Surplus-Lines Tax and Stamping Office

Reported tax rate: 3% of premium The NAIC's state chart lists a 3% of premium charge for surplus-lines coverage for Wisconsin (the chart's state entries were reviewed in October 2025). Your broker may collect the applicable amount with the premium. Surplus-lines insurers are not licensed in the state and generally are outside state guaranty-association protection; ask your broker to explain the insurer's financial protections and any diligent-search requirement that applies to your placement. ^4,5
