Register online through My Tax Account before the first sale. The seller’s permit must be displayed and is the document the landlord and the municipality ask for; the renewed Business Tax Registration certificate carries the permit’s new expiration date. The same registration opens the withholding account once you hire, and county and Milwaukee local sales taxes go on the same return.
