A landlord must return the deposit, or send an itemized list of deductions, within 21 days of the end of the tenancy. If you move out early, the 21 days run from the lease end date or the date a new tenant moves in, whichever comes first. A landlord may deduct for unpaid rent, damage beyond normal wear and tear caused by you or your guests, and certain unpaid utilities, and must itemize any amount withheld in writing. The state's tenant guide doesn't list a dollar cap, but it says advance payments above one month's rent must be treated as a security deposit. These are state rules, so they apply in Madison and elsewhere in Wisconsin. Keep your move-out records.
