Terrebonne Parish sales tax is a 5.5% local levy that combines with Louisiana’s 5% state rate for a total of 10.5% on most retail sales, leases, and taxable services delivered within the parish.1Terrebonne Parish Consolidated Government. Sales and Use Tax Rates2Louisiana Department of Revenue. What Is the State Sales Tax Rate? The Terrebonne Parish Sales and Use Tax Department collects the local portion, and any business selling goods, renting property, or providing taxable services in the parish must register with the department before collecting a dime.
The Current Rate
The 5.5% local rate has been in place since April 1, 2015, and it consolidates every parish taxing authority, including the school board and the consolidated government, into a single levy.1Terrebonne Parish Consolidated Government. Sales and Use Tax Rates The state’s 5% share took effect January 1, 2025 and is set to hold through the end of 2029.2Louisiana Department of Revenue. What Is the State Sales Tax Rate?
The 10.5% rate is uniform across the parish. There’s no lower rate for unincorporated areas. A sale in downtown Houma and a sale in Chauvin carry the same combined rate.3Louisiana Association of Tax Administrators. Terrebonne Parish
One notable exception: business utilities are taxed at a reduced state rate of 2% instead of 5%, so the combined rate on commercial electricity and natural gas is lower than 10.5%.2Louisiana Department of Revenue. What Is the State Sales Tax Rate?
Who Has to Collect It
Louisiana’s definition of “dealer” is broad. If you sell tangible goods, lease equipment, or provide taxable services in Terrebonne Parish, you likely qualify. The statute reaches anyone maintaining an office, warehouse, or business location in the parish, sending sales representatives into the area, keeping inventory locally, or making deliveries in their own vehicles.4Louisiana State Legislature. Louisiana Code 47:301 – Definitions Temporary vendors at festivals and trade shows have to register too.
You apply for a sales tax certificate from the Terrebonne Parish Sales and Use Tax Department before you begin collecting. Operating without one puts you inside a penalty structure that adds up fast.
Remote Sellers and Marketplace Platforms
Out-of-state businesses trigger Louisiana collection obligations once they cross either threshold during the previous or current calendar year: $100,000 in gross Louisiana revenue, or 200 or more separate transactions delivered into the state.5Louisiana Department of Revenue. Remote Sellers FAQs
Remote sellers don’t register with each parish separately. Louisiana routes everything through the Louisiana Sales and Use Tax Commission for Remote Sellers, which handles registration, filing, and remittance for out-of-state businesses and distributes the collected tax to Terrebonne Parish and other local collectors.6Louisiana Sales and Use Tax Commission for Remote Sellers. Louisiana Sales and Use Tax Commission for Remote Sellers
If you sell through a marketplace like Amazon, Etsy, or Walmart, the platform collects and remits the tax on marketplace transactions. Louisiana law makes the marketplace facilitator the dealer for those sales.7Louisiana Sales and Use Tax Commission for Remote Sellers. RSIB 23-001 Marketplace Facilitators and Louisiana Merchants Sales you make off-platform, through your own website or a physical location, remain your responsibility.
What’s Taxable
The tax covers retail sales of tangible personal property, leases and rentals, and certain services. Furniture, electronics, clothing, building materials, auto parts: if you can hold it and you’re buying it at retail, it’s almost certainly taxed. Leasing equipment or renting a vehicle carries the same rate.8Justia Law. Louisiana Revised Statutes 47:302 – Imposition of Tax
As of January 1, 2025, Louisiana expanded the base to include digital products. Downloads, streaming content, and similar digital goods are now taxable at both state and local levels.9Louisiana Department of Revenue. Are Digital Products Subject to Sales and Use Tax? If you sell software downloads, e-books, or digital subscriptions to Terrebonne Parish customers, you collect the full 10.5%.
Taxable services in Louisiana include repair of tangible property, hotel and short-term rentals, and telecommunications. Purely professional services like legal advice or accounting generally are not taxed.
Common Exemptions
A few categories fall outside the tax:
- Resale purchases, when you provide a valid resale certificate to your supplier. Without the certificate, the seller has to charge you tax.
- Prescription drugs and insulin, exempt from both state and local sales tax whether the insulin requires a prescription or not.
- Manufacturing machinery and equipment used directly in the manufacturing process, though the specifics and application process can be involved.
Documentation matters more than most owners realize. If you claim an exemption and can’t produce the paperwork in an audit, the parish will assess the tax as if the exemption never existed, plus penalties and interest running from the original due date.
Registering With the Parish
New businesses submit an Application for Registration Certificates to the Terrebonne Parish Sales and Use Tax Department. The form asks for the legal and trade names, your Federal Identification Number (or SSN for sole proprietors), physical and mailing addresses, a description of your business activities, and identifying information for all owners, corporate officers, LLC members, or partners, along with a copy of each person’s driver’s license.10Terrebonne Parish Sales and Use Tax Department. Application for Registration Certificates and/or Occupational License You can submit it by mail, email, fax, or in person. Wait for your certificate before you begin collecting.
Buying an Existing Business
If you’re purchasing an existing business, pay close attention to its sales tax history. Under successor liability rules, a buyer can inherit the seller’s unpaid sales tax debts even if the purchase agreement says otherwise. Request a tax clearance certificate from the Terrebonne Parish Sales and Use Tax Department before closing. If the seller owes back taxes and you close without verifying, the parish can pursue you for the balance.
Filing Returns and Making Payments
Sales tax returns are due on the first day of the month following the reporting period, and they become delinquent on the 21st. You have a 20-day window to file and pay without penalty.11Terrebonne Parish Consolidated Government. Filing Returns January’s tax, for example, must be filed and paid by February 20.
The parish prefers Parish E-File, a free online portal that handles both state and local returns. You’ll need your sales tax account number, an email address, and bank routing and account numbers to register.11Terrebonne Parish Consolidated Government. Filing Returns Paper returns are accepted by mail, email, fax, or in-person drop-off, and checks are made payable to the Terrebonne Parish Sales and Use Tax Department. Electronic payment removes any question about whether your payment arrived on time.
Vendor Compensation
Louisiana rewards timely filers with a small deduction. You can keep a portion of the state sales tax you collect as compensation for the work of collecting and remitting it, currently at an effective rate of 0.84% of state taxes due.12Louisiana Department of Revenue. What Is the State Vendor Compensation Deduction Rate? The deduction applies only to the state portion, not the 5.5% parish share.
Penalties and Interest for Late Filing
Missing the 20th triggers two charges that run at the same time. The penalty is 5% of the unpaid tax for each 30-day period (or any part of one) the return is delinquent, with a $10 minimum regardless of how small the balance. Interest runs at 1% per month from the original due date until the tax is paid.13Louisiana Association of Tax Administrators. Parish of Terrebonne Sales Tax Return
Those charges compound. A business owing $5,000 that files three months late faces $750 in penalties (5% × 3 periods) plus $150 in interest (1% × 3 months), for $900 in added cost on top of the tax itself. Persistent non-compliance can lead to revocation of your sales tax certificate or legal collection action.
Audits and Appeals
The parish can audit your records within the applicable look-back period. If the auditor finds a discrepancy, you’ll first receive a Notice of Intent to Assess, sometimes called the “30-day letter.” You have 30 days to respond in writing with documentation. This is the best window to resolve a dispute informally.
If it isn’t resolved, the parish issues a formal Notice of Assessment. You then have 60 days to pay the assessment, file a protest with the Louisiana Board of Tax Appeals, or pay under protest and petition the Board for a refund. Missing the 60-day window locks in the assessment and ends your appeal rights. At the Board of Tax Appeals you can represent yourself, hire an attorney, or have a CPA argue on your behalf.
How Long to Keep Records
Louisiana requires businesses to retain tax records for seven years.14Louisiana Legislative Auditor. Public Records Retention FAQ That includes sales receipts, exemption certificates, purchase invoices, and copies of every return you’ve filed. Organized, accessible records are the single most effective way to survive an audit without owing more. If you can’t prove a claimed exemption or a reported figure, the auditor will assess the tax as though the exemption never applied.
