Louisiana Paycheck Calculator

How to estimate your Louisiana take-home pay in 2026

Louisiana applies a flat 3% state income tax rate on wages after a generous standard deduction. This calculator estimates your 2026 net pay after federal withholding, FICA payroll taxes, and Louisiana state tax so you can plan monthly expenses and compare job offers with confidence.

Enter your annual salary or build it from hourly wages using our gross pay calculator. If you receive 26 paychecks per year, the biweekly pay calculator shows how gross and net amounts spread across the calendar. For federal tax details and dependent credits, see the income tax calculator and salary calculator.

What gets deducted from a Louisiana paycheck

A typical Louisiana W-2 paycheck includes three layers of mandatory withholding plus any voluntary deductions you elect through your employer:

• Federal income tax: Calculated from 2026 IRS brackets, your W-4 filing status, and qualifying child tax credits.
• FICA taxes: Social Security at 6.2% (capped at the 2026 wage base of $184,500) and Medicare at 1.45%, with an additional 0.9% on wages above $200,000 for single filers. Use our FICA tax calculator to isolate these amounts.
• Louisiana state income tax: A flat 3% applied to gross wages after pre-tax deductions and the Louisiana standard deduction.

Louisiana does not levy a separate state disability insurance tax. Pre-tax 401(k) contributions and HSA deposits reduce gross wages before Louisiana taxable income is calculated, lowering overall withholding.

How Louisiana flat tax is calculated

Louisiana taxable income starts with gross wages after pre-tax deductions, then subtracts the state standard deduction before applying the flat rate:

For 2026, Louisiana standard deductions are $12,875 (single), $25,750 (married filing jointly), and $25,750 (head of household). The large standard deduction means many moderate earners pay relatively little Louisiana state tax compared with states like Arkansas or Florida (no state income tax).

Louisiana taxable income in this calculator

Louisiana taxable income is based on gross wages after pre-tax 401(k) and HSA contributions, minus the state standard deduction. This approach differs from states that tax federally taxable wages directly, such as Indiana.

Worked example: $65,000 salary, single, biweekly, 5% 401(k)

Consider a single Louisiana employee earning $65,000 per year, paid biweekly, contributing 5% to a traditional 401(k), with no dependents or health premium deductions:

1. Pre-tax 401(k): $65,000 x 5% = $3,250 per year
2. Gross after pre-tax: $65,000 - $3,250 = $61,750
3. Louisiana taxable income: $61,750 - $12,875 (standard deduction) = $48,875
4. Louisiana state tax: $48,875 x 3% = $1,466.25 per year
5. FICA: Social Security and Medicare on the full $65,000 gross (401(k) does not reduce FICA wages)
6. Estimated net per paycheck: About $1,926.20 biweekly after all withholdings

Louisiana vs. neighboring state tax burdens

Louisiana sits among states with varied tax policies. Compare your salary against Arkansas (progressive rates), Florida (no state income tax), and Alaska (no state income tax). Running the same inputs through each state calculator reveals how relocation affects your monthly budget.
