Sold a house you inherited? Step-up in basis, explained (NEW — added Sat Oct 10)
One of the most common — and costly — misunderstandings I see every year: someone inherits a parent's house, sells it, and assumes they owe capital gains on the difference between the original purchase price and the sale. If a parent bought the home decades ago, that sounds terrifying. Here's the good news: it doesn't work that way.
When you inherit property, your cost basis "steps up" to the fair market value on the date of death. That's the number you start from — not what your parents paid. Sell it shortly after for about that value, and there's often little or no taxable gain. The property being in a revocable living trust doesn't change this — for tax purposes it's treated as the decedent's property, so the step-up still applies.
Three practical points if this applies to you:
Get a date-of-death appraisal (or a solid FMV estimate) as early as you can — that becomes your new basis.
Improvements you pay for after inheriting add to basis, so keep the receipts.
Don't "shortcut" estate planning by being added to the deed while a parent is still alive — a lifetime gift carries over the parent's original basis, and the step-up is lost. That difference can be enormous.
Since a sale like this in 2026 is a current-year filing question, it's worth sorting out before your return — not after.

The step-up in cost basis removes double taxation and helps households with estate values above the estate tax threshold.
