What to watch for
Bookkeeping in Wisconsin
Wisconsin owners near Chicago, Minneapolis or Madison often serve customers in more than one state. We keep each state's activity separate in the books.
A sales tax guide lists a 5% state rate, plus a 0.5% county tax in 70 of the 72 counties and 0.9% in Milwaukee County. Waukesha and Winnebago counties have no county tax. Filing frequency depends on how much tax you remit, and a return is required even when no tax was collected. We confirm your schedule on your own Department of Revenue account.
Official sources: Wisconsin Department of Revenue and the Wisconsin Department of Financial Institutions. Rules and rates change, so we confirm the current ones for your account.
What we handle for Wisconsin owners
- Sales tax returns on the schedule the Department of Revenue assigns, filed even in zero months
- The annual report to the Department of Financial Institutions
- Withholding and unemployment insurance reports for employees
- Local tax records, since county rates differ across the state
