Michigan lawmakers approved significant corporate tax reform last year that went into effect at the beginning of 2012. Previously Michigan had a dual corporate tax system called the Michigan Business Tax (MBT). Under the MBT corporate profits were taxed at a rate of 4.95 percent, and all transactions were taxed at a rate of 0.8 percent (a gross receipts tax, or GRT). In addition, there was a 21.99 percent surcharge on the total tax liability from the MBT. We had been critics of the MBT, specifically the gross receipts tax, since it was implemented in 2008. GRTs are an outdated, economically damaging tax that leads to tax pyramiding (read more here).
