A resale certificate is the document a buyer gives a supplier to show that goods are being purchased for resale, not for the buyer's own use. When the certificate is valid for the transaction, the supplier can treat the sale as a resale sale and avoid charging sales tax on that purchase.
The basic idea is simple: sales tax is supposed to be collected from the final customer. A resale certificate helps keep the same item from being taxed once when a reseller buys it and again when the reseller sells it.

How it works
In a typical resale transaction, a supplier sells inventory to a retailer, ecommerce seller, or dropshipper. The buyer gives the supplier a completed resale certificate. The supplier keeps that certificate in its records, and the buyer later collects any required sales tax from the final customer.
The certificate is not usually a magic approval from the state. It is documentation that supports the supplier's decision not to charge tax on the wholesale purchase.
What it usually includes
Most resale certificates ask for a few familiar details:
- The buyer's business name and address.
- The seller or supplier's name.
- A sales tax permit, license, or registration number.
- A description of the items being bought for resale.
- A signed statement that the purchase is for resale.
There is no single national resale certificate. Some states publish their own forms, while many vendors also accept multistate forms for eligible transactions.
Resale certificate vs. seller's permit
A seller's permit is your registration with a state to collect and remit sales tax. A resale certificate is the document you give to suppliers so you can buy qualifying inventory tax-free.
In many states, the resale certificate needs a valid permit or registration number. That is why the permit often comes first, and the certificate follows when you are ready to buy inventory. For a fuller breakdown, see resale certificate vs. seller's permit.
When you need one
You generally need a resale certificate when you are buying goods that you plan to resell, especially if a supplier asks for tax-exemption documentation before selling to you tax-free.
Dropshippers often need one because there are two transactions in the chain: the supplier sells to the dropshipper, and the dropshipper sells to the customer. The resale certificate helps document the first sale. Read more in do dropshippers need a resale certificate?.
Rules to keep straight
- Use resale certificates only for items you genuinely intend to resell.
- Keep copies of certificates you send to suppliers.
- Expect rules to vary by state and by vendor.
- Use a state-specific form when a state or supplier requires one.
- Consider a multistate certificate only where it is accepted for the transaction.
Practical takeaway
A resale certificate is paperwork with a very practical job: it tells your supplier why a purchase should be treated as inventory for resale. Keep the certificate accurate, match it to the transaction, and do not use it for supplies, equipment, or personal purchases.
