E-file requirement

 
Conn. Agencies Regs. Section 12-690-1 requires return preparers who prepared 50 or more Connecticut income tax returns to file all Connecticut personal income tax returns electronically using the Federal/State Electronic Filing Program (e-file).
 

Q&A FOR REQUIRED E-FILERS

Electronic filing offers the following benefits:

  • 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.
  • Taxpayers who electronically file their return receive refunds within a few days; compared to six - eight weeks for paper-filed returns.
  • 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.

To participate in e-file a tax practitioner must become an Electronic Return Originator.  Visit Electronic Filing Information for the Tax Professional for more details.

DRS understands electronic filing may be an adjustment for some taxpayers.  We hope preparers will focus on the positive promotion of electronic filing as an additional service offered to clients in addition to quality tax advice and preparation.   

If you have any questions about required filing, please contact the DRS Help Desk at 860-297-4713 or the IRS e-file Help Desk at 866-255-0654.
