Property tax relief for seniors in California comes in several forms, and most homeowners over 55 qualify for more than one. Proposition 19 lets you carry your current low assessed value to a new home anywhere in the state. The Property Tax Postponement Program pays your annual bill for you if you are 62 or older and meet the income and equity limits. On top of those, the Homeowners’ Exemption, the Disabled Veterans’ Exemption, and specific reassessment exclusions for accessibility and seismic work can each shave more off what you owe. Which ones matter depends on whether you plan to stay, move, or pass the home to family.
Moving Without Losing Your Tax Base
If you are 55 or older, Proposition 19 lets you take your current assessed value with you when you sell your home and buy another one in California. The same benefit applies to homeowners who are severely and permanently disabled and to victims of wildfire or natural disaster.1California State Board of Equalization. Proposition 19 Without this transfer, buying a new home means being reassessed at today’s market price, which for a long-term Prop 13 homeowner often multiplies the tax bill several times over.
At least one owner of the original property has to be 55 or older when it sells. You must buy or newly construct the replacement home within two years of selling the original, and it has to be your primary residence. The benefit can be used up to three times in your lifetime.2California Legislative Information. California Revenue and Taxation Code 69.6
How Much You Can Spend on the Replacement
If the replacement home costs the same as or less than what your original sold for, your full assessed value transfers with no adjustment. “Equal or lesser value” is defined by when you buy:1California State Board of Equalization. Proposition 19
- If you buy the replacement before you sell the original, it must cost no more than 100% of the original’s sale price.
- If you buy within one year after the sale, it can cost up to 105%.
- If you buy in the second year after the sale, it can cost up to 110%.
Go over those thresholds and you still get a partial benefit. Your new assessed value equals your old base plus the difference between the two homes’ market values, so buying up raises your tax but nowhere near what a full reassessment would.3State Board of Equalization. Prop 19 Base Year Value Transfer Guidance Questions and Answers
Filing the Claim
File form BOE-19-B with the county assessor where your new home is located, not where you sold. Separate forms exist for severely disabled claimants (BOE-19-D) and disaster victims (BOE-19-V).1California State Board of Equalization. Proposition 19
One thing to plan for before you sell: federal capital gains tax. The federal exclusion shields up to $250,000 in gain for single filers and $500,000 for married couples filing jointly, provided you owned and lived in the home for at least two of the five years before the sale.4Office of the Law Revision Counsel. 26 USC 121 – Exclusion of Gain From Sale of Principal Residence Decades of appreciation under Prop 13 can push the gain past those limits.
Deferring Your Property Tax Bill
The State Controller’s Property Tax Postponement (PTP) Program pays your annual property tax bill for you. The deferred amount accrues simple interest at 5% per year and is secured by a lien on your home.5California State Controller’s Office. Property Tax Postponement
Eligibility is narrower than Prop 19’s:
- You must be at least 62, blind, or disabled.
- You must own and occupy the home as your primary residence.
- Total household income cannot exceed $55,181.
- You must have at least 40% equity in the property.
- You cannot have a reverse mortgage on the home.
Applications are accepted each year from October 1 through February 10 and processed in the order received.6State Controller’s Office. California Property Tax Postponement Program
When You Have to Pay It Back
The postponed balance plus accrued interest becomes immediately due when you move out, sell or transfer the property, take out a reverse mortgage, or die without a qualifying spouse or other eligible resident continuing to live there.6State Controller’s Office. California Property Tax Postponement Program PTP is a loan against your home equity, and the balance grows every year. If you intend to age in place and your heirs will sell the property, the math often works. If you are likely to move or need a reverse mortgage later, think twice.
The reverse mortgage rule cuts both ways. Already have a reverse mortgage? You cannot enroll in PTP. Already in PTP and considering a reverse mortgage? Taking one out triggers immediate repayment of the entire deferred balance.
The Homeowners’ Exemption
The Homeowners’ Exemption reduces your home’s assessed value by $7,000, which trims about $70 a year at the 1% base rate.7California Legislative Information. California Revenue and Taxation Code RTC 218 It is modest, but every California homeowner qualifies regardless of age or income, and there is no reason not to claim it.
The property has to be your principal residence on January 1 of the tax year. File a one-time claim on form BOE-266 with your county assessor. Once approved it stays in place until the home is no longer your primary residence. If you have been in your home for years and cannot remember filing, call the assessor’s office and confirm.
Disabled Veterans’ Exemption
If you are a veteran with a 100% service-connected disability rating, or you are compensated at the totally disabled rate, California removes a much larger chunk of your assessed value. For the 2026 assessment year, the basic exemption removes $180,671, and the low-income exemption removes $271,009.8State Board of Equalization. LTA 2025/014 – Disabled Veterans Exemption Increases for 2026 These amounts adjust for inflation annually. At the 1% base rate, the basic exemption alone is worth roughly $1,807 a year.
You must own and occupy the home as your principal residence on the lien date. Unmarried surviving spouses of qualifying veterans can also claim it. You cannot stack this with the standard Homeowners’ Exemption on the same property; you pick one, and the Disabled Veterans’ Exemption is almost always the better choice.
Home Modifications That Don’t Trigger Reassessment
Most home improvements add to your assessed value. Two categories that matter to seniors do not.
Accessibility Improvements
If a permanently and severely disabled person lives in the home, modifications that make the dwelling more accessible are excluded from reassessment. Wheelchair ramps, widened doorways, grab bars, and roll-in showers all qualify, as long as the feature specifically adapts the home for the disabled resident and is not standard in comparable homes.9California Legislative Information. California Revenue and Taxation Code 74.3
To claim the exclusion, the disabled person (or their spouse or legal guardian) submits two documents to the county assessor: a physician’s statement certifying the disability and identifying accessibility needs, and a description of the modifications. The disabled resident does not have to be the owner.
Seismic Retrofitting
Structural strengthening, work to prevent falling hazards from parapets or cladding, and other earthquake mitigation improvements are excluded from reassessment. Unrelated upgrades done alongside the seismic project, such as new plumbing or electrical, are not covered.10California Legislative Information. California Revenue and Taxation Code 74.5
Notify the county assessor before completing the project or within 30 days after. Your contractor, engineer, or architect certifies which portions are seismic retrofitting, and the building department reports those costs to the assessor. Get the paperwork lined up before the project wraps.
Passing the Home to Your Children
Proposition 19 sharply narrowed the parent-child exclusion in February 2021, and this is where planning ahead matters. A parent-to-child transfer of the family home avoids reassessment only if the child moves in and makes it their own primary residence within one year of the transfer, and files for the Homeowners’ Exemption or Disabled Veterans’ Exemption on the property within that same year.11California State Board of Equalization. Proposition 19 Fact Sheet If the child does not live in the home, it gets reassessed to current market value. No exceptions.
Even when the child does move in, there is a value cap. The exclusion protects the existing assessed value plus an inflation-adjusted buffer, currently $1,044,586 for transfers between February 16, 2025 and February 15, 2027.11California State Board of Equalization. Proposition 19 Fact Sheet Anything above that is added to the child’s new tax base. In high-appreciation neighborhoods, expect a real tax increase even when the exclusion applies. Talk to a tax professional before the transfer, not after.
Challenging an Over-Assessment
If your home’s assessed value looks higher than what it would actually sell for, you can file an assessment appeal with your county’s Assessment Appeals Board. Market downturns, neighborhood changes, and property-specific issues like deferred maintenance can all pull real value below the assessor’s number.
The regular filing period opens July 2 each year. Deadlines vary by county, with some closing around September 15 and others extending to November 30, so confirm with your county assessor. Bring evidence: recent comparable sales, an independent appraisal, or documentation of conditions that reduce value. Filing the appeal costs nothing, and if the board agrees, your assessed value drops, sometimes retroactively for the year in question.
Which Program to Prioritize
The right combination depends on what you want to do next.
Staying put on a tight budget? PTP keeps the tax collector at bay as long as you meet the income and equity thresholds and can live with the growing lien. Layer the Homeowners’ Exemption on top; a lower assessment means less tax deferred and less interest piling up.
Downsizing or moving elsewhere in California? Prop 19’s base year transfer is usually the single most valuable thing on this list, especially if you have owned the home for decades. File BOE-19-B with the assessor in the county you are moving to, and plan for the federal capital gains exposure before you sell.
Planning to leave the home to your children? Understand the new parent-child rules now. A child who does not intend to live in the property will face full reassessment, and even one who does may see a tax increase in a high-value area.
A disabled veteran who has never claimed the exemption? That is the fastest, highest-impact filing on this list.
