Resale certificates: how buyers and sellers should keep the documentation organized

A resale certificate can support a tax-exempt purchase for resale when state rules permit. Sellers should validate and retain customer certificates, while buyers should use them only for qualifying purchases.

A resale certificate is transaction support, not a general tax exemption

Businesses that purchase goods for resale can often provide state-specific resale documentation to suppliers, subject to the rules of the jurisdictions involved. The certificate supports why the seller did not collect tax on qualifying sales.

It should not be used for ordinary business purchases that are consumed by the buyer.

Sellers should maintain a certificate file by customer

Keep the customer's legal name, state, certificate or permit number, effective date, signed form, product relationship, and expiration or renewal information when applicable.

Link the certificate to the customer account so billing staff do not rely on an old email or verbal statement.

Buyers should control who can issue certificates

Limit certificate issuance to staff who understand what the company buys for resale. Keep copies of every certificate provided to vendors and the state accounts that support them.

Review purchases coded as tax-exempt if the business begins using those goods internally.

Revalidate after material changes

Ownership changes, entity changes, new states, expired permits, or changes in product use can affect whether existing documentation remains appropriate.

A disciplined certificate archive makes sales-tax audits and vendor questions much easier to answer.

Frequently asked questions

Questions buyers usually ask

What is a resale certificate used for?

It can document that a qualifying purchase is being made for resale so the seller may not need to collect sales tax on that purchase under applicable state rules.

Should a seller keep customer resale certificates?

Yes. Sellers should retain valid documentation according to applicable state rules so they can support why tax was not collected.
