Louisiana Income Tax Rate
3.00% flat rate
Everyone pays 3.00% of taxable income, regardless of income level or filing status.
What People Get Wrong
“A flat 3% tax means I pay 3% of my salary in Louisiana.”
Louisiana's 3% applies only to income above the standard deduction ($12,875 single, $25,750 married), so most middle-income earners pay well under 3% of their salary. Someone earning $75,000 pays $1,864 (2.5%), while the same earner in a flat-tax state like Illinois would pay $3,713 (4.95% flat).
“Louisiana has low taxes because of the low income tax rate.”
While Louisiana's flat 3% income tax rate is low, 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.
“The low 3% rate means I'll pay less than in other states.”
While Louisiana's 3% flat income tax rate is lower than most 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 $1,864 in income tax (2.5% effective) plus $4,725-$5,725 in sales tax (9.45%-11.45%), totaling $6,589-$7,589 (8.8%-10.1% of income). The high sales tax disproportionately affects lower earners and big spenders.
Key Facts That Affect Your Take-Home Pay
- Louisiana taxes income at a single flat 3% rate after the standard deduction ($12,875 for single filers, $25,750 for married couples filing jointly), one of the lowest flat income tax rates in the country.
- Because the 3% rate applies only after the $12,875 standard deduction, Louisiana's effective rates stay well below 3% for most workers: a $50,000 earner pays $1,114 (2.2% of salary) and a $75,000 earner pays $1,864 (2.5%).
- Louisiana does not require income tax at the local level, so your withholding remains consistent statewide. All Louisiana residents face the same flat 3% state rate.
