How Connecticut taxes a paycheck
Connecticut's seven brackets run from 2% on the first $10,000 of taxable income to 6.99% above $500,000 for a single filer, with married thresholds doubled. The 2024 budget cut the two lowest rates, from 3% to 2% and from 5% to 4.5%, the first rate reduction since the tax was created in 1991. The 5.5% bracket starts at $50,000 and 6% at $100,000, which is where most salaries end up.
Instead of a standard deduction Connecticut has a personal exemption of $15,000 single and $24,000 married, but it phases out fast: by $1,000 for every $1,000 of income above $30,000 (single) or $48,000 (married), reaching zero at $45,000 and $72,000. The calculator applies that phase-out, so a $60,000 single filer gets no exemption at all. Below those thresholds Connecticut also offers personal tax credits of 1% to 75% of tax; they are not modelled.
Two other Connecticut mechanisms are omitted: the phase-out of the 2% bracket for single filers above $56,500 of AGI, and the tax benefit recapture that adds up to $3,150 for filers above $105,000. Both increase tax for middle and higher earners, so estimates at those incomes run slightly low. Connecticut Paid Leave takes a further 0.5% of wages up to the Social Security wage base and is a separate line.
How much taxes are taken out of paychecks in Connecticut?
On a $60,000 salary in 2026, a single filer in Connecticut pays about $5,020 in federal income tax, $4,590 in Social Security and Medicare, and about $2,550 in Connecticut income tax, leaving roughly $47,840 a year or $1,840 every two weeks. Paid Leave would take a further $300. The state share is about 4.3% of gross.
No Connecticut town or city levies an income tax; the state's 169 municipalities rely on property tax, which is among the highest in the country and is the tax residents notice most.
Connecticut compared with its neighbours
Connecticut sits between New York (3.9% to 10.9%, plus New York City's tax), Massachusetts (a flat 5%, 9% above $1.08 million) and Rhode Island (3.75% to 5.99%). On a $60,000 single salary the state tax is about $2,550 in Connecticut, $2,780 in Massachusetts, $2,640 in New York and $1,630 in Rhode Island.
The Massachusetts comparison drives a lot of cross-border commuting decisions. Massachusetts's flat 5% with a $4,400 exemption and Connecticut's graduated schedule with no deduction at $60,000 land within a few hundred dollars; Connecticut pulls ahead above about $100,000, where its 6% and 6.5% brackets exceed Massachusetts's 5%.
Withholding forms and filing status in Connecticut
Connecticut employers withhold from Form CT-W4, on which employees pick a withholding code (A through F) that stands in for filing status and expected income; the codes exist because Connecticut's phase-outs make a simple rate impossible to apply per paycheck. Married couples filing jointly get doubled bracket thresholds and a $24,000 exemption that phases out from $48,000 of income, so a one-earner couple on $60,000 keeps most of the exemption while a single earner on the same salary gets none.
Connecticut has no reciprocal agreements and taxes non-residents on Connecticut-source wages, with a convenience-of-the-employer rule that applies only to residents of states that impose one on Connecticut residents (in practice New York). A Connecticut resident who works in New York pays New York tax and takes a credit on the Connecticut return.
