Capital Gains Tax on Inherited Property in California (2026)

If you've inherited a California home and you're thinking about selling, the question that keeps coming up is whether you'll owe a big capital gains tax bill on the sale. The answer for most heirs is good news: usually very little, sometimes none at all, thanks to a piece of tax law called the stepped-up basis.

Here's how it actually works in 2026, plain English, with the exceptions you should know about.

The stepped-up basis, in plain English

When you buy a house, the price you pay is your "basis." When you sell, you pay capital gains tax on the difference between the sale price and your basis.

When you inherit a house, your basis isn't the original purchase price. Your basis is the fair market value of the house on the date the previous owner died. This is called the stepped-up basis.

Here's why it matters. Say your father bought a home in San Mateo in 1985 for $180,000. When he passed away in 2026, the home was worth $1.6 million. You inherit it.

Under the stepped-up basis rule:

• Your basis is $1.6 million (the value at his death), not $180,000 (the original purchase price).
• If you sell the house six months later for $1.65 million, your taxable gain is $50,000, not $1.47 million.
• The 40 years of appreciation under your father's ownership is completely tax-free to you.

This is the single most important tax rule for inherited property.

How to determine the stepped-up basis value

The basis is the fair market value on the date of death. You need documentation to support this number when you sell. Three common ways:

1. Date-of-death appraisal. A licensed appraiser provides a written valuation as of the date of death. This is the most defensible documentation. It costs $400 to $700 in California.

2. Probate referee appraisal. If the estate goes through probate, the court-appointed probate referee provides an appraisal as part of the inventory. This appraisal can also serve as the basis for capital gains purposes.

3. Comparable sales documentation. For estates that don't go through formal probate (transferred via living trust, joint tenancy, etc.), you can document the value with a list of comparable sales from the date-of-death period. Less defensible than an appraisal but acceptable for smaller estates.

Get this documentation early. The longer you wait, the harder it is to establish the date-of-death value accurately.

The 6-month alternative valuation date

If the property dropped in value in the months after the death (a market crash, fire damage, anything), the executor can elect to use the alternative valuation date of 6 months after death instead of the date of death itself.

This only applies if the alternative valuation reduces the total estate value AND reduces the federal estate tax owed. It can't be used purely to lower capital gains for the heirs.

In practice, this election is rarely used because most estates aren't large enough to owe federal estate tax. But it's worth knowing about.

Capital gains tax rates in 2026

If you do owe capital gains on an inherited California property, the rates are:

Federal long-term capital gains (held more than one year):

• 0% if your taxable income is below $48,350 (single) / $96,700 (married filing jointly)
• 15% if your income is $48,350 to $533,400 (single) / $96,700 to $600,050 (married)
• 20% above those thresholds

Note: inherited property is automatically treated as long-term for capital gains purposes, regardless of how long you've actually held it.

California state capital gains are taxed at your regular state income tax rate, which ranges from 1% to 13.3% depending on income. There's no special preferential rate.

3.8% Net Investment Income Tax applies to higher-income taxpayers (income above $200K single / $250K married).

A Bay Area heir with $200K in taxable income who realizes $50,000 of taxable gain on an inherited home would pay roughly:

• Federal: $7,500 (15%)
• California: $4,650 (9.3%)
• Total: about $12,150

Not zero, but a fraction of what it would be without the stepped-up basis.

The exceptions: when you actually do owe significant tax

Four situations where heirs end up with bigger tax bills than they expected:

1. The home appreciates significantly between death and sale

The stepped-up basis is the value at death. If you hold the home for two years and the market goes up 20%, you owe capital gains on that 20%.

This is why many California heirs sell soon after inheritance. Holding the property is essentially a bet on continued appreciation, and the bet costs you in capital gains when you eventually do sell.

2. You convert it to a rental

If you rent out the inherited home for a few years before selling, you have to recapture any depreciation you took as a rental, and you may also owe higher taxes if it's no longer your primary residence.

3. You make significant improvements

Money spent on capital improvements (additions, major remodels) gets added to your basis, but money spent on repairs and maintenance does not. Keep documentation.

4. The estate tax exemption is exceeded

For very large estates above $13.99M (2026 federal exemption), there's federal estate tax separate from your capital gains. This is rare for typical Bay Area estates but possible for high-value Marin or Atherton properties.

What about the primary residence exclusion?

If you move into the inherited home and live in it as your primary residence for at least 2 of the next 5 years, you can use the standard $250,000 (single) / $500,000 (married) primary residence exclusion when you eventually sell.

This is on top of the stepped-up basis. Combined, it can mean very large gains are completely tax-free.

The trade-off: you have to actually live in the property for 2 years. For heirs who live elsewhere, this rarely applies.

Property tax considerations (Prop 19)

A quick note on California property taxes (a different tax from capital gains):

California Proposition 19 (2021) changed the rules for inherited property. Children inheriting their parents' home generally lose the parents' low Proposition 13 property tax basis, EXCEPT when the child uses the inherited home as their own primary residence within one year, AND files for the homeowners' exemption.

This matters because losing the parents' Prop 13 basis can dramatically increase property tax. A San Mateo home assessed at $200,000 under the parents' basis might reassess to $1.6 million market value when inherited, taking annual property taxes from $2,400 to $19,200.

This is a major reason California heirs decide to sell rather than keep inherited homes. The carrying cost gets much higher overnight.

How a cash sale fits

When heirs sell shortly after inheritance, the gain is usually small (the property hasn't appreciated much in the months between death and sale), and the capital gains tax bill is modest.

This is the cleanest path. We close fast. The proceeds get distributed to heirs. The tax filing the following spring is straightforward.

If you're considering whether to keep, rent, or sell an inherited California home, the capital gains math usually favors selling sooner rather than later, especially if Prop 19 reassessment is going to push your property tax bill way up.

What to do next

This blog post is a general explainer, not personal tax advice. For your specific situation:

1. Talk to a CPA or tax attorney about your specific basis, holding period, and capital gains exposure. Initial consultations are usually $200 to $400.
2. Get a date-of-death appraisal as soon as possible after the death. The longer you wait, the harder it is to defend the value.
3. Get a cash offer from us so you can compare against any traditional listing path. We close fast, which keeps any post-inheritance appreciation (and resulting capital gains) minimal.
