LLC Formation 2026-03-20

Step 1: Choose Your LLC Name

Your LLC name must be distinguishable from all other registered Wisconsin business entities and must include "Limited Liability Company," "LLC," or "L.L.C." Search the Wisconsin DFI database at apps.dfi.wi.gov to confirm your name is available before filing. The search is free.

Pro tip: check that your desired name is also available as a domain name and on Google before committing. A Milwaukee business competing locally needs a web presence — and a matching domain matters.

Step 2: Choose a Registered Agent

Every Wisconsin LLC must designate a registered agent with a physical Milwaukee or Wisconsin address. As a Milwaukee business owner, you have two practical options:

• Serve as your own RA: Your home or business address becomes public on the Wisconsin DFI database. Anyone can look up your LLC and see your address.
• Use a professional RA service: A professional address (like 790 N. Milwaukee Street, Suite 300) appears on DFI records instead of your home. Your personal address stays private.

For Milwaukee business owners operating from home or a residential address, a professional RA service is almost always worth the cost. The Wi Filings address is a commercial office building three blocks from City Hall — it is exactly the kind of address that adds credibility to a Milwaukee business.

Step 3: File Your Articles of Organization

File online at apps.dfi.wi.gov. The state filing fee is $130 for online submissions. You will need your business name, registered agent information, principal office address, organizer name and address, and management structure (member-managed or manager-managed).

Processing typically takes 1–5 business days. You can also use Wi Filings to handle the entire filing for $79 service fee — we prepare the documents, file with the DFI, and confirm completion.

Step 4: Get Your EIN

Apply for an Employer Identification Number at IRS.gov immediately after your LLC is approved. It is free and instant. You will need your EIN to open a Milwaukee business bank account, hire employees, and file Wisconsin business taxes.

Step 5: Open a Milwaukee Business Bank Account

Open a business checking account in your LLC's name using your EIN and Articles of Organization. Milwaukee has strong local banking options including Associated Bank (headquartered in Green Bay with strong Milwaukee presence), BMO Harris (preferred SBA lender), and Educators Credit Union (member-owned, competitive rates).

For Milwaukee startups with no revenue history, Mercury Bank (online, free) is an excellent starting point with zero fees and no minimum balance requirements.

Step 6: Milwaukee Business License Requirements

Depending on your business type, you may need a Milwaukee City Business License. Most service-based businesses operating from a home office do not require a city license, but retail locations, food service, childcare, and certain professional services do. Check with the City of Milwaukee's Office of Neighborhood Services at milwaukee.gov/ons for current licensing requirements.

A professional registered agent address at 790 N. Milwaukee Street can be used as your principal office address — which may simplify certain licensing applications that require a business address.

Step 7: File Your Annual Report (Every Year)

Wisconsin requires every LLC to file an annual report with the DFI each year. The deadline varies by your LLC's anniversary date. Missing it triggers a $25 late fee and eventually administrative dissolution. Wi Filings auto-files your annual report as part of the registered agent service — so you never have to track the deadline yourself.
