Louisiana income tax brackets (single filer)
| Taxable income | Rate | Note |
|---|---|---|
| Over $0 | 3% | Single filer, taxable income |
Context
Louisiana's 2025 overhaul replaced its brackets with a flat 3% and a $12,500 standard deduction. Standard deduction / exemptions used here: $12,500 single, $25,000 joint. Married couples generally use doubled thresholds. City and county income taxes, where they exist, come on top.
What moves this number
Filing status and W-4 settings
Married filing jointly roughly doubles bracket widths and the standard deduction, so the same salary withholds very differently by status. Dependents, second jobs, and extra-withholding entries on the W-4 move every paycheck.
State and local taxes
Nine states levy no wage income tax while top marginal rates elsewhere exceed 10%, and cities like New York add their own layer. The same salary can differ by hundreds of dollars per month purely on location.
Pre-tax benefits
Traditional 401(k), HSA, and health premiums come out before income tax, shrinking both taxable income and the withholding on each check — a raise in contributions costs less take-home than the headline amount.
Methodology
Brackets from the state revenue department's 2025–2026 published schedules; effective rate computed with no pre-tax deductions or credits.
Assumptions and caveats
- Figures use current-year federal brackets and standard deductions; your actual withholding depends on your W-4 and state.
- Estimates exclude credits (Child Tax Credit, EITC), which can materially change the final number.
- This is educational arithmetic, not tax advice — confirm decisions with a tax professional.
