Connecticut's Official 
Logging into the TSC-IND
Most residents and nonresidents are eligible to file online through the TSC-IND. Here is information for
First-Time User? New to the TSC? If you have not used the TSC before:
-
You can enter your social security number and a prior year's federal adjusted gross income if you filed a Connecticut income tax return for the prior year. Click here for more information.
-
If you have never filed a Connecticut income tax return before, you may still be able to file through the TSC. Click here for information for first-time filers.
If you experience problems and you get "locked out" of the TSC-IND, please call Taxpayer Services during business hours.
Returning TSC User? If you used the TSC before: If you used the TSC before to file a return, you already created a password. After you enter your Social Security Number (or if a joint account, enter the primary filer's password), you will be taken to the password entry screen. If you don't know your password, click "Forgot Passord?" and answer the 2 security questions.
If you still cannot access the TSC, you may submit a written request for your password to be reset by completing TPG-196, Individual Password Reset Request. Mail or fax the completed form to the address or fax number listed on the form. For security reasons, DRS CANNOT reset your password unless you submit the completed form.
