How This Calculator Works
Calculation methodology and assumptions
Payroll tax calculator for Connecticut. Employee taxes: Social Security 6.2% (up to $184,500 wage base), Medicare 1.45% (+ 0.9% Additional Medicare Tax above $200,000), federal income tax withholding, and Connecticut's real progressive state income tax brackets (up to 6.99%), applied marginally rather than as a single flat rate. Employer taxes: matching FICA (6.2% SS + 1.45% Medicare), FUTA (0.6% on first $7,000), and state unemployment insurance (SUTA rates vary by employer and are not modeled here).
Key State Information
Connecticut payroll facts: State income tax up to 6.99%. Median household income: $96,049. State minimum wage: $16.94/hr (above federal $7.25).
Example Calculation
Let's break down payroll taxes on a typical paycheck in Connecticut.
An employee earning Connecticut's median household income of $96,049/year, paid biweekly ($3,694 gross per check), single filer, no additional withholding. Per check: federal income tax ≈ $473, FICA ≈ $283, and Connecticut income tax ≈ $186.
Result: Employee take-home: approximately $71,568/year ($2,753/check) — an effective tax rate of 25.5%. Employers also pay a matching FICA share ($7,348/year) plus FUTA/SUTA, pushing total employer cost to roughly $103,897/year to employ this worker — 7-11% above salary.
