To fill out a California resale certificate, download Form CDTFA-230 from the CDTFA, then enter your business’s legal name, mailing address, and California seller’s permit number exactly as they appear in state records, name the vendor you’re buying from, describe the property you intend to resell and the nature of your business specifically enough that both fit together, and sign and date the form before handing it to the seller. The whole thing takes about five minutes once you have your permit number in front of you, but each field carries weight during an audit, so none of them are throwaways.
What to Have Ready Before You Start
Three things need to be in front of you: your business’s legal name as registered with the state, the address the California Department of Tax and Fee Administration has on file, and your California seller’s permit number. State law requires the certificate to carry that permit number along with your name, address, and a description of what your business sells.1California Legislative Information. California Revenue and Taxation Code Section 6093 If you haven’t been issued a seller’s permit yet, you can’t issue a valid resale certificate; apply through the CDTFA first.
Form CDTFA-230 is a single-page PDF on the CDTFA website.2California Department of Tax and Fee Administration. General Resale Certificate CDTFA-230 Complete it digitally or print it and fill it in by hand. Either is fine.
Walking Through Each Field
Purchaser Name and Address
The top of the form is for you, the buyer. Write your full legal business name and mailing address, and make them match your CDTFA records exactly. A mismatch is the kind of thing an auditor flags, and a careful seller may reject the form on the spot.
Seller’s Permit Number
Enter the permit number the CDTFA assigned when you registered.2California Department of Tax and Fee Administration. General Resale Certificate CDTFA-230 Without it, the certificate is missing a required element under Regulation 1668, and the seller has no obligation to treat the sale as tax-free.3California Department of Tax and Fee Administration. Regulation 1668 – Sales for Resale
Vendor Name
Field 3 is where you name the seller you’re buying from for a single transaction. If you plan to use the form as a blanket certificate covering all qualifying future purchases from the same vendor, use field 4 instead, which contains the language covering ongoing purchases.
Description of the Property
Field 5 is where most people either rush or freeze. Describe what you’re buying for resale specifically enough that someone reading the certificate years later can see the items fit your business. A clothing retailer might write “men’s and women’s apparel.” A restaurant supply company might write “commercial kitchen equipment and smallwares.” Terms like “merchandise” or “various goods” are too vague and invite scrutiny.
Description of Your Business
The form asks you to describe what your business does. Make it obvious why the items on the certificate are things you would resell. “Retail flower shop selling arrangements and plants to consumers” clearly matches wholesale flower purchases. A thin description forces the seller to take your word for it and leaves both of you exposed if the CDTFA questions the transaction.
Signature and Date
Sign and date at the bottom. The signature can come from the purchaser, an employee, or an authorized representative, with a printed name and title.2California Department of Tax and Fee Administration. General Resale Certificate CDTFA-230 An unsigned certificate is not valid. Regulation 1668 notes that an undated certificate isn’t automatically invalid for that reason alone, so the signature carries more weight than the date, but fill in both.3California Department of Tax and Fee Administration. Regulation 1668 – Sales for Resale
Single-Purchase or Blanket
The form gives you a choice. Field 3 covers one transaction with one vendor. Field 4 turns the certificate into a blanket certificate that applies to all qualifying purchases from that same vendor going forward. If you buy from a supplier regularly, the blanket option saves you from filling out a new form for every order.
A blanket certificate stays in effect until you revoke it in writing.3California Department of Tax and Fee Administration. Regulation 1668 – Sales for Resale There’s no built-in expiration. Convenient for long-term supplier relationships, but the certificate keeps working even if your business changes direction. If you stop reselling the type of goods it covers, revoke it so you don’t accidentally make tax-free purchases for items you now consume internally.
What the Certificate Does and Doesn’t Cover
This is where businesses get themselves in trouble. A resale certificate only covers property you intend to resell. Anything your business uses up, consumes, or keeps for its own operations doesn’t qualify. Office supplies, cleaning products, tools, furniture, computers, and business equipment are taxable purchases for the business using them, even if that business holds a seller’s permit.4California Department of Tax and Fee Administration. Table of General Guidelines
CDTFA guidelines spell this out across dozens of industries. A restaurant owes tax on cleaning supplies and office equipment but can buy food ingredients for resale tax-free. An auto repair shop can use a resale certificate for parts it installs and bills to customers, but not for its own tools or office supplies. Service providers like accountants, doctors, and janitorial companies are generally treated as end users of everything they buy, so their purchases are almost always taxable.4California Department of Tax and Fee Administration. Table of General Guidelines
The general rule: if the item goes out the door as part of what you sell to customers, it qualifies. If it stays behind and helps you run the business, it doesn’t.
Giving It to the Seller
Hand the completed certificate to your vendor. You do not file it with the CDTFA or any state agency. It’s a private document between buyer and seller. Delivery can be a physical copy at the point of sale, a signed PDF by email, or an upload through a vendor portal. The method is up to you, but timing matters. Regulation 1668 considers the certificate timely if you provide it before the seller bills you, within the seller’s normal billing cycle, or before delivery of the goods.3California Department of Tax and Fee Administration. Regulation 1668 – Sales for Resale
What Happens If You Use Resale Items in the Business
Plans change. You buy inventory with a resale certificate, then your business uses some of it internally instead of selling it. When that happens, you owe use tax on those items. Use tax applies to tangible property purchased tax-free and then stored, used, or consumed in California rather than resold. If you hold a seller’s permit, report the use tax on your regular sales and use tax return for the period when you first used or consumed the item.
This comes up more often than people expect. A retailer who pulls merchandise off the shelf for office use, a restaurant that takes cleaning supplies from resale stock for the kitchen, or a car dealer that puts a vehicle from inventory into the company fleet all owe use tax on those items. The amount is based on the purchase price at the same combined rate that would have applied as sales tax.
Keeping the Certificate on File
Both parties need to hold onto it. California Regulation 1698 requires sales tax records, including resale certificates, to be preserved for at least four years.5California Department of Tax and Fee Administration. Regulation 1698 – Records If you’re under audit, keep records covering the audit period until it’s complete, even if that stretches past four years.6California Department of Tax and Fee Administration. Tax Guide for Home-Based Businesses – Managing Your Sales
Digital copies are fine. The CDTFA doesn’t require paper originals. Just make sure the electronic records are complete and accessible. If you use a point-of-sale system that overwrites data, Regulation 1698 warns that you need to transfer and preserve that data before it’s purged.5California Department of Tax and Fee Administration. Regulation 1698 – Records
The Cost of Getting It Wrong
Using a resale certificate to avoid sales tax on something you don’t intend to resell carries civil and criminal consequences. Under Revenue and Taxation Code Section 6094.5, knowingly issuing a false resale certificate to avoid paying tax is a misdemeanor.7California Department of Tax and Fee Administration. Sales and Use Tax Law – Section 6094.5 A conviction can carry a fine between $1,000 and $5,000, up to one year in county jail, or both.8California Department of Tax and Fee Administration. Sales and Use Tax Law – Chapter 10
On the civil side, anyone who uses a resale certificate for personal gain or to evade tax owes the full tax that should have been paid plus a penalty of 10 percent of the tax or $500, whichever is greater, on each purchase.7California Department of Tax and Fee Administration. Sales and Use Tax Law – Section 6094.5 The CDTFA doesn’t need to prove you acted maliciously. If you gave a resale certificate for items you knew you wouldn’t resell, the penalty applies. That is why the property description and business description on the form are worth taking seriously the first time.
