Capital Gains Tax on Inherited Property

Heirs selling an inherited house or a small inherited rental building in New York are often surprised to learn the tax bill is smaller than they feared, or in some cases nonexistent, because of how the basis resets at death. But that reset isn't automatic in every situation, and estates involving jointly held property, trusts, or a long gap between the date of death and the eventual sale can complicate what looks like a simple rule on paper.

When someone inherits real property, the basis generally resets to the property's fair market value as of the date the original owner died, rather than carrying over what that owner originally paid for it. This means if a parent bought a Bronx two-family house decades ago for a fraction of what it's worth today, and a child inherits it and sells shortly after, the taxable gain is measured from the date-of-death value, not the original purchase price, which can reduce the gain to a small fraction of what it would have been under a carryover basis rule.

The practical challenge is establishing that date-of-death value accurately. A formal appraisal conducted close to the date of death, or a well-documented estate tax filing that includes a valuation, gives the heir defensible support for the basis used on a later sale. Waiting years to sell without ever pinning down that value at the time of inheritance can make this harder to substantiate.

The stepped-up basis only shelters appreciation that occurred before death. If an heir holds the inherited property for several years before selling, and the market continues to rise, the gain accumulated after the date of death is taxable the normal way. A property that sits in an estate for an extended settlement process, or that heirs choose to hold and rent out for a period before eventually selling, can accumulate a meaningful post-inheritance gain even with the stepped-up basis in place.

New York has its own estate tax, separate from the federal estate tax, with a lower exemption threshold than the federal system. An estate that owes New York estate tax is a different issue from capital gains tax on an eventual sale, but the two interact in the sense that the same date-of-death valuation used for the stepped-up basis calculation often needs to match what was reported on any New York estate tax filing, so these two pieces of paperwork should be handled together rather than separately.

An heir who inherits a rental property and wants to reinvest the proceeds into a different asset, rather than take a lump sum after selling, can use a 1031 exchange on the post-inheritance gain the same way any investment property owner would, since the inherited property is treated as newly acquired at the stepped-up basis. This is often relevant for heirs who inherit a management-heavy building, like a multi-unit walk-up requiring hands-on landlord work, and would rather exchange into something more passive than continue operating it directly.
