Understanding the IRS 10-Year Rule Mechanics
Key distinctions finalized in Treasury Decision 10001 (July 2024) affecting all inherited IRA accounts.
The "At Least As Rapidly" Rule
If the decedent died on or after their Required Beginning Date (RBD), the beneficiary cannot simply wait 10 years to withdraw. The IRS mandates annual RMDs in Years 1 through 9 based on the beneficiary's single life expectancy.
The "Minus 1" Factor Reduction
Under Treas. Reg. § 1.401(a)(9)-5, the initial divisor is taken from IRS Table I in Year 1. In subsequent years, the divisor is reduced by 1.0 each year rather than re-looking up the factor at the new age.
Eligible Beneficiary Exceptions
Surviving spouses, minor children of the deceased (until age 21), disabled individuals, chronically ill individuals, and beneficiaries not more than 10 years younger than the deceased qualify as "Eligible Designated Beneficiaries" and may stretch over lifetime.
Federal Income Tax Brackets (Why Smoothing Matters)
Single & Married Filing Jointly Brackets| Tax Rate | Single Filers (Taxable Income) | Married Filing Jointly (Taxable Income) | Planning Takeaway |
|---|---|---|---|
| 10% / 12% | Up to $47,150 | Up to $94,300 | Ideal bracket to fill with annual withdrawals |
| 22% / 24% | $47,151 to $201,050 | $94,301 to $402,100 | Common baseline for middle & upper-middle earners |
| 32% / 35% / 37% | $201,051 and higher | $402,101 and higher | Balloon lump-sum cliff to strictly avoid |
Frequently Asked Questions
Essential rules for navigating inherited IRA distribution schedules.
What is the 10-year rule for an Inherited IRA under SECURE 2.0? ▼
Under the SECURE Act (and final IRS regulations issued in July 2024), most non-spouse designated beneficiaries must completely empty the inherited IRA account by December 31 of the 10th year following the original owner's death.
Are annual RMDs mandatory during Years 1 through 9? ▼
Yes, IF the original owner died on or after their Required Beginning Date (RBD, age 72 or 73). Under the IRS "at least as rapidly" rule, the beneficiary must take annual RMDs in Years 1–9 using their IRS Single Life Expectancy factor, and withdraw all remaining funds by Year 10. If the owner died before their RBD, annual RMDs in Years 1–9 are not required, but the 10-year total distribution rule still applies.
What is the tax trap of waiting until Year 10 to withdraw everything? ▼
If you take zero or minimum withdrawals and empty the entire account in Year 10, the massive lump sum is stacked on top of your ordinary income for that year. This can catapult you into the highest 37% federal tax bracket, trigger the 3.8% Net Investment Income Tax (NIIT), increase Medicare IRMAA surcharges, and cause you to lose tens of thousands of dollars to avoidable taxes.
How does tax bracket smoothing save money on inherited IRAs? ▼
Tax smoothing spreads withdrawals evenly across all 10 years, filling up lower tax brackets (such as the 12%, 22%, or 24% brackets) each year rather than spilling into the 32%, 35%, or 37% brackets in Year 10. Our calculator forecasts tax savings often exceeding $30,000 to $90,000.
Does the 10-year rule apply to Inherited Roth IRAs? ▼
Yes, inherited Roth IRAs are subject to the 10-year rule and must be emptied by Year 10. However, because the original owner never has an RMD requirement during life, beneficiaries are NEVER required to take annual RMDs in Years 1–9. Furthermore, all qualified withdrawals from an inherited Roth IRA are 100% tax-free, making it optimal to leave the funds growing tax-free until Year 10.
