Sacramento County property tax appeals for 2026

Sacramento County homeowners can challenge an enrolled value when the property's market value as of January 1, 2026 is lower than the assessed value on the roll. The main homeowner filing option is a Decline in Value appeal, also known as temporary Proposition 8 relief.

The county's Clerk of the Board page lists the 2026 Annual Filing Period for Decline in Value as July 2, 2026 - November 30, 2026 and says Sacramento accepts paper applications submitted to the Assessment Appeals Board at 700 H Street, Suite 2450, Sacramento, CA 95814. The same page lists a $30.00 nonrefundable processing fee and explains that the board's principal function is to determine full value or other assessment matters within its jurisdiction. See the county's Assessment Appeals page.

What makes a Sacramento County Decline in Value appeal worth reviewing?

A Decline in Value appeal is about market value on January 1, 2026, not your neighbor's assessment, last year's bill, or general frustration with taxes. The strongest case usually starts with comparable open-market sales showing that similar properties were selling below your enrolled value near the lien date.

Sacramento County Assessor guidance explains that if a property's January 1 market value is below its assessed value, the Assessor may temporarily reduce the assessed value to market value. The same guidance notes that these are often called Proposition 8 reductions and that once such a value is enrolled, it is reviewed each year and can move up or down with market value until it reaches the Proposition 13 cap.

Evidence TaxSauce helps organize

TaxSauce helps homeowners organize a comparable-sales packet around the property, the January 1, 2026 value date, and the county's hearing expectations. A practical packet includes:

• The subject property address and parcel identifier.
• Your opinion of value as of January 1, 2026.
• Three best comparable sales when available.
• Sale date, sale price, address or APN, and distance from the subject.
• Living area, lot size, year built, bedrooms, bathrooms, condition, quality, and amenities.
• Adjustments or notes for meaningful differences.
• Photos or condition evidence when physical condition is part of the value argument.

Sacramento's hearing-preparation guidance says comparable sales are one traditional approach to establishing fair market value and that sales data used as comparables must have occurred no later than 90 days after the lien date. It also says evidence about taxes or assessed value on other property will not be considered. See the county's Preparing for Your Hearing PDF.

Because Sacramento County does not publish a fixed percentage tolerance for living area, lot size, age, or a mandatory countywide distance radius, TaxSauce uses a conservative standardized screen: look for the closest and most similar arm's-length sales, normally within 5 miles, and prioritize sales closest to January 1, 2026. This screening rule helps organize research; it is not a guarantee that the board will accept or reject any particular sale.

Filing steps and hearing expectations

Sacramento County requires the county-specific BOE-305-AH Assessment Appeal Application. You may fill the application electronically, but the county says it accepts paper applications, so the filing should be an original signed paper filing. TaxSauce can help prepare and organize the information, but the homeowner reviews, signs, and submits the filing.

Do not assume that attaching evidence to the application is enough. Sacramento's hearing-preparation guidance says not to submit evidence with the assessment appeal application for board consideration and instructs applicants to bring hearing materials for the board. It also says filing an assessment appeal does not relieve the taxpayer of the obligation to pay property taxes on time. See the county's hearing-preparation guidance.

How savings are estimated

For conservative estimates, TaxSauce uses 1.00% as the effective tax rate for Sacramento County appeal modeling. That reflects California's statewide base ad valorem rate under Proposition 13. Sacramento County's Assessor explains that under Proposition 13, the property tax rate is fixed at 1% of assessed value plus any voter-approved assessment bond. See the Assessor's Proposition 13 explanation.

Actual Sacramento County tax bills can include voter-approved debt rates, direct charges, special assessments, and other items that vary by tax-rate area. Some bill items may not change when assessed value changes, so an appeal-savings estimate is a planning estimate, not a promised refund.

Local volume context

Sacramento County has meaningful appeal activity, but formal appeals are still a small share of total assessments. The Sacramento County Assessor's 2025 Annual Report lists 3,596 assessment appeals filed in 2024-25, representing 0.7% of 536,950 total assessments. It also lists 691 requests for review for 2024-25. See the 2025 Assessor Annual Report.
