CT  DOL  Employer Registration Number99-999-99 ( 7 digits)

  • Find an existing Employer Registration Number or apply online at the  DOL  after paying first wages and accumulating $1500  of  UIliability  to receive an Employer Registration number and  UI  tax rate immediately upon completion of the application.
  • Some CT employers may be "Reimbursable". This means the employer would be required to file subject wages, but do not pay unemployment insurance through payroll tax deductions. Instead, CT sends out monthly billings for the reimbursement of benefits paid. If an admin is "Reimbursable", they should check the box indicating so in their CT tax settings.

Required Payroll Documentation:

Withholding 

CT-941 ( Connecticut Quarterly Reconciliation of Withholding): This report is a good source of information used to balance wages and taxes withheld from prior quarters.
