What this means

Property tax is set locally, by your county, city and school district. Each works out a value for your home (the assessed value) and charges a rate on it, so the bill on the same home can differ a lot between towns in the same state. Most homeowners pay it monthly with their mortgage, through an escrow account, or in one or two bills a year.

If you itemize deductions, property tax counts towards the deduction for state and local taxes (SALT), with your state income or sales tax: up to $40,400 in 2026 ($20,200 if married filing separately), less for incomes over $505,000.

Assumptions in this estimate
  • A state’s typical rate is what the median homeowner pays in property tax over what the median home is worth: $5,399 on $280,700 in Illinois. It’s the usual way to compare states.
  • Actual rates vary by county, city and school district, and your bill depends on your home’s assessed value, which can differ from what it would sell for. Your county assessor or tax collector has the rate and value for your home.
  • Many states lower the tax on a home you live in, with a homestead exemption, a cap on how fast its assessed value can rise, or relief for seniors, veterans or people with disabilities. Enter any exemption you get above.
