|---|---|---|
| 2% | $0 | $10,000 |
| 4.5% | $10,000 | $50,000 |

Common questions
- What are Connecticut income tax brackets for 2026?
- Connecticut has 7 brackets for single filers, starting at 2% and reaching 6.99% at the top. The full table is listed above, with the standard deduction subtracted before those rates apply.
- What is the top Connecticut income tax rate?
- The top Connecticut rate is 6.99%, and it only applies to income above the highest bracket threshold shown above — not to your whole salary. The rate on your first dollars is 2%.
- What is the Connecticut standard deduction for 2026?
- $15,000 for single filers and $24,000 for married couples filing jointly; there is no separate dependent exemption. Taxable income is what remains after that deduction, and it is what the brackets are applied to.
- What is the take-home pay on $100,000 in Connecticut?
- For a single filer paid biweekly with no 401(k) deferral and no health premiums, a $100,000 salary in Connecticut leaves $2,894.42 per paycheck — $75,255.00 a year, an effective rate of 24.7% after $13,170 of federal income tax, $3,925 of Connecticut tax and $7,650 of FICA.
- Do remote workers pay Connecticut income tax?
- A Connecticut resident is generally taxed by Connecticut on wages earned anywhere, including wages for a remote job whose employer sits in another state. Days worked physically outside Connecticut can matter in some cases, and a non-resident working in Connecticut is generally taxed on income earned here. Nothing here is tax advice — the details depend on your situation.
- Does Connecticut have local income taxes?
- Connecticut has no broad statewide local income tax layered on top of the state rate that this calculator models. School, county, city or occupational taxes can still apply in particular places, and the calculator does not model them.
