Supplemental Tax Estimator

The Supplemental Tax Estimator provides an estimate of the amount of supplemental taxes you can expect to pay if you have recently purchased a property. Please note that the estimator is intended for changes in ownership only and not for new construction.

There are a number of situations in which the Supplemental Tax Estimator will not be able to produce a reliable estimate. The most common are:

The property owner is responsible for the supplemental bill(s) and, in the event of an impound account, should verify with the lender regarding who should make the actual payment.

For additional information regarding Supplemental Taxes, please visit the Supplemental Assessments page. This estimate is provided as a service by the Riverside County Assessor-County Clerk-Recorder to assist taxpayers in planning for supplemental taxes. Please note that this is an ESTIMATE only and your actual tax bill may be different. It is not intended as a legal notice of supplemental taxes due.
