If you're worried about a huge tax bill for selling an inherited house, this is the concept that usually calms things down. It's called 'stepped-up basis,' and it often means you owe little or no capital-gains tax when you sell — even on a home that's worth far more than the person paid for it decades ago.
When you inherit a home, your tax 'basis' — the number the IRS measures your gain against — is usually reset ('stepped up') to the home's fair market value on the date the owner died, not what they originally paid.
Because the step-up is pegged to the value on the date of death, it's worth documenting that value — often with an appraisal or a broker's opinion of value ordered for that date. If you sell a year later for more, you only owe tax on the increase since the date of death, which is usually modest.
Stepped-up basis is a federal concept, but your state may treat the sale differently, and everyone's situation has wrinkles. This is general information, not tax advice — a quick conversation with a tax professional about your specific numbers is always worth it, and we can point you to one.
The inheritance itself is generally not income to you. What can be taxed is the gain if the home rises in value after you inherit it and you then sell — measured from the stepped-up basis, not the original purchase price.
It's strongly recommended. A date-of-death appraisal documents your stepped-up basis, which protects you if the IRS ever questions the gain you reported on a sale.
