Connecticut has one of the most complex income tax structures in the Northeast — 7 brackets from 2% to 6.99%, a $15,000 personal exemption, and a credit for NY taxes paid by commuters.
CT income tax starts at 2% and reaches 6.99% above $500,000 (single). The personal exemption is $15,000 (single) / $24,000 (married), but phases out entirely above $56,000 (single). No CT city charges a local income tax. CT gives a tax credit for income taxes paid to other states, including New York — key for Fairfield County commuters.
Connecticut is home to the highest concentration of hedge fund managers in the United States — Greenwich alone houses Bridgewater Associates, Point72, and dozens of other major funds. The result is a 6.99% top income tax rate that extracts substantial revenue from a small number of extremely high earners. For the typical Connecticut worker earning $75,000–$150,000, the effective state tax rate runs 5–6%, which is high for New England but lower than the 6.99% headline implies. The $15,000 personal exemption ($24,000 married) meaningfully reduces the base — though it phases out entirely above $56,000 for single filers, so most earners lose it before their income gets very high.
The New York commuter situation is one of the most misunderstood tax facts in Fairfield County. A Greenwich, Darien, or Westport resident who commutes to Manhattan pays New York income tax on their NYC wages — not Connecticut income tax on those wages. New York taxes income based on where it's earned. Connecticut then gives a tax credit for taxes paid to NY, which generally covers most or all of the CT tax liability on those same wages. In practice, most Fairfield County-to-Manhattan commuters effectively pay NY income tax rates on their job income, not CT rates. CT still taxes CT-source income (investment income, CT-based work) without the offset.
Connecticut's personal exemption phases out rapidly for higher earners. The $15,000 exemption (single) begins phasing out at $56,000 of CT adjusted gross income, reducing by $1,000 for each $1,000 of income above that. At $71,000, the exemption is completely gone. This means the effective tax rate starts rising faster than the bracket rates alone suggest for earners in the $56,000–$71,000 range. No Connecticut city or municipality adds a local income tax on wages — Hartford, New Haven, Bridgeport, and Stamford workers pay only the state rate.
Connecticut's property taxes are among the highest in the country, and the income tax burden compounds this. Hartford, Bridgeport, and Waterbury homeowners face mill rates above 40 (4%+ of assessed value annually). Greenwich homeowners pay lower rates because Greenwich's grand list is enormous, but the dollar amounts are still high on expensive homes. Workers relocating from high-tax states like California often find CT income taxes comparable but property taxes more variable — the answer depends heavily on which town you land in.
| Income (Single) | Income (Married) | Rate |
|---|---|---|
| $0 – $10,000 | $0 – $20,000 | 2% |
| $10,001 – $50,000 | $20,001 – $100,000 | 4.5% |
| $50,001 – $100,000 | $100,001 – $200,000 | 5.5% |
| $100,001 – $200,000 | $200,001 – $400,000 | 6% |
| $200,001 – $250,000 | $400,001 – $500,000 | 6.5% |
| $250,001 – $500,000 | $500,001 – $1,000,000 | 6.9% |
| Over $500,000 | Over $1,000,000 | 6.99% |
Personal exemption: $15,000 (single) / $24,000 (married). Exemption phases out above $56,000 (single) / $100,500 (married). Brackets apply to CT adjusted gross income after the personal exemption.

Connecticut has seven progressive income tax brackets in 2026: 2% up to $10,000, 4.5% from $10,001–$50,000, 5.5% from $50,001–$100,000, 6% from $100,001–$200,000, 6.5% from $200,001–$250,000, 6.9% from $250,001–$500,000, and 6.99% above $500,000 (for single filers). The personal exemption is $15,000 (single) / $24,000 (married), but phases out rapidly for incomes above $56,000 / $100,500.
CT workers pay: federal income tax, Connecticut state income tax (2%–6.99% progressive), Social Security (6.2% up to $184,500), and Medicare (1.45%). No Connecticut city or municipality adds a local income tax. Hartford, New Haven, Stamford, and Bridgeport workers pay only the CT state rate with no city surcharge added on top.
Your NYC wages are taxed by New York, where you earn them. Connecticut gives you a credit for taxes paid to NY on those wages — which generally prevents double taxation. For most Fairfield County commuters, the NY credit covers most CT state tax on their job income. You'll still owe CT tax on CT-source income (investment returns, any CT-based work), but the daily Manhattan wages are effectively paying NY rates, not CT rates.
Not for most retirees. Connecticut fully exempts Social Security benefits from state income tax if your federal adjusted gross income is below $75,000 (single) or $100,000 (married). Above those thresholds, the exemption phases out and Social Security may be partially taxable. High-income CT retirees with investment income and Social Security should verify their exposure with a tax professional.
Massachusetts has a flat 5% income tax (plus a 4% surtax on income above $1 million, making it effectively 9% for high earners). New York has a higher top rate (10.9% at very high incomes). For typical earners at $100,000–$200,000, Connecticut's 6% bracket is higher than Massachusetts's 5% flat rate but significantly lower than combined NY state + NYC rates (which can reach 14%+). CT's major competition for high earners is Florida and Texas at 0%.
On a $95,000 salary paid biweekly ($3,654 per check), CT withholds approximately $200–$215 per paycheck in state income tax. On $150,000 ($5,769 per check), it's approximately $335–$355. On $75,000 ($2,885 per check), approximately $145–$160. Most middle-income earners land in the 5.5%–6% bracket range, with effective CT tax rates of 5–6% after the personal exemption (when applicable).
Connecticut provides a personal exemption of $15,000 for single filers and $24,000 for married filing jointly. However, this exemption phases out for higher earners: once your CT adjusted gross income exceeds $56,000 (single) or $100,500 (married), the exemption decreases by $1,000 for every $1,000 of income above the threshold. It's completely eliminated at $71,000 (single) or $124,500 (married). For most typical earners, the exemption is either partially or fully phased out.
Yes. The One Big Beautiful Bill (2026) exempts overtime premiums and tip income from federal income tax only. Connecticut taxes those wages at the state level (2%–6.99% progressive brackets).
