Property Tax Calculator
Estimate your annual property tax bill instantly. Enter your home value and select a state or county — we apply real effective rates from official U.S. Census and county data.
Calculate Your Estimated Property Tax
Select your local jurisdiction and enter your home value to instantly estimate your annual tax bill.
Estimate only. Results are based on county effective rates (median taxes ÷ median home value). Your actual bill depends on your parcel's assessed value, special-district levies, and any exemptions you qualify for. Always confirm with your county assessor.
How Our Property Tax Estimator Works
Local governments use complex millage rates and fractional assessments. We simplify everything with a single, transparent effective tax rate.
Enter Home Value
Type in your home's market value or purchase price. You can also use your county assessor's estimated market value.
Select Location
Choose your state or county. We apply the county-level effective rate sourced from U.S. Census ACS 5-year estimates.
Get Your Estimate
Instantly see your estimated annual tax bill, monthly escrow amount, and how your rate compares to state and national averages.
What Is an Effective Tax Rate?
The effective tax rate is calculated as:
Median Annual Taxes ÷ Median Home Value × 100
This reflects what homeowners actually pay — not the nominal millage rate, which is applied to assessed value (often a fraction of market value).
It is the same methodology used by the Tax Foundation and Urban Institute, making our estimates directly comparable across states and counties.
What Changes Your Final Bill?
- Special Districts: School, fire, and utility districts can add extra levies on top of the base county rate.
- Assessment Ratio: Your assessor's valuation may differ from market value, raising or lowering the taxable base.
- Exemptions: Homestead, senior, and veteran exemptions reduce taxable value — sometimes by $50,000+.
- New Construction: Newly built homes often trigger a full reassessment in the first year.
💡 Check Your Exemption Eligibility
Most homeowners qualify for at least one exemption. A homestead exemption alone can reduce your taxable value by $25,000–$100,000 depending on your state. Learn about exemptions →
Frequently Asked Questions
Our calculator uses real effective rates from U.S. Census ACS 5-year estimates and county-published data. It is a reliable planning estimate. Your exact bill will depend on your parcel's specific assessed value, any applicable special-district levies, and exemptions you qualify for. Always verify the final amount with your county assessor or treasurer.
Market value is what your home would sell for today. Assessed value is what your local assessor places on it for tax purposes — in many states this is a fixed percentage (e.g., 80%) of market value, called the assessment ratio. Our calculator bypasses this complexity by using the effective rate, which already reflects the assessment ratio.
Yes. If your home's assessed value is higher than its fair market value, you can file an appeal with your county's Board of Equalization or Assessment Review Board. See our step-by-step appeal guide for timelines, evidence requirements, and hearing tips.
Our calculator gives a pre-exemption estimate based on full home value. If you qualify for a homestead, senior, veteran, or disability exemption, your actual bill will be lower. Enter your assessed value after applying exemptions for a more precise result.
Rates are updated annually between January and March after new Census ACS 5-year estimates are published. The data vintage is shown on every county page. For the very latest millage rates, check your county assessor's office directly.
