Best LLC Formation Services in Wisconsin

Wisconsin has no franchise tax, which puts it ahead of neighboring Illinois, where LLCs pay an annual franchise tax that was $75 until recently. Your ongoing state costs here are limited to a $25 annual report.

The state does charge state income tax, with rates ranging from 3.54% to 7.65%. That is a real cost compared to forming in Wyoming or South Dakota, but Wisconsin's pass-through taxation and lower filing fees often make it cheaper overall than running a foreign LLC registration in a no-tax state.

Wisconsin lets you reserve your LLC name for 120 days for just $15. That is twice as long as most states offer, which gives you extra runway if you need to line up funding or finalize an operating agreement before filing.

If you miss your annual report deadline, Wisconsin does not charge a late fee. Instead, the state can administratively dissolve your LLC. Reinstatement costs $100 plus all delinquent annual report fees, so staying current is far cheaper than catching up.

1. Get your EIN from the IRS (free, immediate online). You need this before opening a business bank account or hiring employees. Apply directly at IRS.gov.
2. Appoint and maintain a registered agent in Wisconsin. Your agent must be a Wisconsin resident or a business entity authorized to operate in the state, with a physical street address available during normal business hours.
3. File your Annual Report by the end of the calendar quarter containing your formation anniversary. The fee is $25, and you file with the Department of Financial Institutions. Missing it risks administrative dissolution.
4. File a BOI (Beneficial Ownership Information) report with FinCEN. Most new LLCs formed in 2024 or later must file within 90 days of formation. This is a federal requirement, not state, but it applies to your Wisconsin LLC.
5. Check for local and industry-specific licenses. Wisconsin has no general state business license, but many cities and counties require their own permits. Milwaukee, Madison, and other municipalities each have separate licensing requirements.

• Mail vs. Online Filing Gap - Filing by mail costs $170, which is $40 more than the $130 online fee. Always file online through the Department of Financial Institutions.
• Reinstatement After Dissolution - If your LLC is administratively dissolved for missing annual reports, reinstatement costs $100 plus every delinquent $25 annual report fee you owe.
• Expedited Filing Fee - Wisconsin charges $25 for expedited processing, which gets you approval by close of business the next business day. Standard online filing is already immediate, so this is rarely necessary.
