This article reflects federal IRS rules and notes general state differences as of June 2026 and covers tax year 2025 (the 2026 filing season). Tax law changes — confirm current figures before you file.
Quick Answer
For tax year 2025, the surviving spouse or the court-appointed personal representative files the deceased person’s final Form 1040. If no one is appointed, the person who manages the estate or pays the bills files it. They sign as “personal representative” and write “Deceased” across the top.
A death does not erase a tax bill, and it does not freeze a refund either. The Internal Revenue Service (the federal agency that collects taxes, called the IRS) still expects a final income tax return for the year your loved one died, and someone has to sign that return, claim any refund, and pay any balance owed. That job falls to a specific person — and picking the wrong person, or skipping the wrong form, can stall a refund for months.
About 2.8 million Americans die each year, according to the CDC’s mortality data, and most leave behind at least one tax return that still has to be filed. The deadline does not move because of the death — a 2025 final return is due April 15, 2026, the same as everyone else’s. This guide shows you exactly who is responsible, which forms to use, and how to claim a refund without delay.

Breaking Down the Roles: Who Can File
Filing for someone who died is not a free-for-all. The IRS recognizes a short list of people who may sign and submit the return, and the rules in IRS Publication 559 — the IRS guide for survivors and executors — spell out who that is. Knowing your exact role matters because it decides whether you sign alone, whether you need a court paper, and whether you must attach an extra form to get a refund.
The three roles that come up most are the surviving spouse, the court-appointed personal representative, and an informal next of kin who steps in when no court names anyone. Each has different powers and different paperwork. Below, each role gets its own plain-English explanation, the consequence of getting it wrong, and what you should do.
The Surviving Spouse
The surviving spouse is the husband or wife who was still legally married to the person at death. This is the simplest path because a spouse can usually file a joint return for the year of death, just as the couple did while both were alive. The spouse signs the joint return normally and also signs for the deceased, writing “filing as surviving spouse” in the deceased’s signature area.
The consequence of skipping the joint option is real money lost. A joint return for tax year 2025 gives a standard deduction of $30,000, while filing separately gives only $15,000 each, per the IRS standard deduction figures. A surviving spouse who files separately by mistake can overpay by thousands.
What you should do: if you did not remarry in 2025 and were married at the time of death, file a joint 2025 return unless a tax professional shows separate is better. The deadline is April 15, 2026.
The Court-Appointed Personal Representative
A personal representative is the person a probate court names to manage the estate — sometimes called an executor (named in the will) or an administrator (named when there is no will). Probate is the court process that settles an estate. This person holds a court document, often called “letters testamentary” or “letters of administration,” that proves their authority.
The consequence of this role is mostly good news: a court-appointed representative filing the original return does not need Form 1310 to claim a refund, as confirmed by IRS Topic No. 356. They simply attach a copy of the court certificate to the return. Miss that attachment, though, and the IRS can hold the refund.
What you should do: attach a copy of your court appointment to the return, sign as “personal representative,” and keep the original court paper safe — you will need it for banks and the IRS for months.
Informal Next of Kin (No Court Appointment)
Many small estates never go through probate, so no one is officially appointed. In that case, a family member — often an adult child, parent, or sibling — handles the final affairs. This person can still file the final return, but they cannot claim a refund as easily as a spouse or appointed representative.
The consequence here is the most common refund delay: an unappointed person claiming a refund must file Form 1310, the Statement of Person Claiming Refund Due a Deceased Taxpayer. Skip it and the IRS will not release the check to you.
What you should do: if you are not the spouse and not court-appointed, plan to file Form 1310 with the return whenever a refund is due. Keep the death certificate handy in case the IRS asks for it.
Which Situation Applies to You?
The right answer depends on your role and whether money flows in or out. Use this quick branch to find your path, then read the matching section above and the form steps below.
- You were married to the person and did not remarry in 2025: you are the surviving spouse — file a joint return, no Form 1310 needed.
- A court named you executor or administrator: you are the personal representative — attach the court certificate, no Form 1310 needed for the original return.
- No court appointment, and a refund is due: file Form 1310 with the return.
- No court appointment, and a balance is owed: file and pay; Form 1310 is not needed because no refund is being claimed.
- The estate itself earned more than $600 after death: you may also need Form 1041, the estate’s own income tax return.
The Final Form 1040: The Core Return
The heart of this whole process is the decedent’s final Form 1040, the standard individual income tax return. “Decedent” is the legal word for the person who died. This return covers income the person earned from January 1, 2025, up to the date of death — not the whole year unless they lived until December 31.
The final return works like any other 1040, with one key difference: it stops at the date of death. Wages, pension, interest, and dividends received before death go on this return. Income that arrives after death — like a final paycheck paid later or interest that posts afterward — usually belongs to the estate, not the final 1040.
The consequence of mixing these up is double-reporting or missed income, which can trigger an IRS notice and interest. For tax year 2025, interest on unpaid balances and penalties continues to run from April 15, 2026, even after death, per IRS rules on penalties.
How to Mark the Return as Final
At the top of the 1040, write “Deceased,” the person’s name, and the date of death across the top margin. The IRS uses this to flag the account and stop sending notices that assume the person is alive. The IRS guide for final returns confirms no separate death notice is required — the marked return tells them.
The consequence of forgetting this label is confusion: the IRS may keep the account open, send future-year reminders, or reject an e-filed refund. What you should do is mark the top clearly, enter the date of death in the software’s designated field, and keep a copy.
Signing the Final Return
Who signs depends on your role. A surviving spouse filing jointly signs their own name and signs for the deceased as “filing as surviving spouse.” A personal representative signs as “personal representative.” If both a spouse and an appointed representative exist, both should sign.
The consequence of an unsigned return is simple: the IRS treats it as not filed, which can create late-filing penalties of 5% of unpaid tax per month, up to 25%, under IRS failure-to-file rules. What you should do is confirm the correct signer before mailing, since many decedent returns must be paper-filed.
Form 1310: Claiming the Refund
Form 1310 is the form a person uses to claim a refund owed to someone who died. The current version is dated December 2025. It exists because the IRS will not simply mail a refund check in a dead person’s name to whoever asks — it needs proof of who should receive the money.
Not everyone needs it. A surviving spouse on a joint return does not. A court-appointed representative filing the original return does not, as long as the court certificate is attached. Everyone else claiming a refund does. Getting this wrong is the single most common cause of a frozen deceased-taxpayer refund.
Who Checks Which Box
Form 1310 asks you to identify yourself in Part I. Box A is for a surviving spouse requesting reissuance of a refund check. Box B is for a court-appointed representative (rare, used mainly on amended returns). Box C is for everyone else — the informal next of kin.
The consequence of the box you check is what proof you must provide. Box C filers answer questions about the will and may need to keep the death certificate available. What you should do is read the Form 1310 instructions and check only one box that matches your real role.
Where and How to File It
Attach Form 1310 to the final return and file it the same way. If the return is e-filed and Form 1310 is allowed, software submits it together; if not, you mail the paper return with the form. A refund check is then issued in the claimant’s name.
The consequence of mailing to the wrong address or omitting the form is a refund delay of several months. Paper deceased-taxpayer returns commonly take six weeks or longer to process, and refund claims can take longer, per general IRS processing guidance. What you should do is keep proof of mailing and check refund status after about six weeks.
Worked Example: Claiming a $1,840 Refund
Here is the math, step by step, so you can copy it. Maria’s father, Robert, died on May 10, 2025. He had no will and no probate, so no court appointed anyone. Maria handles his affairs and wants his refund.
- Robert’s wages, Jan 1 to May 10, 2025: $24,000
- Federal tax withheld from those wages: $2,600
- His 2025 standard deduction (single): $15,000
- Taxable income: $24,000 − $15,000 = $9,000
- Tax on $9,000 (2025 single brackets, roughly 10%): about $760
- Refund: $2,600 withheld − $760 tax = $1,840
Because Maria is neither a spouse nor court-appointed, she must attach Form 1310, checking Box C, to Robert’s final 1040 to receive the $1,840. Without it, the IRS holds the money. With it, the check is issued in Maria’s name.
The Estate’s Own Return: Form 1041
After death, the estate becomes its own taxpayer for income it earns. Form 1041 is the U.S. Income Tax Return for Estates and Trusts. It is separate from the final 1040 and covers income the estate receives after the date of death, such as interest, dividends, or rent.
The estate must file Form 1041 if it has gross income of $600 or more in the tax year, per the Form 1041 instructions. The personal representative files it, using an Employer Identification Number (EIN) for the estate, not the deceased’s Social Security number.
The consequence of ignoring this is unreported income and penalties on the estate. What you should do is get an estate EIN online for free, then track post-death income to see if it crosses $600. For a calendar-year estate, Form 1041 is due April 15 of the following year.
Estate Tax vs. Income Tax: Form 706
People confuse income tax with estate tax, but they are different. Form 706 is the federal estate tax return, a one-time tax on the value of everything a person owned at death — not on income. Most estates never owe it.
For deaths in 2025, Form 706 is generally required only if the estate is worth more than $13.99 million, the 2025 federal estate tax exemption. Because of that high threshold, fewer than 0.1% of estates owe federal estate tax. What you should do is assume Form 706 does not apply unless the estate is in the millions, and confirm with an estate attorney if it is close.
Federal vs. State: What Differs
Federal rules set the baseline, but states do not all follow them. Your state may require its own final income tax return for the deceased, and a handful of states impose their own estate or inheritance tax with much lower thresholds than the federal $13.99 million.
Never assume your state matches the IRS. States like Texas, Florida, and Washington have no personal income tax, so there is no state final income tax return to file — a complete and valid answer. Others, like Oregon and Massachusetts, levy estate tax starting around $1 million to $2 million, far below the federal line. What you should do is check your state revenue agency’s page for deceased-taxpayer rules before you file.
| Tax Type | Federal Rule (2025) |
|---|---|
| Final income tax return | Form 1040, due April 15, 2026, covers Jan 1 to date of death |
| Estate income tax return | Form 1041, required if estate income is $600 or more |
| Estate (death) tax | Form 706, required only if estate exceeds $13.99 million |
| Refund claim | Form 1310, unless spouse or court-appointed representative |
Scenario Tables: Three Common Situations
These three patterns cover most readers. Each shows what you do and what happens as a result.
Surviving Spouse, Refund Due
| What You Do | What Happens |
|---|---|
| File a joint 2025 return, sign as surviving spouse | Refund is issued; no Form 1310 needed |
| Use the $30,000 joint standard deduction | Lower tax than filing separately |
| Mark “Deceased” and date of death on top | IRS flags the account correctly |
Court-Appointed Executor, Refund Due
| What You Do | What Happens |
|---|---|
| Attach court certificate to the original return | Refund released without Form 1310 |
| Sign as “personal representative” | Return is accepted as valid |
| File Form 1041 if estate income hits $600 | Estate income is properly reported |
Adult Child, No Appointment, Refund Due
| What You Do | What Happens |
|---|---|
| File final 1040 with Form 1310, Box C | Refund check issued in your name |
| Skip Form 1310 | IRS holds the refund indefinitely |
| Keep the death certificate ready | You can answer IRS follow-up fast |
Named Examples
James, the surviving spouse. James’s wife, Linda, died in August 2025. They have a teenage son. For 2025, James files a joint return and signs as surviving spouse, claiming the $30,000 standard deduction. For 2026 and 2027, because he has a dependent child and has not remarried, he can file as a qualifying surviving spouse, keeping the lower joint tax rates, per the IRS filing status rules.
Priya, the court-appointed executor. Priya’s mother died with a will naming Priya executor. The probate court issues letters testamentary. Priya files the final 1040, attaches a copy of the court certificate, signs as personal representative, and the $920 refund is released — no Form 1310 required.
David, the unappointed son. David’s father died with a small estate and no probate. A $1,200 refund is due. Because David is neither spouse nor court-appointed, he files Form 1310 with Box C checked, attaches it to the final 1040, and the IRS issues the $1,200 check in his name.
Deadlines, Costs, and Timing
The final 2025 return is due April 15, 2026, the same as any 1040. You can request a six-month extension with Form 4868, pushing the filing deadline to October 15, 2026 — but an extension to file is not an extension to pay. Any tax owed still accrues interest from April 15.
Costs vary. Filing a simple final return yourself is free through IRS Free File if income qualifies. A CPA or enrolled agent typically charges a few hundred dollars for a final 1040, and more if Form 1041 or an estate is involved. Paper deceased-taxpayer returns and refund claims often take six weeks or longer to process.
What you should do: file on time even if you cannot pay in full, since the failure-to-file penalty (5% per month) is ten times larger than the failure-to-pay penalty (0.5% per month), under IRS penalty rules.
Mistakes to Avoid
- Skipping Form 1310 when you are not the spouse or executor. The IRS holds your refund until you file it.
- Filing separately as a surviving spouse. You lose the $30,000 joint standard deduction and may overpay by thousands.
- Forgetting to write “Deceased” and the date of death on top. The IRS may keep the account open and send wrong notices.
- Leaving the return unsigned. An unsigned return counts as not filed and can trigger a 5%-per-month penalty.
- Reporting post-death income on the final 1040. Income earned after death belongs on Form 1041, not the 1040.
- Confusing estate tax with income tax. Most estates owe no Form 706 estate tax; do not file it needlessly.
- Missing the April 15 deadline thinking death pauses it. It does not — penalties and interest still run.
- Using the deceased’s Social Security number for estate income. The estate needs its own EIN for Form 1041.
Do’s and Don’ts
- Do mark the return “Deceased” with the date of death, so the IRS flags the account right away.
- Do attach the court certificate if you are an appointed executor, because it replaces Form 1310 for the refund.
- Do file Form 1310 if you are an informal next of kin claiming a refund, or the money stays frozen.
- Do file a joint return as a surviving spouse, since it gives the largest standard deduction.
- Do get an estate EIN before filing Form 1041, because the estate is a separate taxpayer.
- Don’t assume your state copies federal rules, because state income and estate taxes vary widely.
- Don’t report income twice across the 1040 and 1041, since that invites an IRS notice.
- Don’t miss April 15 hoping death delays it, because penalties keep accruing.
- Don’t mail to the wrong IRS address, as it adds weeks to a refund.
- Don’t throw away the death certificate, since the IRS or a bank may ask for it later.
Pros and Cons of Each Filing Path
- Pro — surviving spouse joint return: lowest tax and simplest process, because no extra refund form is needed.
- Pro — court-appointed executor: clear legal authority, so banks and the IRS accept your signature without Form 1310.
- Pro — informal next of kin: you can still file and claim a refund, just with Form 1310 attached.
- Pro — filing on time: you avoid the steep 5%-per-month failure-to-file penalty.
- Pro — getting an estate EIN: it keeps the estate’s income clearly separate from the decedent’s.
- Con — surviving spouse path: it ends after the year of death unless you have a dependent child.
- Con — executor path: probate takes time and money, sometimes thousands in court and legal fees.
- Con — informal next of kin: Form 1310 and paper filing slow the refund.
- Con — Form 1041: a second return means more work and possibly a tax preparer’s fee.
- Con — estate tax (Form 706): when it applies, it is complex and almost always needs a professional.
When to Call a Professional
This article is educational and is not a substitute for advice from a licensed professional about your specific situation. Most simple final returns — wages, a pension, some interest — you can handle yourself or with basic software. But some situations call for a CPA, enrolled agent, or estate attorney.
Get professional help if the estate is large enough to owe federal or state estate tax, if there are business interests or rental property, if multiple states are involved, or if heirs disagree. A CPA can prepare the 1040 and 1041, while an estate attorney handles probate and Form 706. The cost is usually far less than the penalties or lost refunds a mistake can cause.
What to Do Next
- Confirm your role — surviving spouse, court-appointed representative, or informal next of kin.
- Gather records — W-2s, 1099s, the death certificate, and any court appointment papers.
- Prepare the final 1040, marking “Deceased” and the date of death on top.
- Add Form 1310 if you are claiming a refund and are not a spouse or appointed executor.
- Check for Form 1041 — if estate income reaches $600, get an EIN and file it.
- File by April 15, 2026, or request an extension with Form 4868 and pay any tax owed.
- Call a professional if the estate is large, complex, or contested.
FAQs
Who is responsible for filing a deceased person’s tax return?
The surviving spouse or personal representative. For tax year 2025, a spouse files jointly, a court-appointed executor files and signs as personal representative, and if no one is appointed, the next of kin handling the estate files it.
Do I have to file a final tax return for someone who died?
Yes, if the person had enough income to require a return for the year of death. The final 2025 return is due April 15, 2026, and covers income from January 1 to the date of death.
What is Form 1310 used for?
It claims a refund owed to a deceased taxpayer. Use Form 1310 if you are claiming the refund and are not a surviving spouse or a court-appointed representative filing the original return.
Does a surviving spouse need Form 1310?
No. A surviving spouse filing a joint return does not file Form 1310. They sign as the surviving spouse, and the refund is issued without the extra form.
What is the deadline to file a deceased person’s final return?
April 15, 2026 for someone who died during 2025. You can extend the filing date to October 15, 2026 with Form 4868, but tax owed still accrues interest from April 15.
How do I sign a tax return for someone who died?
As “personal representative” or “surviving spouse.” Write the role in the signature area, mark “Deceased” and the date of death on top, and attach a court certificate if you were appointed.
What is the difference between Form 1040 and Form 1041?
Form 1040 is the person’s final return; Form 1041 is the estate’s return. The 1040 covers income up to death; the 1041 covers income the estate earns afterward, if it reaches $600.
Will the deceased’s refund come in my name?
Yes, if you properly claim it. A spouse or executor receives it through the return; an informal claimant receives a check in their own name after filing Form 1310.
Does my state require a separate return for a deceased person?
It depends on your state. States with income tax usually require a final state return; Texas, Florida, and Washington have none. Check your state revenue agency’s deceased-taxpayer page.
Do most estates owe federal estate tax?
No. For 2025, federal estate tax (Form 706) applies only to estates above $13.99 million, so fewer than 0.1% of estates owe it. Income tax returns are far more common.
What happens if no one files the deceased’s return?
The IRS can assess tax, penalties, and interest against the estate, and any refund is lost after the claim window closes. Filing protects the estate and releases money owed to the family.
Can I e-file a return for a deceased taxpayer?
Sometimes. A joint return with a surviving spouse often e-files fine. Many returns requiring Form 1310 or a court certificate must be paper-filed, which takes about six weeks or longer to process.
