Under the tax code of the United States, when a person (the beneficiary) receives an asset from a giver (the benefactor) after the benefactor dies, the asset often receives a stepped-up basis, which is its market value at the time the benefactor dies (Internal Revenue Code § 1014(a)).

How do you determine the basis of an inherited property?

The basis of an inherited home is generally the Fair Market Value (FMV) of the property at the date of the individual’s death.
