What is and isn't Taxable?
Adjusted Gross Income (AGI) is calculated on your federal income tax return and is the starting point for your Michigan individual income tax return and may include your retirement or pension benefit distribution. AGI is the starting point for the individual income tax return. From there, taxable and nontaxable items are added and/or subtracted from AGI to determine your Michigan taxable income.
MCL 206.30(9),(10), and (11) provides guidance on the retirement benefit subtraction. To determine your allowable retirement or pension subtraction, we must consider (1) if your retirement income is considered a qualified distribution and (2) what your tax treatment options are for a given tax year.
