Is OSB right for me?

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.

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 agency 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.
