≡How we calculate Connecticut take-home pay

Connecticut's income tax burden is meaningful, but the state's high salary levels — particularly in finance and insurance in Fairfield County — often more than compensate. Fairfield County workers commuting to New York City face Connecticut income tax rather than NYC city tax, which can be a net financial advantage. Many Connecticut residents work in New York City. For those who have transitioned to remote work, Connecticut's income tax compares favorably to New York City's combined state and city tax burden, and housing costs are generally lower than comparable NYC suburbs.
