Michigan State Filing Requirements for Businesses-An Overview  \nEach year, businesses operating out of Michigan must report their income taxes to the state and pay taxes to the Michigan State Department to maintain their compliance. To collect income-related information from businesses, the State of Michigan created a separate business income state tax form to be filed with the state. The state forms vary based on whether the business is taxed as a C-Corporation, S-Corporation, partnership, trust, estate, etc.  \nBusiness owners in Michigan must file their state tax forms by the deadline to avoid penalties.  \nHowever, businesses that need additional time to complete their state tax returns can file the state-specific extension form with their designated state agency.  \nKeeping up with all the business requirements at the federal level and the state level can be overwhelming. To help business owners better understand their tax extension options and payment requirements, we created this guide!  \n2. Michigan State Tax Extension Filing Requirements  \nIn addition to filing a federal tax extension Form 7004, businesses operating in Michigan are required to file a separate Business Tax Extension Form to get an extension of time to file their Business Income Tax return.  \n2.1. Tax Extension for Businesses-An Overview  \nEven if the IRS has approved their federal extension, CIT (Corporation Income Tax) and MBT (Michigan Business Tax) filers are still required to file the Michigan  Business Tax Extension Form 4, Application for extension of time to file Michigan Tax returns which extends the deadline up to 4 months, that is last day of the 8th month beyond the original due date.  \nIf you did not file a federal extension, you can still file Michigan Business Tax  Extension Form 4, to get an extension of time to file your state Income Tax returns. Please note, business tax filers (CBT/MBT) should check the box for CBT or MBT based on the business tax they plan to file.  \nPlease be aware, under the Michigan Corporate Income Tax, corporations, insurance companies, financial institutions, and unitary business groups are considered taxpayers.  \n803-514-5155  \n[support@expressextension.com](support@expressextension.com)  \n3  \nFlow-through entities like, S-corporations, partnerships, and trusts, generally are not considered taxpayers under the CIT, unless the flow-through entity elects or is required to file as a C-corporation for federal tax purposes. Or if the business constitutes an insurance company or financial institution.  \n2.1.1.
