Reserve Your Name
You can optionally reserve your LLC name in Wisconsin for up to 120 days before you officially register it. This prevents other businesses from registering your name until you have the opportunity to register it yourself.
Name reservations can be filed by mail with the Wisconsin Department of Financial Institutions. The filing fee is $15.
Wisconsin Naming Requirements
Some key guidelines for Wisconsin LLC names include:
- Your name must contain the phrase “limited liability company” or “limited liability co.” or end with one of their abbreviations (LLC or L.L.C.).
- Your name must be distinguishable from any existing business in the state. This includes Wisconsin reserved names.
Keep an eye out for restricted words. These words, such as “FBI” or “Treasury,” are often restricted to keep your LLC from sounding like an official institution.
Additionally, Wisconsin LLC names cannot imply that the LLC was organized for any non-permitted purpose.
For more information, check out Wisconsin’s Department of Financial Institutions website.
Distinguishability
It is important that your name be distinguishable from all other business names. In Wisconsin, a distinguishable name is one that is substantively different from all other existing or reserved business names in the state.
The following differences do NOT make a name distinguishable in Wisconsin:
- Possessives and plurals
- Articles, conjunctions, and prepositions
- Numbers and letters
- Business entity type identifiers
Failure to use a distinguishable name could result in your formation filing being rejected.
