Louisiana Payroll Landscape
Louisiana underwent a major tax overhaul starting in 2025 that dramatically simplified its payroll environment. The state moved from a three-bracket progressive income tax to a flat 3% rate and is repealing its corporate franchise tax in 2026. These changes make Louisiana one of the more competitive southern states for payroll.
With a low flat tax rate, no local payroll taxes, and an SUI wage base matching the federal minimum of $7,000, Louisiana is now one of the simpler states for payroll compliance. The new employer SUI rate varies by industry, so employers should confirm their rate with the Louisiana Workforce Commission.
This guide breaks down each of Louisiana's employer obligations: registration requirements, 2026 tax rates and wage bases, filing deadlines, and the compliance pitfalls that catch expanding startups off guard. Whether you're hiring your first Louisiana employee or managing a growing remote team, everything you need to stay compliant is here.
