Louisiana Tax Overview for Estimated Payments

Louisiana simplified its income tax to a flat rate of 3% for 2026, down from a previously tiered system with rates up to 4.25%. The flat rate applies uniformly to all income above a modest personal exemption. Louisiana's standard deduction of $12,875 is relatively generous. Louisiana has no local city income taxes on wages. Louisiana is notable for allowing residents to deduct federal income taxes paid on their state return — one of only a handful of states that does this, which reduces the effective state tax burden. Compared to neighboring Texas (no income tax) and Mississippi (4% flat), Louisiana's 3% rate is competitive. The overall state tax burden in Louisiana tends to be moderate, though sales taxes (among the highest in the nation when combined with local rates) affect overall affordability.
