How Orange County property tax is calculated

Every Orange County bill is 1.00000% of the net assessed value (shared by the county, city, schools and districts) plus the voter-approved debt rates of the Tax Rate Area. The Tax Rate Area code starts with the city prime code: 01 is Anaheim, 11 Santa Ana, 26 Irvine.[1]

Tax = (Assessed value − $7,000) × (1% + TRA bond rates) + Mello-Roos and other fixed charges

The same $900,000 assessed home with the homeowners' exemption pays $9,236.66 in Irvine (26-006), $9,997.22 in Santa Ana (11-002) and $10,147.16 in Anaheim (01-001): $911 a year apart because of school and college bonds.[1]

Orange County property tax rate by Tax Rate Area

The 2025-26 Tax Rate Book lists 34 city prime codes plus school-only codes for unincorporated areas, and some Irvine TRAs are as low as 1.00700% (1% plus the Metropolitan Water District).[1]

Orange County assessment appeals: November 30

Orange County's regular appeal window runs from July 2 to November 30 at 5 p.m., not September 15 as in many California counties, because the Assessor mails a value notice to every owner.[7][8] Start online with the Clerk of the Board, then print, sign and mail or hand-deliver the original before the deadline (no fax). No filing fee. The Assessor also offers informal reviews.[7]

What Orange County homeowners typically pay

Census figures for 2024 put the median property tax paid by Orange County homeowners at $6,436 on a median home value of $1,037,200, an effective rate of about 0.62%.[9][10]

For comparison, Los Angeles County property tax uses the same Prop 13 rules with its own rate areas, and state rates are compared on property tax rates by state.

Common mistakes

  • Mixing up Orange County, CA and Orange County, FL. Florida taxes by millage under its own exemption rules; this page is California.
  • Ignoring Mello-Roos. In newer communities the CFD special tax can be thousands of dollars on top of the rate.
  • Using today's price for an older home. Enter the assessed value from your bill.
