How to Start an LLC in Wisconsin (2026)

Full transcript

0:00 The short answer

Dan To start an LLC in Wisconsin, you file Articles of Organization, Form 502, with the Wisconsin Department of Financial Institutions. The fee is $130 online, or $170 on paper.

Maya So online saves $40?

Dan It does, and online filings are usually accepted on receipt.

Maya This is The Business Formation Podcast. Today, Wisconsin for 2026: six steps, every fee, and the three best ways to have it filed for you. Where do we begin?

0:33 Step 1: Choose a name

Dan Start with the name. It needs the words limited liability company, limited company, or the abbreviation LLC or LC.

Maya Anything else?

Dan Check that nobody has filed something too close to it. The DFI keeps the business entity records you search.

Maya And if I'm not ready to file?

Dan A name reservation is $15 and holds the name for 120 days.

0:59 Step 2: Pick a registered agent

Maya Do I need an agent in Wisconsin?

Dan Yes. Every Wisconsin LLC names a registered agent, and that agent must be reachable at a physical Wisconsin street address, with an email address on file.

Maya Can I use a P.O. box?

Dan Not on its own, and a mailbox service doesn't count either.

Maya I'm Maya, by the way, here with Dan.

Dan Good to be here, Maya. One more rule people miss: the LLC can't be its own agent.

Maya So who can serve?

Dan A Wisconsin resident, or an authorized business. Changing the agent later is $10 online.

1:36 Step 3: File Form 502

Maya Now the filing itself.

Dan Form 502, the Articles of Organization. File online with the DFI for $130, or mail the paper form for $170.

Maya How fast is online?

Dan Usually accepted on receipt, so you can have an active LLC the same day.

Maya Same day, at the standard price?

Dan Often, yes. If you want it guaranteed by the next day, expedited processing is $100 extra.

2:06 Step 4: Write an operating agreement

Maya Is the operating agreement filed with the state?

Dan No. It stays with your records, and there's no state fee for it.

Maya Do I even need one?

Dan Wisconsin treats an LLC as member-managed unless a written operating agreement says otherwise.

Maya So if I want a manager running things?

Dan Then put it in writing. Cover who owns what, how profits are split, who decides, and what happens when a member leaves.

2:32 Step 5: Get a free EIN

Maya What about the federal side?

Dan Apply for your EIN with the IRS at IRS.gov. It's free, and if it's approved online, the number is issued right away.

Maya Is there an ownership report?

Dan Not for U.S. companies. FinCEN no longer requires one.

2:50 Step 6: File the annual report

Maya And what does Wisconsin want each year?

Dan An annual report, starting the year after you form. It's $25 online.

Maya When is it due?

Dan By the end of the calendar quarter of your formation anniversary. Form in May, and your report is due by the end of June of the following year.

Maya What if I miss it?

Dan The LLC becomes delinquent. A year overdue can lead to administrative dissolution, after a 60-day notice.

3:16 What it costs

Maya Give me the do-it-yourself total.

Dan $130 to form the LLC online. The EIN is free. Then $25 a year for the annual report.

Maya So the first year is $130?

Dan Yes, and the first report isn't due until the year after.

Maya And the extras?

Dan A name reservation is $15, an agent change is $10, and next-day expedited processing is $100.

3:45 Rush options

Maya Let's talk about speed. Is there anything faster than online?

Dan If you're filing in person, there's a 4-hour expedite for $250. Online, next-day expedite is $100.

Maya That's a lot more than the filing fee.

Dan It is, which is why most owners don't bother. Online filings are usually accepted on receipt anyway.

Maya So when would anyone pay?

Dan When a bank, a landlord, or a contract has a hard date, and you can't risk a delay.

4:12 The agent rules in detail

Maya Let me go back to the agent. Why does the address rule matter?

Dan Because legal papers are delivered there. The agent has to be someone who's actually available at a Wisconsin street address during business hours.

Maya So I can't list a friend in another state?

Dan Not unless they're a Wisconsin resident with a real street address.

Maya And if I move or the agent quits?

Dan You file a statement of change. Online, that's $10.

Maya What about me serving as my own agent?

Dan You can, if you live in Wisconsin and you're home during business hours. Many owners prefer a service so the papers never land on their doorstep.

4:50 Paper or online

Maya Is there any reason to file on paper?

Dan Only if you can't file online. Paper is $170, which is $40 more than the $130 online fee.

Maya And is it slower?

Dan Usually, yes. Online filings are typically accepted on receipt, while a paper form has to travel and be processed.

Maya So online is cheaper and faster.

Dan For nearly everyone, unless you specifically need to file on paper.

5:19 Planning your annual report

Maya Back to the report. How do I remember the date?

Dan Tie it to your anniversary quarter. If you form in the first quarter, the report is due by the end of March the following year.

Maya And the fee?

Dan $25 online. It's small, but a missed one makes the LLC delinquent.

Maya So set a reminder.

Dan Set it for the start of the quarter, not the last week. A year overdue and the state can begin the dissolution process.

5:48 Your first-year checklist

Maya Order of operations?

Dan Search the name. Choose your agent. File Form 502 online for $130.

Maya Then?

Dan Write the operating agreement, get your EIN, and mark your anniversary quarter for the $25 annual report.

6:04 The 3 best ways to file in Wisconsin

Maya What if I'd rather have someone else handle it?

Dan Here are the three best ways to file in Wisconsin. Number one, our pick, is Mainstay Filing, $199 a year plus the state fee. With the $130 state fee, checkout comes to $329.

Maya What's included?

Dan Your Form 502 filed, your EIN application, and your registered agent every year. It renews at the same $199.

Maya And the annual report?

Dan Mainstay files it for you in your anniversary quarter. You pay only the $25 state fee.

Maya Number two?

Dan WI Registered Agent.org. It prepares and files your Articles for $199 plus the state fee, also $329 at checkout. The first year of agent service is free, then $99 a year.

Maya And three?

Dan Wisconsin Registered Agent.co. Same offer: $199 plus the state fee, first year of agent service free, then $99 a year.

Maya How do I choose?

Dan If you'll file the annual report yourself, numbers two and three cost less from year two, at $99 a year for the agent alone. The $25 state fee is the same either way.

7:24 Three years of service fees

Maya Give me the three-year view.

Dan Mainstay is $199 a year, so $597. Number two or three is $199 in year one, then $99 for each of the next two years, so $397.

Maya A $200 gap.

Dan Yes. With Mainstay, that gap pays for your annual report to be filed for you.

7:50 Recap

Maya Can you recap?

Dan Choose a name ending in LLC, pick a Wisconsin registered agent with a street address, file Form 502 online for $130, write an operating agreement, get your free EIN, and file your $25 annual report by the end of your anniversary quarter.
