Mississippi does not issue a resale certificate form. To buy inventory tax-free for resale in Mississippi, you register for a state sales tax permit through the Department of Revenue and then give each supplier the permit number printed on it, formatted as two sets of four digits (for example, 1234-5678). Many suppliers will ask you to sign a one-page blanket certificate of resale that carries that number, but the number itself is the exemption. The standard sales tax rate is 7%, so getting this right on inventory purchases matters.
Register for a Mississippi Sales Tax Permit First
You need an active permit before you make any tax-free resale purchases. Mississippi law requires anyone engaging in a business activity subject to sales tax to apply for a permit before the first sale or purchase for resale. A business that starts operating without one owes the full 7% retail rate on every purchase during the unregistered period, including items that would have qualified as wholesale.1Mississippi Legislature. Mississippi Code 27-65-3 – Definitions
Register through the Mississippi Taxpayer Access Point (TAP) at tap.dor.ms.gov. There is no government fee. Have these on hand before you start:
- Business name and mailing address
- Social Security Number or ITIN, for sole proprietors
- Federal Employer Identification Number (FEIN) and Secretary of State Business ID, for corporations, partnerships, and LLCs
Businesses that operate in Mississippi without a permanent physical location in the state must post a sales tax bond or an approved surety cash bond as part of the application.2Mississippi Department of Revenue. Register for Taxes You need a separate permit for each business location. The permit does not expire and does not require renewal as long as the business keeps operating in the same capacity at the same location.3Mississippi Department of Revenue.

What the Resale Exemption Actually Covers
Mississippi’s wholesale sale definition has two requirements that must both be met: the buyer must be a licensed dealer under Mississippi Code § 27-65-27, and the purchase must be for resale in the buyer’s regular line of business.4Cornell Law Institute. 35 Mississippi Code R 4-03-01-101 – Wholesale Sales A clothing boutique buying shirts to stock the sales floor qualifies. That same boutique buying a desk for its back office does not. The desk is for internal use, and internal-use purchases stay taxable.
The exemption also covers services purchased for resale, packaging materials that will pass to the customer with the product, and component materials bought by contractors holding a Material Purchase Certificate for a qualifying job.4Cornell Law Institute. 35 Mississippi Code R 4-03-01-101 – Wholesale Sales
One boundary catches out-of-state buyers. Mississippi is not a member of the Streamlined Sales Tax Agreement, so the multistate SST exemption certificate is not accepted here.5Streamlined Sales Tax Governing Board. Mississippi If you regularly buy for resale in Mississippi from outside the state, you generally need to register for a Mississippi permit through TAP to claim the exemption.
How to Give a Supplier Your Resale Information
The practical step is simple: give the seller your Mississippi sales tax permit number at the time of purchase. Many suppliers will ask you to sign a blanket certificate of resale, a one-page document stating that qualifying purchases from that vendor are for resale. A blanket certificate saves both parties from repeating paperwork on every order.
A blanket certificate typically includes:
- Buyer’s legal business name and address
- Seller’s legal business name
- Mississippi sales tax permit number
- Description of the goods purchased for resale, which can be a general category like “women’s apparel” or “auto parts”
- Signature and date from an authorized representative of the buying business
The goods description matters. It should match what the business actually sells. A restaurant supplier claiming resale on industrial cleaning equipment will raise questions during an audit. Keep the category accurate even if broad, because auditors compare what you claimed to buy for resale against the nature of your reported sales.
Expect suppliers to verify your permit before honoring the exemption. The DOR offers a permit verification tool at tap.dor.ms.gov where a seller can enter your number and confirm it is active.6Mississippi Department of Revenue. Verify a Sales Tax Number If your permit shows inactive, or if the products don’t line up with your registered business type, the supplier is expected to collect the 7% tax.7Mississippi Department of Revenue.

Drop Shipping Situations
Drop shipping brings a third party into the picture. When a supplier ships directly to a Mississippi location on behalf of a retailer, the supplier must charge Mississippi sales tax unless the retailer provides a valid exemption document. If the retailer has a Mississippi sales tax permit, a copy of that permit or a certificate goes to the supplier.
If the retailer is out-of-state and has no Mississippi permit, the DOR allows a flow-through process where the Mississippi end customer’s exemption passes through the retailer to the supplier. The supplier needs one of the following from the end customer:8Mississippi Department of Revenue. Drop Shipments
- A copy of the customer’s Mississippi sales or use tax permit, if the product is intended for resale
- A copy of the customer’s direct pay permit
- A copy of the customer’s Material Purchase Certificate, for contractors on a qualifying job
- Verification of the customer’s exemption status under Mississippi Code §§ 27-65-101 through 27-65-111
Records You Need to Keep
Mississippi Code § 27-65-43 requires every taxable business to keep adequate records for at least three years. That includes invoices of merchandise purchased, bank statements, canceled checks, and any other documentation needed to determine tax liability. Records must be stored at the taxpayer’s principal place of business within Mississippi and made available to the DOR at any time.9Justia. Mississippi Code 27-65-43 – Taxpayer Must Keep Records
For resale purchases specifically, hold on to:
- Copies of blanket certificates you signed with suppliers
- Purchase invoices showing tax was not charged
- Records of what was bought and when, so it can be matched to downstream taxable sales
The three-year window can stretch. If the DOR opens an examination within the 36-month assessment period, it can extend by one additional year. A written agreement with the DOR can extend it further, and if a business fails to file returns or files a fraudulent one, there is no statute of limitations at all. Keeping records for four years is the safer practice.
What Happens If You Misuse the Exemption
Using your permit number to buy items for personal use or internal business use is tax evasion. Failure to keep the required records, or to allow the DOR to examine them, triggers the penalties in Mississippi Code § 27-65-85 on top of the unpaid tax plus interest.9Justia. Mississippi Code 27-65-43 – Taxpayer Must Keep Records
Operating without a permit is worse. Under § 27-65-3, an unregistered business owes the full 7% retail rate on every purchase made during the unregistered period, even items that would have qualified for the resale exemption if the business had been properly permitted. After registering, the business can claim a credit for tax overpaid on qualifying wholesale purchases, but penalties and interest for the unregistered period still apply.1Mississippi Legislature. Mississippi Code 27-65-3 – Definitions
Organized digital copies of your permit, blanket certificates, and purchase invoices are the simplest way to come through an audit cleanly. The records don’t need to be elaborate. They need to be complete and retrievable.
