How to File a Deceased Person's Final Income Tax Return

By Joy Taylor, Kiplinger Consumer News Service (TNS)

Benjamin Franklin coined the famous saying that “in this world, nothing is certain but death and taxes.” But what about when death and taxes coincide, such as when someone dies during the year and has a tax filing obligation?

Unfortunately, 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.

Filing a final 2022 Form 1040 or 1040-SR for a deceased spouse

If your spouse died during the year, you are considered married for the entire year for federal income tax purposes, provided you didn’t remarry that year. So, for example, if your spouse died last year and you didn’t remarry before Dec. 31, 2022, you can file a joint 2022 return. The return would show your spouse’s income before death, and would show your income for the entire year.

You would mark “married filing jointly” for your filing status and include your spouse’s name and your name and address as normal in the name and address fields of the Form 1040 or 1040-SR. If filing a paper return, write the word “deceased,” along with the decedent’s name, and date of death, at the top of the 1040 or 1040-SR. If you are using tax preparation software, the software will do this automatically for you once you mark that the spouse is deceased and enter the date of your spouse’s death.

If there is a court-appointed personal representative, then that representative must sign the return along with the surviving spouse. If there is no court-appointed representative, then the surviving spouse would sign, and write “filing as surviving spouse” in the decedent’s signature box.

If you are filing a joint return that shows a refund due, there is nothing that you need to do to receive the refund other than filing the tax return.

If you remarried before the end of 2022, you would file a joint return with your new spouse, and your deceased spouse’s filing status will be married filing separately.

Here’s a tip: The qualifying widow or widower filing status lets surviving spouses with dependents use the income tax brackets and standard deductions for joint filers for two years after a spouse’s death.

For example, if your spouse died last year and you have two minor children, you can file a joint 2022 return. Then for your 2023 and 2024 returns, you can file as a qualifying widow or widower, provided you are still unmarried at the end of 2023 and 2024 and claim dependent children for these years.

Filing a final 2022 Form 1040 or 1040-SR for an unmarried decedent

The decedent’s final 2022 federal income tax return would report his or her income and expenses before death. If filing a paper return for the decedent, write the word “deceased” and the decedent’s name and date of death at the top of the 1040 or 1040-SR. If you’re using tax preparation software, the software will do this automatically for you once you mark that the filer is deceased and enter the date of death.

You would also mark the decedent’s filing status as single or head-of-household, depending on the situation. You write the decedent’s name on the name line of the 1040 or 1040-SR and the personal representative’s name and address in the remaining name and address field.

If there is a court-appointed or court-certified personal representative, that representative should sign the return. If not, and there is no surviving spouse, then whoever is in charge of the decedent’s property signs the return as the personal representative.

If a refund is due to the decedent, you may have to complete and attach Form 1310 to the final 1040 or 1040-SR. This rule does not apply to surviving spouses who file a joint 2022 return with the decedent. Nor does it apply to court-appointed or court-certified personal representatives, who are instead required to attach to the return a copy of the court document showing the appointment. However, all other filers who are requesting the decedent’s tax refund must attach the Form 1310.

Here is another tip: The IRS has an interactive tax assistant on its website to help you figure out how to file a deceased person’s federal income tax return. The online tool, (i.e., “How do I file a deceased person’s tax return?”), asks several questions, including the marital status of the decedent, whether the decedent is owed a refund and whether there is a court-appointed representative, or a personal representative designated by the will.

What happens if you don’t file a deceased person’s taxes?

The consequences for not filing a decedent’s final federal income tax return depend on whether the decedent owes money to the IRS or is due a refund for the year.

If the decedent is required to file a return for the year and owes money with the final return, then the IRS will eventually send a notice to the decedent’s last-known address about the requirement to file a return.
If the taxes aren’t paid, then the IRS could eventually go after the executor, or maybe even the decedent’s heirs to the extent the heirs received the decedent’s property upon death, for the unpaid taxes.
If the decedent is owed a refund, and no final income tax return is ever filed, then the decedent’s heirs will not get the refund payment.
