The State of Wisconsin requires you to file an annual report for your LLC. Annual report forms or notifications are automatically sent to your LLC’s registered agent and office.
File your annual report online at the DFI website. The annual report is due at the end of the calendar quarter of the anniversary month of your LLC’s formation.
For example, if your LLC was formed on July 15 then your report would be due by September 30. The current filing fee is $25. (Non-Wisconsin LLCs pay a higher fee.)
