How We Calculate the Result

We calculate your estimated Louisiana income tax by starting with your household income and subtracting any deductions and exemptions you enter — like your 401(k) contributions, IRA contributions, itemized deductions, and the number of personal exemptions. This gives us your taxable income.

Then, based on your filing status (single, married filing jointly, head of household, etc.), we apply the appropriate Louisiana tax brackets to calculate your tax:

  • For single filers, we apply 1.85% to the first $12,500, 3.5% to the next $37,500, and 4.25% to any income above $50,000.
  • For married couples filing jointly, we apply 1.85% to the first $25,000, 3.5% to the next $75,000, and 4.25% to any income over $100,000.

We also check whether your total income means you are required to file a federal return, based on your age and status. The tool then shows your estimated tax, effective tax rate, and a simple summary.


About Louisiana Income Tax

Louisiana has a progressive income tax system, which means the more you earn, the higher percentage you may pay in taxes. The state has three income tax brackets ranging from 1.85% to 4.25%. The exact amount of tax you pay depends on your filing status and taxable income (income after deductions and exemptions).

The state allows common deductions like 401(k) and IRA contributions, and offers a standard deduction or itemized deduction, whichever is higher. Louisiana also gives personal exemptions, which reduce your taxable income based on how many people you claim.

Unlike some states that have a flat tax, Louisiana adjusts your rate depending on how much you earn. It’s important for residents to file accurately to avoid penalties and get any refunds due.
