About the Connecticut Paycheck Calculator

Connecticut has a progressive state income tax with rates from 3% to 6.99%. This calculator uses Connecticut's actual 2025 tax brackets - applied after the Connecticut personal exemption ($16,100 single / $24,000 married) - alongside federal income tax, Social Security, and Medicare to give you a realistic take-home pay estimate.

Connecticut consistently ranks among the highest-tax states in New England. A single Connecticut filer earning $80,000 pays approximately $4,200–$5,000 in state income tax annually, on top of federal taxes and FICA. The calculator reflects the actual progressive bracket structure, not a single flat rate.

Results are bracket-based estimates. Connecticut has no local income taxes - all state income tax is collected at the state level. SDI (Connecticut's Paid Leave contribution, approximately 0.5% of wages) is not included in this calculator.

How the Tax Formula Works

This calculator uses a bracket-based approach - the same method used to compute annual tax liability - divided by your pay periods. It is an estimate, not a payroll withholding calculation (which uses W-4 inputs and IRS Publication 15-T procedures).

1Gross Pay = Hourly Rate × Hours OR Annual Salary ÷ Pay Periods
2Federal Taxable Income = Annual Gross − Standard Deduction (2025: $16,100 single / $32,200 married)
3Federal Income Tax = Apply 2026 IRS brackets (10%→37%) ÷ pay periods
4Social Security = Gross × 6.2% (stops at $184,500 annual wages)
5Medicare = Gross × 1.45% (+0.9% on wages over $200K single)
6Connecticut brackets: 3% → 5% → 5.5% → 6% → 6.5% → 6.9% → 6.99% - applied after CT personal exemption ($16,100 single / $24,000 married)
7Net Take Home = Gross − Fed Tax − SS − Medicare − State Tax

Results are bracket-based estimates. Actual paycheck withholding is determined by your W-4 form, pre-tax deductions, and employer payroll procedures. Use these results for planning and budgeting - not as a substitute for your actual pay stub.

Frequently Asked Questions - Connecticut Paycheck Calculator

Connecticut has seven income tax brackets for single filers in 2025: 3% on income up to $10,000; 5% up to $50,000; 5.5% up to $100,000; 6% up to $200,000; 6.5% up to $250,000; 6.9% up to $500,000; and 6.99% above $500,000. Connecticut provides a personal exemption of $15,000 (single) or $24,000 (married) that reduces taxable income. Married thresholds are approximately double the single filer amounts.
A single Connecticut filer earning $80,000 can expect approximately $56,000–$59,000 in annual take-home pay. Deductions include federal income tax (~$10,300 after standard deduction), Connecticut state tax (~$4,300 after $15,000 personal exemption), Social Security ($4,960), and Medicare ($1,160). Connecticut has no local income tax. Use the calculator for a per-paycheck estimate.
No. Connecticut does not impose any local or municipal income taxes - there is no city or county income tax on wages. The state's 2%–6.99% progressive rates are the only income taxes Connecticut workers pay at the state level. This is in contrast to neighboring New York, where NYC residents pay an additional 3.078%–3.876% city tax.
Connecticut partially taxes Social Security benefits. If your federal adjusted gross income (AGI) exceeds $75,000 (single) or $100,000 (married filing jointly), a portion of your Social Security benefits is subject to Connecticut income tax. Below those thresholds, Social Security benefits are fully exempt from Connecticut state tax.
Connecticut's Paid Leave program requires employees to contribute approximately 0.5% of wages to fund paid family and medical leave benefits. This contribution is separate from income tax and is not included in this calculator. Your actual take-home pay will be slightly lower than shown due to this additional deduction.
Connecticut employers use Form CT-W4 (Employee's Withholding Certificate) and Connecticut Department of Revenue Services withholding tables. Connecticut uses Withholding Code letters (A, B, C, D, F) based on filing status rather than numbered allowances, which can confuse employees accustomed to federal W-4 format. The benefit recapture provision for high earners means withholding can exceed what the bracket rates suggest. Official source: portal.ct.gov/DRS
Yes. Connecticut consistently ranks among the top 5 highest-tax states when combining state income tax, property tax, and sales tax. Property taxes in Connecticut are among the highest in the nation. However, Connecticut also has high average household incomes, particularly in Fairfield County near New York City, where many finance industry workers reside.
Key strategies: maximize traditional 401(k) contributions to reduce both federal and Connecticut taxable income, contribute to an HSA if eligible, and review your CT-W4 to ensure appropriate withholding. Connecticut does not offer a state deduction for 529 contributions. Review CT DRS Schedule CT-1040 for all available deductions and credits.
