Companies Must File an Annual Report with the State of Michigan

Content Arrow

The State of Michigan has changed the notification procedures for filing the Michigan Annual Report for companies. We recommend going to our website, www.miercpa.com, clicking on “Resources," "State and Government Resources," and then "Michigan Business Entity Search” to find the latest annual report filing that the State has on record for your company. If your business entity is not listed as being filed during 2018, then you should file the annual report to avoid your company being dissolved by the State of Michigan. You can start filing your annual report at https://cofs.lara.state.mi.us/corpweb/LoginSystem/ExternalLogin.aspx
