What does NOT require registration in Wisconsin 11 activities

Wisconsin carves 11 activities out by statute. On their own, none of them requires a foreign LLC to register.

  • Maintaining, defending, mediating, arbitrating, or settling an action or proceeding
  • Carrying on internal company affairs, including holding meetings of members or managers
  • Maintaining accounts in financial institutions
  • Maintaining offices or agencies for transfer, exchange, and registration of the company's securities
  • Selling through independent contractors
  • Soliciting or obtaining orders, if the orders require acceptance outside Wisconsin
  • Creating or acquiring indebtedness, mortgages, or security interests in property
  • Securing or collecting debts, enforcing security interests, and holding or maintaining the property
  • Conducting an isolated transaction that is not one of similar transactions
  • Owning property, and nothing more
  • Doing business in interstate commerce

Under Wis. Stat. Section 183.0905, as rewritten by 2021 Wis. Act 258 effective 2023-01-01. There is NO time limit on the isolated-transaction carve-out; the repealed Section 183.1003 did carry a 30-day cap and is still widely cited. Note that the act is numbered to the 2021 session although it was published in 2022.
