    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.

    $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.

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.
