Prop 19 Filing Guide for Santa Clara County

To claim a Proposition 19 benefit on a Santa Clara County property, you file with the Office of the Assessor, County of Santa Clara, at 130 West Tasman Drive, San Jose, CA 95134. Use BOE-19-B to carry your tax base to a replacement home if you are 55 or older. Use BOE-19-P or BOE-19-G plus BOE-266 to claim an inherited family home. Santa Clara County charges a $110 non-refundable processing fee on a base year value transfer claim, which most California counties do not.

That fee is the single most surprising thing about filing here. Budget for it, and do not let it deter you. A transfer that saves several thousand dollars a year is worth $110.

Which Form Do You File?

Proposition 19 provides two separate benefits on two separate tracks.

You are moving to a new home. File BOE-19-B if you are 55 or older, BOE-19-D with BOE-19-DC if you are severely and permanently disabled, or BOE-19-V if a wildfire or Governor-declared disaster destroyed your home. Santa Clara County offers BOE-19-B through an online form flow rather than a plain download.

You inherited a home. File BOE-19-P for a parent-to-child transfer or BOE-19-G for a grandparent-to-grandchild transfer, plus BOE-266 for the homeowners’ exemption. The county posts BOE-19-P here.

The homeowners’ exemption has its own online claim form, which is the fastest way for an heir to satisfy the twelve-month requirement.

The $110 Fee

Santa Clara County charges a non-refundable $110 processing fee on a Proposition 19 base year value transfer claim. The county states it on its Proposition 19 page.

Two points follow from that.

Non-refundable means non-refundable. If your claim fails because you did not meet a condition, the fee does not come back. Confirm you qualify before you file. You must be 55 or older, severely disabled, or a disaster victim. Both homes must be your principal residence. The sale and purchase must fall within two years of each other.

It applies to the transfer claim, not the inheritance claim. An heir filing BOE-19-P and BOE-266 is not the person this fee is aimed at.

Where to File in Santa Clara County

File with the assessor of the county where the property sits. An inherited Santa Clara County home is filed here. A base year value transfer goes to the county of your replacement home. Sell in San Jose and buy in Sacramento, and Sacramento gets the claim, with no $110 fee. Sell in Alameda County and buy in Palo Alto, and it comes here, fee included.

The assessor works out of a single campus at 130 West Tasman Drive in north San Jose. The Department of Tax and Collections sits next door at 110 West Tasman Drive, which is where tax bills are paid, not where claims are filed.

Different questions go to different units. The Property Transfer Unit at 408-299-5540 handles change in ownership questions. The Exemptions Unit at 408-299-6460 handles the homeowners’ exemption. Calling the right one saves a transfer.

The Deadlines That Decide the Outcome

One year, for an inherited home. Move in and file BOE-266 within one year of the date of death. Santa Clara County probate can easily outlast that window, so do not wait for it.

Three years, for the exclusion claim. File BOE-19-P or BOE-19-G within three years of the transfer, or before the home is sold outside the family, whichever comes first. File BOE-19-B within three years of buying or completing the replacement home.

Two years, for the move. Buy and sell within two years of each other, in either order.

Six months, if a supplemental notice arrives. A claim filed within six months of that notice still counts as timely.

Santa Clara Runs a Shorter Appeals Window

Most California counties accept regular assessment appeals from July 2 through November 30. Santa Clara County closes on September 15.

That is ten fewer weeks than a homeowner moving from another county would expect. If the assessor’s value on an inherited home looks too high, the Clerk of the Board takes the application, reachable at 408-299-5088.

The county also runs an informal Proposition 8 decline in value review from June 30 to August 8, which is faster and cheaper than a formal appeal when the disagreement is modest.

Neither process substitutes for filing your Proposition 19 claim. Do both.

Finding Your Factored Base Year Value

Your factored base year value is the number the county taxes today. It is the original purchase price plus annual inflation adjustments capped at two percent, plus the assessed value of improvements. In Santa Clara County, where homes bought in the 1980s now sell for many times their purchase price, the gap between the two numbers is enormous.

Use the county’s property search by map, or read the assessed value off your annual bill. Pay bills through the Department of Tax and Collections.

A Worked Example

A parent dies owning a home in Sunnyvale. The factored base year value is $220,000. The market value on the date of death is $2,100,000. A daughter inherits and moves in within nine months.

The value limit is $220,000 plus $1,044,586, which is $1,264,586. The home exceeds it by $835,414, so the county adds that excess to the base.

• New taxable value: $220,000 plus $835,414, or $1,055,414. Roughly $10,554 a year at one percent.
• Without the exclusion: $2,100,000, or roughly $21,000 a year.

The exclusion is worth about $10,450 a year, and the shortcut confirms it: $2,100,000 minus $1,044,586 equals $1,055,414.

This is the Santa Clara pattern. Home values here often exceed the value limit by a wide margin, so the exclusion rarely delivers complete protection. It still cuts the bill roughly in half, and it still requires the daughter to move in within twelve months and file both forms.

If You Are Leaving Santa Clara County

A base year value transfer is filed with the assessor of the county where your replacement home sits, not with Santa Clara. Sell here and buy in the Sacramento region, and your BOE-19-B goes to the receiving county. Santa Clara’s remaining job is to certify your base year value for them, so request that certification as soon as you close.

That move is common enough to plan for. A Santa Clara County seller usually buys something larger for less money inland, and when the replacement home costs the same or less than the one you sold, your base year value transfers with no adjustment at all.

• Buying in Roseville, Rocklin, Lincoln or Auburn: Placer County
• Buying in El Dorado Hills, Cameron Park or Placerville: El Dorado County
• Buying in Davis, Woodland, West Sacramento or Winters: Yolo County
• Buying in Vacaville, Fairfield, Benicia or Vallejo: Solano County
• Buying in Tracy, Manteca, Lathrop or Mountain House: San Joaquin County
• Buying in the city or county of Sacramento: Sacramento County

The guide to moving from the Bay Area to Sacramento covers the value comparison, the five and ten percent timing cushion, and the certification that travels between the two counties.

Mistakes That Cost Santa Clara Families the Exclusion

Not budgeting for the $110 fee. It is non-refundable, so confirm eligibility first.

Assuming appeals run to November 30. Santa Clara closes on September 15.

Waiting for probate. The twelve-month occupancy clock starts at the date of death.

Expecting full protection on a high-value home. Above the value limit, only the excess is reassessed, and in this county the excess is often large.

Assuming a rental qualifies. Proposition 19 covers a family home the heir occupies, and a family farm. Nothing else.

• Call the Property Transfer Unit at 408-299-5540 or the Exemptions Unit at 408-299-6460, not the general line.
