Riverside County property tax calculator 2026

How it works

In Riverside County, property is assessed under California’s acquisition-value system established by Proposition 13. Assessed value is generally based on the purchase price or value at new construction and may increase by no more than 2% per year unless there is a change in ownership or new construction. Property tax is calculated by multiplying the assessed value by the 1% statewide base rate, plus any additional voter-approved local rates applicable to the property’s Tax Rate Area. The calculation structure is assessed value × total decimal rate.

Examples

In Riverside County, the assessed value used for property tax is typically tied to the property’s acquisition value and may increase within statutory limits each year. If the current assessed value is 690,000, applying the 1 percent general levy would produce 6,900 prior to additional voter-approved obligations. The total effective rate depends on the assigned tax rate area.

Limitations and important notes

This calculator provides an estimate only. In Riverside County, total property tax rates vary by Tax Rate Area due to differing voter-approved bonds and special district charges. The homeowner’s exemption reduces assessed value by 7,000 for qualifying principal residences but requires a filed claim. Supplemental assessments may apply after ownership changes. The actual tax bill may differ from this estimate.
