To appeal property taxes in Sacramento County, file a paper Assessment Appeal Application with the county’s Assessment Appeals Board between July 2 and November 30, pay the $30 per-parcel fee, and be ready to prove with comparable sales that your property was worth less on January 1 than the Assessor says it was. Before you file, though, try the free informal review with the Assessor’s office. It settles many disputes without a hearing.
Start With the Free Informal Review
The Sacramento County Assessor offers an informal Proposition 8 review each year between July 1 and December 31 at no cost.1Sacramento County Assessor. Assessment Appeals An appraiser looks at your property, makes a determination, and tells you the result. You can also call the Real Property appraisal staff at (916) 875-0700 to talk through your assessed value first.
If the Assessor agrees the value is too high, the roll gets corrected and you save the $30 filing fee and months of waiting. If the informal review doesn’t get you what you want, you still have time to file a formal appeal so long as the November 30 deadline hasn’t passed.
Know Which Kind of Appeal You’re Filing
Decline in Value (Proposition 8)
This is the most common appeal. Under California Revenue and Taxation Code Section 51, your taxable value each year is the lower of your base year value (trended up by no more than 2% annually) or the property’s current fair market value.2California Legislative Information. California Revenue and Taxation Code Section 51 When the market pushes actual value below the trended base year figure, you’re being taxed on value that isn’t there. A Proposition 8 appeal asks for a temporary reduction to match reality.
The date that matters is January 1, the annual lien date. Your evidence has to show what the property was worth on that date. Once the market recovers and value climbs back above the trended base year, the assessment goes back to the Proposition 13 number.2California Legislative Information. California Revenue and Taxation Code Section 51
Base Year Value Disputes
When you buy a property or trigger a change in ownership, the Assessor sets a new base year value under Proposition 13. If that initial number is too high, you can appeal it. Unlike a Proposition 8 reduction, a successful base year challenge permanently lowers the starting point for future 2% increases.
Disaster Damage Is a Separate Track
If fire, flood, or another disaster damages your property and reduces its market value by at least $10,000, you don’t go through the Appeals Board. You file a claim directly with the Assessor under Revenue and Taxation Code Section 170 within 12 months of the damage, or within the timeframe set by county ordinance, whichever is later.3California State Board of Equalization. Information Guide for Disaster Relief for Damaged Property The Assessor reassesses the property downward on a prorated basis.
Deadlines and How to File
The regular filing window for secured and unsecured assessment appeals in Sacramento County runs July 2 through November 30.1Sacramento County Assessor. Assessment Appeals If November 30 falls on a weekend, an application postmarked the next business day counts as timely. Supplemental, roll correction, and escape assessment appeals work differently: you have 60 days from the mailing date of the tax bill. Miss the deadline and the assessment stands for the year, no matter what the property is actually worth.
Sacramento County only takes paper applications. You can fill out the Assessment Appeal Application online and save it, but you have to print, sign, and mail or deliver the original to the Assessment Appeals Board at 700 H Street, Suite 2450, Sacramento, CA 95814.4Sacramento County Clerk of the Board. Assessment Appeals The fee is $30 per application, non-refundable, due at filing.5Sacramento County Clerk of the Board. County of Sacramento Information and Instructions for Assessment Appeal Application The Clerk issues an application number for tracking once it’s processed.
One box on the form is worth catching: designate the application as a claim for refund. If you don’t, and you win, you’ll have to file a separate claim-for-refund form with the county Board of Supervisors to actually get your money back.6California Department of Tax and Fee Administration.

Keep Paying Your Taxes
Filing an appeal does not pause your property tax bill. You have to pay on time while the appeal is pending, and late payment triggers penalties and interest no matter how the appeal turns out.6California Department of Tax and Fee Administration. Assessment Appeals Frequently Asked Questions California’s automatic late penalty is 10%, and it sticks even when the delay is a day or two. Win your appeal and you get a refund of the overpayment. You don’t get to withhold on the front end.
Build Evidence That Actually Persuades
Pull your Assessor’s Parcel Number and current assessed value off your annual tax notice. The application asks for a specific Opinion of Value, and that number has to be tied to real data.
For residential property, comparable sales are the strongest evidence. The California Board of Equalization treats sales of comparable properties as the best supporting documentation, and your Assessor’s website may offer sales data for properties sold in the last two years.6California Department of Tax and Fee Administration. Assessment Appeals Frequently Asked Questions Look for homes near yours that sold close to the January 1 lien date, matching square footage, lot size, age, and condition as closely as you can.
Lay the comps out side by side with address, sale price, sale date, and features next to your own property. If your house has problems the comps don’t (deferred maintenance, freeway noise, a bad lot shape), document those too. The board evaluates technical evidence, so tight and organized beats thick and scattered.
The Hearing
The Clerk sends written notice of the hearing date, time, and location. Either side can request a formal exchange of information before the hearing, which forces both parties to share the data and valuation methodology they plan to rely on. That request has to be in writing.
Who has to prove what depends on your situation. Usually, the burden is on you to show the Assessor’s value is wrong. But if the property is a single-family home that is your principal residence and qualifies for a homeowner’s property tax exemption, Revenue and Taxation Code Section 167 creates a rebuttable presumption in your favor, and the Assessor carries the initial burden of justifying the valuation, provided you gave the Assessor all information the law requires.7California State Board of Equalization. Burden of Proof That presumption falls away if you failed to file a change-in-ownership statement or skipped a permit for construction that triggered an escape assessment.
At the hearing, a panel of board members hears from you and from the Assessor’s representative. You don’t need a lawyer, but you do need a clear presentation: a defensible opinion of value tied to specific market data, and reasoned adjustments for differences between your comps and your property.
California law requires the board to hear and decide your case within two years of filing. If the board misses that window, your stated opinion of value on the application becomes the assessed value by default. That’s a real protection, and it’s why the number you put on the application matters: pick something reasonable and defensible, because it’s both what you’ll argue for at the hearing and what you’ll get automatically if the board never reaches you.
After the Decision
The board sometimes announces its decision at the end of the hearing. Otherwise you’ll get it by mail, which can take several months depending on caseload and complexity.6California Department of Tax and Fee Administration. Assessment Appeals Frequently Asked Questions A reduction gets you a refund plus interest.
A Proposition 8 win is temporary by design. The Assessor reviews the property’s market value each January 1 and restores the assessment to the trended base year value once the market recovers.2California Legislative Information. California Revenue and Taxation Code Section 51 You don’t have to refile every year the value stays down; the Assessor is required to reappraise reduced properties annually until market value passes the trended base year again.
Should You Hire Someone?
California doesn’t license or regulate property tax agents. There are no state-mandated training or ethics requirements. You can hire an attorney, a CPA, a licensed appraiser, or anyone else you authorize in writing to appear for you. State law does prohibit deceptive advertising and filing an appeal without the owner’s knowledge.
A professional appraisal report can strengthen a case, particularly for higher-value or unusual properties where comps are scarce. Appraisal fees for a tax-appeal valuation generally run several hundred dollars. For an ordinary single-family home in a neighborhood full of recent sales, you can often make a strong case yourself, and the $30 filing fee is the only cost you’re locked into.
