Louisiana Paycheck Calculator (Hourly)

How the Louisiana Paycheck Calculator Works

This Louisiana paycheck calculator hourly tool computes your take-home pay by subtracting federal income tax, Louisiana state income tax, and FICA (Social Security + Medicare) from your gross earnings. Louisiana uses a three-bracket progressive state income tax system with rates of 1.85%, 3.5%, and 4.25%, established under the state's 2024 tax reform legislation that simplified and restructured the previous bracket system.

The core formula:

Take-Home = Gross Pay - Federal Tax - State Tax - Social Security - Medicare $$P_{\text{net}}=P_{\text{gross}}-T_{\text{fed}}-T_{\text{LA}}-T_{\text{SS}}-T_{\text{Med}}$$

Annual gross is hourly wage multiplied by hours per week multiplied by 52 weeks. To convert between hourly and annual figures, see our salary calculator. Per-period pay divides the annual figure by 52, 26, 24, or 12 depending on your pay frequency.

Federal income tax follows progressive brackets from 10% on the first $11,925 of taxable income (single) up to 37% on income above $626,350. The standard deduction is $15,000 for single filers, $30,000 for married filing jointly, and $22,500 for head of household. Louisiana state income tax applies separately: 1.85% on the first $12,500 of taxable income, 3.5% from $12,500 to $50,000, and 4.25% above $50,000. Louisiana uses its own standard deduction of $4,500 for single and head of household filers and $9,000 for married filing jointly. Social Security tax is 6.2% on wages up to $176,100, and Medicare is 1.45% on all wages plus a 0.9% surtax above $200,000 single or $250,000 married.

Louisiana Hourly Paycheck Tax Breakdown

Louisiana's state income tax is a key component of the paycheck calculation for residents. The 2024 tax reform replaced the old four-bracket system with a cleaner three-bracket structure: 1.85% on the first $12,500, 3.5% from $12,500 to $50,000, and 4.25% above $50,000. Because the bracket thresholds are relatively generous compared to states like Alabama (where the top rate kicks in at just $3,000), many Louisiana workers earning moderate wages will pay effective state rates well below the top 4.25%. A worker earning $40,000 annually after the $4,500 standard deduction has $35,500 of taxable income, placing most of their earnings in the 1.85% and 3.5% brackets rather than the top rate.

Compared to its neighbors, Louisiana occupies a middle position. Texas charges no state income tax at all, making it the most favorable neighbor for wage earners. A worker earning $50,000 in Louisiana pays roughly $1,200 to $1,400 in state income tax, while the same worker in Texas keeps all of that. Mississippi imposes a graduated tax topping at 4.7%, slightly higher than Louisiana's 4.25% maximum. Arkansas charges up to 3.9%, making it somewhat comparable to Louisiana for most earners. The proximity to no-income-tax Texas is particularly relevant for workers in the Lake Charles refinery corridor and Shreveport area, where cross-border employment is common.

Louisiana's most distinctive feature is the federal income tax deduction on the state return. This provision allows residents to subtract their entire federal income tax liability from their Louisiana taxable income before computing state tax. For higher earners, this can meaningfully reduce the effective state rate. A worker paying $15,000 in federal income tax can subtract that amount from Louisiana taxable income, saving up to $637.50 at the 4.25% rate. Lower-income workers benefit less because they pay less in federal tax to deduct. This calculator does not apply the federal tax deduction, so your actual Louisiana liability may be lower than shown.

Your Louisiana paycheck deductions come from four sources:

• Federal income tax: Progressive brackets based on filing status and taxable income. See our income tax calculator for full-year estimates.
• Louisiana state income tax: Progressive brackets of 1.85%, 3.5%, and 4.25% with thresholds at $12,500 and $50,000.
• Social Security: 6.2% on wages up to $176,100 annually.
• Medicare: 1.45% on all wages, plus 0.9% surtax above $200,000 single or $250,000 married.

Variable Definitions

Hourly Wage: Your gross pay per hour before deductions. Louisiana follows the federal minimum of $7.25/hour. A petrochemical plant operator along the industrial corridor between Baton Rouge and New Orleans earning $28/hour grosses $58,240 annually, while a refinery process technician in Lake Charles earning $36/hour grosses $74,880. Port of New Orleans longshoremen and logistics workers commonly earn $22-$35/hour depending on experience and specialization, and offshore oil platform workers can earn $30-$50/hour with rotational schedules.

Hours per Week: Total regular hours. Full-time is 40. Offshore oil rig workers in the Gulf of Mexico often work 84-hour weeks on a 14-days-on, 14-days-off rotation, averaging 42 hours per week across the cycle. Healthcare workers at facilities like Ochsner Health in New Orleans or LSU Health in Shreveport may work three 12-hour shifts for 36 hours or pick up additional shifts for 48 hours. Enter your typical weekly figure. Overtime above 40 hours is paid at 1.5x under federal law.

Pay Frequency: Weekly (52 periods), biweekly (26), semi-monthly (24), or monthly (12). Most large Louisiana employers, including ExxonMobil Baton Rouge, Entergy Louisiana, CLECO, and major healthcare systems like Ochsner and Our Lady of the Lake, pay biweekly. State government employees and public school teachers are commonly paid semi-monthly or monthly. Port workers and construction tradespeople in the New Orleans metro often receive weekly pay.

Filing Status: Determines your federal and Louisiana standard deductions and bracket thresholds. A single filer working at the Sasol chemical complex in Lake Charles earning $55,000 has a federal standard deduction of $15,000 and Louisiana deduction of $4,500. Married filing jointly doubles the federal standard deduction to $30,000 and increases the Louisiana deduction to $9,000. Head of household, often used by single parents in Baton Rouge or New Orleans, provides $22,500 federally and $4,500 in Louisiana.

Pre-Tax Deduction: Percentage of gross pay contributed to 401(k), 403(b), or HSA. A chemical engineer at Dow Chemical in Plaquemine earning $85,000 who contributes 8% ($6,800) reduces both federal and Louisiana taxable income, saving roughly $1,496 federally (at 22%) and $289 in Louisiana (at 4.25%), for a combined tax savings of about $1,785 per year. Many Louisiana petrochemical employers offer generous 401(k) matching, making pre-tax contributions particularly valuable.

Worked Example 1: Louisiana Hourly Paycheck at $18/Hour

A single filer earning $18/hour, working 40 hours/week, biweekly pay, with a 5% pre-tax 401(k) contribution:

1. Annual gross: $18 x 40 x 52 = $37,440
2. Pre-tax deduction: $37,440 x 5% = $1,872
3. Taxable gross: $37,440 - $1,872 = $35,568
4. Federal taxable income: $35,568 - $15,000 (standard deduction) = $20,568
5. Federal tax: ($11,925 x 10%) + ($8,643 x 12%) = $1,192.50 + $1,037.16 = $2,229.66
6. Louisiana taxable income: $35,568 - $4,500 (LA standard deduction) = $31,068
7. Louisiana state tax: ($12,500 x 1.85%) + ($18,568 x 3.5%) = $231.25 + $649.88 = $881.13
8. Social Security: $35,568 x 6.2% = $2,205.22
9. Medicare: $35,568 x 1.45% = $515.74
10. Total deductions: $1,872 + $2,229.66 + $881.13 + $2,205.22 + $515.74 = $7,703.75
11. Annual take-home: $37,440 - $7,703.75 = $29,736.25
12. Biweekly take-home: $29,736.25 / 26 = $1,143.70

Worked Example 2: Louisiana Hourly Paycheck at $48/Hour

A married filing jointly filer earning $48/hour, working 40 hours/week, biweekly pay, with a 10% pre-tax 401(k) contribution:

1. Annual gross: $48 x 40 x 52 = $99,840
2. Pre-tax deduction: $99,840 x 10% = $9,984
3. Taxable gross: $99,840 - $9,984 = $89,856
4. Federal taxable income: $89,856 - $30,000 (married standard deduction) = $59,856
5. Federal tax: ($23,850 x 10%) + ($36,006 x 12%) = $2,385 + $4,320.72 = $6,705.72
6. Louisiana taxable income: $89,856 - $9,000 (LA married standard deduction) = $80,856
7. Louisiana state tax: ($12,500 x 1.85%) + ($37,500 x 3.5%) + ($30,856 x 4.25%) = $231.25 + $1,312.50 + $1,311.38 = $2,855.13
8. Social Security: $89,856 x 6.2% = $5,571.07
9. Medicare: $89,856 x 1.45% = $1,302.91
10. Total deductions: $9,984 + $6,705.72 + $2,855.13 + $5,571.07 + $1,302.91 = $26,418.83
11. Annual take-home: $99,840 - $26,418.83 = $73,421.17
12. Biweekly take-home: $73,421.17 / 26 = $2,823.89

This petrochemical corridor engineer takes home roughly 73.5% of gross. Louisiana's federal-tax deduction provision could reduce state tax by an additional $285 at this income level if elected on the state return.

Edge Cases and Advanced Scenarios

Social Security wage base cap ($176,100 in 2026): If you earn above $176,100 annually, Social Security tax stops at that threshold. An offshore drilling superintendent earning $250,000 pays SS tax capped at $176,100 x 6.2% = $10,918.20 rather than 6.2% of the full $250,000. The cap resets January 1 each year, meaning high earners see larger paychecks in the latter months after reaching the cap. This is particularly relevant in Louisiana's oil and gas sector, where senior engineers and platform managers frequently exceed the wage base.

Additional Medicare tax for high earners: Wages above $200,000 (single) or $250,000 (married) incur an extra 0.9% Medicare surtax. A senior petroleum engineer in Houston who lives in Louisiana and earns $280,000 filing single owes an additional ($280,000 - $200,000) x 0.9% = $720 in Medicare tax beyond the standard 1.45%. This surtax applies to wages only and is not split between employee and employer.

Federal tax deduction on Louisiana state return: Louisiana allows residents to deduct their entire federal income tax liability from their state taxable income. This creates a circular dependency: federal tax reduces state taxable income, but state tax (if itemized federally) could also affect federal liability. In practice, Louisiana computes the deduction based on actual federal tax paid. For a married couple with $120,000 in taxable gross income paying approximately $9,500 in federal tax, the federal tax deduction reduces Louisiana taxable income from $111,000 to $101,500, saving roughly $403 in state tax at the 4.25% rate. This benefit grows with income and is most impactful for workers in the federal 22% bracket and above.

Cross-border workers with Texas: Louisiana residents who commute to work in Texas owe Louisiana state income tax on their wages because Louisiana taxes residents on worldwide income regardless of where the work is performed. Conversely, Texas residents who commute into Louisiana for work at Lake Charles refineries or Shreveport employers do not owe Louisiana income tax as nonresidents if their employer properly withholds based on their Texas residency. Workers in the Beaumont-Port Arthur-Lake Charles corridor should verify their withholding status carefully, as incorrect state designation can lead to unexpected tax bills or overpayment.

What to Do with Your Louisiana Paycheck Result

• Compare your calculated take-home pay to your actual pay stub. Differences often come from health insurance premiums, union dues, or court-ordered garnishments not included here.
• Increase pre-tax 401(k) contributions to reduce both federal and Louisiana state tax. Every dollar contributed saves both your federal marginal rate and up to 4.25% in Louisiana state tax.
• Consider claiming the federal income tax deduction on your Louisiana return to lower your state liability. This is most valuable for workers in the federal 22% bracket or higher and can save hundreds of dollars annually.
• Review your Louisiana Form L-4 withholding alongside your federal W-4. Both can be adjusted independently when your circumstances change, such as marriage, a new child, or a significant raise.
• Use our federal income tax percentage calculator to see your effective federal rate and understand what share of your gross income goes to federal versus state taxes.
