It depends on what state you reside in.
Connecticut offers a significant credit (25% or 40%, depending on the type of business). You need to file Form CT-IT (from the Connecticut Department of Revenue Services). Using the information on the voucher that you receive from Connecticut Innovations (the state’s venture capital arm), you (or your tax preparer) complete the CT-IT form.
