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.
Riverside County's Tax Rate Areas at a glance (2025/2026)
The 2025/2026 rate book lists 4,159 Tax Rate Areas in Riverside County. The Assessor's roll maps 692,045 parcels to 39 cities and communities (the table below); the 2,103 Tax Rate Areas listed under those communities hold 682,414 of them (the rest sit in Tax Rate Areas too small to list under a community). Their rates run from 1.0175% to 1.3719% of assessed value, with a parcel-weighted median of 1.1295%. Beyond the 1% Proposition 13 base, 52 voter-approved levies apply: 24 water and flood-control levies, 22 school district bonds, 5 community college bonds, 1 hospital district bond.
Two different averages: the 1.1295% above is the parcel-weighted median of the county's own 2025/2026 rate book; the 1.173% on the Riverside County guide is the Board of Equalization's county-average rate (2024-25), a different method and year. Both are ad-valorem only.

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.
