Tax burden on Wisconsin rentals

Property tax

1.61%

effective rate on median home value

At 1.61% effective, this is one of the highest property tax burdens in the country (rank 44 of 51). Every underwrite needs to account for the full carrying cost. Even a strong rent-to-price ratio can go negative once property tax is properly modeled.

State income tax

7.65%

top marginal rate

A top marginal rate of 7.65% is high nationally. Rental portfolio income at scale takes a significant state hit on top of federal, so serious operators lean hard on depreciation, cost segregation and 1031 deferral. Long-term hold economics reward staying under the top bracket where possible.

Security deposit rule

No statutory cap on security deposits. Landlords set the deposit at whatever the market accepts, typically one to two months' rent, sometimes more for higher-risk applicants or pets. Local ordinances may still apply.

Deposit rules change; verify current statute before drafting a lease.
