Louisiana Income Tax Overview

Louisiana's personal income tax has been a flat 3% since 2025, when the state replaced its 1.85%-4.25% brackets with a single rate, one of the lower rates among states that tax wages at all. A single filer first subtracts a $12,500 standard deduction ($25,000 for joint filers and heads of household), which keeps the first slice of earnings outside the tax entirely and pulls the effective rate below 3%: on $60,000 of income a single filer owes 3% of $47,500, or $1,425, an effective 2.4%.

This tax runs alongside the federal income tax, not in place of it. The two are figured on separate returns under separate rules, and the Louisiana Department of Revenue administers the state side. Residents owe it on their full income, while nonresidents owe it on income sourced to Louisiana, such as wages earned or property rented here. Because the rate is 3% at every income level, even high earners hand over a modest share of income to the state compared with high-tax jurisdictions.

Louisiana Income Tax FAQ

What is the highest income tax rate in Louisiana?
The rate is a flat 3%, the same on every taxable dollar; there are no higher brackets. Because the $12,500 standard deduction ($25,000 for joint filers) comes off first, your effective rate on total income always lands below 3%.
How does Louisiana tax stack on top of federal tax?
They are calculated independently and reported separately. Your federal liability is figured on the IRS 1040 using federal brackets, and your Louisiana liability is figured on the state return at the flat 3% rate. Neither replaces the other, so a Louisiana worker owes both, but the state portion is small relative to the federal bite for most earners.
Who has to file a Louisiana return?
Residents and part-year residents who owe state tax generally must file, and so must nonresidents who earn Louisiana-source income like wages, business profits, or rental income. Filing also makes sense when tax was withheld and you are owed a refund. The state return goes to the Louisiana Department of Revenue and is distinct from your federal filing.
What does the $12,500 standard deduction do for a single filer?
It removes the first $12,500 of income from the state tax base before the 3% rate applies, so that amount is never taxed by Louisiana. The deduction lowers your taxable income rather than cutting your tax bill dollar-for-dollar, so it is worth $375 in tax (3% of $12,500). Income above it is taxed at the same flat 3%.
