Income tax in Louisiana

Louisiana replaced its graduated brackets with a flat 3.0% rate effective January 1, 2025, paired with a much larger standard deduction of $12,500 (single) or $25,000 (married filing jointly). The old personal-exemption structure was folded into the new standard deduction, and taxpayers 65 and older can exempt additional retirement income.
