How much is taken out of my paycheck in Connecticut?

Federal income tax, FICA at 7.65% (Social Security + Medicare), and Connecticut's progressive income tax (2% to 6.99%). Connecticut has no local income tax. Enter your pay above for the federal, FICA, and state split.

What is the Connecticut income tax rate in 2026?

Connecticut has seven brackets from 2% up to 6.99%, after a personal exemption. A 2024 cut lowered the two lowest rates (to 2% and 4.5%), so most middle-income workers pay an effective rate in the 4% to 5.5% range.

How does Connecticut's personal exemption work?

Single filers start with a $15,000 exemption ($24,000 married) that shrinks by $1,000 for every $1,000 of income above $30,000 ($48,000 married), disappearing entirely at $45,000 single. This calculator applies the phased-down exemption automatically.

What's my take-home pay in Connecticut?

Take-home is your gross minus federal tax, FICA, Connecticut income tax, and any pre-tax contributions. This estimate doesn't model Connecticut's small rate phase-out, high-income recapture, or low-income tax credit, so it's a close ballpark. The breakdown table above shows the details.

How your Connecticut take-home pay is calculated

Your gross pay is what you earn before anything is withheld; your take-home (net) pay is what actually lands in your bank account. Between the two sit several deductions, applied in a specific order. This calculator walks gross pay through pre-tax deductions, federal income tax, FICA, and Connecticut state tax to estimate what you keep each paycheck.

The deductions, step by step

Pre-tax deductions, traditional 401(k), HSA, and pre-tax health premiums come out first and lower your taxable income (your 401(k) still counts for Social Security and Medicare, though).
Federal income tax, applied to income after the standard deduction using the 2025 progressive brackets for your filing status.
FICA, Social Security at 6.2% (up to the annual wage base) plus Medicare at 1.45% on all wages, with an extra 0.9% on wages above $200,000.
Connecticut tax, Connecticut's rates run 2% to 6.99%, applied after a personal exemption ($15,000 single / $24,000 married) that phases out as income rises. This estimate models the exemption and brackets, but not Connecticut's small 2%-rate phase-out add-back, its high-income tax recapture, or its personal tax credit (which lowers tax for lower earners), so it can run slightly high for low incomes and slightly low for very high ones. Connecticut has no local income tax.

Biweekly vs. monthly, does it change your taxes?

No. Your total annual tax depends on what you earn in a year, not how often you're paid. A biweekly schedule (26 checks) simply slices the same annual take-home into smaller, more frequent amounts than a monthly schedule (12 checks). Switch the pay-frequency selector above and you'll see the per-paycheck figure change while the annual totals stay put.

Make your estimate more accurate

Set your real 401(k) percentage and HSA amount, pre-tax contributions can noticeably raise take-home-adjusted savings.
Choose the filing status that matches your W-4; married filing jointly widens the brackets.
Add your pre-tax health premium if your employer deducts it before taxes.

This is an estimate of annual tax liability, not exact per-paycheck withholding (which follows IRS Pub 15-T tables and your specific W-4). It uses 2025 federal and FICA figures and doesn't model local city taxes, post-tax deductions, or tax credits. Treat the result as a close ballpark, and check your actual pay stub for the precise numbers.
