Each week, in our Ask the Editor series, Joy Taylor, The Kiplinger Tax Letter editor, answers questions on topics submitted by readers. This week she’s looking at five questions on how to file a tax return for someone who died. (Get a free issue of The Kiplinger Tax Letter or subscribe.)
1. Filing a joint return with a deceased spouse
Question: My husband died last year. Can I file a joint 2025 Form 1040 even though he’s no longer with us?
Joy Taylor: When someone is deceased, the decedent’s personal representative is generally required to file any final tax returns for the deceased person. That includes federal income tax returns that the decedent would have been required to file for the year of his or her death. A personal representative can be an executor, administrator, or anyone else who oversees the decedent’s property.
Since you were married in 2025, you would mark “married filing jointly” for the filing status and write your deceased spouse’s name and your name and address. If filing by paper, write “deceased” at the top of the 1040. If using tax preparation software, the software will automatically do this for you.
If there is a court-appointed representative, that person must also sign the 1040. If not, you would sign and write “filing as surviving spouse” in the decedent’s signature box.

If the return shows a refund due, there’s nothing you need to do to receive the refund.
2. Filing a return for a deceased sibling
Question: My brother died last year. He was not married. I am the executor of his estate. How do I file his final 2025 federal tax return?
Joy Taylor: Since your brother wasn’t married, here are the rules for filing a tax return for an unmarried decedent. Mark his filing status as single or head of household. Write his name on the name line and your name and address in the remaining name and address field (since you are the executor of your brother’s estate).
If filing a paper return, put “deceased” at the top of the Form 1040 and your brother’s name and date of death. Tax preparation software will do this once you let it know the filer is deceased.
If you are a court-appointed or court-certified personal representative, then you should sign the return. As executor of your brother’s estate, you would sign as the personal representative.
If your brother is due a refund, you may have to complete and attach Form 1310 to the return. This rule doesn’t apply if you are a court-appointed or court-certified personal representative. Instead, you would have to attach to the return a copy of the court document showing the appointment.
3. Filing status after loss of a spouse
Question: My wife of 48 years died last September. When she was alive, we always filed joint returns. But now I want to file a separate return for 2025. Can I do this?
Joy Taylor: Yes. You, as the surviving spouse, can file your deceased wife’s final return either as married filing joint or married filing separate. If you file a 2025 joint return with your deceased spouse, you would follow the instructions set forth in the answer to question 1 above. If you file a separate return for yourself for 2025, be sure to also file your deceased wife’s separate 2025 return.
4. Filing a return for a widow with young kids
Question: My husband died suddenly last year. We have three young children under the age of 18. I know that I can file a joint tax return for 2025. But what about for 2026? What filing status should I use on my 2026 tax return?
Joy Taylor: You are correct that you can file a joint federal tax return for 2025. You would follow the instructions set forth in the answer to question 1.
For your 2026 return, it might benefit you to use the qualifying widow filing status. This lets surviving spouses with dependent children use the income tax brackets and standard deductions for joint filers for two years after the decedent’s death.
This means that if you remain unmarried, you can use the qualifying widow status on your 2026 and 2027 federal tax returns.
5. Other resources to find help
Question: A good friend of mine passed away last year. Are there any IRS resources I can turn to in figuring out how to file her final 2025 tax return?
Answer: Yes. The IRS has an online tool to help you file a deceased person’s tax return. It’s an interactive tax assistant. You will need to enter some basic information, and it will give you an answer. The tool is called “How do I file a deceased person’s tax return?“
Note that the IRS’s interactive tax assistant will also help answer questions on nearly 60 other topics, including who qualifies as a dependent, filing an amended return and much more. Go to www.irs.gov/help/ita to access the IRS tax assistant and to see a list of topics.
Additionally, you can find helpful information in IRS Publication 559, Survivors, Executors, and Administrators, and in the instructions to Form 1040.
