Louisiana Income & Tax for eCommerce Businesses

At Tall Oak Advisors, Louisiana is one of the states we spend extra time preparing clients for — because the parish-level complexity is real, and the enforcement posture has been active since economic nexus was adopted.

💡 64 Parishes, All Different Rates: Louisiana has 64 parishes, each with its own sales tax rate, rules, and exemptions. Combined state and local rates can range from 5% (state only, in limited jurisdictions) to over 11% in some parishes and municipalities. There is no uniform local rate. Getting the rate right for every shipment requires address-level lookup. The Louisiana Sales and Use Tax Commission for Remote Sellers manages state and some parish taxes, but local compliance can still be complex.

Part 1: Louisiana Corporate Income Tax

Louisiana imposes a graduated corporate income tax on C corporations with nexus in the state. As of 2025, the rates are:

• 4% on the first $25,000 of Louisiana net income

• 5% on net income from $25,001 to $100,000

• 6% on net income from $100,001 to $200,000

• 7% on net income above $200,000

Louisiana has been actively reviewing its tax structure, with legislation in recent years aimed at flattening the rate structure. Verify current rates with the Louisiana Department of Revenue, as rate adjustments may have occurred. Pass-through entities — S corps, partnerships, LLCs — do not pay Louisiana corporate income tax at the entity level.

What Creates Louisiana Corporate Income Tax Nexus?

Louisiana uses standard physical and economic presence standards for corporate income tax nexus:

• Owning, leasing, or using property in Louisiana — including FBA inventory in Louisiana warehouses

• Having employees, agents, or representatives operating in Louisiana

• Doing business in Louisiana through regular, ongoing commercial activity

• Deriving income from Louisiana sources on a systematic basis

• Remote employees working from Louisiana addresses

PL 86-272 in Louisiana

Federal Public Law 86-272 protects C corporations from Louisiana's corporate income tax if their only Louisiana activity is soliciting orders for tangible goods approved and shipped from outside Louisiana. FBA inventory in Louisiana eliminates this protection. Louisiana follows standard PL 86-272 principles, though sellers with significant Louisiana economic activity should review their position carefully.

Part 2: Louisiana Sales Tax — The Commission and the Parishes

The Louisiana Sales and Use Tax Commission for Remote Sellers

Louisiana has a unique administrative structure for remote seller compliance: a dedicated Louisiana Sales and Use Tax Commission for Remote Sellers. Remote sellers register with this Commission rather than directly with the Louisiana Department of Revenue. The Commission administers the state rate and participates in parish-level remittance for participating parishes, simplifying — though not eliminating — the multi-parish compliance challenge.

Economic Nexus Threshold

Louisiana's economic nexus threshold is $100,000 in retail sales from Louisiana customers in the current or previous calendar year. Key details:

• Transaction count threshold: eliminated August 1, 2023 — revenue only

• Marketplace sales through certified facilitators are excluded from your individual threshold — if the marketplace is collecting Louisiana tax on those sales, they don't count toward your $100,000

• Registration window: register within 30 days of crossing the threshold; collection must begin no later than 60 days after exceeding the threshold

• Threshold based on current or prior calendar year

Louisiana Sales Tax Rates

Louisiana's state sales tax rate is 5% (effective January 1, 2025 — the rate was 4.45% before that, and legislative changes have adjusted it). On top of the state rate, each of the 64 parishes and many municipalities add their own levies:

• Parish rates: typically 2%–5%

• Municipal/city rates: additional 1%–3% in many incorporated areas

• Combined rates: 5%–11% across the state — New Orleans (Orleans Parish) typically around 9.45%; Baton Rouge area similar; rural areas lower

Louisiana is a destination-based state for remote sellers — charge based on the customer's delivery address. With 64 parishes and hundreds of municipalities all setting their own rates, address-level rate lookup is essential. Sales tax automation software is not optional for Louisiana — it's a necessity.

SaaS and Digital Products: Generally Not Taxable

Louisiana generally does not impose sales tax on SaaS or purely digital services at the state level. This is a notable exemption compared to states like Massachusetts and Washington. However, some parishes may have their own rules for digital products, so sellers of digital goods should verify local taxability as well as state treatment.

FBA Sellers and Louisiana

Amazon operates fulfillment center infrastructure in Louisiana. FBA inventory stored in Louisiana creates immediate physical nexus for both sales tax and corporate income tax, regardless of whether you've crossed the $100,000 economic nexus threshold. For FBA sellers, checking the Inventory Event Detail Report in Amazon Seller Central for Louisiana is the first step in assessing your exposure.

The Local Parish Compliance Challenge

Even with the Sales and Use Tax Commission simplifying remote seller registration, Louisiana's parish-level complexity remains significant. Some parishes have their own independent sales tax administrations. Exemptions that apply at the state level may not apply locally, and vice versa. Sellers shipping significant volume into Louisiana are strongly encouraged to use automated sales tax software and work with a Louisiana-familiar advisor to ensure local rates are correctly applied.

What About Sales Tax?

Louisiana's 5% state rate plus up to 6%+ in parish and city taxes — with combined rates regularly exceeding 10% — makes it one of the highest-effective-rate states in the country for consumer goods.
