Property Tax Deadline for Riverside County Property Owners

Property Tax Deadline for Riverside County Property Owners

Should Submit the Second Installment of Their Property Taxes Before Due Date to Avoid Penalties 

Riverside, CA – Riverside County's Treasurer-Tax Collector (TTC) Matthew Jennings is notifying property owners that all secured property tax bills were mailed on or before November 1, 2023, in accordance with the Revenue and Taxation Code. Property owners are encouraged to pay the second installment by Wednesday, April 10, 2024, to avoid being assessed a 10% penalty in addition to an applicable administrative cost.

"Property owners were notified of the second installment during our annual mailing in October," stated TTC Jennings. "I encourage those property owners to utilize the various options available, such as the secure online payment system at or using the toll-free automated payment line 877-RIVCOTX (1-877-748-2689) or calling 951-955-3900."

Property tax bills were sent out to all property owners at the address on the tax roll. If the property is owned within the County of Riverside and you did not receive a bill by November 1, 2023, contact the Riverside County Treasurer–Tax Collector’s office immediately. Failure to receive a bill does not relieve the liability to pay taxes nor the addition of penalties attached by law.

The first installment of the 2023-2024 fiscal year taxes was due and payable on November 1, 2023, and became delinquent if it was not paid by December 11, 2023.  The second installment of the 2023-2024 fiscal year taxes were due and payable on February 1, 2024, and will become delinquent if they are not paid by April 10, 2024.

Payment for both installments could be made on or before the first installment is due; however, the second installment can only be paid separately once the first installment is paid.
