Louisiana Paycheck Calculator 2026
Brand new 3% flat rate โ Louisiana overhauled its tax code in 2025. See how the reform affects your take-home pay.
How to Use This Calculator
Tab "Take-Home Pay"
Enter your gross annual salary, pay frequency, and filing status. The calculator deducts federal income tax, Louisiana's new 3% flat state tax, and FICA (Social Security + Medicare). Under "More options," add 401(k) contributions and health insurance premiums to see the impact of pre-tax deductions. You'll see your per-paycheck take-home and an annual summary with your effective tax rate.
Tab "Tax Breakdown"
A visual pie chart showing exactly where your money goes. You'll see four tax slices: federal income tax, LA state tax, Social Security, and Medicare. The chart also highlights that Louisiana's 3% flat rate is brand new โ replacing the old progressive 1.85%-4.25% system as of 2025.
Tab "Compare Filing Status"
See how your take-home pay changes across Single vs Married Filing Jointly vs Head of Household. The comparison shows federal tax, LA state tax, and total take-home for each status so you can see the exact dollar difference. Because LA now uses a flat rate, the state tax difference comes entirely from the standard deduction ($12,500 single vs $25,000 MFJ vs $18,750 HoH).
The Formulas
1. Start with gross annual salary
2. Subtract pre-tax deductions (401k, health insurance)
3. Subtract standard deduction ($15,750 Single / $31,500 MFJ / $23,500 HoH)
4. Apply progressive brackets: 10%, 12%, 22%, 24%, 32%, 35%, 37%
Louisiana State Tax (flat rate):
LA taxable income = Gross salary - LA standard deduction ($12,500 Single / $25,000 MFJ / $18,750 HoH)
LA tax = LA taxable income x 3.00%
No local income taxes apply anywhere in Louisiana.
FICA (Federal Insurance Contributions Act):
Social Security = 6.2% x min(Gross wages, $184,500)
Medicare = 1.45% x Gross wages
Additional Medicare = 0.9% x max(0, Gross wages - $200,000)
Take-Home Pay:
Net = Gross salary - Federal tax - LA state tax - Social Security - Medicare - Pre-tax deductions
All figures use 2026 IRS rates: SS wage base $184,500 (SSA), tax brackets from Rev. Proc. 2025-32, TCJA rates made permanent by OBBBA. Louisiana 3% flat rate per HB 1 (2024 Special Session), effective January 1, 2025.
Example
Marcus โ Software Developer in Baton Rouge, Louisiana
Filing Single. $80,000/year salary. Paid biweekly (26 paychecks). No pre-tax deductions.
LA taxable income = $80,000 - $12,500 = $67,500. LA tax = $67,500 x 3% = $2,025. Marcus keeps 78.5% of his gross salary. Under the old progressive system, he would have owed roughly $2,568 in state tax โ the reform saves him about $543/year. Compared to neighboring Texas (no state tax), the 3% rate costs $2,025 more โ but Louisiana's lower property taxes and cost of living can offset this.
