How it works
The calculator starts with your gross annual income and subtracts Louisiana’s 2026 standard deduction — $12,875 for single filers, $25,750 for married filing jointly (adjusted for inflation via the CPI-U). What’s left is your Louisiana taxable income, taxed at a single flat 3% rate — no graduated brackets, so your marginal rate equals your effective rate on taxable income. Your effective rate on gross income is lower because the deduction shields the first slice. Louisiana’s flat 3% has been in effect since January 1, 2025.
| Filing status | 2026 rate | Standard deduction |
|---|---|---|
| Single | 3% flat | $12,875 |
| Married filing jointly | 3% flat | $25,750 |
