All wages paid under one 10-digit UIA Employer Account Number must be reported on the same Form UIA 1017, Wage Detail Report. We can post and store in our data base only one Wage Detail Report for each quarter reported under each 10-digit UIA Employer Account Number. If you have multi-unit numbers greater than 000 for your different locations and/or salaried and hourly payroll, then each multi-unit number should be reported on a separate Form UIA 1017. If you wish to request multi-unit numbers, submit a letter stating the different locations (complete addresses) and a description of the principal business or activity being conducted at each site. You may also use Schedule C found in your Form 518, Michigan Business Taxes Registration Booklet. Requests should be mailed to:
