How Inherited IRA Rules Work After the SECURE Acts

Millions of Americans Are Making Costly Mistakes With Inherited IRAs

The SECURE Act of 2019 and SECURE 2.0 Act of 2022 fundamentally changed the rules for inherited IRAs, eliminating the popular stretch IRA strategy for most non-spouse beneficiaries and creating a new distribution regime with significant tax implications. Despite these changes taking effect January 1, 2020, the IRS noted widespread confusion and noncompliance, ultimately waiving penalties for missed distributions through 2024 while finalizing regulations. A 2024 Fidelity survey found that 40% of inheritors of retirement accounts did not understand the applicable distribution rules. The stakes are high: failing to take required distributions triggers a 25% excise tax penalty on the amount that should have been distributed.

Who Benefits: The Eligible Designated Beneficiary Categories

Under the SECURE Act framework, the first critical determination is whether the beneficiary qualifies as an Eligible Designated Beneficiary (EDB). EDBs receive more favorable treatment than general beneficiaries.

The 10-Year Rule: What It Requires

Most non-spouse individual beneficiaries — typically adult children and other relatives of the original IRA owner — are subject to the 10-year rule. This requires that the entire inherited IRA account be fully distributed within 10 years of the original owner's death. Under IRS final regulations released in 2024, if the original owner had already begun required minimum distributions (RMDs), the beneficiary must take annual RMDs in years 1–9 based on their own life expectancy, and distribute the remaining balance in year 10.

If the original owner had NOT yet begun RMDs (died before their required beginning date), the beneficiary must only ensure full account distribution by the end of year 10 — with no annual distribution requirement in the interim years.

Tax Planning Within the 10-Year Rule

The 10-year rule creates a significant tax planning opportunity. Unlike mandatory equal annual distributions, you have discretion over how to spread withdrawals across the 10-year window. Strategic distribution timing can dramatically reduce total tax burden.

• Front-load in low-income years: If you are in a low tax bracket for the first few years (career transition, early retirement), taking larger distributions early maximizes lower-bracket space
• Spread to avoid bracket creep: Adding large inherited IRA distributions to regular income can push you into higher brackets. Spreading distributions over 10 years keeps annual taxable income lower
• Convert simultaneously: If you are doing Roth conversions anyway, inherited IRA withdrawals in the same year count against the same brackets — coordinate these intentionally
• Consider Roth inherited IRAs separately: Inherited Roth IRAs are also subject to the 10-year rule, but distributions are generally tax-free since the original owner already paid taxes on contributions

The Surviving Spouse Advantage

Spouses have by far the most flexibility with inherited IRAs. Their options are more varied and more favorable than any other beneficiary category.

A key advantage of maintaining an inherited IRA (rather than rolling to own IRA) for surviving spouses who are significantly younger: if the surviving spouse needs to access funds before age 59½, inherited IRA distributions are not subject to the 10% early withdrawal penalty that applies to distributions from the spouse's own IRA.

Inherited Roth IRA Rules

Inherited Roth IRAs are also subject to the 10-year rule for non-EDB beneficiaries. However, since Roth IRAs do not have lifetime RMDs, the distribution rule applies differently: if the original owner died before their Roth RMD age (which is effectively never, since Roth IRAs have no lifetime RMDs), the 10-year rule applies with no annual distribution requirement — beneficiaries can take nothing for 9 years and the full balance in year 10. All distributions from an inherited Roth IRA are tax-free provided the original Roth has been open for at least five years (the five-year holding period test). This makes inherited Roth IRAs more valuable and more tax-planning-friendly than inherited traditional IRAs.

Common Mistakes and How to Avoid Them

• Missing year 1 RMDs: For beneficiaries of owners who had begun RMDs, the first required distribution from the inherited IRA must be taken in the year of death (if the original owner had not yet taken it), or in the beneficiary's first year — missing this triggers a 25% penalty
• Not updating beneficiary designations: Your IRA beneficiary designation supersedes your will — an ex-spouse named as beneficiary 20 years ago will inherit if you do not update the form
• Assuming non-deductible IRA basis: If the original owner made non-deductible contributions, a portion of each distribution is tax-free; track this with Form 8606
• Treating inherited IRA as own IRA: A non-spouse beneficiary who rolls funds into their own IRA commits a prohibited transaction — the money becomes fully taxable in the year of the error
