How to use this calculator
- Choose salary or hourly, then enter your annual salary or your hourly rate and hours per week.
- Pick how often you're paid and your filing status. The state is already set to Connecticut.
- Enter your 401(k) contribution and any pre-tax health, HSA, or after-tax deductions per paycheck.
- If you filled in Steps 2–4 of a 2020-or-later Form W-4, open the Form W-4 section and enter the same values.
- Review your take-home pay and switch the breakdown between annual, monthly, and per-paycheck amounts.
How it's calculated
Federal income tax withholding follows the IRS Publication 15-T percentage method for automated payroll systems with a 2020-or-later Form W-4. Your wages are annualized, reduced by pre-tax deductions, adjusted for your W-4 entries, and run through the 2026 withholding rate schedule for your filing status. If you check the Step 2 box, the schedule uses half the standard deduction and half-width brackets, as the IRS tables do.
Social Security tax is 6.2% of wages up to the 2026 wage base of $184,500. Medicare tax is 1.5% of all wages, and employers withhold an extra 0.90% Additional Medicare Tax on wages above $200,000.
Connecticut taxes wages at rates from 2% to 6.99%, after a $15,000 standard deduction for single filers ($24,000 married filing jointly). The calculator applies the 2026 Connecticut brackets to your annual wages after the pre-tax deductions Connecticut allows, then divides by your number of paychecks.
Per-paycheck amounts are the annual amounts divided by your number of pay periods, rounded to the cent. Take-home pay is gross pay minus every tax and deduction line.
Assumptions
- Connecticut personal exemption phases out by 1% of the exemption per $1,000 of CT AGI above the threshold ($30k single / $48k MFJ) — modeled via adjust().
- CT does not recognize HSA contributions.
- CT property tax credit (up to $300) and other non-wage credits are not modeled.
- MFJ bracket thresholds used for HOH (HOH is treated similarly to MFJ in CT).
- Assumes you work one job for the whole year at the same pay, with no bonuses, commissions, or overtime. Supplemental pay is often withheld at a flat rate that isn't modeled here.
- Federal figures are withholding estimates, not your final tax bill. Your actual tax is settled when you file your return and can differ because of credits, other income, and itemized deductions.
- 401(k) contributions above the 2026 limit of $24,500 are flagged but not capped, since you may be eligible for catch-up contributions.
- Results are estimates for planning only. Check your pay stub or talk with your payroll department or a tax professional for exact figures.
Frequently asked questions
Does Connecticut have a state income tax?
Yes. Connecticut has a progressive income tax with rates from 2% to 6.99% for 2026. Higher rates apply only to the part of your taxable income in each bracket.
How much is taken out of a $60,000 paycheck in Connecticut?
A single filer earning $60,000 a year, paid biweekly with no pre-tax deductions, takes home about $1,862 per paycheck. About $193 goes to federal income tax, $177 to Social Security and Medicare, and $76 to Connecticut state taxes.
What are the 2026 Connecticut income tax brackets?
For single filers, 2% applies to taxable income from $0 to $10,000; 4.5% applies to taxable income from $10,000 to $50,000; 5.5% applies to taxable income from $50,000 to $100,000; 6% applies to taxable income from $100,000 to $200,000; 6.5% applies to taxable income from $200,000 to $250,000; 6.9% applies to taxable income from $250,000 to $500,000; 6.99% applies to taxable income over $500,000. The full tables for every filing status are below the calculator.
Does Connecticut tax 401(k) contributions?
No. Like the IRS, Connecticut excludes traditional 401(k) contributions from taxable wages, so contributing lowers both your federal and Connecticut income tax.
How is take-home pay calculated?
Start with gross pay, subtract pre-tax deductions like a traditional 401(k) and health premiums, then subtract federal income tax withholding, Social Security, Medicare, and any state or local taxes. Finally, subtract after-tax deductions like Roth 401(k) contributions. What's left is your net, or take-home, pay.
How much is taken out for FICA in 2026?
Employees pay 6.2% for Social Security on wages up to $184,500 and 1.5% for Medicare on all wages — 7.6% in total for most workers. Once your wages from one employer pass $200,000, your employer also withholds 0.90% Additional Medicare Tax.
Why is my paycheck different from this estimate?
Common reasons include benefits not entered here (commuter, dependent care, life insurance), bonuses or overtime withheld at a supplemental rate, local taxes, mid-year raises, or reaching the Social Security wage base partway through the year. Your employer may also use a slightly different state withholding formula.
Does a 401(k) contribution lower my taxes?
A traditional (pre-tax) 401(k) contribution lowers the wages subject to federal income tax and, in most states, state income tax. It doesn't lower Social Security or Medicare tax. A Roth 401(k) contribution comes out after taxes, so it doesn't lower your tax now, but qualified withdrawals in retirement are tax-free.
