How to Use This Calculator
Tab "Take-Home Pay"
Enter your gross annual salary, pay frequency, and filing status. The calculator applies 2026 federal income tax brackets, Connecticut state income tax brackets (3%–6.99%), and FICA taxes (Social Security 6.2% up to $184,500, Medicare 1.45%, and the 0.9% Additional Medicare Tax above $200K). Connecticut has no standard deduction — instead, a personal exemption credit is applied, which phases out at higher incomes. Expand "More options" to add pre-tax 401(k) contributions and health insurance premiums. The result shows your net take-home per paycheck plus a full annual summary.
Tab "Tax Breakdown"
This tab shows a visual pie chart of where every dollar of your salary goes: federal tax, CT state tax, Social Security, Medicare, and take-home pay. It calculates how many cents of each dollar you actually keep and your combined effective tax rate. Connecticut has no SDI or local taxes, so your state deductions are simpler than states like California or New York.
Tab "Compare Filing Status"
See your take-home pay calculated side-by-side as Single, Married Filing Jointly, and Head of Household. The comparison table shows federal tax, CT state tax, FICA, and net take-home for each status. The best option is highlighted in green. Note that Connecticut’s personal exemption credit and bracket thresholds differ significantly between filing statuses.
The Formulas
Taxable income = Gross salary − Pre-tax deductions − Standard deduction
Single: $15,750 · MFJ: $31,500 · HoH: $23,500
Tax = Sum of (taxable income in each bracket × bracket rate)
Brackets: 10%, 12%, 22%, 24%, 32%, 35%, 37%
Connecticut State Income Tax (2026 DRS rates):
CT taxable income = Gross − Pre-tax deductions (NO standard deduction!)
Bracket tax = Sum of (CT taxable in each bracket × rate)
Single brackets: 3% ($0–$10K), 5% ($10K–$50K), 5.5% ($50K–$100K), 6% ($100K–$200K), 6.5% ($200K–$250K), 6.9% ($250K–$500K), 6.99% ($500K+)
MFJ brackets: 3% ($0–$20K), 5% ($20K–$100K), 5.5% ($100K–$200K), 6% ($200K–$400K), 6.5% ($400K–$500K), 6.9% ($500K–$1M), 6.99% ($1M+)
Personal Exemption Credit:
Base credit = 75% × min($15,000, exemption) = $112.50 (single) / $225 (MFJ)
Phase-out: credit reduces by $10 per $1,000 of CT AGI above $56,500 (single) / $100,500 (MFJ)
Net CT tax = Bracket tax − Personal exemption credit (min $0)
FICA Taxes:
Social Security = 6.2% × min(Gross salary, $184,500)
Medicare = 1.45% × Gross salary
Additional Medicare = 0.9% × max(0, Gross − $200,000)
Take-Home Pay:
Net = Gross − Federal tax − CT tax − SS − Medicare − Pre-tax deductions
Per paycheck = Net ÷ Number of pay periods
Unlike most states, Connecticut has no standard deduction. Your entire income (minus pre-tax deductions like 401(k)) is subject to CT income tax. The personal exemption credit partially offsets this for lower earners, but it phases out completely for single filers above approximately $67,750 and MFJ filers above approximately $123,000.
Example
$80,000 Salary — Single, Biweekly, No 401(k)
On an $80,000 salary in Connecticut, you keep about 76.1 cents of every dollar. Your combined effective tax rate is 23.9%. The largest chunk goes to federal income tax ($9,049), followed by Social Security ($4,960) and CT state tax ($3,950). Note that the CT tax is calculated on the full $80,000 with no standard deduction — the personal exemption credit is fully phased out at this income level ($80K is well above the $56,500 phase-out threshold for single filers). Adding a 6% 401(k) contribution would reduce your federal and CT taxable income by $4,800, saving roughly $1,300 in taxes.
