What's in Your Riverside County Property Tax?

Your Riverside County property tax isn't one number — it's the 1% Proposition 13 base plus a stack of voter-approved bonds that depends on your Tax Rate Area. Pick your city below to browse its Tax Rate Areas, then open a Tax Rate Area to see every ad-valorem charge, what agency levies it, and what it funds.

Frequently Asked Questions

What makes up my Riverside County property tax rate?

Every parcel pays the 1% Proposition 13 base levy. On top of that, your Tax Rate Area adds voter-approved bond debt for the agencies that serve it — your school district, community college, water districts, and the Metropolitan Water District. The exact mix depends on your Tax Rate Area, so two homes in the same city can pay slightly different rates.

What is a Tax Rate Area (TRA)?

A Tax Rate Area is a geographic zone with a unique combination of overlapping taxing agencies. Riverside County has over 4,000 of them. Your TRA number is printed on your county tax bill, and it determines which voter-approved bonds are added to the 1% base.

Does this include Mello-Roos or direct assessments?

No. The rates here are ad-valorem only (a percentage of assessed value). Mello-Roos / Community Facilities District special taxes and other fixed direct assessments are billed separately as flat charges and are listed under 'Direct Assessments' on your Riverside County bill.

Why is my rate different from my neighbor's?

If your neighbor is in a different Tax Rate Area, different school, water, or city bonds apply, so your ad-valorem totals differ even on the same street. Open your city below and find your exact TRA (from your bill) for its itemized breakdown.
