Application for Change in Assessment
Pursuant to the revisions to California State Law, effective January 1, 1993, you are advised that:
If you disagree with a change in the assessed value as shown on your tax bill, you have the right to an informal assessment review for the following tax year by contacting the Placer County Assessor's Office at (530) 889-4300 by January 1 of the current tax year.
If you and the Placer County Assessor are unable to agree pursuant to the informal assessment review on the proper assessed value, you have the right to file an application for reduction in assessment with the Placer County Assessment Appeals Board during the period from July 2 to November 30, inclusive, of the current tax year.
