If you are a surviving spouse or executor handling a 2025 final return, Form 1310 is the IRS form that may be needed to claim the refund in the right name. This guide explains when the form is required, when it is not, what to attach, and how refund claims work for a deceased taxpayer’s final federal return. It is general educational information, not personalized tax advice.
Quick takeaways
- Form 1310 is used to claim a refund on behalf of a deceased taxpayer.
- If a surviving spouse files an original or amended joint return with the decedent, the IRS says Form 1310 is not required.
- If a court-appointed or certified personal representative files the decedent’s original return and attaches the court certificate, Form 1310 is not required for that original refund claim.
- For a 2025 calendar-year decedent, the final return is generally due April 15, 2026.
- The IRS says do not attach a death certificate to the final return; keep it for your records instead.
Who this applies to
This article applies to individual taxpayers and the people who handle a deceased person’s final federal income tax return, especially executors, administrators, surviving spouses, and other family members. Publication 559 is the IRS’s main guide for personal representatives, and the IRS directs families to use it for final-return filing and refund claims. This article is federal-only; state refund claims can follow different rules and forms.
Introduction
When someone dies, tax filing does not stop. The person’s final Form 1040 or Form 1040-SR still has to be filed for income earned up to the date of death, and if that return shows a refund, the IRS wants the right person to claim it. For tax year 2025, that final return is generally due in the 2026 filing season, usually April 15, 2026 for a calendar-year taxpayer.
The key question is not just whether there is a refund. It is who has legal authority to claim the refund and whether Form 1310 is needed. The answer depends on whether you are the surviving spouse, a court-appointed personal representative, or someone else handling the decedent’s property.
What Form 1310 is
Form 1310, Statement of Person Claiming Refund Due a Deceased Taxpayer, is the IRS form used to claim a refund for someone who has died. In plain English, it tells the IRS who is asking for the refund and why that person is allowed to receive it. The IRS’s Form 1310 page says exactly that: use Form 1310 to claim a refund on behalf of a deceased taxpayer.
Form 1310 matters because a refund on a deceased person’s final return does not always belong to the same person who prepared the return. The IRS distinguishes between:
- the decedent’s final return on Form 1040 or Form 1040-SR, and
- the estate’s return on Form 1041, which is a separate taxable entity after death.
That separation is important. A refund reported on the final Form 1040 may belong to the surviving spouse, the estate, or another legally authorized person, depending on who is filing and what documentation is attached.
Who files the final return, and who can claim the refund
The final return is usually filed by the personal representative or surviving spouse
The IRS says the decedent’s final return is generally prepared the same way it would have been if the person were alive, except that it reports income only through the date of death. A personal representative—which usually means the executor or administrator—must file the final return for the year of death and any prior years that were not filed. A surviving spouse can also file the joint return for the year of death in certain situations.
The refund may be claimed in three common ways
- Surviving spouse filing a joint return. If you are the surviving spouse and you file an original or amended joint return with the decedent, the IRS says you do not need Form 1310.
- Court-appointed or certified personal representative filing the original return. If you are the court-appointed or certified personal representative and you file the decedent’s original return, you do not need Form 1310 if you attach the court certificate showing your appointment.
- Other person claiming the refund. If you are not filing a joint return as the surviving spouse and there is no personal representative appointed, the IRS says file the return and attach Form 1310.
When Form 1310 is required and when it is not
| Situation | Need Form 1310? | What to attach or do |
|---|---|---|
| Surviving spouse files an original or amended joint return with the decedent | No | File the final joint Form 1040 or Form 1040-SR. |
| Court-appointed or certified personal representative files the decedent’s original return | No | Attach the court certificate showing appointment. |
| Personal representative files a refund claim on Form 1040-X or Form 843 | Yes, usually | Attach Form 1310 and the court certificate, even if the certificate was already sent before. |
| No surviving spouse and no appointed personal representative | Yes | File the final return and attach Form 1310. |
How to file Form 1310 with the final return
The IRS wants the final return and refund claim to be filed carefully so it can process the refund without delay.
1) Write the decedent’s information on the return
The IRS says to write “DECEASED,” the decedent’s name, and the date of death across the top of the final return. If a joint return is being filed, put both names and the address on the return as instructed.
2) Sign the return correctly
- If a personal representative has been appointed, that person must sign the return.
- If it is a joint return, the surviving spouse must also sign it.
- If no personal representative has been appointed, the surviving spouse filing jointly signs and writes “Filing as surviving spouse.”
- If there is no personal representative and no surviving spouse, the person in charge of the property signs as personal representative.
3) Attach the right proof of authority
If you are a court-appointed personal representative, attach the court certificate showing your appointment. The IRS says a power of attorney or a copy of the will is not acceptable proof of appointment.
4) Do not attach a death certificate to the final return
The IRS says not to attach the death certificate or other proof of death to the final return. Keep it with your records in case the IRS asks for it later.
Deadlines and timing for a 2025 final return
For a calendar-year decedent, the final return is generally due on the same date the return would have been due if death had not occurred. For tax year 2025, that means the final return is generally due April 15, 2026. If that date falls on a weekend or legal holiday, the next business day is timely. The IRS also says a personal representative may obtain an extension on behalf of the decedent.
That deadline matters for refund claims too. A refund should be claimed with the final return whenever possible, because waiting can make the paperwork more complicated, especially if a personal representative has not yet been appointed.
If the final return claims the earned income tax credit (EITC) or the additional child tax credit (ACTC), the IRS says it cannot issue the full refund before mid-February. That delay applies to the entire refund, not just the credit portion.
How the final return differs from the estate return
This is a common source of confusion. The decedent’s final return covers income up to the date of death. After death, the estate becomes a separate taxable entity, and income received after death generally goes on Form 1041 rather than the final Form 1040. The IRS explains that an estate comes into existence at death and is taxed separately from the decedent.
That means a refund, a 1099, or a payment that arrives after death does not automatically belong on the final return. It depends on what the payment represents, when it was earned, and whether it belongs to the estate, the surviving spouse, or another beneficiary. If that line is blurry, the IRS guidance is fact-specific enough that a CPA, enrolled agent, or tax attorney can be helpful.
Common mistakes and a quick myth-vs-fact check
Myth: You always need Form 1310 if the taxpayer died. Fact: You do not need Form 1310 if you are the surviving spouse filing a joint return, or if you are a court-appointed or certified personal representative filing the original return with the court certificate attached.
Myth: The IRS needs a death certificate attached to the final return. Fact: The IRS says not to attach the death certificate; keep it for your records instead.
Myth: A will or power of attorney proves you are the executor for refund purposes. Fact: The IRS says those documents are not acceptable proof of appointment. Use the court certificate.
Myth: A refund to a deceased taxpayer is always paid to the estate. Fact: It depends on who filed, whether a surviving spouse filed jointly, and whether a court-appointed personal representative is involved.
Practical examples
Example 1: surviving spouse joint refund
Linda’s husband died in 2025. Linda files a joint final return for 2025, and the return shows a $1,840 refund. Because Linda is the surviving spouse filing a joint return with the decedent, the IRS says Form 1310 is not required. She should file the final return, keep her records, and wait for the refund unless the IRS asks for more information. Simplified illustration only.
Example 2: court-appointed executor files the original return
Jamal was appointed executor of his mother’s estate. He files her final 2025 Form 1040 and the return shows a $920 refund. He attaches the court certificate proving his appointment. Because he is filing the original return as a court-appointed personal representative, the IRS says Form 1310 is not needed. Simplified illustration only.
Example 3: no executor appointed yet
Erica’s father died in 2025, and no probate appointment has been made yet. The final return shows a $610 refund, and Erica is the one handling the paperwork. Because there is no surviving spouse filing jointly and no court-appointed personal representative, Erica needs to file the final return and attach Form 1310. Simplified illustration only.
Example 4: amended refund claim later on
A personal representative files the original final return correctly, but later discovers another refundable item and decides to file Form 1040-X. The IRS says that if the personal representative files a refund claim on Form 1040-X or Form 843, they should attach Form 1310 and the court certificate, even if the certificate was previously filed. Simplified illustration only.
Checklist: before you file Form 1310
Use this as a quick filing check.
- Confirm whether you are the surviving spouse or the personal representative.
- Decide whether the return is a joint final return or a separate decedent return.
- Check whether Form 1310 is actually required.
- If you are the court-appointed personal representative, attach the court certificate showing your appointment.
- Do not attach the death certificate to the final return.
- If the return claims EITC or ACTC, expect the refund timing to be slower.
- If a state refund is also involved, check your state revenue department’s rules and forms, since they can differ from federal rules.
FAQ
What does Form 1310 do?
Form 1310 tells the IRS who is claiming the refund for the deceased taxpayer and why that person is allowed to receive it. The IRS says to use it to claim a refund on behalf of a deceased taxpayer.
Do I need Form 1310 if I am the surviving spouse?
Usually no, if you are filing an original or amended joint return with the decedent. The IRS says Form 1310 is not required in that case.
Do I need Form 1310 if I am the executor?
It depends. If you are the court-appointed or certified personal representative filing the original return and you attach the court certificate, Form 1310 is not required. If you are filing a later refund claim on Form 1040-X or Form 843, the IRS says to attach Form 1310 and the court certificate.
Should I attach the death certificate?
No. The IRS says not to attach it to the final return. Keep it with your records instead.
What if the refund check has both names on it?
The IRS says a surviving spouse can return the joint-name check marked “VOID” with Form 1310 and a written request for reissuance. The IRS will issue a new check in the surviving spouse’s name alone.
Will the IRS issue the refund immediately?
Not always. The final return still goes through normal IRS processing, and if the return claims EITC or ACTC, the IRS says it cannot issue the refund before mid-February.
What if I am not sure whether I am the right person to file?
That is a good time to get professional help. The IRS rules turn on legal authority, filing status, and whether the refund belongs to the decedent, the spouse, the estate, or someone else. A CPA, enrolled agent, or tax attorney can help if probate is open, heirs disagree, or the refund claim is more complicated than a standard final return.
Bottom line
For a 2025 deceased taxpayer final return, Form 1310 is the IRS form used to claim the refund when the person filing is not automatically covered by the surviving-spouse or court-appointed personal-representative exceptions. The key questions are who is filing, whether the return is joint, and whether the right proof of authority is attached. For most families, the safest approach is simple: file the final return on time, attach the correct documents, and do not send the death certificate with the return.
What to do next
- Confirm whether you are filing as a surviving spouse, executor/personal representative, or another authorized person.
- Check whether Form 1310 is required for the refund claim.
- Gather the court certificate, the final return, and the decedent’s records before filing.
- If you need to amend the return later, remember that Form 1040-X and Form 843 have special attachment rules.
- If the situation involves probate, multiple heirs, or a state refund, check with a tax professional or your state tax agency before filing.
