In Michigan, a UBG with standard members must file Form 4567. A Designated Member (DM) must file the return on behalf of the standard members of the group. In a parent- subsidiary controlled group, the controlling member must serve as DM if it has nexus with Michigan.
The CIT replaces the Michigan Business Tax; however, MBT taxpayers who have received or been assigned certain certificated credits may elect to continue to file under the MBT rather than the new CIT in order to claim such credits.
