Why is this important?
To maintain compliance with state payroll tax regulations, you must provide the following information before you can use OnPay to run payroll:
- State Employer Identification Number and state/local tax IDs
- Tax rates - State tax offices set these rates based on the type, age, and size of your business
- TPA and power of attorney - Most tax offices require this before we can submit quarterly wage reports and deposits on your behalf
This information must be provided and maintained by you in order for OnPay to accurately file and deposit tax payments for your company. OnPay is not responsible for any penalties or interest that incur due to missing or incorrect company tax information.
Each state has its own requirements, so if you pay employees in more than one state, you’ll find separate tax guides for each state.

Where you can find the tax account numbers you need
If you are an existing employer who has previously run payroll in Michigan, you likely already have the IDs and online accounts needed for OnPay to process your tax filings.
If you are a new employer in Michigan, you will need to register your business with the Michigan Department of Treasury and the Michigan Department of Labor. This must be completed for OnPay to be able to file and pay your Michigan taxes.

You can find your MI Withholding Tax ID Number on any notices you've received from the Department of Treasury. This number is always the same as your company's FEIN.

The Michigan Department of Labor assigns non-qualifying employers an unemployment wage base of $9,500.

If you've been assigned a wage base of $9,500 by the Department of Labor, submit a request* to have this rate adjusted for your account. Unless notified, OnPay is not responsible for any penalties or fees that result from the underpayment of this tax due to wage base.
