How to File
Property Value Reduction: A temporary reduced value, or "decline-in-value" assessment (also called "Prop 8"), occurs when the current market value of your property is less than the assessed value as of January 1. The Assessor reviews thousands of properties each year to ensure that fair and equitable assessments are provided for Riverside County taxpayers. This review encompasses all properties that received a decline in value reassessment last year and applies to the assessed value as of January 1, 2021, for Fiscal Year 2021-22.
If your property does not meet the review criteria above and you believe the value should be lowered, you may file a Decline-in-Value Reassessment Application (Prop. 8). The filing deadline for a Decline-in Value Application is November 1, 2021. There is no guarantee your value will be reduced prior to the first installment date and your taxes should be paid as-is on time regardless of any possible future reduction. For more information, please click here, or find the application under E-Forms on this site.
