Tax Year 2017 Louisiana Income Tax Brackets
|Tax Bracket||Tax Rate|
|Tax Bracket||Tax Rate|
Louisiana's income tax brackets were last changed six years prior to 2015 for tax year 2009, and the tax rates have not been changed since at least 2001.
Louisiana has three marginal tax brackets, ranging from 2% (the lowest Louisiana tax bracket) to 6% (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.
How do Louisiana tax brackets work?
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. The chart below breaks down the Louisiana tax brackets using this model:
|For earnings between $0.00 and $12,500.00, you'll pay 2%|
|For earnings between $12,500.00 and $50,000.00, you'll pay 4% plus $250.00|
|For earnings over $50,000.00, you'll pay 6% plus $1,750.00|
|For earnings between $0.00 and $25,000.00, you'll pay 2%|
|For earnings between $25,000.00 and $100,000.00, you'll pay 4% plus $500.00|
|For earnings over $100,000.00, you'll pay 6% plus $3,500.00|

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.

Louisiana Tax Deductions
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.

Louisiana Standard Deductions & Personal Exemption Amounts
In addition to marginal tax brackets, one of the major features of the Louisiana income tax is deductions. The three most common deductions encountered by taxpayers are the Louisiana Standard Deduction, the Louisiana Personal Exemption, and the Louisiana Dependent Deduction. The current values of these deductions for tax year 2015 are as follows:
|Standard Deduction (Single)||Standard Deduction (MFJ)||Personal Exemption||Dependant Exemption|
The standard deduction, which Louisiana does not have, is a deduction that is available by default to all taxpayers who do not instead choose to file an itemized deduction.
The Personal Exemption, which is supported by the Louisiana income tax, is an additional deduction you can take if you (and not someone else) are primarily responsible for your own living expenses. Likewise, you can take an additional dependent exemption for each qualifying dependent (like a child or family member), who you financially support.
The Federal income tax also has a standard deduction, personal exemptions, and dependant deductions, though they are different amounts than Louisiana's and may have different rules.
