California property tax exemptions can lower what you owe on your home, or in some cases eliminate the bill entirely. The four that matter for most people are the homeowners’ exemption, the disabled veterans’ exemption, the welfare exemption for nonprofits, and the base-year value transfers created by Proposition 19. Each has its own eligibility rules, filing forms, and deadlines, and the savings range from about $70 a year at the low end to a full wipeout of the tax bill at the high end.
Homeowners’ Exemption
If you own and live in your home as your primary residence, you qualify for a $7,000 reduction in assessed value. At California’s roughly 1% base tax rate, that saves about $70 a year.1California State Board of Equalization. Homeowners’ Exemption Modest, but claiming it is simple.
You must occupy the home as your principal residence on January 1 (the lien date) of the tax year. Rentals, vacation homes, second residences, and vacant or under-construction properties do not qualify.2BOE.ca.gov. Property Tax Savings: Homeowners’ Exemption
File form BOE-266 with the county assessor where the property sits. This is a one-time filing, not annual. Once the exemption is granted it stays in place until you sell, move out, rent the home, or convert it to another use, at which point you’re required to notify the assessor in writing.2BOE.ca.gov. Property Tax Savings: Homeowners’ Exemption To receive the full exemption for the fiscal year starting July 1, file by February 15. File between February 16 and December 10 and you get 80% of the exemption, a $5,600 reduction.3Orange County Assessor Department. Homeowners’ Exemptions After December 10, nothing for that year.
Disabled Veterans’ Exemption
The disabled veterans’ exemption is worth far more than the homeowners’ version. For the 2026 assessment year it reduces assessed value by either $180,671 or $271,009, depending on household income.4BOE.ca.gov. LTA 2025/014 – Disabled Veterans’ Exemption Increases for 2026 For many veterans, that eliminates the property tax bill entirely. The amounts adjust annually for inflation under Revenue and Taxation Code Section 205.5.
The basic exemption of $180,671 is available to all qualifying veterans regardless of income. The low-income exemption of $271,009 is available when total household income is $81,131 or less.4BOE.ca.gov. LTA 2025/014 – Disabled Veterans’ Exemption Increases for 2026
To qualify, the veteran must be rated 100% disabled or 100% unemployable due to a service-connected injury or disease and must have received a discharge under conditions other than dishonorable. The home must be the veteran’s principal residence as of January 1 of the tax year. Unmarried surviving spouses of qualifying veterans are also eligible, even if the veteran never claimed the exemption during their lifetime, as long as the veteran would have qualified or died from a service-connected cause.5BOE.ca.gov. Disabled Veterans’ Exemption
You cannot claim both the homeowners’ exemption and the disabled veterans’ exemption on the same property. Since the veterans’ version is worth far more, any veteran who qualifies should claim that one.
Welfare Exemption for Nonprofits
The welfare exemption can eliminate property taxes entirely for qualifying nonprofits. It applies to property used exclusively for charitable, religious, hospital, or scientific purposes.6Board of Equalization. Property Tax Welfare Exemption The trade-off is more paperwork and ongoing compliance than any other California property tax exemption.
An organization must be nonprofit, with no part of its earnings benefiting any private individual, officer, or shareholder. The property must be used exclusively for the qualifying purpose. Mere ownership by a nonprofit is not enough. The organization must hold a current tax-exempt letter from the IRS or the California Franchise Tax Board, and its formation documents must permanently dedicate its property to the exempt purpose, with assets going to a similarly purposed entity if the organization dissolves.7California Legislative Information. California Revenue and Taxation Code 214
The application has two parts. First, the organization files form BOE-277 to obtain an Organizational Clearance Certificate from the Board of Equalization, confirming it meets the structural and operational requirements.8California State Board of Equalization. Claim Forms for Organizational Clearance Certificate – Welfare Exemption Second, the organization files form BOE-267 with the county assessor for each property it wants exempted. Unlike the homeowners’ exemption, the welfare exemption must be claimed by February 15 every year.6Board of Equalization. Property Tax Welfare Exemption
Proposition 19 Base-Value Transfers
Proposition 19, which took effect in stages starting in 2021, created two ways to carry a property’s low tax base to a different property. These aren’t exemptions in the traditional sense, but they prevent a reassessment that would otherwise spike your bill when you move or inherit a family home.
Parent-to-Child and Grandparent-to-Grandchild Transfers
Under Revenue and Taxation Code Section 63.2, a parent can transfer a family home to a child without triggering a full reassessment, but only if specific conditions are met.9California State Board of Equalization. Proposition 19
The home must have been the parent’s principal residence, and the child must move in and use it as their own principal residence within one year of the transfer. The child must also file for the homeowners’ or disabled veterans’ exemption on the property within that same window. If the child ever stops using the home as their primary residence, the property gets reassessed at current market value.9California State Board of Equalization. Proposition 19
There’s also a value cap. If the property’s market value at transfer exceeds the existing assessed value by more than an inflation-adjusted threshold, the excess gets added to the tax base. For transfers between February 16, 2025, and February 15, 2027, that threshold is the property’s factored base year value plus $1,044,586.10BOE.ca.gov. Proposition 19
The exclusion applies to family farms as well as family homes. Grandparent-to-grandchild transfers qualify only if the grandchild’s parent (the grandparent’s child) is deceased. Transfers between siblings do not qualify.11BOE.ca.gov. Taxpayers’ Rights Advocate Information Sheet – Property Tax Savings: Transfers Between Parents and Children To claim it, file form BOE-19-P with the county assessor within three years of the transfer or before the property is sold to a third party, whichever comes first.9California State Board of Equalization. Proposition 19
Base-Year Value Transfers for Homeowners 55 and Older
If you’re 55 or older and sell your primary residence, Proposition 19 lets you transfer your current property tax base to a replacement home anywhere in California. You can do this up to three times in your lifetime. Before Proposition 19, this benefit was limited to certain counties and could only be used once.12Homeowners – Proposition 19. Proposition 19 – LA County Assessor
You must be 55 or older at the time you sell the original property. The replacement home must be purchased or newly built within two years of the sale. Both homes must qualify as your primary residence and both must be eligible for the homeowners’ or disabled veterans’ exemption. Both transactions must involve real consideration such as cash, debt, or exchange of property. Gifts don’t qualify.
You can buy a more expensive replacement home, but only the value up to the original’s market value carries the old tax base. Any excess is taxed at current value. The thresholds depend on timing: 100% of the original’s market value if you buy before selling, 105% within the first year after selling, and 110% within the second year.13sjgov.org. Base Year Age 55 and Older
The same rules and three-use lifetime cap apply to severely disabled homeowners of any age.
Filing Deadlines and What Happens if You File Late
February 15 matters differently depending on the exemption. For the homeowners’ exemption, claims filed between February 16 and December 10 receive 80% of the benefit, or a $5,600 reduction instead of $7,000.3Orange County Assessor Department. Homeowners’ Exemptions After December 10, the exemption is gone for that fiscal year, though you can file for the next one.
For the welfare exemption, the stakes are higher. Nonprofits must file annually by February 15 for the full 100%.6Board of Equalization. Property Tax Welfare Exemption A missed deadline can produce a tax bill of tens of thousands of dollars on a single property.
For Proposition 19 parent-to-child transfers, filing after the one-year window doesn’t forfeit the exclusion outright, but it applies only from the year of filing forward. You lose the retroactive benefit back to the transfer date.9California State Board of Equalization. Proposition 19
Penalties for Improperly Claimed Exemptions
Claiming an exemption you don’t qualify for, whether intentionally or by neglect, triggers what California calls an escape assessment. The county assessor adds the exempted value back to the tax roll and bills you for the taxes you should have paid, plus interest under Revenue and Taxation Code Section 506.14Justia Law. California Revenue and Taxation Code 531-538
How far back the assessor can reach depends on the nature of the improper claim. For standard escape assessments, the statute of limitations is four years from July 1 of the assessment year in which the property escaped taxation. If the improper claim involved knowingly false or incomplete information, the penalty under Section 504 applies and the lookback period extends to eight years.14Justia Law. California Revenue and Taxation Code 531-538
The homeowners’ exemption has its own provision under Section 531.6. If the exemption was allowed because the assessor made an error, interest is forgiven. If you submitted incorrect information knowing it was wrong, or you failed to notify the assessor when you moved out or started renting the property, both the Section 504 penalty and interest apply.15Justia Law. California Revenue and Taxation Code 531-538 If your eligibility changes, notify the assessor promptly. A few minutes of paperwork now is far cheaper than years of back taxes and penalties later.
