In Wisconsin, how you file changes what you pay. Articles of Organization filed online cost $130, while the same form on paper costs $170. The annual report works the same way: $25 online. Its deadline is unusual, too. Instead of one statewide date, each LLC’s report is due by the end of the calendar quarter that holds its formation anniversary. Wisconsin has no separate annual franchise tax on LLCs, and DFI’s formation instructions include no newspaper publication step.

| Where to file | DFI Business Entity File Online |
Step 1Pick a name Wisconsin will accept
Under Wisconsin law, your LLC’s name must include “limited liability company,” “limited company,” “LLC” or “LC.” Changes in capitalization or punctuation are fine, and you may shorten “Limited” to “Ltd.” and “company” to “Co.” The name must also be distinguishable from other names already on DFI’s records. Words that show entity type, such as “LLC” or “Inc.,” don’t count when DFI compares names. A name also can’t suggest your company does regulated work (banking, for example) unless the law allows it.
To check what’s already taken, search DFI’s Corporate Registration Information System (CRIS). DFI warns that no name is guaranteed until your filing is accepted. If you aren’t ready to file yet, you can reserve a name for $15. The reservation holds it for 120 days and can be renewed.
Step 2Choose a registered agent
Every Wisconsin LLC must keep a registered agent and a registered office in the state. The agent receives lawsuits, official notices and annual report reminders for your company. It can be a Wisconsin resident (you, a member or someone you trust) or a business that offers agent service. The LLC can’t name itself as its own agent.
The registered office must be the agent’s business office at a real street address. A P.O. box, mailbox service or answering service alone does not qualify. The articles also ask for the agent’s email address, and Wisconsin law lets DFI send official notices to that email. Use an inbox someone actually checks.
Step 3File your Articles of Organization
Form 502 is short. It asks for:
- the LLC’s name
- a statement that the LLC is organized under chapter 183 of the Wisconsin Statutes
- the registered agent’s name and email address, and the registered office’s street address
- the principal office’s street and mailing addresses
- the name and full address of each organizer
- any optional extra provisions
At least one organizer signs it.
Online is the cheaper and usually faster route. You start from DFI’s File Online page, fill in the form and pay $130 by Visa, MasterCard, Discover or American Express. All online filings require a contact email, and that’s where DFI sends your confirmation. Documents filed online get only an emailed confirmation, not a paper copy.
On paper, the fee is $170, paid by check to the Department of Financial Institutions. Mail it to DFI at Box 93348, Milwaukee, WI 53293-0348. Express or priority mail goes to the department’s Madison office, at the address printed on the form.
Speed: DFI doesn’t publish a standard turnaround. For $100 more, it will act on your filing by close of business the next business day. The customer service counter in Madison also offers in-person service within four hours for $250 or within one hour for $500.
Step 4Keep up with the quarterly-timed annual report
Your first annual report is due in the calendar year after the year you formed the LLC. After that, one is due every year. Each report must be filed during the calendar quarter that contains your LLC’s anniversary date, by the end of that quarter. For example, an LLC formed in May has its report due by June 30, while one formed in November has until December 31. The fee is $25 online or $40 on paper. DFI emails a notice when the report is due.
If you miss it, the LLC becomes “delinquent.” You fix that by filing a current report and paying the back report fees. If several years pass without a report, DFI starts administrative dissolution. It tries to reach the LLC by mail, then publishes a notice, and dissolves the LLC 60 days after that notice if no report arrives. Reinstating an LLC after that means contacting DFI for forms, so it’s far easier to simply file on time.
Step 5Finish the rest of your setup
- Operating agreement. Wisconsin doesn’t ask you to file one, but a written agreement covering ownership, management and what happens if a member leaves is worth having, even for a single-member LLC.
- EIN. Get an Employer Identification Number free from the IRS. You’ll need one for a bank account and for hiring.
- State tax registration. If you’ll sell taxable goods or services, or withhold tax for employees, register with the Wisconsin Department of Revenue. The Business Tax Registration fee is $20 for new businesses and covers two years. A $10 renewal applies after that.
- Local licenses. Check with your city or county about any licenses or permits your type of business needs.

How Wisconsin compares
State filing fee to form an LLC, next to neighboring states. The national median is $100.
National median · Fees from each state's official sources; some states charge a different amount online or by mail. If you live and run your business in Wisconsin, forming your LLC in another state usually means also registering it here as a foreign LLC, so you pay both states' fees.
How Wisconsin taxes LLCs
Wisconsin doesn’t charge LLCs a separate yearly franchise or privilege fee just for existing. For state tax purposes, the Department of Revenue follows your federal classification. A single-member LLC is disregarded unless it chooses otherwise. A multi-member LLC is a partnership. An LLC that elects corporate treatment is taxed as a corporation. Wisconsin’s economic development surcharge no longer applies to LLCs taxed as partnerships. It can apply to LLCs taxed as corporations that have at least $4 million in gross receipts. LLCs taxed as partnerships with nonresident members generally have to withhold Wisconsin tax on those members’ shares.
File it yourself or use a formation service?
Wisconsin’s online form is simple enough that many owners file it themselves in one sitting. Filing yourself costs only the state fee. A formation service charges its own fee on top of that. In return, it may handle the paperwork, act as your registered agent or send annual report reminders. That can be worth paying for if you want a professional agent address or don’t want to track deadlines yourself. Either way, the state filing is the same.
Frequently asked questions
When is my first Wisconsin annual report due?

Is filing online really cheaper?
Yes. Online Articles of Organization cost $130 versus $170 on paper. Online annual reports cost $25 versus $40.
Can I be my own registered agent?
Yes, if you live in Wisconsin and have a business office at a street address in the state. The LLC itself can’t serve as its own agent.
