Louisiana Income Tax Rate
3.00% flat rate
Everyone pays 3.00% of taxable income, regardless of income level or filing status.
Key Facts That Affect Your Take-Home Pay
- Louisiana uses a progressive income tax system with three brackets, starting at 1.85% for the first $12,500 of income (single) or $25,000 (married) and escalating to a top rate of 4.25% for income above $50,000 (single) or $100,000 (married), making Louisiana's bracket structure simple with a relatively low top rate compared to other progressive states.
- Louisiana's progressive brackets are relatively spread out at the bottom but compressed at higher income levels, meaning middle-income earners gradually move through brackets while high earners reach the top 4.25% rate. For a $75,000 earner, income is taxed across multiple brackets creating an effective rate around 3.5%-4%, not the top 4.25% rate.
- Louisiana does not require income tax at the local level, so your withholding remains consistent statewide. All Louisiana residents have the same income tax structure—only the state progressive brackets apply.
Common Mistakes People Make
Misconception: 'Progressive tax means I'll pay the top 4.25% on all my income in Louisiana.' Reality: Louisiana's progressive system starts at just 1.85% for the first $12,500-$25,000 of income (depending on filing status), and most middle-income earners pay effective rates around 3%-4%, not 4.25%. The 4.25% rate only applies to income above $50,000 (single) or $100,000 (married). Someone earning $75,000 pays an effective rate around 3.5%-4% (~ $2,625-$3,000 annually), while the same earner in a flat-tax state like Illinois would pay $3,713 (4.95% flat).
Misconception: 'Louisiana has low taxes because of the low income tax rate.' Reality: While Louisiana's top income tax rate is relatively low (4.25%), the state compensates with very high sales taxes (9.45%-11.45% in many areas, among the highest combined rates in the nation). A big spender in Louisiana might pay more in sales tax than they'd pay in income tax in some other states. Lower-income residents who spend a large percentage of income on taxable goods face a particularly regressive tax burden. Factor in both income tax and sales tax when evaluating Louisiana's tax burden.
Misconception: 'The low top rate of 4.25% means I'll pay less than in other states.' Reality: While Louisiana's 4.25% top income tax rate is lower than many states, the very high sales tax rates (9.45%-11.45% in many areas) can offset the income tax advantage for big spenders. A $75,000 earner who spends $50,000 annually on taxable goods might pay $2,900 in income tax (~ 3.9% effective) plus $4,725-$5,725 in sales tax (9.45%-11.45%), totaling $7,625-$8,625 (10.2%-11.5% of income). The high sales tax disproportionately affects lower earners and big spenders.
One Thing to Know
Louisiana has some of the highest combined sales tax rates in the nation (up to 11.625% in some areas), which can completely offset the low 4.25% income tax top rate for big spenders. Many people see the low income tax rate on their paycheck and don't realize how much they're paying in sales tax until they track their annual spending.
