The 10-Year Rule for Inherited IRAs: SECURE Act, RMDs, and Distribution Strategy

The Setting Every Community Up for Retirement Enhancement (SECURE) Act of 2019 ended the lifetime stretch IRA for most non-spouse beneficiaries. Under the new rules, non-spouse beneficiaries who inherit a retirement account after December 31, 2019 must distribute the entire balance within 10 years of the original owner's death. SECURE 2.0 (passed late 2022) added a wrinkle: in many cases, annual RMDs are required during those 10 years, not just by the deadline.

How the 10-year rule works

For a Traditional inherited IRA, the beneficiary is taxed at ordinary-income rates on every distribution. Front-loading distributions in early years can make sense if those years are low-income; back-loading can make sense if you expect to be in a lower bracket later. But everything must be out by December 31 of the year that includes the 10-year anniversary of the decedent's death.

For a Roth inherited IRA, distributions are tax-free assuming the original account was at least 5 years old. The 10-year rule still applies — you can't hold the inherited Roth indefinitely — but the tax pain is largely absent.

The annual-RMD requirement (post-SECURE 2.0)

For decedents who had already begun their own RMDs at the time of death, the inherited Traditional IRA beneficiary must take annual RMDs during years 1 through 9 of the 10-year window AND fully drain the balance by year 10. The IRS waived enforcement for 2021-2024 while the regulations were being finalized; the requirement applies starting tax year 2025.

For decedents who had not yet begun RMDs (typically those who died before age 73, the SECURE 2.0 RMD start age), no annual RMDs are required during years 1-9 — only the year-10 distribution deadline.

Distribution strategy: front-load, back-load, or smooth

Three patterns dominate planning conversations:

Smooth distribution: take roughly 1/10th of the balance each year. Simplest; spreads tax across 10 years; works well if your tax bracket is stable.

Front-load during low-income years: if you're currently in a low bracket (early career, sabbatical, recent retirement before SS), take more in those years and less later. Especially useful for younger beneficiaries who anticipate higher future earnings.

Back-load if low-income years are coming: if you're currently in a high bracket but plan to retire within the 10-year window, distributions taken in retirement years (before 73 RMDs kick in on your own balance) may be cheaper.

Tax-bracket awareness is everything

Inherited IRA distributions stack on top of your other ordinary income. A $200K Traditional inherited IRA distributed evenly is $20K/year — likely staying in your existing bracket. The same $200K distributed in year 10 alone is a $200K bracket spike, potentially pushing you into 32% or 35% federal rates plus state and IRMAA Medicare surcharge implications.

Always model expected total income across the 10-year window before deciding the distribution pattern. Roth conversions of your own pre-tax balances during the same period — to manage tax efficiency holistically — are worth modeling concurrently.

Action items

If you've recently inherited an IRA, four immediate steps:

(1) Confirm the decedent's death date and original-owner age — these determine which version of the rules applies. (2) Re-title the account as an Inherited IRA at your custodian; do not roll it into your own IRA. (3) Calculate the 10-year deadline and any applicable annual RMD. (4) Engage a CPA to model distribution timing against your full tax picture; the math is non-trivial and the dollar stakes are large.
