The Lincoln Parish sales tax ranges from 8.75% to 11%, combining Louisiana’s 5% state rate with a local rate that depends on whether the sale happens in Ruston, Grambling, Choudrant, or the unincorporated parish. Any business selling taxable goods in the parish needs to register with both the Louisiana Department of Revenue and the Lincoln Parish Sales and Use Tax Commission, then file returns by the 20th of each month.
Rates by Location
Every taxable sale carries two layers of tax: the 5% Louisiana state rate (effective January 1, 2025) and a local rate that varies by jurisdiction.1Louisiana Department of Revenue. What Is the State Sales Tax Rate? The local portion funds the parish school board, police jury, sheriff’s department, and, where applicable, the city.
- Unincorporated Lincoln Parish: 3.75% local + 5% state = 8.75%
- Ruston: 6% local + 5% state = 11%
- Grambling: 6% local + 5% state = 11%
- Choudrant: 4.75% local + 5% state = 9.75%
Ruston and Grambling each add a 2.50% city tax on top of the baseline parish taxes, and Choudrant adds 1.25%.2Louisiana Association of Tax Administrators. Lincoln Parish Outside any municipality, no city levy applies, so the local rate stays at 3.75%.
What’s Exempt
Louisiana exempts several categories of goods from the state portion of the tax:
- Food purchased for home consumption. Prepared food and restaurant meals remain taxable.
- Prescription drugs prescribed by a physician or dentist.
- Residential electricity, natural gas, and water.
- Trade-ins: when a customer trades in an article toward the purchase of a new one, the trade-in value reduces the taxable amount.
These apply to the state tax.3Louisiana Department of Revenue. Are There Any Exemptions From the Sales Tax? Local parishes and municipalities may or may not mirror every state exemption, so sellers should confirm with the Lincoln Parish Sales and Use Tax Commission whether a particular item is also exempt from the local levy.
Which Rate Applies to a Sale
Louisiana uses destination-based sourcing. The tax rate is set by where the buyer receives the goods, not where the seller operates. A Ruston business shipping an order to an address in unincorporated Lincoln Parish charges 8.75% because that’s where the buyer takes possession.4Louisiana Department of Revenue. How Are Sales Sourced? When a customer picks goods up at the store, the sale is sourced to the business address.
Getting sourcing wrong is one of the easiest ways to underpay one jurisdiction while overpaying another, which creates problems during an audit even if the total tax collected was correct.
Registering to Collect
Before collecting a dollar of sales tax, a business needs two registrations.
State Registration
Complete Form R-16019, the Application for Louisiana Revenue Account Number.5Louisiana Department of Revenue. Application for Louisiana Revenue Account Number You can file it online through the Louisiana Taxpayer Access Point (LaTAP), the state’s portal for registrations, returns, and payments.6Louisiana Department of Revenue. Louisiana Department of Revenue The application asks for your Federal Employer Identification Number, legal business name as registered with the Louisiana Secretary of State, physical address, a description of your business activity, and identification for all principal owners. There is no fee.
Local Registration
The Lincoln Parish Sales and Use Tax Commission handles the local side separately. Submit your application to P.O. Box 863, Ruston, LA 71273, or call 318-251-8624 with questions.7Louisiana Uniform Local Sales Tax Board. Lincoln Parish Sales and Use Tax Commission The local form asks for similar information to the state form, plus your NAICS code and expected monthly sales volume. Processing for both registrations typically takes one to two weeks. Once approved, you receive a physical sales tax certificate, which must be displayed at your place of business and also lets you make tax-exempt purchases from wholesalers.
Filing and Paying
Most Lincoln Parish businesses file monthly. Returns are due by the 20th of the month after the reporting period, so January sales are reported and paid by February 20.8Louisiana Department of Revenue. Sales and Use Tax
State and local returns go through different systems. Local taxes are filed on Parish E-File, which lets you report returns for multiple jurisdictions within the parish from one site.9Parish E-File. Parish E-File State taxes are filed through LaTAP. Both platforms accept bank drafts and credit card payments. On each return you report gross sales, subtract exempt sales, and calculate tax on the taxable amount. Because the parish has multiple rates, Parish E-File breaks the calculation out by location so funds get distributed correctly.
Vendor’s Compensation
Louisiana rewards on-time filers with a small deduction called vendor’s compensation. Dealers may deduct 1.05% of the state tax due before remitting, though it only applies to certain components of the state levy. With the current rate structure, the effective deduction works out to about 0.84% of the total state sales tax collected.10Louisiana Department of Revenue. What Is the State’s Vendor’s Compensation Deduction Rate? It isn’t a large amount, but it adds up over a year, and you forfeit it entirely if you file late.
Late Penalties and Interest
Missing the 20th triggers an immediate penalty of 5% of the tax owed. Another 5% is added for each additional 30 days the return remains delinquent, capped at 25%.11Louisiana State Legislature. Louisiana Code RS 47:1602 – Penalty for Failure to Make Timely Return A $2,000 balance filed three months late carries a $300 penalty on top of the tax.
Interest accrues separately. The rate is reset annually and capped at 1.25% per month.12Louisiana State Legislature. Louisiana Code RS 47:1601 – Interest For 2025, the annual rate is 11.25%, and it compounds daily.13Louisiana Department of Revenue. Interest Rate Schedule Between penalty and interest, a tax balance can grow by a third or more within a few months of going delinquent.
Remote Sellers
Businesses outside Louisiana may still have to collect Lincoln Parish tax. Louisiana’s economic nexus threshold requires registration if a remote seller has more than $100,000 in gross Louisiana revenue, or completes 200 or more separate transactions delivered into the state during the previous or current calendar year.14Louisiana Remote Sellers Commission. Frequently Asked Questions Remote sellers register through the Louisiana Remote Sellers Commission rather than LaTAP. Because sourcing is destination-based, they charge the rate at the buyer’s delivery address: 11% to a Ruston address, 8.75% to an address outside any city limits.2Louisiana Association of Tax Administrators. Lincoln Parish
Buying an Existing Business
If you buy a Lincoln Parish business, you can inherit the seller’s unpaid sales tax. Louisiana law requires the buyer to withhold enough of the purchase price to cover any outstanding taxes, interest, and penalties until the seller produces a clearance letter from the Louisiana Department of Revenue confirming the account is clear.15Louisiana Department of Revenue. Successor Liability
The Department of Revenue will not honor any contract between buyer and seller that tries to shift this responsibility. Close without the clearance letter and you can be on the hook up to the full amount you paid for the business. Requesting the letter costs nothing.
How Long to Keep Records
Louisiana allows the Department of Revenue to review records going back at least five years from the end of the year in which the tax became due.16Louisiana State Legislature. Louisiana Code RS 44:36 Treat five years as the minimum. If you’re in a pending audit, dispute, or refund claim, keep the related records until it’s fully resolved.
Keep sales invoices, exemption certificates from customers, purchase receipts, filed returns, and payment confirmations. Parish E-File and LaTAP both store filing history, but don’t rely only on those portals. Download and save local copies. When an auditor arrives, the burden is on you to show that the tax you collected and remitted matches your records.
