Louisiana Income Tax Overview

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 the state's standard deduction of $12,875 for single filers. Louisiana is one of the very few states in the country that allows residents to deduct their federal income taxes paid when calculating state taxable income — this federal deduction provision meaningfully reduces the effective state rate for most earners. No Louisiana city charges a local income tax on wages, so workers in New Orleans, Baton Rouge, Shreveport, and Lafayette all face the same effective rate statewide.

Here's what a single Louisiana filer keeps in 2026. On a $50,000 salary, take-home is approximately $41,100 per year ($3,425/month) after federal, FICA, and state taxes. At $80,000, take-home is approximately $62,600 ($5,217/month). At $100,000, you keep about $76,100 ($6,342/month). At $150,000, take-home is approximately $109,100 ($9,092/month). The federal deduction benefit makes the effective Louisiana state rate closer to 2–2.5% for most middle-income earners — lower than the headline 3% suggests.

Compared to neighboring Texas (no income tax), a Louisiana worker at $80,000 takes home approximately $1,978 less per year — a relatively small gap for a state that does have an income tax. Against Mississippi (4% flat rate), Louisiana's 3% plus the federal deduction benefit makes it more favorable by roughly $700–$900 per year at middle incomes. Against Arkansas, which also has a flat rate structure, Louisiana is competitive. The low 3% rate positions Louisiana well among income tax states in the South.

Watch out: Louisiana's combined state and local sales taxes are among the highest in the country. New Orleans has a combined rate of around 9.45%, and many parishes (Louisiana's term for counties) add local sales taxes on top of the 4.45% state rate, bringing combined rates to 10–11% in some areas. The income tax savings at 3% can be partially offset by high sales tax exposure, especially for high-spending households. If you're comparing Louisiana to a no-income-tax state like Texas, factor in that Texas also has no state income tax but similarly high sales tax rates — so on balance, Louisiana's income tax is the primary cost difference.
