What is Louisiana's income tax rate in 2026?

Louisiana uses a flat 3.00% state income tax rate in 2026, after the state replaced its former graduated brackets with a single low flat rate.

How is Louisiana take-home pay calculated?

Take-home equals gross minus federal income tax (2026 progressive brackets), Louisiana's 3.00% flat state tax, Social Security (6.2% up to the $176,100 wage base) and Medicare (1.45%). The federal standard deduction is $15,750 single or $31,500 married filing jointly.

Is Louisiana's 3% rate one of the lowest?

Yes. Among states that levy a wage income tax, Louisiana's 3.00% flat rate is one of the lowest, so workers keep more of their salary than in states charging 4% to 6%.

Is this calculator exact?

It is a close estimate. It applies the headline 2026 federal brackets, the standard deduction, Louisiana's 3.00% flat rate and FICA, but excludes 401(k) contributions, itemized deductions, credits and other adjustments.

Louisiana take-home pay calculator

Estimate your Louisiana net pay after taxes. Louisiana applies a single flat 3.00% state income tax rate, one of the lowest among states that tax wages. This tool combines it with the 2026 federal income-tax brackets and FICA to show your real monthly and annual take-home pay.

How it works

The calculator subtracts four things from your gross salary. Federal income tax is charged on gross − standard deduction ($15,750 single, $31,500 married filing jointly) using the 2026 progressive brackets, so only the slice of income inside each band is taxed at that band’s rate. Louisiana state tax is a flat 3.00% applied to income after the same standard deduction. FICA adds Social Security at 6.2% up to the $176,100 wage base, plus Medicare at 1.45% on all wages. Net pay is gross minus all four.

Example

A single Louisiana worker earning $75,000: taxable income is $75,000 − $15,750 = $59,250. Federal tax across the 10%, 12% and 22% bands is about $7,747. Louisiana state tax is 3.00% of $59,250 = $1,778. Social Security is $4,650 and Medicare is $1,088. Total tax is roughly $15,262, leaving take-home pay near $59,738 a year, about $4,978/month, an effective rate of about 20.3%.
