How to Lower Your Property Tax in California
You can't escape Proposition 13, but there are several legitimate, free ways to reduce a California property-tax bill — claiming exemptions you're owed, appealing an over-stated assessment, and using Proposition 8 and Proposition 19. Here are the ones that actually work, in order of easiest payoff.
1. Claim the Homeowners' Exemption (and any you qualify for)
If you own and live in the home, the Homeowners' Exemption takes $7,000 off your assessed value — free, filed once. Veterans, seniors, and nonprofits have larger programs; see all California property-tax exemptions. Start here — it's the easiest win.
2. Appeal your assessed value
If the assessor's value is higher than what your home is worth, you can file an assessment appeal with your county board. See how to challenge your property-tax assessment — the window is generally July 2 to September 15 or November 30, depending on the county.
3. Request a Proposition 8 decline-in-value review
When market value falls below your Proposition 13 value, a Proposition 8 review can temporarily lower your assessed value toward the lower market — reducing your bill until values recover. Many assessors do this automatically, but you can request it.
4. Transfer your low base year with Proposition 19 (55+ or disabled)
Homeowners 55 or older (or severely disabled) can carry their low Proposition 13 base-year value to a new California home instead of being reassessed at the new price. Estimate it with the Prop 19 calculator.
5. Check your bill for errors and missing exemptions
Read your tax bill: confirm the Homeowners' Exemption line is applied, check the assessed value against what you paid, and watch for Mello-Roos or direct assessments that don't belong to your parcel. Errors are more common than people expect.
6. Make sure new construction was assessed correctly
Only the new construction is reassessed, not the whole home — see what triggers a reassessment. If a remodel or ADU was over-assessed, that's grounds for an appeal.
7. Know what won't work
California has no general way to freeze or cap your bill below Proposition 13, and “services” promising to slash your taxes for a fee rarely beat a free, correct exemption and appeal. Stick to the legitimate routes above.
Start with the free wins
Most owners leave money on the table by not claiming the Homeowners' Exemption or not checking their bill. Do those first — they cost nothing and take minutes — before considering a paid service.
Frequently Asked Questions
How can I lower my property tax in California?
Claim the $7,000 Homeowners' Exemption (and any veteran/senior exemption you qualify for), appeal your assessed value if it's too high, request a Proposition 8 decline-in-value review when the market drops, transfer your low base year under Proposition 19 if you're 55+ or disabled, and check your bill for errors or misapplied assessments. These are the legitimate, no-cost ways.
Can you reduce property taxes in California after buying?
A purchase resets your assessed value to the price you paid (that's a reassessment), so you can't undo that. But you can still claim the Homeowners' Exemption, make sure no extra assessments were added in error, and — if the market later falls below your purchase price — request a Proposition 8 reduction. Seniors moving can use Proposition 19 to avoid the reset entirely.
Does appealing your property tax assessment work?
It can, if your assessed value is genuinely above market value — for example after a downturn or if the assessor overstated your home. You file an appeal with the county assessment appeals board during the filing window and bring comparable sales. If you're right, the reduction lowers your bill; it costs nothing to file yourself.
Is there a senior property tax freeze in California?
Not a freeze, but Proposition 19 lets homeowners 55 or older transfer their existing (low) Proposition 13 base-year value to a replacement home anywhere in California, and the Property Tax Postponement program lets qualifying seniors defer payment. Both effectively keep a senior's bill from jumping.
