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