DRS: TSC Business Help Page

TSC Business Help Page

Connecticut business taxpayers can electronically file most Connecticut business tax returns using the Taxpayer Service Center (TSC-BUS). The TSC is an interactive tool that provides a free, fast, easy, and secure way to conduct business with DRS.

Some of the features of the TSC include the ability to:

  • view current balances,
  • schedule payments with tax returns,
  • make bill payments, and
  • amend certain business tax returns. 
Using our FAQs, you can easily get answers to the most frequently asked questions and you can also exchange confidential information with DRS through a "secure" mailbox.
Download the TSC Electronic Filing Flyer and keep it beside your computer for additional help in using the TSC-BUS.  This flyer provides information about:
    • logging on to the TSC
    • filing returns
    • making business tax payment-only transactions (including bill payments)
