The employer notification form UI-21A, ‘Notice to Employer of Claim Filed and Request for Information’, is the notice that an individual has filed for unemployment benefits and shows the potential liability your company or organization may have. This form is automatically generated by the ReEmployCT system. The form allows you to protest depending on the reason for separation. It also can help reduce fraud and non-fraud overpayments; Connecticut is among the states that notifies employers when unemployment applications charge to them. The 21A notice is one of the first lines of defense in combatting unemployment fraud.
As part of the eligibility process, when someone files their application for unemployment benefits, they must list their previous employers within a certain time period. The employer receives the notification by U.S. mail or email and, if they are signed up, through the SIDES system. If the employer is represented by a Third-Party Agent, the notice will go to the Third-Party Agent.
The employer should respond to the notice and confirm or protest the claim application. If protesting, please provide details of the separation. Employers may respond to notifications:
- Through the SIDES system, if they are signed up with SIDES;
- Through ReEmployCT QuickAccess;
- By fax: (866) 754-1410; or
- By mail:
