Louisiana Paycheck Calculator
Louisiana uses a personal exemption system rather than a standard deduction to reduce taxable income. Each personal exemption is worth $4,500, so a single filer with one exemption shelters the first $4,500 of income from state tax. After that, Louisiana's three brackets top out at 4.25%, which is on the lower end for southern states. But combined with federal income tax and FICA, the total bite from a Louisiana paycheck can still leave workers in New Orleans or Baton Rouge with noticeably less than their headline salary suggests.
This calculator puts all of it on the table. Enter your gross pay, select your filing status, adjust the number of personal exemptions to match your situation, add any deductions, and you'll get a clean line-by-line pay stub estimate per period. No guesswork, no surprises.
How Louisiana Income Tax Works
Louisiana's income tax has three brackets for single filers: 1.85% on the first $12,500 of taxable income, 3.5% on the next $37,500, and 4.25% on everything above $50,000. For married couples filing jointly, the thresholds double. Personal exemptions of $4,500 per person reduce taxable income before the brackets apply. Louisiana also allows a deduction for federal income taxes paid, which is a rare feature that lowers your state taxable income further.
The Federal Tax Deduction: Louisiana's Unique Feature
Louisiana permits taxpayers to deduct a portion of their actual federal income tax paid from their Louisiana taxable income. This deduction is capped and phased out at higher incomes, but for many middle-income workers it provides a real reduction. In practice, this means Louisiana's effective state tax rate is often lower than the headline bracket rates suggest. This calculator uses a simplified approach that doesn't fully model this deduction, so your actual state tax at filing may be slightly lower than the estimate shown.
No Statewide Local Income Tax
Louisiana does not have a statewide local income tax system. Some parishes have occupational license taxes on certain businesses, but wage earners in Louisiana generally face only federal and state income tax through payroll. New Orleans does not add an additional income tax on employees' wages beyond what the state collects.
The Formula and a Worked Example
Net Pay = Gross Pay per Period - Federal Tax - Social Security - Medicare - Louisiana Tax - Pre-Tax Deductions - Post-Tax Deductions
Example: $50,000 Salary, Single, One Exemption, Biweekly
Annual gross: $50,000. Biweekly gross: $1,923. Assume $120 per period pre-tax health premium, or $3,120 per year.
Federal taxable income: $50,000 minus $3,120 minus $14,600 standard deduction equals $32,280. Federal tax on $32,280 single is roughly $3,622 per year, or $139 per period.
Louisiana taxable income: $50,000 minus $3,120 minus $4,500 personal exemption equals $42,380. Tax: 1.85% on $12,500 equals $231, then 3.5% on $29,880 equals $1,046, total $1,277 per year, or $49 per period.
Social Security: $50,000 x 6.2% = $3,100 / $119 per period. Medicare: $50,000 x 1.45% = $725 / $28 per period.
Estimated net: $1,923 - $120 - $139 - $119 - $28 - $49 = approximately $1,468 per biweekly period.
Real Scenario: Healthcare Worker in Baton Rouge
A licensed practical nurse in Baton Rouge earning $46,000 is weighing whether to take a travel nursing contract that pays $62,000 but with no benefits. Running both scenarios through this calculator shows the $46,000 with $300 per period in pre-tax benefits nets around $1,360 biweekly. The $62,000 contract with no benefits and self-employment tax on top nets closer to $1,700 biweekly but requires paying for individual health coverage out of pocket. The difference narrows significantly once insurance costs are factored in, which is exactly the kind of comparison this calculator makes visible before a decision is made.
Ways to Reduce Your Louisiana Tax Bill
- Claim all your personal exemptions. Louisiana's exemption system rewards accurate claiming. A married couple with two dependents can shelter $18,000 from state tax through exemptions alone. Make sure your Louisiana withholding form reflects your actual household situation.
- Maximize pre-tax retirement contributions. Contributions to a 401(k), 403(b), or similar plan reduce your federal AGI, which flows into your Louisiana taxable income calculation. At Louisiana's top rate of 4.25%, a $5,000 contribution saves about $213 in state tax per year.
- File your Louisiana return to capture the federal tax deduction. The deduction for federal taxes paid is only realized on your annual Louisiana return. Your paycheck withholding doesn't account for it automatically. Filing your return correctly can produce a meaningful refund if your actual federal tax liability is significant.
- Update your Louisiana withholding after major income changes. Louisiana uses its own withholding form, the L-4. An outdated L-4 may not reflect your current exemption count or income level, leading to over or under-withholding throughout the year.

FAQs
What are Louisiana's income tax rates?
Louisiana has three income tax brackets for single filers: 1.85% on the first $12,500 of taxable income, 3.5% on income between $12,500 and $50,000, and 4.25% on all income above $50,000. For married couples filing jointly, the bracket thresholds double. Personal exemptions of $4,500 per person reduce taxable income before these rates apply.
What is Louisiana's personal exemption?
Louisiana uses personal exemptions rather than a standard deduction. Each personal exemption is worth $4,500. A single filer with one exemption reduces their Louisiana taxable income by $4,500. A married couple with two children would have four exemptions, sheltering $18,000 from state income tax before the brackets apply.
Does Louisiana allow a deduction for federal income taxes paid?
Yes. Louisiana allows taxpayers to deduct a portion of their federal income tax liability from their Louisiana taxable income. This is an unusual feature not found in most states. The deduction is claimed on the Louisiana annual return and is subject to income-based limitations. It effectively lowers Louisiana's real tax burden below what the headline rates suggest for many taxpayers.
Are there local income taxes in Louisiana?
No income tax is levied by Louisiana parishes or cities on employee wages. New Orleans, Baton Rouge, and all other Louisiana localities do not add a wage income tax on top of the state income tax. Your state and federal obligations are the only income tax layers on your paycheck.
Is retirement income taxed in Louisiana?
Louisiana exempts most public pension income, including state and local government retirement benefits and federal retirement income, from state income tax. Social Security is fully exempt. Private retirement plan distributions such as 401(k) or IRA withdrawals are generally taxable in Louisiana. The exemption for public pensions makes Louisiana a relatively favorable state for retired government workers.
How many exemptions should I claim on my Louisiana L-4 form?
Claim one exemption for yourself, one for your spouse if married, and one for each dependent child or other qualifying dependent. Each exemption is worth $4,500 off your Louisiana taxable income. Claiming too few results in over-withholding and a refund at filing. Claiming too many results in under-withholding and a potential balance due.
Does Louisiana tax tips and overtime pay?
Yes. Tips and overtime pay are treated as ordinary wages in Louisiana and are subject to both state and federal income tax. They're included in your gross income for Louisiana tax purposes and taxed at whatever bracket rate applies to your total taxable income for the year.
What is the Louisiana L-4 withholding form?
The L-4 is Louisiana's Employee's Withholding Exemption Certificate. You complete it when you start a new job in Louisiana. It tells your employer how many personal exemptions to apply when calculating your Louisiana state income tax withholding. You can update it at any time by submitting a new form to your payroll department, which takes effect on the next available pay period.
