Connecticut Paycheck Calculator
Seven brackets from 2% to 6.99% with no standard deduction, and a 2% bracket that phases out as income rises.
Connecticut has seven brackets from 2% to 6.99% and no standard deduction. The 2% bracket shrinks as income rises and is gone for single filers once Connecticut AGI passes $101,500, so most of a middle-income paycheck is taxed at 4.5% and 5.5%.

Connecticut Paycheck FAQ
Common questions about paychecks and taxes in Connecticut
What is the Connecticut state income tax rate?
Seven brackets for single filers: 2% on the first $10,000, 4.5% to $50,000, 5.5% to $100,000, 6% to $200,000, 6.5% to $250,000, 6.9% to $500,000 and 6.99% above. Joint filers' brackets are twice as wide, and heads of household's 2% bracket runs to $16,000. These are the 2026 rates on the Department of Revenue Services' Form CT-1040ES.
Does Connecticut have a standard deduction?
No. Connecticut has a personal exemption instead, up to $15,000 single and $24,000 joint, but it phases out completely once Connecticut AGI reaches $44,000 single, $71,000 joint, $35,000 married filing separately or $56,000 head of household. The calculator doesn't apply it, so it overstates tax below those incomes.
How does Connecticut's 2% bracket phase-out work?
Once Connecticut AGI passes $56,500 (single), $50,250 (married filing separately), $100,500 (joint) or $78,500 (head of household), the 2% bracket shrinks and the freed income is taxed at 4.5% instead. Single filers lose the whole bracket above $101,500. The calculator uses the phase-out as it stands at $104,000 of income, so it's exact near that income but overstates tax for lower incomes (by up to $250 for a single filer) and understates it for higher joint and head-of-household incomes.
What else does this calculator leave out for Connecticut?
Connecticut's personal exemption, personal tax credit and recapture all depend on income, and the calculator uses each as it stands at $104,000 of income, where all three are zero, for every income. Lower earners get the credit, worth a share of their tax, until $64,500 of AGI (single) or $100,500 (joint), so they see too much tax: for a single filer earning $25,000 to $30,000 the exemption and the 2% bracket alone account for $925 a year, and the credit adds more. Higher earners pay the recapture on top of the bracket tax, starting above $105,000 of Connecticut AGI (single), $210,000 (joint) or $168,000 (head of household), so they see too little, by up to $3,400 a year single, $6,800 joint and $5,320 head of household.
