Connecticut Income Tax Rates 2026

All Payroll Deductions in Connecticut

Connecticut vs Federal Tax: What's Different
Your Connecticut state tax is calculated on state taxable income (gross minus Connecticut's standard deduction of $15,000). Federal tax uses a $15,000 standard deduction (single, 2026). The rates and brackets are independent — state tax is not a deduction from federal tax.
