How Do You Claim the IRD Deduction on an Inherited IRA? (w/Examples) + FAQs

This article reflects federal rules and selected state rules as of June 2026 and covers tax years 2025 and 2026. Tax law changes — confirm current figures before you file.

Quick Answer

You claim the IRD deduction on Schedule A, line 16 (“Other Itemized Deductions”), of your Form 1040. You may deduct the share of federal estate tax the inherited IRA caused, but only if the decedent’s estate actually paid federal estate tax. You must itemize, and you deduct it in the same year you report the IRA income.

For tax year 2025, federal estate tax only hits estates above $13.99 million, so this deduction belongs to a small but high-value group of heirs. The trap is real money: when a big estate already paid up to 40% estate tax on an IRA, and you then pay income tax on the same dollars as you withdraw them, that is double taxation — and the IRC Section 691(c) deduction is your only legal way to claw part of it back.

Most eligible heirs miss it. As The Finance Observer notes, roughly 90% of qualifying beneficiaries never claim it, often because tax software never asks for the estate’s Form 706 data. Here is what you will learn:

What “IRD” Actually Means

Income in respect of a decedent (IRD) is income the person who died had earned or was owed, but had not yet been taxed on, when they died. A traditional IRA is the textbook example: the original owner never paid income tax on the contributions or the growth, so that tax debt does not vanish at death — it transfers to you, the beneficiary.

This is why an inherited traditional IRA is fully taxable to you as you withdraw it. The IRS treats those withdrawals as ordinary income, exactly as the original owner would have. As the Bogleheads wiki explains, IRD keeps its tax character when it passes to the heir.

The problem is that the same IRA also counts in the decedent’s gross estate for estate tax. So a large IRA can be taxed twice: once by the estate tax when the owner dies, and again by your income tax as you draw it down. The IRD deduction exists to soften that overlap. The misconception to kill early: many heirs think “I inherited it, so it is tax-free.” It is not — an inherited traditional IRA is one of the most heavily taxed assets you can receive, and your next step is to find out whether estate tax was paid so you can recover part of it.

The Two Taxes: Estate Tax vs. Income Tax

To claim the deduction, you must see the two separate taxes clearly, because the deduction only bridges one specific gap.

Federal Estate Tax (the gate)

Federal estate tax is a tax on the transfer of a deceased person’s total wealth above an exemption. For tax year 2025, the basic exclusion amount is $13.99 million per person. For deaths in 2026, the One Big Beautiful Bill Act (OBBBA) permanently raised it to $15 million per person, indexed for inflation after 2026.

This is the gate to the whole deduction. If the estate was below the exemption, it paid no federal estate tax, so there is nothing for the IRD deduction to recover — your deduction is zero. The consequence of missing this point is wasted effort: heirs of modest estates sometimes hunt for a deduction that legally cannot exist.

Income Tax (yours to pay)

Income tax is what you pay on each dollar you withdraw from the inherited IRA. It lands on your Form 1040 at your ordinary rates, reported from the Form 1099-R the custodian sends you. The IRD deduction reduces this income tax bill by giving you an itemized deduction for the estate tax the IRA already triggered.

Which Situation Applies to You?

The answer depends entirely on one fact about the estate, not about you. Find your branch below before you do any math.

The estate paid federal estate tax (filed Form 706 with a balance due). You likely qualify. Get the IRD computation from the executor and skip to the calculation section. This is the only branch where the deduction exists.
The estate filed Form 706 only to elect portability, owing no tax. No federal estate tax was paid, so there is no IRD deduction, even though a return was filed.
The estate was below the exemption and filed no Form 706. No deduction. Your IRA withdrawals are simply taxable income.
You inherited a Roth IRA. Roth withdrawals are generally income-tax-free, so there is no income tax to offset and the IRD deduction does not apply to you.
You inherited a 401(k), annuity, or deferred comp from a taxable estate. You may also qualify — the same Section 691(c) deduction covers these. See the section on other IRD assets.

How the IRD Deduction Is Calculated

The math has two layers: first the executor finds the total deduction the IRA generated, then you apply a fixed percentage to each withdrawal you take. The core method is a “with and without” calculation described in IRS Revenue Ruling 2005-30.

Step 1 — The “With and Without” Estate Tax

The executor computes the estate tax with all the IRD assets included, then recomputes it without them. The difference is the estate tax attributable to the IRD — that total is the lifetime IRD deduction pool the beneficiaries share.

For example, if including a $2 million IRA pushed the estate tax up by $800,000, then $800,000 is the total IRD deduction tied to that IRA. The consequence of skipping this step is that you have no defensible number, and the IRS can disallow the deduction for lack of substantiation. Your move: ask the executor for the IRD figure in writing, ideally pulled straight from the filed Form 706.

Step 2 — Your Deduction Percentage

Divide the IRA’s IRD-related estate tax by the IRA’s value to get a percentage. Using the example above, $800,000 of estate tax on a $2 million IRA equals a 40% deduction rate. The wfp-taxes 5-step guide lays out this same ratio method.

You then apply that 40% to each withdrawal. The misconception here is that you deduct the whole $800,000 in year one — you do not. You can only deduct the IRD portion in the year you actually report the matching IRA income, and you cannot claim it in a year you take no withdrawal.

Step 3 — Spread It Over Every Withdrawal

Because the SECURE Act forces most non-spouse heirs to empty inherited IRAs within 10 years, you will likely take several withdrawals. Each one carries its own slice of the deduction. If you withdraw $200,000 this year at a 40% rate, you deduct $80,000 on this year’s Schedule A.

The deduction continues, year after year, until you have either emptied the account or used up the full IRD deduction pool. Track the running total carefully, because once you have deducted the entire estate-tax amount, the deduction stops even if money remains in the account.

A Fully Worked Example (Real Dollars)

Meet Daniel, who in 2025 inherited a $2,000,000 traditional IRA from his late aunt. Her total estate was $20 million, well above the $13.99 million 2025 exemption, so her estate paid federal estate tax.

The executor ran the “with and without” calculation and found that including the IRA added $800,000 of federal estate tax. Daniel’s deduction rate is therefore $800,000 ÷ $2,000,000 = 40%.

In 2025, Daniel withdrew $250,000 from the inherited IRA. Here is his math, step by step:

Taxable IRA income reported on Form 1040: $250,000.
IRD deduction = 40% × $250,000 = $100,000 on Schedule A, line 16.
Net amount actually taxed at his ordinary rate: $250,000 − $100,000 = $150,000.

If Daniel sits in the 37% federal bracket, the deduction saves him 37% × $100,000 = $37,000 in federal income tax this year alone. Over the full 10-year drawdown of the $2 million, the deduction pool is the entire $800,000, which at a 37% rate is worth about $296,000 in lifetime tax savings. Skipping it would mean voluntarily handing that money back to the IRS.

Scenario Tables

These three patterns cover the situations heirs most often face.

Scenario 1 — Large Taxable Estate

Beneficiary’s Action	Tax Result
Confirms estate paid federal estate tax on Form 706	Deduction is available
Gets the 40% IRD rate from the executor	Has a substantiated percentage
Withdraws $250,000 and deducts $100,000 on Schedule A	Taxes only $150,000, saving ~$37,000 at 37%

Scenario 2 — Estate Below the Exemption

Beneficiary’s Action	Tax Result
Inherits a $400,000 IRA from a $3 million estate	No federal estate tax was paid
Looks for an IRD deduction	Deduction is $0 — it legally cannot exist
Withdraws $50,000	Full $50,000 is taxable income, no offset

Scenario 3 — Heir Takes the Standard Deduction

Beneficiary’s Action	Tax Result
Qualifies for a real IRD deduction	Deduction exists but must be itemized
Files using the standard deduction instead	Loses the entire IRD deduction that year
Switches to itemizing on Schedule A	Captures the deduction and lowers the bill

More Named Examples

Maria inherited a $1.2 million IRA in 2025 from a $16 million estate. Her executor calculated a 38% IRD rate. She withdrew $300,000, deducted $114,000 on Schedule A line 16, and cut her taxable IRA income to $186,000 — a result her tax software never prompted her to claim until she fed it the Form 706 figure.

James inherited a $500,000 IRA, but his father’s estate was only $4 million and paid no federal estate tax. James correctly found that his IRD deduction was zero. Rather than fight for a deduction that does not exist, he focused on spreading withdrawals across the 10-year window to manage his income tax brackets.

Priscilla inherited both a traditional IRA and her late husband’s deferred compensation, all from a taxable estate. Because Section 691(c) covers deferred comp too, she claimed the IRD deduction on both income streams, not just the IRA.

How to Claim It: The Form Walkthrough

The deduction lives in one specific place, and tax software rarely surfaces it, so you usually enter it by hand.

Where It Goes on Your Return

You report your inherited IRA income from the Form 1099-R onto your Form 1040 as ordinary income first. Then you claim the deduction on Schedule A, line 16, “Other Itemized Deductions,” writing a short description such as “Federal Estate Tax on IRD” and the dollar amount. Northern Trust confirms line 16 is the correct line, and a tax-practitioner walkthrough shows the narrative-line requirement.

Why the 2% Floor and AMT Do Not Hurt You

This is a miscellaneous itemized deduction not subject to the 2%-of-AGI floor. As the Journal of Accountancy explains, that classification means two big advantages: it survived the TCJA suspension of 2%-floor deductions that ran through 2025, and you can claim it even if you owe the alternative minimum tax. So this deduction is fully available for both 2025 and 2026 returns.

If You Inherited Through an Estate or Trust

When the IRA income flows through an estate or trust to you, the IRD deduction passes out on your Schedule K-1, typically reported so you can carry it to your own Schedule A. Match the K-1 figure to the year you report the related income.

Deadlines, Costs, and Timing

You claim the deduction on the return for the tax year of the withdrawal, due April 15 of the following year (so a 2025 withdrawal goes on the return due April 15, 2026). Miss it, and you generally have three years to file an amended Form 1040-X to recover it.

Doing it yourself is free if you already itemize, but the “with and without” estate-tax computation usually requires the executor’s Form 706 and often a CPA. Expect to pay a few hundred to a few thousand dollars for a professional to compute and document the IRD rate — worth it when the deduction is six figures.

Other IRD Assets That Qualify

The IRD deduction is not limited to IRAs. As Michael Kitces’ analysis notes, it also applies to employer retirement plans like 401(k)s, inherited non-qualified annuities, employer non-qualified stock options, deferred compensation, accrued bonuses, and unpaid wages.

If you inherited several of these from one taxable estate, each carries its own IRD slice and its own deduction. The practical step is to ask the executor for an IRD breakdown by asset, so you do not overlook a stream that also qualifies for the line 16 deduction.

Does Your State Allow the IRD Deduction?

Start with the federal rule, then check your state separately, because conformity varies and guessing costs money.

The federal Section 691(c) deduction only ever offsets federal estate tax. It does not apply to state inheritance or state estate taxes — a point The Finance Observer stresses directly. So if your state charges its own death tax, the federal IRD deduction will not recover it.

For state income tax, whether you get a matching deduction depends on whether your state conforms to the federal itemized deduction rules. Twelve states plus D.C. impose their own estate tax (such as New York, Massachusetts, Oregon, and Washington), and several others impose an inheritance tax (such as Pennsylvania, New Jersey, Kentucky, and Nebraska). States that follow the federal Schedule A generally allow the IRD deduction on the state return; states with their own deduction systems may not. Check your state Department of Revenue’s instructions for the year you file, because a no-income-tax state like Texas or Florida raises no state-level IRD issue at all.

Mistakes to Avoid

Taking the standard deduction. The IRD deduction requires itemizing, so the standard deduction wipes it out entirely — you lose every dollar of it that year.
Assuming an inherited IRA is tax-free. It is fully taxable as ordinary income, and ignoring that can leave you with a surprise tax bill plus penalties.
Hunting for a deduction on a small estate. If the estate paid no federal estate tax, the deduction is zero, and claiming one anyway invites IRS disallowance.
Deducting the whole pool in year one. You can only deduct the IRD slice that matches the income you reported that year, so over-deducting triggers an IRS adjustment.
Letting software skip it. Most programs never ask for Form 706 data, so the deduction silently disappears unless you enter it by hand on line 16.
Confusing federal and state death taxes. Section 691(c) only offsets federal estate tax, so trying to deduct a state inheritance tax will be denied.
Losing the records. Without the executor’s IRD computation and Form 706, you cannot substantiate the percentage, and the IRS can throw out the deduction.

Do’s and Don’ts

Do ask the executor for the IRD figure in writing — it is the foundation of every year’s deduction.
Do itemize when the IRD deduction beats your standard deduction, because that is the only way to capture it.
Do track your running deduction total, since it stops once you have used the full estate-tax pool.
Do amend a prior return within three years if you missed the deduction, to recover real cash.
Do apply the deduction to non-IRA IRD assets too, because the same rule covers annuities and deferred comp.
Don’t assume your state follows the federal rule — confirm with your state Department of Revenue.
Don’t apply the deduction in a year you took no withdrawal, because there is no matching income to offset.
Don’t rely on the custodian’s 1099-R to show the deduction; it never will.
Don’t deduct against state death taxes, since Section 691(c) is federal-only.
Don’t guess the percentage — use the executor’s “with and without” math to stay defensible.

Pros and Cons of Claiming It

Pro: It can recover up to roughly 40% of an inherited IRA’s value in tax, because that is the top federal estate tax rate.
Pro: It is not subject to the 2% AGI floor, so high earners keep the full benefit.
Pro: It works even under the AMT, unlike most miscellaneous deductions.
Pro: It applies to many asset types, multiplying the savings across an estate.
Pro: It survived the TCJA and is available for both 2025 and 2026 returns.
Con: It requires itemizing, which not everyone benefits from.
Con: It demands the executor’s Form 706 data, which can be hard to obtain.
Con: It only exists for estates that actually paid federal estate tax, a small group.
Con: The “with and without” calculation is complex and often needs a CPA.
Con: It must be tracked across years, adding recordkeeping work to each drawdown.

What to Do Next

Confirm whether the decedent’s estate filed a Form 706 and paid federal estate tax — this is your gate.
Ask the executor, in writing, for the IRD deduction amount and the IRA’s deduction percentage.
Gather your Form 1099-R, the Form 706 figures, and any Schedule K-1 from an estate or trust.
Each year you withdraw, multiply the withdrawal by your IRD rate and enter it on Schedule A, line 16, with the label “Federal Estate Tax on IRD.”
Check your state Department of Revenue rules for whether the deduction carries to your state return.
Call a CPA or tax attorney if the estate is large, the records are missing, or you need to amend a prior return — the six-figure stakes justify the fee.

FAQs

What line do I claim the IRD deduction on? Schedule A, line 16 (“Other Itemized Deductions”) of Form 1040. Write a short description such as “Federal Estate Tax on IRD” with the dollar amount. You must itemize to claim it.

Can I take the IRD deduction if I use the standard deduction? No. The IRD deduction is an itemized deduction. If you take the standard deduction, you lose it for that year. You must itemize on Schedule A to claim it.

Is the IRD deduction subject to the 2% AGI floor? No. It is a miscellaneous itemized deduction not subject to the 2% floor, so it survived the TCJA suspension and remains fully claimable for tax years 2025 and 2026.

How much is the IRD deduction worth? Up to roughly 40% of the inherited IRA’s value, because that is the top federal estate tax rate. The exact percentage equals the estate tax the IRA caused divided by the IRA’s value.

Do I qualify if the estate paid no federal estate tax? No. The deduction only offsets federal estate tax actually paid. For 2025, estates under $13.99 million owe none, so heirs of those estates have no IRD deduction.

Does the IRD deduction apply to a Roth IRA? No, generally not. Roth withdrawals are income-tax-free, so there is no income tax to offset. With no income tax due, there is nothing for the IRD deduction to reduce.

Can I claim it in a year I take no IRA withdrawal? No. You deduct the IRD portion only in the year you report the matching IRA income. No withdrawal means no income and no deduction that year.

Does the IRD deduction cover state inheritance tax? No. Section 691(c) offsets only federal estate tax. State estate or inheritance taxes are not covered by the federal IRD deduction.

What if I forgot to claim it last year? File Form 1040-X to amend. You generally have three years from the original filing date to claim a refund for a missed IRD deduction.

What records do I need to claim it? The executor’s IRD computation and the filed Form 706. These substantiate your deduction percentage. Without them, the IRS can disallow the deduction for lack of proof.

Does the deduction apply to inherited 401(k)s or annuities? Yes. Section 691(c) covers 401(k)s, non-qualified annuities, deferred compensation, stock options, and unpaid wages — not just IRAs — when the estate paid federal estate tax.

Did the 2026 OBBBA estate tax change affect this deduction? The exemption rose to $15 million per person for 2026 deaths. Fewer estates now owe estate tax, so fewer heirs qualify, but the deduction itself remains unchanged for those who do.
