When is the Wisconsin LLC annual report due, and what does it cost?

Every Wisconsin LLC files Form 5 starting the year after organization, in the calendar quarter that holds the anniversary (Jan–Mar → Mar 31; Apr–Jun → Jun 30; Jul–Sep → Sep 30; Oct–Dec → Dec 31) per Form 5-I and Wis.

Wisconsin LLC fee table (re-checked 13 October 2026)

File in Wisconsin if the work is in Wisconsin

A domestic Wisconsin LLC is organized by filing Articles of Organization with the Wisconsin Department of Financial Institutions, Division of Corporate & Consumer Services (Chapter 183). Online filing runs through DFI’s Corporation Formation / WISCorp path. A company already formed somewhere else that wants to transact business in Wisconsin files a foreign registration statement (Form 521) — a different instrument (DFI Corporation Fees: foreign LLC registration $100).

Filing in Wyoming, Delaware, or Georgia does not move Wisconsin work out of Wisconsin. A foreign entity that transacts business here still needs a Wisconsin registered agent and Wisconsin foreign registration, plus the formation state’s agent and report. Home-state filing is the cheaper default for a one-state operator. Multi-state registration overview: Foreign LLC and certificate of authority.

What to have on the desk before opening WISCorp / DFI online filing

Checked against the DFI Corporation Fees table and Form 502 / 5-I on 13 October 2026:

• A distinguishable LLC name ending in LLC, L.L.C., or Limited Liability Company. Search the DFI corporate records before ordering letterhead.
• Articles of Organization details, including the registered agent and Wisconsin street address for the registered office (not a P.O. box alone), plus a principal office address.
• Registered agent who can accept service of process in Wisconsin. See Registered agent basics for a new LLC.
• Organizer information as the current online form requires. Payment follows whatever DFI checkout shows.

No newspaper or other advertising is required on the standard domestic Articles of Organization path. Professional entities and conversions are out of scope for a default 1099 single-member LLC on this page.

File through WISCorp / DFI online filing

The primary path on this page is DFI online filing at dfi.wi.gov (Corporation Formation / WISCorp). File Articles of Organization for a new Wisconsin LLC and pay. The Corporation Fees table lists $130.00 for online organization and $170.00 otherwise. Optional next-day expedite is $100 extra.

Optional assumed-name or other line items belong on the current DFI fee table and checkout screen — this page does not invent add-ons. Pay what the portal shows and keep the receipt.

After the Articles of Organization are filed

Formation with DFI is not a Wisconsin Department of Revenue tax account, a seller’s permit, a city license, or a professional license. Those have their own filings.

The IRS tells applicants to form the state entity first, then obtain an Employer Identification Number. That application on IRS.gov is free.

Wisconsin does not require an operating agreement to be filed with the Articles of Organization. A written agreement still matters between members. Banks often ask for one anyway. See LLC operating agreement basics.

Annual report — $25 online, due in the anniversary quarter

Wisconsin requires an annual report (Form 5) for domestic LLCs. Per Form 5-I: start the year after organization; file in the calendar quarter that holds the organization anniversary (Jan–Mar → due Mar 31; Apr–Jun → Jun 30; Jul–Sep → Sep 30; Oct–Dec → Dec 31). DFI Corporation Fees: $25 online or $40 on paper (re-checked 13 October 2026).

Put the first quarter window on a calendar the day articles are accepted. File from the “File Annual Report” path on dfi.wi.gov. Cross-state renewals: LLC annual report and annual registration. This page does not compute anyone’s tax.

Missing reports lead to administrative dissolution. Overview of admin-dissolve vs reinstate: Reinstate an administratively dissolved or revoked LLC.
