Property Tax Calculator

Property tax is an annual tax levied by local governments based on the assessed value of real estate. The amount you owe depends on two main factors: your property assessment (the value assigned by a local assessor) and the local tax rate, often expressed as a millage rate (dollars per thousand of assessed value). Some jurisdictions offer homestead exemptions that reduce the taxable portion of your home value, while others apply different rates for residential versus commercial properties. This calculator lets you enter your property assessed value, the local tax rate, and any applicable exemptions to instantly compute your annual property tax bill. It also provides a monthly breakdown to help with budgeting, and can compare tax obligations across multiple properties or scenarios. All calculations use standard formulas and run entirely in your browser — your property and financial data stays private on your device, never sent to any server.

Property tax computation involves multiplying the taxable assessed value by the applicable tax rate. The assessed value may differ from market value — many jurisdictions assess at a percentage of fair market value (for example, 80% in some counties). The tax rate itself is set by combining levies from multiple local authorities: county government, city or town, school district, and special districts (fire, water, library). When expressed as a millage rate, one mill equals one dollar per thousand dollars of assessed value, so a rate of 25 mills on a property assessed at $200,000 produces a $5,000 annual tax bill. Our calculator handles these conversions automatically. Enter your values and the tool computes your total tax, effective rate as a percentage, and monthly payment amount. The calculation is pure JavaScript arithmetic — no external APIs or server calls are made, ensuring your property valuation and location data remain completely private on your device.
