Louisiana has three marginal tax brackets, ranging from 2.00% (the lowest Louisiana tax bracket) to 6.00% (the highest Louisiana tax bracket). Each marginal rate only applies to earnings within the applicable marginal tax bracket.

In Louisiana, different tax brackets are applicable to different filing types. Married couples filing their Louisiana income tax return jointly will usually have wider tax brackets than those filing separately or as an individual.

Technically, you don't have just one "tax bracket" - you pay all of the Louisiana marginal tax rates from the lowest tax bracket to the tax bracket in which you earned your last dollar. For comparison purposes, however, your Louisiana tax bracket is the tax bracket in which your last earned dollar in any given tax period falls.

You can think of the bracketed income tax as a flat amount for all of the money you earned up to your highest tax bracket, plus a marginal percentage of any amount you earned over that.

You can use the income tax estimator to the left to calculate your approximate Louisiana and Federal income tax based on the most recent tax brackets.

Keep in mind that this estimator assumes all income is from wages, assumes the standard deduction, and does not account for tax credits.

When calculating your Louisiana income tax, keep in mind that the Louisiana state income tax brackets are only applied to your adjusted gross income (AGI) after you have made any qualifying deductions.

Qualifying deductions might include an itemized deduction, the Louisiana standard deduction, exemptions for dependants, business expenses, etc.

Remember that Louisiana may have very different deduction laws from the Federal Income Tax, so you may have to write a whole new list of deductions for your Louisiana income tax return.
