Riverside County Property Tax
The average property-tax rate in Riverside County is about 1.17% of assessed value (Board of Equalization county average, 2024-25) — the 1% Proposition 13 base levy plus each area's voter-approved debt. That's above the statewide average of about 1.11%, making it the 9th-highest of California's 58 counties (the 50th-lowest). On a $500,000 assessed value that's roughly $5,865 a year.

How Riverside County property tax is calculated
California taxes property under Proposition 13: your assessed value is generally set when you buy, then rises no more than 2% a year until the property changes hands or is newly built. The annual bill is that assessed value times the ad-valorem rate — the 1% base plus voter-approved bonds — which is why Riverside County's average works out to about 1.17%. Because the bonds differ by Tax Rate Area, two homes in the same county can pay slightly different rates.
What's on a property tax bill
Ad-valorem tax (1% base + voter-approved debt) · Mello-Roos special taxes, where a parcel is in a Community Facilities District (how long they last) · fixed direct assessments (lighting, sewer, etc.). Only the first is value-based; the 1.17% rate covers that part.
Learn the rules behind the rate: how California property tax is calculated, Proposition 13, Mello-Roos, and what triggers a reassessment.

Riverside County property tax by the numbers
How much is property tax in Riverside County? For an existing owner the average single-family home is assessed near $455,777, so at the county's 1.173% average rate (Board of Equalization county average, 2024-25) the implied bill is about $5,346 a year (a mean across all existing owners, not a median). A new buyer is taxed on the purchase price instead — use the calculator above. The figures below are the county-level activity behind that rate.
Sources: California State Board of Equalization (assessors' workload tables, Table E1 single-family values, property-tax allocation), the California Debt and Investment Advisory Commission (Mello-Roos roster), the California FAIR Plan Association (policies in force by county) and CAL FIRE / OSFM fire hazard severity zones weighted by 2020 housing units. County aggregates only, no parcel or owner identities; counts are filings processed and can lag the event year. Verify with the Riverside County Assessor before relying on them.
Due dates & where to pay
Riverside County property taxes are paid in two installments: first due November 1 (delinquent after December 10) and second due February 1 (delinquent after April 10). A 10% penalty applies after each delinquency date, and a bill still unpaid on July 1 becomes tax-defaulted; after five years in default the county may sell it at auction (see the California tax sale calendar). Boats, aircraft and business equipment are billed separately on the unsecured roll, due in one payment by August 31. Pay or look up a parcel through the Riverside County Treasurer-Tax Collector. Portal links, fees and missing-bill numbers for every county are on one look-up-and-pay page.
These deadlines are set by California state law (Revenue & Taxation Code §§ 2605, 2606, 2617 and 2701) and are the same in every county — this is general education, not a county-by-county check. If a delinquency date falls on a weekend or legal holiday, it moves to the next business day. Always confirm the exact dates and amounts on your own tax bill and your county tax collector's website. See the full California property tax due-date calendar for the dated 2026–27 schedule, penalties, and when bills are mailed.
Ways to lower your bill
- The $7,000 Homeowners' Exemption for owner-occupants (~$70/yr) — not the same as the homestead exemption, which protects home equity from creditors and changes no tax.
- Senior programs — Property Tax Postponement (62+, income-qualified; the state pays the bill at 5% simple interest) and a Proposition 19 base-year transfer (55+).
- A Proposition 8 decline-in-value review if the market drops below your assessed value.
- Appealing your assessment if it looks too high — the regular filing window in Riverside County runs July 2 to November 30 (2026); only the assessed value can be appealed, not the rate or the flat charges.
Selling in Riverside County: the transfer tax
A sale also pays a one-time documentary transfer tax of $1.10 per $1,000 of the price (net of any loan the buyer takes over) to the county (Revenue and Taxation Code §11911), $1,100 on a $1,000,000 sale. In Riverside County the City of Riverside's recorder states one combined city-and-county rate of $2.20 per $1,000, so a sale inside the city pays that figure rather than $1.10 plus a separate city line. Estimate it for any sale with the California transfer tax calculator; the documentary transfer tax guide covers who pays and the exemptions.
Riverside County property tax by city
Typical ad-valorem rate, assessed value and annual bill for the largest Riverside County cities. Each city page has its own calculator and ZIP-level detail.
The city values are medians of single-family homes — the middle home in each city, while the county's average single-family value shown above ($455,777) is a mean across every single-family parcel in the county. A city can sit above or below that figure — the county average also includes the cities not listed here and the unincorporated areas, and the two come from different rolls (the county parcel file vs. BOE Table E1) — so the mean describes the county as a whole, not a typical home in any one city.
| City | Typical rate (most areas) | Median single-family value | Typical bill | Single-family parcels |
|---|---|---|---|---|
| Corona | 1.12% | $514,689 | $5,765 | 41,451 |
| Moreno Valley | 1.13%most areas 1.13–1.14% | $332,527 | $3,758 | 45,838 |
| Murrieta | 1.10%most areas 1.02–1.11% | $507,009 | $5,577 | 34,371 |
| Palm Desert | 1.22% | $513,394 | $6,263 | 17,737 |
| Riverside | 1.11%most areas 1.11–1.23% | $398,457 | $4,423 | 92,607 |
| Temecula | 1.03%most areas 1.02–1.03% | $543,597 | $5,599 | 33,051 |
Rate = the middle (median) ad-valorem rate among the city's parcels, each at its own Tax Rate Area (county Auditor-Controller); "most areas" is the 10th–90th percentile range where it varies. Excludes Mello-Roos and fixed direct assessments. Assessed value = the median assessed value of the city's single-family parcels (county Assessor use codes) on the county roll for existing owners — a Proposition 13 basis, not a sale price. Typical bill = that value × the median rate: an illustrative figure for a middle-of-the-road parcel, not the median of actual bills; your bill depends on your own assessed value and Tax Rate Area. Single-family parcels = the parcels behind each median (county Assessor use codes). County aggregates only; verify with the county Assessor before relying on them.
