Calculate your income tax in Connecticut

Calculating your Connecticut state income tax is similar to the steps we listed on our Federal income tax calculator:

  1. Determine your filing status
  2. Work out your adjusted gross income [Gross income − Retirement contributions = Adjusted gross income]
  3. Calculate your state taxable income [Adjusted gross income − (Itemized deductions + Exemptions) = State taxable income]
  4. Figure out your state/local tax liability [State taxable income × State tax rate = State tax liability]
  5. Deduce your state payroll tax liability [Gross income × State payroll tax rate = State payroll tax liability]
  6. Add up all state and local taxes [State tax liability + State payroll tax liability = Total state income taxes]
