When someone dies, the Internal Revenue Service (IRS) must be notified. The executor is responsible for notifying the IRS.
Notification deadline: Final return due by April 15 of the year following death (standard filing deadline); Form 56 should be filed as soon as a fiduciary is appointed.
Steps to take
Steps for notifying the IRS and applying for survivor benefits:
1
File the deceased person's final income tax return (Form 1040):
- •Report income from January 1 to the date of death
- •Write "DECEASED," the decedent's name, and date of death across the top of the return
- •If filing jointly, the surviving spouse signs the return and writes "Filing as surviving spouse" next to their signature
- •Due by April 15 of the year following the year of death
2
Obtain an Employer Identification Number (EIN) for the estate if the estate has income:
- •Apply online at irs.gov/ein
- •An EIN is required to open an estate bank account and file estate income tax returns
- •Do not use the deceased person's Social Security number for estate transactions
3
File Form 56 (Notice Concerning Fiduciary Relationship) to notify the IRS that a fiduciary (executor or administrator) has been appointed for the estate.
4
File estate income tax return (Form 1041) if the estate has gross income of $600 or more:
- •Report income earned by the estate after the date of death
- •Also required if any beneficiary is a nonresident alien, regardless of income amount
- •File annually until the estate is fully distributed
- •Due by April 15 of the year following the tax year (calendar year estates)
5
File estate tax return (Form 706) if the gross estate exceeds the federal exemption:
- •Federal estate tax basic exclusion amount: $13.99 million per individual for 2025 deaths; $15.0 million for 2026 deaths (per Rev. Proc. 2025-32 and the One, Big, Beautiful Bill)
- •Due within 9 months of the date of death (6-month extension available)
- •Required even if no tax is owed when electing portability of the unused exemption to a surviving spouse
6
Request tax transcripts for prior years if needed by filing Form 4506-T (Request for Transcript of Tax Return).
7
Consider filing Form 4810 (Request for Prompt Assessment) to shorten the assessment period to 18 months, allowing the estate to close sooner.

Survivor benefits
Surviving Spouse Filing Status
A surviving spouse can file a joint return with the deceased for the year of death, which typically results in a lower tax liability. For the two tax years following the year of death, a qualifying surviving spouse with a dependent child may use the Qualifying Surviving Spouse filing status.
Eligibility: Surviving spouse of the deceased taxpayer
How to apply: Select the appropriate filing status when filing the federal income tax return
Learn more →Refund for Deceased Taxpayer
If the deceased is owed a federal tax refund, the executor, administrator, or surviving spouse can claim it by filing the final return. Form 1310 (Statement of Person Claiming Refund Due a Deceased Taxpayer) must be attached unless the filer is a surviving spouse filing a joint return or a court-appointed personal representative who attaches a copy of the court certificate.
Eligibility: Executor, administrator, or surviving spouse
How to apply: File the final Form 1040 and attach Form 1310 if required; court-appointed representatives attach a copy of court appointment documentation instead

Yes. A final income tax return (Form 1040) must be filed for the deceased for the year of death. The executor, administrator, or surviving spouse is responsible for filing. The return covers income from January 1 to the date of death.
Yes. A surviving spouse can file a joint return with the deceased for the tax year in which the death occurred. This often results in a more favorable tax rate. The surviving spouse signs the return and writes "Filing as surviving spouse" next to their signature.
The federal estate tax basic exclusion amount is $13.99 million per individual for decedents dying in 2025, and $15.0 million for decedents dying in 2026. Estates valued below this threshold generally do not owe federal estate tax. The exemption is adjusted annually for inflation.
An EIN (Employer Identification Number) is needed if the estate has income, opens a bank account, or files an estate income tax return (Form 1041). Apply online at irs.gov/ein. Do not use the deceased person's Social Security number for estate transactions.
Form 706 (estate tax return) is due 9 months after the date of death. A 6-month extension is available by filing Form 4768. Even with an extension, any estimated estate tax owed must be paid by the original due date to avoid penalties.
File the deceased person's final Form 1040. If you are not a surviving spouse filing a joint return and not a court-appointed personal representative, attach Form 1310 (Statement of Person Claiming Refund Due a Deceased Taxpayer). Court-appointed representatives attach a copy of their court certificate instead. The refund will be issued to the estate or the person who filed the return.
Form 56 (Notice Concerning Fiduciary Relationship) notifies the IRS that a fiduciary, such as an executor or administrator, has been appointed for the taxpayer's estate. It authorizes the fiduciary to act on behalf of the deceased in tax matters.
Portability allows a surviving spouse to use the deceased spouse's unused federal estate tax exclusion amount. To elect portability, the executor must file Form 706 within the deadline, even if the estate is below the filing threshold and no tax is owed. Without a timely filed Form 706, the unused exclusion is lost.
There is no specific deadline or formal cancellation process. The IRS does not require a separate death notification for ITIN holders beyond filing the final tax return. Writing to the IRS ITIN Unit with a copy of the death certificate can help prevent potential identity theft.
After completing the notification process, eligible survivors can apply for 2 benefits through the IRS. Each benefit has its own eligibility requirements and application process.
Keep copies of all documents submitted to the IRS. Original documents submitted for verification are typically returned after processing.
