Property Tax Calculator

Property tax = assessed value × local rate. U.S. effective rates range from about 0.3% (Hawaii) to over 2% (New Jersey, Illinois). Assessed value may lag or discount market value depending on the county's rules, and rates stack city, county, and school district levies.

Assessments are appealable — comparable-sale evidence wins reductions surprisingly often, and many jurisdictions offer homestead, senior, or veteran exemptions that must be claimed. A successful appeal compounds: it lowers every future year's bill too.
