Trusts and estates
When property passes between generations in California, two systems apply at once: income tax basis and county reassessment. They follow different rules and the second one surprises people.
Step-up in basis
Assets included in an estate generally take a new income tax basis equal to fair market value at the date of death. For real property held for decades in Southern California, that adjustment is often the single largest item in the plan, because it can eliminate the gain that would otherwise be taxed on a later sale.
How title is held determines how much of the property receives the adjustment, which is why the form of ownership matters long before anyone is administering an estate.
Reassessment on inherited property
California has narrowed the parent-to-child exclusion from property tax reassessment. The exclusion now applies only where the property was the parent’s principal residence and the child makes it their own principal residence, and it is capped — value above the cap is added to the reassessed base.
The practical result is that an inherited rental or second home in Riverside or San Bernardino County is generally reassessed at current market value. Families who assumed the old Proposition 13 base would carry forward often discover otherwise, and the filing deadlines that follow a transfer are short.
Trust income tax returns
A trust that holds income-producing property files its own return. California fiduciary returns are filed on Form 541, alongside the federal return, and trust tax brackets compress quickly — the top rate arrives at a far lower income level than it does for an individual.
That compression is why distribution timing matters. Income distributed to beneficiaries is generally taxed to them rather than to the trust, and the decision is made against each beneficiary’s own bracket.
Common questions
- Does inherited property in California get reassessed?
- Usually, yes. Under current California law, the parent-to-child exclusion from reassessment applies only when the property was the parent’s principal residence and the child uses it as their own principal residence, and the exclusion is capped in value. Inherited rentals, vacation homes, and commercial property are generally reassessed at market value.
- What is step-up in basis on California real estate?
- Property included in a decedent’s estate generally receives a new income tax basis equal to its fair market value at the date of death. If it is sold shortly afterwards, there may be little or no taxable gain. Step-up affects income tax only — it does not prevent property tax reassessment, which is a separate county determination.
- Does a trust holding rental property have to file a tax return?
- Generally yes, once it has income above the filing threshold. California fiduciary income tax returns are filed on Form 541. Whether the tax is paid by the trust or by the beneficiaries depends on what is distributed during the year.
