Inherit a Father’s $250,000 IRA at 60 and Try to Convert It to a Roth to Stop the Ten-Year Clock, and the Custodian Says No

Picture a 60-year-old who inherits their father’s $250,000 traditional IRA and asks the custodian for a Roth conversion. The idea is to let the money grow tax-free and sidestep the ten-year withdrawal deadline. The custodian says no, and that’s the right call. It’s a sensible idea, but the law doesn’t allow it. Here are the rules that actually apply, plus the one path that could have worked if the money had been held somewhere else.

Why Every Custodian Gives the Same Answer

An inherited IRA is the account an heir receives when an IRA owner dies. Paying tax today on pre-tax money through a Roth conversion means later withdrawals come out tax-free. According to an IRA analyst at Ed Slott and Company, writing in a September 10, 2026 mailbag, non-spouse beneficiaries cannot convert an inherited traditional IRA to an inherited Roth IRA. That limit comes from the tax rules themselves, so moving the account to another firm won’t change the answer.

An Employer Plan Opens a Window

The picture changes if the father’s money is still sitting in a 401(k) or a similar workplace plan. The tax code’s Section 402(c)(11) allows a direct rollover of a deceased worker’s plan balance into an inherited IRA set up for a non-spouse beneficiary. Long-standing IRS guidance allows that destination to be an inherited Roth IRA, with the converted amount taxed in the year it moves, and the money must go straight from the plan via a trustee-to-trustee transfer. Once the balance lands in an inherited traditional IRA, the window is closed for good.

How the Clock Runs When Dad Was Already Taking RMDs

The smallest amount the IRS requires someone to withdraw each year is called a required minimum distribution, or RMD. Most non-spouse heirs who inherited after January 1, 2020, have to empty the account within 10 years of the owner’s death. If the owner died on or after his required beginning date, the heir must also take annual RMDs in years 1 through 9, based on the heir’s life expectancy.

A father with a 60-year-old child had almost certainly passed that date, so annual withdrawals apply here. The IRS waived penalties for missed annual RMDs from 2020 to 2024 while it settled the rules, and penalties have applied since 2025. Older articles that say no annual withdrawals are needed were written during that relief period.

Exceptions That Could Stop the Clock

Eligible designated beneficiaries aren’t bound by the ten-year rule. They include a surviving spouse, minor children, and individuals no more than ten years younger than the IRA owner and/or with a disability. A chronically ill beneficiary can also qualify. A minor child can take life-expectancy payments until age 21, and the ten-year timer starts then. For a 60-year-old heir, check the age test. If a father or stepfather was born within ten years of the beneficiary, the heir becomes eligible, swapping the ten-year schedule for lifetime withdrawals.

Timing Is the Only Lever Left

Since conversion isn’t an option, the tax bill depends on when the money comes out. In 2026, joint filers pay 12% on taxable income up to $100,800 and 22% above that level, after a $32,200 standard deduction.

Consider a married heir with $150,000 of taxable income who works four more years and then retires on $50,000 of taxable income. To keep the example simple, it ignores investment growth. If the. heir takes level withdrawals of $25,000 a year, the federal tax comes to roughly $40,000, because the four working years land in the higher bracket. A shaped schedule works differently: it takes a minimum of $10,000 a year while the heir is still working, then about $35,000 a year after retirement.

Under that schedule, retirement income tops out near $85,000, which stays in the 12% bracket. Total tax drops to about $34,000, saving roughly $6,000. Putting off everything until year ten would cost more, since a single large withdrawal would push you into higher brackets.

Medicare, Social Security and Charity Rules Also Apply

Medicare Part B premiums increase once modified adjusted gross income exceeds $109,000 for individual filers or $218,000 for joint filers. The first surcharge is $81.20 a month, charged to each enrolled person. Medicare sets premiums from the tax return filed two years earlier, so one heavy withdrawal year shows up in premiums later.

Social Security benefits become taxable once combined income tops $25,000 filing individually or $32,000 filing jointly. An heir who has reached age 70 ½ can make qualified charitable distributions from an inherited IRA, routing funds that would otherwise be taxed directly to a charity.

Mistakes That Make It Worse

Inherited money has to stay separate from the heir’s own IRA. The account is set up as an inherited IRA, usually titled in the father’s name and marked deceased, for the heir’s benefit. IRS Publication 590-B allows an heir to combine inherited Roth accounts only if the beneficiary inherited the other Roth IRA from the same decedent. This also applies to a surviving spouse. Missing a required annual withdrawal triggers a 25% excise tax, which drops to 10% if you correct the shortfall within two years. That penalty is one of several IRS rules that quietly drain retirement accounts, and we charted the rest in a free tax trap map.

Ask Where the Money Sits Before Moving It

Before signing any transfer form, an heir should find out whether the money is still in an employer plan and, if so, whether a direct rollover to an inherited Roth IRA is still possible, with the tax due that year. If the money is already in an inherited traditional IRA, the only remaining decision is how to spread withdrawals across the ten-year window. The savings come from moving more into the years after the paychecks stop.
