How Much Tax Do You Pay on an Inherited IRA?

The short answer: ordinary income tax at your marginal federal rate — no special rate, no capital-gains treatment, no step-up in basis.

Why inherited IRAs are taxed as ordinary income

Traditional IRAs are funded with pre-tax dollars — contributions were deducted in the year they were made, and all investment growth was tax-deferred. The IRS has never collected tax on those dollars. When you distribute them — whether as the original owner or as an inheriting beneficiary — that deferred tax bill comes due.

There is no step-up in basis for IRA assets. Step-up applies to securities held in taxable accounts (stocks, real estate) where the owner paid tax on the original purchase price. IRA assets were never taxed at any point, so there is nothing to step up. Every dollar distributed is a new taxable event.¹

This is different from inheriting a taxable brokerage account, where the inherited securities get a new cost basis at the date-of-death fair market value, eliminating the embedded gain. That favorable treatment does not exist for IRAs.

The 2026 federal tax brackets (what your distributions land in)

All inherited IRA distributions are taxed as ordinary income under the same brackets that apply to wages, interest, and other regular income. For 2026 per IRS Rev. Proc. 2025-32:²

Single filers

Married filing jointly

The 2026 standard deduction is $16,100 for single filers and $32,200 for married filing jointly.² These figures are applied to gross income to arrive at taxable income. If you itemize, your actual deductions replace the standard deduction.

Worked examples: the tax on different distribution amounts

Example 1: Moderate distribution — stays in the 22% bracket

Single filer, age 56. You inherited a $500,000 IRA from your father in 2025 and decide to distribute $50,000/year. You have $75,000 in W-2 income.

• Gross income: $75,000 + $50,000 = $125,000
• Standard deduction: −$16,100
• Taxable income: $108,900
• Tax: $9,238 (brackets 10–22%) + $3,264 (24% on $108,900 − $105,700 = $3,200) = ~$12,502
• Marginal rate on the IRA distribution: almost entirely 22%, with a small amount at 24%
• Tax on the $50,000 IRA distribution specifically: approximately $11,000–$11,500

At roughly 22–23% effective rate on the distribution, this is a manageable outcome. Strategy focus: keep annual income under $105,700 taxable income ($121,800 gross for single, after $16,100 standard deduction) to stay out of the 24% bracket.

Example 2: Larger distribution — pushes into the 24% bracket

Married filing jointly, age 62. You inherited a $900,000 IRA from your mother. You're retired with $90,000 in pension income and distribute $100,000/year from the inherited IRA.

• Gross income: $90,000 + $100,000 = $190,000
• Standard deduction: −$32,200
• Taxable income: $157,800
• All of this falls within the 22% bracket ($100,801–$211,400 for MFJ)
• Tax: $24,800 × 10% + $76,000 × 12% + $57,000 × 22% = $2,480 + $9,120 + $12,540 = $24,140
• Marginal rate on the IRA distribution: 22%
• Tax attributable to the $100,000 distribution: approximately $22,000

In this scenario, both spouses' retirement income and the full inherited IRA withdrawal fit comfortably within the 22% bracket. The key risk: once Social Security begins, that income pushes AGI higher and may create bracket pressure in later years of the 10-year window.

Example 3: Year-10 lump sum — the bracket disaster

Same person from Example 2 (MFJ, $90,000 pension) defers the entire $900,000 inherited IRA and takes it in year 10. At 7% average annual growth, the balance has grown to approximately $1,770,000.

• Gross income: $90,000 + $1,770,000 = $1,860,000
• Standard deduction: −$32,200
• Taxable income: $1,827,800
• The incremental dollars above $768,700 taxable income are taxed at 37%
• Estimated additional federal tax from the IRA distribution vs. no distribution: ~$540,000+
• Effective rate on the inherited IRA distribution alone: roughly 30–31%

The year-10 deferral strategy turns a 22% problem into a 35–37% problem — on a much larger balance. This is the "10-year tax bomb" that fee-only inherited IRA specialists are designed to prevent. Use the 10-Year Withdrawal Optimizer to model what your specific balance looks like under equal distributions vs. deferral.

No 10% early withdrawal penalty

Regardless of your age, distributions from an inherited IRA are permanently exempt from the 10% early withdrawal penalty under IRC § 72(t)(2)(A)(ii) — the "death exception."³ You do not need to be 59½. You do not need to take substantially equal periodic payments (SEPP/72(t) rules do not apply). The death exception eliminates the penalty entirely.

This is meaningfully different from an early withdrawal from your own IRA, where the 10% penalty applies unless you qualify for a specific exception. For inherited IRAs, the exception is automatic.

Income tax still applies — the penalty exemption doesn't make distributions tax-free. But it removes the additional 10% layer that often discourages younger beneficiaries from withdrawing strategically in early years.

Three factors that can make the effective rate higher than your bracket

1. IRMAA — Medicare premium surcharges

Inherited IRA distributions count toward Medicare's Modified Adjusted Gross Income (MAGI) calculation. IRMAA surcharges apply if MAGI exceeds $109,000 (single) or $218,000 (MFJ) in 2026. The surcharges apply two years after the high-income year — so a large 2026 distribution raises your 2028 Medicare Part B and Part D premiums.⁴

At the first IRMAA tier, Part B premiums increase by approximately $65/month and Part D by $12/month — $924/year per person on Medicare. Higher tiers can add $5,800+ per year. This "hidden" cost is on top of your income tax. See the full analysis: Inherited IRA and Medicare IRMAA — how the 10-year window interacts with premium tiers.

2. Social Security benefit taxation

If you receive Social Security, inherited IRA distributions can trigger or increase the taxation of your benefits. Under IRC § 86, provisional income above $34,000 (single) or $44,000 (MFJ) causes 85% of Social Security benefits to be included in gross income. The effective marginal rate on inherited IRA distributions in this "85% zone" can reach 40.7% for a 22%-bracket taxpayer — because each dollar of IRA income also pulls in 85 cents of previously untaxed Social Security.⁵ See the full breakdown: Inherited IRA and Social Security Benefit Taxation.

3. State income taxes

Federal brackets don't tell the full story. Most states tax inherited IRA distributions as ordinary income at state rates — ranging from 0% (Florida, Texas, Nevada, Washington state, and a handful of others) to 13.3% (California top rate). A combined federal + state marginal rate of 40–50% on incremental inherited IRA distributions is realistic for high-income residents of California, New York, or New Jersey. Five states also impose a separate inheritance tax on the account balance, distinct from income tax on withdrawals. Full guide: State Taxes on Inherited IRA.

What lowers your effective tax rate

Spreading distributions across 10 years

The single most impactful tax move is avoiding year-10 deferral. Equal annual distributions spread the ordinary income across 10 tax years, keeping each year's incremental income in lower brackets. For a $500,000 inherited IRA, equal distributions of roughly $60,000–$70,000/year are far more efficient than a single $930,000+ year-10 withdrawal.

Front-loading distributions in low-income years

If your other income varies over the 10-year window — career transition, retirement, years without Social Security — front-loading larger distributions in those lower-income years can shift more of the inherited IRA into the 12% or low-22% bracket. See specific strategies: Inherited IRA Tax Strategies — six techniques for minimizing the 10-year tax bill.

Coordinating Roth conversions (not from the inherited IRA, from your own)

Non-spouse beneficiaries cannot Roth-convert an inherited IRA. But they can coordinate inherited IRA withdrawals — which fill the lower part of their bracket — with Roth conversions from their own traditional IRA that fill the remaining bracket space. The indirect effect: you use the inherited IRA window to accomplish Roth conversions at known, lower rates, reducing your own future RMD burden. Tool: Roth Conversion Coordinator.

Qualified Charitable Distributions (age 70½+)

If you are 70½ or older, you can direct up to $111,000/year (2026) from your own IRA to charity as a QCD — excluded entirely from gross income.⁶ You cannot QCD from an inherited IRA, but the coordination benefit is real: using QCDs from your own IRA for charitable giving frees bracket space for inherited IRA distributions, while keeping AGI lower to avoid IRMAA and Social Security taxation triggers.

Inherited Roth IRA: different rules

If you inherited a Roth IRA (not a traditional IRA), the tax treatment is fundamentally different. Qualified distributions from an inherited Roth IRA are completely income-tax-free — because the original owner already paid tax on contributions, and growth was tax-free.⁷

A distribution from an inherited Roth IRA is "qualified" (and therefore tax-free) if the Roth IRA has satisfied its 5-year holding period. Critically, the 5-year clock runs from when the original owner first opened any Roth IRA — not from when you inherited it. Most Roth IRAs inherited from parents who have been contributing for years are already past the 5-year mark.

The 10-year depletion rule still applies to inherited Roth IRAs for non-EDB beneficiaries — you must empty the account by year 10. But unlike inherited traditional IRAs, no income tax is due on distributions from a qualified Roth. The optimal strategy is typically to defer to year 10 and take a large tax-free lump sum. See the complete rules: Inherited Roth IRA Guide.

After-tax basis: if the inherited IRA had non-deductible contributions

If the person you inherited from made non-deductible IRA contributions and properly tracked them on Form 8606, a portion of the inherited IRA has "basis" — after-tax money that was already taxed. Distributions of that basis are tax-free; only distributions of the pre-tax amounts and growth are taxable.

The mechanics require a separate pro-rata calculation for the inherited IRA, independent of your own IRA's basis calculation. Many beneficiaries overpay by thousands because they never claim this basis, or because the decedent's Form 8606 records are lost. Full guide: Inherited IRA After-Tax Basis and Form 8606.

The bottom line on tax planning

The question isn't just "what rate do I pay?" — it's "how do I sequence distributions to minimize the total tax paid over the full 10-year window?" For most inherited IRAs of $200,000 or more, the difference between a thoughtless default strategy (equal 10-year withdrawals or year-10 deferral) and a deliberate plan can be $30,000–$100,000 in avoidable taxes. The planning variables — your other income, future bracket trajectory, Social Security timing, IRMAA exposure, state taxes, and Roth conversion opportunity — are exactly what a fee-only inherited IRA specialist models.
