Inherited IRA Distribution Rules Under the SECURE Act: The 10-Year Depletion Explained

Before the SECURE Act took effect on January 1, 2020, a non-spouse beneficiary who inherited an IRA could stretch distributions over their own life expectancy — potentially decades of tax-deferred growth. A 35-year-old inheriting a $500,000 IRA could take small annual distributions for nearly 50 years.

That strategy is gone for most beneficiaries. The SECURE Act replaced the stretch with a mandatory 10-year depletion rule, and SECURE Act 2.0 added penalties and clarifications that are now fully in force.

The 10-Year Rule: Mandatory Full Depletion

Non-spouse beneficiaries who do not qualify as eligible designated beneficiaries (EDBs) must withdraw the entire inherited IRA balance by December 31 of the tenth year after the original owner's death.

The critical nuance: if the original account holder had already reached their required beginning date (currently age 73), the beneficiary must also take annual distributions during the 10-year window. This is the "ghost rule" — so named because the original owner's RMD schedule continues to haunt the account even after death.

If the original owner died before reaching their required beginning date, the beneficiary has more flexibility. They must still empty the account by year ten, but they can choose how to distribute the balance across those years. Some beneficiaries take nothing for nine years and empty the account in year ten. Others spread distributions evenly.

The Ghost Rule in Practice

The ghost rule catches advisors and beneficiaries off guard because its logic is counterintuitive. The original owner was required to take annual distributions. They died. The account now belongs to someone else. But the annual distribution requirement persists.

For a designated beneficiary subject to annual RMDs because the owner died on or after the required beginning date, the RMD generally uses the longer of the beneficiary's single life expectancy and the owner's life expectancy. If the beneficiary's factor controls, it is set using the beneficiary's age in the year after death and reduced by one each subsequent year.

This means the annual ghost-rule RMDs are typically small relative to the total account balance — but they are mandatory. Missing one can trigger a 25% excise tax on the shortfall amount under SECURE Act 2.0 (reduced from the previous 50% penalty, and further reducible to 10% if corrected within the correction window, generally two years). The IRS may waive some or all of the tax for a reasonable error when reasonable steps are taken to remedy it.

Eligible Designated Beneficiaries: Who Still Gets the Stretch

Five categories of beneficiaries are exempt from the 10-year rule and can still stretch distributions over their own life expectancy:

Surviving spouses have the most options. They can treat the IRA as their own (spousal rollover), remain as beneficiary and take distributions based on either the deceased's or their own age, or take a lump sum.

Minor children of the account holder — not grandchildren, nieces, or nephews. For these federal distribution rules, the child reaches majority at age 21, at which point the 10-year clock starts.

Disabled individuals meeting the IRC Section 72(m)(7) definition, which requires a physical or mental condition that prevents substantial gainful activity and is expected to be of long or indefinite duration.

Chronically ill individuals as certified by a licensed healthcare provider, meaning they are unable to perform at least two activities of daily living for at least 90 days or require substantial supervision due to cognitive impairment.

Beneficiaries not more than 10 years younger than the deceased — a category that primarily captures siblings, partners, or friends close in age.

Spousal Rollover: The Most Powerful Option

A surviving spouse who inherits an IRA may be able to roll it into their own IRA, effectively becoming the owner. This changes the distribution rules:

• RMDs follow the surviving spouse's own age and the Uniform Lifetime Table
• The surviving spouse can name their own beneficiaries
• The account continues to grow tax-deferred until the spouse's own required beginning date

A spousal rollover can be advantageous for a surviving spouse who does not need immediate access to the funds, but the choice depends on age, RMD timing, tax situation, and access needs. A surviving spouse under age 59½ who needs distributions may avoid the 10% early distribution penalty by keeping the account as an inherited IRA rather than rolling it into their own IRA.

Planning Across the 10-Year Window

For non-spouse beneficiaries locked into the 10-year rule, the distribution strategy should be driven by tax bracket management, not arbitrary timing.

If a beneficiary's income will be relatively stable over the decade, spreading distributions may avoid pushing as much income into higher marginal brackets. If income will vary — perhaps the beneficiary plans to retire in year four — taking more in projected lower-income years and less in higher-income years may reduce the total tax bill, subject to annual RMDs and the 10-year deadline.

Ignoring the account for nine years and taking a lump sum in year ten can push some of the distribution into a higher tax bracket. Whether spreading a $500,000 distribution over ten years keeps the beneficiary in a lower bracket depends on filing status, other income, and the tax rates in effect for each year.

This distribution planning — integrating the inherited IRA with the beneficiary's overall tax situation across the full 10-year window — is the kind of proactive work that justifies a financial advisor's involvement and demonstrates concrete value to newly inherited clients. The Financial Advisor's Deceased Client Guide includes an inherited IRA distribution planning worksheet that maps out the tax projections year by year.
