📐 Property Tax Formula

Taxable Value = Home Value − Homestead Exemption
Annual Tax = Taxable Value × Effective Rate %
Monthly Escrow = Annual Tax ÷ 12
Note: Actual bills depend on your county's assessed value ratio and mill rate. This calculator uses state average effective rates.

How Property Tax Works in the USA

Property tax is an annual tax levied by local governments (county, city, school district) on real estate. The tax is calculated using the property's assessed value multiplied by the local mill rate. Because assessed value often differs from market value, we use the effective rate — the tax as a direct percentage of market value — to give a consistent comparison across states.

Homestead Exemptions — Reduce Your Tax Bill

Most US states offer homestead exemptions that reduce the taxable value of your primary residence. Florida offers up to $50,000. Texas exempts $100,000 of school district taxes for homeowners 65+. California's Proposition 19 limits assessed value increases to 2% per year. Enter your exemption amount in the calculator above to see the impact.

States with No Property Tax?

Every US state levies some form of property tax, but rates vary enormously. Hawaii's effective rate of 0.28% is so low that despite median home values exceeding $700,000, annual tax bills average under $2,000. By contrast, New Jersey's 2.23% rate means a $400,000 home owner pays nearly $9,000 per year. The difference compounds significantly over 30-year ownership.

How to Appeal Your Property Tax Assessment

If you believe your property's assessed value is too high, you can appeal to your local assessor's office. Gather evidence: recent comparable sales in your neighborhood, a private appraisal, or photos documenting property condition issues. Most jurisdictions allow appeals within 30–90 days of receiving your assessment notice. Successful appeals can reduce your tax bill permanently.

How to Use the Property Tax Estimator

1

Enter your home's assessed value

Input your property's assessed value — found on your most recent tax bill or county assessor website. Assessed value is often 80–100% of market value, but varies significantly by jurisdiction.

2

Enter the effective tax rate

Use the effective tax rate for your county or municipality. The calculator includes a reference table for all US states. Local rates within a state can vary by 2–3× from the state average.

3

Add any exemptions

Homestead exemptions reduce your taxable assessed value. Common amounts: $25,000–$50,000 in Florida, $25,000 in Texas, variable amounts in most other states. Enter the exemption dollar amount, not percentage.

4

Review the annual and monthly figures

Property tax is an annual bill but is typically escrowed monthly by your mortgage lender. Divide the annual estimate by 12 to check against your escrow payment on your mortgage statement.

Frequently Asked Questions

Hawaii has the lowest effective property tax rate in the US at approximately 0.28% of assessed value. Alabama (0.40%), Colorado (0.51%), and Nevada (0.53%) also rank among the lowest. Despite Hawaii's low rate, high home values mean actual dollar amounts can still be substantial.
New Jersey has the highest effective property tax rate in the US at approximately 2.23%. Illinois (2.08%), Connecticut (1.92%), and New Hampshire (1.86%) also rank near the top. On a $400,000 home, New Jersey homeowners pay approximately $8,920 per year in property taxes.
Property Tax = Assessed Value × Mill Rate (tax rate). The assessed value is often a percentage of market value (the assessment ratio varies by county). The mill rate is set annually by local government. For example: $400,000 home × 1.0% effective rate = $4,000/year. This calculator uses average effective rates which already account for assessment ratios.
Property tax = assessed value × mill rate (or tax rate). Assessed value is typically 70–100% of market value depending on state. Mill rate is expressed per $1,000 of assessed value. Example: $350,000 assessed value × 1.2% effective rate = $4,200/year. Effective rates range from 0.28% (Hawaii) to 2.47% (New Jersey).
Yes. Most US counties allow annual appeals within a set window (typically 30–90 days after assessment notices are mailed). To appeal: gather comparable sales (similar homes that sold for less than your assessed value), attend the appeals board hearing, and present your evidence. Successful appeals typically reduce assessments by 10–25%. Many counties have an informal review before the formal appeal stage.
