Most states keep sales tax fairly simple. You charge a state rate plus a local rate, and you file one return. Louisiana doesn’t work that way.
The state charges 5%. On top of that, parishes, cities, school boards, and special districts can each add their own tax, and those local rates go as high as 7%. As of July 1, 2026, Louisiana’s average combined rate was 10.13%, the highest in the country.
If you sell from one storefront, you can live with that. But once you start delivering to customers in other parishes, selling online, or providing taxable services around the state, it gets harder to know which rate to charge and who to pay. Here’s how it works and where businesses most often get it wrong.
Two layers of tax on every sale
The state portion is 5%, up from 4.45% before January 1, 2025. It’s scheduled to drop to 4.75% after December 31, 2029. You report and pay it to the Louisiana Department of Revenue (LDR).
The local portion is a different story. Each parish generally has a single local collector that handles the sales taxes for the parish, its cities, its school board, and any special districts. The rate depends on exactly where the sale happens. Two addresses in the same parish can have different rates if one is inside city limits or a special district and the other isn’t.
| Layer | Rate | Who collects it |
|---|---|---|
| State | 5% | Louisiana Department of Revenue |
| Local (parish, city, school board, and districts) | Varies, up to 7% | The local collector for each parish |
| Average combined rate | 10.13% |
The list of what’s taxable also grew in 2025. Software as a service, apps, e-books, streaming, digital games, and some information services are now taxable at both the state and local level. If you sell any of those, you may have a sales tax obligation you didn’t have two years ago.
Why parish lines matter
Louisiana generally taxes a sale where the customer receives it (La. R.S. 47:301.4). That one rule is behind most of the confusion.
If the customer picks up at your location, you charge the rate at your address, and the local tax goes to your parish.
If you deliver, the sale belongs to the delivery address. You charge the local rate where the customer takes the goods, and that local tax goes to the parish where the delivery address sits. That means you may need to register and file with that parish’s collector too, so check with each parish you deliver into.
Taxable services and digital products follow a similar rule. They’re taxed where the customer receives them. For local tax, software and digital products used in more than one parish can be split among those parishes based on the number of users or licensees in each, if the seller knows those numbers at the time of sale.
Leased equipment works a little differently. For local tax, the first payment is taxed where the customer takes possession, and later payments are taxed where the equipment is mainly located.
A quick example
Say a contractor supply company sells $20,000 of materials to a builder. The rates below are made up, but the math is how it works.
| What happens | Rate charged | Tax | Who gets the local tax |
|---|---|---|---|
| The builder picks up at the store (local rate 4.5%) | 9.5% | $1,900 | The store’s parish |
| The company delivers to a job site in another parish (local rate 5.5%) | 10.5% | $2,100 | The job site’s parish |
If the company charges its store rate on the delivery, it comes up $200 short. In an audit, the job site’s parish can bill the company for that $200, plus penalties and interest. Multiply that across a year of deliveries, and it adds up fast.
It works the other way too
The same rules apply when you’re the buyer. If you buy equipment in a parish with a lower rate, or from an out-of-state vendor that doesn’t charge Louisiana local tax, and then use it in your own parish, you may owe local use tax on the difference. Parishes do give credit for local sales tax you already paid to another Louisiana parish.
Out-of-state and online sellers
A business with no physical presence in Louisiana has to start collecting once its gross sales delivered into the state top $100,000 in the current or previous calendar year. Louisiana dropped its old 200-transaction test on August 1, 2023. These remote sellers register with the Louisiana Sales and Use Tax Commission for Remote Sellers and collect state tax plus the actual local rate at the customer’s address. The old flat-rate option for remote sellers ended in 2020. Marketplace facilitators with more than $100,000 in Louisiana retail sales have the same obligation.
Where businesses get it wrong
The most common mistake is charging your home rate on every sale. It’s an easy habit for a business that started with one location. If you deliver, set up your invoicing or point-of-sale system to calculate tax from the delivery address.
The next one is charging the right rate but sending the money to the wrong place. The local tax has to go to the parish where the sale is sourced. Keep a list of every parish you deliver into and make sure you have an account with each collector.
ZIP codes cause a lot of errors too. A single ZIP code can cross city limits and district lines, so look up rates by full street address. The Remote Sellers Commission has an address-based rate lookup you can use.
A lot of businesses also missed the 2025 changes. Software subscriptions and other digital products are taxable now. That affects you whether you sell them or buy them from a vendor that doesn’t charge Louisiana tax. Keep in mind that some state and local exemptions don’t match, so an item that’s exempt from state tax isn’t always exempt locally.
Use tax on your own purchases is easy to forget until an auditor asks about it. Equipment and supplies bought out of state, or in a lower-rate parish, can create a local use tax bill.
Filing got a little easier this year. Since February 2026, you can file your state and local sales tax returns together through Parish E-File, starting with January 2026 sales. It’s one return, but payments still go separately to LDR and to each local taxing authority, and other filing methods are still available. One rule did tighten: since January 1, 2026, all state sales tax returns and payments must be filed electronically, no matter how small.
A simple monthly routine prevents most of these problems:
- Record the delivery address on every invoice.
- Calculate tax from that address using a current rate lookup.
- Register with the collector in each parish you deliver to regularly.
- Review your purchases for anything that owes use tax.
- Reconcile the tax you collected against the tax you filed for each parish.
Frequently asked questions
What is the sales tax rate in Louisiana?
The state rate is 5%. Local rates are added on top and run as high as 7%. The average combined rate was 10.13% as of July 1, 2026.
If I deliver to a customer in another parish, which rate do I charge?
