Domestic LLC Formation Filing Requirements in Wisconsin

At a glance

Requirements one by one

Governing law and filing record

Wisconsin uses Articles of Organization under the Wisconsin Uniform Limited Liability Company Law, Chapter 183. One or more organizers deliver the articles to the Department of Financial Institutions for filing under Wis. Stat. § 183.0201.

Organizer and signature

An organizer may be an individual or another legal or commercial entity; the organizer need not be a member or owner. The articles publicly state every organizer's name and address. At least one person acting as an organizer signs, and the filing states each individual signer's name and capacity under § 183.0203 and § 183.0206.

Current paper Form 502 also asks for the individual's name who drafted the document when it was executed in Wisconsin, or an indication that it was not executed in Wisconsin.

Required entity and purpose terms

The name needs an approved LLC or limited-company designator and must be distinguishable in DFI's records under § 183.0112. The articles also state that the company is organized under Chapter 183.

Purpose is optional in the articles. Wis. Stat. § 183.0108 permits any lawful purpose, whether or not for profit, subject to other laws governing a regulated business. The statute gives the LLC perpetual duration.

Addresses and service fields

The filing states the principal office's street and mailing addresses. The principal office need not be in Wisconsin.

The initial registered-agent fields are more detailed: name, street address, mailing address, and email. The registered office must be a physical Wisconsin street location, not solely a P.O. box, mailbox service, or telephone-answering service under § 183.0115.

Management and owner disclosure

The articles may optionally state that one or more managers will manage the LLC. They do not name the managers or members and do not require a beneficial-owner list. Every organizer is named and addressed, but organizer status is a formation role rather than an ownership designation.

Optional and restricted provisions

Section 183.0201(3) permits a manager-management statement, a purpose clause, governance provisions, power limits, par value, and provisions permitted or required in a written operating agreement. Added provisions must be consistent with law. Form 502 places them on sequentially labeled attachment pages.

Filing method, fee, and attachments

The statutory online filing fee is $130. Wisconsin permits a larger paper fee, and current paper Form 502 sets it at $170 for a mailed original. The paper form offers optional expedited service for an additional $100.

No attachment is required for ordinary minimum articles. Additional provisions use labeled pages. A narrow student-startup waiver applies when all members and any nonmember organizers meet the student-entrepreneur conditions in § 183.0122(2)(d).

Formation and effective date

The LLC forms when the articles become effective. Ordinarily that is the DFI receipt date at the time stated in the articles, or at close of business if no time is stated. A delayed date and time may be no more than 90 days after receipt under § 183.0207.

DFI's filing is conclusive proof that the LLC was organized and formed under Chapter 183.

Publication and initial follow-up

Chapter 183 and current Form 502 require no newspaper or database publication, proof filing, or separate initial report. The recurring annual report starts in the year after the calendar year in which the articles became effective and is filed during the anniversary quarter under § 183.0212(3)(a).

What trips people up

The organizer list is public even though the owner list is not. Every organizer's name and address appears in the articles, but members and managers are not listed merely because they hold those roles.

Agent email is mandatory. The articles require the registered agent's email along with the street and mailing addresses. The principal office has no email field in the statutory list.

Online and paper fees differ. The statute sets $130, while § 183.0122(2)(c) allows a larger paper charge and current Form 502 uses $170.

Common questions

Must an organizer own the LLC? No. Chapter 183 defines organizer as the person acting to form the LLC and defines person broadly; it does not make the role dependent on membership.

Must the articles say whether managers will manage? No. The manager-managed statement is optional. If used, it does not require manager names.

Is the annual report filed immediately? No. The first annual report cycle begins in the year after formation, not as an attachment or immediate post-filing step.
