Inherited IRA and RMD Rules After Spouse Dies

The IRA Decision That Can't Wait

When a spouse dies, their IRA doesn't just pass to the survivor automatically. The surviving spouse faces a choice about how to handle the inherited account — and that choice has tax consequences that compound every year for the rest of their life.

This decision interacts directly with the widow's tax penalty — the compression of tax brackets, standard deduction, and income thresholds that hits when a surviving spouse transitions from married filing jointly to single. Getting the IRA handling right can reduce the tax impact by thousands of dollars annually. Getting it wrong accelerates the penalty.

Surviving Spouse Options for an Inherited IRA

A surviving spouse has options that no other beneficiary gets. Understanding all three is essential before making a move.

Option 1: Spousal Rollover

The surviving spouse rolls the deceased's IRA into their own IRA (or into a new IRA in their own name). This is the most common choice, and it carries significant advantages:

• RMDs follow the survivor's own schedule. Once the survivor reaches the applicable required beginning age, RMDs follow the rules for their own IRA. The age is 73 for people born in 1951–1959 and 75 for those born in 1960 or later; earlier birth cohorts were subject to earlier starting ages. The applicable IRS table depends on the survivor's circumstances. If the survivor is younger than their applicable age, no owner RMD is required yet — the money continues growing tax-deferred.
• New beneficiary designation. The surviving spouse names their own beneficiaries on the rolled-over IRA, controlling the next generation of inheritance.
• Full contribution rights. The surviving spouse can continue making IRA contributions to the account (if eligible).

When to use it: The survivor is 73 or older and wants to delay distributions as long as possible, or the survivor is under 73 and doesn't need the funds yet.

Option 2: Remain as Beneficiary (Inherited IRA)

The surviving spouse keeps the account titled as an inherited IRA rather than rolling it into their own. This option makes sense in specific circumstances:

• The survivor is under 59½. Distributions from an inherited IRA are not subject to the 10% early withdrawal penalty, regardless of the beneficiary's age. If the surviving spouse needs access to funds before 59½, this avoids the penalty that a rollover IRA would trigger.
• RMDs may start sooner. The schedule depends on whether the deceased spouse had reached their required beginning date. If they had, a surviving spouse who remains a beneficiary generally bases RMDs on the longer of the survivor's or deceased owner's life expectancy. If they had not, a sole-beneficiary spouse can generally use the survivor's life expectancy or elect the 10-year rule. Confirm the applicable schedule with the custodian before taking withdrawals.

When to use it: The survivor is under 59½ and may need penalty-free access to the funds.

Option 3: Disclaim (Rare)

The surviving spouse can make a qualified disclaimer within nine months of the death, before accepting the benefit. The account then passes under its existing beneficiary terms; the spouse cannot use a disclaimer to choose a new recipient. This makes sense only in unusual estate planning scenarios where the surviving spouse doesn't need the funds and wants to accelerate the transfer to the next generation.

RMD Changes After a Spouse's Death

Required minimum distributions are where the tax impact becomes concrete.

Year of death. If the deceased spouse had already started RMDs and hadn't taken their full distribution for the year of death, the surviving spouse (or the estate) must take the remaining distribution by December 31 of that year. This is non-negotiable and frequently missed — the penalty for a missed RMD is 25% of the amount that should have been withdrawn (reduced to 10% if corrected within two years).

Following years — rollover path. If the survivor rolls the IRA into their own account, RMDs follow the survivor's applicable required beginning age and circumstances. The age is 73 for people born in 1951–1959 and 75 for those born in 1960 or later; earlier birth cohorts were subject to earlier starting ages. The applicable IRS table depends on the survivor's circumstances.

Following years — inherited IRA path. If the survivor keeps the inherited IRA, the schedule depends on when the deceased spouse reached their required beginning date. The surviving spouse's beneficiary RMDs generally use the survivor's life expectancy if the deceased died before that date, or the longer of the survivor's and deceased owner's life expectancies if the deceased died on or after it.

The Roth Conversion Opportunity

The year of death and the following year often create a narrow window where a Roth conversion is unusually advantageous.

Why it works: In the year of death, the surviving spouse can still file a joint return, which means wider tax brackets and a higher standard deduction. In the year or two following, before the full force of the widow's tax penalty kicks in, the survivor's taxable income may be temporarily lower — especially if they haven't yet started receiving the deceased's pension or if Social Security adjustments haven't taken effect.

If the survivor expects a lower marginal rate in this window than in future years as a single filer, converting traditional IRA funds to a Roth may reduce taxes over time. The conversion increases taxable income in that year; the converted funds then grow tax-free in the Roth and, in the survivor's own Roth IRA, are not subject to lifetime RMDs.

The math in practice: With $80,000 of taxable income in 2026, a joint filer is in the 12% marginal bracket; the 22% bracket begins over $100,800. A single filer with the same taxable income is in the 22% bracket, which begins over $50,400. Whether a Roth conversion reduces lifetime taxes depends on the amount converted, other income and deductions, and future income, so model the numbers across multiple years rather than assume a fixed conversion will save a particular amount.

Caution: A Roth conversion increases taxable income in the year of conversion, which can push the survivor above the Medicare IRMAA threshold ($109,000 for people filing individually in 2026). Medicare generally uses tax-return income from two years earlier, so a 2026 conversion can affect 2028 premiums. Run the numbers across multiple years, not just the conversion year.

The Year-of-Death Tax Return

The final joint return is a critical planning opportunity. The surviving spouse can file jointly for the year of death, claiming the married filing jointly standard deduction and bracket widths one last time. This return should include:

• The deceased's income through date of death
• The survivor's income for the full year
• Any RMDs taken or required
• Any Roth conversions executed during the year
• Capital gains or losses from inherited-asset sales (a basis adjustment to date-of-death value generally applies to many inherited assets, but exceptions and asset-specific rules matter)

After the year of death, the filing status changes to single — unless the survivor qualifies as a Qualifying Surviving Spouse (requires a dependent child), which extends the joint-width brackets for two additional years.

Don't Make This Decision Alone

The interaction between inherited IRA choices, RMD schedules, Roth conversion windows, and the widow's tax penalty is genuinely complex. A fee-only financial planner or CPA who specializes in retirement income planning can model the scenarios across a five- to ten-year horizon and identify the approach that minimizes lifetime tax liability.
