How Connecticut taxes your paycheck in 2026
Connecticut uses graduated marginal brackets for 2026 - 2% to 6.99% (7 brackets) for single filers. You pay each rate only on the income that falls inside that bracket, after subtracting the personal exemption of up to $15,000 (it phases out as income rises). On a $60,000 salary with 5% to a pre-tax 401(k), 2026 Connecticut income tax works out to about $2,385.00 for a single filer.

Federal taxes are the same in every state
Wherever you live, 2026 federal income tax uses the same brackets (10% to 37%, after the standard deduction for your filing status - $16,100 for single filers), the same federal Child Tax Credit, and the same FICA rules: 6.2% Social Security on wages up to $184,500, plus 1.45% Medicare on all wages and an extra 0.9% above $200,000 ($250,000 for joint filers). State tax is what makes a Connecticut paycheck different from one across the state line.
What this estimate leaves out
Worked examples on this page use the calculator's defaults: a single filer with no dependents taking the standard deduction for 2026. The calculator itself also supports married filing jointly, head of household and children under 17, including the federal Child Tax Credit and Connecticut's dependent breaks where they apply. Connecticut's new child tax credit (up to $150 per child for up to three children, starting in 2026) is not included in this estimate. Connecticut phases out the benefit of its lowest bracket above about $56,500 of income, applies a recapture at high incomes, and offers a small personal tax credit at moderate incomes - refinements not included in this estimate. Health insurance premiums, HSA contributions, itemized deductions and other credits are not modeled.
