Legal Information Notice
This guide provides general educational information about capital gains tax on inherited property in California. It is not tax or legal advice. Tax rules are complex, change frequently, and vary by individual circumstances. Consult a licensed tax attorney or CPA for guidance on your specific situation. Reading this does not create an attorney-client relationship.
The Core Rule: Inheriting Property Is Not a Taxable Event
One of the most common misconceptions about inheriting property is that it triggers an immediate tax bill. It does not. The act of inheriting property is not itself a taxable event under federal or California law.
Capital gains tax applies when you sell property — and even then, only on the gain realized above your tax basis. The critical question for heirs of California real estate is: what is your basis in the inherited property?
The Stepped-Up Basis: Your Starting Point
When you inherit property, your federal income tax basis is typically "stepped up" to the fair market value of the property on the date of the decedent's death. This is governed by IRC Section 1014 and is one of the most valuable provisions in the tax code for heirs of appreciated property.
The practical effect: all of the capital gains that accumulated during the original owner's lifetime are permanently wiped out for income tax purposes. You start fresh at current market value.
A Classic California Illustration
A parent purchased a San Jose home in 1992 for $250,000 (original basis). At death in 2025, the home is worth $1,800,000. The parent's embedded gain was $1,550,000.
The heir's stepped-up basis = $1,800,000. If the heir sells immediately for $1,800,000, the capital gain is $0 — the entire $1,550,000 accumulated gain is eliminated.
If the heir holds the property for 3 years and sells for $2,100,000, they owe capital gains tax only on the $300,000 gain that occurred after inheritance — not the original $1,550,000.
Illustrative only. Actual tax calculations depend on individual circumstances. Consult a CPA for your specific sale calculations.
Federal Capital Gains Tax Rates for Inherited Property
For federal purposes, inherited property is automatically treated as long-term capital gains property — regardless of how long you actually hold it. This means even if you sell the property one week after inheriting, you pay long-term rates (not the higher short-term ordinary income rates).
| Filing Status / Income | Federal Long-Term Capital Gains Rate |
|---|---|
| Single — up to $47,025 (2024) | 0% |
| Single — $47,026 to $518,900 | 15% |
| Single — over $518,900 | 20% |
| Married Filing Jointly — up to $94,050 | 0% |
| Married Filing Jointly — $94,051 to $583,750 | 15% |
| Married Filing Jointly — over $583,750 | 20% |
| High-income taxpayers (may apply) | +3.8% Net Investment Income Tax |
Note: Income thresholds are adjusted annually. Consult a tax professional for current year rates.
California State Capital Gains Tax: The Important Difference
California does not follow the federal preferential long-term capital gains rates. California taxes all capital gains — including long-term gains — as ordinary income at state tax rates. California's top marginal rate is 13.3%, which applies to taxable income over $1 million.
This means a California heir selling an inherited property with a $500,000 gain above their stepped-up basis faces:
- Federal capital gains tax: up to 20% (plus potential 3.8% NIIT)
- California state income tax: up to 13.3%
- Combined marginal rate on the gain: potentially 37.1% or higher
For large gains on appreciated California real estate, state tax can represent a significant portion of the total tax burden — one reason many California heirs consider strategies such as installment sales, 1031 exchanges on investment property, or holding the property rather than selling immediately.
Key Scenarios: When Heirs Do and Don't Owe Capital Gains
Scenario 1: Sell Quickly at or Near Stepped-Up Value
Heir inherits a home with a $1,200,000 stepped-up basis. Sells 60 days later for $1,215,000. Federal gain = $15,000. California gain = $15,000. Tax is minimal — and selling costs may largely offset the small gain.
Scenario 2: Hold the Property and Sell Later
Heir inherits at $1,200,000 stepped-up basis. Holds 5 years. Sells for $1,750,000. Gain = $550,000. Both federal and California taxes apply on the $550,000. The longer the holding period, the more gain can accumulate above the stepped-up basis.
Scenario 3: Convert Inherited Home to Primary Residence
An heir who moves into the inherited home as their primary residence may be able to use the Section 121 primary residence exclusion — up to $250,000 of gain ($500,000 for married couples filing jointly) — if they satisfy the ownership and use tests (generally, lived in the home as their primary residence for at least 2 of the last 5 years before sale). The exclusion applies on top of the stepped-up basis. This can significantly reduce or eliminate federal tax on a later sale. Note that California conforms to this exclusion.
Scenario 4: Investment Property — Consider a 1031 Exchange
For inherited investment or rental property, a 1031 like-kind exchange may allow an heir to defer capital gains tax by reinvesting sale proceeds into a new investment property. The heir must follow strict IRS rules and timelines. Consult a qualified intermediary and tax advisor before attempting a 1031 exchange on inherited property.
The Prop 19 Interaction
Remember that capital gains tax and property tax are two separate issues. A property that avoids capital gains tax (because it is sold at the stepped-up basis) may still face a large property tax reassessment under Prop 19. And a property that avoids Prop 19 reassessment (because the heir moves in) may still generate capital gains if held and sold years later above the stepped-up value.
These are separate systems that must be considered together when planning for inherited California real estate. See our Prop 19 guide and stepped-up basis guide for more detail.
