Worked example
Single filer earning $60,000 in Connecticut, paid biweekly: federal tax is $5,020.00/yr (after the $16,100 standard deduction). Connecticut taxable income is $60,000 − the $15,000 personal exemption = $45,000.00, so state tax is $1,775.00/yr. Social Security is $3,720 and Medicare is $870. Take-home: $48,615.00/yr — $1,869.81 per biweekly paycheck. Change the salary above and try your own.
How Connecticut paycheck tax works
Federal first: your employer annualizes each paycheck. Federal taxable income is your gross minus the IRS standard deduction for 2026 — $16,100 if you file single, $32,200 married filing jointly (IRS Rev. Proc. 2025-32) — then taxed through the 2026 federal brackets (10% up to 22% across most middle incomes). Social Security takes 6.2% of wages up to the 2026 wage base of $184,500, and Medicare takes 1.45% of all wages (plus 0.9% over $200,000 single / $250,000 joint).
Connecticut tax uses its 2025 tables — the latest published when this page was built (the federal figures on this page are 2026): seven graduated rates from 2% to 6.99%. Connecticut gives a personal exemption of $15,000 single / $24,000 joint (it phases out at higher incomes). Connecticut also has a small personal tax credit (1%–30% of tax, income-dependent) and a high-income rate recapture that this simplified calculator does not model, so treat the Connecticut figure as a close estimate. This calculator annualizes your salary; your employer's per-paycheck withholding may differ slightly.

My real Connecticut paycheck is different. Why?
Pre-tax 401(k) or HSA contributions, health premiums, garnishments, bonuses (often withheld at a flat 22% federal), and your W-4 elections all move the real number. Many states also withhold a little differently per paycheck than this annualized estimate. Treat this as a close, honest estimate — not payroll software.
What about overtime or a bonus?
Overtime hours are taxed at the same rates — a higher paycheck just annualizes higher. Try our time and a half calculator and bonus tax calculator for those.
