Factors Influencing The Formation Timeline Of Wisconsin LLCs

Although there’s an established approval time set by the Wisconsin Secretary of State, several factors can delay the processing period. These include the following:

  • Workload volume: The processing time may be prolonged due to the high filings received by the Secretary of State.

  • Documentation issues: If your application requires additional review or the formation documents contain incomplete and inaccurate data, you would need to correct the mistake and refile the paperwork.

  • Weekends and holidays: The agency only reviews applications during regular business hours. That said, I advise clients to file after the weekend or holiday.
