How Our Connecticut Tax Calculator Works

Our Connecticut tax calculator analyzes your gross pay and calculates federal taxes, Social Security, Medicare, and Connecticut's progressive state income tax. The calculation considers Connecticut's seven-tier tax system and uses current 2024 tax rates to provide accurate take-home pay estimates with comprehensive tax analysis.

Connecticut Tax Calculation Formula

Taxable Income = Gross Pay - Pre-tax Deductions
Federal Tax = Progressive Tax Bracket Calculation
Social Security Tax = Taxable Income × 6.2% (up to wage base)
Medicare Tax = Taxable Income × 1.45% (+ 0.9% surtax if applicable)
Connecticut State Tax = Progressive Brackets (3.0% - 6.99%)
Net Pay = Gross Pay - All Taxes - Post-tax Deductions

This formula calculates your Connecticut paycheck with federal taxes, Social Security, Medicare, and Connecticut's progressive state income tax. The progressive system means higher earners pay a higher percentage in state taxes across seven brackets.
