In most cases, no — or very little. When you inherit a house in California, your cost basis is "stepped up" to the property's fair market value on the date of the decedent's death. If you sell near that value, there is almost no taxable gain, no matter how much the home appreciated during the decedent's lifetime. You are taxed only on appreciation after the date of death.
That single rule is the most valuable and least understood piece of tax law in a California estate sale. This page explains how it works, what it does not cover, and where the real tax exposure actually sits.
This is general information, not tax or legal advice. Confirm your specific situation with a CPA or tax attorney before you sell.
How the Step-Up in Basis Works
Normally, your capital gain is the sale price minus what you paid — your basis. Inherited property is different. Under federal law, the basis of property acquired from a decedent is generally the fair market value on the date of death, or the fair market value on the alternate valuation date if the executor files an estate tax return and elects it. The IRS sets this out in Publication 551, Basis of Assets.
The practical effect on a California home is dramatic, because California homes held for decades often carry a basis from a different era.
| Scenario | Original Purchase (1985) | Value at Date of Death | Sale Price | Taxable Gain |
|---|---|---|---|---|
| Without a step-up (e.g. lifetime gift) | $120,000 | $845,000 | $845,000 | $725,000 |
| Inherited, sold at date-of-death value | $120,000 | $845,000 | $845,000 | $0 |
| Inherited, sold 14 months later, market up | $120,000 | $845,000 | $890,000 | $45,000 |
| Inherited, sold below date-of-death value | $120,000 | $845,000 | $815,000 | $0 (capital loss) |
The $845,000 figure used above is California's current statewide median sale price, per Houzeo's California market data. The point of the table is the second row: the $725,000 of lifetime appreciation simply is not taxed to the heir.
The Gain You Do Owe Tax On
You are taxed on appreciation after the date of death. If the home was worth $845,000 when your parent died and you sell it 14 months later for $890,000, your gain is $45,000 — less selling costs, which include the commission.
Two things determine what that costs you:
Federal. Inherited property gets long-term treatment regardless of how long you personally held it, so the long-term rates apply rather than ordinary income rates. The IRS covers the rate structure in Topic no. 409, Capital gains and losses, and confirms in its gifts and inheritances guidance that the property is treated as long-term.
California. The state does not give capital gains a preferential rate. California taxes capital gains as ordinary income at the same 1%–12.3% bracket structure that applies to wages, per the Franchise Tax Board's capital gains guidance. An additional 1% Mental Health Services tax applies to taxable income above $1,000,000, taking the top marginal rate to 13.3%.
That asymmetry matters. Federal law is generous to a post-death gain; California is not. A $45,000 gain is taxed by California at your ordinary rate, not a reduced one.
What the Step-Up Does Not Cover
- Property gifted during the decedent's lifetime. A house transferred to you before death generally carries over the decedent's basis, not a stepped-up one — which is why "just put me on the deed" is frequently expensive advice. Publication 551 also excludes a step-up on appreciated property you or your spouse gave the decedent within one year before death.
- The property tax reassessment question. This is separate from income tax entirely. California's Proposition 19 sharply narrowed the parent-child exclusion from property tax reassessment. Inheriting a home does not automatically mean inheriting its assessed value.
- Rental depreciation recapture, if the home was used as a rental after you inherited it.
- The $250,000/$500,000 home-sale exclusion, which applies to a home you lived in as your primary residence for two of the previous five years. An inherited home you never lived in does not qualify. The IRS covers the exclusion in Publication 523, Selling Your Home.
Selling Costs Reduce the Gain — Which Makes the Commission Question Sharper
Your taxable gain is net of selling expenses, including the real estate commission. That is sometimes offered as a reason not to worry about the commission. The arithmetic does not support it.
On a $890,000 sale with an $845,000 basis, a 6% commission is $53,400. It reduces your $45,000 gain to zero, which sounds efficient until you notice that you spent $53,400 to avoid tax on $45,000. You did not save money; you eliminated the gain by giving away more than the gain was worth.
LOQOL's Charlie AI flat fee at that price tier is $4,399. That leaves a taxable gain of roughly $40,600 — and roughly $49,000 more in your pocket than the 6% listing, before any tax. Paying tax on a gain is nearly always better than not having the gain.
| Listing Structure | Cost on an $890,000 Sale | Taxable Gain After Costs | You Keep vs 6% |
|---|---|---|---|
| Traditional 6% | $53,400 | $0 | — |
| Traditional 5.5% (CA average) | $48,950 | $0 | $4,450 |
| LOQOL Charlie AI (under $1M tier) | $4,399 | $40,601 | $49,001 |
| LOQOL White Glove (full service, fixed) | ~$13,200 | $31,800 | $40,200 |
California's average total commission is 5.5% per Clever's California survey. LOQOL is a licensed California brokerage, DRE #02261474; Charlie is LOQOL's AI agent and a licensed California agent is the agent of record on every listing. Professional photography is not included in either tier.
Frequently Asked Questions
Do I pay capital gains tax on a house I inherited in California?
Only on appreciation after the date of death. The step-up in basis resets your cost basis to the fair market value on the date the decedent died, so lifetime appreciation is not taxed to you.
How do I prove the date-of-death value?
With a formal appraisal as of the date of death, ordered by the executor or administrator. A retrospective appraisal is the standard evidence, and it is worth getting even when no estate tax return is required — it is what establishes your basis if the sale is ever examined.
What if the house sells for less than the date-of-death value?
You may have a capital loss. On an inherited property held as an investment rather than a personal residence, that loss can generally be used, subject to the usual capital-loss rules. Ask your CPA how it applies to your return.
Does California tax the gain differently from the IRS?
Yes. Federal law taxes it at long-term capital gains rates. California has no preferential capital gains rate and taxes it as ordinary income at 1%–12.3%, plus a 1% surcharge above $1,000,000 of taxable income.
Does the $250,000 home-sale exclusion apply to an inherited house?
Only if you lived in it as your primary residence for two of the five years before the sale. Inheriting a home you never occupied does not qualify you for the exclusion.
Do I need to finish probate before I can sell?
Usually, though California has simplified procedures for smaller estates and for property held in a living trust. We cover the thresholds and the exceptions in do I need probate to sell an inherited house in California.
Does selling faster reduce my tax?
It reduces the window in which post-death appreciation can accrue, so a sale close to the date of death usually produces a smaller gain. That is a reason to be organized, not a reason to accept a below-market cash offer.
Next Steps
If you are handling an estate sale, the two decisions that move the most money are getting a date-of-death appraisal and choosing a listing structure that does not hand a percentage of a stepped-up asset to a listing side.
