INSTRUCTIONS
Section 51 of the California Revenue and Taxation Code provides that the assessed value of any real property shall not exceed its market value on the January 1 lien date. If you have evidence that the value of your property on January 1, is less than its assessed value, please provide the information requested below and return this form to the assessor's office by MARCH 15. Should March 15 fall on a weekend, holiday, or the county's offices are closed for the entire day, the filing deadline moves to the next business day. Informal Assessment Review forms postmarked or delivered to the assessor's office AFTER THE DEADLINE WILL NOT BE PROCESSED. Applicants will be notified by mail of any late filing. If you have any questions, please contact the assessor's office.
To protect your rights, you should file an Application for Changed Assessment with the clerk of the county board NO LATER THAN [SEPTEMBER 15/NOVEMBER 30] if: (1) you are unable to meet the March 15 filing deadline for this form; (2) you receive the assessor's response to your request for an assessment review before September 1 but disagree with the assessor's value; or (3) you do not receive the assessor's response to your request for an assessment review by September 1.If the board of supervisors in the county in which the real property is located has adopted a resolution in accordance with section 1603 of the Revenue and Taxation Code and if you receive the assessor's value conclusion resulting from your request for an assessment review after September 1, then the deadline for filing the Application for Changed Assessment will be either 60 days after the mailing of the response by the assessor or by December 31 of the year in which the application for Informal Assessment Review is filed, whichever is earlier. You should check with the clerk of the board of supervisors to determine if a section 1603 resolution has been adopted. The normal assessment appeals filing period is from JULY 2 through [SEPTEMBER 15/NOVEMBER 30]. You may request an Application for Changed Assessment after July 2 by calling the clerk of the board of supervisors.
