When your spouse passes away, you are generally considered married for the entire tax year for filing status purposes, provided you did not remarry before the end of the year. This means you may file a joint return with your deceased spouse for that year, even if they died during the year. The IRS allows this to ensure continuity in tax treatment and to allow you to claim certain benefits, such as qualifying surviving spouse status for the next two years (if you meet the requirements, such as having a dependent child).
Filing a Joint Return with a Deceased Spouse
If your spouse died during the tax year and you did not remarry, you may file a joint return for that year. This is permitted under IRS rules, as explained in Publication 17 and Publication 501.
To file a joint return:
- On Form 1040, you must:
- Check the “Deceased” box at the top of the form
- Enter the date of death in the space provided
- This applies whether filing for the taxpayer or spouse.
- When e-filing, the software will prompt you to enter the date of death.
The joint return must be signed by you (the surviving spouse). If a personal representative (executor or administrator) has been appointed, that person must also sign the return. If no personal representative has been appointed, the surviving spouse signs and may write “filing as surviving spouse” in the signature area.
When a Separate Return May Be Required
A separate return may be filed instead of a joint return only if you choose not to file jointly or if a personal representative disaffirms the joint return within one year from the filing deadline. You generally cannot switch a joint return to separate returns after the filing deadline.
If a joint return has already been filed, it can generally be changed to separate returns by filing amended returns within the standard amendment period (generally within three years of the original filing deadline), as outlined in Publication 559.
If you choose to file separately, each spouse’s income, deductions, and credits must be reported separately according to IRS rules.
Final Return for the Decedent
A final return must be filed for the decedent if they met the filing requirements at the time of death. The return is prepared the same way as if the person were alive, reporting income from January 1st up to the date of death.
The executor, administrator, or other legal representative is responsible for filing this return.
If the decedent did not meet the filing requirements but had income tax withheld, made estimated tax payments, or is eligible for refundable credits, a return should still be filed to claim a refund. In some cases, a surviving spouse or other claimant may need to file Form 1310 to claim the refund.
Qualifying Surviving Spouse Status
You may be eligible for Qualifying Surviving Spouse status for the two years following your spouse’s death if: You have a dependent child (not just any dependent).
You paid more than half the cost of keeping up a home for the child.
The child lived with you for the entire year (except for temporary absences like school or vacation).
This status allows you to file with the same standard deduction as Married Filing Jointly ($31,500 for 2025).
