ATC Annual Report Highlight

The Tax Collector's office is responsible for the collection of property taxes.

Property Tax Postponement

The program allows homeowners who are seniors, are blind, or have a disability to defer current-year property taxes on their principal residence if they meet certain criteria including 40 percent equity in the home and an annual household income of $45,000 or less. The applications filing period is from October 1 to February 10. Please call (800) 952-5661 or email postponement@sco.ca.gov if you prefer to have an application mailed to you. You may also call our office at (909) 387-8308.

To estimate your new tax bills enter what you know about your property and select the property.



Pay your property taxes conveniently and securely using our website.

FREE eCheck (electronic check) is a digital version of the paper check. The process mirrors paper checks, but is done electronically. The funds are withdrawn from the taxpayer’s bank account (usually a checking account), transferred over the ACH network, then deposited into the Tax Collector’s office bank account. There is no charge to use an electronic check.

To process your payment using a MasterCard, VISA, American Express, or Discover Card, our third party vendor charges a convenience fee of 2.25% (minimum of $1.95) for credit cards. The convenience fee is not retained by the Tax Collector.

The Treasurer's office provides banking services for all County departments who invest in the County Treasury Pool.
Tax Sales Tax-defaulted properties may be purchased through our office via an Online Auction. This tax sale is scheduled for August 6, 2022 through August 12, 2022.
