CT Taxes & Business Incentives

Connecticut offers a very competitive set of tax incentives and financing options to assist business. Connecticut's menu of options is by no means simple, but there are many programs that will help maximize your tax savings. Most importantly Connecticut is willing to work with any company bringing new jobs and investment to the state to create a tax incentive plan that works for them. In addition to statutory tax incentives the Governor and Department of Economic & Community Development have the ability to give non-statutory incentives to assist companies.

Listed below are taxes that apply to Connecticut businesses and the incentives that can be applied against each of these taxes based on business type.  Most credits require state notification and qualification. For more information visit www.ct.gov/drs
