The San Francisco Homeowners' Exemption (and Why It Matters More Than $80)
By Danielle Cui · August 8, 2026
The homeowners' exemption is worth about $80 a year — small enough that plenty of San Francisco owners never bother. That's a mistake, and not mainly because of the $80.
The mechanics
If you own and occupy a home as your principal place of residence, you can claim an exemption of up to $7,000 off the assessed value. At San Francisco's FY 2025-26 rate of 1.18268325%, that's roughly $80 a year.
- The form is BOE-266, Claim for Homeowners' Property Tax Exemption, filed with the SF Office of the Assessor-Recorder.
- File once. It auto-renews as long as you keep occupying the property as your principal residence. You don't refile annually.
- New owners are typically mailed a claim form automatically after a purchase — but "typically" isn't "always," so verify rather than wait.
- Eligibility extends to owners, co-owners, and purchasers named in a contract of sale.
The deadline has two tiers
Timing is measured against the January 1 lien date for the year you occupied the home:
| File by | You get |
|---|---|
| February 15 (5:00 p.m.) | 100% of the exemption |
| February 16 – December 10 (5:00 p.m.) | 80% of the exemption |
So a late claim isn't worthless — it's just reduced for that year, and full going forward. If you've owned for years and never claimed it, file now rather than waiting for a February.
The real reason to have it
Here's what makes this more than a rounding error.
California Revenue & Taxation Code §167 creates a rebuttable presumption in the taxpayer's favor at an assessment appeal hearing — meaning the Assessor has to affirmatively establish that its value is correct, rather than you having to prove it wrong.
But §167(c) defines the qualifying property as a dwelling that is the owner's principal place of residence and qualifies for the homeowners' property tax exemption.
Read that again: the homeowners' exemption is the gatekeeper for the burden-of-proof shift. An owner who never filed the $80 form may walk into a hearing carrying a burden they didn't have to carry. On a $1.5M San Francisco property, an appeal is often worth $2,000–$5,000 a year, so a procedural advantage in that hearing dwarfs the exemption itself. (What the burden shift means in practice.)
If you're planning to appeal your assessment, confirm the exemption is on your record first.
How to check whether you already have it
Look at your tax bill or Notice of Assessed Value for a homeowners' exemption line showing a $7,000 reduction. If it's absent and this is your principal residence, you're leaving money and leverage on the table. (How to pull your assessment record.)
Two situations where it commonly goes missing:
- You bought and never received (or never returned) the claim form.
- The property is held in a trust or an LLC, or title changed in a way that reset things. Trust ownership generally doesn't disqualify a principal residence, but the claim may need to be refiled after a title change.
Keep it honest
The exemption applies to one principal residence. Claiming it on a rental, a second home, or two properties at once invites an escape assessment plus penalties later — and forfeiting the §167 presumption is the least of what goes wrong. If you move, notify the Assessor.
Same logic in reverse: if the property genuinely stopped being your principal residence, you also lose the §167 advantage for appeals on it, which is worth knowing before you plan a hearing strategy around it.
Other exemptions worth checking
San Francisco and the state administer several others with real dollar value — the disabled veterans' exemption, exemptions for nonprofit and religious use, and various Prop 19 base-year-value transfers for owners over 55, severely disabled owners, and wildfire or disaster victims. These are separate from the homeowners' exemption and have their own forms and deadlines; the Assessor-Recorder's office is the place to start.
The sequence if you're appealing this year
- Confirm (or file for) the homeowners' exemption — it's the §167 qualifier.
- Pull your assessment record and audit the property characteristics for errors. (How.)
- Compare your assessed value against real comparable sales near the January 1 lien date. CompFinder does this step for San Francisco properties.
- File by September 15 if there's a gap. (The process.)
Frequently asked questions
How much is the San Francisco homeowners' exemption worth?
It removes up to $7,000 from your assessed value, which at the FY 2025-26 rate of 1.18268325% saves roughly $80 a year. Its larger value is qualifying you for the §167 burden-of-proof presumption at an assessment appeal hearing.
What is the deadline to file for the homeowners' exemption?
File by 5:00 p.m. on February 15 for the full exemption. A claim filed between February 16 and 5:00 p.m. on December 10 gets 80% of the exemption for that year, with the full amount applying in later years.
Do I have to refile the homeowners' exemption every year?
No. It auto-renews as long as you continue to own and occupy the property as your principal place of residence. You should notify the Assessor if that changes.
Why does the homeowners' exemption matter for a property tax appeal?
Because Revenue & Taxation Code §167 shifts the burden of proof onto the assessor only for a dwelling that is the owner's principal residence and qualifies for the homeowners' exemption. Without the exemption on your record, you may carry a burden at your hearing that you didn't need to.
How do I know if I already have the homeowners' exemption?
Check your property tax bill or Notice of Assessed Value for a homeowners' exemption line reducing your assessed value by $7,000. It commonly goes missing when a claim form was never returned after a purchase, or after a title change into a trust or entity.
