How Connecticut taxes your income
Connecticut uses 7 progressive rates from 2% to 6.99%. Only the slice of income inside each band is taxed at that band's rate, so your effective state rate is lower than the top rate.
We subtract an estimated $15,000 (the state standard deduction plus any dollar-amount personal exemption) from your income before applying the Connecticut brackets.
Not modelled: personal tax credits, most income-based phase-outs, deductibility of federal tax where a state allows it, local income taxes (for example city or county taxes), and state payroll taxes such as disability or family-leave contributions.
Deduction phase-out modelled linearly (exemption 30,000 to 45,000 of income).
