Taxes when selling a house in a California trust after death

Short answer: Selling a house held in a California living trust after death is usually still about three separate things: (1) capital gains on the sale, often starting from a step-up in basis as of the date of death; (2) the county property-tax bill, where Proposition 19 may or may not let a child keep a parent’s low assessed value; and (3) the trust’s own accounting to beneficiaries.

This page vs. the general inherited-sale tax worksheet

My general page, do I owe tax if I sell an inherited house, walks through sale price, date-of-death value, selling costs and the two situations that often change the math (name on the deed early; rental depreciation). Use that worksheet for the blanks. This page adds the trust layer: who is the seller on the closing statement, and which tax questions the trustee should take to the CPA.

Who is the seller when the house is in a trust?

On a funded living trust, the successor trustee typically signs as trustee. Escrow and the CPA need the trust’s taxpayer details and the date of death. Beneficiaries are not automatically the sellers just because they will receive proceeds. How the trust distributes cash after closing can matter for who reports what—another reason the CPA, not the listing broker, owns the return.

Step-up in basis after death

For most inherited houses, including many held in a revocable living trust that became irrevocable at death, the starting basis is the fair market value on the date of death (a step-up), not what the decedent paid years earlier. Gain, if any, is roughly: sale price, minus selling costs, minus that date-of-death value, plus improvements paid after death. If the house was only partly in the trust, or if someone was added to title before death, part of the old basis can survive. Tell the CPA how title read on the date of death.

Capital gains vs. California tax

Concepts already on the general worksheet still apply. Federal tax on a long-term capital gain is often 15% or 20%, and some filers also owe the 3.8% net investment income tax. California taxes the gain as ordinary income at the filer’s rate, with no special low capital-gains rate. Do not multiply a gain by a single percent and treat it as what you owe. Your CPA applies the rates to the actual return.

Proposition 19 is not capital gains

Proposition 19 is about property tax—whether a child can keep a parent’s low assessed value—and it depends on living in the house and filing on time with the county assessor. It is a separate bill from capital gains on the sale. Do not mix the two when deciding whether to keep or sell a trust house. See the same distinction on the inherited-sale tax page.

What the trustee should bring to the CPA

1. The trust (or certification of trust) and the death certificate.
2. How title read on the date of death, and any earlier deeds that added a child or co-owner.
3. A date-of-death value (appraisal or other support the CPA will accept).
4. Whether the house was a rental and any depreciation history.
5. The draft closing statement: price, commission, credits, payoff.

Frequently asked questions

Do you pay capital gains when selling a house in a California trust after death?

Often the starting point is a step-up in basis as of the date of death, so tax—if any—is on the gain after that, minus selling costs. A CPA applies federal and California rules to the actual return. This is not a tax bill.

Is a trust sale taxed differently from inheriting the house outright?

The big ideas (step-up, selling costs, rental depreciation, early deed additions) are similar. The trust layer adds who signs as seller and how the trust accounts to beneficiaries. Bring the trust and title history to the CPA.

Does Proposition 19 reduce capital gains on a trust house?

No. Proposition 19 is about the county property-tax assessment, not capital gains on the sale. Keep the two bills separate.

Who reports the sale when a successor trustee sells?

Usually the trustee signs as trustee, and the CPA decides how the sale appears on the returns. Beneficiaries are not automatically the sellers just because they will receive proceeds.

Can Bill Gross prepare the tax return?

No. Bill Gross is a real estate broker (DRE #01022275), not a CPA or attorney. He can help sell the house; a CPA or tax attorney handles the return.
