Heirs Discover Tax Balloon Hiding in a $900,000 Inherited IRA
Most heirs who inherit a large traditional IRA focus on minimizing each year's required distribution, never realizing that strategy quietly builds a tax balloon set to burst in year 10 at the worst possible moment.

You inherited a parent’s traditional IRA worth roughly $900,000. You are in your late 40s or 50s, still working, earning well, and the account is not money you need to touch. So you take the smallest legally required distribution each year, let the balance keep compounding, and plan to “deal with it later.” Later is year 10, and the tax bill that arrives can reshape a household’s finances.
This scenario has become one of the most common estate-planning traps since the SECURE Act rewrote the rules for non-spouse beneficiaries. Financial planners describe versions of it constantly. An heir in peak earning years inherits a large pre-tax account, focuses on the annual required minimum, and never models what year 10 actually looks like.
Why the 10-Year Rule Changes Everything
For most non-spouse beneficiaries who inherited an IRA after 2019, the entire account must be emptied by Dec. 31 of the tenth year after the original owner’s death. If the original owner had already started taking required minimum distributions, the heir also must take annual RMDs in years one through nine based on their own life expectancy. Those annual RMDs are modest. A 50-year-old heir with a $900,000 balance pulls out something in the low tens of thousands per year.
Meanwhile, the account keeps compounding. Assume a mid-single-digit return, roughly in line with a portfolio anchored to today’s 4.68% 10-year Treasury yield plus an equity sleeve. After nine years of minimum-only withdrawals, the balance can easily still sit near $700,000. Every dollar of that remainder must come out in year 10 as ordinary income, stacked on top of the heir’s salary.
The Balloon in 2026 Brackets
For 2026, the IRS set the married-filing-jointly brackets so that the 32% rate starts at $403,550, the 35% rate at $512,450, and the top 37% rate kicks in above $768,700. The standard deduction is $32,200.
Picture a dual-income couple earning $350,000 in salary. Their taxable income already reaches into the 24% bracket. Drop a $700,000 forced distribution on top and almost the entire balloon lands in the 32%, 35%, and 37% brackets. The last several hundred thousand dollars are taxed at the highest marginal rate in the code. That is how heirs end up paying $80,000 to $100,000 more in federal tax than they would have with a smoother plan. And don’t forget that state income tax adds another layer in high-tax states.
Two Paths, Side by Side
Heirs have two main choices.
- Minimum-only, then balloon. Take the life-expectancy RMD in years one through nine. Year 10 forces out roughly $700,000 in a single tax year, most of it taxed at 32% to 37%. This is the most expensive option for almost every heir in peak earning years.
- Engineered bracket-fill withdrawals. Starting in year one, pull out enough each year to fill your current bracket without spilling into the next one. For the couple above, that might mean drawing $60,000 to $90,000 annually so taxable income stops just under the $403,550 line where 32% begins. Nine years of disciplined draws leaves a far smaller residual for the year-10 sweep, and the blended tax rate on the whole inheritance can land near 24% instead of drifting into the mid-30s.
The second path is clearly better for most heirs still working. The only situation where minimum-only makes sense is an heir who expects a dramatic income drop inside the 10-year window, for example someone retiring in year four or five with no other large income sources. Even then, the smart move is usually a hybrid: small draws while working, larger draws once salary stops.
Withdrawn dollars do not have to be spent. Use them to fund your own Roth IRA contributions, backdoor Roth conversions of other pre-tax balances in low-income years, taxable brokerage investments, or a 529 for children. The inherited IRA is being drained on a fixed timer regardless. Redirecting the proceeds into accounts you control lets you convert a forced tax event into permanent tax diversification.
What to Do This Year
Pull the year-end balance of the inherited IRA and project it forward at a realistic growth rate to year 10. Then look at the 2026 bracket table and identify the ceiling you can fill without jumping a tier. Set that number as your annual withdrawal target and revisit it every January as your salary and the account balance move.
If the inherited balance is above roughly $500,000 and you are still working, a fee-only CPA or tax-focused planner will typically save several multiples of their fee by modeling the 10-year path in year one rather than year nine.
