Connecticut paycheck taxes in 2026
Connecticut has a graduated income tax from 2% to 6.99%, with built-in exemption and tax-credit phase-outs plus a high-income recapture.
Withholding subtracts a personal exemption that phases out with income, then applies a personal tax credit that also phases out — so middle and upper earners get little or none of either.
Connecticut has no local income tax.

How your take-home pay is calculated
Your gross pay is what you earn before anything is taken out. Your take-home (net) pay is what's left after taxes and deductions. For a U.S. paycheck, the deductions are usually:
- Federal income tax withholding — based on your pay, filing status and Form W-4, using the IRS method below.
- Social Security — 6.2% of wages, up to the annual wage base ($184,500 in 2026).
- Medicare — 1.45% of all wages, plus an extra 0.9% on wages over $200,000 a year.
- State income tax — varies by state. Live and verified for California, New York (incl. New York City & Yonkers), Massachusetts, Illinois, Michigan, North Carolina, Colorado, Georgia, Pennsylvania, and the nine no-income-tax states; more added regularly.
- Pre-tax deductions — like a 401(k) or health premiums, which lower the tax you pay.
How federal withholding works (IRS Publication 15-T)
Employers don't guess. They follow the IRS percentage method in Publication 15-T. This calculator uses the exact same steps:
- Annualize your pay. Your gross for the period is multiplied by the number of pay periods in a year (26 for biweekly, 52 for weekly, and so on).
- Subtract a standard allowance. $8,600 for most filers, or $12,900 if married filing jointly (unless you checked Step 2 on your W-4), plus any Step 4(b) deductions.
- Apply the annual tax tables for your filing status to get the tentative yearly tax.
- Divide back across your pay periods, subtract your Step 3 credits, and add any Step 4(c) extra withholding.
Because we follow Pub 15-T to the letter, the federal numbers match what your employer's payroll system (and calculators like ADP and PaycheckCity) will show.
State income tax
State withholding is layered on top of the federal calculation. Nine states — Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington and Wyoming — take no income tax from wages, so your state line is $0. Others range from a single flat rate (Pennsylvania is 3.07% of pay) to full progressive brackets. California uses the state's official EDD Method B exact calculation — a low-income exemption, a standard deduction, progressive rate tables and an exemption-allowance credit — and also withholds State Disability Insurance (SDI) at 1.3% of all wages. New York uses its NYS-50-T exact-calculation tables, adds New York City or Yonkers resident tax depending on where you live, plus small Paid Family Leave and disability deductions. We add each state only once it's verified to the dollar against the state's own schedules; pick yours from the menu to see whether it's live yet.
Salary vs. hourly
For salary, your annual amount is simply divided across your pay periods. For hourly, we multiply your rate by your weekly hours across the year, add time-and-a-half for any overtime, then split it by your pay schedule. Either way the tax math is identical once we know your gross.
Bonuses, gross-ups & comparing offers
The Bonus tab uses the IRS percentage method for supplemental pay — a flat 22% federal rate (37% above $1 million) plus Social Security, Medicare and your state's supplemental rate — to show what you actually keep from a bonus or commission. Gross-up runs it in reverse: tell it the take-home you want someone to receive and it finds the gross bonus that nets it. And Compare puts two scenarios side by side — two job offers, a raise, or a move to another state — so you see the difference in real take-home pay, not just the headline salary. That's the moment this matters most: when you're weighing an offer, there's no paycheck to look at yet.
Why "no catch" matters here
Most paycheck calculators are lead funnels for payroll software or financial advisors — your numbers become someone's sales lead. PunchTally is different: there is no sign-up, no upsell, and nothing is stored or sold. Every calculation happens in your browser. Open your developer tools and watch — there are zero network calls when you calculate.
Frequently asked questions
- How much of my paycheck goes to taxes?
- It depends on income and filing status, but for a typical middle-income worker, federal withholding plus Social Security and Medicare often comes to roughly 15–25% of gross, before any state tax. Use the calculator for your exact figure.
- Why is my withholding different from a flat tax-bracket calculation?
- Withholding isn't your final tax bill — it's an estimate your employer pays the IRS during the year using Pub 15-T. Your actual tax is settled when you file. The two are close when your W-4 is accurate.
- Does a 401(k) reduce my taxes?
- Traditional 401(k) contributions reduce the wages subject to federal income tax, so less is withheld. They do not reduce Social Security or Medicare, which are still based on your full pay.
- How much tax comes out of a bonus?
- For a separately paid bonus, employers usually withhold a flat 22% for federal tax (37% on amounts over $1 million) plus Social Security, Medicare and any state supplemental tax. That's withholding, not your final tax — it's reconciled when you file. Use the Bonus tab for your figure.
- Is this calculator really free and private?
- Yes. No account, no email, no payment. Nothing you enter leaves your browser or is logged — you can verify there are no network requests.
