Step-Up in Basis
Step-up in basis resets an inherited asset's cost basis to its fair market value at the owner's death, potentially erasing deferred capital gains for heirs.
Definition
Step-up in basis is a provision that adjusts the cost basis of an inherited asset to its fair market value on the date of the owner's death. For real estate investors, it is the capstone of a lifelong 1031 strategy often summarized as swap till you drop.
Because a 1031 exchange only defers tax, carrying a low basis forward through each exchange, an investor who keeps exchanging can build up a large embedded gain. At death, the step-up resets basis to current value, and that deferred capital gain and depreciation recapture generally disappear for the heirs. If a property with a $200,000 adjusted basis is worth $1 million at death, the heirs' basis becomes $1 million, and they could sell with little or no taxable gain.
This makes DSTs and 721/UPREIT structures attractive for estate planning, since fractional interests can be divided among heirs, each receiving a stepped-up basis.
