Louisiana Sales Tax for New Businesses: State 5% Plus Parish Tax

If you're starting a business in Louisiana that sells taxable goods or services, you'll need to understand the state's sales tax system and register with the appropriate agencies. Louisiana's sales tax structure combines a state rate with local parish and municipal taxes. The process involves registering with both the Louisiana Department of Revenue and your parish, and understanding the total tax rate your business must collect.

Louisiana Sales Tax Rate: 5% Statewide, Rising to Parishes

The Louisiana state sales tax rate is 5% as of January 1, 2025. This rate applies through December 31, 2029, and then drops to 4.75% in 2030 under a 2024 tax reform. The 5% state rate is fixed, but the total Louisiana sales tax rate your business must collect varies by parish and municipality.

Most parishes impose additional local sales taxes that stack on top of the state rate. For example, New Orleans imposes a 4.75% local sales tax, bringing the total sales tax rate in that city to 9.75%. Other parishes vary. You must collect the combined state and local rate at the address where the sale is made. This is why understanding your specific location matters when you start a business in Louisiana.

Digital products became taxable as of July 1, 2022, and remain taxable. If you sell digital goods, subscriptions, or digital services, you must register for sales tax and collect the full state plus local rate.

Parish and Local Taxes: You Collect Both

Louisiana's sales tax system does not separate state and local collection in the way some states do. Your business must collect the combined rate at the point of sale. The state 5% goes to the state; the parish and local portions go to those jurisdictions. Many parishes and municipalities also levy local occupational license taxes, which are separate from sales tax and depend on where your business operates.

You can find your parish's sales tax rate and requirements by contacting your parish tax assessor or the parish clerk of court. Since rates vary significantly between parishes, always confirm the correct rate for your operating location before you begin collecting.

Register for Louisiana Sales Tax: A Two-Part Process

Registering for Louisiana sales tax is not a single transaction. You must register with two separate agencies:

1. Louisiana Department of Revenue (State Registration)

First, register with the Louisiana Department of Revenue using the LaTAP system (Louisiana Tax and Permit System). This is the state's online portal for business tax registrations. Visit https://revenue.louisiana.gov/businesses/general-resources/business-registration/ to begin.

When you register with the Department of Revenue, you will receive your Louisiana Revenue Account Number (also called your sales tax account number). This is your state sales tax ID. The Revenue Account Number is unique to your business and is used on all state sales tax returns and correspondence with the Department of Revenue.

You will also receive a Louisiana Sales Tax Permit (technically called a Sales and Use Tax Account), which authorizes you to collect and remit sales tax on behalf of the state. This permit is a legal requirement. You must have it before you operate.

Registration with the Department of Revenue is free. The LaTAP system is the primary portal for state registrations, and the process is designed to walk you through all required state licenses and permits based on your industry and location.

2. Parish Registration (Local Registration)

Second, you must separately register with your parish. In Louisiana, each parish collects its own local sales tax and maintains its own registration system. You typically register with the parish clerk of court or the parish tax assessor depending on the parish. Some parishes use centralized portals; others require in-person filing.

When you register with your parish, you will receive a separate Louisiana Tax ID Number for the parish, in addition to your state Revenue Account Number. This is critical: the state ID and the parish ID are different and both are required.

Contact your parish clerk of court or tax assessor's office to learn how to register locally. Louisiana does not issue a single statewide business license, so most of your local compliance is parish-level, not state-level. A new business may also be subject to an occupational license tax from the parish or municipality, depending on your industry and location.

Sales Tax Registration Requirements: What You Need

To register for Louisiana sales tax, have the following ready:

• Your Federal Employer Identification Number (EIN) or Social Security Number if you are a sole proprietor.
• Your business name and structure (sole proprietor, LLC, corporation, etc.).
• Your business address and location in Louisiana where the taxable activities occur.
• Your anticipated monthly or annual sales volume, if known.
• A description of what you will sell or the services you will provide (important for determining if sales tax applies).
• Contact information for the person responsible for the business.

Some businesses are exempt from Louisiana sales tax collection. Common exemptions include certain nonprofits, sales for resale, and specific agricultural items. If you believe your business is exempt, the Department of Revenue can clarify before you register.

Sales Tax Filing and Payment: Combined Returns

Once registered, your business must file sales tax returns on a schedule determined by the state and your parish. Louisiana's sales tax system recently changed to allow a significant simplification: beginning January 2026, new or smaller businesses can file a combined state and local sales tax return instead of separate returns. This reduces paperwork and complexity.

With a combined return, you report all sales for the state plus local taxes on a single form. The Department of Revenue allocates the proceeds to the state and the parish. This option has made Louisiana sales tax more manageable for small businesses, though each parish and the state can impose conditions on who qualifies.

Filing frequency depends on your sales volume and prior tax history. Typically, sales tax is due monthly, with returns due on the 20th of the following month, but the Department of Revenue will confirm your specific filing schedule when you register.

You must keep detailed records of all sales, tax collected, and exemptions. Maintain records for at least three years. The state conducts audits and can assess penalties for late payment or inaccurate reporting.

Remote Sellers and Online Sales

If you are not physically located in Louisiana but sell goods or services to Louisiana customers, you may still be required to register and collect Louisiana sales tax. The state established the Sales and Use Tax Commission for Remote Sellers to simplify compliance for out-of-state sellers. Remote sellers can use this commission to register with the state and all parishes at once, rather than registering with the state and each individual parish separately.

If your business ships products to Louisiana or provides services to Louisiana customers, contact the Department of Revenue to determine your obligations. The rules depend on your sales volume and the nexus you have with Louisiana (whether you have property or employees there, for example).

Special Cases: Who Does Not Collect Sales Tax

Not all businesses collect Louisiana sales tax. Services not otherwise specifically taxed (consulting, accounting, legal services) are generally not taxable. Certain groceries and agricultural items are not taxed. Some businesses, such as certain nonprofits and educational institutions, are exempt. And businesses selling for resale (wholesale businesses selling to retailers) do not collect tax on those resale transactions if the buyer provides a valid resale certificate.

If you are unsure whether your business is required to collect sales tax, ask the Department of Revenue before you register. Collecting tax when you are not required to is a problem you want to avoid.

Getting Your Louisiana Sales Tax Permit: Timeline and Next Steps

Start the registration process now if you are opening a Louisiana business. Registering for Louisiana sales tax is the state and parish's way of tracking who is collecting tax and ensuring compliance. You cannot legally operate a taxable business without a sales tax permit. The state considers operating without registration a violation and can impose penalties.

Step 1: Register with the Louisiana Department of Revenue

Visit https://revenue.louisiana.gov/businesses/general-resources/business-registration/ to begin your state registration. The LaTAP system will ask about your business structure, location, and industry. You will receive your Louisiana Revenue Account Number and sales tax permit electronically.

Step 2: Register with your parish

After registering with the state, contact your parish clerk of court or tax assessor to register for the local component. Get your parish Louisiana Tax ID Number. Some parishes can provide this immediately; others may require an in-person visit or mail processing.

Step 3: Understand your filing obligations

Once registered, the state and parish will inform you of your filing frequency and deadline. Set up your business accounting to track taxable sales, tax collected, and exemptions from day one. Save all receipts and invoices. You will need this information for your returns and for audits.

Step 4: Collect and remit the correct combined rate

Your business must collect the full combined state and parish sales tax rate at the point of sale. As of 2025, your state portion is 5%. Your parish adds a local rate on top. Do not collect just the state rate; you must collect the full combined amount.
