Dissolve a Wisconsin LLC or corporation

File with the Wisconsin Department of Financial Institutions. Ask the Wisconsin Department of Revenue about tax clearance first.

The catch

Only articles of dissolution filed with DFI end the entity. Your Revenue accounts close on their own track, with final returns due within 30 days.
