HARTFORD — At Governor Lamont’s direction, Commissioner Mark D. Boughton announced March 18 that the Department of Revenue Services (DRS) is extending the filing and payment deadline for Connecticut individual income tax returns to Monday, May 17, 2021.

This extension aligns with the U.S. Department of the Treasury’s announcement Wednesday, where it indicated federal income tax filings and payments would be extended until May 17, 2021.

“Given the relatively late start to the federal income tax filing season and recent passage of the America Rescue Plan Act, which includes provisions that impact tax filing this year, yesterday’s announcement is understandable,” said Commissioner Boughton. “Taxpayers do an excellent job of filing their Connecticut income tax returns accurately and on time. To further assist and support them, Connecticut will align with the extended federal deadline.”

Commissioner Boughton added that since Connecticut’s individual income tax return begins with federal Adjusted Gross Income, it is often beneficial to complete one’s federal return first. Those with questions about their state taxes should contact the agency; DRS professionals are available to provide assistance.

File Electronically

The DRS highly recommends electronic filing, including via the DRS online Taxpayer Service Center, which is easy, secure, and free to use. Electronic filing, along with requesting direct deposit, is the fastest way to receive a refund, if one is expected.
