Connecticut Take-Home Pay Calculator (2026)

Connecticut has a graduated income tax with a top rate of 6.99%, which kicks in at $500,000 of taxable income for single filers. Below that, rates range from 2% to 6.9%, with the effective rate for most middle-income workers landing somewhere between 4% and 6%. A single filer earning $70,000 in Connecticut typically owes around $3,000 to $3,500 in state income tax after the standard exemption.

Connecticut taxes Social Security income for high earners, which is notable since many states either fully or partially exempt Social Security from state taxes. Connecticut exempts Social Security from state tax for individuals with federal AGI below $75,000 and married couples below $100,000. Above those thresholds, Social Security income is taxable at regular Connecticut rates.

The state imposes a pass-through entity tax, which affects self-employed workers and business owners more than W-2 employees. For wage earners, the main state tax variables are the bracket rates and the exemption amounts. Connecticut's personal exemptions phase out for higher earners, which means effective rates for upper-middle-income workers can be higher than a simple rate table suggests.

Connecticut has no local income taxes, so the state rate is the complete income tax picture. The state does have relatively high property taxes and a high cost of living, particularly in Fairfield County and the Hartford area. Workers evaluating total compensation in Connecticut should factor in property tax costs if they own a home, as they can add substantially to the overall tax burden.
