Quick answer
Connecticut paycheck basics
Connecticut taxes wages at seven rates from 2% to 6.99%, and it phases out the benefit of its lower rates, its personal exemption and its personal tax credit as income rises. That is why Connecticut does not publish a simple percentage method: employers use the Department of Revenue Services' withholding calculation rules, which work from your annualized salary and the withholding code letter you choose on Form CT-W4. Every paycheck also carries a 0.5% CT Paid Leave contribution.
This calculator follows the 2026 rules, TPG-211, step by step. Pick the code from line 1 of your CT-W4 and any extra or reduced amount from lines 2 and 3, and it figures Connecticut withholding and CT Paid Leave along with federal income tax, Social Security and Medicare to show your take-home pay.
How Connecticut taxes your paycheck
Connecticut withholding starts from your annualized salary and your CT-W4 code. A personal exemption from Table A comes off: $15,000 for code F (single), $12,000 for code A, $19,000 for code B (head of household) and $24,000 for code C, each shrinking by $1,000 for every $1,000 of salary above a threshold until it disappears; code D gets none. The rest is taxed with Table B: 2% on the first $10,000 for a single filer, then 4.5%, 5.5%, 6%, 6.5%, 6.9% and 6.99% above $500,000, with brackets 1.6 times as wide for code B and twice as wide for code C. Table C adds back part of the 2% bracket for higher salaries and Table D recaptures the benefit of the other lower rates for high earners. Finally a personal tax credit from Table E, as much as 75% for low salaries and none above about $52,500 for a single filer, reduces the result, which is divided by your paychecks. Bonuses paid with regular wages are withheld as one payment. Traditional 401(k) deferrals reduce Connecticut wages as they do federal wages.

Connecticut state payroll programs
CT Paid Leave is funded entirely by employees: 0.5% of wages, up to the Social Security wage base of $184,500 for 2026, for a maximum of $922.50 a year. It pays up to 12 weeks of partial wage replacement for your own serious health condition, a family member's, or a new child.

Frequently asked questions
How is federal income tax withheld from my paycheck calculated?+
Employers use the IRS Publication 15-T percentage method with the elections on your Form W-4: filing status, whether Step 2 is checked, Step 3 credits, and any Step 4 adjustments. That produces an amount to withhold each pay period before Social Security, Medicare, and any state or local tax are applied.
What is FICA and why is it withheld on every paycheck?+
FICA is Social Security tax (6.2% of wages up to the annual Social Security wage base) plus Medicare tax (1.45% of all wages, with an extra 0.9% on wages above $200,000 in a year). Both are withheld on every US paycheck regardless of which state you work in, because they fund federal programs rather than a state one.
Is the result on this calculator the same as my actual paycheck?+
It is an estimate for planning, not a substitute for your pay stub. Your actual withholding depends on the exact elections on file with your employer, your specific pay dates, and any mid-year changes to your deductions — the calculator applies the published federal and state formulas to the numbers you enter.
What are the Connecticut income tax rates for 2026?+
Seven rates: 2%, 4.5%, 5.5%, 6%, 6.5%, 6.9% and 6.99%. For a single filer the 2% rate covers the first $10,000 of taxable income and 6.99% applies above $500,000. Head-of-household brackets are 1.6 times as wide and married-filing-jointly brackets twice as wide.
Which withholding code should I choose on Form CT-W4?+
Single filers earning over $15,000 use F. Married couples filing jointly use C if only one spouse works and A if both work (and their combined income is up to $100,500; above that, D). Heads of household earning over $19,000 use B. Code D gives the most withholding, and E means no withholding is needed because your income is below the filing threshold.
How much Connecticut tax is withheld on a $60,000 salary?+
For a single employee (code F) paid biweekly, the $59,999.94 annual salary has no personal exemption at that income. Table B gives $2,549.99, Table C adds $25, and the 10% personal tax credit from Table E leaves $2,317.50 a year, or about $89.13 per paycheck. CT Paid Leave adds $11.54.
What happens if I don't give my employer a CT-W4?+
Your employer is required to withhold at the highest rate, 6.99%, with no exemption. For most people that is much more than they owe, so it is worth filing a CT-W4.
What is CT Paid Leave and how much is deducted?+
CT Paid Leave is Connecticut's paid family and medical leave program. Employees pay for it through a 0.5% payroll deduction on wages up to the Social Security wage base, $184,500 in 2026, so the most anyone pays is $922.50 for the year. Employers do not contribute to the state-run plan.
How are bonuses taxed in Connecticut?+
A bonus paid with your regular wages is added to that paycheck and withheld as if it were one payment for the period. There is no separate flat Connecticut supplemental rate for bonuses paid with regular pay.
Does Connecticut tax 401(k) contributions?+
No. Traditional 401(k), 403(b) and 457 deferrals and pretax health benefits reduce Connecticut wages the same way they reduce federal wages. They are still subject to the CT Paid Leave contribution, which follows Social Security wages.
Why do two-earner couples get too much or too little withheld?+
Connecticut's personal exemption and tax credit phase out based on a couple's combined income, but each employer only sees one paycheck. If both spouses choose code A, DRS suggests checking the supplemental tables in IP 2026(7) and adding extra withholding on line 2 or reducing it on line 3.
What is the minimum wage in Connecticut?+
$16.94 an hour from January 1, 2026. It is adjusted every January for the change in the employment cost index.
