Formation

Darius F. Sanders · Founder, Wi Filings · Published 2026-05-08

Green Bay is a focused small-business market — Packers tourism, paper and packaging, healthcare, and growing trades work all support steady LLC formation in Brown County. The state-level filing process is the same as anywhere in Wisconsin, but Green Bay’s city licensing, event-vendor contracts, and Brown County health rules add a layer most owners don’t expect.

Step 1 — Decide your structure

LLC is the right answer for most Green Bay small businesses. Wisconsin DFI saw 19,705 new LLCs in Q1 2026 — about 92% of all new entities. Liability protection plus simple pass-through taxes is the standard answer for solo and small-team operators.

Step 2 — Name search

Green Bay names often include “Bay,” “Packer,” “Titletown,” “Fox River,” or geographic descriptors. Some Packers-related terms are trademarked by the Green Bay Packers organization; using them in a business name can trigger a federal trademark claim regardless of DFI approval. Use our free live DFI name checker to verify availability, then search USPTO for federal trademark conflicts before you commit.

Step 3 — Wisconsin registered agent

You need a Wisconsin registered agent with a Wisconsin street address available during business hours. Wi Filings provides a Milwaukee registered agent address for your Wisconsin DFI public records. For DOR registration, banking, and local Green Bay or Brown County licensing forms, use the address that accurately fits the specific form field.

Step 4 — File the Articles of Organization

State filing fee is $130 online. Wi Filings files for $209 all-in, including registered agent year one. Processing is typically one to three business days.

Step 5 — Get your EIN

Required for most Green Bay LLCs opening a business bank account. The IRS charges nothing. Wi Filings files for $49.

Step 6 — Register with the Wisconsin DOR

Set up your My Tax Account at revenue.wi.gov. Brown County’s combined sales tax rate includes the state rate plus the Brown County 0.5% — confirm the current rate during DOR setup.

Step 7 — Green Bay-specific licensing details

Green Bay’s local licensing is especially important for mobile, event, food, contractor, and right-of-way businesses. The city does not treat every LLC the same. A home-based consultant may only need state-level filings and tax registration, while a food truck, direct seller, concrete sidewalk contractor, sprinkler installer, tree trimmer, or alcohol-related business may need a city license before operating.

For mobile food vendors, the City of Green Bay requires a license from the City Clerk to conduct business in the city. The city’s application asks for:

• Brown County Health Department certificate or State of Wisconsin health certificate
• Wisconsin seller’s permit
• Certificate of insurance
• Vehicle registration
• Hold harmless agreement
• Valid government ID

The city’s mobile food vendor license expires annually on December 31. The application instructions also list insurance requirements, including general liability and auto liability coverage.

Direct sellers and solicitors are treated differently in Green Bay. A direct seller permit is assigned to a location; a solicitor license is person-specific and applies to someone moving from place to place. Green Bay specifically notes that applicants looking to sell around Lambeau Field may need a solicitor permit rather than a direct seller permit because they are expected to keep moving instead of setting up a fixed stand.

Brown County food business layer

If your Green Bay LLC sells food, Brown County Public Health may be part of your setup. Brown County’s mobile food operational plan asks for the service base address, mobile overnight storage address, planned vending locations, available restrooms, menu, food sources, food preparation activities, water tanks, wastewater tanks, equipment layout, and service base sharing agreement if you use a rented commercial kitchen.

That means a Green Bay food truck should not wait until the week before launch. Build the LLC first, get the EIN, apply for the Wisconsin seller’s permit, line up the service base or commissary, then work through Brown County and City of Green Bay licensing.

Not every Green Bay LLC needs a city license

Many consultants, online businesses, freelancers, landlords, and professional-service LLCs only need the Wisconsin LLC filing, registered agent, EIN, DOR registration (if applicable), and annual report tracking. The point is to check before you open, not to assume every business needs every permit.
