After a Spouse Dies: 6 Rules That Protect You

Losing a spouse is one of the most difficult experiences life brings — and within weeks of that loss, financial decisions start coming at you that can have permanent consequences.

The good news: you don't have to rush most of them. Here are six rules that protect you, and two real deadlines you shouldn't miss.

Rule 1: Transferring Accounts Is Not Taxable

Moving your spouse's IRA, 401(k), or brokerage account into your name does not trigger income tax. There is no tax until you actually withdraw or sell the assets inside those accounts.

Don't let a financial institution's paperwork urgency pressure you into making decisions about distributions before you're ready. The transfer itself is a housekeeping step, not a taxable event.

Rule 2: You Get a Step-Up in Cost Basis

Brokerage holdings (taxable accounts, not IRAs) reset to their date-of-death fair market value — wiping out any capital gains that accrued during your spouse's lifetime.

• Most states: Your spouse's half of joint accounts gets stepped up
• Community property states (CA, TX, AZ, WA, and others): Both halves step up

This means you could sell those holdings with significantly reduced — or zero — capital gains tax. Get a professional to review this before you sell anything.

Rule 3: Retirement Accounts Roll Into Yours

As the named beneficiary on your spouse's IRA or 401(k), you have a unique option unavailable to any other beneficiary type: you can roll the account directly into your own IRA.

This means:

• No 10-year distribution deadline (which non-spouse beneficiaries face)
• Roth accounts stay tax-free when rolled into your own Roth IRA
• You treat the money as if it were your own retirement savings from the start

Rule 4: You Can Still File Jointly That Year

The year your spouse dies, you qualify to file a Married Filing Jointly return. This gives you the $32,200 standard deduction and the wider, lower tax brackets that come with joint filing.

The following year, you may qualify as a "Qualifying Surviving Spouse" for an additional two years — maintaining joint-equivalent brackets if you have a dependent child at home. After that, you file as Single, which narrows your brackets significantly.

This is a planning consideration: the two or three years after a spouse's death are often the lowest-tax years you'll have left. Roth conversions during this window can be powerful.

Rule 5: A Final Tax Return Is Required

Income earned from January 1 through the date of death must be reported on a final individual return. The brokerage, bank, and retirement account custodians will issue 1099s. Make sure you or your advisor accounts for all of them.

This return is often filed by the surviving spouse or the estate executor.

Rule 6: Few Decisions Are Urgent

You do not need to immediately sell, withdraw, or restructure assets. The biggest financial mistakes after a spouse's death happen when people move too quickly under emotional pressure.

Take your time. Get professional guidance. The accounts will be there when you're ready.

The Two Real Deadlines

1. Your spouse's final-year RMD If your spouse was 73 or older and had not yet taken their RMD for the year of death, that distribution must still come out. Missing it triggers the 25% penalty.

2. Filing Form 706 to preserve the estate exemption If your spouse's estate is large enough, filing Form 706 within 9 months of death (6 months with extension) preserves the unused portion of their estate tax exemption — potentially $15 million — which can be added to yours through "portability." Missing this deadline can cost your heirs millions.

The financial period immediately following a spouse's death is one of the most consequential — and one of the most poorly navigated — in retirement planning. The rules above protect you, but they require action at the right time.
