How to Appeal Property Tax in California (Step-by-Step Guide)
If you believe your home is overvalued, you may be able to reduce your property tax by filing an appeal. Many homeowners in California overpay simply because they never check their assessed value.
This guide explains how to appeal property tax in California, what documents you need, and how to decide if it's worth filing.
Step 1: Check Your Property's Assessed Value
Property tax in California is based on your property's assessed value. Start by reviewing your assessment and comparing it with similar homes in your area.
Step 2: Compare With Nearby Properties (Comps)
Look at recent sales of similar properties in your neighborhood. If your home is assessed higher than comparable properties, you may have a valid reason to appeal.
Step 3: Prepare Supporting Information
You may include supporting details such as:
- Recent comparable sales data
- Photos showing property condition
- Any issues affecting value (damage, outdated systems, etc.)
Step 4: File an Appeal
To appeal your property tax in California, you must file an Application for Changed Assessment with your county's Assessment Appeals Board.
Most counties allow you to submit your appeal online, though paper forms are also available.
California Property Tax Appeal Deadline
In most counties, the regular filing period runs from July 2 to November 30. If you receive a reassessment notice, your deadline may be based on the notice date instead.
Is It Worth Appealing Property Tax?
Not every appeal will result in a reduction. However, many homeowners never check their assessment at all.
Submitting gives you a chance. Not submitting guarantees you miss it.
Check If Your Property Tax Is Too High
Before filing, you can check whether your property tax appears higher than typical homes in your area.
