How It Works
Connecticut's progressive income tax applies marginal rates to each income bracket. The state also has a unique "tax recapture" provision that phases out the benefit of lower brackets for high-income taxpayers, which can push effective rates above the stated top marginal rate for some earners.
Connecticut exempts Social Security benefits from taxation for taxpayers below certain income thresholds. The state sales tax rate is 6.35%, and property taxes in Connecticut are among the highest in the nation.
