How this works in Wisconsin
Wisconsin's rule comes from the state's consumer protection code (ATCP 134). You have 21 days after the trigger date, which is usually the day the rental agreement ends, to return the deposit less permitted amounts, with a written itemized statement of anything you withheld.
Worked example for Wisconsin
Say the rental agreement ends on June 30, 2026. Return the deposit, less only amounts reasonably necessary for permitted items, with an itemized statement by July 21, 2026.
