Starting an LLC in Wisconsin Is Easy With These 5 Steps
STEP 1: Name your Wisconsin LLC
Choosing a company name is the first and most important step in starting your Wisconsin LLC. Be sure to choose a name that complies with Wisconsin naming requirements and is easily searchable by potential clients.
1. Follow the naming guidelines:
- Your name must include the phrase “limited liability company” or one of its abbreviations (LLC or L.L.C.).
- Your name cannot include words that could confuse your LLC with a government agency (FBI, Treasury, State Department, etc.).
- Restricted words (e.g. Bank, Attorney, University) may require additional paperwork and a licensed individual, such as a doctor or lawyer, to be part of your LLC.
- Your name must be distinguishable from any Wisconsin limited liability company (LLC), corporation, limited liability partnership (LLP), or limited partnership (LP).
2. Is the name available in Wisconsin? Make sure the name you want isn't already taken by doing a name search with the State of Wisconsin's Business Entity Search.
