About Connecticut SUI Rates
Connecticut employers pay State Unemployment Insurance (SUI/SUTA) taxes on the first $25,000of each employee's wages per year. New employers start at a rate of 3.10% before experience rating applies. Once rated, Connecticut SUI rates range from 1.00% to 10.00%.
SUI rates are set annually by Connecticut Department of Laborbased on each employer's experience rating — the ratio of benefits charged to the employer's account relative to taxable wages paid. Errors in SUI rate notices are common; Kreto verifies your assigned rate against payroll data and flags discrepancies before protest deadlines pass.
