7 tax brackets from 3% to 6.99%
At $100,000 income, Connecticut charges 6% marginal state income tax, resulting in approximately $4,655 in state tax burden. Connecticut has 7 progressive brackets from 3% to 6.99%, with the top rate applying to income over $500,000. CT offers proximity to NYC jobs with lower income tax than NY, but higher property taxes.
Connecticut has a progressive income tax system with rates ranging from 3% to 6.99% across 7 tax brackets. While the top rate is moderate compared to neighboring New York (10.9%) and Massachusetts (9%), Connecticut's overall tax burden ranks in the top 5 nationally when you include extremely high property taxes (average 1.96% - 2nd highest in US).
Why these rates? Connecticut is a wealthy state (highest per capita income in the US) with expensive local services, excellent public schools in affluent towns (Greenwich, Darien, New Canaan), and proximity to New York City. Many residents work in NYC but live in CT to avoid NYC's 3.876% city income tax on top of NY's 10.9% state rate.
How it compares:
Recent changes: Connecticut introduced its 7th bracket (6.99% over $500K) in 2015 to close budget deficits. In 2024-2026, the state has not reduced rates despite neighboring states cutting taxes, leading to concerns about wealth flight to Florida and Texas.

| State | Tax Rate | Tax on $100K Income | Difference from Connecticut |

Key insight: Moving from Connecticut to Florida saves $4,655/year at $100K income, $7,655/year at $150K. But property tax must be factored in.
The total picture:
Connecticut's income tax ranges from 3% to 6.99% across 7 progressive brackets. Most middle-income earners ($50K-$100K) pay an effective rate of 2.9-4.7%. The top 6.99% rate only applies to income over $500,000, making it less burdensome than neighboring New York (10.9% max). However, Connecticut's property tax (1.96% average) is 2nd highest nationally, which significantly impacts overall tax burden.
Connecticut has 7 tax brackets: 3% ($0-$10K), 5% ($10K-$50K), 5.5% ($50K-$100K), 6% ($100K-$200K), 6.5% ($200K-$250K), 6.9% ($250K-$500K), and 6.99% (over $500K). These are marginal rates - you only pay the higher rate on income within each bracket. For example, $150K income pays 6% only on the portion between $100K-$150K, not the entire $150K.
Yes, Connecticut has lower income tax than New York. At $100K income: CT charges $4,655 (6% max bracket), NY charges $6,203 (10.9% max bracket) - CT saves $1,548/year. NYC residents pay an additional 3.876% city tax. However, CT property tax is higher (1.96% vs NY 1.72%). For high earners living in Fairfield County and commuting to NYC, CT offers significant savings despite similar cost of living.
Connecticut is losing residents to lower-tax states, particularly Florida (0% income tax). Main reasons: (1) Extremely high property taxes ($11,760/year on $600K home vs $5,880 in FL), (2) Retirees seeking warmer weather and tax savings, (3) Young professionals priced out by high housing costs, (4) Businesses relocating to business-friendly states. CT lost 28,623 net residents (2021-2022 Census data), continuing a multi-year trend.
Move if: you work in NYC and earn $150K+ (saves $3,000-8,000/year vs living in NYC), want top public schools (Greenwich/Darien/Westport rank nationally), prefer suburban lifestyle with yard space, and can handle 45-90 minute Metro-North commute. Stay in NYC if: you value urban lifestyle, don't want car dependency, or earn under $100K (the income tax savings don't justify higher CT housing costs). Calculate property tax carefully - varies wildly by town.
