Prop 19 property tax estimator

Two quite different things share one name. One half lets some homeowners carry a low tax base to a new home. The other decides what an inherited home is reassessed at. This estimates both - and for a move, buying before selling and selling before buying give genuinely different answers.

This estimator needs JavaScript, which is not running right now. In short: a base year value transfer lets qualifying owners carry their existing assessed value to a replacement home, with anything paid above a benchmark added on top. For an inherited family home, the exclusion covers the parent's assessed value plus a fixed statutory amount, and value above that is added to the new base.

The full guide explains both halves, or call 619-987-6543 and we will talk it through. Families who do well are the ones who asked before the transfer rather than after.

Which situation?

I am moving and want to carry my tax base I am inheriting a home from a parent

Your move

Current assessed value of your home

From your property tax bill - the assessed or factored base year value. This is not what the home is worth.

What your home sells for

Price of the replacement home

Order of buying and selling

This is the input people do not realise they control. It sets the benchmark your replacement price is measured against, and the replacement must be bought or built within two years of the sale.

Optional

Your property tax rate (%)

Add this to see the result as annual dollars. We do not assume a rate: Prop 13's 1% is a floor, and voter-approved local bonds on top of it vary by tax rate area.

Estimated result

An estimate of assessed value only. It does not determine eligibility, and it is not a filing. Your county assessor decides both, there are deadlines that cost real money to miss, and this is not tax advice.

The figure this uses, and when it changes

The intergenerational exclusion is the property's factored base year value plus $1,044,586. That amount applies from 16 February 2025 to 15 February 2027 and adjusts again on 16 February 2027. Take the figure current on your own transfer date from the California State Board of Equalization - not from any website, including this one.

Two things this tool will not do. It will not tell you whether you qualify - that turns on age, disability status, occupancy and timing, and the assessor decides it. And it will not calculate any tax you owe on a sale; that is a different question with a different professional.

Proposition 19 covers both halves properly, including the deadlines - the three-year filing window for a base transfer, and the one-year occupancy requirement for an inherited home.

General information, not legal, tax or financial advice. Tax rules change and every family's situation differs - verify the current position with your county assessor and your own adviser.

Weighing a move, or an inheritance?

Send this over and we will talk it through. The families who do well are the ones who asked before the transfer rather than after - once a deed is recorded there is far less room to plan.
