The executor or estate handles the final tax return, not the heirs

When someone dies, their income and assets do not automatically stop being taxable. The person appointed to manage the estate — called the executor, personal representative, or administrator depending on your state — must file a final federal income tax return for the year the person died. This return covers all income earned from January 1 through the date of death.

The executor files this return using the deceased person's Social Security number on IRS Form 1040. The return is due by the normal important date (usually April 15 of the following year), though the executor can request an extension. If the estate itself earns income after death — from rental property, investments, or a business — the executor may also need to file a separate estate tax return on Form 1041.

Heirs are not personally responsible for the deceased person's income tax debt unless they inherit the estate and the estate does not have enough money to pay what is owed. In that case, the debt comes out of what they would have received.

Key Takeaways

  • The executor files one final income tax return for the deceased person covering income earned up to the date of death, using the person's Social Security number.
  • If the estate earns income after death, the executor files a separate estate return on Form 1041 for each year the estate remains open.
  • Unpaid income tax becomes a debt of the estate and reduces what heirs receive, but heirs are not personally liable unless they inherit the estate.
  • The executor should notify the IRS of the death by sending a copy of the death certificate and a letter to the IRS address for the state where the person lived.
  • Some states also require a state income tax return, which follows the same rules as the federal return.

How to notify the IRS that someone has died

The executor should send written notice to the IRS as soon as practical after the death. This prevents the IRS from sending notices or bills to the deceased person's address and stops the agency from processing tax returns filed under that Social Security number after the person's death.

To notify the IRS, send a letter to the IRS office that serves your state. Include a copy of the death certificate, the deceased person's name, Social Security number, and the date of death. Address the letter to the Internal Revenue Service, Attn: Adjustments, and use the mailing address for your state (found on IRS.gov under "Where to File"). Keep a copy for your records.

If the deceased person had a tax professional or accountant, that person can also notify the IRS on behalf of the estate. The IRS will flag the account so that future correspondence goes to the executor instead of the deceased person.

Filing the final income tax return

The executor gathers all income documents for the year of death — W-2 forms from employers, 1099 forms from banks and investment accounts, rental income statements, and any other income sources. The return is filed on Form 1040, the same form used for living taxpayers, but marked "Deceased" with the date of death written across the top.

The return must include all income earned from January 1 through the date of death. If the person died on June 15, the return includes income only through that date, not the full year. The standard deduction for the year of death is the same as for a living person of that age and filing status, unless the person was married and the surviving spouse files a joint return (which is often the best choice for tax purposes).

The executor signs the return and writes "Executor for [Deceased Person's Name]" next to the signature. The return is mailed to the IRS address for the state where the person lived. If a refund is owed, it goes to the estate, not to individual heirs.

Estate income tax returns when the estate stays open

If the estate takes time to settle — which is common when there are multiple heirs, property to sell, or debts to pay — the estate itself may earn income. Interest on bank accounts, dividends from stocks, or rent from real estate all become taxable income of the estate, not the heirs.

The executor files Form 1041 (U.S. Income Tax Return for Estates and Trusts) for each year the estate remains open and earns more than $600 in income. This return is due by the same important date as individual returns (April 15), though an extension can be requested. The estate gets its own tax identification number, called an EIN, which the executor applies for using Form SS-4.

Income reported on Form 1041 can be distributed to heirs, in which case the heirs report it on their own returns, or it can be retained in the estate and taxed at the estate's tax rate. The executor decides how to handle this based on what is most tax-efficient for the situation.

State income tax returns

Most states that have an income tax require a final state return as well. The rules are similar to the federal return: the executor files for income earned through the date of death, using the deceased person's name and Social Security number. Some states allow the executor to file jointly with a surviving spouse, which may lower the total tax owed.

A few states have no income tax (including Florida, Texas, and Wyoming), so no state return is needed in those places. If the deceased person lived in one state but earned income in another, the executor may need to file returns in both states. The state tax department's website will have instructions for notifying them of the death and filing the final return.

What happens if taxes are owed but the estate has no money

If the final return shows a tax bill and the estate does not have enough cash to pay it, the executor must prioritize. Federal income tax is paid before most other debts, but after funeral expenses and certain court costs. If there is not enough money to pay everything, the executor pays in this order: funeral and administration costs, then federal taxes, then state taxes, then other debts, then distributions to heirs.

The executor should contact the IRS if the estate cannot pay the full amount owed. The IRS may set up a payment plan, though interest and penalties will continue to accrue. The executor can also request a delay in payment while the estate is being settled, though this is not automatic.

Heirs do not owe the tax personally, but they receive less from the estate because the tax reduces what is available to distribute. If the estate is insolvent (owes more than it is worth), some heirs may receive nothing.

Refunds and overpayments

If the final return shows that too much tax was withheld or paid during the year, the IRS will issue a refund to the estate. The executor claims the refund on the final return and receives it in the estate's name. This money becomes part of the estate's assets and is distributed to heirs according to the will or state law.

If the deceased person had filed an extension for the prior year and did not file that return before death, the executor must file it. Any refund from that return also goes to the estate. The executor should gather all prior-year documents and file any outstanding returns to recover any refunds owed.

Frequently Asked Questions

Do I have to file a tax return if the person who died had very little income?

Yes, if the person had any income at all during the year of death, a return must be filed. The threshold is the same as for living people — for 2023, a single person needed at least $13,850 in income to be required to file. However, filing may still be worthwhile even below that threshold if taxes were withheld, because a refund could be claimed.

Can the surviving spouse file a joint return with the deceased person?

Yes. If the person was married at the time of death, the surviving spouse can file a joint return for the year of death. This is often beneficial because it may result in a lower tax rate and allows the couple's income and deductions to be combined. The surviving spouse signs the return and writes "Filing as surviving spouse" next to their signature.

What if the person owed taxes from a prior year?

Any unpaid tax from prior years becomes a debt of the estate. The executor should contact the IRS to find out what is owed and set up a payment plan if necessary. The IRS will have a record of the debt, and the executor can request a transcript showing what years have unpaid balances.

Who gets the refund if the final return shows an overpayment?

The refund goes to the estate and becomes part of the assets distributed to heirs. If there is a will, the refund is distributed according to its terms. If there is no will, state law determines who receives it, usually the surviving spouse and children in a set order.

Do I need to file an estate tax return on Form 1041?

Only if the estate earns income after the person's death and that income exceeds $600 in a given year. If the estate is settled quickly and earns no income, no Form 1041 is needed. The executor should track any interest, dividends, or rental income the estate receives while it is being settled.
