Louisiana paycheck calculator, 2026
Louisiana withholding is computed from a formula built around personal exemptions rather than a straightforward bracket lookup, so the number of exemptions claimed on Form L-4 has an outsized effect compared with allowances in other states. Our 2026 Louisiana figures are still being cross-checked, so this page shows the rules and sources rather than a take-home estimate.
The Louisiana withholding rate, 2026
3.09%applied to taxable wages
Louisiana works this out from a formula rather than a bracket table, so the amount withheld depends on what your state form says as well as what you earn. These are the steps the calculation actually takes:
What the Louisiana withholding form asks for
| Field | What it does | Where it appears |
|---|---|---|
| L-4 standard deductions claimed | 0, 1, or 2; married employees claiming one receive one-half of the married deduction. | Louisiana Form L-4, Block A |
Notes and caveats
- The current DOR formula uses $12,875/$25,750 deductions; stale NFC uses $12,500/$25,000. The DOR amounts are encoded.

This is an estimate of payroll withholding, not tax advice, and not a prediction of your final tax bill. Withholding is what your employer sends in during the year; what you actually owe is settled when you file.
