What happens to my retirement taxes after one spouse dies?

For many couples, the surviving spouse ends up with somewhat less income but a higher tax rate. The reason is filing status. Within a year or two, the survivor usually files as a single taxpayer, with narrower brackets and a smaller standard deduction, while much of the household’s income continues. Planning while both spouses are living can soften the change.

How does filing status change?

In the year a spouse dies, the survivor can generally still file a joint return. After that, most surviving spouses file as single. A surviving spouse who has a dependent child living at home, and hasn’t remarried, may use the qualifying surviving spouse status for the two years after the year of death, which keeps joint-return tax rates for that time. Many retirees don’t have a dependent child, so the change to single filing comes the following year.

Why can taxes rise when income falls?

The brackets and standard deduction for single filers are about half those for joint filers. For 2026, for example:

Meanwhile, much of the income can continue. A surviving spouse keeps the higher of the two Social Security benefits, not both. Pensions may continue in part. Required distributions from retirement accounts continue, now in the survivor’s name. The result can be similar taxable income spread across brackets half as wide.

What else changes?

• Medicare premiums. The surcharge is based on income from two years earlier, when you may still have filed jointly. Social Security lists the death of a spouse as a life-changing event, and you can ask it to use more recent income.
• Cost basis. The deceased spouse’s share of jointly owned investments generally gets a new cost basis at its value on the date of death. In community property states, the entire community property can. That can reduce capital gains if those assets are later sold.
• Retirement accounts. A surviving spouse has choices other beneficiaries don’t, including treating an inherited IRA as their own. The right choice depends on age and when the income is needed.

What planning can help in advance?

• Project the survivor’s taxes, not just the couple’s, using single-filer brackets.
• Consider Roth conversions while you still file jointly and the brackets are wider. See Should I convert my IRA to a Roth before retirement?
• Review beneficiary designations and account titling so assets pass the way you intend.
• Look at Social Security claiming as a couple, since the survivor keeps the larger benefit.
• Decide which accounts fund spending first, with the survivor’s tax picture in mind.
• Keep a simple record of accounts, advisors, and key contacts, so the survivor isn’t searching for them.

Not every decision has to be made right away.

After a loss, some decisions have deadlines, such as the final joint return and choices about inherited retirement accounts. Many others can wait. A short, clear list of what’s due, and when, makes the first year easier.

Frequently asked questions

Can I still file jointly for the year my spouse died?

Yes. The year your spouse died is the last year you can file a joint return with them. From the next year on, your filing status depends on your situation, as described above.

Will I receive both of our Social Security benefits?

No. A surviving spouse receives the higher of the two, not both.
