Filing the Final Tax Return for a Deceased Person

Filing the final tax return for a deceased person means preparing a standard Form 1040 that reports the income they earned from January 1 through the date of death, claiming the deductions and credits they would have been entitled to, and submitting it by the usual April 15 deadline of the following year. A surviving spouse or a court-appointed personal representative usually handles the filing. The return looks like any other individual return, with two differences: the tax period ends on the date of death, and the top of the first page is marked to show the taxpayer has died.

Who Can File

The IRS recognizes three people who can file for someone who has died: a court-appointed personal representative, a surviving spouse, or whoever is in charge of the deceased person’s property.¹

A personal representative is an executor named in the will or an administrator appointed by a probate court when there is no will or the named executor cannot serve. This person has the broadest authority. They file the final return and any prior-year returns the deceased never got around to filing.²

A surviving spouse can file a joint return with the deceased for the year of death, as long as they did not remarry before the end of that calendar year. If no personal representative has been appointed by the filing deadline, the surviving spouse can file that joint return alone.² Filing jointly usually produces a lower tax bill because joint filers get a larger standard deduction ($32,200 for 2026, compared with $16,100 for single filers) and more favorable brackets.³ There is a trade-off worth understanding before signing: a joint return makes the surviving spouse and the estate jointly and severally liable for the tax, interest, and any penalties on the return. If the deceased had unreported income or aggressive deductions, that liability follows the surviving spouse.

When there is no representative and no surviving spouse, the person in charge of the deceased’s property files the return and signs as “personal representative.”¹

A court-appointed representative can also file Form 56 to formally notify the IRS of the fiduciary relationship. The filing is voluntary, but it directs IRS correspondence about the deceased person’s account to the representative rather than to an old address.⁴

Records to Gather Before You Start

You need the deceased person’s Social Security number, which the IRS uses to identify every filing tied to them. Order several certified copies of the death certificate at the same time. Banks, brokerages, former employers, and insurance companies each want their own copy before they release account information or tax documents, and having extras on hand saves weeks. Certified copy fees vary by state, generally $5 to $30 each.

Then collect every income document covering January 1 through the date of death: W-2s from employers, 1099-INT and 1099-DIV forms from banks and brokerages, 1099-Rs for retirement distributions, and any other 1099s. These belong on the final return only to the extent they represent income earned or received before death. Income the deceased had a right to but did not receive until after death belongs elsewhere (see below).²

If the deceased failed to file returns for any prior year, those returns still have to be prepared and filed. The IRS can provide wage and income transcripts to help reconstruct what was owed.²

Completing the Final Form 1040

Use the standard Form 1040 (or 1040-SR for seniors). Write “Deceased,” the person’s name, and the date of death across the top of the first page. Put the representative’s name and mailing address on the “care of” line so the IRS knows where to send correspondence.⁵

Report all income from January 1 through the date of death and claim every eligible credit and deduction, just as you would for a living taxpayer. The tax period is simply shorter because it ends on the date of death rather than December 31. The full standard deduction still applies even though the year was cut short, which is why final returns often produce a refund, especially when the death occurred early in the year.

Signing the Return

How you sign depends on your role. A court-appointed representative signs their own name and writes their title, for example “Executor for the Estate of Jane Smith.” A surviving spouse filing jointly when no representative has been appointed signs their own name and writes “filing as surviving spouse” in the signature area. Anyone else files and signs as “personal representative.”¹

Claiming a Refund

If the return shows a refund, you may need to attach Form 1310, Statement of Person Claiming Refund Due a Deceased Taxpayer. Two groups do not: a surviving spouse filing an original or amended joint return, and a court-appointed representative who attaches the court certificate to the return. Everyone else claiming a refund on behalf of the deceased must file Form 1310.⁶

E-Filing or Paper

You can file on paper or through an authorized electronic filing service. E-filing is faster: refunds on e-filed returns typically arrive within three weeks, while paper returns take six weeks or longer.⁷ Paper returns go to the IRS service center for the filer’s region, listed in the Form 1040 instructions.

Deductions Worth a Closer Look

Medical expenses have a rule worth knowing. Bills the deceased paid before death are deductible on the final return to the extent they exceed 7.5% of adjusted gross income, if you itemize. Medical expenses paid out of the estate after death can also be deducted on the final income tax return rather than on the estate tax return, provided the expenses are paid within one year of the day after death and you attach a statement to the return waiving the right to claim the same expenses on the estate tax return. This election only covers the deceased person’s own medical expenses, not those of dependents.² For estates well below the federal estate tax threshold, taking these expenses on the income tax return is usually the better choice, because the income tax savings are real while the estate tax deduction would produce nothing.

Income That Arrives After Death Goes Elsewhere

Some money the deceased had a right to receive shows up only after they die: unpaid wages, final retirement account distributions, accrued interest, deferred compensation. This is called “income in respect of a decedent,” and it does not go on the final Form 1040. Instead, whoever receives it reports it. The estate reports it on Form 1041, or if it passes directly to a beneficiary, the beneficiary reports it on their own return.⁸

Inherited IRAs are the most common example. Distributions from an inherited traditional IRA are fully taxable to the beneficiary as ordinary income (assuming the original contributions were deductible). A non-spouse beneficiary cannot roll the inherited IRA into their own account. Because that income also sits in the deceased’s gross estate for estate tax purposes, the recipient can claim an itemized deduction for the estate tax attributable to it, which softens but does not eliminate the overlap.²

Deadline, Extension, and Penalties

The final return is due on April 15 of the year after death, the same deadline as any other individual return. Someone who dies on March 3, 2025, has a final return covering January 1 through March 3 that is due April 15, 2026.²

If you need more time, file Form 4868 before the April deadline for an automatic six-month extension to October 15.⁹ The extension covers the paperwork only. Any tax owed is still due April 15, so send an estimated payment with the extension request even if the final number is not settled.

Missing the deadline without an extension triggers a failure-to-file penalty of 5% of the unpaid tax for each month or partial month the return is late, up to 25%.¹⁰ Unpaid tax also accrues a separate failure-to-pay penalty of 0.5% per month, also capped at 25%, plus interest.¹¹ These penalties come out of estate assets that would otherwise reach heirs.

What Comes After the Final 1040

The final Form 1040 covers the person’s lifetime income only. After the date of death, income the estate generates on its own, such as interest, rental income, or dividends on assets titled to the estate, gets reported on a separate return, Form 1041, U.S. Income Tax Return for Estates and Trusts. The estate must file Form 1041 if it has gross income of $600 or more in a tax year, or if any beneficiary is a nonresident alien.¹² The estate has its own employer identification number and its own brackets, and its tax year does not have to be the calendar year. The personal representative files it. Estates that take a year or more to settle often generate a 1041 filing obligation that gets overlooked.

Two other filings are worth knowing about even though they sit outside the final 1040. The federal estate tax is a separate tax that applies only to very large estates; for 2026 the basic exclusion amount is $15,000,000.¹³ Married couples below the threshold should still look at portability, which lets a surviving spouse inherit the unused portion of the first spouse’s exclusion but only if Form 706 is filed and the election is made within nine months of death, or up to five years later if the estate was not otherwise required to file.¹⁴ And in the two tax years after the year of death, a surviving spouse maintaining a home for a dependent child may qualify to file as a Qualifying Surviving Spouse, keeping the joint-return standard deduction and brackets rather than dropping to single-filer treatment.
