What is a step-up in basis?

Quick Answer

Step-up in basis resets the cost basis of an inherited asset to its fair market value on the date of death. The heir owes no capital gains tax on appreciation during the deceased's lifetime — saving up to 23.8% federal tax on highly appreciated assets.

Step-up in basis example — inherited stock.
