How Connecticut taxes your paycheck
Connecticut uses a graduated rate schedule with 7 brackets for single filers in 2026. Like the federal system, only the income inside each bracket is taxed at that bracket's rate — moving into a higher bracket never taxes your whole paycheck at the higher rate.
On exemptions: Maximum personal exemption varies by filing status: MFS $12,000; single $15,000; HOH $19,000; MFJ $24,000. Reduced by $1,000 for each $1,000 of Connecticut AGI above the threshold; fully eliminated at MFS $35,000 / single $44,000 / HOH $56,000 / MFJ $71,000...
