Tax Computation Summary
How to Use This Connecticut Income Tax Calculator
Enter your Connecticut AGI (approximately equal to federal AGI with minor CT modifications) and select your filing status. If you paid property or vehicle taxes in Connecticut, enter the amount — you receive a dollar-for-dollar credit up to $300. High earners should note the recapture provision that phased out lower bracket benefits above $200,000 (single).
The Formula
CT Personal Tax Credit = $15 per exemption (phases out for high earners)
CT Property Tax Credit = min($300, property/vehicle taxes paid)
CT Recapture = additional tax for incomes above $200K (single)/$400K (MFJ)
CT Net Tax = CT Bracket Tax + Recapture − Property Credit − Personal Credit
Example
3% on $10,000 = $300 | 5% on $40,000 = $2,000 | 5.5% on $40,000 = $2,200
CT tax (before credits): $4,500
Property tax credit: $300 (if property taxes paid)
CT net state tax: $4,200
CT effective rate: 4.67% | CT marginal rate: 5.5%
