Tax Rates and Liability

How is my tax rate calculated?

The tax rate is a combination of Account Building Component (ABC), Non-chargeable Benefits Component (NBC) and Chargeable Benefits Component (CBC).

What may increase the tax rate:

If you have benefits charges
If your payroll increases in the computation period
If you have a negative reserve (paid more for benefits than we've collected in tax)
If you have missing report(s) in the computation period (non-reporting penalty is added to the tax rate).

I don't have employees anymore - why am I receiving a bill?

If you no longer have employees, you must notify the Unemployment Insurance of your change in payroll by completing the Notice of Change (Form 1772). This form is found at www.michigan.gov/uia in the forms section and mail or fax the document. Or you may complete the Notice of Change form in your MiWAM account.

What do I do if I disagree with my tax rate?

You can log into the MIWAM account and select tax protest. Please make sure that you complete all necessary information to be considered in the review of your account.
