Deadline to file with Riverside County for unclaimed property tax refunds fast approaching


RIVERSIDE COUNTY – Owners of residential or business property in Riverside County have until Aug. 3 to file for unclaimed property tax refunds.

County Chairman V. Manuel Perez and Treasurer-Tax Collector Jon Christensen issued the reminder to give taxpayers sufficient time to file for refunds and not be caught short by the deadline.

“During these challenging times, it is even more important for these funds to go back to the rightful owners,” Perez said.

Filing instructions and a list of all unclaimed property tax refunds from tax year 2015 and previous years are available on the treasurer-tax collector’s website at

According to Christensen, 609 refunds totaling $651,006.30 remain unclaimed. Most refunds stem from valuation reductions by the county assessor and are related to corrections or cancellations to the tax roll after taxes were already paid.

Under California law, property tax refunds unclaimed for four years after the payment date – or one year after a requested claim form has been mailed back to a taxpayer by the county, whichever is later – may be transferred to the county general fund by order of the board of supervisors.  After Aug. 3, any unclaimed money shifts to the general fund and no longer can be claimed.

Completed claim forms and supporting documentation should be emailed to or mailed to: Riverside County Treasurer-Tax Collector, Attn: Property Tax Unclaimed Refunds, P.O. Box 12005, Riverside, CA 92502-2205.

Submitted by the office of the Riverside County Treasurer-Tax Collector.
