Starting an LLC in Wisconsin costs $130 in state fees when you file online ($170 by mail) through the Wisconsin Department of Financial Institutions (DFI) — Wisconsin uses the DFI, not a Secretary of State, for business filings. Online filings are usually accepted on receipt, often within 1 business day. The six steps are: choose a compliant LLC name, appoint a Wisconsin registered agent, file Articles of Organization (Form 502), draft an operating agreement, get a federal EIN from the IRS, and register for Wisconsin tax accounts if your business needs them. No US citizenship, residency, or Social Security number is required to own a Wisconsin LLC.

How Much Does It Cost to Start an LLC in Wisconsin?
Wisconsin is one of the most affordable states to form and maintain an LLC — cheap filing, no franchise tax, and a $25 annual report. Here is the full breakdown (fee schedule current as of October 2026; the DFI can change fees, so double-check before filing):
| Item | Cost |
|---|---|
| Articles of Organization (online) | $130 (+ $1 portal fee) |
| Articles of Organization (by mail) | $170 |
| Name reservation (optional, 120 days) | $15 |
| Registered agent (if using a service) | Varies — standalone registered agent service is $200/year at Registered Agents Inc; included free for year one with their $100 + state fee formation bundle |
| Annual report (every year, online) | $25 ($40 by mail) |
| Certificate of Status / Good Standing | $10 |
| Business Tax Registration (seller’s permit) | $20 (valid 2 years) |
| Franchise tax | None — Wisconsin does not impose a franchise tax on LLCs |
That $130 online filing and $25 annual report is what most guides get right — but many omit the $1 portal fee on online filings and the fact that paper filing costs $40 more. Wisconsin LLC filing fees are non-refundable even if your filing is rejected, so get the name and addresses right before you pay.
Why Registered Agents Inc for a Wisconsin LLC? They charge a flat $100 + state fee to form your LLC, which includes the state filing itself, a domain name, a website, and one year of free registered agent service (check current pricing — add-on website, phone, and email tools are $5/month each). Because Wisconsin’s $130 state fee is so low, the bundle keeps your entire first-year setup cost predictable. Start your Wisconsin LLC here →
Step 1: Choose Your LLC Name
Wisconsin naming rules (under Chapter 183 of the Wisconsin Statutes) require:
- The name must include a recognized LLC designator: “Limited Liability Company,” “Limited Company,” “LLC,” “L.C.,” or “LC.”
- It must be distinguishable from every existing entity on file with the DFI. Search the free CRIS name database on the DFI’s website before you commit — treat every result as tentative until the DFI stamps your filing FILED.
- Avoid restricted words like “Bank,” “Insurance,” or “University” unless you hold the required licenses or approvals.
If you are not ready to file yet, you can reserve your name with Form 1 for $15, which holds it for 120 days (current as of October 2026). Double-check spelling before filing — amending your LLC name later costs extra.
Step 2: Appoint a Wisconsin Registered Agent
Every Wisconsin LLC must continuously maintain a registered agent with a physical street address in Wisconsin — P.O. boxes do not qualify. The registered agent receives lawsuits, tax notices, and official DFI correspondence on your LLC’s behalf and must be available in person during normal business hours.
Your options:
- Yourself — only if you live in Wisconsin and are available at that address during business hours. Not an option for foreign founders.
- A trusted person in Wisconsin — but their address becomes public record on the DFI’s searchable database.
- A professional registered agent service — the standard choice for non-resident and non-US founders. The agent’s name, Wisconsin street address, and email go directly on your Articles of Organization, so a service also keeps your personal address off the public record.
Read more about whether you need a registered agent before deciding. If you change agents later, file a Change of Registered Agent form with the DFI to stay in good standing.
Step 3: File the Articles of Organization
This is the filing that legally creates your LLC. Wisconsin’s Articles of Organization is Form 502, filed with the DFI’s Division of Corporate and Consumer Services under Chapter 183. You have two filing methods (fees current as of October 2026):
Online (recommended): File through the DFI’s One Stop Business Portal. Create a free account, select “File Articles of Organization,” and complete the form. You will need: your LLC name, your registered agent’s name and Wisconsin street address, your principal office address (this can be outside Wisconsin, including abroad), your management structure (member-managed or manager-managed), and the organizer’s details. The fee is $130 + a $1 portal fee, payable by credit card. Online filings are usually accepted on receipt — often within 1 business day — with immediate confirmation.
By mail: Download Form 502 from the DFI website, complete it, and mail it with a check for $170 payable to the Department of Financial Institutions. Mail filings typically take 5–10 business days or longer.
If you need it faster, the DFI offers expedited service: +$100 for next business day, +$250 for same-day (within 4 hours), or +$500 for same-hour processing (current as of October 2026).
Once accepted, the DFI stamps your Articles FILED — that stamp date is your LLC’s official formation date, and it determines when your annual report is due each year (see below).
Step 4: Create an Operating Agreement
Wisconsin does not legally require LLCs to have an operating agreement — but you should create one anyway, especially as a non-US founder. The operating agreement is the internal document that spells out ownership percentages, how profits and losses are divided, how decisions get made, what happens if a member leaves, and how the LLC can be dissolved.
Why it matters more than the state requires:
- Banks ask for it. Most US banks want to see an operating agreement when you open a business account, and foreign-owned LLCs face extra scrutiny.
- It proves you are a real business. Payment processors (Stripe, PayPal), marketplaces, and even some vendors request it during verification.
- Single-member LLCs need it too. It reinforces the separation between you and the LLC, which is the entire point of limited liability.
Draft one yourself from a reputable template or have a business attorney review it. Keep the signed copy with your LLC records — it does not get filed with the DFI.
Step 5: Get Your Federal EIN
Your Employer Identification Number (EIN) is the LLC’s federal tax ID, issued free by the IRS. You need it to open a US business bank account, hire employees, and file federal taxes. No Social Security number or ITIN is required to get an EIN as a foreign founder — if you have no SSN, you file IRS Form SS-4 and submit it by fax to the IRS (the IRS does not currently accept online EIN applications from applicants without an SSN/ITIN). Processing by fax typically takes about a week, though timing varies — allow extra lead time.
Key details:
- The EIN application is always free. Never pay a third party for the number itself (formation services charge for handling the paperwork, which is legitimate, but the EIN costs nothing from the IRS).
- Apply only after your Articles of Organization are accepted — the IRS wants your exact legal name and formation date.
- If you are a foreign-owned single-member LLC, you will also need to file Form 5472 with a pro forma Form 1120 each year, reporting transactions between you and the LLC. This is an IRS information return, separate from income tax.

Step 6: Handle Wisconsin Tax Registrations
Wisconsin does not issue one blanket state business license, and LLCs are generally pass-through entities for income tax — the LLC itself does not pay state income tax; members report the income. But depending on what your business does, you may need state tax registrations:
- Seller’s permit (Business Tax Registration): If you sell tangible goods or taxable services to Wisconsin customers — including online sales — you must register for a seller’s permit with the Wisconsin Department of Revenue (DOR) and collect sales tax. Register online through the DOR’s My Tax Account (MTA) system or file Form BTR-101. The registration fee is $20, valid for two years ($10 to renew), current as of October 2026. Wisconsin has an “occasional sales” exemption: you generally do not need a permit if your taxable sales are under $2,000 in a calendar year. Wisconsin’s state sales tax rate is 5%, with county and local taxes added on top — check the combined rate for your customer’s location.
If you hire employees, also register for a Wisconsin withholding tax account and with the Department of Workforce Development for unemployment insurance taxes.
Wisconsin LLC Annual Report
Every Wisconsin LLC must file an annual report with the DFI each year — an informational filing confirming your LLC’s name, registered agent, principal office address, and members/managers. Even if nothing changed, you still file.
Deadline: Wisconsin’s rule is unusual — your report is due by the end of the calendar quarter in which your LLC was formed, every year:
| Formed between | Annual report due by |
|---|---|
| January 1 – March 31 | March 31 |
| April 1 – June 30 | June 30 |
| July 1 – September 30 | September 30 |
| October 1 – December 31 | December 31 |
Form your LLC on November 15, 2026, and your first annual report is due by December 31, 2027 — not immediately. Fee: $25 online / $40 by mail (current as of October 2026). There is no published late fee, but a missed deadline puts your LLC out of good standing, and after a period of delinquency the DFI can administratively dissolve it. Reinstating a dissolved LLC costs $100 plus $25 for each missed report (current as of October 2026).
Wisconsin LLC Tax Basics
Here is what Wisconsin LLC owners actually owe (current as of October 2026):
- No franchise tax. Wisconsin does not impose a franchise tax or annual LLC tax — a real advantage over states like California ($800/year) or Delaware ($400/year LLC tax).
- State income tax (pass-through): Most LLCs do not pay entity-level income tax; members report their share of profits. Wisconsin’s individual income tax is progressive, ranging from 3.54% to 7.65%. Multi-member LLCs file Wisconsin Form 3 (Partnership Return); LLCs taxed as corporations file Form 4 or 6.
- Sales tax: 5% state rate plus applicable county/local taxes. Register for a seller’s permit if you sell taxable goods or services into Wisconsin.
- Federal taxes: A single-member LLC defaults to disregarded-entity status (income reported on the owner’s return); a multi-member LLC defaults to partnership taxation. Either can elect S-corp or C-corp taxation with the IRS if the math favors it.
Foreign owners: the tax-treaty status of your country of residence affects withholding and reporting. For the full picture, see US LLC taxes for foreigners, and consider a cross-border accountant before your first tax year ends.
Wisconsin LLC for Non-US Founders
Wisconsin is a solid pick for non-US founders: low fees, no franchise tax, fast online filing, and no state-level requirement that owners or managers be US residents. A few things to plan for specifically:
- You need a Wisconsin registered agent. You cannot serve as your own agent without a Wisconsin address, so a professional service is the one recurring cost you cannot avoid.
- EIN by fax. Without an SSN, file Form SS-4 by fax to the IRS after your Articles are accepted. Start early — it is the slowest step for foreign founders.
- Form 5472. As the sole foreign owner, this annual IRS information return (with a pro forma Form 1120) is mandatory. Penalties for missing it are steep — calendar it alongside the Wisconsin annual report.
- No BOI filing for US-formed LLCs. Under FinCEN’s final rule of August 11, 2026 (effective August 14, 2026), US-formed companies are permanently exempt from Corporate Transparency Act beneficial ownership reporting — even when owned by foreign nationals.
- Banking is the hard part. US banks generally want an EIN, your filed Articles, an operating agreement, and often an in-person visit. Wise Business is the default first pick for founders in blocked countries — Mercury maintains a published prohibited-country list of roughly 48 countries (including Pakistan, Bangladesh, Nigeria, and the Philippines), so check Mercury’s eligibility list before applying.
Frequently Asked Questions
How much does it cost to start an LLC in Wisconsin?
The DFI charges $130 to file Articles of Organization online (plus a $1 portal fee) or $170 by mail, current as of October 2026. Add $25/year for the annual report and the cost of a registered agent if you use a service. With no franchise tax, Wisconsin’s total first-year state cost can be as low as $156.
How long does it take to get an LLC in Wisconsin?
Online filings through the DFI’s One Stop Business Portal are usually accepted on receipt — often within 1 business day. Mail filings take 5–10 business days. Expedited service is available for +$100 (next business day), +$250 (same day), or +$500 (same hour), current as of October 2026.
Do I need a registered agent in Wisconsin if I don’t live there?
Yes. Every Wisconsin LLC must continuously maintain a registered agent with a physical Wisconsin street address — no P.O. boxes, and the agent must be available during normal business hours. Non-resident founders cannot act as their own agent, so a professional registered agent service is effectively mandatory. The agent’s name and address appear on your public filing.
Does Wisconsin require an operating agreement?
No — Wisconsin does not legally require LLCs to adopt an operating agreement. But create one anyway: banks, payment processors, and marketplaces routinely ask for it during verification, and it documents ownership and decision-making, which strengthens your liability protection. It stays in your own records and is never filed with the DFI.
Do I need to file a BOI report for my Wisconsin LLC in 2026?
No. Under FinCEN’s final rule of August 11, 2026 (effective August 14, 2026), companies formed under US law — including Wisconsin LLCs — are permanently exempt from Corporate Transparency Act beneficial ownership reporting, even when owned by foreign nationals. Older articles written before this rule may still say otherwise; they are outdated.
Can a foreigner open a US bank account for a Wisconsin LLC?
It is possible but harder than the formation itself. You will need your EIN, filed Articles of Organization, and operating agreement, and many banks require an in-person visit. Remote-friendly fintech options exist: Wise Business is the default first pick for founders in countries blocked by other providers — Mercury, for example, publishes a prohibited-country list of roughly 48 countries including Pakistan, Bangladesh, Nigeria, and the Philippines, so verify eligibility before applying anywhere.
Conclusion
Wisconsin gives non-US founders one of the best value propositions in the country: $130 to form online, a $25 annual report, no franchise tax, and filings accepted on receipt. The process is fully doable yourself through the DFI’s One Stop Business Portal — but if you would rather have the filing, registered agent, domain, and website handled in one package, Registered Agents Inc forms your Wisconsin LLC for $100 + state fee, including one year of free registered agent service (check current pricing — add-on website, phone, and email tools are $5/month each). File correctly the first time, calendar your annual report, and your Wisconsin LLC will stay in good standing for years.
