California Property Tax Appeal
How to Appeal Your Property Taxes in Santa Cruz County (2026)
Santa Cruz County pairs a coastal lifestyle market — the beach towns of Santa Cruz and Capitola — with spillover demand from over-the-hill Silicon Valley commuters. That mix keeps prices high, and when a neighborhood cools after a run-up, the assessed value on your bill can sit above what homes there actually fetch.
Santa Cruz is one of the more convenient counties to appeal in: alongside mail and in-person filing, it offers an online appeal portal, with a $50 filing fee and a November 30 deadline. The informal Proposition 8 (Decline-in-Value) request runs on a tight clock — roughly 60 days from the mailing date of your assessment notice — so it pays to act as soon as your notice arrives.
This page walks through the Santa Cruz County process — the November 30 deadline, the form, the $50 fee, and the informal-first path — plus an honest take on whether your home is genuinely overassessed.

Is your Santa Cruz County home overassessed?
California property tax bills run roughly 1.1%–1.25% of a home's assessed value. At that rate, an assessment that's $50,000 too high costs a homeowner on the order of $550–$625 every single year — and it compounds until someone corrects it.
The only way to know is to compare your assessed value against what similar nearby homes actually sold for. That's exactly what a Numa analysis does: real comparable sales, an honest overassessed / fairly-assessed verdict, and a conservative savings estimate — for $9.99, with 3 years of monitoring included.
How to appeal in Santa Cruz County, step by step
- 1
Confirm your home is overassessed
Your case rests on recent sales of comparable homes. Gather a few similar properties nearby that sold recently, adjust for differences in size, age, and condition, and check whether they came in below your assessed value. This is the most time-consuming part of an appeal, and the quality of those comparables is what decides it.

Request an informal review with the Assessor
In Santa Cruz County, start with an informal Decline-in-Value (Proposition 8) review — often the fastest path, resolved without a hearing. Contact (831) 454-2002 for the informal review process..
- 3
File a formal appeal if needed
If the informal review doesn't resolve it, file form BOE-305-AH with the Assessment Appeals Board — before the November 30 deadline. You can file online, by mail, or in person.

Present your evidence
Your comparable-sales evidence is what wins the appeal. Numa's $24.99 packet assembles it into a ready-to-file case — and if the informal review fails, the formal Appeals Board packet is included at no extra charge.
Do it yourself, or let Numa do the hard part
You can absolutely appeal on your own — the deadline, form, and steps above are all you need to file. The catch is Step 1: building the comparable-sales evidence that actually wins. Here's the honest trade-off.
Do it yourself
- Free
- Typically 5–10 hours of work
- You find, adjust, and score the comps yourself
- Amateur evidence is the top reason appeals fail
- No easy way to know if you should file at all
