Surviving Spouse
Tax Returns

Filing status in the year of death

The surviving spouse is generally eligible to file jointly for the year of death, regardless of when during the year the spouse passed. A joint return almost always produces the lowest tax and is the most beneficial filing option. The return also serves as the decedent's final 1040. Both sides of the return must be coordinated: income, deductions, and credits for both spouses through the date of death for the decedent and through year-end for the survivor.

If the client has power of attorney for the surviving spouse, the POA agent signs the return on behalf of the surviving spouse. If the client is the executor of the decedent's estate, they may also need to sign as the decedent's representative. We handle the authorization and signature requirements for both roles.

Qualifying surviving spouse status

For the two tax years following the year of death, the surviving spouse may qualify for "qualifying surviving spouse" status if they have a dependent child. This preserves the married filing jointly tax rates and standard deduction for those two years. After that, the survivor moves to single or head of household status, which typically increases the tax liability. This transition should be anticipated in estimated tax planning for those years.

Retirement account decisions

Surviving spouses have options not available to other beneficiaries. The spousal rollover allows the surviving spouse to treat the decedent's IRA as their own, delaying RMDs until their own required beginning date and naming new beneficiaries. This is usually the most advantageous option when the survivor does not need immediate access to the funds.

If the decedent had already begun taking RMDs, the year-of-death RMD must still be taken. Any remaining RMD amount not distributed before the date of death must be distributed by year-end. We coordinate these distributions with the rollover to avoid missed RMDs or excess distributions.

Basis step-up on jointly held assets

Assets held jointly generally receive a step-up in basis on the decedent's half as of the date of death. In community property states, both halves of community property may receive a full step-up. The basis determination affects every future disposition, so it must be documented at the time of death even if no sale is imminent. We calculate and document the new basis for each asset in the portfolio.

DSUE portability coordination

If the decedent's estate did not use the full federal estate tax exemption, the surviving spouse can inherit the unused amount through the DSUE portability election. This requires filing a Form 706 within nine months of death (with extensions), even if no estate tax is owed. The deadline is absolute, and missing it forfeits the election permanently.

If the deadline has already passed, late portability relief may be available under Rev. Proc. 2022-32 for estates that were not otherwise required to file a 706. This is not guaranteed, but it is worth evaluating when the DSUE amount is significant.

Estate income tax (Form 1041)

If the decedent held assets individually, those assets may pass through the estate before reaching the surviving spouse or other beneficiaries. Any income earned by the estate during administration (interest, dividends, capital gains from asset sales) triggers a Form 1041 filing obligation. Distributions to beneficiaries carry out income via K-1s, and the timing and character of those distributions affect both the estate's and the beneficiary's tax liability.
