Planning estimate for a single filer earning $52,800 (Louisiana median household income in LevyIO's state dataset) who removes $5,000 from taxable income. Federal tax uses the 2026 IRS brackets after the $16,100 standard deduction; LA tax uses the state brackets in LevyIO's dataset and assumes the state follows the federal treatment.

|---|---|---|---|---|
| 10% | $16,100 - $28,500 | 3% | 13% | $130 |
