Louisiana Paycheck Calculator (2026)

Estimate your Louisiana take-home pay after federal tax, FICA, and Louisiana state income tax (flat 3%). No local tax and no second Louisiana payroll tax.

How this calculator works

Like our other paycheck calculators, this estimates federal tax and FICA the same way regardless of state. On top of that, it applies Louisiana’s flat 3% state income tax to your Louisiana taxable income: your federal-taxable wages, minus Louisiana’s own 2026 standard deduction ($12,875 single/married filing separately, $25,750 married filing jointly/head of household).

Louisiana has no second state-level payroll tax like Colorado’s FAMLI premium, and no local or municipal income tax anywhere in the state, so Louisiana’s state-tax line is a single number. One quirk worth knowing: Louisiana’s own payroll withholding tables use a slightly higher 3.09% rate on purpose, as a cushion against underwithholding, with any excess refunded at filing. This calculator estimates your actual annual tax liability at the true 3% rate, not that withholding cushion.

The formula

(federal tax, FICA, and net-pay assembly are identical to the Colorado calculator)

laTaxableIncome = max(0, wagesAfterPretax − louisianaStandardDeduction)
                (louisianaStandardDeduction: $12,875 single/MFS, $25,750 joint/HOH)
laIncomeTax     = laTaxableIncome x 3%

stateTax = laIncomeTax

Worked example

A single filer earning $60,000/year, paid biweekly, with no 401(k) or extra deductions:

  • FICA: $4,590.00/year (6.2% + 1.45% of $60,000, same as any state)
  • Federal tax: $5,020.00/year ($60,000 minus $16,100 standard deduction = $43,900 taxable, same as any state)
  • Louisiana taxable income: $60,000 minus $12,875 standard deduction = $47,125
  • Louisiana income tax: $47,125 x 3% = $1,413.75/year
  • Net pay: $60,000 minus $4,590.00 minus $5,020.00 minus $1,413.75 = $48,976.25/year, or $1,883.70 per biweekly paycheck

We checked our income-tax math against the Louisiana Department of Revenue’s own R-1306 withholding-formula document, which walks through two worked examples using the same $12,875/$25,750 standard deductions. Its examples use the 3.09% withholding rate (not the 3% actual tax rate), and applying that same 3.09%-vs-3% cushion to our numbers lines up almost exactly: for a $36,400/year single filer, the department’s own worked example computes $726.96 in annual withholding, and 3% of the same taxable income is $705.75, a $21.21 gap that matches the intended 3.09/3.00 cushion ratio to within a few cents.

Frequently asked questions (FAQ)

What is Louisiana's 2026 state income tax rate?

A flat 3% on Louisiana taxable income, the same rate for every filer regardless of income. Louisiana replaced its old graduated brackets, which ran from 1.85% up to 4.25%, with this single flat rate starting with the 2025 tax year under a major reform law, and the rate stays at 3% for 2026.

What is Louisiana's standard deduction for 2026?

$12,875 for single filers and married filing separately, and $25,750 for married filing jointly, qualifying surviving spouse, or head of household. These figures come from the same reform law and are adjusted each year for inflation, up from $12,500 and $25,000 respectively when the reform first took effect for 2025.

Why does my paystub show a Louisiana withholding rate closer to 3.09% instead of 3%?

Louisiana's own withholding tables intentionally use 3.09%, not the true 3% tax rate, to build in a small cushion against underpayment. Any amount withheld above your actual tax liability is refunded when you file. This calculator estimates your actual annual liability at the true 3% rate, not the withholding cushion.

Does Louisiana have a state disability insurance or paid family leave payroll tax?

No. Unlike California, Colorado, New Jersey, New York, and a handful of other states, Louisiana does not operate any mandatory employee-paid disability or paid-family-leave program. Louisiana unemployment insurance is funded entirely by employers, so Louisiana income tax is the only state-level deduction this calculator applies.

Does any Louisiana parish or city have its own local income tax?

No. Louisiana parishes and municipalities cannot levy a local income tax that requires payroll withholding, unlike Pennsylvania, Ohio, Michigan, Indiana, or Kentucky, where many cities and counties add their own wage tax. Some Louisiana cities charge a local occupational license tax, but that's a business fee, not a tax withheld from your paycheck.

Does contributing to a 401(k) lower my Louisiana state tax the way it lowers my federal tax?

Yes. Louisiana taxable income starts from the same federal-taxable-wages figure used for your federal tax, which is already reduced by your 401(k) elective deferrals. Contributing more to a 401(k) lowers both your federal and your Louisiana taxable income by the same dollar amount.

Why is my actual Louisiana paycheck different from this calculator's estimate?

This calculator spreads your estimated annual tax liability evenly across paychecks at the true 3% rate, while your employer's actual withholding uses Louisiana's 3.09% withholding-table cushion rate and your Form L-4 elections, which don't produce an identical per-paycheck amount. Any difference shows up as a refund or balance due when you file.
