Michigan participates in the MBT Fed/State e-file program for tax year 2009, and will begin accepting MBT e-file returns in January 2010. Filing of tax returns electronically is Secure, Fast, and Convenient. Treasury is committed to processing MBT e-file returns in less than half the time of paper returns, and account resolution for MBT e-file returns receives priority.

Treasury and its customers continue to benefit from advances in technology that improve efficiencies and enhance the State's tax filing, refund, and audit processes. E-file is a key component in this improvement and enhancement.

Effective January 1, 2010, for the 2009 tax year, software developers producing MBT tax preparation software must support e-file for all eligible MBT forms that are included in their tax preparation software. All eligible MBT returns prepared using software must be e-filed.

You will need to purchase tax preparation software that supports e-file. The IRS and Treasury do not charge for e-filing. There may be fees associated with the commercial software used to prepare and transmit the returns. These packages differ in price and features. View a list of companies that offer e-file software for Michigan and federal business and income tax returns.
