  1. Wisconsin Department of Revenue - Seller's Permit

    Required of every individual, partnership, corporation or other organization with a Wisconsin sales location making retail sales of taxable products or taxable services, with limited exceptions for wholesalers, manufacturers and certain marketplace sellers. The permit is issued through Business Tax Registration, which also covers withholding and use tax accounts. Rates: 5% state; seventy counties add 0.5%; Milwaukee County is 0.9% and the City of Milwaukee adds 2%, both effective January 1, 2024, so the rate inside Milwaukee is 7.9% - the only Wisconsin city with a municipal sales tax.

    Official government source

    $20 one-time Business Tax Registration fee, then $10 to renew every two years - it is not free. The $20 is the same regardless of how many locations need a seller's permit. DOR can additionally require a security deposit of up to $15,000 in some cases, returned after 24 consecutive months of compliance.Register online through My Tax Account. DOR does not publish a guaranteed processing time - contact [email protected] or 608-266-2776 to check status.

  2. Wisconsin DNR - Used Oil and Hazardous Waste

    Wisconsin auto repair shops must comply with DNR used oil and hazardous waste management standards (Wis. Admin. Code ch. NR 679). Used oil, antifreeze and other automotive fluids must be stored in appropriate containers and recycled or disposed of properly; landfilling used oil and filters is banned. This is an ongoing compliance obligation, not a one-time state registration or permit for typical small-quantity generators.

    Official government source

    No DNR registration or permit fee for typical small-quantity generators; collection, recycling and disposal are priced by private used-oil haulers and recyclers.Ongoing compliance - no separate registration or permit application for typical shops.

  1. City of Madison - No General Business License

    The City of Madison does not have a general/generic business license. Per the city's own guidance: "The City of Madison does not have a generic business license. Most licenses issued by the Clerk's Office are for things that need to be inspected" (e.g. restaurants, pools, hotels). There is no general or blanket business license and no annual renewal or display requirement for most business types. The Clerk's Office licenses only specific regulated activities - alcohol, tobacco and vaping, adult entertainment, secondhand dealers, transportation and tattooing among them. A Certificate of Occupancy from the Building Inspection Division is still required for a commercial space.
