Property Tax Exemptions You're Probably Not Claiming in California

California's homeowner exemption is one of the smallest in the country: $7,000 off your assessed value, worth maybe $70 to $90 a year. If that's all you knew about California property tax, you'd be missing the part that actually matters. The real savings sit in a cap on how fast your assessed value can rise, and a rule that lets you carry that low value with you when you move.

The exemption itself, honestly small

Every owner-occupied primary residence in California qualifies for the Homeowners' Exemption: $7,000 off your assessed value, set in the state Constitution. File Form BOE-266 once with your county assessor, and it continues automatically. It's worth filing. It's also not going to change your life.

The part that actually matters

Under Proposition 13, your home's assessed value can only rise by 2% a year, or less, no matter how much the market moves, and it only resets when the property changes hands. Owners who've held a home for a decade or two can end up with an assessed value a fraction of what the home would sell for today. This is automatic. You don't file for it. It's just how Prop 13 works.

The rule that surprises long-time owners the most

Here's the one that gets missed: if you're 55 or older, severely and permanently disabled, or a victim of a wildfire or governor-declared disaster, Proposition 19 lets you transfer that low assessed value to a new home anywhere in California, up to three times. A lot of longtime owners assume moving means starting over at market-rate assessment. It doesn't have to. You have to file for it (Form BOE-19-B for the age-based track, BOE-19-D or BOE-19-V for disability or disaster), and both the old and new home have to qualify for the homeowners' or disabled veterans' exemption, but the transfer itself can be worth far more than the sale price difference between the two homes.

The exemption for disabled veterans, and the trade-off nobody explains

California also runs a Disabled Veterans' Exemption, separate from the $7,000 homeowners' exemption and worth considerably more: $180,671 of assessed value for 2026, or $271,009 if household income falls under the program's income limit. Here's the trade-off: you can't have both. The disabled veterans' exemption replaces the $7,000 homeowners' exemption rather than stacking on top of it. For almost any qualifying veteran, that's an easy trade, but it's worth knowing it's a swap, not an addition.

The name that means two different things

One more thing worth flagging before you search for more on this: "homestead exemption" in California can refer to two completely unrelated laws. Everything above is the property tax exemption. There's a separate homestead exemption under the Code of Civil Procedure that protects home equity from creditors in a lawsuit, worth several hundred thousand dollars depending on your county, and it has nothing to do with your tax bill. If an article or a search result starts talking about six-figure homestead protection, it's almost certainly talking about the creditor-protection law, not the tax exemption.

A bill to raise the small senior exemption from $7,000 to $50,000, SB 566, was introduced in 2025. It failed in committee in February 2026 on a tied vote and hasn't advanced since. Worth knowing it exists. Not worth planning around.

What to actually check

Confirm your Homeowners' Exemption is on file with your county assessor. If you're 55 or older and thinking about moving within California, look into Prop 19 portability before you assume you'll lose your current assessed value. And if you're a disabled veteran, confirm you're claiming the disabled veterans' exemption instead of the smaller homeowners' exemption, not both.
