How Connecticut Taxes Your Income
- Seven brackets. For single filers: 2% to $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.
- No standard deduction. A $15,000 personal exemption exists but phases out between $30,000 and $40,000 of income.
- Benefits recapture. Higher earners face phase-outs of the bottom brackets, creating hidden marginal-rate spikes between $200,000 and $400,000.
- No local income tax. Cities do not tax wages.

Estimated Tax Breakdown
Paid Family and Medical Leave
Connecticut employees contribute 0.5% of wages to the state's Paid Family and Medical Leave program. This is withheld on top of income tax and is not included in the calculator estimates above.
Retirement and Social Security
Social Security benefits are exempt for single filers with adjusted gross income below $75,000 ($100,000 for joint filers). Above those thresholds, a portion becomes taxable. Private pensions and IRA/401(k) withdrawals are taxed at ordinary rates.
