The Plaquemines Parish sales tax rate is 9.75 percent on most retail purchases, made up of 5 percent to the state of Louisiana and 4.75 percent to local taxing bodies. Food for home consumption, prescription drugs, and commercial fishing supplies are taxed at a reduced combined rate of 8.50 percent. The Plaquemines Parish Government Sales Tax Division in Belle Chasse is the single local collector for registration, filing, and enforcement.
The Rate, Line by Line
Louisiana’s statewide rate rose to 5 percent on January 1, 2025 after the 2024 Third Extraordinary Legislative Session replaced the prior 4.45 percent rate and restructured several exemptions.1Louisiana Department of Revenue. General Sales and Use Tax If your point-of-sale system hasn’t been updated since 2024, it is almost certainly charging the wrong amount.
The 4.75 percent local share funds four separate entities:2Louisiana Association of Tax Administrators. Plaquemines Parish
- School Board: 2.50 percent on general merchandise, 1.50 percent on food, drugs, and commercial fishing supplies
- Parish Government: 1.00 percent
- Fire Department: 1.00 percent
- Law Enforcement District (Sheriff’s Department): 0.25 percent, added July 1, 2025
On a typical retail sale, those four pieces plus the 5 percent state rate come to 9.75 percent. On food for home consumption, prescription drugs, and commercial fishing supplies, the School Board’s share drops by a full point and the combined rate falls to 8.50 percent.2Louisiana Association of Tax Administrators.

Hotels and short-term rentals carry an additional 2 percent occupancy tax on room charges, collected alongside but separately from general sales tax.2Louisiana Association of Tax Administrators. Plaquemines Parish
What Gets Taxed
Sales tax applies to tangible personal property, which Louisiana defines as anything you can see, weigh, measure, or touch. That covers clothing, electronics, furniture, building materials, vehicles, and similar goods. Prepaid calling cards and prepaid wireless services are also classified as tangible personal property under the statute and taxed at the same rate.3Louisiana State Legislature. Louisiana Revised Statutes 47:301 – Definitions
Several services are taxable too: repairs and maintenance on tangible personal property, telecommunications, cable and satellite, hotel and short-term lodging, admissions to entertainment venues, and the leasing or renting of tangible personal property. The Louisiana Department of Revenue publishes service-specific guidance for borderline cases.
Use Tax
Use tax is the backstop. If you buy something outside the parish or online from a seller that didn’t collect Louisiana tax, and you bring it into Plaquemines Parish for your own use, you owe use tax at the same rate as sales tax. Businesses that order equipment, supplies, or inventory from out-of-state vendors without paying tax at purchase commonly owe use tax and should report it with their regular filings.
Common Exemptions
Not every transaction triggers tax. The exemptions you’ll see most often in Plaquemines Parish:
- Sales for resale, if the buyer presents a valid resale certificate that includes the parish of their principal place of business and their local sales tax account number.3Louisiana State Legislature. Louisiana Revised Statutes 47:301 – Definitions
- Direct sales to the U.S. government, the State of Louisiana, or any political subdivision.
- Isolated or occasional sales by someone not regularly in the business of selling.
- Food for home consumption, prescription drugs, and commercial fishing supplies, which are not fully exempt but taxed at the reduced 8.50 percent rate.2Louisiana Association of Tax Administrators. Plaquemines Parish
Keep documentation for every exempt sale. When an auditor questions a transaction, the burden is on you to prove the exemption applied. A missing resale certificate on a $50,000 wholesale invoice means you owe the full tax.
One trap from the 2024 reform: many state-level exemptions enacted between July 1, 2003 and January 1, 2025 no longer apply to local sales taxes unless the statute specifically said they did.4Louisiana State Legislature. Act No. 11, 2024 Third Extraordinary Session If your business has relied on a particular exemption, confirm it still covers the local portion.
Registering Before Your First Sale
Before your first taxable sale in Plaquemines Parish, register with the Sales Tax Division of the Plaquemines Parish Government in Belle Chasse. You can download the Sales and Use Tax Application from the parish website or contact the office directly.5Plaquemines Parish, LA. Sales Tax Division
The application asks for your FEIN or Social Security Number, your legal business name as registered with the Louisiana Secretary of State, your physical and mailing addresses, your NAICS code, the date you started or will start making taxable sales, and an estimate of your expected monthly tax liability. That estimate drives your filing frequency: most businesses file monthly, and lower-volume sellers may qualify for quarterly. Make sure your legal name matches your federal records exactly, because mismatches push registration back by weeks.
The Occupational License Is Separate
Sales tax registration is not the only step. You also need an occupational license, which is handled by the Plaquemines Parish Sheriff’s Office Tax Division through the MuniLicense online portal.6Plaquemines Parish Sheriff’s Office. Tax Office Two different offices, two different requirements, and both must be in place before you open.
One-Time Event Vendors
If you’re selling at a festival or event on public property, submit a Special Event Application to the Plaquemines Parish Government Buildings Department at least 30 days before the event. The single-event permit fee is $20, you’ll need to provide your Tax ID, and alcohol sales require separate parish and state liquor licenses. Event organizers must also carry at least $1 million in commercial general liability insurance naming the Plaquemines Parish Government as an additional insured.7Plaquemines Parish Government. Special Event Application for Public Property
Filing and Paying
Returns are due on the 20th of the month following the reporting period.1Louisiana Department of Revenue. General Sales and Use Tax Tax collected in January is reported and paid by February 20. When the 20th falls on a weekend or holiday, the deadline usually moves to the next business day.
The simplest filing route is Parish E-File, a free tool from the Louisiana Department of Revenue that handles both state and local returns from one site.8Louisiana Department of Revenue. Parish E-File The Department’s Sales Tax Filing Options page lists additional electronic methods.9Louisiana Department of Revenue. Sales Tax Filing Options Paper returns can be mailed to the Plaquemines Parish Sales Tax Division.
File for every reporting period, even one with zero taxable sales. Skipping a quiet month puts your account in delinquent status and starts the penalty clock on a return you didn’t technically owe anything on.
Late Filing and Payment Penalties
If you file late or don’t file at all, the penalty is 5 percent of the tax due for the first 30 days of delinquency and another 5 percent for each additional 30-day period, capped at 25 percent of the tax owed.10Louisiana State Legislature. Louisiana Revised Statutes 47:1602 – Specific Penalties
Filing on time but paying short has its own penalty: 5 percent of the unpaid balance for each 30-day period the shortfall continues, also capped at 25 percent.10Louisiana State Legislature. Louisiana Revised Statutes 47:1602 – Specific Penalties
Interest runs on top of penalties. The annual rate is three percentage points above Louisiana’s judicial interest rate, with a ceiling of 1.25 percent per month.11Louisiana State Legislature. Louisiana Revised Statutes 47:1601 – Interest on Unpaid Taxes At the maximum rate, a $10,000 unpaid balance generates $125 per month in interest alone, and that balance compounds. The math gets ugly fast on larger numbers.
Remote Sellers and Marketplace Platforms
Out-of-state sellers aren’t exempt from Plaquemines Parish tax. If your gross revenue from Louisiana retail sales exceeds $100,000 in the current or preceding calendar year, you must collect and remit both state and local tax on deliveries into Louisiana.12Louisiana State Legislature. Louisiana Revised Statutes – Marketplace Facilitators Collection and Remittance of State and Local Sales and Use Tax Register with the Louisiana Sales and Use Tax Commission for Remote Sellers within 30 days of crossing the threshold and start collecting within 60 days.
Marketplace facilitators such as Amazon, eBay, and Etsy carry the same duty. Once a facilitator’s total Louisiana sales cross $100,000, the platform becomes the dealer responsible for collecting and remitting tax on every Louisiana transaction made through it, including third-party sales.12Louisiana State Legislature. Louisiana Revised Statutes – Marketplace Facilitators Collection and Remittance of State and Local Sales and Use Tax Individual sellers on a marketplace generally don’t count those platform-facilitated sales toward their own $100,000 threshold.
If you sell only through a major marketplace, the platform probably handles your Plaquemines Parish obligations. If you also sell through your own website or at local events, track those direct sales separately. You may need your own registration.
Records and Disputing an Assessment
Louisiana law requires you to keep sales tax records for at least five years from December 31 of the year the tax became due.13Louisiana State Legislature. Louisiana Revised Statutes 44:36 – Preservation of Records That means invoices, receipts, exemption and resale certificates, and copies of filed returns. Digital works, provided you can produce it quickly on request.
If you receive an assessment you believe is wrong, Plaquemines Parish uses a payment-under-protest procedure. You pay the assessed amount and then file suit to recover it. It is litigation, not a casual appeal, but it is the recognized mechanism for disputing a local assessment.
Voluntary Disclosure if You’re Behind
If you’ve been operating in the parish without a sales tax registration and the Department of Revenue hasn’t contacted you yet, you may qualify for a voluntary disclosure agreement. You pay back taxes and interest for the current calendar year plus the three preceding years, and the state waives delinquency penalties.14Louisiana Department of Revenue. Voluntary Disclosure Agreement
There is one significant catch. If you collected tax from customers but never remitted it, the look-back period extends to every period you held unremitted tax, and penalties will not be waived.14Louisiana Department of Revenue. Voluntary Disclosure Agreement You can apply anonymously first to understand your exposure before disclosing your identity. Once the Department contacts you about a potential liability, the voluntary disclosure door closes.
