How to Use the California Resale Certificate
The short answer. The California Resale Certificate (Form CDTFA-230) is the document a business gives a supplier to buy goods for resale without paying California sales tax. The buyer fills in and signs the California Resale Certificate and gives it to the seller. California publishes a form, but any document that carries the information the state requires is accepted.

Who May Give a Resale Certificate in California
A buyer that is not required to register in California may give the California Resale Certificate with a written statement in place of a registration number. If you are not required to hold a California seller's permit, for example because you make no sales in California, you write on the certificate a sufficient explanation of why you are not required to hold one, in place of the permit number.
The buyer fills in and signs the California Resale Certificate and gives it to the seller.
Which Documents Are Accepted
California publishes a form, but any document that carries the information the state requires is accepted.
The Multistate Tax Commission lists California among the states that accept its uniform resale certificate, with conditions. The Commission's notes for California say: California accepts it only as a resale certificate, not as an exemption certificate, and only under the rules of Regulation 1668.
We have not confirmed whether California accepts the Streamlined Sales Tax Certificate of Exemption; check with the California Department of Tax and Fee Administration.
What the certificate must contain is set by California law, cited in the sources.
How Long It Lasts
The California Resale Certificate does not expire.
One blanket certificate may cover repeat purchases from the same seller.
For Sellers Who Accept One
Under California's law, a seller that takes a resale certificate in good faith is relieved of liability for the tax on that sale.
The state's general sales tax records period is at least 4 years.
Worth Knowing in California
The certificate must be given to the seller before you are billed, within the seller's normal billing and payment cycle, or at or before delivery. A certificate taken later is not retroactive; the seller is then relieved only if it shows the goods were in fact resold (Reg. 1668(e)).

Frequently Asked Questions
This guide is general information, not legal or tax advice, and reading it does not create an attorney-client relationship. It reports what each state's tax agency, or the multistate bodies' published notes, say about the certificate a buyer gives a supplier when it buys goods for resale, with the sources this page cites. It cannot tell you whether your own purchase qualifies: that turns on what you buy, whether you resell it, and where you are registered, and a certificate given for a purchase that does not qualify can leave the buyer owing the tax. Confirm your own position with the tax agency named on this page before you give or accept one.
