Louisiana Tax Tables
Louisiana Tax Tables provide a complete reference of how state income tax is calculated for each supported year. These tables summarise the official rules issued by the Louisiana Department of Revenue and present them in a clear structure that matches the calculations used in our Louisiana Tax Calculator. They are useful for checking withholdings, estimating liability, reviewing historical tax years and understanding how state policy shapes taxable income.

Each page shows the brackets or flat tax rate, deduction amounts, credit structures, withholding guidance and any year-specific updates published by the Louisiana Department of Revenue. You can also access the matching Louisiana Tax Calculator for precise calculations for that year.
How Louisiana Calculates Income Tax
Louisiana uses a progressive tax system where income is divided into brackets and each portion is taxed at its marginal rate. These rules determine how wages and other taxable income are assessed for Louisiana returns, with updated tables released each year to reflect legislation and inflation changes. For a broader explanation of how tax tables work, see our Tax Tables guide.
Certain jurisdictions within Louisiana also levy local or county income taxes. These appear in the annual state tax tables and may affect residents, part-year residents or nonresidents depending on local rules.
Louisiana supports resident, nonresident and part-year filing rules. The tax tables help clarify which thresholds apply when income is earned both inside and outside the state.
What Is Contained in the Louisiana Tax Tables?
Each tax-year page provides a structured summary of the components Louisiana uses to calculate individual income tax. While details vary by year, the state tax tables generally include the following elements:
- State tax brackets and marginal rates for each filing status.
- Standard deduction amounts for each filing status.
- Itemized deductions where permitted under Louisiana law.
- Dependent and family-related credits including any child-based or filer-based reductions.
- Retirement income rules including partial or full exemptions for pensions or Social Security.
- State withholding tables used by employers for payroll calculations.
Together, these elements provide a transparent breakdown of how Louisiana calculates tax for each year. This structure helps taxpayers review year-to-year changes, employers validate payroll withholding and financial planners analyse how Louisiana’s rules differ from federal requirements. All values shown in our Louisiana Tax Tables match the official figures published by the state.
