The Michigan Department of Treasury has revised a notice stating that while disregarded entities for federal tax purposes are required to file Michigan Business Tax (MBT) returns, the due date to file the returns is extended to October 31, 2011 (previously, June 30, 2011).
The notice had created considerable confusion among tax practitioners. Also, many unintended consequences have been uncovered. A MBT technical corrections bill may be introduced into the legislature soon. The MBT technical corrections bill will have language to conform the MBT filing method to the federal filing method.
