Connecticut has no simple percentage method. Employers follow a 16-step formula built around your CT-W4 withholding code: a personal exemption that shrinks as pay rises, a credit that phases out, and add-backs that take away the low brackets for higher earners. Rates run from 2% to 6.99%, and every paycheck also has a 0.5% CT Paid Leave deduction.

2026 tax year, rules last verified November 12, 2026. An estimate, not tax advice. How we calculate
Each extra dollar you earn loses about 30¢ to taxes, but across all your pay the average is 20¢. A raise never lowers your take-home: only the dollars above a bracket line pay the higher rate.
| Annual pay | Effective | Marginal |
|---|---|---|
| $15,000 | 8.2% | 8.6% |
| $30,000 | 14.1% | 27.8% |
| $45,000 | 18.9% | 24.2% |
| $60,000 | 20.4% | 30.4% |
| $75,000 | 23.0% | 35.6% |
| $90,000 | 25.2% | 35.6% |
| $105,000 | 26.8% | 36.1% |
| $120,000 | 28.0% | 36.1% |
| $135,000 | 29.2% | 38.1% |
| $150,000 | 30.1% | 38.1% |
Same pay, W-4 and benefits; each state’s default withholding answers, no local taxes. Take-home per week:
Your employer annualizes the paycheck, subtracts the personal exemption for your code from Table A, and applies the rate schedule (Code B and C brackets are wider than Code A, D and F).
Two adjustments then claw back benefits at higher pay: a 2% phase-out add-back (Table C) and a recapture amount (Table D) that effectively taxes more of your income at the top rate. Finally a personal tax credit (Table E) of up to 75% for low incomes, shrinking to nothing, is applied. The annual result is divided by your number of paychecks.
Code D skips the exemption and credit for people with significant other income. Code E means no withholding.
Bonuses have no flat state rate: Connecticut figures tax on regular pay plus the bonus and withholds the difference.
| Annual taxable income | Tax |
|---|---|
| $0 – $10,000 | $0 + 2% |
| $10,000 – $50,000 | $200 + 4.5% |
| $50,000 – $100,000 | $2,000 + 5.5% |
| $100,000 – $200,000 | $4,750 + 6% |
| $200,000 – $250,000 | $10,750 + 6.5% |
| $250,000 – $500,000 | $14,000 + 6.9% |
| Over $500,000 | $31,250 + 6.99% |
Code B brackets are 1.6 times as wide and Code C brackets twice as wide. The phase-out add-back, recapture and personal tax credit are applied after this step.

None. No Connecticut city or town taxes wages.
CT Paid Leave is the only employee payroll deduction.
Connecticut has no reciprocal agreements. Nonresidents who work partly in Connecticut can file Form CT-W4NA so only the Connecticut share is withheld. Residents of states with a "convenience of the employer" rule, such as New York, are treated the same way when they work for a Connecticut employer.
Code F (single): $36.52. Code A: $40.65. Code C (married, spouse not working): $16.27. CT Paid Leave adds $5.00.
Use the chart on the CT-W4 for the filing status you expect on your Connecticut return. Most single people choose F, heads of household B, and married couples A, C or D depending on whether both work and on combined income.
It funds Connecticut’s paid family and medical leave program: 0.5% of your wages, up to $922.50 in 2026. Your employer can’t opt you out.
Connecticut phases out the personal exemption, the low-bracket benefit and the personal tax credit as annualized pay rises. Crossing one of those steps can raise withholding by more than the raise alone suggests.
