How we calculate the effective tax rate in Connecticut

We run fixed gross salaries through our US paycheck engine for a single filer in tax year 2026, with Connecticut selected. Modeled withholdings include federal income tax, state income tax (when applicable), and employee payroll (FICA plus any modeled state disability / paid family leave premiums). Effective rate = total modeled tax ÷ gross.

Results are educational estimates for comparing jurisdictions — not a substitute for your W-2 stub or a filed return. Local city taxes, benefits deductions, and non-paycheck levies (sales, property) are excluded.
