How the California homeowners’ exemption works
The homeowners’ exemption comes from the California Constitution (Article XIII, section 3(k)) and Revenue and Taxation Code section 218. It reduces the assessed value of an owner-occupied home by $7,000. Assessed value is the value the county uses to calculate your property tax.
It is a $7,000 reduction in value, not a $7,000 refund. At the 1% base tax rate, that works out to about $70 a year in lower taxes.
Who qualifies
- You own the home and it’s your principal place of residence on the January 1 lien date.
- You can only have one principal residence, so you can only claim one homeowners’ exemption.
- Rentals, vacation homes and second homes don’t qualify.
- A property receiving a larger exemption, such as the disabled veterans’ exemption, doesn’t get this one as well.
How and when to file
You file Form BOE-266, Claim for Homeowners’ Property Tax Exemption, with the county assessor. In LA County, that’s the Office of the Assessor. LA County says the assessor typically mails a claim form a few months after your deed is recorded, but you don’t have to wait for it.
- By February 15: full exemption for that year.
- February 16 through December 10: 80% of the exemption.
- After December 10: nothing for that year.
New owners may also get the exemption on a supplemental assessment. Per the BOE-266 form, the full amount is available if you file within 30 days of the Notice of Supplemental Assessment, and 80% if you file later but before the supplemental bill’s first installment goes delinquent.
Once granted, the exemption stays in place. If you move out or rent the home, you’re responsible for telling the assessor.
03 Real-world example
What the homeowners’ exemption saves
The savings depend on your total tax rate. Here’s the math at the 1% base rate and at an illustrative total rate.
| Scenario | Exemption | Tax rate | Yearly savings |
|---|---|---|---|
| Filed by February 15 | $7,000 | 1% base | $70 |
| Filed by February 15 | $7,000 | 1.2% illustrative | $84 |
| Filed late (80%) | $5,600 | 1.2% illustrative | $67.20 |
| Over 10 years, filed on time | $7,000 | 1.2% illustrative | $840 |
Assumptions: 1.2% is an illustrative total rate (1% base plus voter-approved debt). Actual rates vary by tax rate area. Direct assessments are flat charges and aren’t reduced by the exemption.
04 What most people overlook
Why buyers miss the homeowners’ exemption
- The seller had it, so they assume it carries over. It doesn’t. A new owner has to file their own claim, even if the home already showed the exemption.
- The form looks like junk mail. It arrives months after closing, when you’re no longer watching for paperwork.
- Timing against the supplemental. The 30-day window after a Notice of Supplemental Assessment is short. Filing as soon as you move in avoids missing it.
- Moving out later. If you turn the home into a rental, tell the assessor. Keeping an exemption you no longer qualify for can lead to a bill for back taxes, and penalties may apply.
Small amount, no cost, one form. File it once and it keeps working every year you live there.
05 How I’d approach it
How I’d handle the homeowners’ exemption
It’s about $70 a year, but it takes ten minutes, and I’d rather you never leave money on the table.
I remind clients about the exemption at closing and again when they move in. If the closing is in January or early February, the February 15 deadline is close, so I flag it right away.
- Once your deed records, get Form BOE-266 from the LA County Assessor instead of waiting for it in the mail.
- File it as soon as the home is your principal residence.
- Keep a copy, and check your next tax bill to confirm the exemption shows up.
While you’re at it, I’ll walk you through your full ownership costs, including any supplemental tax bill and your escrow payment at your new assessed value.
