2017 Exemption and Property Statement Filings

Exemption Claims

All annual exemption claim filings are due February 15, 2017

In the last week of December, the Assessor’s office mailed out annual property Exemption Claim forms to all known claimants. The Welfare Exemption Claim, for qualifying non-profit agencies (including some church properties), the Church Exemption Claim and the Historic Aircraft Exemption Claim, must be filed annually. Our office sends out an annual questionnaire to existing claimants of the Religious Exemption to determine if any information has changed.

As required by law, and as changes in ownership are processed in our office, the Assessor also mails Homeowner Exemption claim forms to all buyers of residential property. In order to qualify for a 2017 Homeowner Exemption, the home must be owner occupied as of 12:00 AM January 1, 2017.

For more information, please see Exemptions under the Assessment menu on our main webpage, or contact our Exemptions Division.

Property Statements

All Property Statements are due April 3, 2017, and subject to penalty after May 8, 2017

Annual Property statement filing requests were mailed to taxpayers at the end of January. All Business owners and existing Agricultural property online filers received an instruction/request letter providing them with a BIN (Business Identification Number) necessary to access our online filing system. Agricultural Property owners who did not previously file online received a paper statement and instructions for online filing, if they should choose to take advantage of this improved service. Owners of apartment complexes, boats and aircraft will only receive a paper statement.

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

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. To contact our office directly please call (209) 525-6461, 8:30 AM to 4:30 PM, Monday through Friday.

Thank you,

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 ( The property tax assessment roll, property ownership information, and some property characteristics are also available to the public at the Assessor's Office.

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.
