How to Find New Mexico Reporting Unit Numbers
New Mexico employers must assign a Reporting Unit Number to each employee when adding them to Square Payroll. This is required because the New Mexico Department of Workforce Solutions requires us to include each employee’s Reporting Unit Number in the unemployment insurance (UI) tax filing (Form ES-903A) due each quarter.
You can find all active Reporting Unit Numbers for your business online:
Click Account Maintenance.
Click Maintain Employer Reporting Units.
On the next page, you will see a list of Active Reporting Units. If you only have 1 Reporting Unit Number for your entire company, you should use that Reporting Unit Number for all your employees.
If you’re unable to locate this, please contact the New Mexico Department of Workforce Solutions directly at 877-664-6984.
