Property Tax Calculator by County

Find property tax calculators for major US counties. Estimate your property taxes by county and state.

Why Use a County-Specific Property Tax Calculator?

Property tax rates vary significantly by county within the same state. For example, in California, Los Angeles County has a different tax rate than Orange County or San Diego County.

Using a county-specific calculator ensures you get the most accurate estimate based on your local tax rate, assessment ratios, and available exemptions.

We currently offer property tax calculators for 43 major US counties across 13 states. More counties are being added regularly.

How County Property Tax Rates Are Determined

County property tax rates are determined by local taxing authorities, including:

  • County government (general services, roads, libraries)
  • School districts (often the largest portion of property tax)
  • City/municipal government
  • Special districts (fire, water, sewer, parks)

Factors That Affect County Property Tax Rates

Several factors influence how much property tax you pay in a specific county:

  1. Assessed Value: How much your property is worth according to the county assessor.
  2. Tax Rate (Mil Rate): The rate at which your property is taxed, expressed as dollars per $1,000 of assessed value.
  3. Exemptions: Reductions in taxable value for which you qualify (homestead, senior, veteran, etc.).
  4. Special Assessments: Additional taxes for specific local improvements (sidewalks, streetlights, etc.).

How to Lower Your County Property Tax Bill

If you believe your property tax bill is too high, you have options:

  • Appeal your assessment: If you believe your property is overvalued, you can appeal to the county board of equalization.
  • Apply for exemptions: Make sure you're receiving all exemptions for which you qualify.
  • Check for errors: Review your assessment notice for factual errors (wrong square footage, incorrect lot size, etc.).
  • Compare with neighbors: If similar homes in your neighborhood are assessed at lower values, you may have grounds for an appeal.
