Resellers are tax exempt on the inventory they buy for resale, and only on that inventory. The resale exemption lets a registered business skip sales tax when purchasing goods it intends to sell to customers, but it doesn’t turn the business into a tax-free entity. Anything the business buys for its own use — office supplies, equipment, furniture, tools — remains fully taxable. To claim the exemption, you need to be registered with the state and hand your supplier a completed resale certificate at the time of purchase.
What the Resale Exemption Actually Covers
The exemption applies to tangible personal property bought with genuine intent to resell in the ordinary course of business. That covers finished goods heading straight to customers, raw materials that become part of a manufactured product, and component parts incorporated into something the business sells. The test is whether the item will pass through to a customer or be consumed by the business itself.
Items used internally never qualify, even when the business sells similar items to the public. A clothing retailer pays tax on the mannequins and hangers. A restaurant supply company pays tax on the blender it puts in its own breakroom. This is the line that trips up more resellers than any other rule.
Dual-Use Items
Some inventory straddles resale and internal use. When you pull tax-free stock out to use in the business, you owe use tax on that item and have to self-report it on your next sales tax return. The resale certificate you signed at purchase actually commits you to this in writing. On mixed orders, identify which items are for resale so the supplier can charge tax on the rest. Covering the whole order with a resale certificate and quietly keeping some items is exactly what triggers penalties in an audit.
Services and Digital Goods
Most states built their resale exemptions around tangible goods, and the treatment of services varies widely. A business that subcontracts labor and resells the finished service can often claim the exemption, but the details differ by state. Software licenses, downloadable content, and streaming subscriptions sit in a similar gray zone. Some states treat digital products like physical goods for resale purposes, others have separate rules, and some don’t tax them at all. If your inventory includes services or digital products, check the specific rules in every state you operate in.
Getting Registered: Seller’s Permits and Nexus
You can’t claim the exemption until you’re registered as a seller in every state where your business has a sales tax obligation. That obligation exists wherever your business has “nexus” — a sufficient connection to trigger the state’s taxing authority.
Nexus used to require a physical footprint: a warehouse, office, or employees in the state. That changed in 2018, when the U.S. Supreme Court ruled in South Dakota v. Wayfair that states can require sales tax collection based on economic activity alone. The South Dakota law at issue applied to sellers who delivered more than $100,000 in goods or services into the state, or completed 200 or more separate transactions there, in a single year.1Supreme Court of the United States. South Dakota v. Wayfair Inc. Every state with a sales tax has since adopted some version of economic nexus.
Thresholds vary. Dollar tests range from $100,000 to $500,000, and a growing number of states have dropped the transaction-count test entirely. Five states impose no statewide sales tax at all: Alaska, Delaware, Montana, New Hampshire, and Oregon, although some Alaska localities do levy local sales taxes.
Registering for a seller’s permit is usually free or close to it. Most states charge nothing; a few charge modest fees, generally under $20. The application asks for the standard information: legal name, address, EIN or Social Security Number, and a description of what you sell. Once approved, the state issues an identification number that goes on every resale certificate you write. Without an active registration number, you cannot legally claim the exemption.
The Resale Certificate
The certificate is the document that makes the exemption work at the register. At a minimum it must include your business name and address, your state-issued permit number, a description of the property being purchased, and a signature affirming the items are for resale.
Blanket vs. Single-Purchase Certificates
Most resellers use blanket certificates. You fill one out once, the supplier keeps it on file, and every subsequent inventory purchase from that supplier is covered without new paperwork. A single-purchase certificate covers only one transaction. Blanket certificates are far more practical for regular supplier relationships, and several states explicitly allow them to remain valid as long as the buyer keeps making recurring purchases.
The Multistate Form
Buying from out-of-state suppliers used to mean tracking down a different form for every state. The Multistate Tax Commission’s Uniform Sales and Use Tax Resale Certificate, a single form accepted by 36 states, lets you list your registration numbers for multiple states on one document.2Multistate Tax Commission.

Resellers operating in many states can also register centrally through the Streamlined Sales and Use Tax Agreement, which offers one electronic registration across member states and lets you file returns and pay tax through a single portal.4Streamlined Sales Tax Governing Board.

Expiration
Most states issue resale certificates that don’t expire as long as your seller’s permit stays active and the business keeps operating. A few states require periodic renewal — Florida is the notable example, requiring renewal each January. Even where certificates don’t technically expire, suppliers often ask for updated documentation every few years for their own audit protection. If your business name changes, your structure changes, or your permit lapses, you’ll usually need to re-register and get a new certificate number rather than simply renewing the old one.
Drop Shipping
Drop shipping tangles the documentation. The reseller takes the order but never touches the product; the supplier ships directly to the end customer. That’s really two transactions: a wholesale sale from supplier to reseller, and a retail sale from reseller to customer.
The wholesale leg qualifies for the resale exemption, but proving it gets complicated when the reseller has no nexus in the delivery state. Most states let the supplier accept the reseller’s home-state registration number on a resale certificate. Roughly ten states are strict about requiring their own state-issued number. In those states, an unregistered reseller may need to register locally, provide an affidavit of no nexus, or pass through the end customer’s exemption certificate. Getting this wrong leaves the supplier collecting tax on a wholesale transaction that should have been exempt, and that cost usually flows back to you.
Marketplace Sales
If you sell through Amazon, eBay, Etsy, or a similar platform, marketplace facilitator laws have taken most of the collection burden off you. Every state with a sales tax now requires the platform itself to collect and remit sales tax on sales made through its system.
That doesn’t erase your obligations. The platform only covers sales made through it. Anything you sell from your own website, at trade shows, from a physical location, or through any other channel is still yours to collect and remit. You still need a seller’s permit in states where you have nexus, and you still need resale certificates for inventory purchases no matter where the finished goods eventually sell. A few states waive the permit requirement for sellers who exclusively sell through a tax-collecting marketplace, but the first sale outside the platform brings the full registration and collection obligation back.
Penalties and Audit Risk
State auditors focus heavily on resale certificate abuse because it’s one of the most common forms of sales tax evasion. The classic scheme is simple: hand a resale certificate to a supplier for items that are really for personal consumption or business use, and pocket the tax. Auditors look for patterns like exemption claims on categories of goods that don’t match the business, or exempt purchase volumes that far outrun reported sales.
Penalties stack. At a minimum you owe the back tax plus interest from the date of the original purchase. Most states add a percentage-based penalty on the unpaid tax. When misuse is deemed intentional or fraudulent, the penalties escalate, and some states classify knowing misuse of a resale certificate as a criminal misdemeanor. Even a modest amount of improper exempt purchases can turn into a substantial bill.
Recordkeeping is your protection. Keep documentation showing that every item purchased tax-free was resold or built into something that was sold. When you pull stock for business use, self-assess the use tax and report it on the next return. Auditors approach resale claims with a presumption of taxability, meaning the burden is on you to prove each exemption was legitimate. Records that trace each exempt purchase to a corresponding sale are what separate a clean audit from an expensive one.
