You can do this through Michigan Treasury Online (MTO) using the Manage Business Registration Service if you are already connected to the business taxes account. Alternatively, you can download and mail Form 163 – Notice of Change or Discontinuance.
Until tax types and/or the Treasury business taxes account is discontinued, you must file returns for taxes the entity is registered for (even if the tax obligation is $0). If you are unclear about your business’ registration status, contact the Business Taxes Contact Center, Registration Division.
