Step-by-Step Wisconsin LLC Instructions

  1. Check Name Availability

    The legal name of your LLC may not conflict with any other registered name. Check availability of your desired name by conducting a name search.

    Name Search: Wisconsin Department of Financial Institutions (DFI) - Corporation Section
    Name search
    Name Reservation: Optional

    The name of a limited liability company as set forth in its articles of organization must contain the words "limited liability company" or "limited liability co." or end with the abbreviation "L.L.C." or "LLC". 
    Wisconsin Statutes §183.0103

  2. Appoint a Registered Agent

    Before you officially file to create your Wisconsin LLC, you will need to decide who your Wisconsin registered agent will be. A registered agent is a business's legal appointee to receive notice of lawsuit and other legal or government notices.

    State law requires every LLC to have a registered agent. The registered agent is designated when you file Wisconsin articles of organization with the Wisconsin Department of Financial Institutions (DFI) - Corporation Section.

    Our reliable registered agent service fulfills this requirement. You get:

    • Same-day documents from our local office in Appleton
    • Immediate online access to state forms with our address and, where required, our signature
    • Annual fees from $89 to $99 per state with no additional charges

    Fact Checked:6/13/17
  4. Establish Company Records

    Your LLC must keep correct and complete books and records. Your filed articles of organization are the first documents for your LLC’s records. Your LLC will generate many other official records such as:

    • Meeting minutes
    • Operating agreement
    • EIN verification letter
    • Amendments and other filings made to the LLC throughout its lifetime

    Organizations need a secure, centralized tool for managing and accessing sensitive records. Our Records Manager software offers a simple, efficient way for LLCs to store records, track members and managers, and customize meeting notifications.

  5. Create the Operating Agreement

    Draft an Operating Agreement (potentially using a template) which is the governing document for the LLC. It defines the formalities of how the LLC will run itself such as holding an annual meeting. You will review and adopt the agreement at your organizational meeting.

  6. Hold the Organizational Meeting

    The first meeting of the members of the LLC is the organizational meeting. You will need your filed articles of organization and your operating agreement in order to conduct this meeting. Keep minutes of this meeting and store them in your company record book.

  7. Get a Federal Employer Identification Number (EIN)

    If your LLC has more than one member or will hire employees, it must obtain an EIN. An EIN is also often required to open a bank account.

    Agency:Internal Revenue Service (IRS)

    IRS Form SS-4

    Filing Method:

    Mail, phone, fax, or online.

    IRS fee:



    Immediately online or by phone. 4 business days by fax. 4-5 weeks by mail.


    The IRS website is only available during certain hours. Print your EIN before closing your session. For additional guidance, see IRS Pub 1635: Understanding Your EIN.

    Fact Checked:8/28/19
  8. Get Wisconsin State Tax Identification Numbers/Accounts

    Wisconsin offers a consolidated registration application for new business state tax registration.

    Submit to:
    Wisconsin Department of Revenue
    Business Tax Registration Common Questions
    Form BTR-101: Application for Business Tax Registration
    Filing Method:
    Mail, fax, or online
    ~15 business days
    Business Tax Registration (BTR) must be renewed after 2 years for a fee of $10.
  9. Consider Electing S-Corp or C-Corp Taxation

    By default, your LLC receives pass-through taxation and the vast majority of LLCs keep this tax classification. Some LLCs benefit from electing S-Corp or C-Corp tax treatment:

    • S-Corp treatment can help owner-employees who earn more than ~$75,000 per year save on self-employment taxes. File Form 2553: S-Corp Election.
    • C-Corps suffer from double taxation: the corporation pays taxes on profits then members pay taxes on their distributions. If profits exceed $250,000 per owner, you provide employee benefits, or you will re-invest most of your profit in the business, you may benefit from the low tax rates on retained earnings under C-Corp treatment. File Form 8832: C-Corp Election.
  10. Obtain Business Licenses & Permits

    To run your business legally, you must obtain applicable licenses and permits. The easiest way to navigate the wide range of federal, state, and local requirements is to search by your business type and locality using the Small Business Administration Business License & Permit look-up tool.

    Wisconsin Business License

    Not required

    General Business License licensure is not required on the State level in Wisconsin.

    Wisconsin does not have a general business license at the state level, but local licenses are often required.

  11. Ongoing Filings to Maintain Your LLC

    You must file federal and state tax returns.

    Many states also require business entities to file an annual report to maintain good standing with the secretary of state. If an annual report is required for LLCs formed in Wisconsin, view the table below.

    Domestic Wisconsin Corporation Annual Report Requirements:

    Agency:Wisconsin Department of Financial Institutions (DFI) - Corporation Section

    Use the form that WDFI mailed your registered agent or file online. Annual report forms are not available for downloading from the WDFI website. Call (608) 261-7577 to request a replacement form.

    Filing Method:

    Mail or online.

    Agency Fee:

    $25 online or $40 by mail. 


    Annually by the end of the registration anniversary quarter. So if you incorporated or foreign-qualified on February 15, then your annual report is due every year by the end of the first quarter on March 31. The due dates are March 31, June 30, September 30, and December 31.


    Wisconsin Statutes § 180.1921

    • Anyone with authority may file.
    • Original signatures are not required.
    Fact Checked:1/11/21

    For more details, see our Wisconsin annual report information center page.

    As your LLC grows, you will need to demonstrate your company’s good standing to banks, customers, and other state agencies. After all the work involved in forming your Wisconsin LLC, don’t let a missed annual report filing cause your new business to fall out of compliance.

    Tracking and filing annual reports on your own can be time consuming and lead to accidental lapses. Protect your LLC’s good standing with Managed Annual Report Service, which tracks and automatically files reports on time, every time, so you can focus on your business.
