Why do Prop 19 claims get denied?

5 min read · Checked against BOE: 4 November 2026 · [Reviewer: pending attorney review]

Last checked November 4, 2026. A Prop 19 claim is checked against a short list of rules. When a claim is denied or reduced, it is almost always because one of those rules was not met, or the paperwork did not prove it. The good news is that most of these problems can be spotted before you sell. Each reason below comes from the Board of Equalization (BOE) Prop 19 page, its letters to county assessors and the BOE-19-B claim form.

BOE does not publish denial rates by county, so this page does not give any numbers.

The old home was not your principal residence

A rental, a second home or a vacation cabin does not count. BOE says the original home must have been your principal residence, meaning you owned it and lived in it, either at the time of sale or within two years of buying the new home. There is no minimum stay.

The fix: if you did not have the homeowners' exemption, gather proof that you lived there. BOE lists voter registration, vehicle registration, bank accounts and income tax records.

The new home is not your principal residence

The claim form asks if you live in the new home as your principal residence, and you sign that answer under penalty of perjury. BOE says the claim is filed after both sales close and you are living in the new home. It is not done through escrow.

The fix: move in first, then file.

More than two years between the sale and the purchase

The new home must be bought or built within two years of selling the old one, before or after. BOE allows no extension for hardship or construction delays.

The fix: write down both dates before you list. If you buy first, you pay tax on the new home's full value until the old one sells, with no refund for that period. The calculator shows the timing.

You were not 55 on the sale date

BOE is clear: you must be at least 55 on the day the original home sells. Turning 55 before you buy the new home does not help.

The fix: if your birthday is close, time the sale for after it. For married couples, only the spouse who is 55 or older needs to be the claimant, as long as that spouse owns both homes.

You already used your three transfers

Each person can use the 55 or older transfer three times. The form asks for your Social Security number so the state can track the count, and asks where any earlier Prop 19 transfers were granted. A Prop 60 or Prop 90 transfer used before April 1, 2021 does not count toward the three.

The old home was not really sold

Prop 19 needs a sale and a purchase. BOE says a gift or an inheritance is not a purchase. If you sell your home to your child and the child claims the parent-child exclusion, you cannot also move that value to your new home. In a divorce, a transfer to your spouse is not a sale either.

Missing information or no signature

The form says an incomplete claim may not be processed. It needs valid ID with your date of birth, your Social Security number, your signature and the details of both homes. If the old home is in another county, attach its latest tax bill and any supplemental bills issued before the sale.

The fix: use the BOE-19-B form guide as a checklist.

Filed late

You have three years from buying the new home to file. BOE says a late claim can still be granted, but relief starts only with the year you file. There is no refund for the years before.

Filed in the wrong county

The claim goes to the assessor of the county where the new home is. If you move from one county to another, the new county handles it. The filing guide has the steps.

For heirs: nobody moved in within a year

An inherited family home keeps the parent's value only if it becomes a child's principal residence and that child files for the homeowners' exemption within one year of the transfer or death. BOE says a late filing gets the exclusion only going forward. A rental home passed to a child does not qualify at all.

If your claim is denied

BOE says you can appeal to the county assessment appeals board by stating the value the home would have had if the claim had been granted. A base year value can be appealed in the year it is first enrolled and the next three years.
