OC Property Taxes Estimate the property taxes for any Orange County home your are interested in buying.

Step 1: Find Parcel Number: Search by address to find the parcel number; or skip to Step 2 if you know the parcel number.

Step 2: Tax Summary: Click on the parcel number or enter the parcel number to pull up the tax summary.

Step 3: Detailed Tax Bill: Click on "Click Here For Details" (bottom right) to display the existing tax bill.

Step 4: View Existing Property Tax Bill and utilize the basic levy rate & Mello-Roos (if applicable) to estimate property tax obligation at your new proposed purchase price.
 
Step 5: Calculate Baseline Tax Rate: The top few rows all indicate basic tax rates starting with the standard 1.00% basic levy rate for Orange County.  Add all "tax rates" in the second column to arrive at the tax rate for a particular parcel number.  Multiply the combined tax rate by the proposed purchase price (i.e.: $550,000 x 1.068% = $5,874).

Step 6: Calculate Special Assesments:   You will find Special Assessments listed under the "***Special Assessment User Fees***" row.  These values (including mello-roos) will remain the same even after transfer of ownership.  Add all special assessments for Total Special Assessment Fees.

Step 7: Calculate Combined Property Taxes: Add Total Basic Tax Obligation to Total Special Assessment Fees to arrive at a combined estimated property tax obligation based on your proposed purchase price.
