Posted: January 26, 2021
Last Update: February 16, 2021


When does the DRS individual income tax filing season begin this year?

The DRS Taxpayer Service Center (see 'TSC-Individual Login') began accepting online individual income tax returns beginning the week of Monday, January 18th, 2021.


What is the best way to file my Connecticut income tax return?
DRS strongly recommends electronic filing. The DRS Taxpayer Service Center is an easy, secure, and free option, and electronic filing is the quickest way to get your state refund if you are expecting one. Because Connecticut's individual income tax return begins with federal adjusted gross income, it is often beneficial to file your federal income tax return first.

When will the Internal Revenue Service (IRS) begin accepting federal income tax returns?
The IRS announced it will open their federal tax filing season on Friday, February 12th, 2021.

Where can I find Connecticut individual income tax forms and instructions?
Visit the DRS website here. While paper forms may be helpful in preparing your return, DRS highly recommends electronic filing when you are ready to file.

What is the best way to contact DRS if I have a question about state taxes or my state income tax return?

Taxpayers may also email DRS at DRS@po.state.ct.us.
