Employers subject to Unemployment Insurance (UI) as well as employers not subject to UI must file employee wage records quarterly to DUA online.  

Employers not subject to UI must register their business with DUA before filing quarterly wage records to DUA.  When you register a new or successor business with DUA, you will receive an 8-digit Employer Account Number (EAN) that must be used for conducting all business with DUA.  You will also receive a notice with a UI Online User ID and Password.  You must activate your account before DUA can accept your wage records and contribution payments.
