Offers Connecticut businesses tax credits or cash support for qualifying innovation activity.

Eligibility · United States · US-CT

Connecticut administers a bifurcated R&D tax credit system through the Department of Revenue Services (DRS) under two statutes: the Incremental Research and Experimental Expenditures Credit (Conn. Gen. Stat. §12-217j) and the Non-Incremental Research and Development Expenditures Credit (Conn. Gen. Stat. §12-217n). Both credits require qualifying research activity to be conducted within Connecticut and are claimed against the Connecticut Corporation Business Tax on an annual return. A distinguishing feature of the Connecticut system is a partial cash exchange mechanism: companies with gross income below approximately $70 million that hold unused, non-refundable R&D credit balances may exchange a portion of those credits for cash at a discounted rate, effectively converting a tax attribute into liquidity. This cash-exchange element has attracted particular interest from pre-revenue or tax-loss biotechnology and manufacturing companies that generate R&D credits they cannot immediately consume.

Eligibility is limited to for-profit corporations filing Connecticut corporate income tax returns with qualifying in-state R&D expenditures; universities and research institutions may participate in limited circumstances. The program is not sector-restricted by statute, but in practice the credit is most relevant to life sciences, advanced manufacturing, aerospace, and software companies with material Connecticut R&D payrolls. As of April 2026, the Connecticut legislature was considering a $25 million expansion of the R&D tax credit program, signaling continued policy support. Award values range from modest amounts for small companies to over $1.5 million for larger R&D operations, with the cash-exchange component subject to per-program annual availability.

Because the credit is claimed on the annual corporation tax return — not via a separate grant application — there are no competitive rounds or merit-based reviews. The primary execution challenge is QRE documentation under Connecticut's standards, which track closely with federal IRC §41 definitions. Companies in Connecticut with consistent R&D expenditure should model credit values under both the incremental and non-incremental pathways and assess eligibility for the cash exchange program based on gross income thresholds and unused credit balances.
