How to File Taxes if Your Spouse Passed Away in 2025

I’m very sorry for your loss. Filing taxes after losing a spouse can be challenging both emotionally and practically. Here’s a comprehensive guide to help you navigate this difficult process.

Filing Status Options

If your spouse passed away during 2025, you have specific filing options for your 2025 tax return:

Joint Return Option

You are considered married for the whole year and can choose “married filing jointly” as your filing status for the 2025 tax return. This is true even if your spouse died early in the year. IRS – Publication 501: Dependents, Standard Deduction, and Filing Information Filing jointly often provides the most favorable tax treatment.

By definition, a taxpayer cannot file a joint return with a deceased spouse except for the year of death. This is specified in section 6013(c) and (d) of the Internal Revenue Code. Dawson U.S. Tax Court Opinions: Nadine L. Vichich Dawson U.S. Tax Court Opinions: Nadine L. Vichich

Qualifying Surviving Spouse Status

For the two tax years following the year of your spouse’s death (2026 and 2027), you may qualify for “qualifying surviving spouse” status (formerly called qualifying widow(er)) if:

  • You have a dependent child
  • You pay more than half the cost of keeping up your home
  • You haven’t remarried

This status allows you to use the same tax rates as married filing jointly. As the tax code states, there is a tax imposed on the taxable income of “every surviving spouse (as defined in section 2(a)).” IRC § 1(a)

The death of either spouse ends the joint filing choice, beginning with the first tax year following the year in which the spouse died. However, if you qualify as a surviving spouse and are entitled to the joint tax rates as a qualifying surviving spouse, the choice will not end until the close of the last year for which these joint rates may be used.

How to File a Joint Return with Your Deceased Spouse

When filing a joint return for the year your spouse died:

Important Tax Considerations

Unused Deductions

A deceased taxpayer’s unused deductions—capital or net operating loss deductions or deductions for charitable contributions—must be used on the last tax return of the decedent, or they are forever lost. Dawson U.S. Tax Court Opinions: Nadine L. Vichich This makes it crucial to carefully prepare the final return to maximize available deductions.

Joint and Several Liability

Both you and your deceased spouse may be held responsible, jointly and individually, for the tax and any interest or penalty due on your joint return. This means that if one spouse doesn’t pay the tax due, the other may have to. Or, if one spouse doesn’t report the correct tax, both spouses may be responsible for any additional taxes assessed by the IRS. One spouse may be held responsible for all the tax due even if all the income was earned by the other spouse. IRS – Publication 501: Dependents, Standard Deduction, and Filing Information

Estimated Tax Payments

If you and your spouse made joint estimated tax payments:

If a husband and wife make a joint payment of estimated tax and thereafter one spouse dies, no further payments of joint estimated tax liability are required from the estate of the decedent. The surviving spouse, however, shall be liable for the payment of any subsequent installments of the joint estimated tax. For the purpose of making an amended payment of estimated tax by the surviving spouse, and the allocation of payments made pursuant to a joint payment of estimated tax between the surviving spouse and the legal representative of the decedent in the event a joint return is not filed, the payment of estimated tax may be divided between the decedent and the surviving spouse in such proportion as the surviving spouse and the legal representative of the decedent may agree. Tresuary Reg. 1.6654-2

Determining Marital Status

For the purpose of filing a joint return under section 6013, the status as husband and wife of two individuals having taxable years beginning on the same day shall be determined: (1) If the taxable year of each individual is the same, as of the close of such year; and (2) If the close of the taxable year is different by reason of the death of one spouse, as of the time of such death. Tresuary Reg. 1.6013-4

Practical Steps to Take

  • Gather necessary documents:
    • Your spouse’s Social Security number
    • Death certificate
    • Prior year tax returns
    • All income statements (W-2s, 1099s) for both you and your spouse
    • Records of deductible expenses
  • Determine if you need to file an estate tax return:
    • Form 706 (United States Estate Tax Return) may be required if your spouse’s estate exceeds certain thresholds
    • Due nine months after the date of death
  • Consider professional assistance:
    • The year following a spouse’s death involves complex tax situations
    • A tax professional can help ensure you claim all available benefits and avoid errors
  • Plan for future years:
    • Remember your filing status will change in future years
    • Adjust tax withholding and estimated payments accordingly

Special Situations

If You Remarry in 2025

If your spouse died in 2025 and you remarry before the end of the year:

  • You cannot file jointly with your deceased spouse
  • You must file as married filing jointly or married filing separately with your new spouse
  • If your spouse died during the year and you don’t remarry before the end of the year, you must generally file a joint return to take certain credits. If you do remarry before the end of the year, the credit can be claimed on your deceased spouse’s own return. IRS – Publication 503: Child and Dependent Care Expenses

Estate Considerations

If your spouse had significant assets, there may be estate tax implications:

One’s status as the surviving spouse is crucially important for the application of the Federal estate tax rules. The identification of a decedent’s surviving spouse is a Federal issue that should be determined by applying State law—typically, the law of the State where the decedent’s estate is administered. Dawson U.S. Tax Court Opinions: Estate of Semone Grossman, Deceased, Richard M. Frome, Preliminary Executor

The QTIP (Qualified Terminable Interest Property) regime generally allows a transfer of QTIP to qualify for a marital deduction for the first spouse to die and thereby to escape inclusion in that spouse’s estate, even though only a life interest passes to the surviving spouse. “At the death of the second spouse, QTIP property is taxed as part of the surviving spouse’s estate.” Inclusion in the transfer tax base of the surviving spouse is the quid pro quo for allowing a marital deduction to the estate of the first spouse to die.

Conclusion

Filing taxes after losing a spouse is challenging, but understanding your options can help you make the best financial decisions during this difficult time. For the year of your spouse’s death (2025), you can generally file a joint return, which often provides the most favorable tax treatment. For the following two years, you may qualify for the qualifying surviving spouse status if you meet certain requirements.

Remember that tax laws are complex, and individual situations vary. Consider consulting with a tax professional who can provide guidance specific to your circumstances and help ensure you receive all the tax benefits available to you during this transition.
