Summary
On $75,000 gross income, you owe an estimated $3,475 in Connecticut state taxes for 2025.
Connecticut has 3 progressive brackets from 2.00% to 5.50% for 2025. The lowest rates were reduced from 3%/5% to 2%/4.5% starting in 2024.
Connecticut has no standard deduction. Instead, it offers a personal tax credit for lower-income filers, but your CT AGI of $75,000 exceeds the credit threshold.
Connecticut's recapture provisions add $100 to your tax ($100 low-bracket phase-out). These provisions phase out the benefit of lower brackets for higher earners.
Your top Connecticut bracket is 5.50%, but progressive taxation means your effective rate is 4.63% — lower than your marginal rate.
