Using this service provided by the Riverside County Treasurer, you can view your current property tax statements and pay them online. Please note that all tax bills paid online or by the automated phone system are due by midnight on the delinquent date.
If you do not pay the first installment of your annual Riverside County (CA) tax bill by 5 p.m. on December 10, then that installment becomes delinquent, and a 10% delinquent penalty is incurred.
If you fail to pay the second installment by 5 p.m. on April 10, it becomes delinquent and a 10% penalty on the unpaid taxes as well as an administrative charge of $38.63 are added.
Likewise, if you fail to pay any supplemental tax bill installment by the applicable delinquency date, the same penalties and charges accrue as for delinquent annual taxes.
If there are ANY unpaid taxes as of 5 p.m. on June 30, then the property becomes tax defaulted. Once the property has become tax defaulted, a redemption fee of $36.77 and additional penalties begin to accrue at the rate of 1-1/2% per month of the unpaid taxes. This monthly penalty is added at 5 p.m. on the last day of each month (or the following business day if the last day of the month falls on a weekend or holiday).
