How Louisiana Taxes Bonuses in 2025
Louisiana treats bonuses as supplemental income, distinct from regular wages. Starting January 1, 2025, the state implements a flat 3% individual income tax rate under House Bill 10 (HB10), replacing the previous tiered system. This shift simplifies taxation but impacts how bonuses are withheld.
Federal and State Tax Withholding
Bonuses are considered supplemental income by the IRS and are taxed differently than regular wages.
Federal Tax Rate: 22% flat tax on bonuses under $1 million; 37% for bonuses over $1 million.
Louisiana State Tax: Progressive tax rates ranging from 1.85% to 4.25%, depending on income.
FICA Taxes: 6.2% Social Security + 1.45% Medicare tax = 7.65% total.
Bonus Tax Withholding Methods
Percentage Method: A flat 22% federal tax is withheld, plus state and FICA taxes.
Aggregate Method: Bonus is combined with your regular paycheck, and total withholding depends on your income bracket.
Comparison to Pre-2025 Rules
Before 2025, Louisiana’s graduated rates ranged from 1.85% to 4.25%. A $5,000 bonus for a single filer earning $60,000 annually might have faced a 3.5% rate in 2024. Now, that same bonus incurs a consistent 3% tax, saving $25 in state taxes—a small but noticeable change.
1. Tax Rate Comparison: Pre-2025 vs. 2025
| Income Level | Pre-2025 Rate | 2025 Rate (HB10) | Change |
|---|---|---|---|
| Up to $12,500 | 1.85% | 3.00% | +1.15% |
| $12,501 - $50,000 | 3.50% | 3.00% | -0.50% |
| Over $50,000 | 4.25% | 3.00% | -1.25% |
| Example: A $5,000 bonus for someone earning $60,000 would be taxed at 4.25% before 2025 ($212.50), but only 3% in 2025 ($150), saving $62.50. | |||

Federal Tax Rules for Bonuses in 2025
The IRS governs federal taxation of bonuses, and these rules apply uniformly across states, including Louisiana. Employers choose between two methods to withhold federal taxes, affecting your take-home pay.
Percentage Method
The IRS sets a flat 22% withholding rate for bonuses paid separately from regular wages (37% if over $1 million). For a $2,000 bonus, $440 goes to federal tax, leaving $1,560 before state and other deductions.
Aggregate Method
If your bonus combines with regular pay, the employer uses your W-4 data to calculate withholdings. A $1,000 bonus added to a $3,000 biweekly paycheck totals $4,000. Using 2025 tax brackets, a single filer might see $514 withheld federally—more than the flat 22% due to bracket creep.
Social Security and Medicare
Bonuses also face 6.2% Social Security tax (up to $168,600 in 2025) and 1.45% Medicare tax. High earners above $200,000 may pay an additional 0.9% Medicare surcharge, totaling 2.35%.

Louisiana’s 2025 Tax Reform Impact
Louisiana’s special legislative session in November 2024 introduced sweeping changes effective 2025. These reforms reshape how bonuses fit into the broader tax picture.
Flat Tax Adoption
HB10’s 3% flat rate reduces tax liability for high earners. Previously, a $10,000 bonus atop a $100,000 salary faced 4.25% on most of it. Now, it’s 3%, saving $125 in state tax—a boon for professionals.
Sales Tax Trade-Off
To offset income tax cuts, Louisiana raises its sales tax from 4.45% to 5% through 2029 (then 4.75%). This indirectly affects bonus spending power, as goods and services cost more.
Business Implications
Corporations now face a 5.5% flat tax (HB2) and can elect 100% bonus depreciation, diverging from federal phase-outs (40% in 2025). This encourages investment, potentially increasing bonus pools.
Special Considerations for High-Income Earners
If your income including bonuses exceeds certain thresholds, you’ll face additional tax considerations in Louisiana:
Net Investment Income Tax
If your modified adjusted gross income exceeds $200,000 (single) or $250,000 (married filing jointly), you may owe an additional 3.8% Net Investment Income Tax on investment income.
Alternative Minimum Tax (AMT)
Large bonuses can trigger AMT liability, which recalculates your tax using different rules and rates. The AMT exemption amounts for 2025 are $83,300 for single filers and $129,400 for married couples filing jointly.
According to the Louisiana Department of Revenue’s 2024 Annual Report, nearly 15% of taxpayers receiving bonuses exceeding $50,000 triggered AMT considerations, resulting in higher effective tax rates than initially expected.

Timing Strategies for Louisiana Bonus Recipients
When you receive your bonus can impact your overall tax situation. Consider these timing strategies to potentially reduce your tax burden:
Defer to a Lower-Income Year
If you’re expecting a significant income change between tax years, you might benefit from:
- Requesting your bonus in January rather than December if you expect lower income next year
- Delaying the bonus if you anticipate retiring or taking unpaid leave the following year
- Accelerating the bonus if you expect a promotion or significant income increase next year
Retirement Plan Contributions
Louisiana residents can direct part or all of their bonuses into qualified retirement plans:
- 401(k) contributions: Up to $23,000 for 2025 ($30,500 if you’re 50 or older)
- Traditional IRA contributions: Up to $7,000 ($8,000 if you’re 50 or older)
These contributions can reduce your taxable income, potentially putting you in a lower tax bracket for both state and federal taxes.

Comparing Louisiana’s Bonus Tax to Neighboring States
Louisiana’s bonus tax rates are competitive compared to neighboring states:
- Texas: No state income tax on bonuses
- Arkansas: Up to 4.9% state tax on bonuses
- Mississippi: Up to 5% state tax on bonuses
This regional comparison shows Louisiana falls in the middle, offering more favorable bonus taxation than Arkansas and Mississippi but not as advantageous as Texas’s zero income tax policy.
According to tax analysis from TaxFoundation.org, Louisiana’s effective tax rate on supplemental wages ranks 23rd lowest among all states, making it relatively competitive nationally.
Planning Ahead: Expert Recommendations
To maximize your Louisiana bonus in 2025:
- Consult a tax professional: Before receiving a significant bonus, speak with a qualified tax advisor familiar with Louisiana tax law
- Adjust withholding: Temporarily adjust your W-4 withholding if you expect significant overwithholding
- Consider retirement contributions: Direct bonus money to tax-advantaged retirement accounts to reduce your taxable income
- Plan for estimated taxes: If your bonus is large enough to trigger underpayment penalties, make estimated tax payments
- Document everything: Keep clear records of bonus payments, withholding amounts, and any special arrangements with your employer
As noted in the Journal of Accountancy’s 2024 tax planning guide, “Strategic timing and allocation of bonus compensation can result in tax savings of up to 15% for high-income earners in states like Louisiana.”
