Louisiana (LA) Tax & Business Landscape
Key Louisiana Tax Numbers (Post-2025 Reform). Personal income tax: Louisiana's 2025 tax reform moved the state from a graduated structure (1.85% / 3.5% / 4.25%) to a flat 3% personal income tax effective for tax year 2025. Corporate income tax: simplified to a flat 5.5%. Sales and use tax: 5% state (raised from 4.45% in 2025), plus parish/local; combined rates approximately 10% in many areas — among the highest combined sales tax rates in the U.S. Estate tax: none. Pass-through entity (PTE) elective tax: rate matches personal IT (3% post-reform), available since tax year 2019 — among the earliest state PTEs in the country. Louisiana Motion Picture Production Tax Credit: 25% transferable base credit on qualified production expenditures, plus 15% for Louisiana resident labor and 5% for productions outside the New Orleans metro.
Filing Mechanics. Individuals file Form IT-540 (residents) or IT-540B (nonresidents and part-year residents) by May 15 — NOT April 15 (one of the few states with a different individual income tax deadline). C-corporations file Form CIT-620 (Corporation Income and Franchise Tax). Partnerships file Form IT-565; S-corps file Form CIFT-620. PTE election is made on partnership/S-corp returns. Returns are administered by the Louisiana Department of Revenue. We use those mechanics to build a filing calendar and document request list for oil and gas industry professionals, petrochemical workers, film and entertainment professionals, real estate investors, restaurant and hospitality operators before deadlines compress the planning options.
Louisiana's Civil-Law Legal System. Louisiana is the only U.S. state with a civil-law legal system (descended from French and Spanish legal traditions, not English common law). This affects estate planning materially: Louisiana has unique forced heirship rules requiring a portion of an estate to pass to certain forced heirs (descendants under 24 or with permanent disabilities), usufruct and naked ownership concepts, community property, and unique succession procedures. Standard out-of-state wills and trusts may not work as expected in Louisiana. We coordinate with Louisiana succession attorneys for civil-law-compliant planning.
Louisiana Economy & Who We Serve. Louisiana's economy is anchored by oil and gas (Gulf of Mexico offshore; the Haynesville Shale; the Mississippi River refining and petrochemical corridor), petrochemicals (Shell, ExxonMobil, Dow, Marathon along "Cancer Alley"/the chemical corridor), LNG export (Cheniere's Sabine Pass; Cameron LNG — Louisiana is now the largest U.S. LNG export hub), shipping/maritime (Port of South Louisiana — the largest tonnage port in the U.S.; Port of New Orleans), tourism (New Orleans, Mardi Gras, jazz, Cajun culture, food), film and entertainment ("Hollywood South" — supported by the LA Film Tax Credit), seafood (shrimp, crawfish, oysters), agriculture (rice, sugarcane, soybeans, cotton), and a growing tech and aerospace sector. Our typical LA clients include oil and gas industry professionals, petrochemical workers, film and entertainment professionals, real estate investors, restaurant and hospitality operators, and high-net-worth families navigating Louisiana's unique civil-law estate planning.

Louisiana CPA — Frequently Asked Questions
Do I need a Louisiana-licensed CPA?
CPA mobility often allows an out-of-state CPA in active good standing to serve Louisiana clients, but the right answer depends on the engagement type. For oil and gas industry professionals, petrochemical workers, film and entertainment professionals, real estate investors, restaurant and hospitality operators, we confirm whether the work is tax, advisory, attest, employee-benefit-plan, or state-sensitive before accepting the engagement.
What is Louisiana's income tax rate, and when is the LA return due?
Following Louisiana's significant 2025 tax reform, the state moved from a graduated personal income tax (1.85% / 3.5% / 4.25%) to a flat 3% personal income tax effective for tax year 2025. Corporate income tax was similarly simplified to a flat 5.5%. Importantly, Louisiana's individual income tax return (Form IT-540) is due May 15 — NOT April 15. This is one of the most commonly missed filing deadlines for new Louisiana residents.
How does the Louisiana Film Tax Credit work?
Louisiana's Motion Picture Production Tax Credit is one of the most established film incentives in the country — a 25% transferable credit on qualified Louisiana production expenditures, plus an additional 15% for Louisiana resident labor and 5% for projects shot outside the New Orleans metropolitan area. The credit is freely transferable, creating an active secondary market where productions sell credits to LA taxpayers (typically at 88-92 cents on the dollar). We help production companies claim the credit and individual LA taxpayers purchase credits to reduce state tax liability.
Does Louisiana have a SALT-cap workaround?
Yes. Louisiana was actually one of the first states to enact a Pass-Through Entity Tax — effective for tax years beginning on or after January 1, 2019. Eligible S-corps and partnerships pay an entity-level tax tracking the personal income tax rate (3% post-2025 reform), and members receive a corresponding credit on Form IT-540.
Louisiana has civil law (descended from French/Spanish), not common law. How does that affect my estate planning?
Louisiana is the only U.S. state with a civil-law legal system, descended from French and Spanish legal traditions rather than English common law. This affects estate planning materially: Louisiana has unique "forced heirship" rules requiring that a portion of an estate pass to certain forced heirs (descendants under 24 or with permanent disabilities); usufruct and naked ownership concepts; community property; and unique succession procedures. Standard out-of-state wills and trusts may not work as expected in Louisiana. We coordinate with Louisiana succession attorneys for civil-law-compliant planning.
What special tax issues apply to Louisiana oil and gas operations?
Louisiana's oil and gas industry — anchored in the Gulf of Mexico, the Mississippi River industrial corridor, and the Haynesville Shale — faces specialized issues: severance tax (state mineral revenue tax), royalty interest and working interest accounting, intangible drilling cost (IDC) federal deductions, depletion (cost vs. percentage), Louisiana sales/use tax exemptions for qualified industrial users, and Louisiana Industrial Tax Exemption Program (ITEP) property tax abatements. We support Louisiana operators, royalty owners, and oilfield services companies with these specialized accounting and tax issues.
Do you serve Louisiana clients outside New Orleans?
Yes. Our practice is virtual-first, so we serve clients across all of Louisiana — including Baton Rouge (state capital; LSU; petrochemical), Shreveport, Metairie, Lafayette (Cajun country; oil and gas), Lake Charles (LNG; petrochemical), Bossier City, Kenner, Monroe, Alexandria, the Mississippi River industrial corridor, Cajun country, the Gulf Coast, and every Louisiana parish.
