How long does it take to form an LLC in Wisconsin?

Does Wisconsin have an LLC franchise tax?
No franchise tax for LLCs taxed as pass-through. Owners pay personal income tax (graduated up to 7.65%) on their share of LLC profits. LLCs that elect C-corp taxation are subject to Wisconsin's corporate franchise/income tax (7.9%).
When is the Wisconsin LLC annual report due?
By the end of the LLC's anniversary calendar quarter — i.e., the quarter that contains the LLC's formation date. For example, an LLC formed May 15 has its annual report due by June 30 every year. The fee is $25.
What's the Wisconsin LLC tax rate?
Wisconsin has graduated individual income tax topping at 7.65% — among the higher in the U.S. Sales tax is 5% statewide plus modest local add-ons (averaging 5.7% combined). LLCs taxed as pass-through don't owe state-level entity tax.
Can a non-resident form an LLC in Wisconsin?
Yes. Wisconsin has no residency requirement for LLC members or managers. You only need a Wisconsin-based registered agent. Out-of-state owners commonly use a commercial registered agent service.
Is Wisconsin a good state to form an LLC?
For Wisconsin residents and businesses tied to manufacturing (Milwaukee), dairy and agriculture, paper and packaging, or food/beverage (cheese, beer): yes. The $130 online filing + $25 annual + no franchise tax is competitive. The 7.65% top income tax is the trade-off — Wisconsin is more expensive than Indiana or Michigan for high-income LLC owners.
Do I need a business license for a Wisconsin LLC?
Wisconsin does not have a state-level general business license. Specific industries (real estate, contractors, food service, professional services, alcohol) require state licensing through the Department of Safety and Professional Services. Some cities (Milwaukee, Madison, Green Bay) require local registration.
