The 10-Year Rule Explained: How Inherited IRA Withdrawals Work After 2026
Time is money, especially when the IRS clocks are ticking.
Under the post‑SECURE and SECURE Act 2.0 distribution rules for Inherited IRAs, most non‑spouse designated beneficiaries must fully distribute the account by the end of the 10th year following the original owner’s death, and if the original owner died after their Required Beginning Date, annual RMDs are required in years 1 through 9 using the IRS Single Life Expectancy Table.
- No annual RMDs? Think again: if the original owner died after their Required Beginning Date, current IRS guidance requires you to calculate and take annual RMDs in years 1 through 9 using the Single Life Expectancy Table and still empty the inherited IRA by the end of year 10
- Compound Interest or Compounded Mistakes? Waiting until the last year could bump you into a higher tax bracket, leading to hefty taxes.

|---|---|---|
| Equal withdrawals over 10 years | $200,000 | $600,000 |
| No withdrawals until year 10 (lump sum) | $2,000,000 | $740,000 |
| Customized, tax‑efficient withdrawals | Varies by plan | $500,000 |
