Wisconsin Late Fee Laws

Last reviewed: July 10, 2026

Maximum late fee
No statutory cap
Grace period
None required
Statute
Wis. Stat. ch. 704; Wis. Admin. Code ATCP 134

Wisconsin sets no statutory dollar cap on residential late fees — Wis. Stat. ch. 704; Wis. Admin. Code ATCP 134 governs the landlord–tenant relationship, and courts still expect a late fee to be a reasonable estimate of actual damages rather than a penalty.

Wisconsin's statute doesn't impose a waiting period, so the lease controls when a late fee may be charged. Charging from day one is legal here only if the lease says so explicitly.

Wisconsin sets no cap, but the ATCP 134 consumer-protection rules require the fee to be disclosed and prohibit charging a late fee on an unpaid late fee. Violations of ATCP 134 carry double-damages exposure, so lease drafting matters more here than the absence of a cap suggests.
