Louisiana state income tax rate 2027.
Louisiana’s flat rate from the official source, with the 2026 figures and a labelled projected 2027 column.
Short answer: Louisiana taxes wages at a flat 3% for 2026 (a single bracket for single and joint filers). No different 2027 schedule is enacted yet, so the 2027 column carries the 2026 schedule forward and is labelled projected.

The Louisiana schedule
La. R.S. 47:32(A) on legis.la.gov: 'computed at the rate of three percent on net income'; LDR FAQ: 'For taxable periods beginning on or after January 1, 2025, the individual income tax rate is a flat 3%.' Flat rate, no brackets.
Single filers
| Taxable income | Rate, 2026 | Rate, 2027 (projected) |
|---|---|---|
| All taxable income | 3% | 3% |
Joint filers
| Taxable income | Rate, 2026 | Rate, 2027 (projected) |
|---|---|---|
| All taxable income | 3% | 3% |
Deductions, exemptions and local tax
Louisiana’s standard deduction, exemption and credit amounts are not stated here because they were not read from the Louisiana tax agency’s own pages on November 9, 2026. Use the state’s current return instructions. None of them is modelled.
None; Louisiana has no local income tax.
What changes in 2027 (projected)
R.S. 47:32 has no later step-down, so 2027 is a projection at 3% under the current text.
The 2027 column above carries the 2026 schedule forward. That is a projection, not an enacted 2027 schedule, and it is labelled that way wherever it appears.
Worked example (2026 schedule)
A single filer with $80,000 of Louisiana taxable income owes $2,400 under the 2026 schedule, an effective rate of 3.00% and a marginal rate of 3%. A joint filer with $150,000 of Louisiana taxable income owes $4,500 under the 2026 schedule, an effective rate of 3.00% and a marginal rate of 3%. The 2027 projection for the same incomes is the same dollar amount ($2,400 and $4,500) because the 2026 schedule is carried forward.
Common mix-ups
- Louisiana still has 1.85%/3.5%/4.25% brackets. The graduated brackets were repealed by Acts 2024, 3rd Ex. Sess., No. 11 (eff. Dec 4, 2024); the tax is a flat 3% from 2025.
- The flat tax starts in 2026 or 2027. LDR states the flat 3% applies to taxable periods beginning on or after Jan 1, 2025.
- Joint filers have different rates. One 3% rate applies to all filers.
Method
The tool applies each bracket rate only to the slice of income inside that bracket, adds the slices and divides by income for the effective rate; the marginal rate is the rate of the bracket that contains your income. The 2027 line uses the 2026 schedule and is shown as projected. Nothing you type is sent to our servers; the maths runs in your browser.

Not legal or tax advice
Rates change and this is an unofficial guide, not run by any state tax agency; any 2027 figure that is not enacted is a projection. Nothing you type is transmitted anywhere. Confirm with the Louisiana tax agency or a tax professional before you file.
