What is SUI?
Also known as State Unemployment Tax Act (SUTA) taxes, State Unemployment Insurance (SUI) is a state-based payroll tax that funds unemployment benefits and programs for out-of-work citizens.
SUI rates vary by state, but the tax is always paid along with Federal Unemployment Tax Act (FUTA) taxes to further assist citizens while they actively search for new employment.
