The New Orleans, Louisiana skyline at golden hour along the Mississippi River.

Louisiana overhauled its income tax for 2025, replacing graduated brackets that topped out at 4.25% with a single flat 3.0% rate and a larger standard deduction.

That reform lowered the income-tax bill for most workers, though Louisiana still leans on some of the nation's highest sales taxes. Here is how the new flat rate works on your paycheck. See your exact take-home with the free Louisiana paycheck calculator.

How Louisiana's income tax works

Louisiana applies a flat 3.0% to your income after a combined standard deduction of $12,500 single / $25,000 married (2025). There are no brackets to climb and no local income tax on wages, so the state portion is simple and low.

The flat 3% replaced a graduated system (2%, 3.5%, 4.25%) starting in 2025, part of a broader reform that also adjusted the standard deduction and corporate rates.

Your take-home on a $65,000 salary in Louisiana

Here is how a $65,000 salary breaks down for a single filer, using 2025 federal and FICA figures alongside Louisiana's a flat 3.0% income tax.

ItemAnnual
Federal income tax$5,246
FICA (Social Security + Medicare)$4,973
Louisiana income tax$1,575
Take-home pay$53,207
Percent of gross kept81.9%

On a $65,000 salary a single filer owes only about $1,575 in Louisiana income tax and keeps roughly $53,207, or 81.9% of gross, one of the higher take-home rates among income-tax states after the 2025 reform. Bear in mind Louisiana's combined state-and-local sales tax is among the nation's highest (often around 9.5% to 10%), so more of the tax burden shows up at the register than on your paycheck. Compare with Texas.

A brand-new flat rate, high sales taxes

Louisiana's 2025 reform is the headline: a flat 3% with a bigger standard deduction replaced the old graduated brackets, cutting the income-tax bill for most filers. The trade-off is that Louisiana funds itself heavily through sales tax, which is among the steepest in the country.

Louisiana exempts Social Security and offers exclusions for many forms of retirement income, so retirees often pay little or no state income tax.

How to keep more of your Louisiana paycheck

Because the flat 3% applies to a federal-style base, a traditional 401(k) and HSA lower your Louisiana and federal taxable income together (and the HSA avoids FICA), the cleanest lever on your take-home in a low-rate state.
