Overview: What Makes Hawaii Payroll Complex

Hawaii's payroll environment is more complex than most people expect. The state has 12 income tax brackets (the most in the country), one of the highest SUI wage bases at $64,500, mandatory temporary disability insurance, and a unique Prepaid Health Care Act that requires employers to provide health insurance to employees working 20+ hours per week.

This guide breaks down each of Hawaii's employer obligations: registration requirements, 2026 tax rates and wage bases, filing deadlines, and the compliance pitfalls that catch expanding startups off guard.
