What we do not model
For Louisiana: Taxable income starts from federal taxable income (after the federal standard deduction). Louisiana parishes and cities levy local income taxes. The figures above exclude local and municipal income taxes, tax credits, itemized deductions, phase-outs, alternative minimum tax, state disability insurance, and the Form W-4 details that change real withholding. They are an estimate, not tax advice — see the full disclaimer for what the model does and does not cover.
Common questions
- How does Louisiana income tax work?
- Louisiana uses a single flat rate of 3% on its own taxable income, after a standard deduction of $12,875 for single filers or $25,750 for married couples filing jointly. There are no brackets to climb, so every additional dollar is taxed at the same rate.
- What is the top Louisiana income tax rate?
- The top Louisiana rate is 3%, and it only applies to income above the highest bracket threshold shown above — not to your whole salary. The rate on your first dollars is 3%.
- What is the Louisiana standard deduction for 2026?
- $12,875 for single filers and $25,750 for married couples filing jointly; there is no separate dependent exemption. Taxable income is what remains after that deduction, and it is what the brackets are applied to.
- What is the take-home pay on $100,000 in Louisiana?
- For a single filer paid biweekly with no 401(k) deferral and no health premiums, a $100,000 salary in Louisiana leaves $2,944.86 per paycheck — $76,566.25 a year, an effective rate of 23.4% after $13,170 of federal income tax, $2,614 of Louisiana tax and $7,650 of FICA.
- Do remote workers pay Louisiana income tax?
- A Louisiana resident is generally taxed by Louisiana on wages earned anywhere, including wages for a remote job whose employer sits in another state. Days worked physically outside Louisiana can matter in some cases, and a non-resident working in Louisiana is generally taxed on income earned here. Nothing here is tax advice — the details depend on your situation.
- Does Louisiana have local income taxes?
- Taxable income starts from federal taxable income (after the federal standard deduction). Louisiana parishes and cities levy local income taxes. This calculator does not model that layer — treat the number above as state plus federal only.
