In January 2015, the Michigan Department of Treasury began to process current year SUW tax returns with a new online system. As a result of this new processing system, there will be changes to the SUW forms and to the way taxpayers can file and make payments for returns in tax year 2015 and beyond. The new bundle of e-services is called Michigan Treasury Online (MTO). Business taxpayers have 24/7 access to their accounts and will be able to file returns electronically, pay SUW tax due in one convenient transaction and make routine account changes.
However, although the income tax withholding rate remains at 4.25% for tax year 2015 but the personal exemption amount changed to $4,000, employers should continue to use the 2014 Michigan income Tax Withholding Tables
