How to start an LLC in Wisconsin: step by step
Here is exactly what forming a Wisconsin LLC involves, whether you file it yourself or let Incofile handle the paperwork.
Choose and check your LLC name
Pick a name that includes “LLC” or “Limited Liability Company” and is distinguishable from existing Wisconsin businesses. Check it with our free business name search.
Appoint a registered agent
Name a registered agent with a physical street address in Wisconsin (not a PO box) who can accept legal papers during business hours. If you live outside Wisconsin or want privacy, Incofile can act as your agent.
File the Articles of Organization
File Form 502 online with the Department of Financial Institutions and pay $130 ($170 on paper). Expedited service ($100) is acted on by the close of the next business day.
Create an operating agreement
Wisconsin does not require you to file an operating agreement, but it records who owns the LLC, how profits are shared and how decisions are made. Banks commonly ask for it, and it helps protect your limited liability.
Get an EIN
Apply to the IRS for your Employer Identification Number (EIN). You need it to open a business bank account, hire staff and file federal taxes. The IRS issues it free; non-US owners without an SSN apply by phone, fax or mail, and our Gold package handles it for you.
Register for taxes and local licences
Complete the Business Tax Registration with the Wisconsin Department of Revenue ($20 for two years) for a seller’s permit and withholding if needed. There is no general state business licence; check your city for local licences.
File your annual report each year
File the $25 annual report online during the calendar quarter that contains your anniversary (by 31 March, 30 June, 30 September or 31 December), starting the year after formation. Persistent non-filing leads to administrative dissolution.
What you need to form an LLC in Wisconsin
- A business name that is available and meets Wisconsin's naming rules (it must include “LLC” or “Limited Liability Company”).
- A registered agent with a physical address in Wisconsin — Incofile can be your agent.
- Articles of Organization filed with the Wisconsin state office — we prepare and submit these for you.
- An operating agreement and EIN to open a business bank account (included in our Gold and Platinum packages).
- Ongoing compliance — Wisconsin's reports, taxes and registered agent rules (see below). We track the deadlines and remind you.
Operating agreement
An operating agreement sets out who owns the LLC, how profits are split, how decisions are made and what happens if a member leaves. Wisconsin does not ask you to file it with the state, but banks usually want to see it, and without one the state's default rules apply. Incofile includes a customised operating agreement in the Gold and Platinum packages.
EIN (Employer Identification Number)
Your EIN is the federal tax ID for your LLC. You need it to open a business bank account, hire staff and file taxes. The IRS issues it free — online in minutes if you have a Social Security number, or by fax or mail (one to eight weeks) if you don't. Our Gold and Platinum packages include it, and it is also available as a separate service.
This is general information, not legal advice. If you're unsure which structure is right, compare LLC vs S-Corp vs C-Corp.
Wisconsin LLC naming rules
The name must contain “Limited Liability Company” or an abbreviation such as “LLC” or “L.L.C.” and must be distinguishable from every other entity on the Wisconsin register. Check availability with our free business name search.
Keeping your Wisconsin LLC compliant
Annual report
Wisconsin LLCs file an annual report during the calendar quarter containing their organisation anniversary — by 31 March, 30 June, 30 September or 31 December — starting the year after formation. It costs $25 online ($40 on paper). There is no late fee, but an LLC that keeps missing reports is administratively dissolved.
Registered agent
Your agent must be an individual or entity resident in Wisconsin at an actual physical street address, not solely a PO box or mailbox service. Incofile can act as your Wisconsin registered agent.
Taxes
Owners pay Wisconsin income tax on their share of profit at graduated rates from 3.5% to 7.65%. There is no franchise or minimum tax on an LLC taxed as a partnership or disregarded entity.
Licences
There is no general state business licence. If you sell taxable goods or have employees, complete the Business Tax Registration with the Department of Revenue ($20, covering two years) to get your seller’s permit.
Incofile clients get every Wisconsin deadline tracked in their dashboard with email reminders — see registered agent service.
