Formula
Net Pay = Gross Pay − Pre-tax Deductions − Federal Tax − FICA − State Tax − Post-tax Deductions
FICA = 6.2% Social Security (up to wage base) + 1.45% Medicare (+0.9% above $200k)
Connecticut uses progressive state income tax brackets.
How to calculate
- Calculate your gross pay (salary ÷ pay periods, or hourly × hours).
- Subtract pre-tax deductions (401(k), HSA, insurance) to get taxable wages.
- Apply federal income tax withholding using IRS tables.
- Apply FICA: 6.2% Social Security + 1.45% Medicare.
- Apply Connecticut state income tax.
- Subtract post-tax deductions to find take-home pay.
Worked example
A single filer earning $75,000/year in Connecticut, paid biweekly with no extra deductions, will see federal tax, FICA, and Connecticut state tax withheld each pay period. Use the tool above for your exact numbers.

Connecticut paycheck — methodology and sources
Tax structure: Connecticut uses progressive state income tax brackets, so the marginal rate increases with taxable income. State withholding is applied on top of federal withholding and FICA. FICA: 6.2% Social Security up to the annual wage base, plus 1.45% Medicare on all wages (with an extra 0.9% above $200,000 for single filers). Pre-tax deductions like traditional 401(k), HSA, and most health-insurance premiums lower the wages subject to federal (and usually state) income tax. Local taxes (city, county, or school district) can apply in some areas and are not always reflected in a single statewide rate. For the most accurate withholding, verify against current guidance from the IRS (Publication 15-T) and the relevant Connecticut state tax agency. Useful references: IRS Publication 15-T (https://www.irs.gov/pub/irs-pdf/p15t.pdf), the IRS Tax Withholding Estimator (https://www.irs.gov/individuals/tax-withholding-estimator), and the Federation of Tax Administrators directory of state tax agencies (https://taxadmin.org/state-tax-agencies/).
