If a Widow Sells Within Two Years, She May Still Get the Married Couple’s $500,000 Home Sale Tax Break

The day a spouse dies, a federal tax clock begins, and many widows do not realize it is running until a valuable tax break is already out of reach.

People often tell a newly widowed spouse not to make any major decisions for a year, and that advice can be wise. But if the surviving spouse owns a home, another deadline starts on the date of death. If the home is sold within two years, the widow or widower can still claim the married couple’s $500,000 home-sale exclusion. After that period ends, the exclusion drops back to the $250,000 amount available to single filers.

A $500,000 Exclusion That Can Survive a Death

The home-sale exclusion allows taxpayers to leave the profit on a primary residence out of taxable income. The profit, or gain, is generally the sale price minus basis. Basis is usually the IRS’s measure of what was paid for the home, plus eligible improvements. To qualify, taxpayers normally must own and live in the home as a principal residence for at least two of the five years before the sale. Single filers can exclude up to $250,000, while married couples filing jointly can exclude up to $500,000.

A special provision lets an unmarried surviving spouse keep the higher $500,000 exclusion if the sale happens no later than two years after the death and the couple met the joint requirements immediately before the spouse died.

Where the Rule Appears in Tax Law

The rule is found in 26 U.S.C. § 121(b)(4), which is titled “Special rule for certain sales by surviving spouses.” IRS Publication 523 says four conditions must be met: the sale must occur within two years of the spouse’s death, the surviving spouse must not have remarried before the sale, neither spouse can have used the exclusion on another home sale within two years of this sale, and the ownership and use tests must be satisfied, with the deceased spouse’s holding period allowed to count.

Who Qualifies and Who Misses Out

The survivor must be unmarried on the closing date. The higher exclusion applies if, just before death, either spouse met the ownership test and both spouses met the residence test. Remarrying before the sale ends the benefit. Missing the two-year deadline by even one day reduces the exclusion to $250,000, assuming the survivor otherwise qualifies on their own. Taking time to grieve does not necessarily forfeit the benefit, but waiting too long can.

How Much the Deadline Can Matter

The value of the two-year window depends on basis, which changes at death. In common-law states, the deceased spouse’s share of a jointly owned home usually receives a new basis equal to fair market value on the date of death, while the survivor’s share keeps its old basis. In community property states — Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington and Wisconsin — the entire home generally receives a stepped-up basis under 26 U.S.C. § 1014(b)(6), so long as at least half of the community interest is included in the deceased spouse’s estate.

Consider this example. A couple bought a home for $200,000 decades ago. They owned it as joint tenants in a common-law state, and the home was worth $1.2 million when the husband died. If she sells for that same amount and ignores selling costs, her new basis is $700,000, leaving a $500,000 gain.

If she sells within the two-year window, she can exclude that entire gain. If she sells after the window closes, $250,000 becomes taxable.

The same home in a community property state would generally receive a $1.2 million basis, leaving no gain at all, so the exclusion would matter far less. That distinction is especially important for long-term owners in common-law states, where home prices have continued climbing. The Case-Shiller index reached 337.3 in July 2026, a five-year high and 1.9% above the prior year.

That two-year deadline is one of several IRS rules that can quietly cost retirees six figures if they are overlooked. Nine such rules are mapped in a free report: The Retiree’s Tax Trap Map.

Filing Status Follows a Different Timeline

For the year a spouse dies, the survivor may still file a joint return if they do not remarry before year-end. For the next two years, some taxpayers can file as a qualifying surviving spouse, which preserves joint tax rates. That status is available only if the home is the principal residence of a dependent son, daughter, stepson or stepdaughter. This filing-status rule is measured in tax years, while the home-sale rule is measured from the date of death. Survivors often confuse the two.

What to Do Before Putting the Home on the Market

1. Document the home’s date-of-death value, preferably with a professional appraisal, because that figure sets the new basis.
2. Mark the deadline clearly: the second anniversary of the spouse’s death.
3. Keep records of home improvements, since they can increase basis.
4. Consult a tax professional before listing the property if the potential gain is substantial.

A Date Worth Remembering

Grief may call for a year of patience, but before that year passes, it is wise to note the second anniversary of a spouse’s death. A sale completed by then can shield as much as $500,000 of gain. A sale completed after that point limits the exclusion to $250,000.
