How to file a Wisconsin annual report

Wisconsin requires most business entities to file an "Annual Report for Department of Financial Institutions" to maintain their legal status and good standing with the state. For LLCs, this filing is commonly referred to as the "Wisconsin LLC Annual Report," while corporations must submit their report using the official state designation.

The annual report serves as your business's yearly check-in with the Wisconsin Department of Financial Institutions (WDFI), ensuring the state maintains current information about your entity's structure, management, and contact details. This mandatory filing demonstrates ongoing compliance with Wisconsin business laws and keeps your entity authorized to conduct business within the state.

Who must file?

Wisconsin law requires most registered business entities to file an annual report with the Wisconsin Department of Financial Institutions (WDFI) to maintain their legal status and keep business information current with the state. The list of required entities includes:

Limited partnerships (LPs) and limited liability partnerships (LLPs) are not required to file annual reports in Wisconsin. Additionally, sole proprietorships and general partnerships (unless they elect to be an LLP) are not required to file. 

Authorized filers include:

  • Business owners, members, or partners
  • Corporate officers and directors
  • LLC managers and members
  • Registered agents
  • Attorneys representing the entity
  • Accountants with proper authorization
  • Third-party service providers with written authorization

How to file

Wisconsin offers two primary methods for filing your annual report: online filing through the Wisconsin One Stop Business Portal (recommended) and filing by mail as an alternative option.

Here’s the step-by-step online filing process:

  1. Access the Wisconsin One Stop Business Portal at the official WDFI website
  2. Search for your business using your entity name or ID number (no account required for basic filings, though a WAMS ID is recommended for advanced features)
  3. Select your business from the search results to proceed with filing
  4. Review and update your business information, including addresses, management details, and registered agent information
  5. Complete all mandatory fields and double-check for accuracy to avoid processing delays
  6. Submit your completed report and pay the required filing fee online
  7. Save your digital confirmation receipt for your records

If you prefer to file by mail, print the appropriate annual report form from the Wisconsin Department of Financial Institutions website, complete it manually, and mail it with payment to the WDFI

Processing timeframes:

  • Online filing: Immediate to 5 business days during peak periods
  • Mail filing: Up to 5 business days after receipt by the state
  • Online filing provides instant confirmation, while mail filing may result in delayed acknowledgment

Due dates and deadlines

Wisconsin uses a unique quarterly deadline system based on when your entity was originally formed or registered, rather than a universal annual deadline used by many other states.

Annual reports are due by the last day of the quarter in which your entity was formed or registered. 

Entity Type Formation/Registration Date Annual Report Due Date
Domestic LLCs January 1 – March 31 March 31
Domestic LLCs April 1 – June 30 June 30
Domestic LLCs July 1 – September 30 September 30
Domestic LLCs October 1 – December 31 December 31
Domestic Corporations Same quarterly system Same quarterly system
Foreign Entities Any date March 31
Nonprofit Corporations Same quarterly system Same quarterly system

Filing fees

Wisconsin's annual report fees vary by entity type and filing method, with online filing generally offering cost savings compared to mail submission.

Filing Method Entity Type Fee Notes
Online LLCs/Corporations $25 Standard annual fee
Online Nonprofit Corporations $25 May have reduced fees
Mail LLCs $25 Same as online
Mail Corporations $40 Higher fee for paper filing
Mail Nonprofit Corporations $25 Check the current fee schedule

Required information

Filing your Wisconsin annual report requires specific information about your business structure, management, and contact details that must be current and accurate. These requirements include: 

  • Complete legal entity name as registered with the state
  • Entity identification number (assigned by WDFI)
  • Principal business address (street address required, not P.O. boxes)
  • Registered agent name and Wisconsin street address
  • Current registered office address in Wisconsin
  • Brief description of business activities or purpose

Entity-specific requirements:

  • Corporations: Names and addresses of all directors and principal officers, authorized share structure including classes and par value, state or country of incorporation
  • LLCs: Management structure designation (member-managed or manager-managed), names and addresses of managers if manager-managed
  • Nonprofits: Names and addresses of principal officers and board members, confirmation of nonprofit status and purpose
  • Limited Partnerships: Names and addresses of general partners, partnership structure details

Electronic signatures are accepted for both online and mail submissions. However, only corporate officers (such as president, secretary, or treasurer) are authorized to sign annual reports in Wisconsin.

Consequences of not filing

Missing your Wisconsin annual report deadline immediately strips your entity of good standing status with the Wisconsin Department of Financial Institutions. This creates immediate barriers to:

  • Obtaining certificates for business transactions 
  • Accessing banking services
  • Renewing licenses 
  • Entering new contracts

The situation deteriorates rapidly if you remain non-compliant. After one year of non-filing, Wisconsin administratively dissolves domestic entities or revokes foreign entities' authority to do business in the state.

Reinstatement requires filing all past-due annual reports along with their fees, plus paying additional administrative reinstatement fees to the WDFI.

FAQs about Wisconsin’s annual report

Can I file annual reports for multiple years at once?

No, Wisconsin requires annual filing only. You cannot file multiple years in advance, and each year's report must be submitted by its specific deadline to maintain continuous good standing.

Can I file my annual report early or request an extension?

Yes, you can file your annual report early, and this is actually recommended to avoid last-minute complications. However, Wisconsin does not grant extensions for annual report filings.

What if I need to amend information after filing my annual report?

If you discover errors after filing, you can submit corrections through the Wisconsin One Stop Business Portal or by contacting the WDFI directly. Minor corrections may be processed quickly, while significant changes might require additional documentation and fees.

Who is authorized to file my annual report on my behalf?

Officers, directors, managers, members, registered agents, and authorized third-party service providers can file on behalf of your entity. Attorneys and accountants may also file with proper authorization.
