Scammers are contacting taxpayers while pretending to be from the Michigan Department of Treasury, using out‑of‑state phone numbers. They may request payments or attempt to trick you into providing your bank account information. Always verify the source before sharing any personal or financial details.
Filing Requirements 4. When are CIT Annual Returns due?
CIT Annual Returns must be filed - and final liability remitted - by the last day of the 4th month after the end of the taxpayer's tax year. Taxpayers (other than Insurance Companies or Financial Organizations) are not required to file a return or pay the tax if their apportioned gross receipts are less than $350,000. The filing threshold is annualized for tax years of less than 12 months. In addition, any taxpayer whose tax liability is $100 or less does not need to file a return or pay the tax.
