Filing taxes for the deceased: final return, estate return, and refund rules

For a 2025 death, the final Form 1040 reports income through the date of death. A personal representative usually files it, and a refund may require Form 1310. Estate income after death can trigger Form 1041, while Form 706 is a separate transfer-tax return.

The following 3 forms separate the main federal filing jobs after a taxpayer dies:

• Final Form 1040 or 1040-SR – reports the decedent’s income from January 1, 2025, through the date of death.
• Form 1041 – reports qualifying income earned by the estate after death; a domestic estate generally files at $600 or more of gross income.
• Form 706 – reports federal estate tax for estates that meet a separate transfer-tax filing rule.

The IRS final-return guidance for someone who has passed away explains signature rules and refund claims.

A surviving spouse filing jointly may not need Form 1310; review TFX’s Form 1310 refund guide for claimant rules.

The IRS also explains how to file the final income tax return of a deceased person.

Based on our client scenario at TFX: a surviving spouse may sign a 2025 joint return without a court appointment. An executor appointed by a probate court signs in a fiduciary role; TFX’s IRS Form 56 guide covers fiduciary notice.

Final return vs. estate return: which tax filing for deceased situation applies?

Three federal returns can apply after a death, but they cover different tax bases. Form 1040 stops at the date of death, Form 1041 covers qualifying estate income after death, and Form 706 addresses estate transfer tax when the applicable filing threshold is met.

The decision rule is simple: start with the final Form 1040, then add Form 1041 for qualifying post-death estate income and Form 706 only when the estate-tax rules require it.

 

The IRS’s estate income tax return guidance treats the estate as a separate taxpayer for post-death income. This distinction matters in filing taxes for deceased with no estate because a final individual return may still be required even when no probate estate opens.

A filing final tax return for deceased case can still require later estate filings if assets earn interest, dividends, rent, or gains after death. TFX’s estate taxes for expatriates guide explains separate transfer-tax rules for US citizens and expats.

The IRS also has separate estate and gift tax return filing guidance. The practical rule is to finish the decedent’s final return first, then identify any income or transfers that belong to the estate.

When do you have to file taxes for a deceased person?

A 2025 final return is required when the decedent met normal filing rules or another filing trigger applied. For example, a single taxpayer under 65 generally files at $15,750 of gross income, while net self-employment earnings of $400 can create a separate filing requirement.

The following 5 checks determine whether filing is required or useful for the year of death:

• Income threshold: filing deceased taxes follows the decedent’s filing status, age, and 2025 gross-income threshold.
• Refund claim: file taxes for deceased when withholding, estimated payments, or refundable credits could produce money back.
• Self-employment: a death tax return may be required when net self-employment earnings reach $400.
• Prior years: file taxes deceased for earlier open years if the decedent should have filed but did not.
• Estate income: post-death income belongs to the estate and may trigger Form 1041 instead of the final individual return.

TFX’s minimum income to file taxes guide gives the 2025 filing thresholds by status.

Read TFX’s filing-requirement guide when income is below the standard threshold, but another IRS rule may still require a return.

Timeline box: The regular due date for a calendar-year 2025 Form 1040 is April 15, 2026. Death does not automatically extend that date, although ordinary filing extensions and special overseas rules can apply.

The IRS Interactive Tax Assistant for a deceased person’s return can help determine the filing path. A final tax return after death may still be worth filing when no balance is due because withholding or estimated payments can create a refund.

 

Who can file taxes for a deceased person?

The filing hierarchy starts with a court-appointed executor or administrator. If none exists, an eligible surviving spouse may file a joint Form 1040, and another person in charge of the property can act as personal representative. Form 1310 rules depend on that legal role.

The following 3 filer categories cover the usual situations:

• Court-appointed executor or administrator: this person signs the final return and attaches proof of appointment when required.
• Eligible surviving spouse: the spouse may file jointly for the year of death and signs as the surviving spouse when no representative is appointed.
• Person in charge of property: if there is no spouse or court appointment, this person may file as personal representative and may need Form 1310 for a refund.

The IRS final federal return guidance for someone who died explains this hierarchy and the signature rules. For an IRS deceased taxpayer case, the legal authority to act matters more than who happens to gather the records.

Filing taxes for a deceased parent does not automatically give an adult child authority to sign. A child can file when appointed by the court or when the child is the person legally in charge of the decedent’s property under the applicable rules.

Based on our client scenario at TFX: a widow filing a joint 2025 return can sign as surviving spouse. An adult child appointed executor signs as executor. If a court names an estate administrator instead, that administrator signs in the fiduciary role.

What documents you need before filing

Start with records that establish the decedent’s identity, authority to file, and 2025 income. The core package usually includes a death certificate, Social Security number, tax forms, and probate papers. Keep post-death estate records separate because they may belong on Form 1041.

The following 6 items are the must-have now records for most cases:

• Death certificate for the file; the IRS generally does not require it with the final Form 1040 unless requested.
• Social Security number and exact legal name of the decedent.
• Will, court appointment, letters testamentary, or other probate authority if applicable.
• 2025 W-2s, 1099s, SSA-1099s, 1099-Rs, and brokerage tax statements.
• Prior-year federal returns and notices for any open tax years.
• Estate EIN documents if an estate account or Form 1041 filing has already been set up.

Use TFX’s tax document checklist to organize wage, retirement, investment, and payment records.

The following 4 records are helpful if available and can reduce follow-up work:

• Bank and brokerage statements showing transactions before and after death.
• Records of estimated tax payments and prior-year carryforwards.
• Receipts for medical costs, charitable gifts, and deductible expenses.
• Foreign income, pension, and account records for a taxpayer who lived or held assets abroad.

For taxpayers without a local personal tax return, see TFX’s US tax document guide for no-tax-return countries.

Keep post-death interest, dividends, rent, and sale proceeds in a separate estate folder. Those amounts may belong to Form 1041 even when they come from an account that was originally owned by the decedent.

What to do first after someone dies

The first 48 hours should focus on protecting records and identifying who has authority to act, not preparing a tax return. Five early actions can prevent income, refund, and estate records from being mixed. Most taxes after death are handled later, once legal authority and records are clear.

The following 5 actions should be completed or started before return preparation:

1. Secure tax records – tax action. Collect prior returns, wage forms, account statements, IRS notices, and login details that the authorized representative can lawfully access.
2. Notify employer and financial institutions – administrative action. Ask what death documentation they require and how future tax forms will be issued.
3. Identify the personal representative – legal/administrative action. Confirm whether a will names an executor or a court must appoint an administrator.
4. Review direct deposits – administrative action. Do not redirect or spend deposits until the bank or payer confirms what the authorized representative may do.
5. List open tax years – tax action. Note the 2025 final return plus any prior years that appear unfiled or unresolved.

First 48 hours mini-box: Secure the decedent’s records, stop unauthorized account access, and identify the person who can legally act. Do not combine pre-death and post-death income simply because both arrive in the same calendar year.

The return itself usually comes later. The early goal is to preserve a clear record of the date of death, who has authority, and which income belongs before versus after that date.

Tax refund deceased: who gets the refund and when Form 1310 applies

A refund goes to the person or estate legally entitled to claim it, not automatically to the nearest relative. Form 1310 usually applies to another claimant. A surviving spouse filing jointly and a court-appointed representative filing the original return can qualify for exceptions.

The following 3-step decision tree determines the usual Form 1310 path:

1. Surviving spouse filing an original or amended joint return? Form 1310 is generally not required.
2. Court-appointed representative filing the original return with the court certificate attached? Form 1310 is generally not required.
3. Another claimant or a representative claiming through an amended/refund claim? Review Form 1310 line A, B, or C and attach the required evidence.

The key rule is claimant status: Form 1310 is driven by who claims the refund and what return or refund claim is being filed.

 

The December 2025 Form 1310 changed one point worth checking: a filer who checks line B must attach the court certificate to Form 1310 even if the IRS received that certificate before.

For direct deposit, follow the 2025 Form 1040 account-name rules and confirm the financial institution will accept the refund for the legally entitled claimant. Do not route a refund to a preparer or unrelated person.

If a paper refund or reissued check is involved, use the address and reissue procedure in the current Form 1310 instructions. Once funds are legally available, see TFX’s tax refund guide.

When Form 1041 applies to a deceased person tax return situation

Form 1041 reports income earned by a decedent’s estate after death. For a domestic estate in tax year 2025, filing is required at $600 or more of gross income, with a nonresident alien beneficiary, or when specified QOF reporting requires Form 8997.

Income belongs on the return for the taxpayer that earned or received it: pre-death income generally goes to the final Form 1040, while estate income after death can belong on Form 1041.

 

The 2025 Form 1041 instructions set April 15, 2026, as the deadline for calendar-year estates. A fiscal-year estate files by the 15th day of the 4th month after its year ends.

Based on our client scenario at TFX: an illustrative estate receives $700 of bank interest after death and has no other income. That amount reaches the $600 gross-income trigger, so the fiduciary must evaluate and file Form 1041.

 

 

Inherited retirement accounts can create separate beneficiary reporting questions. TFX’s inherited IRA distribution guide covers post-death beneficiary rules alongside estate-income reporting.

Estate tax vs. income tax: filing a final tax return for deceased is not the same as Form 706

Form 706 is a transfer-tax return, not the decedent’s final income tax return. For deaths in 2025, the federal filing threshold is generally $13.99 million before certain adjustments. For deaths in 2026, the basic exclusion amount is $15 million under current law.

For a 2025 death, most estates below the $13.99 million federal Form 706 filing threshold will deal with income-tax filings instead, although portability or special rules can still make a Form 706 filing relevant.

 

Most people do not need Form 706. The form is generally due within 9 months of death when required, and Form 4768 can provide an automatic 6-month extension to file.

US citizens and US-domiciled residents are subject to the federal estate-tax rules on a broader asset base than nonresident noncitizens. TFX’s federal estate tax guide for foreign investors explains the nonresident side.

Certain nonresident noncitizens must file Form 706-NA when US-situs assets exceed $60,000, subject to treaty rules and other adjustments. The IRS explains when nonresidents with US assets must file estate tax returns.

Deductions, credits, and special items to review before you file taxes for a deceased person

The 2025 final return can still claim deductions and credits allowed through the date of death. Review medical costs, state taxes, charitable gifts, retirement items, income in respect of a decedent, and inherited-property basis. Post-death items may instead belong to the estate or beneficiary.

The following 6 tax items deserve a separate review before the final return is filed:

• Medical expenses: qualifying expenses paid before death follow normal itemized-deduction rules. Certain estate-paid medical expenses within 1 year after death can be elected onto the final return.
• State and local taxes: review deductible taxes paid before death and keep estate-level payments separate.
• Charitable gifts: contributions completed before death may belong on the final return if the deduction rules are met; testamentary gifts follow estate rules.
• Retirement distributions: amounts received before death may be on the final return, while later distributions can belong to a beneficiary or estate.
• Income in respect of a decedent: items such as certain unpaid wages can be taxable to the estate or beneficiary who receives them rather than the cash-basis decedent’s final return.
• Basis adjustment: inherited property generally uses date-of-death fair market value as its basis, subject to statutory exceptions and any valid alternate valuation election.

The IRS’s tax-planning guidance after filing recommends keeping records that support deductions and tax positions. For a deceased taxpayer, separate receipts and statements by date so the final return and estate return do not claim the same item.

The following 3 document groups should be checked before filing:

• Receipts and statements for medical, charitable, and deductible tax payments.
• Brokerage records and appraisals that support inherited-property basis.
• Prior-year returns showing capital-loss, credit, or other carryforward information.

Special cases box: Review foreign accounts, inherited retirement accounts, and year-of-death credits separately. Each can have a reporting rule that does not follow the same timing as ordinary wage income.

When professional help makes sense for deceased tax filing

Outside help is most useful when the return crosses more than 1 tax system or legal role. Missing records, estate income, foreign assets, unfiled years, disputed refunds, or several beneficiaries can turn a final Form 1040 into a coordinated Form 1041, Form 1310, or estate matter.

The following 6 triggers are practical reasons to consider professional preparation:

• Records are missing or prior returns were never filed.
• The estate earned post-death income and may need Form 1041.
• Foreign accounts, pensions, businesses, or investments are involved.
• The refund claimant’s authority is disputed or unclear.
• Several beneficiaries receive income or property from the estate.
• Form 706, Form 706-NA, portability, or treaty issues may apply.

TFX’s guide to hiring an expat tax professional explains when cross-border filing complexity can justify paid help.

If legal representation or privilege matters, compare a tax attorney vs. CPA before choosing the role.

The IRS recommends checking a tax professional’s credentials and PTIN before hiring.

DIY is a better fit when authority and records are clear, and only 1 straightforward final Form 1040 is needed; professional preparation is more useful when several forms, beneficiaries, countries, or unresolved years must be coordinated.

Deceased taxpayer living abroad: extra rules for expats

A US citizen or resident alien who dies abroad still reports worldwide income through the date of death on the final US return. For a 2025 calendar-year return, an eligible taxpayer abroad can receive the automatic filing extension to June 15, 2026, under the overseas rules.

The following 6 cross-border items should be reviewed separately:

• Foreign income: include worldwide income through the date of death on the final Form 1040 when US worldwide-income rules apply.
• Foreign death certificate: keep the local certificate, but the IRS generally does not require a death certificate with the final Form 1040.
• Foreign probate papers: keep the court or notarial documents proving who can act for the estate.
• Translations: keep an accurate English translation available when an IRS form, instruction, or request requires readable supporting evidence.
• Foreign executor: confirm US signature, fiduciary-notice, EIN, mailing, and refund-claim requirements before filing.
• Foreign accounts: review both FBAR and Form 8938 because they use different assets, thresholds, and filing systems.

TFX’s US expat tax guide explains worldwide-income reporting for Americans abroad. That rule remains relevant for the final year through the date of death.

FBAR can apply when a US person’s aggregate foreign financial accounts exceed $10,000 at any time in the calendar year. See TFX’s FBAR vs. Form 8938 guide because the two regimes use different assets and thresholds.

Based on our client scenario at TFX: an illustrative US citizen dies in Spain in September 2025 after earning US investment income and Spanish salary. The final US return includes reportable worldwide income through death, while later estate income is reviewed separately.
