Mailing Addresses

Most Connecticut taxpayers can electronically file through the Taxpayer Service Center (TSC). The TSC is a free, fast, easy, and secure alternative to mailing paper.

The following are the mailing addresses to be used for paper returns that are available from DRS and included in the Connecticut income tax booklets. NOTE: If you are using a form generated from a software program, the form may have a different mailing address. Please use the address listed on the form you complete. By doing so, you will expedite the processing of your return.

Make your check or money order payable to: "Commissioner of Revenue Services". Please write the tax year and form name in the memo. (example: 2018 CT-1040)
