About Connecticut SUI rates
Connecticut employers pay state unemployment insurance (SUI, also called SUTA) on the first $27,000 of each employee's wages each year. New employers start at 3.1% until experience rating applies. Once rated, Connecticut rates run from 1.1% to 9.9%. Connecticut Department of Labor sets each employer's rate every year from its experience. Rates follow a benefit ratio: the benefits charged to the employer's account set against its taxable payroll. A higher ratio means a higher rate. Kreto-computed, not yet checked by a CPA.
If your rate notice looks wrong, Kreto checks it against the agency's 2026 schedule and shows the difference in dollars.
