Each year, the Treasurer-Tax Collector's Office mails in excess of 700,000 property-tax bills and informational copies to owners of property in Riverside County. These annual property-tax bills cover the period from July 1 to June 30 and reflect the assessed value of the property as of January 1st.

Property tax bills are mailed out in late September/early October and are payable in two equal installments. To avoid late-payment penalties, the first installment must be paid by December 10th, if not a weekend or holiday; and the second installment by April 10th. If the 10th falls on a weekend or holiday, the installment must be paid by the next business day. A postmark date before the delinquency date is sufficient.

There is no provision under state law for an extension of time in which to pay your current-year property taxes without a penalty. If your payment is late, a 10 percent penalty (as required by state law) will be charged on each late installment paid. For payments not received by June 30th, an additional penalty of 1.5 percent per month (an annual percentage rate (APR) of 18 percent) will be charged on the taxes owed.

If you have not received your annual tax bill by early November, you should call the Treasurer-Tax Collector's Office to request a duplicate bill. Failure to receive a tax bill does not excuse you from your tax obligation.

If you have a touch-tone telephone and know the parcel number of the property, you may call the Treasurer-Tax Collector's automated 24-hour information line at (951) 955-3900 to obtain a duplicate bill.

State law requires the Treasurer-Tax Collector to provide an information copy of the tax bill to each property owner who has an impound account. In the event that your loan has been paid off, or you have acquired a new loan, you can use this informational copy to pay your taxes.
