Louisiana sales tax is not one tax. It is a collection of taxes imposed at the state level and by 64 parishes, each with its own rates, rules, and filing requirements. For small business owners, the complexity is real: the combined rate in one parish can be more than double the rate in another. A seller in Baton Rouge faces a different compliance burden than a seller in Lafayette.
This guide explains how Louisiana sales tax works, what triggers the obligation to collect, how to register, how to file, and how to stay compliant. It is written for small business owners and operators who need a practical reference, not a legal treatise.
Louisiana sales tax rates at a glance
Louisiana’s sales tax system has two layers:
| Layer | Rate range | Who imposes it |
|---|---|---|
| State sales tax | 4.45% | Louisiana Department of Revenue (LDR) |
| Local sales tax | Up to 7% | Parishes, municipalities, and special districts |
| Combined rate | 4.45% – 11.45% | State + local |
The combined rate varies widely by location. Here are a few examples:
| City / Parish | Combined sales tax rate |
|---|---|
| Sterlington | 10.95% |
| Lake Charles | 10.2% |
| Baton Rouge | 9.95% |
| New Orleans | 9.45% |
| Lafayette | 9.45% |
| Shreveport | 9.05% |
A purchase of $100 in New Orleans is taxed at $9.45. The same purchase in Sterlington is taxed at $10.95. The difference is not the state rate — that is constant at 4.45%. The difference is the local rate, set by each jurisdiction.
What triggers Louisiana sales tax nexus
You must collect Louisiana sales tax if you have nexus with the state. Nexus is the legal connection between your business and the state that creates a tax obligation.
Louisiana recognizes several types of nexus:
| Nexus type | Threshold |
|---|---|
| Physical presence | Any physical presence in Louisiana — office, warehouse, employee, inventory, or property |
| Economic nexus | $100,000 in gross annual revenue or 200+ separate transactions into Louisiana in the current or previous calendar year |
| Affiliate / click-through nexus | $50,000 in sales from referrals through Louisiana affiliates |
| Inventory or property in state | Any inventory stored in Louisiana, including in a third-party fulfillment center |
The economic nexus threshold is the most common trigger for remote sellers. If you sell online and ship into Louisiana, you may owe sales tax even if you have no physical presence in the state.
Once you meet a threshold, you must register for a Louisiana sales tax certificate and begin collecting applicable state and local sales taxes.
Remote sellers and marketplace facilitators
Louisiana requires remote sellers with more than $100,000 in sales into the state to register and collect. Marketplace facilitators — platforms like Amazon, Etsy, or eBay that handle sales on behalf of third-party sellers — are also required to collect and remit Louisiana sales tax on behalf of their sellers.
If you sell through a marketplace, confirm whether the marketplace collects on your behalf. If it does, you may not need to collect separately on those sales — but you still need to track your direct sales and register if you meet the threshold.
How to register for Louisiana sales tax
Registration is handled through the Louisiana Department of Revenue. The process has three main steps:
Step 1: Register with the Secretary of State (if required)
If you are forming an LLC, corporation, or partnership, you must register your entity with the Louisiana Secretary of State. This is a separate process from tax registration. The Secretary of State issues your entity formation documents; the Department of Revenue issues your tax account numbers.
Step 2: Register for sales tax with LDR
Visit the Louisiana Department of Revenue website and create a business account through geauxBiz.com. You will need:
- Your Federal Employer Identification Number (FEIN)
- Your Louisiana Secretary of State entity number (if applicable)
- Business address and contact information
- Description of your business activities
- Estimated monthly sales tax liability
Once approved, you will receive a Louisiana Sales Tax Certificate of Registration. This certificate authorizes you to collect and remit sales tax. There is no fee to obtain the certificate.
Step 3: Register with local jurisdictions
In addition to the state registration, you may need to register separately with local taxing authorities. Louisiana’s local government structure is based on parishes, not counties. Each parish has its own sales tax rules, and some municipalities impose their own taxes on top of the parish rate.
For businesses in East Baton Rouge Parish, for example, the Revenue Division of the City-Parish Finance Department handles local sales tax registration. The parish also requires an occupational license, which is a separate requirement from the sales tax certificate.
The safest approach is to confirm local requirements with each parish where you have nexus. The Louisiana Association of Tax Administrators maintains a list of local taxing authorities.
Filing Louisiana sales tax returns
Louisiana sales tax returns are filed through Parish E-File, the state’s online portal for state and local sales tax. The portal allows you to file returns for multiple jurisdictions in one place.
Filing frequency
LDR assigns your filing frequency based on your estimated tax liability:
| Filing frequency | When assigned | Due date |
|---|---|---|
| Monthly | Higher tax liability | 20th of the following month |
| Quarterly | Lower tax liability | 20th of the month after quarter end |
| Annual | Very low liability (some cases) | January 20 |
If you are unsure of your assigned frequency, check your LDR account or the return setup screen in Parish E-File.
Filing steps
- Log in to Parish E-File at
parishe-file.revenue.louisiana.gov - Select the filing period
- Select the return type (multi-jurisdiction or single jurisdiction)
- Select the location
- Complete the return with gross sales, taxable sales, and tax due
- Review the summary
- File the return and receive a confirmation number
If you have zero sales in a period, you must still file a $0 return. Failure to file — even with no tax due — can result in penalties.
Payment
Payments can be made electronically through Parish E-File using your bank account information (routing and account number). You can also pay by credit card through the LDR website. Do not send cash.
Penalties and interest
Louisiana imposes penalties for late filing and late payment:
| Penalty type | Amount | Cap |
|---|---|---|
| Late filing | 5% of tax due for the first 30 days, plus 5% for each additional 30 days | 25% of tax due |
| Late payment | 0.5% of unpaid tax per 30 days | 25% of unpaid tax |
| Interest | Varies based on LDR’s published rate | Accrues from the original due date |
The late filing and late payment penalties are calculated separately. The combined total cannot exceed 25% of the tax due. Interest continues to accrue until the balance is paid in full.
If you cannot file by the due date, you can request an extension of up to six months. An extension does not relieve you of the obligation to pay the tax by the original due date. If you owe tax and do not pay it by the original due date, penalties and interest will apply even if you have an extension to file.
Exemptions and special rules
Not everything is taxable in Louisiana. Key exemptions include:
- Most non-prepared food and groceries: Exempt from state sales tax but may be taxable locally.
- Prescription drugs: Exempt from state sales tax.
- Utilities (water and electricity): Exempt from state sales tax.
- Separately stated shipping charges: Generally exempt from state sales tax. If shipping is included in the item’s price, it is taxable.
- Digital products and SaaS: Taxable in Louisiana. This includes software, ebooks, music, and software-as-a-service.
- Professional services: Generally not taxable. Repair services, telecommunications, and utilities are taxable.
Louisiana is a destination-based sales tax state. Sales tax is determined by where the customer receives the product or service, not where the seller is located. This matters for remote sellers: you collect based on the shipping address, not your business address.
Louisiana is not a Streamlined Sales Tax state. It does not participate in the Simplified Sellers Use Tax program that some states offer for remote sellers.
Sales tax vs. occupational license
Small business owners often confuse two different requirements:
| Requirement | What it is | Where to get it |
|---|---|---|
| Sales Tax Certificate | Authorizes you to collect and remit sales tax | Louisiana Department of Revenue |
| Occupational License | Local business license to operate within a parish or municipality | Parish or city finance department |
You need a sales tax certificate if you sell taxable goods or services. You need an occupational license to operate a business within a specific jurisdiction. These are separate requirements, and you may need both.
In East Baton Rouge Parish, the occupational license is issued by the City-Parish Finance Department Revenue Division. The fee ranges from $25 to $50 depending on the jurisdiction and business type. You will need picture identification and your corporate charter (if incorporated) to apply.
Audit process
If LDR selects your business for a sales tax audit, the process follows these steps:
- Notice of intent to audit: LDR sends a formal notice specifying the records required and a proposed audit date.
- Preparation: Gather financial records, invoices, tax returns, and exemption certificates.
- Audit review: An auditor reviews your records to verify that you collected and remitted sales tax accurately.
- Audit report: The auditor issues a report outlining discrepancies, additional tax owed, or refunds due.
- Payment or appeal: If discrepancies are found, you can pay or enter a payment plan. If you disagree, you can appeal to LDR, then to the Louisiana Board of Tax Appeals, and ultimately to Louisiana District Court.
The best defense against an audit is clean records. Keep exemption certificates for all wholesale or resale transactions, and reconcile your sales tax returns with your accounting records regularly.
How to stay compliant
Five practices keep most Louisiana small businesses out of trouble:
- Register before you sell. If you have nexus, register and start collecting before your first taxable sale. Retroactive registration creates back tax liability.
- Know your local rates. Do not assume the rate in one parish is the rate in another. Use the Louisiana Sales and Use Tax Rate Lookup tool or consult your Parish E-File account.
- File on time, even if you owe nothing. A $0 return is still a return. Missing it triggers penalties.
- Keep exemption certificates. If you sell to a reseller or a tax-exempt organization, keep the documentation.
- Work with a CPA or tax professional. Louisiana sales tax is complex enough that professional guidance pays for itself. A CPA can help with registration, filing, and audit defense.
The Louisiana Department of Revenue publishes tax forms, rate tables, and policy documents on its website. Parish E-File includes a library of video tutorials covering account setup, return filing, and payment.
