Why a 74-Year-Old Widow May Want to Avoid Rolling Her Late Husband’s $1 Million IRA Into Her Own Account

A custodian’s claim form can make the simplest option look appealing for a 74-year-old widow, but one checked box could trigger years of required withdrawals, higher Medicare premiums, and taxes that her late husband’s birthday would otherwise have postponed.

Take this example: a 74-year-old widow’s husband dies at 68, and she becomes the sole beneficiary of his $1 million traditional IRA. The custodian’s spousal claim form gives her the option to move the money into an IRA in her own name, which may seem like the cleanest choice.

For her, though, it is the expensive one. Because her husband was younger and died before required minimum distributions (RMDs) had begun, the tax code allows her to leave the account untouched until the year he would have turned 73. If she elects the rollover, the account switches to her own RMD timetable, which has already been underway for years.

Her Husband’s Birth Year Can Determine When Withdrawals Begin

The governing rule is Section 401(a)(9)(B)(iv) of the Internal Revenue Code, expanded by the SECURE 2.0 Act of 2022. When a surviving spouse inherits as beneficiary and chooses this treatment, required distributions “shall not be earlier than the date on which the employee would have attained the applicable age,” and the code treats her “as if the surviving spouse were the employee.”

In this case, her husband would have reached 73 in 2031, so no required withdrawal is due until then. She may still withdraw any amount at any time. IRS Publication 590-B says a spouse has three choices: treat the IRA as her own, roll it into her own IRA, or “treat yourself as the beneficiary rather than treating the IRA as your own.”

Rolling It Over at 74 Would Restart RMDs Immediately

Once the $1 million becomes hers, it follows her own schedule. Since she is already past the starting age, the account would fall into her next RMD cycle. Under the IRS Uniform Lifetime Table, the prior year-end balance is divided by 24.6 at age 75. The table below assumes she rolls the money into her existing IRA and that investment growth roughly offsets withdrawals, keeping the balance near $1 million:

The two paths converge in 2031, because the spousal election treats her as the original owner at her own age. The benefit of staying on the beneficiary schedule is that roughly $172,000 in forced income would remain off her tax return during the four-year gap.

Single-Filer Rules Make Forced Income More Expensive

She may file jointly for the year her husband dies, but from the following year forward she would file as a single taxpayer. For that filing status, the Medicare IRMAA surcharge begins above $109,000, compared with $218,000 for married couples filing jointly.

If her Social Security and pension generate $80,000 of modified adjusted gross income, the $40,650 RMD from the rollover would lift her 2027 income to about $120,650. Medicare uses a two-year lookback, so that 2027 income would determine her 2029 premium.

At current rates, Part B would increase from $202.90 to $284.10 per month, or about $974 more a year, and the Part D surcharge would add another $14.50 a month. IRMAA functions like a cliff: crossing a threshold by even $1 triggers the full higher tier. The thresholds change each year, so the 2029 limits will differ. Every RMD dollar is also taxed as ordinary income at her highest marginal rate.

A Single Checkbox Can Lock In the Rollover

Transferring the money into her own IRA is often the default, and it is usually the correct move for a widow who is younger than her late husband because it delays RMDs until her own age 73. For an older widow, however, it gives up the postponement.

The IRS can also effectively make the choice for her. Under Publication 590-B, the account is treated as hers if “contributions (including rollover contributions) are made to the inherited IRA” or if she misses an RMD she owes as a beneficiary. Combining her own IRA money with his account can therefore end the beneficiary treatment.

Three Steps That Preserve His Withdrawal Schedule

1. Title it as an inherited IRA. She should select spouse-beneficiary status on the claim form and keep her own IRA assets in a separate account.
2. Confirm the election and record the date. She should make sure the custodian’s records show she is being treated as the original owner, then note the year he would have turned 73. Missing an RMD can trigger a 25% excise tax on the shortfall under Section 4974(a).
3. Keep the rollover option open. Publication 590-B allows a spouse to roll a distribution into her own IRA within 60 days “as long as the distribution isn’t a required distribution.” She can wait and decide later.

The best choice depends on her age difference, income and estate plans, so it is worth reviewing the numbers with a financial professional before signing the custodian’s form.
