How Louisiana taxes your paycheck
This page estimates the Louisiana income tax taken from your pay in 2026. Louisiana uses one flat rate, 3%, on your taxable income.
Before the rate applies, you subtract a standard deduction. For 2026 it is $12,838 if you're single or married filing separately. It's twice that, $25,676, for married couples filing jointly and heads of household. Louisiana has no state disability or paid leave tax, and no local income tax on wages.
Here is an example. A single person earns $60,000 and puts $3,000 in a 401(k). Louisiana taxes $57,000 minus $12,838, or $44,162. At 3%, that's about $1,324.86 for the year.

- Louisiana no longer has separate exemptions for dependents. The standard deduction replaced them in 2025.
- The 2026 withholding tables use 3.09% and a $12,875 deduction, so paychecks may withhold a bit more than the tax this page shows.
- The retirement income exemption ($12,324 for 2026) and Louisiana credits are left out.
Frequently asked questions

Does Louisiana tax 401(k) contributions?
No. Louisiana starts from your federal adjusted gross income, so traditional 401(k) and 403(b) contributions lower your Louisiana taxable income.
Why does my paycheck withhold more than 3%?
Louisiana's 2026 withholding tables use a 3.09% rate, a little above the 3% tax rate. If more was withheld than you owe, you get the difference back when you file.
