Connecticut state income tax details (2026)
Connecticut uses a progressive income tax — higher income is taxed at higher rates. These are the 2026 Connecticut brackets for single filers, applied after the state's deductions and exemptions:
| Connecticut taxable income | Rate |
|---|---|
| $0 – $10,000 | 2% |
| $10,000 – $50,000 | 4.5% |
| $50,000 – $100,000 | 5.5% |
| $100,000 – $200,000 | 6% |
| $200,000 – $250,000 | 6.5% |
| $250,000 – $500,000 | 6.9% |
| Over $500,000 | 6.9% |
Because the brackets are marginal, only the income inside each band is taxed at that band's rate. The calculator above applies this exact table to your annualized income and divides the result by your pay periods.
Connecticut vs. New York: state tax on a $75,000 salary

Federal income tax withholding (2026)
Federal income tax withholding is calculated using the annualization method from IRS Publication 15-T. Your per-period gross pay is annualized, reduced by the standard deduction ($16,100 single / $32,200 married / $24,150 head of household in 2026), and then taxed at the applicable bracket rates. The resulting annual tax is divided by your number of pay periods.
2026 federal tax brackets
| Taxable Income (Single) | Rate |
|---|---|
| $0 – $12,400 | 10% |
| $12,400 – $50,400 | 12% |
| $50,400 – $105,700 | 22% |
| $105,700 – $201,775 | 24% |
| $201,775 – $256,225 | 32% |
| $256,225 – $640,600 | 35% |
| Over $640,600 | 37% |
FICA: Social Security & Medicare
FICA taxes are the same in every state. Social Security is withheld at 6.2% on wages up to $184,500 (2026 wage base). Once your wages reach that cap in a calendar year, Social Security withholding stops. Medicare is withheld at 1.45% with no wage cap. An additional 0.9% applies to wages above $200,000 (single) or $250,000 (married).
Pre-tax deductions and your paycheck
Traditional 401(k) contributions and employer-sponsored health insurance premiums (Section 125/cafeteria plan) reduce your federal and state taxable income, lowering your income tax withholding. However, 401(k) contributions do not reduce FICA (Social Security and Medicare) wages. Health insurance premiums under a Section 125 plan do reduce FICA wages. Use the "Show deductions" section above to model your specific situation.
Frequently asked questions
- A single filer earning $65,000 in Connecticut takes home approximately $52,408 per year in 2026 — about $4,367 per month, or $2,015.67 per biweekly paycheck. That reflects $5,620 in federal income tax, $4,973 in FICA (Social Security and Medicare), and $2,000 in Connecticut state income tax. Pre-tax deductions like a 401(k) or health insurance would change these numbers.
- Connecticut has a progressive state income tax — the rate rises with income. A single filer pays roughly $1,325 in Connecticut tax on a $50,000 salary, $2,550 on $75,000, and $3,925 on $100,000. Use the calculator above for your exact withholding based on salary and filing status.
- Connecticut does not have a statewide local income tax layer. Your paycheck deductions consist of federal income tax, Social Security, Medicare, and Connecticut state income tax — no additional local income taxes are withheld at the state level.
- Start with your gross pay per paycheck. Subtract: (1) federal income tax based on your filing status and 2026 brackets; (2) Social Security at 6.2% up to the $184,500 wage base; (3) Medicare at 1.45%; (4) Connecticut state income tax. Any pre-tax deductions like 401(k) or health insurance reduce your taxable income further. The calculator above does this math instantly.
- Connecticut's treatment of Social Security retirement benefits varies by income level. Check the Connecticut Department of Revenue for the current exemption thresholds. This calculator estimates withholding on wages — Social Security benefit taxation is a separate determination made on your annual return.
- Connecticut does not require additional state payroll contributions beyond state income tax withholding. Some states (notably California, New Jersey, and New York) require workers to contribute to state disability insurance (SDI) or paid family leave (PFL) programs — Connecticut is not one of them.
