Louisiana offers a Research and Development Tax Credit program that rewards companies performing qualified research activities within the state. The credit is designed to encourage innovation across industries, from technology and life sciences to manufacturing, and it can be claimed in addition to the federal R&D credit.
The Louisiana credit is calculated as a percentage of qualified research expenses (QREs) incurred in the state:
Qualified expenses generally include wages paid to Louisiana-based R&D employees, supplies used in research, and 65% of contract research costs performed within the state.
To claim the credit, businesses must apply through Louisiana Economic Development (LED), which issues a credit certificate once eligibility is confirmed. Credits are refundable for small businesses (under 50 employees) and transferable for others.

It’s important to note that Louisiana’s R&D program is one of the few that allows refundability and transferability, making it especially useful for startups and growth-stage companies. Larger companies also benefit from meaningful offsets against state corporate income and franchise tax. Our team helps model eligibility, prepare documentation, and navigate the LED approval process so you can maximize every dollar of your benefit.
Starting in tax year 2025, businesses can now immediately deduct domestic R&D expenses in the year they occur instead of spreading deductions over five years. The bill also offers refund opportunities for small businesses and faster deduction schedules for larger companies.
If your business has $31 million or less in annual gross receipts, you may be able to:
File amended returns for 2022–2024 to get cash refunds for previously capitalized R&D costs
Deduct remaining unamortized R&D expenses faster starting in 2025
Apply your R&D credit against payroll taxes—up to $500,000 per year for qualifying startups
Yes. Eligible small businesses can retroactively deduct R&D costs from 2022–2024 and claim refunds. Even larger companies can accelerate the deduction of past R&D costs over one or two years starting in 2025.
No. The 15-year amortization rule for foreign R&D remains in place. The new immediate expensing option only applies to U.S.-based research and development.
Savings vary, but many businesses may recover hundreds of thousands of dollars through a combination of:
Full expensing of domestic R&D costs
Retroactive refunds for 2022–2024
Annual R&D tax credits (often worth 5–10% of qualifying expenses)
Startups with less than $5 million in annual revenue can use the R&D credit to offset payroll taxes—up to $500,000 per year—resulting in quarterly cash refunds, even without taxable income.
