Inherited IRA Rules in 2026: The 10-Year Rule Explained for Non-Spouse Beneficiaries

If you inherited a Traditional IRA in 2026 from a parent or other non-spouse, you must empty the entire account by December 31 of the 10th calendar year following the original owner's death. If your parent had already started taking Required Minimum Distributions before they died, you also have to take an annual RMD every year from year 1 through year 9. Miss either deadline and the IRS hits you with a 25% excise tax on the amount you should have withdrawn.

That is the rule in one paragraph. The rest of this article explains who it applies to, who is exempt, the two distribution paths, the tax math, and the three most expensive mistakes new beneficiaries make in 2026.

Who is subject to the 10-year rule?

The 10-year rule applies to most non-spouse beneficiaries of IRAs and 401(k)s where the original owner died after December 31, 2019. It was created by the original SECURE Act of 2019, modified by SECURE Act 2.0 in late 2022, and finalized by IRS regulations issued in July 2024.

The IRS sorts beneficiaries into three groups. The group you fall into determines your distribution rules.

Most readers of this article are in the middle group: an adult child inheriting from a parent. That is where the 10-year rule lives. If you fall into one of the EDB exceptions, see the section below.

How the 10-year rule actually works in 2026

This is where the IRS confused the entire industry for four years. The rule depends on whether the deceased account owner had already reached their Required Beginning Date (RBD) for taking RMDs from their own account before they died.

The RBD is currently April 1 of the year after the account owner turns 73. Under SECURE Act 2.0, that age rises to 75 for individuals who turn 73 after 2032.

There are two distribution paths depending on whether the original owner had crossed that line.

Path 1: Original owner died BEFORE their RBD

If the deceased had not yet reached age 73 (or had reached 73 but not yet hit April 1 of the following year) at the time of death, the rule is MORE simple:

• No annual RMDs are required during the 10-year window.
• The entire account balance must be distributed by December 31 of the 10th calendar year after death.
• You can take it all out in year 1, year 10, or anything in between.

Example: Your mother died in 2024 at age 67 with a $400,000 Traditional IRA. She had not started RMDs. You inherited the full account. You have until December 31, 2034 to empty it. You can wait until 2034 and take the entire balance, spread it evenly, or any combination.

Path 2: Original owner died AFTER their RBD

If the deceased had already reached their RBD and was taking RMDs from their own IRA before death, the rule is harsher:

• Annual RMDs are required in years 1 through 9 of the 10-year window, calculated using the Single Life Expectancy Table.
• The entire remaining balance must still be distributed by December 31 of the 10th calendar year.
• This is sometimes called the "10-year rule with annual RMDs" or the "at-least-as-rapidly" rule.

Example: Your father died in 2024 at age 78 while already taking his own RMDs. You inherited his $600,000 Traditional IRA. You must take an annual RMD every year from 2025 through 2033, and the account must be fully empty by December 31, 2034.

The IRS waived the year 1-9 RMD requirement during the rule's transition period through Notices 2022-53, 2023-54, and 2024-35. Those waivers ended. 2025 was the first year the annual RMD requirement was actually enforced. 2026 is year 2 of enforcement, with no further waivers expected.

What is the penalty if I miss an RMD?

The penalty for missing an inherited IRA RMD in 2026 is a 25% excise tax on the amount you should have withdrawn but did not. Under SECURE Act 2.0, this was reduced from the previous 50% penalty, but 25% on a $30,000 missed RMD is still $7,500 in pure penalty, on top of the income tax you eventually owe when you do withdraw.

If you correct the error within two years by withdrawing the missed amount and filing Form 5329, the penalty drops to 10%. The correction window is real, but do not rely on it. Set a calendar reminder for December 1 of every year you have an inherited IRA.

Who qualifies as an Eligible Designated Beneficiary?

There are exactly five categories of Eligible Designated Beneficiary, and only these five. If you are not one of them, you are subject to the 10-year rule.

1. Surviving spouse of the decedent. Spouses have additional options including rolling the inherited IRA into their own IRA. See the article on inherited 401(k)s for the spouse-specific rules, which differ in important ways.
2. Minor child of the decedent. Stretch RMDs over the child's life expectancy until they reach age 21, after which the 10-year clock starts. Minor grandchildren do not qualify.
3. Disabled individual. As defined by IRC Section 72(m)(7).
4. Chronically ill individual. As defined by IRC Section 7702B(c)(2), with documentation requirements.
5. Beneficiary not more than 10 years younger than the decedent. Common in sibling inheritance situations.

If you qualify as an EDB, you can elect to stretch RMDs over your single life expectancy starting in the year after the decedent's death. This is significantly more tax-efficient than the 10-year rule for most beneficiaries because it spreads taxable income over decades instead of years.

The 10-year rule for inherited Roth IRAs

The 10-year rule applies to inherited Roth IRAs too, but the analysis is completely different because Roth distributions are tax-free.

Because Roth IRA owners never have to take RMDs from their own accounts during their lifetime, every Roth IRA owner is treated as if they died "before their RBD." That means inherited Roth IRA beneficiaries are always on Path 1: no annual RMDs required, just empty the account by year 10.

The optimal strategy for most inherited Roth IRA beneficiaries is to take nothing for nine years, let the account compound tax-free, then withdraw the entire balance in year 10 as a tax-free distribution. A $300,000 inherited Roth growing at 7% per year becomes approximately $589,000 by year 10. All tax-free.

There is a 5-year holding period requirement for the Roth itself to be qualified. If your parent opened the Roth more than 5 years before death, all distributions are tax-free. If less, the earnings portion may be subject to income tax until the 5-year mark is hit. The contribution basis is always tax-free.

What you should actually do in 2026 if you just inherited an IRA

Before you take any distribution, before you call your parent's advisor, before you do anything irreversible, do these five things in order.

1. Confirm the date of death. This sets your 10-year clock. The clock does not start the day you find out about the inheritance. It starts the calendar year of death. A death in November 2024 gives you until December 31, 2034. A death in January 2025 gives you until December 31, 2035. One month difference, one full year of distribution flexibility.
2. Confirm whether the decedent had started RMDs. Ask the IRA custodian for the year-of-death RMD status. This determines whether you are on Path 1 or Path 2. Wrong answer here is a $7,500+ mistake every year for nine years.
3. Open a separate inherited IRA in your own name. The account must be retitled as "[Your Name] beneficiary of [Decedent Name]." Do not, under any circumstances, let the executor liquidate the original IRA and distribute cash to you. This is the single most expensive mistake people make. I have written a separate article on this exact disaster.
4. Take any year-of-death RMD if applicable. If the decedent had a 2026 RMD obligation that they had not satisfied before they died, you as the beneficiary are responsible for taking that RMD by December 31, 2026. Failure triggers the 25% excise tax.
5. Build a 10-year distribution plan that minimizes lifetime tax, not annual tax. Most people instinctively take the minimum each year and end up with a massive balloon distribution in year 10 that pushes them into a higher tax bracket. The right strategy depends on your current and projected income, your spouse's income if applicable, the size of the inherited account, and your state of residence. This is the highest-value financial planning conversation you will have in the next decade.

Three mistakes that cost real money in 2026

I work with families navigating inherited IRAs every year. The same three mistakes show up over and over, and each one is preventable.

Mistake 1: Liquidating the IRA instead of splitting it. When multiple siblings inherit, the executor sometimes liquidates the entire account and distributes cash. This triggers immediate full taxation on the entire balance in a single year. A $3 million IRA split among three siblings should become three separate $1 million inherited IRAs, each with its own 10-year clock. Liquidating instead can cost the family more than $1 million in unnecessary taxes.

Mistake 2: Waiting until year 10 when annual RMDs were required. If your parent died after their RBD and you ignore the year 1-9 annual RMD requirement, you face a 25% excise tax on every missed RMD. A beneficiary with a $500,000 inherited IRA who misses a $30,000 annual RMD owes $7,500 in penalty plus the back-owed RMD plus the income tax on the eventual distribution.

Mistake 3: Taking the minimum and getting hit by the year-10 balloon. The 10-year rule is a deadline, not a recommendation to wait. A $750,000 inherited IRA growing at 6% with only minimum distributions in years 1-9 still has roughly $700,000 sitting in the account at the start of year 10. Forced to withdraw all of it that year, the beneficiary lands in the 37% federal bracket plus state tax. A planned withdrawal strategy spreading taxable income across the full 10 years often saves $100,000 or more in lifetime taxes.

Bottom line for inherited IRAs in 2026

The 10-year rule is not flexible. There is no extension, no exception for hardship, no negotiation with the IRS. The clock starts the year of death and ends 10 years later, period. Within that window, you have real strategic flexibility, but only if you understand which path you are on and plan accordingly.

If you just inherited an IRA in 2026 and the balance is over $250,000, the cost of getting this wrong is significantly higher than the cost of a fee-only fiduciary advisor to plan it correctly. The math is straightforward. A $500,000 inherited IRA, withdrawn poorly, can cost an extra $75,000 to $150,000 in unnecessary lifetime taxes. A planning engagement to map out the 10-year costs a fraction of that.
