Required Minimum Distributions After Your Spouse Dies
Content is for informational purposes only and does not constitute tax or investment advice. RMD rules are fact-specific; work with a fee-only advisor before making rollover or withdrawal decisions.
- Inherited IRA RMDs may start immediately. If your spouse was already past their required beginning date, you may owe an RMD from the inherited account in the year of death — or by December 31 of the following year. How you handle the account determines the timing.
- Filing single roughly doubles your marginal rate on RMDs. A $40,000 RMD that stayed in the 22% bracket as a married couple may hit 22–24% as a single filer, on top of a lower standard deduction. The tax on the same dollar of withdrawal jumps.
- IRMAA thresholds are cut in half. The Medicare surcharge that starts at $218,000 for joint filers starts at $109,000 for single filers. Large RMDs can push you over it, adding $600–$7,000+/year in Medicare premiums.4
RMD ages under SECURE 2.0
Before anything else, establish your own RMD starting age. SECURE Act 2.0 changed the required beginning date depending on birth year:1
| Born in | Your RMD start age | First deadline |
|---|---|---|
| 1951–1959 | 73 | April 1 of the year after you turn 73 |
| 1960 or later | 75 | April 1 of the year after you turn 75 |
This matters because the choice you make with your spouse's inherited IRA — roll it over vs. keep it as inherited — determines when RMDs start on that money. More on that below.
The inherited IRA decision and RMD timing
As a surviving spouse, you have options no other beneficiary gets. The one with the biggest RMD impact is the spousal rollover: you can treat your spouse's IRA as your own, which resets the RMD clock to your RMD start age.
| What you do with the inherited IRA | RMDs start… | Penalty exception |
|---|---|---|
| Spousal rollover — roll to your own IRA | When you reach age 73 (or 75 if born 1960+) | 10% penalty applies before your age 59½ |
| Keep as inherited IRA (life-expectancy stretch) | Dec. 31 of year after death, or when deceased would have turned 73 | No 10% penalty at any age |
| SECURE 2.0 election (inherited 2024+) | When deceased would have reached their own RMD age | No 10% penalty in inherited account |
The full decision analysis — including the critical rule about not rolling over if you're under 59½ — is covered in Inherited IRA Rules for Surviving Spouses. Once you've made that decision, the RMD calculation below applies.
How to calculate your RMD
The formula is simple:
If you rolled your spouse's IRA into your own, add the balances together — all your traditional IRAs and rollover IRAs aggregate for RMD purposes. The life expectancy factor comes from the IRS Uniform Lifetime Table (Table III, IRS Publication 590-B):2
| Your age in 2026 | Life expectancy factor | RMD on $500,000 balance | RMD on $800,000 balance |
|---|---|---|---|
| 73 | 26.5 | $18,868 | $30,189 |
| 74 | 25.5 | $19,608 | $31,373 |
| 75 | 24.6 | $20,325 | $32,520 |
| 76 | 23.7 | $21,097 | $33,755 |
| 77 | 22.9 | $21,834 | $34,934 |
| 78 | 22.0 | $22,727 | $36,364 |
| 79 | 21.1 | $23,697 | $37,915 |
| 80 | 20.2 | $24,752 | $39,604 |
| 81 | 19.4 | $25,773 | $41,237 |
| 82 | 18.5 | $27,027 | $43,243 |
| 83 | 17.7 | $28,249 | $45,198 |
| 84 | 16.8 | $29,762 | $47,619 |
| 85 | 16.0 | $31,250 | $50,000 |
Important: If you kept an account as an inherited IRA (not rolled over), the RMD for that specific account uses the IRS Single Life Expectancy Table (Table I in Publication 590-B), not the Uniform Lifetime Table above. The factor is different and recalculated using your single life expectancy in the first distribution year, reduced by 1 each year after.
Aggregation rules: which accounts combine and which don't
You don't always have to take one RMD from each account. The aggregation rules determine your flexibility:
- Traditional IRAs, rollover IRAs, SEP IRAs, SIMPLE IRAs: Calculate the RMD from each account's balance, but you can take the total from any one account or combination. If you rolled your spouse's IRA into your own, both balances aggregate here.
- 403(b) accounts: Same aggregation rule — calculate separately, take from any 403(b).
- 401(k) accounts: Each plan is separate. You must calculate and take the RMD from each employer plan individually. They do not aggregate with IRAs or with each other.
- Roth IRAs: No RMD during your lifetime — ever.
- Roth 401(k)s: No lifetime RMD starting 2024, under SECURE 2.0 § 325.1
The QCD strategy: satisfy your RMD tax-free
If you're charitably inclined, this is one of the best tax moves available to widows with large RMDs.
A Qualified Charitable Distribution (QCD) lets you direct money from your IRA directly to a qualified charity, starting at age 70½. The amount transferred:3
- Counts toward satisfying your RMD for the year
- Is excluded from your taxable income entirely (unlike a regular withdrawal + donation)
- Reduces your MAGI — which matters for IRMAA and Social Security taxation thresholds
2026 QCD annual limit: $111,000 per person (inflation-indexed under SECURE 2.0; was $108,000 in 2025).
The mechanics: you request a check from your IRA custodian made payable directly to the charity (or charities). You cannot receive the funds yourself and then donate — that does not qualify as a QCD. Most major custodians have a QCD form or online process. The donation must be complete by December 31.
IRMAA: the hidden cost of large RMDs as a single filer
Medicare Part B and Part D premiums are income-based. For 2026, single filers with MAGI above $109,000 pay a surcharge on top of the standard $185.00/month Part B premium. The surcharge tiers add $600 to $5,800+ per year depending on income level.
The tricky part: IRMAA uses your income from two years prior. Your 2026 premiums are based on your 2024 tax return. If your RMDs (plus Social Security plus other income) keep pushing you over $109,000 as a single filer, you pay the surcharge every year — a $600–$5,800+ annual penalty on top of your regular premiums.
Strategies to manage it: QCDs (reduce MAGI directly), Roth conversions in earlier years (reduce future RMD size), and the SSA-44 appeal if a one-time income spike was the cause. See The Widow's Tax Penalty for the full IRMAA picture, and Roth Conversion Strategy for Widows for how converting now can reduce future RMDs permanently.
Common RMD mistakes after a spouse dies
- Missing the year-of-death RMD. If your spouse was already taking RMDs and died before taking the full amount for the year, the remaining portion for that year must still be distributed. It falls to you as the surviving spouse. Failing to take it triggers a 25% excise tax on the missed amount (reduced to 10% if corrected within two years).
- Rolling over before age 59½ and losing penalty-free access. Once inside your own IRA, early withdrawals cost 10%. If you need income now and you're under 59½, stay in the inherited account until you turn 59½, then roll over.
- Assuming Roth accounts are RMD-free after rollover. An inherited Roth IRA kept as inherited is subject to RMDs; roll it into your own Roth IRA to eliminate them. An inherited Roth 401(k) is now also RMD-free after rollover, since SECURE 2.0 eliminated Roth 401(k) lifetime RMDs.
- Taking an IRA RMD to satisfy a 401(k) RMD. These don't cross-aggregate. If you have a 401(k) still at a former employer, that RMD must come from that plan — you cannot satisfy it by taking extra from your IRA.
- Doing a QCD after a deductible contribution. A QCD is only excludable from income if you haven't made a deductible IRA contribution in the same year. The ordering rules are complex; don't combine them without professional guidance.
