California Property Tax Appeal
How to Appeal Your Property Taxes in Sacramento County (2026)
Sacramento County anchors California's capital region, where steady government employment has kept the housing market a little calmer than the coast — but calmer isn't the same as correctly assessed. When prices dip in a pocket of the county, the value on your tax bill doesn't automatically follow them down.
Sacramento is unusually generous on the informal side: the Assessor offers a free Proposition 8 (Decline-in-Value) review from July 1 through December 31 — a wide window to make your case at no cost before you ever file a formal appeal. If comparable homes near you sold for less than your assessed value, that free review is the obvious first step.
Below is how the whole Sacramento County process works — the November 30 formal deadline, the form, the $30 fee, and that free informal window — along with an honest verdict on whether you're overassessed at all.

Is your Sacramento 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 Sacramento 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 Sacramento County, start with an informal Decline-in-Value (Proposition 8) review — often the fastest path, resolved without a hearing. Contact (916) 875-0700 for the informal review process..

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 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
