The SECURE Act quietly replaced stretch IRA distributions with a 10-year deadline — and most heirs are bungling the timing in a way that spikes their tax bill by five figures.
The Law Changed and Most Heirs Have No Idea
Before 2020, inheriting an IRA was one of the greatest wealth-transfer tools in American tax law. A 30-year-old who inherited a $500,000 IRA from a parent could stretch small required minimum distributions over their entire life expectancy — sometimes 50+ years — letting most of the money compound tax-deferred for decades. The SECURE Act ended that. For anyone who inherited an IRA from an owner who died on or after January 1, 2020, the entire account must be drained within 10 years. No exceptions for most adult beneficiaries. The stretch IRA is gone, and most people still don't know it — which is exactly the kind of ignorance the IRS is happy to let you maintain.
The Misconception That's Costing Heirs the Most Money
The most dangerous thing most inherited IRA beneficiaries do is nothing. They assume the 10-year rule just means they have a long runway and that they'll deal with it later — then they wait until year 9 or 10 to make a move. Some even believe there's a smart strategy in waiting: let it compound longer, take it all at the end. That logic falls apart completely when you look at what a lump-sum withdrawal actually does to your tax return. Taking $400,000 in a single year doesn't just create a $400,000 tax problem — it can shove $350,000 of ordinary income into the top federal brackets while simultaneously triggering the 3.8% Net Investment Income Tax on other income, disqualifying you from education credits, and possibly affecting financial aid or Medicare premium calculations. The IRS doesn't warn you. It just processes your return.
The Math: What Bad Timing Actually Costs
Let's use a real example. You inherit a traditional IRA worth $400,000 at age 42. Your normal salary is $95,000, putting you solidly in the 22% federal bracket. Option A: You wait until year 10 and withdraw the full balance — let's say it's grown to $520,000 by then. That $520,000 added to your $95,000 salary creates $615,000 in taxable income. The marginal rate on most of that inherited IRA money hits 32% to 35%. Your federal tax bill on the IRA alone: roughly $160,000 to $175,000. Option B: You take $52,000 per year over 10 years. Added to your $95,000 salary, total income is $147,000 — comfortably in the 22% bracket for most of that distribution. Federal tax on the same $520,000 spread out: closer to $114,000. The difference is approximately $55,000 in federal taxes — paid unnecessarily — just from poor distribution timing. State income taxes make that gap even wider in high-tax states like California or New York.
The Spousal Exception Is Genuinely Powerful — Use It
Surviving spouses get far better treatment under the tax code and most don't fully exploit it. A spouse who inherits an IRA has two primary options: roll it into their own IRA and treat it as their own money (subject to their own RMD schedule), or keep it as an inherited IRA and take distributions based on their own life expectancy. The rollover strategy is usually superior for younger spouses who don't need the money yet — it resets the RMD clock to their own age-73 required start date and keeps the account compounding longer. But a spouse under 59½ who might need early access should consider keeping it as an inherited IRA first, since distributions from an inherited IRA avoid the 10% early withdrawal penalty. This is a sequencing decision worth sitting down with a tax advisor for — the numbers are too large to guess at.
The 10-Year Rule Gets Complicated When the Original Owner Was Already Taking RMDs
Here's a wrinkle that tripped up thousands of beneficiaries when IRS guidance finally clarified it: if the original IRA owner had already reached their required beginning date (age 73 for most people) and was already taking RMDs when they died, the beneficiary cannot simply ignore annual distributions for years 1-9. The IRS requires that non-spouse beneficiaries continue annual RMDs during the 10-year window — calculated based on the beneficiary's own life expectancy — AND still drain the account completely by year 10. This rule caught a huge number of heirs off guard in 2023 and 2024 when IRS guidance was finalized. If your inherited IRA came from someone already in RMD status, you have annual obligations, not just a 10-year deadline. Missing those annual RMDs triggers the 25% excise tax on the amount that should have been distributed.
What to Do Right Now — This Week
First, confirm whether your inherited IRA came from someone who died before or after January 1, 2020 — and whether they had reached their required beginning date. This determines your exact rule set. Second, pull your last three years of tax returns and estimate your projected income for the next 10 years. Look for years where income will be lower — a career transition, a sabbatical, a year between jobs — and front-load distributions in those years to stay in the 22% or 24% bracket rather than 32% or 35%. Third, if you inherited a Roth IRA, the 10-year rule still applies, but qualified distributions are tax-free — so you have more flexibility on timing since there's no ordinary income to manage. Fourth, consider the interaction with your own retirement account contributions: a year with a large inherited IRA distribution isn't a great year to also convert a traditional IRA to Roth, since both hit ordinary income simultaneously. Use our Retirement Calculator at /tools/calculators/retirement to model different distribution scenarios side by side before committing to a strategy.
The Roth Inherited IRA: Better Rules, Same Deadline
Inheriting a Roth IRA is genuinely better than inheriting a traditional IRA — but the 10-year rule still applies and most beneficiaries don't realize this. The good news: qualified distributions from an inherited Roth IRA are completely tax-free, so timing matters far less from a tax bracket standpoint. You can let it compound for all 10 years and pull everything in year 10 with zero federal income tax owed on the growth. The only meaningful risk is if the original account was opened less than five years before death — in that case, only the contributions come out tax-free; earnings may be taxable. For most inherited Roth IRAs, the practical advice is simple: let it run for as close to the full 10 years as possible, let compounding do its work tax-free, and withdraw at the end. It's one of the few times where waiting actually is the right call.
If you inherited an IRA after January 1, 2020, stop assuming you can let it sit untouched for a decade. Map out your income for the next 10 years right now and identify your two or three lowest-earning years — those are the windows to take larger distributions and stay in a lower bracket. Run the numbers with our Retirement Calculator at /tools/calculators/retirement to see exactly how distribution timing changes your after-tax outcome. Doing nothing is a choice that usually benefits the IRS, not you.

- →Waiting until year 10 to withdraw a $400,000 inherited IRA can cost $55,000+ more in federal taxes versus spreading distributions across lower-income years
- →If the original IRA owner had already started RMDs, you likely owe annual distributions during years 1-9 — not just a final 10-year deadline — missing them triggers a 25% excise tax

Frequently Asked Questions
What is the inherited IRA 10-year rule?
Under the SECURE Act of 2019, most non-spouse beneficiaries who inherit an IRA must fully withdraw all funds within 10 years of the original owner's death. There are no required annual distributions during years 1-9 — but the account must be at zero by December 31 of the 10th year. Failing to empty the account in time triggers a 25% excise tax on any remaining balance.
Who is exempt from the inherited IRA 10-year rule?
Eligible designated beneficiaries (EDBs) can still use the old stretch IRA rules. This group includes surviving spouses, minor children of the deceased (until they reach majority), disabled or chronically ill individuals, and beneficiaries not more than 10 years younger than the original owner. Everyone else — including adult children and most other heirs — falls under the 10-year rule.
Can I just wait until year 10 to withdraw everything from an inherited IRA?
Legally, yes — but financially, it's usually one of the worst strategies available. Pulling the entire balance in a single year often pushes you into the 32%, 35%, or even 37% federal bracket, erasing tens of thousands of dollars that could have been yours with better spacing. Strategic annual withdrawals in lower-income years can cut your effective tax rate on the same money by 10 to 20 percentage points.
