Louisiana Income Tax Calculator
Louisiana income tax is calculated on your taxable income after deductions and exemptions. This calculator estimates your Louisiana state income tax liability for the current tax year. Enter your annual gross income, choose your filing status (single, married filing jointly, married filing separately, or head of household), and add any pre-tax deductions to see your estimated state tax, effective tax rate, and marginal bracket. Results update in real time as you adjust your inputs. The calculator covers Louisiana state income tax only; federal income tax, FICA payroll taxes, and any local income taxes your city or county imposes are separate. All rates and brackets are sourced directly from Louisiana Department of Revenue and are verified for the current tax year. Use this tool alongside the federal income tax calculator to see your combined total tax liability. Effective rate and marginal rate are both shown so you can evaluate the impact of additional income, filing status changes, or increased pre-tax contributions to a 401(k) or similar plan.

How Louisiana income tax works
Louisiana imposes a graduated individual income tax under Louisiana Revised Statutes 47:293. The rates shown are effective January 1, 2025, following a reduction enacted by Act 1 of the 2024 Third Extraordinary Legislative Session. Single filers and married filing separately face three brackets from 1.85% to 4.25%. Married filing jointly, head of household, and surviving spouse filers use doubled bracket thresholds at the same three rates. Louisiana's standard deduction is set by state law and does not conform to the federal standard deduction. Your result updates the page link, so you can copy a permalink to any calculation.
taxable income = gross income - standard deduction
state income tax = sum of (income in each bracket x bracket rate / 100)
