Louisiana Payroll Tax Overview 2026
Louisiana uses a flat 3% income tax rate. All taxable income is taxed at the same percentage, regardless of how much you earn. This makes payroll calculations straightforward.
Louisiana moved to a 3.0% flat income tax in 2025, replacing a three-bracket system. This makes Louisiana one of the lowest flat-tax states.
Louisiana's flat 3% rate is the result of a 2024 ballot measure that also lowered the corporate tax rate to a flat 5.5%.
