Filing jointly is enough, IF you and your spouse both meet the "use test." That means you both lived in the house as your primary residence for at least two of the five years leading up to the date of sale. Here is the IRS rule:
You can exclude up to $500,000 of the gain on the sale of your main home if all of the following are true.
1. You are married and file a joint return for the year.
2. Either you or your spouse meets the ownership test.
3.
Both you and your spouse meet the use test d
uring the 2-year period ending on the date of the sale.
4. During the 2-year period ending on the date of sale, neither you nor your spouse excluded gain from the sale of another
home.
