Taxation and Finance California 4 Minutes Read · published February 06, 2026 Flag of California

In San Jose, California, property tax refunds and assessment adjustments are administered by county offices rather than the city. If you believe you overpaid property tax or your assessed value is incorrect, start promptly — deadlines and procedures are time-sensitive. This guide explains which Santa Clara County offices handle refunds and assessment appeals, how to gather evidence, where to submit claims, and practical steps to apply, appeal, pay or report issues so you can resolve a tax overpayment or valuation error affecting property in San Jose.

Who handles refunds and adjustments

Property tax billing, refunds, and liens for San Jose addresses are handled by Santa Clara County departments. Refunds and payment inquiries are administered by the Santa Clara County Treasurer-Tax Collector; assessment value disputes and appeals are handled by the Santa Clara County Assessor and the county Assessment Appeals Board. For official procedures and contact details, see the county Treasurer-Tax Collector and Assessor pages [1][2].

Start early — appeals and refund requests often have strict deadlines.

When to file

  • File as soon as you identify an overpayment or incorrect assessment; some appeals require filing within a statutory window or by the tax year deadline.
  • File an assessment appeal if you disagree with the assessed value; file a refund claim if you have proof of overpayment or duplicate payment.
  • Collect deeds, purchase records, recent appraisals, comparable sales, and tax bills to support your case.
