Louisiana taxes every dollar of state taxable income at a single rate of 3% — the 38th-highest top rate of the 51 jurisdictions. A single filer subtracts a $12,500 standard deduction before the rates are applied. Because the rate itself never changes, the effective rate moves only as those fixed dollar amounts shrink against a bigger salary — 2.06% on $40,000, rising to 2.75% on $150,000.

Assumptions
- Ordinary-income rate schedules only; no credits, AMT, capital-gains rates, QBI deduction or the 2025–2028 senior deduction.
- Standard deduction (plus additional amounts for 65+/blind) or your itemized figure, whichever is larger; no dependent-filer limitation.
- Married filing separately uses half the joint federal thresholds, per the IRS schedule, and the state's single-filer schedule.
- State tax uses each state's published rate schedule, standard deduction and personal exemption for the tax year shown with the results; the source URL and year for the state you pick are printed above the results, along with the simplifications made for that state.
- State figures exclude county, municipal and city income taxes, itemized deductions, retirement and capital-gains exclusions, and credits that phase out. Unlisted states fall back to the flat rate you enter.

How the neighbours compare
Louisiana borders 3 other jurisdictions. Moving across a state line is the one way most people can actually change which of these schedules applies to them, so here is the same income run through each of them.
| State | Rate structure | $50,000 | $75,000 | $150,000 |
|---|---|---|---|---|
| Louisiana | Flat 3% | $1,125 | $1,875 | $4,125 |
| Arkansas | 0% – 3.9% | $1,405 | $2,380 | $5,305 |
| Mississippi | 0% – 4% | $1,268 | $2,268 | $5,268 |
| Texas | No income tax | $0 | $0 | $0 |
State income tax on a single filer, after each state’s own deductions. Federal tax is identical wherever you live, so the difference between these rows is the whole difference.
What these Louisiana figures leave out
Recorded against Louisiana in the data rather than glossed over, because they change real bills.
- Louisiana replaced its graduated brackets with a flat 3% for tax years beginning on or after 1 January 2025.
- The standard deduction is doubled for joint filers and for heads of household. It is indexed to inflation, but Louisiana had not published a 2026 amount when this was compiled, so the 2025 amount is used.
