State Unemployment Insurance (SUI)
State Unemployment Insurance (SUI) is a payroll tax that employers pay to their state to fund unemployment benefits for workers who lose their jobs. Each state sets its own taxable wage base and assigns employers an experience rate that rises or falls based on their history of layoffs and benefit claims. SUI is administered separately from the federal unemployment tax (FUTA).
Problem & Application
Seasonal businesses such as campgrounds, RV parks, and hospitality operators feel SUI sharply because heavy off-season layoffs can push their experience rate higher, raising payroll costs in future years. Multi-state STR and service operators also have to register and remit SUI in every state where they have employees, and missing a registration is a common source of payroll penalties. Check your current state agency guidance for your specific rate and wage base.
In Short
SUI is a state-by-state, history-driven payroll cost that rewards stable employment and punishes churn. Tracking it accurately protects both compliance and margins.
