants who own 5% or more of the business cannot use the still working exception. They must begin RMDs by April 1 of the year following the year they reach the applicable age (73 or 75 depending on birth year), regardless of employment status.
This rule prevents business owners from indefinitely delaying taxes by staying employed. The attribution rules under IRC Section 318 determine ownership. Stock owned by a spouse, children, grandchildren, or parents may count toward the 5% threshold.
Example: Dr. Thompson’s Mandatory RMD
Dr. Thompson is 74 years old and owns 15% of a medical practice. The practice sponsors a defined benefit plan. She plans to work until age 80.
| Factor | Dr. Thompson’s Situation |
|---|---|
| Age | 74 |
| Ownership percentage | 15% |
| Employment status | Active, plans to work until 80 |
| Still working exception? | Not available |
| RMD status | Must have already begun |
Even though Dr. Thompson is still working, she must take RMDs because she owns more than 5% of the business. Her RMD began when she reached age 73.
How Vesting Schedules Affect Pension RMDs
A critical distinction for defined benefit plan RMDs is that only vested amounts are subject to the distribution requirements. Non-vested balances do not count.
Most defined benefit plans use a three-year cliff vesting schedule. This means participants become 100% vested after completing three years of service. Before that point, they have no vested benefit and therefore no RMD obligation for that plan.
| Vesting Status | RMD Required? |
|---|---|
| 0% vested | No |
| 50% vested | Yes, on vested portion |
| 100% vested | Yes, on entire benefit |
This creates a potential planning opportunity. An older business owner starting a new defined benefit plan might delay vesting to postpone RMDs. However, this strategy has limits. Upon reaching normal retirement age as defined by the plan, participants must become 100% vested.
Example: Frank’s New Pension Plan
Frank is 72 years old and starts a new business. He establishes a defined benefit plan effective January 1, 2024, with three-year cliff vesting and service before the plan’s effective date excluded.
| Year | Vesting Status | RMD Required? |
|---|---|---|
| 2024 | 0% | No |
| 2025 | 0% | No |
| 2026 | 100% | Yes |
Frank avoids RMDs for two years because he has no vested benefit during that period. In 2026, when he becomes fully vested, RMDs must begin. The compressed timeframe may result in larger annual distributions than if he had been vested from the start.
Cash Balance Plans: A Hybrid Approach to RMDs
Cash balance plans are a type of defined benefit plan that resembles a defined contribution plan. Each participant has a hypothetical “account balance” that grows with pay credits and interest credits.
Despite the account-like structure, cash balance plans follow the defined benefit RMD rules. The plan uses the annuity method to calculate RMDs, not the account balance method.
This can produce confusing results. A participant might see a $500,000 “account balance” on their statement but receive an RMD calculated as an annuity over their remaining life expectancy. The annuity-based RMD will typically be much higher than what the account balance method would produce.
| Plan Type | RMD Method | Distribution Period |
|---|---|---|
| Traditional DB plan | Annuity | Life expectancy |
| Cash balance plan | Annuity | Life expectancy |
| 401(k) plan | Account balance | Uniform lifetime table |
Example: Comparing RMD Amounts
A participant has $700,000 in retirement savings. Compare the RMD under different plan types.
| Plan Type | Calculation | Annual RMD |
|---|---|---|
| Cash balance (DB rules) | $700,000 ÷ 7 years | $100,000 |
| 401(k) (DC rules) | $700,000 ÷ 26.5 years | $26,415 |
The defined benefit RMD is approximately four times higher because the distribution period is much shorter. Cash balance plan participants should plan for this significant tax impact.
Government Pension Plans and RMD Rules
Federal, state, and local government pension plans generally follow the same RMD rules as private sector defined benefit plans. The SECURE Act changes to RMD ages apply to governmental plans.
The Thrift Savings Plan (TSP) for federal employees automatically calculates and distributes RMDs for separated participants age 73 and older. This happens without the participant needing to request it. The TSP uses the IRS Uniform Lifetime Table for calculations.
The Federal Employees Retirement System (FERS) basic annuity is a defined benefit plan. Once annuity payments begin, they satisfy the RMD requirement. Participants who separate before the annuity starts must understand when their RBD occurs.
Important: Federal retirees often have both a FERS annuity and TSP account. The FERS annuity satisfies RMD requirements for that plan automatically. The TSP has separate RMD obligations that must be tracked independently.
Church Pension Plans: Special Considerations
Church plans may have different rules depending on their structure. A 403(b)(9) retirement income account is a special type of church plan with unique provisions.
The SECURE Act increased the RMD age from 70½ to 72 for church plan participants, just like other qualified plans. SECURE 2.0 further increased it to 73 or 75 based on birth year.
Church plans that elect to be subject to ERISA follow standard rules. Non-electing church plans have more flexibility but still must comply with basic RMD requirements under the Internal Revenue Code.
One unique benefit: ordained ministers may claim a housing allowance exemption on distributions from a church 403(b)(9) plan. This benefit is not available from IRAs or non-church retirement plans.
The QJSA Requirement and RMDs
Defined benefit plans must offer a Qualified Joint and Survivor Annuity (QJSA) as the default payment form for married participants. The QJSA provides lifetime payments to the participant and a survivor benefit (at least 50%) to the spouse after death.
The QJSA automatically satisfies RMD requirements because it provides lifetime payments. The participant does not need to make any additional calculations or elections to comply with RMD rules.
| QJSA Feature | Requirement |
|---|---|
| Survivor annuity minimum | 50% of participant’s benefit |
| Survivor annuity maximum | 100% of participant’s benefit |
| Spousal consent to waive | Required (notarized) |
| RMD compliance | Automatic |
A participant can waive the QJSA and choose another payment form, but only with written spousal consent witnessed by a notary public or plan representative. Alternative forms must still comply with RMD rules.
QDROs and Pension RMDs: Rules for Alternate Payees
A Qualified Domestic Relations Order (QDRO) can divide a pension benefit between a participant and a former spouse (alternate payee) during divorce proceedings.
Alternate payees have their own RMD obligations. While the participant is still living, the alternate payee must begin receiving RMDs based on the participant’s required beginning date. The alternate payee’s portion is treated as if it were a separate benefit.
| Situation | Alternate Payee RMD Rule |
|---|---|
| Participant alive, before RBD | No RMD required yet |
| Participant alive, after RBD | RMD required |
| Participant deceased | 10-year or life expectancy rule applies |
The plan administrator determines whether an order qualifies as a QDRO. Once qualified, the alternate payee may elect their own form of payment, subject to plan provisions and RMD requirements.
The Penalty for Missing a Defined Benefit Plan RMD
The excise tax for missing an RMD was 50% of the shortfall amount before 2023. SECURE 2.0 reduced this to 25%. If corrected within two years, the penalty drops further to 10%.
| When RMD Was Missed | Penalty Rate |
|---|---|
| 2022 or earlier | 50% of missed amount |
| 2023 or later | 25% of missed amount |
| Corrected within 2 years | 10% of missed amount |
The participant (not the plan) bears responsibility for this excise tax. However, a plan’s failure to make timely RMDs can jeopardize its qualified status, creating problems for all participants.
Example: The Cost of a Missed RMD
John’s required pension payment was $4,000 monthly ($48,000 annually). He failed to receive any payments in 2024 due to an administrative error.
| Scenario | Penalty Amount |
|---|---|
| No correction | $12,000 (25% × $48,000) |
| Corrected within 2 years | $4,800 (10% × $48,000) |
| Waiver granted by IRS | $0 |
John should file Form 5329 and request a waiver if the mistake was due to reasonable cause.
How to Correct a Missed Pension RMD
The IRS may waive the excise tax if you can demonstrate reasonable cause for the failure and show that you are taking steps to remedy the shortfall.
Step-by-Step Correction Process:
- Contact your plan administrator immediately
- Request the missed distribution as soon as possible
- File IRS Form 5329 with your tax return
- Enter “RC” (reasonable cause) and the waiver amount on line 54
- Attach a letter explaining why the RMD was missed
- Describe the corrective steps you have taken
The plan administrator must also correct the error. For defined benefit plans, this may involve paying missed annuity payments with interest or providing an actuarial increase to future payments.
For plans that pay lump sums, the administrator must determine which portion represents the RMD (ineligible for rollover) versus the rollover-eligible amount. This calculation can be complex and may require actuarial assistance.
Mistakes to Avoid with Defined Benefit Plan RMDs
Pension RMD mistakes can be costly. The following errors occur frequently and have serious consequences.
Mistake #1: Assuming the “Still Working” Exception Applies to You
Many participants believe they can delay RMDs because they are still employed. However, if you own 5% or more of the business, this exception does not apply. The consequence is accumulated penalties for each year you failed to take the required distribution.
Mistake #2: Rolling Over the Entire Lump Sum
When taking a lump sum from a defined benefit plan after your RBD, a portion is the RMD and cannot be rolled over. Rolling over that portion creates an excess IRA contribution subject to a 6% annual penalty until corrected.
Mistake #3: Ignoring Non-Vested Benefits
Some participants do not realize that only vested benefits trigger RMD obligations. Starting distributions before vesting may not be required, and doing so voluntarily could affect your tax planning.
Mistake #4: Assuming Annuity Payments Are Automatic
While defined benefit plans should automatically begin distributions, administrative errors happen. The participant is ultimately responsible for ensuring RMDs are taken, even if the plan fails to initiate payments.
Mistake #5: Confusing the Two-RMD Year
In your first RMD year, you may delay the first distribution until April 1 of the following year. However, this means taking two RMDs in one year—potentially pushing you into a higher tax bracket.
Pros and Cons of Defined Benefit Plan RMD Rules
| Pros | Cons |
|---|---|
| Automatic compliance through annuity payments satisfies RMD rules without annual calculations | Higher RMD amounts due to shorter distribution periods than defined contribution plans |
| Still working exception allows delayed RMDs for non-owners still employed | 5% owners cannot delay RMDs regardless of employment status |
| Vesting schedules can defer RMD start dates for new plan participants | Once fully vested, larger RMDs may be required due to compressed timeframe |
| No aggregation confusion because each plan stands alone | Cannot aggregate RMDs across multiple defined benefit plans |
| Guaranteed lifetime payments provide income security | Less flexibility in distribution timing compared to 401(k)s |
Do’s and Don’ts for Defined Benefit Plan RMDs
| Do | Don’t |
|---|---|
| Do verify your ownership percentage annually to confirm still working exception eligibility | Don’t assume you qualify for the still working exception without checking ownership attribution rules |
| Do coordinate your pension RMD with other retirement account RMDs for tax planning | Don’t take a lump sum without understanding which portion is the RMD and cannot be rolled over |
| Do contact your plan administrator well before your required beginning date | Don’t wait for the plan to contact you about starting distributions |
| Do file Form 5329 immediately if you miss an RMD and request a penalty waiver | Don’t ignore a missed RMD hoping the IRS will not notice |
| Do consider the tax impact of delaying your first RMD until April 1 (two RMDs in one year) | Don’t delay your first RMD without calculating the combined tax effect |
Real-World Scenario: Sarah’s Pension Decision
Sarah is 73 years old and recently retired from a large corporation after 35 years. Her defined benefit pension will pay $3,500 monthly for life, with a 75% survivor benefit for her husband.
| Decision Point | Sarah’s Choice | Consequence |
|---|---|---|
| Start pension immediately | Yes | RMD satisfied automatically |
| Roll portion to IRA | Not possible (no lump sum option) | N/A |
| Delay to maximize payment | No (already at NRA) | Would have increased payments but created RMD urgency |
Sarah’s decision is straightforward because her plan does not offer a lump sum option. Her monthly annuity payments satisfy the RMD requirement without any additional action.
Real-World Scenario: Michael’s Complex Situation
Michael is 76 years old, owns 8% of his company, and has both a defined benefit pension and a 401(k) at the same employer.
| Account | RMD Status | Action Required |
|---|---|---|
| Defined benefit pension | Must begin—5% owner rule applies | Take annuity or lump sum with RMD portion |
| 401(k) account | Must begin—5% owner rule applies | Calculate and withdraw annually |
Because Michael owns more than 5% of the business, he cannot use the still working exception for either plan. His pension RMD is calculated using the annuity method, while his 401(k) RMD uses the account balance method. He must take distributions from both plans separately—aggregation is not permitted.
Real-World Scenario: Emma’s Lump Sum vs. Annuity Choice
Emma is 74 and was just offered a choice: continue her $2,200 monthly pension or accept a $400,000 lump sum buyout.
| Option | Annual Amount | RMD Portion | Tax Impact |
|---|---|---|---|
| Monthly annuity | $26,400 | Full payment is RMD | Spread over 12 months |
| Lump sum (annuity method) | $26,400 | $26,400 not rollable | Immediate tax on RMD |
| Lump sum (account method) | $16,528 | $16,528 not rollable | Smaller immediate tax |
Emma should consult with her actuary to determine which RMD calculation method her plan uses. The choice significantly affects how much she can roll over tax-free and her immediate tax liability.
When Plan Administrators Must Act Without Participant Direction
Plan administrators face a dilemma when participants reach their RBD but fail to make a benefit election. In absence of an election, the plan must automatically pay the QJSA or other default form specified in the plan document.
The plan cannot simply not pay because the participant is unresponsive. Failure to commence RMDs puts the plan’s qualified status at risk. The plan sponsor faces potential disqualification, which affects all participants negatively.
| Participant Status | Plan Administrator Duty |
|---|---|
| Responsive, elected benefit | Pay as directed |
| Unresponsive, known location | Begin default payments by RBD |
| Missing (cannot locate) | Document search efforts extensively |
The IRS issued specific guidance on missing participants. Plans that take prescribed search steps will not be challenged for RMD failures due to inability to locate participants.
Actuarial Increases for Delayed Pension Payments
When a defined benefit plan fails to begin payments at the required time, the participant’s benefit must be actuarially increased to account for the delayed start. This ensures the participant is not penalized for the plan’s error.
The actuarial increase compensates for the payments the participant should have received. The plan must also pay missed payments with interest or provide an equivalent benefit adjustment.
| Correction Element | Purpose |
|---|---|
| Actuarial increase | Compensates for shorter payment period |
| Missed payment interest | Provides time value of delayed money |
| Future payment adjustment | Ensures total benefit value is preserved |
These corrections can be administratively complex and may trigger benefit restriction rules under IRC Section 436 for underfunded plans.
FAQs
Do all pension plans have RMD requirements?
Yes. All qualified defined benefit pension plans must comply with IRC Section 401(a)(9) RMD rules, requiring distributions begin by the required beginning date.
Can I delay my pension RMD if I am still working?
Yes, but only if you own less than 5% of the business. The still working exception allows non-owners to delay RMDs until actual retirement.
Is my monthly pension payment considered an RMD?
Yes. Lifetime annuity payments from a defined benefit plan automatically satisfy RMD requirements without additional calculations needed.
What happens if my pension plan fails to pay me by my RBD?
You face a 25% excise tax on the missed amount. The plan also risks disqualification. File Form 5329 to request a penalty waiver.
Can I roll over my entire pension lump sum to an IRA?
No. The portion representing the RMD cannot be rolled over. Only the excess above the RMD is eligible for tax-free rollover.
Do RMD rules apply to government pensions?
Yes. Federal, state, and local government pension plans follow the same RMD rules as private sector defined benefit plans.
Does vesting affect when my pension RMD begins?
Yes. Only vested amounts are subject to RMD rules. Non-vested benefits do not trigger RMD obligations until vesting occurs.
Are cash balance plan RMDs calculated differently?
No. Despite having account-like features, cash balance plans use the annuity method for RMDs, typically producing higher required distributions.
Can my spouse’s consent waive the QJSA requirement?
Yes. A married participant can waive the QJSA with written spousal consent witnessed by a notary public or plan representative.
What is the RMD penalty if I fail to take enough?
The penalty is 25% of the shortfall amount. It reduces to 10% if corrected within two years of the missed deadline.
Do church pension plans have different RMD rules?
No. Church plans follow the same basic RMD age requirements. However, clergy may claim housing allowances on 403(b)(9) distributions.
Can I take more than my RMD from my pension?
No. Defined benefit plans pay fixed amounts based on the plan formula. You cannot simply request additional distributions.
Does an alternate payee under a QDRO have RMD requirements?
Yes. Alternate payees must begin RMDs based on the original participant’s required beginning date while the participant is living.
Will delaying my first RMD save me money?
No. Delaying until April 1 of the following year means two RMDs in one calendar year, potentially increasing your tax bracket.
Can I aggregate my pension RMD with my IRA RMD?
No. Each defined benefit plan requires separate compliance. You cannot combine RMDs across different plan types.
