Is OSB right for me?

Fraudulent Filing Notice: It is a Class I felony in Wisconsin for a person to knowingly file a false corporate document if the person intends that document to be filed or delivered to the Department of Financial Institutions. The Department reports fraudulent filings to the Department of Justice or local district attorneys for criminal prosecution. See Wis. Stat. Sections 178.0124, 180.1029, 181.0129, and 185.82.

Let's see if OSB is right for you. Check each that are true:

I have not already filed the appropriate Articles (Incorporation/Organization) for this business with the DFI.

I have not already created a tax registration for this business with the DOR.

My business type is one of the following: Business Corporation, Statutory Close Corporation, Limited Liability Company.

I am not trying to organize an LLC as a Student Entrepreneur (See eligibility details).

My business is not a bank that would need to register with the Division of Banking instead (not handled by this system)

My business is not an insurance company that would need to register with the Commissioner of Insurance instead (not handled by this system)

My business is not already registered in a state or jurisdiction other than Wisconsin.

If you are organizing an LLC as a Student Entrepreneur:: Students meeting all of the eligibility requirements for a Student Entrepreneur fee waiver must file form 502SE on paper to receive a waiver of the filing fee.

If your business is a bank:: Banks need to register with the Division of Banking, and are not handled by this system.
If your business is an insurance agency:: Insurance agencies need to register with the Commissioner of Insurance, and are not handled by this system.
