Frequently Asked Questions

Filing Options for Individuals Who Cannot File through the TSC
We are sorry, but you cannot use the Taxpayer Service Center (TSC) to file your Connecticut income tax return this year. However, you may still file electronically using the fed/state efile program through a tax preparer or using online software. Visit our Electronic Filing page for more information. 
What are the benefits to you of electronic filing?
  • Allows the Department of Revenue Service (DRS) to process returns quickly and accurately, saving tax dollars.
  • Taxpayers who have a return with a balance due can file early and can choose to pay the tax due anytime on or before April 15.
  • Electronically filed returns receive an acknowledgement of receipt from the Internal Revenue Service (IRS) and the State of Connecticut and are verified to be mathematically correct, eliminating data entry errors and lost or misplaced mail.
You may also file your return on paper.  Go to our Income Tax Forms Page to download the forms.
