Inherited IRA Rules in 2026: What the SECURE Act Changed and What It Costs You

You spent decades building a tax-deferred IRA. What happens to it after you die is now governed by rules that most families, and many advisors, still misread. If your beneficiaries are your adult children or other non-spouse heirs, the SECURE Act changes are not just procedural. They can cost your family tens of thousands of dollars in unnecessary taxes.

The 10-Year Rule Is Not What It Sounds Like

The headline change from the SECURE Act of 2019 was the elimination of the "stretch IRA" for most non-spouse beneficiaries. Under the old rules, an adult child could take distributions over their own lifetime, spreading the tax burden across decades. Now, a non-eligible designated beneficiary (think: adult children, most grandchildren, non-spouse partners) must fully empty the account within ten years of the owner's death.

That sounds manageable. The trap is what the IRS clarified in 2022 and fully enforced starting in 2025: if you, the original owner, had already begun taking required minimum distributions, your heirs cannot simply wait and take a lump sum in year ten. They must take annual RMDs in years one through nine, then clear the remainder by December 31 of year ten.

Ignore those annual distributions and the penalty is 25% of the amount that should have been withdrawn.

What This Looks Like in Real Dollars

Consider two scenarios.

The $500,000 inherited IRA. Your daughter inherits this at 45. Her salary already puts her in the 22% bracket. The IRS-calculated RMD in year one might be around $26,000. That amount alone stays within her bracket. But in year ten, if she has been taking only the minimum, the remaining balance could be $350,000 or more, all forced out in a single year. That income spike can push her well into the 32% or 35% bracket for that year.

The $2 million inherited IRA. The math compounds painfully. Annual RMDs in the early years may run $100,000 to $130,000 on top of her existing income. She may never escape the 32% bracket during the entire ten-year window. A poorly sequenced distribution strategy on a $2 million inherited balance can easily generate $200,000 or more in excess taxes compared to a deliberate, bracket-aware plan.

The Harvest stage of a well-built plan, described in the Sporos Doctrine, exists precisely for this kind of sequencing work. The goal is not just getting money out. It is getting money out at the lowest possible marginal rate, year by year.

What to Do This Week

If you have a significant IRA balance and adult children as beneficiaries, pull out your beneficiary designations and look at two things: who is named, and whether a trust or other structure might give your heirs more distribution flexibility. Then ask your advisor to model the ten-year RMD schedule under different scenarios, specifically what brackets your heirs land in each year given their own expected income.

This is not estate planning for the ultra-wealthy. A $600,000 IRA passed to a working professional can create a bracket problem that a little advance planning eliminates entirely.
