Connecticut Tax Overview for 1099 Workers

Connecticut has a seven-bracket progressive income tax system with rates from 2% to 6.99%. Connecticut consistently ranks among the highest-tax states in the Northeast, with high property taxes, high income taxes, and a relatively high cost of living. The 6.99% top rate applies to income over $500,000, but middle earners face rates of 5.5-6.5% — well above the national average. Connecticut has no statewide local income tax on wages. One nuance: Connecticut offers a "tax benefit recapture" mechanism where higher earners effectively lose the benefit of lower brackets, meaning the marginal rate can appear higher for some income ranges. Compared to neighboring New York (up to 10.9%) and Massachusetts (5% flat), Connecticut sits in the middle but remains one of the heavier-taxed states nationally.
