Connecticut Takes a Different Tax Path Than the Federal Government

Connecticut isn't following the federal government's lead on business tax breaks anymore. Starting in 2026, companies in the state won't be able to deduct research and experimental expenses as quickly as the federal rules allow. This move is part of a new state law that separates Connecticut's tax system from federal changes passed in 2022. The state is also giving businesses more time to adjust. Instead of instantly adopting new federal rules, Connecticut will wait until 2026 to align with them. This delay is a big shift—it means business taxes won’t reflect those federal changes for expenses made between 2022 and 2025. The law also introduces a new tax credit for small businesses that invest in research and development within Connecticut. This could help local startups and smaller companies compete with bigger players.But why make these changes? Some argue that Connecticut’s tax system was becoming too tied to federal rules, which can fluctuate with political shifts in Washington. By decoupling, the state gains more control over its own tax policies. Others worry that this could make life harder for businesses that rely on those federal deductions. Either way, Connecticut is betting that this move will help balance its budget while still encouraging innovation.
