Property tax in Wisconsin is a local tax based on the assessed value of your home and land. The average effective rate — the tax actually paid as a share of market value — is about 1.42% statewide, though the real figure depends on your county, school district and any special levies. On the median Wisconsin home of roughly $290,000, that works out to about $4,118 a year. Most homeowners pay it monthly through an escrow account bundled into their mortgage payment.
Multiply your home's value by the effective rate. For example, a $290,000 home at 1.42% owes 290,000 × 1.42% = $4,118 per year. Enter your own home value above to get a personalised estimate, then confirm the exact local millage with your county assessor's office for budgeting.
