Connecticut Internet Tax and Wage System

By state statute, registered employers must file and pay their UI tax and wage returns via electronic means unless granted a waiver. This includes both taxable employers who file the Employer Contribution Return and Employee Quarterly Earnings Report (Forms UC-2 / UC-5A) and reimbursable employers who file the Employer Wage and Research Information Report and Employee Quarterly Earnings Report (Forms UC-2R / UC-5R).  

To file an original return, please follow this link: Tax and Wage Reporting

At the present time any correction returns must be filed on paper.  The form is available at

Name, Address and Status Changes 

It is important to keep your name and address up-to-date, if for no other reason than you will get your  tax forms on time insuring that you can avoid being charged otherwise unnecessary penalties and fees.

You will want to insure that we have the correct FEIN for you as well.  The Federal government uses it to corroborate that you have paid your State UI taxes in a timely fashion.  This allows you to take a credit on your FUTA taxes. 

If you have acquired a business or sold a business or are out of business you should report that as soon as possible so that your experience rating records can be adjusted as required.  You can report those changes here too.

Electronic Funds Transfer (EFT)

Taxable employers may pay their UI taxes for any quarter at any time.   This can be done independently of filing a tax and wage return.  In order to safeguard it, your banking information is fully encrypted - both while stored and while in transmission.
