Connecticut State Income Tax Guide (2026)
Connecticut applies progressive income tax rates from 3.0% to 6.99%, and like California, does not recognize HSAs for state tax purposes.
1. Connecticut Progressive Tax Brackets
Connecticut uses progressive tax brackets, meaning higher portions of your income are taxed at higher rates - up to a top marginal rate of 6.99%. You only pay the higher rate on the dollars that fall within each bracket, not on your entire salary.
| CT Taxable Income (Single) | Marginal Rate |
|---|---|
| $0 to $10,000 | 3% |
| $10,001 to $50,000 | 5% |
| $50,001 to $100,000 | 5.5% |
| $100,001 to $200,000 | 6% |
| $200,001 to $250,000 | 6.5% |
| $250,001 to $500,000 | 6.9% |
| $500,001 and over | 6.99% |
2. Deductions and Conformance
Connecticut grants a personal exemption of $15,000 per filer rather than a standard deduction. Pre-tax 401(k) contributions and employer health premiums reduce your Connecticut taxable income. However, HSA contributions are not deductible at the CT state level and are taxed when earned.
3. Local Income Taxes
Connecticut does not conform to federal HSA tax treatment, so HSA contributions are subject to state income tax.
Compare With Other Progressive-Tax States
Connecticut uses a progressive income tax system. Compare net pay across all progressive tax states: California, New York, Massachusetts, New Jersey, Virginia, Maryland, Ohio.
