A California resale certificate documents that a buyer is purchasing specified tangible personal property for resale in the regular course of business. When a seller accepts a valid certificate in good faith and on time, the seller generally does not collect sales tax on that documented sale. It is not a blanket exemption for the buyer’s purchases: items bought for the buyer’s own use are not purchases for resale.
California’s tax authority is the California Department of Tax and Fee Administration (CDTFA). The state layers district taxes on top of its statewide rate, so the applicable rate for a taxable sale depends on the delivery address down to street level. That rate question is separate from whether a particular sale is properly documented as a resale. Sales Tax Compliance USA is a people-led, done-for-you service that helps ecommerce and cross-border sellers manage these obligations.
What a California resale certificate does
A resale certificate is a written statement from a purchaser to a seller identifying property the purchaser intends to resell. It gives the seller documentation for treating that particular sale as a sale for resale rather than collecting tax from the purchaser at checkout. The purchaser generally accounts for tax when the property is later sold at retail, unless another applicable rule changes the treatment.
The certificate applies to the property described in it and the stated resale purpose. It does not make every purchase by the business tax-free. If the purchaser uses, consumes, or keeps an item rather than reselling it, the purchase may not qualify for resale treatment; the purchaser should review its tax obligations with the CDTFA or a qualified adviser.
How to get a California resale certificate
California does not issue a buyer a general resale certificate number or require buyers to obtain a special resale certificate from the CDTFA. A purchaser prepares a certificate for its supplier. The CDTFA provides form CDTFA-230, General Resale Certificate, as an optional form, but a qualifying written document such as a letter or purchase order can also serve if it contains the required information.
A seller’s permit is a separate matter. If your business is required to hold a California seller’s permit, apply through the CDTFA online services portal. Whether you need a permit depends on your activities and circumstances; do not assume that a resale certificate substitutes for registration. Check the CDTFA’s current permit guidance or ask us to review your situation.
What a valid certificate must include
A California resale certificate should identify the purchaser by business name and address, include the purchaser’s California seller’s permit number or explain why the purchaser is not required to hold one, describe the property being purchased, and state that the property is being purchased for resale. The statement must use the words “for resale”; terms such as “exempt” or “nontaxable” alone do not establish a resale purchase.
The document should also be dated and signed by the purchaser, an employee, or an authorized representative. The CDTFA says an otherwise valid certificate is not invalid solely because it is undated, but including the date is the practical choice. Use a description specific enough to connect the certificate to the goods being bought, and keep the certificate consistent with the actual transaction.
When sellers can accept a resale certificate
A seller may accept a certificate when the buyer is purchasing the described property for resale in the regular course of business and the certificate is complete enough to support that treatment. The seller must take it in good faith and in a timely manner. Under CDTFA guidance, a certificate is timely if received before billing, within the seller’s normal billing and payment cycle, or at or before delivery.
Review the certificate rather than treating it as a formality. Check that the buyer’s business and permit information make sense, the goods fit the stated resale purpose, and the document is signed and contains the required resale language. Where appropriate, use the CDTFA’s permit verification service to check permit information. If the facts do not support resale treatment or the certificate is incomplete, ask the buyer to correct or substantiate it and determine whether tax must be collected.
Resale certificates and other sales tax exemption certificates
A resale certificate is one specific kind of sales-tax documentation: it supports a claim that goods are being bought for resale. An exemption certificate documents a different basis for an exempt or partially exempt transaction, such as a qualifying exemption recognized under California law. The required form and supporting facts depend on the particular exemption; a resale certificate cannot be used as a general-purpose exemption certificate.
For example, a buyer purchasing inventory to resell should document the resale purpose. A buyer claiming a separate statutory exemption should provide the certificate or other documentation required for that exemption. Sellers should identify the actual reason tax is not being charged and retain the corresponding evidence. If the transaction does not clearly fit a resale or exemption rule, confirm its treatment with the CDTFA or have us review it.
How long a California resale certificate remains valid
California resale certificates do not have a fixed expiration period stated in the CDTFA guidance cited here. A certificate remains in effect until revoked in writing. That does not mean a seller should rely indefinitely on a certificate when the buyer, goods, or business circumstances have changed.
Keep the certificate linked to the customer and the transactions it supports. Review it when the customer’s business details or purchasing pattern changes, when the goods no longer appear consistent with resale, or when you receive information that calls the stated purpose into question. Ask for an updated certificate when needed to support the current facts.
Records, misuse, and invalid certificates
Keep certificates with the related invoices, orders, customer details, and any permit checks or correspondence that explain your decision. CDTFA guidance says businesses holding a seller’s permit or other CDTFA license or permit must maintain records to verify tax and fee reporting, and generally keep business records for at least four years. Organize records so you can retrieve the certificate and connect it to the sale if the CDTFA asks about the transaction.
Accepting a certificate that is incomplete, untimely, or inconsistent with the transaction can leave the seller exposed to tax, interest, or penalties under applicable law. A buyer who uses resale treatment for goods it actually consumes or keeps may also have tax obligations. Do not accept a certificate simply because a customer supplied one: investigate obvious inconsistencies, document your review, and seek guidance when the facts are uncertain.
Out-of-state sellers and California resale purchases
An out-of-state seller making sales to California customers may encounter California resale certificates when a California buyer purchases goods for resale. CDTFA guidance states that, once registered where required, an out-of-state retailer may accept a timely resale certificate in good faith to document a qualifying sale. The certificate may be in different written forms, but it still needs the required purchaser, permit-or-explanation, property description, resale statement, date, and signature information.
Do not confuse a resale purchase with a sale shipped out of California. A sale’s tax treatment can depend on the actual delivery and transaction facts, as well as the seller’s California obligations. California’s district taxes make address-level sourcing important for taxable sales. Cross-border sellers should review registration, collection, and documentation together; the exact position depends on the transaction and business circumstances, so confirm it with the CDTFA or ask us to check it for you.

How California resale documentation differs from other common transaction treatments
| Transaction or claim | What the documentation supports | What the seller should check |
|---|---|---|
| Goods bought for resale | The described goods are purchased for resale in the regular course of business. | Buyer identity and permit number or reason no permit is required; goods description; “for resale” statement; signature; timely, good-faith acceptance. |
| Goods bought for the purchaser’s own use | No resale treatment is supported merely because the purchaser operates a business. | Whether the purchaser will consume, use, or keep the goods; do not rely on a resale certificate for a personal-use or business-use purchase. |
| Separate statutory exemption or partial exemption | A specific exemption basis, not the general intention to resell goods. | The applicable exemption requirements and certificate or other evidence for that claim; do not substitute a resale certificate. |
| Taxable California sale delivered to a customer | The sale is taxable unless a valid exclusion, exemption, or resale treatment applies. | Delivery address and applicable district tax rate; California rates vary by location, so determine the rate using the actual delivery address. |
| Sale by an out-of-state retailer to a California buyer for resale | A qualifying resale purchase documented for California purposes. | Whether California registration is required, whether the certificate is timely and accepted in good faith, and whether the transaction facts match the certificate. |
Frequently asked questions
What is a California resale certificate?
It is a written statement a purchaser gives a seller to document that specified property is being bought for resale in the regular course of business. A seller that accepts a valid certificate in good faith and on time generally does not collect sales tax on that documented sale. It does not cover goods the purchaser buys for its own use.
How do I get a California resale certificate?
You prepare one for your supplier; the CDTFA does not issue buyers a general resale certificate number. You may use the optional CDTFA-230 General Resale Certificate or another written document containing the required information. If your business needs a California seller’s permit, apply through the CDTFA online services portal; the permit is separate from the certificate.
What is the difference between a resale certificate and a sales tax exemption certificate?
A resale certificate documents that goods are being purchased for resale. An exemption certificate documents a different qualifying exemption or partial exemption under applicable law. Use documentation that matches the actual reason tax is not being charged; a resale certificate is not a general exemption certificate.
Does California have a resale certificate form?
Yes. The CDTFA provides CDTFA-230, General Resale Certificate, as an optional form. California does not require that specific form: another written document can qualify if it includes the required information and supports the transaction.
What information must a California resale certificate include?
It must identify the purchaser by name and address, provide the purchaser’s seller’s permit number or explain why the purchaser is not required to hold one, describe the property, and state that it is being purchased “for resale.” It should also be dated and signed by the purchaser or an authorized person; the CDTFA says an otherwise valid certificate is not invalid solely because it is undated.
Do I need a seller’s permit to issue a California resale certificate?
Not in every case. A purchaser who is not required to hold a California seller’s permit must explain on the certificate why no permit is required instead of providing a permit number. Whether your business must obtain a permit depends on its activities; check current CDTFA guidance or ask us to review your circumstances.
How long is a California resale certificate valid?
The CDTFA’s regulation says a resale certificate remains in effect until revoked in writing; it does not set a fixed expiration period in that rule. Sellers should still review certificates when customer details, goods, or purchasing circumstances change and request updated documentation when needed.
When can a seller accept a resale certificate in California?
The seller can accept it when the buyer is purchasing the described property for resale, the certificate supports that purpose, and the seller accepts it in good faith. It is timely if received before billing, within the seller’s normal billing and payment cycle, or at or before delivery. If the certificate or transaction raises doubts, investigate and determine whether tax must be collected.
