Property Tax Relief for Seniors in California: Key Programs

Property tax relief for seniors in California runs through three main programs: the Proposition 19 base year value transfer, which lets homeowners 55 and older carry their existing tax base to a new home anywhere in the state; the Property Tax Postponement program, which allows qualifying homeowners 62 and older to defer their entire tax bill; and local parcel tax waivers that eliminate flat-rate school and district assessments for residents 65 and older. Each program has its own age threshold, forms, and filing window, and a missed deadline usually means losing a full year of savings.

Moving Without Losing Your Low Tax Base

If you have owned your home for many years, your assessed value is probably far below what the house would sell for today. Revenue and Taxation Code Section 69.6, enacted through Proposition 19, lets you carry that low taxable value to a replacement home anywhere in California once you turn 55.¹ The current rules took effect in April 2021 and allow up to three lifetime transfers, with no county restriction.²

Who Qualifies

You must be 55 or older on the date you sell your original home. That home must be your principal residence and eligible for either the homeowners’ exemption or the disabled veterans’ exemption when you sell it, or become eligible within two years of buying the replacement. You then have two years from the sale date to purchase or build a new primary residence in California.¹

How Your New Assessed Value Is Calculated

If the replacement home costs the same as or less than what you sold the original for, your existing tax base transfers with no adjustment. If the replacement costs more, the difference between the two prices gets added to your old base.

Say you sell a home assessed at $200,000 for $800,000 and buy a new one for $900,000. The $100,000 gap between the sale price and the purchase price is added to your old base, giving you a new assessed value near $300,000 rather than a full reassessment at $900,000.² At the 1 percent base rate alone, that difference translates to about $6,000 per year in tax savings.

Filing the Claim

You file Form BOE-19-B with the County Assessor’s office where your replacement home is located.³ The form asks for the sale date, purchase date, and market values of both properties. Names on the application need to match the names on the grant deeds exactly. Mismatches are one of the most common reasons claims stall.

Deferring Your Entire Tax Bill Through Postponement

The Property Tax Postponement program, run by the California State Controller’s Office, lets qualifying homeowners 62 or older put off paying their property taxes on a primary residence. The state pays your bill directly to the county and records a lien on your home to secure repayment.⁴

Eligibility

Along with the age requirement, you need at least 40 percent equity in the property and annual household income of $55,181 or less under the 2025–26 program.⁵ The income limit adjusts each year. You cannot have a reverse mortgage on the property. Any defaulted taxes count against your equity when the Controller does the calculation, so back taxes can push you below the 40 percent line.⁴

Interest and When the Balance Comes Due

Deferred taxes accrue simple interest at 5 percent per year, calculated monthly. The full balance becomes payable when you sell the home, move out, pass away, or take out a reverse mortgage. Letting later property taxes or other senior liens go delinquent also triggers immediate repayment.⁴ For a homeowner on a fixed income who plans to stay in place long term, postponement effectively turns an annual expense into a debt paid out of sale proceeds or the estate. Whether the 5 percent rate is worth it depends on how it compares against what you would earn on the same cash if you did not defer.

When to Apply

The Controller’s Office opens applications on October 1 each year. For the 2025–26 program, the filing window closes on February 10, 2026.⁵ Applications go directly to the State Controller’s Office in Sacramento, not to your county assessor. Funding is limited, so filing early in the window matters. Have your income documentation ready, including Social Security statements and federal tax returns, along with Social Security numbers for every owner on the title.

Local Parcel Tax Waivers at 65

Many school districts, park districts, and other special districts levy flat-rate parcel taxes approved by local voters. Under Government Code Section 50079, those ballot measures can include an exemption for property owners 65 and older, and most do. Where they apply, the exemption removes the parcel tax entirely. In areas with multiple overlapping districts, combined savings can reach several hundred dollars a year.

Eligibility usually requires only proof of age, ownership, and occupancy as your principal residence. You apply directly to the district that levies the tax, not to the county assessor. Because each district writes its own rules into the ballot measure, availability and scope vary between jurisdictions. Start with your local school district, since school parcel taxes are typically the largest.

Keeping the Low Tax Base in the Family

If you are planning ahead for heirs rather than a move of your own, know that Proposition 19 tightened the rules for passing a home to a child. When a parent transfers a primary residence to a child, the child keeps the parent’s tax base only if the parent used the home as a primary residence and the child moves in and files for the homeowners’ or disabled veterans’ exemption within one year of the transfer. Even then, the exclusion is capped.

The child’s protected base equals the parent’s taxable value at the time of transfer plus an inflation-adjusted amount that sits at $1,044,586 for transfers between February 16, 2025, and February 15, 2027.⁶ If fair market value exceeds that combined figure, the excess is added to the taxable value.⁷

Family farms get the same value cap, applied per legal parcel, but the child does not have to live on the farm. The property must be used for cultivation, pasture, grazing, or producing an agricultural commodity as defined under Government Code Section 51201.⁷

Heirs file Form BOE-19-P for parent-to-child transfers, or Form BOE-19-G for grandparent-to-grandchild transfers (which qualify only when the grandchild’s parents are deceased). Forms go to the County Assessor where the property sits, and must be filed within three years of the transfer and before the property is transferred again to a third party.⁷ Waiting too long is the single most common way families lose this benefit.

Disabled Veterans’ Exemption

A separate program under Revenue and Taxation Code Section 205.5 gives a substantial exemption to veterans who are blind, have lost the use of two or more limbs, or are totally disabled due to a service-connected injury or disease. It applies to the veteran’s principal residence and has no age limit, but a large share of qualifying veterans are seniors, and the savings are much larger than the standard homeowners’ exemption.⁸

The exemption comes in two tiers. The basic exemption removes assessed value starting from a $100,000 base that adjusts annually for inflation. A higher low-income exemption starts from a $150,000 base, also inflation-adjusted, and is available when household income falls below a separate inflation-adjusted threshold (originally $40,000). Both the exemption amounts and the income limit compound each year using the California Consumer Price Index, so current figures are considerably higher than those statutory bases.⁹ Your County Assessor can give you the current-year amounts.

Deadlines and Filing Checklist

Missing a deadline can cost you a year of relief or trigger penalties that eat into the savings you were trying to protect. The main dates and filings:

Prop 19 base year value transfer (Form BOE-19-B): file with the County Assessor where the replacement home is located. Purchase or build the replacement within two years of selling the original.¹
Prop 19 parent-to-child exclusion (Form BOE-19-P or BOE-19-G): file with the County Assessor within three years of the transfer and before conveying the property to anyone else. The heir must move in and claim the homeowners’ exemption within one year.⁷
Property Tax Postponement: file with the State Controller’s Office during the annual window, which for 2025–26 runs from October 1, 2025, through February 10, 2026.⁵
Homeowners’ exemption: a one-time filing with the County Assessor that stays in effect while you own and occupy the home. The savings are modest (about $70 a year on a $7,000 reduction in assessed value under Revenue and Taxation Code Section 218), but the exemption is a prerequisite for several larger programs.¹⁰
Local parcel tax exemptions: apply directly with each levying district, usually the school district. Some require annual renewal, others are permanent once approved.

For any application, bring proof of age (California driver’s license, state ID, or birth certificate) and make sure the names on the application match the names on the grant deed. PTP applications also require income documentation such as Social Security statements and federal tax returns.

Filing for postponement or an exemption does not pause your regular property tax due dates. The first installment becomes delinquent after December 10 and the second after April 10, and California adds a 10 percent penalty on any delinquent installment.¹¹ If your application is still pending when a bill comes due, pay it on time and claim a refund once the relief is approved.
