The Michigan Application for Certificate of Authority by Foreign Limited Liability Companies is a form that is required to be filed by limited liability companies (LCS) that are registered in another state or country and are looking to do business in Michigan. This document must be filed with the Department of Licensing and Regulatory Affairs in order for the LLC to be recognized as a valid entity in Michigan and to obtain a Certificate of Authority. The Michigan Application for Certificate of Authority by Foreign Limited Liability Companies is a two-part form that includes the Michigan LLC Certificate of Authority Application and the Michigan LLC Tax Registration Form. The first part of this application includes basic information about the foreign LLC, such as its name, the state or country of formation, and the name and address of the LLC's registered agent. The second part of the application is the Michigan LLC Tax Registration Form, which is used to register the LLC for Michigan taxes. There are two types of Michigan Applications for Certificate of Authority by Foreign Limited Liability Companies: initial application and annual renewal. An initial application is used to register a foreign LLC to do business in Michigan for the first time, while an annual renewal is used to maintain the LLC's authorization to do business in Michigan.
