Filing a Final Tax Return for a Deceased Person in Texas

When someone passes away in Texas, their tax obligations don't disappear. If you're the executor, surviving spouse, or personal representative of someone who has died, you're likely wondering how to handle that last federal income tax return. Filing the final income tax return for a deceased person is one of the most important responsibilities you'll take on and getting it wrong can delay estate distributions, trigger IRS notices, or create personal liability. This guide walks you through exactly what to do, step by step.

What Is a Final Income Tax Return for a Deceased Person?

A final income tax return is the last individual federal tax return (Form 1040) filed on behalf of someone who has died. It covers income earned from January 1 through the date of death. Any income received after death such as interest, dividends, or rental income is reported separately on the estate's tax return, not the individual's final return.

Texas does not have a state income tax, so you only need to worry about the federal return. However, if the deceased owned property or had income in a state that does levy income tax, separate state filing rules may apply.

Who Is Responsible for Filing the Final Return?

The personal representative of the estate usually an executor named in the will or an administrator appointed by a Texas probate court is responsible for filing. If no representative has been appointed, the surviving spouse can file a joint return. In some cases, a responsible party like an adult child or close family member may file on behalf of the deceased.

If you've recently been named executor, you may also need to understand your broader tax responsibilities as a Texas executor, which extend beyond just the final return.

What Tax Year and Forms Apply?

The final return covers a short tax year from January 1 to the date of death. You'll use the same Form 1040 that the person would have filed if still alive. Key details:

Filing status: If the person was married, the surviving spouse can file jointly for the year of death, which often results in a lower tax bill.
Deductions and credits: The full standard deduction is available for the year, even though it's a partial year.
Income to report: Only income received before death goes on the final 1040. Wages earned but not yet paid, bank interest accrued, and similar items are still reportable on the individual return.

You may also need to file other tax forms depending on the estate's complexity. Our guide on what tax forms an executor files in Texas covers those additional filings.

How Do You Sign and Submit the Final Return?

This is where many executors get confused. Here's how it works:

If you're the surviving spouse filing jointly: Sign the return as usual. Write "Filing as Surviving Spouse" in the signature area.
If you're the executor or personal representative: Sign the return and write your name and "Executor" (or "Personal Representative") below the deceased's signature line. Attach a copy of the court document showing your appointment.
If there's no executor or court-appointed representative: Write "Filing for Deceased" on the signature line and attach Form 1310, Statement of Person Claiming Refund Due a Deceased Taxpayer, if you're claiming a refund.

What If There's a Refund?

If the final return shows a refund, Form 1310 must be filed unless the surviving spouse is filing a joint return. The IRS won't release a refund to anyone without proper documentation showing the right to receive it.

What About Income Received After Death?

This is one of the most common areas of confusion. Any income the deceased earned before death but received after like a final paycheck still goes on the individual's final 1040. But income that accrues after the date of death, such as:

Stock dividends paid after death
Rental income collected by the estate
Interest on estate bank accounts

This type of income gets reported on the estate's own tax return, Form 1041. The estate needs its own tax ID number for this. If you haven't obtained one yet, read our article on when a Texas executor must get a tax ID number for the estate.

When Is the Final Return Due?

The deadline follows the same rules as any individual return April 15 of the year after the death. For example, if someone died in June 2024, the final return is due April 15, 2025.

You can request an extension using Form 4868, which gives you until October 15. But an extension to file is not an extension to pay any tax owed is still due by the April deadline, and late payments accrue interest and penalties.

Common Mistakes Executors Make

Filing a final return for a deceased person involves several pitfalls. Here are the ones that come up most often:

Reporting post-death income on the final 1040. This inflates the individual's income and may trigger an IRS notice. Post-death income belongs on the estate return.
Forgetting to file Form 1310. Without it, the IRS will not issue a refund to the person claiming it.
Missing the filing deadline. Tax penalties can reduce what beneficiaries receive from the estate.
Not filing at all. Even if the deceased had limited income, filing a final return closes out the tax account and prevents future issues with the IRS.
Failing to report all income sources. Executors sometimes miss 1099 forms from banks, brokers, or employers that were issued in the deceased's name.

Do You Need a Tax Professional?

If the estate is straightforward a W-2, some bank interest, maybe a pension you may be able to handle the final return yourself. But if there are investment accounts, rental properties, business income, or estate tax considerations, working with a CPA or tax attorney experienced in estate taxation is a smart move. Errors on estate-related returns can create personal liability for executors.

What If the Deceased Owed Taxes?

If the final return shows taxes owed, the estate is responsible for paying. The executor should use estate funds to cover the liability. Under IRS rules, the executor can be held personally liable for unpaid taxes if estate assets were distributed to beneficiaries before settling the tax debt.

The IRS may also file a federal tax lien against the estate. If there aren't enough liquid assets to pay, you may need to sell estate property or negotiate a payment plan with the IRS.

Quick Checklist for Filing the Final Return
