Connecticut Paycheck Calculator

See your real take-home pay in Connecticut after federal tax, CT state tax, FICA, 401(k), and health insurance.

Connecticut uses a progressive income tax, with marginal rates running from 2% on the first dollars of taxable income up to 6.99% at the top. Where your salary lands in those brackets — after the state's deduction and any pre-tax contributions — decides how much comes out of each check on top of federal tax and FICA. Run your numbers below to see the full federal-plus-Connecticut breakdown per paycheck and per year.

Connecticut tax notes

  • Connecticut uses a personal exemption that phases out with income instead of a standard deduction — not modeled here.
  • The lowest two rates were cut in 2024, the state's first rate reduction since the 1990s.
