Ouachita Parish Sales Tax: Rates, Exemptions, and Filing

The Ouachita Parish sales tax runs from 10.50% to 13.50% depending on where in the parish the sale takes place. That total combines Louisiana’s 5% state rate with local taxes collected by the parish school board, police jury, sheriff’s office, fire protection districts, and any applicable city or economic development district. The lowest combined rate is in Richwood; the highest is inside the Sterlington Economic Development District.

Combined Rates by City and Area

Louisiana’s state sales tax rose to a flat 5% on January 1, 2025, replacing the previous 4.45% rate. The new rate is scheduled to stay in place through December 31, 2029.¹ On top of that, Ouachita Parish adds between 5.50% and 8.50% in local tax.

The combined rates in effect as of January 1, 2025 are:²

Monroe: 10.99% (5.99% local + 5% state)
West Monroe: 10.99% (5.99% local + 5% state)
Sterlington: 11.50% (6.50% local + 5% state)
Richwood: 10.50% (5.50% local + 5% state)
East Ouachita, unincorporated: 10.99% (5.99% local + 5% state)
West Ouachita, unincorporated: 10.99% (5.99% local + 5% state)

The unincorporated parts of the parish carry the same 10.99% total as Monroe and West Monroe. The local components are divided differently among the parish’s taxing bodies, but the amount at the register is identical. Richwood is the lowest in the parish at 10.50%, and Sterlington’s base municipal rate of 11.50% is the highest outside of the development districts.

Economic Development District Surcharges

Several areas sit inside Economic Development Districts that add extra sales tax to fund infrastructure within those zones. If you’re shopping in one, your receipt will show a higher rate than the surrounding city:²

West Monroe EDD: 11.99%
West Monroe Riverfront EDD: 11.99%
Walnut Street EDD: 12.99%
Sterlington EDD: 13.50%

The Sterlington EDD is the highest combined rate anywhere in the parish. The extra 2% above the standard Sterlington rate goes to debt service and capital improvements inside the district. Receipts generally won’t itemize the EDD portion, so a shopper may pay a noticeably higher rate without realizing the store sits inside one of these zones.

What’s Taxed Less or Not at All

Groceries and Prescription Drugs

Louisiana exempts groceries and prescription drugs from the 5% state sales tax. Food bought for home preparation, including bakery items, dairy, fresh produce, and packaged foods that require further preparation, is state-exempt,³ and prescription drugs get the same treatment.⁴

Local taxes are a different story. The Louisiana Constitution allows parishes and cities to keep taxing groceries and prescriptions even when the state portion is waived.⁵ In Monroe, the local rate on food and drugs is 4.99%, so the combined rate for those items is 9.99% instead of the full 10.99%.² Groceries in Louisiana are cheaper at checkout than other goods, but they are not tax-free.

Manufacturing Machinery and Equipment

Machinery and equipment used directly in manufacturing are exempt from the state sales tax when used at a fixed plant location to produce goods for sale.⁶ Consumables like lubricants and conveyor belts can also qualify for certain eligible manufacturers.

Local jurisdictions may adopt the same exemption by ordinance but are not required to.⁶ In the areas of Ouachita Parish that have adopted it, the local rate on qualifying equipment drops to 3.99%, bringing the combined rate to 8.99%.² Before claiming the lower rate, confirm with the parish tax commission that your location and specific equipment qualify.

Business Utilities

A reduced state rate of 2% applies to utilities such as electricity and natural gas used in commercial operations.¹ For warehouse and manufacturing operations in the parish, this can meaningfully affect monthly utility bills.

Casual and Occasional Sales

If you sell personal belongings and you aren’t in the business of selling, the sale is exempt from all Louisiana sales tax, both state and local. The exemption covers isolated or occasional sales of property by someone who isn’t engaged in that line of business.³ Selling used furniture through a local marketplace page qualifies. Regularly reselling goods for profit does not.

Online and Out-of-State Purchases

When you buy from an online or out-of-state seller that doesn’t collect Louisiana tax, you still owe tax on the purchase. It’s called consumer use tax, and it exists so that shopping across state lines doesn’t become a way around the local rate.⁷

For individuals buying for personal use, Louisiana charges a flat combined use tax of 9% on taxable items purchased on or after January 1, 2025. That 9% applies regardless of the actual combined rate where you live in Ouachita Parish.⁸ You report it on your Louisiana individual income tax return or on a separate Form R-1035. The deadline matches your income tax due date; for 2025 purchases, that’s May 15, 2026.

Businesses can’t use the consumer use tax return. They report use tax through their regular dealer sales tax filings with the state and local authorities.⁸ Many large online retailers already collect Louisiana tax at checkout, in which case there’s nothing more to report on that purchase.

Registering, Filing, and Paying as a Business

If your business is in Monroe, register for a local sales tax number through the City of Monroe’s Tax and Revenue Division and obtain an occupational license before opening.⁹ Businesses in other municipalities or in the unincorporated parish register with the Ouachita Parish Sales and Use Tax Commission. State sales tax registration is handled separately through the Parish E-File portal.¹⁰ Have your legal business name, FEIN or Social Security number, start date, physical address, and owner information ready.

Most businesses file monthly. A return is delinquent after the 20th of the month following the reporting period, and if the 20th falls on a weekend or holiday, the postmark deadline moves to the next business day.⁹ A late return triggers a 5% penalty of the total tax due for a delinquency of 30 days or less, with additional penalties as the delay grows. Interest also runs on the unpaid balance from the original due date. If cash is tight, file on time anyway. Failure-to-file penalties stack on top of failure-to-pay charges, so filing the return beats skipping it.

Returns can be submitted and paid electronically through the parish tax commission’s online system, or by mailing paper returns and checks. The Louisiana Uniform Local Sales Tax Board keeps current contact information and portal links for Ouachita Parish.¹¹
