Connecticut Paycheck Calculator
Figure basis: Official Connecticut Department of Revenue ServicesThis Connecticut paycheck calculator estimates your take-home pay after the taxes withheld from a typical wage. Enter your gross pay, choose how often you are paid (weekly, every two weeks, twice a month or monthly) and select your filing status to see a full breakdown of every deduction and your net pay. The estimate combines four withholdings: federal income tax, calculated with the 2026 Internal Revenue Service annualised percentage method; Social Security at 6.2% up to the 2026 wage base of $184,500.00; Medicare at 1.45% on all wages; and Connecticut state income tax withholding, applied with the brackets published by the Connecticut Department of Revenue Services for tax year 2026. Results update as you type and the page link captures your inputs so you can save or share a calculation. This estimate covers federal withholding, FICA and state income tax only; State Disability Insurance where a state levies it, and any city or county local income tax, are not included and are noted separately. Use it to check a payslip, compare an offer, or plan a pre-tax contribution.
A $5,000 biweekly paycheck (single filer) in Connecticut is about $3,633.51 take-home, after federal income tax $766.69, Social Security $310.00, Medicare $72.50 and Connecticut income tax $217.30.
How the Connecticut paycheck calculation works
annual gross = gross per period x pay periods per year
federal withholding = IRS Pub 15-T annualised percentage method, de-annualised
Social Security = min(annual gross, $184,500.00) x 6.2% / periods
Medicare = annual gross x 1.45% / periods
state withholding = Connecticut income tax on annual gross / periods
take-home = gross per period - federal - Social Security - Medicare - state
Worked example
A single filer paid $5,000.00 every two weeks (26 pay periods a year) in Connecticut, for 2026:
- Annual gross = $5,000.00 x 26 = $130,000.00
- Federal income tax withheld this period = $766.69
- Social Security = $310.00; Medicare = $72.50
- Connecticut income tax withheld = $217.30
- Take-home = $5,000.00 - $766.69 - $310.00 - $72.50 - $217.30 = $3,633.51
Why Connecticut can withhold more than its brackets suggest
Connecticut take-home pay reflects one of New England's steeper income taxes. Alongside federal income tax, Social Security (6.2% to the 2025 base of $176,100), and Medicare (1.45%), Connecticut withholds under a seven-bracket schedule that runs from 2% on the first $10,000 of taxable income (single) up to 6.99% above $500,000, with married-filing-jointly thresholds set at double the single figures.
Two features make Connecticut's withholding heavier than a quick look at the brackets implies. First, the state has no conventional standard deduction; it grants a personal exemption ($15,000 single, $24,000 married filing jointly) that phases out entirely as income climbs, vanishing near $44,000 (single) and $71,000 (married filing jointly), so many middle-income filers get no shelter on their first dollars of pay. Second, a recapture provision claws back the benefit of the lower brackets at higher incomes, so a top earner effectively pays the top rate on all income.
That recapture can create a cliff, where a modest raise pushes a filer past a threshold and lifts state tax by more than the raise itself. Connecticut builds this into its withholding tables through Form CT-W4, so the state line on your check already reflects your income band. This estimate covers state income tax only and excludes Connecticut's separate Paid Family and Medical Leave payroll contribution.
