California rules in plain English

In California, the usual form is CDTFA-230, the General Resale Certificate, from the California Department of Tax and Fee Administration (CDTFA). CDTFA does not require that exact form. Any document works if it has all the required parts. Enter your California seller's permit number. If you are not required to hold a California seller's permit, for example because you make no sales in California, you must explain why instead. Describe what you sell and the items you are buying for resale. The certificate must be signed by you, your employee or an authorized representative, and dated. One blanket certificate can cover repeat purchases from the same supplier. It stays in effect until you revoke it in writing. Your supplier should get it before billing you or by delivery, and can check your permit online with CDTFA. If you use an item yourself instead of reselling it, you owe use tax on its purchase price. If you knowingly misuse a resale certificate to avoid tax, you owe the tax plus a penalty of 10 percent of the tax or $500, whichever is more, for each purchase. Misuse can also be a misdemeanor.

More California facts

  • A valid California resale certificate must show the purchaser's name and address, its seller's permit number (or an explanation of why it is not required to hold one), a description of the property, a statement that the property is bought for resale, the date, and the signature of the purchaser, its employee or authorized representative.

  • On a drop shipment to a California customer, a drop shipper that is engaged in business in California is treated as the retailer, and a resale certificate from an out-of-state true retailer only helps if it shows a valid California seller's permit, use tax registration or qualifying marketplace sale.

  • The resale certificate covers tangible personal property bought for resale, including property that becomes an ingredient or component of an item manufactured for resale. It is not an exemption certificate; other exemptions use their own certificates. Source

What a California resale certificate must include

  • The buyer's legal name, business address, and California seller's permit number.
  • The seller's name and address.
  • A description of the property being purchased for resale, or for a blanket certificate a general description such as "All tangible personal property purchased for resale".
  • A statement that the items will be resold in the ordinary course of business, signed and dated by the buyer.

Using your California certificate

  1. Confirm the purchase is genuinely for resale. Using a certificate for supplies or equipment you consume is the most common audit finding.
  2. Give the vendor the signed certificate before or at the time of the sale; a certificate produced after the fact is often rejected.
  3. Issue one blanket certificate per vendor and keep a copy for your records.
  4. Expiration: Valid until revoked. Reissue the certificate whenever your permit number, name, or address changes.

California resale certificate FAQ

What form do I use for a California resale certificate?
The California Department of Tax and Fee Administration publishes Form CDTFA-230, the General Resale Certificate, but California does not require it. Any certificate with the required elements is accepted. Our generator fills in the California form for you. You get a signed PDF with your business, permit, and purchase details.
Does California accept the MTC uniform resale certificate?
Yes. California accepts the Multistate Tax Commission's Uniform Sales and Use Tax Certificate, which is convenient when you buy from vendors in several states.
Can an out-of-state business use a resale certificate in California?
Generally not. California does not substitute another state's registration number for a California seller's permit number. A purchaser not required to hold a California permit (for example an out-of-state retailer that makes no sales in California) may instead give a sufficient explanation of why it is not required to hold one. For drop shipments to California customers, Regulation 1706 treats a drop shipper engaged in business in California as the retailer, and a resale certificate from a true retailer without a California seller's permit (or use tax registration or qualifying marketplace status) does not relieve it.
Can I give a vendor one blanket resale certificate in California?
Yes. A blanket certificate in California covers every qualifying purchase from that vendor going forward, typically described as "All tangible personal property purchased for resale".
How long is a California resale certificate valid?
A resale certificate remains in effect until revoked in writing. A blanket certificate does not cover a purchase that the buyer's purchase order marks as taxable.
What happens if I misuse a California resale certificate?
A purchaser who uses property bought under a resale certificate for anything other than resale (or demonstration and display while held for sale) owes use tax on the purchase price. A person who knowingly misuses a resale certificate for personal gain or to evade tax is liable, for each purchase, for the tax plus a penalty of 10 percent of the tax or $500, whichever is more. Knowingly giving a resale certificate for an item the person will not resell before use can also be a misdemeanor.
When can a California seller rely on a resale certificate?
A seller that timely accepts a resale certificate in good faith does not owe the tax on that sale. Timely means before the seller bills the buyer, within the seller's normal billing and payment cycle, or at or before delivery. Without evidence to the contrary, a seller is presumed to have acted in good faith if the certificate has all essential elements and appears valid on its face. Sellers can check a permit online or by calling 1-888-225-5263.
