Inherited property usually gets a stepped-up basis, so you may owe far less than you fear. But appreciation after death, a rental with reset depreciation, or selling among siblings can still create a taxable gain. This is where the tax actually lands.
By Hans Goldstein, EA · Updated
Inheriting a home, second home, or rental in California raises an immediate question: what will the IRS take when you sell it? In many cases the stepped-up basis wipes out decades of appreciation. What happens after the date of death is where it gets complicated.

Go deeper: what heirs owe when they sell inherited property on Big Sale Tax.
When you inherit property, your basis is generally reset to its fair market value on the date of death. All the appreciation during the deceased owner's life is wiped out for income-tax purposes. Sell soon after, and the taxable gain may be small or zero.
The short answer: on a $1.35 million sale of a house stepped up to $1.2 million, the taxable gain is $82,500, not the $1.1 million that the parents' old purchase price would suggest. Hypothetical numbers, for illustration only.
Assumptions: the parents bought the house in 1985 for $180,000. Its fair market value on the date of death was $1,200,000 (an appraisal), so that is the heir's basis. The heir is single, sells 14 months later, and pays 5% in selling costs.
| Line | Using the step-up (correct) | Using the parents' old basis (mistake) |
|---|---|---|
| Sale price | $1,350,000 | $1,350,000 |
| Selling costs (5%) | −$67,500 | −$67,500 |
| Basis | −$1,200,000 | −$180,000 |
| Taxable gain | $82,500 | $1,102,500 |
| Federal tax at 15% | $12,375 | not applicable |
| California tax at an assumed 9.3% bracket | $7,673 | not applicable |
| Total, approximate | about $20,000 | the gain is overstated by $1,020,000 |
Why 15% federal: in 2026 the 15% long-term rate applies to a single filer with taxable income from $49,450 to $545,500 (IRS Rev. Proc. 2025-32, checked October 18, 2026). The example assumes total taxable income stays in that range and below the 3.8% net investment income tax threshold. The 9.3% California rate is an assumed bracket, not a guess about your return: California taxes the gain as ordinary income, from 1% up to 13.3%, so use your own bracket. The step-up and its date-of-death value come from IRC §1014 and IRS Publication 523. Get the appraisal at the date of death; it is the number everything else rests on. To test your own sale, use the capital gains tax calculator (2026) for a property sale.
The short answer: if you move into the inherited house and live there for two years before selling, up to $250,000 of gain ($500,000 on a joint return) can be excluded from tax. It matters when the house keeps appreciating after you inherit it.
| Same house, same step-up to $1,200,000 | Sell within a year, never live there | Live there 3 years, then sell |
|---|---|---|
| Sale price, 5% costs | $1,350,000, $67,500 | $1,800,000, $90,000 |
| Gain over the $1,200,000 basis | $82,500 | $510,000 |
| §121 exclusion (single) | none (not eligible) | −$250,000 |
| Taxable gain | $82,500 | $260,000 |
| Federal tax at 15% (same assumptions as above) | $12,375 | $39,000 (without the exclusion: $76,500) |
In the second column the exclusion removes $37,500 of federal tax at the 15% rate, plus the California tax on the same $250,000. Hypothetical numbers; a house that does not appreciate after death produces almost no gain whether or not you move in.
The short answer: Prop 19 changes the property tax on an inherited California home. It does not change the income-tax step-up or the capital gain you report when you sell.

When inherited property has appreciated meaningfully (or was a rental), a structured installment sale under IRC §453 can spread that gain over years. That is useful when multiple heirs want to convert the property to income rather than take a lump-sum tax hit, or when one heir buys out the others.
Most inherited-property sellers owe less than they expect thanks to the step-up, but post-death gains, rentals, and multi-heir sales create real tax. Know your stepped-up basis before you sell, and have a deferral plan ready if there's a gain.
Often very little, because inherited property receives a stepped-up basis equal to its value on the date of death. You generally only owe capital gains tax on appreciation that occurs after you inherit it. California taxes any gain as ordinary income up to 13.3%.
The basis is 'stepped up' to the fair market value of the property on the date of the previous owner's death (or an alternate valuation date). This erases the appreciation during the deceased owner's lifetime for income-tax purposes.
There is no deadline, but the longer you hold it, the more post-death appreciation can accrue and become taxable. Selling soon after inheriting, when the value is closest to the stepped-up basis, usually minimizes the gain.
Each heir generally reports their share of any gain based on their ownership interest. How title is held and how the sale (or a buyout among siblings) is structured affects each person's tax, so plan before the sale.
Yes, if you own it and live in it as your main home for at least 2 of the 5 years before the sale. Then up to $250,000 of gain ($500,000 on a joint return) is excluded. The years the person who died lived there do not count toward your two years, except for a surviving spouse who has not remarried.
No. Prop 19 changes California property tax reassessment, not income tax. You still get the date-of-death step-up in basis, and you report any gain above it when you sell.
Yes. If the inherited property has gained value after death, or was a rental, a structured installment sale under IRC §453 can spread the taxable gain over several years instead of recognizing it all at once.
