If you have recently expanded your business into this state, or if you’re considering doing so, understanding the cost of apportionment is important to help you accurately report earnings to the IRS and local governments. 

  • C Corporations

    • Filing Requirements
      • The Michigan Corporate Income Tax (CIT) imposes a 6% corporate income tax on C corporations and taxpayers taxed as corporations federally. The CIT has one credit, the small business alternative credit, which offers an alternate tax rate of 1.8% of adjusted business income. There are no other credits, except those under the MBT election (addressed below). Insurance companies and financial institutions pay alternative taxes. The CIT replaces the Michigan Business Tax (MBT) for most taxpayers, effective January 1, 2012. Taxpayers with less than $350,000 in allocated or apportioned gross receipts and/or less than or equal to $100 in annual liability are not required to file or pay the CIT. The gross receipts threshold does not apply to financial institutions or insurance companies.
    • Allocation & apportionment
      • One Factor Formula: Sales factor
      • Market-based apportionment
      • Michigan follows the market-based rule in sourcing receipts from the performance of services to the state. Sales from the performance of services are sourced to Michigan if the recipient of the service receives all of the benefits of the service in Michigan. If the benefit of the service is received in more than one state, the sale is sourced to Michigan based on the proportion of the benefit of service received in Michigan. The rule applies to both the corporate income tax and the Michigan Business Tax (for taxpayers with certificated credits that elect to file and pay under the Michigan Business Tax).
  • Employees & individual filers

    • The following individuals are required to file a 2021 Michigan individual income tax:
      • File a return if you owe tax, are due a refund, or your AGI exceeds your exemption allowance. You should also file a Michigan return if you file a federal return, even if you do not owe Michigan tax. This will eliminate unnecessary correspondence from Treasury.
      • If your parents (or someone else) can claim you as a dependent on their return and your AGI is $1,500 or less if single or married filing separately or $3,000 or less if filing a joint return, you do not need to file a return unless you are claiming a refund of withholding.
      • Important: If your income subject to tax (MI-1040, line 14) is less than your personal exemption allowance (line 15) and Michigan income tax was withheld from your earnings, you must file a return to claim a refund of the tax withheld.
