Michigan Payroll Tax Details
Square Payroll processes the following per the frequency below to the listed state agencies:
| Agency | Filing | Frequency |
| Michigan Department of Treasury | Withholding Tax Payment | After Every Pay Run |
| Sales, Use and Withholding Taxes Return (Form 5080) Note: Square Payroll will only submit the Withholding section of this return. You are responsible for filing the Sales and Use Tax portions of Form 5080. | Monthly or Quarterly | |

Additional Information Regarding Form 5080 / 5081
Forms 5080 and 5081 are combined returns used to report sales tax, use tax, and income tax withholding. Square Payroll is only able to report the withholding section of this return as we do not have the necessary information to file the sales and use tax portions. You will need to file an additional Form 5080 / 5081 with the owed sales and use tax amounts. If sales and use tax are not owed, you can enter zeros for these amounts. Additionally, please leave the withholding tax portion of the form blank as Square Payroll will be filing this for you. The Michigan Department of Treasury will then be able to combine the form you filed with the one that Square Payroll filed on your behalf.
