Pub 523:

"Widowed taxpayers.

If you are a widowed taxpayer who doesn't meet the 2-year ownership and residence requirements on your own, consider the following rule. If you haven’t remarried at the time of the sale, then you may include any time when your late spouse owned and lived in the home, even if without you, to meet the ownership and residence requirements."

Of course, they likely meet the 2 year residency requirement on their own. But it continues:

"Also, you may be able to increase your exclusion amount from $250,000 to $500,000. You may take the higher exclusion if you meet all of the following conditions.

  1. You sell your home within 2 years of the death of your spouse;

  2. You haven’t remarried at the time of the sale;

  3. Neither you nor your late spouse took the exclusion on another home sold less than 2 years before the date of the current home sale; and

  4. You meet the 2-year ownership and residence requirements (including your late spouse's times of ownership and residence, if applicable)."
