A Guide To Connecticut Business Tax Credts

A Message from the Commissioner

Connecticut continues to offer a variety of business incentives as we work to renew our state economy. Therefore, the Department of Revenue Services (DRS) is pleased to provide a Guide to Connecticut Business Tax Credits as a comprehensive resource for the business community. In addition to describing available tax credits, this publication identifies legislative or policy changes that may impact your business. I hope you will find this information useful.

You may also find information and assistance through our website at portal.ct.gov/drs and our Taxpayer Service Center (TSC) located on the website. The DRS website allows visitors to download tax forms and publications as well as register to receive DRS E-News, which provides important email tax alerts directly to subscribers.

Our TSC enables businesses to file electronically and pay most tax obligations. Users can also maintain business accounts with DRS for payments of tax bills and to review previous electronically filed returns. For taxpayers unable to use online access, DRS Taxpayer Services personnel are available to provide assistance by telephone or in person at 450 Columbus Blvd., in Hartford from 8:30 a.m. to 4:30 p.m., Monday through Friday. Many tax questions can be also answered by using our automated phone system anytime. Call 1-800-382-9463 (Connecticut calls outside the Greater Hartford calling area only), or 860-297-5962 (from anywhere).

DRS will continue working hard to improve the way we do business and assist taxpayers. Please feel free to contact me with your comments at any time.
