Inherited assets get a new basis equal to the date-of-death value. Sell soon after and there is almost no gain. Wait ten years and the gain is yours. Most of the tax on inherited property comes from not knowing which assets got the step-up.

Parent's house worth $900,000 at death (basis stepped up), sold 18 months later for $980,000, single heir, 2026
| Layer | Rate (source below) | Amount |
|---|---|---|
| Gain after step-up and selling costs (about $30K) | 15% | about $4,500 |
| Net investment income tax | 3.8% if MAGI over $200K | about $1,100 |
| State (varies) | small | |
| Total | under $6,000 on a $980,000 sale |
Rounded, illustrative. Assumes the heir's other income already puts the gain in the 15% band (2026 brackets, IRS Rev. Proc. 2025-32); with little other income part or all of it is taxed at 0%. See Sources and review at the bottom of the page.

Common questions
Not income tax on the inheritance itself. Tax applies to gain after the date of death, and to withdrawals from inherited retirement accounts.
A revocable living trust: yes. An irrevocable trust funded years ago: usually no. Ask.
Your half stepped up; his did not. Selling now taxes his gain; his passing later steps up his half.
Essentially yes: basis equals the date-of-death value, so only movement since then is taxed.
