 Withholding Formula (Effective Pay Period 05, 2024)

  1. Subtract the nontaxable biweekly Thrift Savings Plan contribution from the gross biweekly wages.
  2. Subtract the nontaxable biweekly Federal Employees Health Benefits Plan payment(s) (includes dental and vision insurance program and Flexible Spending Account — health care and dependent care deductions) from the amount computed in step 1.
  3. Add the taxable biweekly fringe benefits (e.g., taxable life insurance) to the amount computed in step 2 to obtain the adjusted gross biweekly wages.
  4. Multiply the adjusted gross biweekly wages by the number of pay dates in the tax year to obtain the gross annual wages.
  5. Determine the exemption allowance by applying the following guideline and subtract this amount from the gross annual wages in step 4 to compute the taxable income:

Exemption Allowance = $5,600 x Number of (Personal/Dependent) Exemptions

  1. Multiply the result of step 5 by 4.25 percent to obtain the amount of annual Michigan tax withholding.
  2. Divide the annual Michigan tax withholding calculated in step 6 by the number of pay dates in the tax year to obtain the biweekly Michigan tax withholding.
