(Hartford, CT) – The Connecticut Department of Revenue Services (DRS) is reminding taxpayers that the deadline to file Connecticut personal income tax returns and make payments for the 2020 tax year is Monday, May 17th, 2021.

"While many taxpayers have already filed their 2020 income tax returns, the professionals at DRS will continue to offer the highest-quality customer service up to, and through, the May 17th extended deadline," said Revenue Services Commissioner Mark D. Boughton. "Those who file and pay the full amount of tax due on or before May 17th, 2021, will not be subject to any penalties or interest for not paying their state income taxes by the due date. As always, we strongly encourage electronic filing, and urge taxpayers to call DRS with their tax questions – we are here to help."

For those yet to file their Connecticut returns and make payments due May 17th, Commissioner Boughton offered the following reminders:

  • To further assist taxpayers, DRS is offering extended business hours for phone coverage until 6:00 p.m. on Monday, May 17th.
  • Taxpayers who are experiencing financial difficulties in paying the amount due are encouraged to contact DRS. We will work with taxpayers to assist them in understanding their tax liabilities and in making payment arrangements.
  • Taxpayers who need additional time to file beyond the May 17th deadline can request an extension of time to file until October 15, 2021, by filing Form CT-1040EXT, Application for Extension of Time to File Connecticut Income Tax Return for Individuals by May 17th.
