The 7-Step Wisconsin LLC Formation Process
Every Wisconsin LLC follows the same core process. Here is exactly what happens, in order, and what Gullia Filing handles on your behalf.
Choose a Wisconsin LLC name
Pick a name that includes "LLC", "L.L.C.", or "Limited Liability Company" and is distinguishable from existing Wisconsin entities. Our free name check tool verifies availability against the Wisconsin Secretary of State database in seconds.
Appoint a Wisconsin registered agent
Wisconsin requires a registered agent with a physical street address in the state to receive legal and tax notices. Gullia Filing provides this service in every package, protecting your privacy and ensuring you never miss a critical filing.
File the Articles of Organization
Submit formation paperwork to the Wisconsin Secretary of State with a $130 filing fee. Expedited processing is available for $25 additional. We handle the filing electronically and forward your certified copy within 5-7 business days.
Obtain your EIN (Federal Tax ID)
Apply to the IRS for an Employer Identification Number, required to open a US business bank account, hire employees, and file federal taxes. Included free in every Gullia Filing package.
Draft an operating agreement
An operating agreement establishes member rights, profit distributions, management structure, and dispute resolution. Even single-member LLCs benefit from having one on file for bank account opening and to reinforce the corporate veil. We provide a state-compliant, attorney-reviewed template in every package.
Register for Wisconsin taxes and licenses
Register with the Wisconsin Department of Revenue for state tax IDs, sales tax permits if applicable, and any industry-specific licenses. Our compliance calendar tracks every deadline automatically.
Open a US business bank account
With your EIN, Articles of Organization, and operating agreement, you can open a US business bank account. We provide bank-ready document packages and can introduce you to fintech partners that accept remote onboarding.
