Inherited IRA Ten-Year Rule Tax Implications

The inherited IRA ten-year rule requires most non-spouse beneficiaries to deplete inherited retirement accounts within ten years of the account holder’s death, with all withdrawals taxed as ordinary income. Understanding which heirs are subject to this rule, how the tax bill accumulates, and techniques to spread distributions over the decade can materially reduce the total tax burden.

The SECURE Act’s Ten-Year Window

The SETTING EVERY COMMUNITY UP FOR RETIREMENT Enhancement Act (SECURE Act) of 2019 fundamentally changed how inherited IRAs are taxed. Before the law, non-spouse heirs could use a “stretch IRA” strategy, withdrawing only required minimum distributions each year and allowing the account to compound for decades—sometimes 30 or 40 years—while deferring most of the tax bill.

The new rule says: withdraw everything by the end of the tenth calendar year following the death. If the original account holder died in 2024, the December 31st of the tenth year out is the deadline. There is no tax advantage to spreading withdrawals evenly over the decade; the only requirement is that the account be empty by that final date. The IRS does not mandate annual minimum withdrawals during those ten years—you can take the full account in year one, or wait until December of year ten and withdraw everything then.

However, there’s a critical exception: if the beneficiary is a spouse, a minor child, a person with a disability, or a person with a chronic illness, different rules often apply. Spouses can roll an inherited IRA into their own account as if they had inherited their own money. Minor children have options that differ. It’s the other beneficiaries—the adult children, grandchildren, friends, and non-qualified heirs—who face the hard ten-year deadline.

Taxation of Distributions

Every dollar withdrawn from an inherited traditional IRA or inherited 401k-plan is taxed as ordinary income. This is a crucial distinction from a step-up in basis rule, which applies to inherited stocks or real estate. When you inherit a taxable stock portfolio, the cost basis “steps up” to the market value on the date of death, so you owe no tax if you sell immediately.

Inherited IRAs receive no such benefit. If the deceased contributed $100,000 over many years and the account grew to $300,000 by death, all $300,000 is taxable to the beneficiary as it is withdrawn. The $200,000 of gains sits in a tax-deferred account that was never taxed in the original account holder’s lifetime, so the IRS will collect it from the beneficiary.

The tax is due in the year of withdrawal. Withdraw $50,000 in 2025, and you owe ordinary income tax on that $50,000 at your marginal tax rate. If you’re in the 24% federal bracket, that $50,000 withdrawal triggers $12,000 of federal tax, plus any applicable state income tax.

Required Minimum Distributions During the Ten Years

The rules are more nuanced than “no RMDs until the deadline.” The IRS has clarified that the RMD rules still apply to inherited IRAs during the ten-year window, depending on whether the original account holder had begun taking RMDs at death.

If the deceased was older than 73 (the current age at which RMDs begin) and had already started withdrawing, the beneficiary must continue taking RMDs each year during the ten-year period, calculated using a life-expectancy table. If the deceased was younger than 73 and had not yet begun RMDs, then no RMDs are required during the ten-year window—but the entire account must still be gone by the deadline.

This distinction matters. If RMDs apply, you’re forced to spread withdrawals; if they don’t, you could theoretically take everything in a single lump sum in year ten (though that would generate a massive one-year tax bill).

Tax Deferral and Bunching Strategies

The most common problem is income bunching. If you inherit a $500,000 IRA and wait until year ten to withdraw the full amount, you’ll report $500,000 of taxable income in that year. Depending on your other income, this could push you into a much higher tax bracket, trigger net investment income tax, or subject you to alternative minimum tax.

A deliberate withdrawal strategy can reduce this harm. Spread $500,000 evenly over ten years—$50,000 per year—and you’ll stay in a more predictable tax bracket each year. Some beneficiaries time distributions around low-income years, early retirement, or changes in filing status.

Roth conversions are sometimes considered. You can roll an inherited traditional IRA into a new inherited Roth IRA, paying tax on the conversion in the year it happens, but then the remaining ten-year window applies to the Roth and all future withdrawals from that Roth are tax-free. This accelerates the tax bill upfront but can be beneficial if you expect to be in a higher bracket later or if the IRA has significant growth potential.

Another tactic: coordinate withdrawals with charitable giving. If you plan to donate to charity anyway, charitable distributions can sometimes provide deductions that offset the tax on inherited IRA withdrawals in the same year.

Spouse Beneficiaries and Exceptions

Spouse beneficiaries have substantially better options. A spouse can elect to treat the inherited IRA as their own, meaning they become the account holder, not a beneficiary. They can then delay RMDs until their own age 73, and they can potentially pass the account to their own heirs under their own estate plan. This is an enormous advantage and effectively gives the spouse decades more to defer taxes.

Minor children of the account holder are also exempt from the ten-year rule, though the rules are complex. Once they reach the age of majority (18 or 21, depending on the state), an accelerated schedule often applies.

Beneficiaries with disabilities or chronic illnesses, as defined by the IRS, can sometimes treat the inherited IRA more like a retirement account and use their own life expectancy for RMD calculations, rather than facing the hard ten-year deadline.

For all other beneficiaries, the ten-year rule applies with no flexibility.

State Tax and Planning Implications

Federal income tax is not the only concern. Most states tax distributions from inherited IRAs as ordinary income. Some states have no income tax, which creates opportunities. A beneficiary resident in Florida, Tennessee, or another no-income-tax state will pay federal tax on inherited IRA withdrawals but no state tax, making the burden lighter than an equivalent withdrawal in a high-tax state like New York or California.

A few beneficiaries have relocated specifically to time inherited IRA withdrawals in low-tax jurisdictions, though the tax code contains residency and domicile rules that require genuine relocation and not mere temporary presence.

Coordination with Your Estate Plan

Inherited IRAs now represent a much less attractive bequest. Since the ten-year rule eliminates most of the tax-deferral advantage that made IRAs appealing to leave to heirs, some estate planners recommend that clients leave retirement accounts to a surviving spouse and direct other assets—particularly taxable investments that qualify for step-up in basis—to other heirs. This shifts the tax-deferral advantage to the spouse and minimizes the total family tax bill.

Conversely, if you inherit an IRA and have the ability to withdraw funds to charity, placing a charitable bequest of inherited IRA funds can be highly tax-efficient and accomplish your charitable goals.
