Program overview

Rhode Island offers a headline rate that ranks among the highest of any state, applied to the increase in qualified research expenses conducted in Rhode Island over a base amount, with a reduced rate on spending above a threshold. The credit is non-refundable and limited to a share of liability in any given year, but the extended carryforward means credits are rarely wasted. Rhode Island also offers a separate credit for qualified research and development property.
