How to Form an LLC in Wisconsin: Steps & Cost (2026)

Fact-checked by the LegalGlass editorial team against primary sources · Published Aug 6, 2026 · Last updated Aug 6, 2026

You form a Wisconsin LLC by filing Articles of Organization (Form 502) with the Wisconsin Department of Financial Institutions and paying the $130 online fee ($170 by paper). You must name a Wisconsin registered agent, and each year you file an annual report ($25 online) with the DFI. Wisconsin has no separate franchise tax, but LLC income flows to the owners' Wisconsin tax returns.

Wisconsin Agency and Form: DFI, Form 502

A Wisconsin LLC is created by filing Articles of Organization with the Wisconsin Department of Financial Institutions (DFI). The correct document for a domestic limited liability company is Form 502, provided by the DFI's Division of Corporate and Consumer Services. Filing this document - and the DFI's acceptance of it - is the legal act that brings the LLC into existence under Wis. Stat. § 183.0201, part of Chapter 183, the Wisconsin Uniform Limited Liability Company Law.

Form 502 asks for the LLC's name, its registered agent and registered office, whether the company is member-managed or manager-managed, and the name and address of each organizer. The name must contain an LLC designator (such as "LLC," "L.L.C.," "Limited Liability Company," or "Limited Liability Co.") and be distinguishable in the DFI records from existing entity names. You can check name availability and file through the DFI's online business formation system, which is the fastest route; a mailed paper Form 502 is also accepted. This guide covers the general Wisconsin process; for the national overview see how to form an LLC and what an LLC is.

How to Form a Wisconsin LLC, Step by Step

Forming a Wisconsin LLC is a six-step process centered on Form 502. Each step below corresponds to a requirement of Chapter 183 of the Wisconsin Statutes or a federal tax rule.

1. Choose and check your LLC name. Select a name that includes an LLC designator and is distinguishable from names already on file with the DFI. Verify availability through the DFI corporate records search. If you are not ready to file, you may reserve a name for 120 days by filing a Name Reservation Application. Confirm the name also does not infringe a federal trademark.
2. Appoint a Wisconsin registered agent. Every Wisconsin LLC must name a registered agent with a Wisconsin street address (the registered office). The agent may be an individual Wisconsin resident or an entity authorized to do business in the state.
3. File the Articles of Organization (Form 502). Submit Form 502 to the Wisconsin DFI and pay the $130 online fee, or $170 by paper. File online through the DFI portal for the quickest turnaround. Once the DFI accepts the articles, your LLC legally exists.
4. Adopt an operating agreement. Wisconsin does not file or require you to submit an operating agreement, but one is strongly recommended to set ownership percentages, management structure, voting, and profit distribution. Chapter 183 supplies default rules only where your agreement is silent. See what an LLC is for how the agreement fits the structure.
5. Get an EIN and register for Wisconsin taxes. Apply for a free federal EIN from the IRS, then complete Wisconsin Business Tax Registration with the Department of Revenue if you will sell taxable goods, have employees, or owe other state taxes.
6. File your annual report. Each year, file the Wisconsin annual report with the DFI and pay the $25 online fee ($40 by paper). The report keeps your entity in good standing.

After these steps, open a business bank account (banks generally ask for the accepted Articles of Organization and the EIN) and calendar your annual report deadline so the entity stays in good standing.

Wisconsin LLC Filing Fees (2026)

The core cost of a Wisconsin LLC is the Articles of Organization fee - $130 online or $170 by paper. The table below lists the state fees most new LLCs encounter, each verified against the Wisconsin DFI fee schedule or the Wisconsin Department of Revenue. Amounts are effective for 2026 and are set by the state, not by any filing service.

Expedited processing is available from the DFI for an additional $100 for next-day handling. A name reservation is also available for 120 days; confirm the current reservation fee on the DFI fee schedule before you file. For a full breakdown, see Wisconsin LLC cost and the national how much an LLC costs.

Wisconsin Registered Agent Requirement

A Wisconsin registered agent is the person or entity your LLC designates to receive service of process, tax notices, and official state correspondence. Wis. Stat. § 183.0115 requires every domestic LLC to designate and continuously maintain a registered agent and a registered office in Wisconsin. You name the initial agent directly on Form 502.

The agent must be an individual who resides in Wisconsin, or a domestic or foreign entity authorized to transact business in the state, and must have a Wisconsin street address - a post office box alone does not satisfy the registered office requirement. You may act as your own registered agent, name a member or manager, or hire a commercial registered agent service. To change agents later, file a Statement of Change of Registered Agent with the DFI for $10 online ($25 by paper). Failing to maintain a registered agent can lead the DFI to administratively dissolve the LLC. See Wisconsin registered agent requirements and the national registered agent overview for detail.

Wisconsin LLC Annual Report

Every domestic Wisconsin LLC must file an annual report with the DFI under Wis. Stat. § 183.0212. The fee is $25 when filed online and $40 by paper (the paper filing carries a surcharge). Unlike some states, Wisconsin does not tie the deadline to a single statewide date.

Instead, the report is due at the end of the calendar quarter in which the LLC was organized. That means the deadline is March 31 for LLCs organized in the first quarter, June 30 for the second quarter, September 30 for the third quarter, and December 31 for the fourth quarter. You can confirm your quarter by looking up the LLC's formation date in the DFI corporate records. The report updates the LLC's principal office, registered agent, and management information. Missing it puts the entity at risk of administrative dissolution. Full detail is in Wisconsin LLC annual report and taxes.

EIN, Seller's Permit, and Wisconsin Taxes

A federal Employer Identification Number (EIN) is issued free by the IRS and is used to open a bank account, hire employees, and file taxes. By default, the IRS treats a single-member LLC as a disregarded entity (taxed on the owner's return) and a multi-member LLC as a partnership; either can elect corporate or S-corporation treatment by filing the appropriate IRS form. Most Wisconsin LLCs need an EIN, and one is required if the LLC has more than one member or any employees.

If your LLC sells taxable goods or services in Wisconsin, you must complete Business Tax Registration with the Wisconsin Department of Revenue and obtain a seller's permit before making retail sales. The Business Tax Registration fee is $20 and covers a two-year period, with a $10 renewal for each later two-year period; the same $20 covers a seller's permit, use tax certificate, employer withholding, and most other DOR permits. Wisconsin has no separate LLC franchise tax; instead, LLC income passes through to the members and is taxed on their Wisconsin individual returns unless the LLC elects corporate treatment. See business licenses in Wisconsin and the national business license overview for what else may apply.

Penalties for Missing Wisconsin Requirements

Missing Wisconsin requirements carries real consequences. If an LLC fails to file its annual report or maintain a registered agent, the DFI can administratively dissolve the entity after notice. A dissolved LLC loses the right to carry on business except to wind up, and its name becomes available to others. Reinstatement generally requires filing the delinquent reports and paying the associated fees.

On the tax side, operating without a required seller's permit, or failing to remit collected sales tax, exposes the business to Department of Revenue penalties and interest. Keeping your registered agent, annual report, and DOR tax accounts current is the simplest way to avoid all of these outcomes. Because these are general rules, confirm your specific situation with the DFI or a qualified professional.

Closing a Wisconsin LLC

To close a Wisconsin LLC properly, you wind up the business, settle debts and taxes, and file a Statement of Dissolution or Termination (Form 510) with the DFI for $20 online ($35 by paper), following subchapter VII of Chapter 183. Simply abandoning the LLC leaves annual report obligations running and can lead to administrative dissolution instead of a clean close. See how to dissolve an LLC in Wisconsin and the national how to dissolve an LLC for the full wind-up steps.
