For the first time, Santa Clara County homeowners who think the assessor overvalued their property have to pay $290 — nonrefundable, win or lose — to file a formal appeal before the Sept. 15 deadline.

A quiet February vote turned one of California's last free property-tax appeals into one of its most expensive. The Board of Supervisors unanimously approved a nonrefundable $290 charge for single-family homes, condos, townhomes, small multifamily, and vacant or agricultural land, plus $675 for commercial, industrial and larger apartment properties. The fees took effect June 1, so this summer's appeal window — which closes Sept. 15 — is the first that costs money to enter. County leaders call it overdue cost recovery amid a budget crisis; critics call it a charge that penalizes residents for questioning the government's own math.

A bare thread on the r/santaclara subreddit this week — one South Bay owner asking how to appeal a property tax assessment — is a small window onto a change most homeowners won't notice until they hit the paywall. As of this appeal season, formally disputing the county assessor's valuation is no longer free.

Per the county's assessment appeals office↗ (external source, opens in a new tab), it now costs $290 to file a formal appeal of the assessed value on a home or condo — the figure that sets an owner's annual tax bill. The same $290 covers townhomes, buildings of four units or fewer, and vacant or agricultural land; owners of commercial, industrial and larger apartment properties pay $675. The charges began June 1, 2026, and the formal filing deadline is Sept. 15. Crucially, the fee is nonrefundable whether the appeal wins or loses.

The Board of Supervisors adopted the fees on a unanimous Feb. 10 vote, as reported by the nonprofit newsroom San José Spotlight. The assessor — who actually sets the values — didn't request them; the push came from the county clerk, whose staff process the filings. County Executive James Williams framed the move as cost recovery under fiscal strain, telling that outlet the county is reworking fee schedules to make programs self-funding as federal support shrinks and a projected $470 million shortfall looms next year. The fees are expected to raise roughly $3.4 million a year — close to the $3.5 million it costs to run the appeals operation.

Williams' argument rests on a mismatch: the county runs the appeals machinery but keeps only a sliver of the tax. He told supervisors most of every property-tax dollar is routed to schools and community colleges, with the rest split among cities and special districts, leaving the general fund to absorb the system's overhead.

The sharper fight was over who a flat fee actually falls on. Supervisors declined to refund the charge even when a homeowner wins. Supervisor Susan Ellenberg argued the county's analysis consumes staff time in every case, successful or not, so the money stays with the county regardless of outcome — turning a $290 filing fee into the price of being told no. In one of dozens of letters residents sent the board, licensed Realtor Milo Abadilla called the amounts unreasonably high and a serious barrier for owners trying to challenge an inaccurate assessment. The recurring objection is structural: the appeals process is already funded through existing taxes, so a large upfront, nonrefundable charge reads to critics as billing residents twice for the same service.

By California standards the pricing is steep. Los Angeles County charges around $50 to appeal and San Francisco about $120; Santa Clara vaulted from nothing to among the state's highest in a single vote. County officials counter that a surge of filings — driven partly by third-party firms that solicit owners and take a cut whether or not an appeal yields savings — has swamped the staff who handle legitimate cases, and that the fee is meant to make the program pay for itself.

There is still a free path, and it now matters more. As the appeal-analysis service Overassessed lays out↗ (external source, opens in a new tab), owners can first request a no-cost informal "decline-in-value" review from the Assessor's Office — deadline Aug. 1 — with results typically returned by mid-August, in time to decide whether to pay for a formal appeal by Sept. 15. The new fee, in other words, lands hardest on owners who skip or miss the free review and go straight to the formal board. Supervisors ordered a one-year study of the program and left room for a sliding scale for small businesses that can't absorb the $675 charge. For a homeowner holding a June assessment notice, though, the calculus is now blunt: pay $290 to argue you were overcharged, and forfeit it even if you're proven right.
