Michigan Business Tax (MBT) Details

The Michigan Business Tax (MBT), which was signed into law by Governor Jennifer M. Granholm July 12, 2007, imposes a 4.95% business income tax and a modified gross receipts tax at the rate of 0.8%.  Insurance companies and financial institutions pay alternate taxes (see below). The MBT replaces the Single Business Tax, effective January 1, 2008.

On December 4, 2007, Governor Jennifer M. Granholm signed Public Act 145 of 2007 amending the MBT. Although the primary purpose of PA 145 was to institute an MBT surcharge, PA 145 also makes some additional changes, which are detailed in the link below.
