Treasury: State Income Tax Season Begins on Jan. 27Contact: See contact information below.
Jan. 23, 2020
Michigan taxpayers can begin to file state income tax returns on Jan. 27, according to the Michigan Department of Treasury.
Individuals can file their state income tax return online, with a tax professional or by mailing in paper forms and documentation. All state income tax returns and payment of any taxes owed must be received by April 15, 2020.
All employers are required to mail previous year wage statements – W-2s and 1099s – to their employees by Jan. 31. End-of-the-year pay stubs should not be used when filing a state income tax return because they are typically not an accurate reflection of all income received.
Taxpayers who rush to file without all the necessary paperwork will need to file an amended return later. State income tax returns filed without the required paperwork will be placed on hold for future processing and review.
For the benefit and convenience of taxpayers, both the beginning and end of the individual income tax filing season are the same as the Internal Revenue Service.
