Connecticut has a progressive system with rates from 2% to 6.99%, plus a 3% income tax surcharge on certain high earners. The state also imposes local property taxes that are among the highest in the nation. Connecticut does not have local income taxes, but the combination of state income tax, property tax, and sales tax creates a significant overall tax burden.
Regardless of state taxes, all Connecticut workers pay federal income tax using the 2026 brackets: 10% on the first $11,925 of taxable income (single), 12% up to $48,475, 22% up to $103,350, 24% up to $197,300, 32% up to $250,525, 35% up to $626,350, and 37% on income above that. The standard deduction is $15,000 for single filers and $30,000 for married filing jointly in 2026.
All workers in Connecticut pay Social Security tax at 6.2% on wages up to $176,100 (2026) and Medicare tax at 1.45% on all wages. An additional 0.9% Medicare surtax applies to wages over $200,000 for single filers. These federal payroll taxes apply uniformly regardless of which state you live in.
Pre-tax deductions reduce your taxable income for both federal and state purposes. Contributing to a 401(k) (up to $24,500 in 2026, plus $8,000 catch-up if 50+) lowers both your federal and CT state tax bill. Health Savings Account (HSA) contributions ($4,300 individual, $8,550 family in 2026) are also pre-tax. Review your W-4 withholding: if you receive a large refund each year, you may be overwithholding, which means less money in each paycheck. The Tax Bracket Calculator shows your federal marginal and effective rates.
Connecticut has one of the higher state income tax burdens in the country, with rates from 2% to 6.99%. The Fairfield County corridor offers some of the highest salaries in the Northeast (driven by finance and insurance), but property taxes are also among the nation's highest. Many Connecticut workers commute to New York City and face dual-state tax obligations.
Connecticut's proximity to New York City creates a unique dynamic: many residents earn high NYC-area salaries but pay Connecticut's lower income tax instead of New York's. The trade-off is long commutes and some of the highest property taxes in the country. Weigh total cost, not just income tax, when comparing.
