Tenth Street Place & Assessor's Office Open

Tenth Street Place Public lobbies and the Assessor’s Office Public Counter have reopened. Building Security is monitoring and limiting the occupancy load of the building. This could cause a delay in entry depending on number of people visiting the building at the time you are there. We still strongly encourage the public to take advantage of Assessor online services and receive services by telephone if that is possible.

Customer Service

During the recent Tenth Street Place building closure, the Assessor’s Office effectively delivered all essential services to customers through our website, by phone, facsimile and email. We still encourage you to explore this website for answers to your questions and to find most of our required forms. If you have questions or wish to speak with someone, please give us a call at (209) 525-6461. Our telephone and counter hours are 8:00 AM to 4:30 PM Monday through Friday.

2020 Property Statements

May 6, 2020 - The governor has extended the final filing deadline to May 31st. Because May 31st is a Sunday, the due date falls on the following business day, June 1, 2020.
See Executive Order N-61-20
All Property Statements are now subject to penalty after June 1, 2020.   (This date has been extended from the usual date of May 7th by the governor. Any changes to this date, if authorized by the State of California will be posted to this webpage.)

We encourage taxpayers to take advantage of our online property statement options.

For more information access Personal Property under Assessments on our main webpage, or contact our Business Property division.

2020 Annual Exemption Claims

All annual exemption claim filings were due on February 18, 2020.  If you missed the February 18th deadline, you may still qualify for a partial exemption.

As the elected Assessor of Stanislaus County, it is my sworn responsibility to uphold the State's Property Tax Laws. Our website is an ongoing part of my commitment to keeping you informed of your rights and responsibilities as property owners in Stanislaus County.

Thank you for your understanding during our closure to the public. To contact our office please call (209) 525-6461, 8:00 AM to 4:30 PM, Monday through Friday.

About Us

Who We Are

The Assessor is primarily responsible for preparing an annual assessment roll upon which property tax revenues are generated. The County, Public Schools, Cities, Redevelopment Agencies, and Special Districts all rely on this revenue for funding operations.

What We Do

All property, excluding supplies, movable equipment, boats, and aircraft, are assessed based upon their market value when purchased or newly constructed. The Assessor determines the market value for the ownership changes and new construction. The supplies, movable equipment, boats, and aircraft are assessed based upon their annual market value on January 1 of each year. The Assessor also maintains property parcel maps. These maps are available to the public in the Assessor's Office or at the County's web site (http://www.stancounty.com/assessor/mapbooks). The property tax assessment roll, property ownership information, and some property characteristics are also available to the public at the Assessor's Office.

What We Offer

The mission of the Stanislaus County Assessor's office is to produce a fair, accurate and timely assessment roll while providing excellent customer service.
Fee-based annual data subscriptions are also available. See "Assessor Services" for more information.
The Assessor's Office is open Monday-Friday, 8:00 am to 4:30 pm.
