Filing a Final Tax Return for Someone Who Died

In the stack of paperwork that follows a death, one item surprises almost every family: the person who died still owes the IRS a tax return. Wages earned in the final months, pension payments, interest, Social Security benefits, all the income received up to the date of death has to be reported on one last Form 1040, and someone living has to file it.

The mechanics are simpler than they sound, but they involve a few rules that exist nowhere else in the tax code, including a form most people have never heard of that exists solely to get a refund released to the family. The IRS collects the essentials on its page for filing the final returns of a deceased person. Here is how it works in practice.

Who is responsible for filing

The job belongs to the personal representative: the executor or administrator appointed by a court, or, if there is no formal estate, the surviving spouse or whoever has taken charge of the person’s property. A surviving spouse can generally still file a joint return for the year of death, covering the couple’s combined income for the full year, unless the spouse remarries before year end. If there is a court-appointed representative and a surviving spouse, they act together on the joint return.

The return itself is an ordinary Form 1040 for the year of death, reporting income the person received from January 1 through the date of death. It uses the same deductions, credits, and filing statuses as anyone else’s return; dying partway through the year does not prorate the standard deduction.

The deadline does not move

The final return is due on the normal filing deadline for the year of death. For someone who dies in 2026, the final Form 1040 is due by mid-April 2027, and a family that filed this past spring for a 2025 death was on the usual schedule too. An extension can be requested the ordinary way, though as always it extends the time to file, not the time to pay. If tax is owed, it is paid from the estate’s funds, not out of the representative’s own pocket.

How to mark the return and who signs

The IRS asks that the word “deceased,” the person’s name, and the date of death be written across the top of the return, and tax software has an equivalent entry. Signatures follow a simple hierarchy, described on the IRS deceased person page: a court-appointed representative signs in their official capacity; a surviving spouse filing jointly signs and writes “filing as surviving spouse” in the decedent’s signature space; and anyone else who has taken responsibility for the person’s affairs signs as “personal representative.”

Getting a refund released: Form 1310

Refunds are where families most often get stuck, because the IRS will not simply mail a dead person’s refund to whoever asks. The key document is Form 1310, Statement of Person Claiming Refund Due a Deceased Taxpayer. Whether you need it depends on who you are.

A surviving spouse filing a joint return does not need Form 1310; the refund comes as part of the joint filing. A court-appointed executor or administrator filing the decedent’s original return also skips Form 1310, but should attach a copy of the court certificate showing the appointment. Everyone else, an adult child wrapping up a small estate with no probate, for example, attaches Form 1310 to the return, certifying that they will distribute the refund according to state law. Get this right the first time; a missing 1310 or court certificate is one of the most common reasons a final-return refund sits unprocessed for months.

Income after death belongs to the estate

The final 1040 has a clean cutoff: the date of death. Income that arrives afterward, a final paycheck issued the following week, interest that keeps accruing, a house sold by the estate, belongs to the estate as its own taxpayer. If the estate collects $600 or more of gross income in its tax year, the representative files a separate income tax return for the estate, Form 1041, under its own employer identification number. Many modest estates never cross that threshold, but knowing where the line sits keeps the right income on the right return.

The reference worth keeping open

For everything beyond the basics, survivor annuities, medical expenses paid after death, income in respect of a decedent, the standard reference is IRS Publication 559, Survivors, Executors, and Administrators, written for exactly the person doing this job for the first time.

None of this paperwork is what a grieving family wants to think about, and none of it is urgent in the first weeks. But the final return is one of the few estate tasks with a hard federal deadline and, frequently, money coming back. Handled once, correctly marked, correctly signed, with Form 1310 attached when it applies, it closes the person’s account with the IRS for good.
