How to Get a Resale Certificate in California
How to Get a Resale Certificate in California
If you're buying products to resell in California, you shouldn't be paying sales tax on those purchases. That's the buyer's job, not yours. A California resale certificate is how you prove to your supplier that the sale is tax-exempt because you'll be collecting sales tax from the end customer instead.
The good news: getting a resale certificate in California is free and doesn't require a separate application. It flows directly from your seller's permit. Here's exactly how it works and how to get set up correctly.

What Is a California Resale Certificate?
A resale certificate (sometimes called a reseller's certificate or resale exemption certificate) is a document you give to your vendor or supplier that says: "I'm buying this item to resell it, so don't charge me sales tax." The tax obligation shifts to the final sale. When you sell to your customer, you collect and remit the sales tax instead.
In California, the resale certificate is governed by the California Department of Tax and Fee Administration (CDTFA). There is no standalone "resale license" you apply for. Your authority to issue resale certificates comes from holding a valid California seller's permit.
Common terms you'll see used interchangeably (they all refer to the same concept in California):
- Resale certificate
- Resale license California
- California wholesale permit
- Reseller's permit
- Tax exemption certificate
Who Needs a California Resale Certificate?
You need to use a resale certificate any time you purchase goods that you intend to resell to customers in the ordinary course of your business. Typical examples include:
- Retailers buying inventory from wholesalers
- E-commerce sellers purchasing products to list online
- Restaurants buying food ingredients they'll sell prepared to customers
- Contractors purchasing materials that become part of a product they sell (rules here are specific; consult a CPA)
- Wholesalers buying goods to resell to other businesses
- Drop shippers arranging sales of goods they never physically handle
If you're buying supplies you'll use in your business (office chairs, computers, cleaning products), those are not for resale and you cannot use a resale certificate for those purchases. Misusing a resale certificate to avoid sales tax on non-resale items is tax fraud under California law.
Step 1: Register for a California Seller's Permit
Before you can issue a resale certificate to a vendor, you need a valid California seller's permit. This is issued by the CDTFA and is completely free to obtain.
You can register online at the CDTFA's website: cdtfa.ca.gov
How to apply for your seller's permit:
- Go to CDTFA Online Services and click "Register a New Business Activity"
- Select "Seller's Permit" as your account type
- Enter your business information: legal name, business address, entity type (sole proprietor, LLC, corporation, etc.)
- Provide your Social Security Number or FEIN (Federal Employer Identification Number)
- Describe the products you'll be selling
- Estimate your monthly sales volume
- Submit the application
In most cases, you'll receive your seller's permit number immediately upon completing the online registration. A physical permit is typically mailed within 2–4 weeks.
Important: If your business has multiple locations in California, you'll need a separate seller's permit for each physical location.
Step 2: Fill Out the Resale Certificate Form
Once you have your seller's permit number, you can issue resale certificates to your suppliers. California does not require a specific state-issued form. Instead, you provide a completed resale certificate to your vendor that includes the required information.
The CDTFA provides a standard resale certificate template: CDTFA-230. You can download it from cdtfa.ca.gov/formspubs/cdtfa230.pdf
Required information on the resale certificate:
- Your business name and address
- Your California seller's permit number
- A description of the items you're purchasing
- A statement that the items are being purchased for resale
- Your signature and the date
- The vendor's name and address (in some cases)
You can issue a blanket resale certificate to a vendor you purchase from regularly. This covers all purchases of the same type of goods from that vendor without needing to fill out a new form every time. Just note it as a blanket certificate on the form.
Step 3: Provide the Certificate to Your Supplier
Hand the completed resale certificate to your supplier before or at the time of purchase. Your supplier is required to keep this certificate on file. It relieves them of the obligation to collect sales tax from you. The responsibility to collect tax shifts to you when you make the final sale.
Suppliers are not required to accept your resale certificate, though most legitimate wholesale vendors will. If a supplier refuses to accept it, you may pay the tax upfront and request a refund from the CDTFA, though that's a more complicated process.
What If You Don't Have a Seller's Permit Yet?
In limited circumstances, the CDTFA allows a business to use a resale certificate without a seller's permit if they can demonstrate they are "engaged in the business" of selling the type of goods being purchased. However, this is a narrow exception and puts more liability on both you and your vendor. The practical recommendation is to get your seller's permit first. It's free and takes 15 minutes online.
California Resale Certificate Rules You Need to Know
What Can and Cannot Be Purchased with a Resale Certificate
| Purchase Type | Resale Certificate Valid? |
|---|---|
| Inventory you'll sell to customers | ✅ Yes |
| Raw materials that become part of a product you sell | ✅ Yes (in most cases) |
| Office supplies for internal use | ❌ No |
| Equipment used in your business | ❌ No |
| Shipping supplies (boxes, tape) used to ship your products | ❌ No (generally) |
| Food ingredients resold in a restaurant | ✅ Yes |
Out-of-State Sellers Selling to California Customers
If you're an out-of-state seller with economic nexus in California (generally over $500,000 in California sales in the prior or current calendar year), you must register with the CDTFA and collect California sales tax. The resale certificate rules still apply if you're purchasing inventory.
Accepting Resale Certificates from Your Buyers
If you're a wholesaler and a customer provides you with their resale certificate, you must:
- Verify their seller's permit number is valid (you can check at CDTFA's permit verification tool)
- Keep the certificate on file for at least 4 years
- Use good faith. If the certificate appears fraudulent or the items don't match the buyer's business, you may still be liable for the tax.
Record-Keeping Requirements
California requires you to keep copies of all resale certificates you receive for a minimum of 4 years. The CDTFA can audit your records, and if you cannot produce a valid resale certificate for a tax-exempt sale, you may owe the back taxes plus interest and penalties.
How to Verify a California Seller's Permit Number
If a customer gives you a resale certificate and you want to verify their seller's permit is legitimate, use the CDTFA's online verification tool:
👉 CDTFA Permit Verification, search under "Verify a Permit, License, or Account"
You'll need the business name or permit number. If the permit doesn't appear in the system or is listed as inactive, do not accept the resale certificate without further verification.
Common Mistakes to Avoid
- Using a resale certificate for non-resale items. This is tax fraud. The CDTFA audits this and penalties can be severe.
- Forgetting to get a seller's permit before issuing certificates. Your certificate is only valid if you're registered with the CDTFA.
- Not keeping records. Four years, minimum. Keep digital copies as backup.
- Issuing a certificate for items you're unsure you'll resell. If you end up using items yourself instead of reselling them, you owe use tax on those items.
- Assuming out-of-state purchases are automatically exempt. California use tax may apply even on purchases made outside California if the goods are used in California.
Costs Summary
| Item | Cost |
|---|---|
| California Seller's Permit | Free |
| CDTFA-230 Resale Certificate Form | Free (downloadable PDF) |
| CDTFA Online Account Registration | Free |
The California resale certificate process has zero filing fees. The only costs involved are your time and, if applicable, professional fees if you hire a CPA or business attorney to help structure your tax compliance process correctly. This is worth considering if you're running a high-volume operation.
Frequently Asked Questions
Is a California resale certificate the same as a wholesale license?
They're closely related but not identical. In California, there is no separate "wholesale license." Your seller's permit is what authorizes you to issue resale certificates and buy goods tax-free for resale. Some people use "california wholesale permit" to mean the same thing as a seller's permit used in a wholesale buying context.
Does my resale certificate expire?
California resale certificates themselves do not have a set expiration date. However, your seller's permit can become inactive if your business closes or you don't file returns. Always make sure your underlying seller's permit is current and active.
Can I use a resale certificate from another state in California?
No. California does not accept resale certificates from other states. If you're purchasing from a California vendor, you need a California seller's permit and a California resale certificate.
What if I only sell occasionally, do I still need a seller's permit?
If you make three or more sales in a 12-month period, California requires you to hold a seller's permit. For occasional sellers (fewer than three sales per year), you can file as a "one-time" or "occasional" seller, but you cannot issue resale certificates without a permit.
Next Steps After Getting Your Resale Certificate
Getting your resale certificate squared away is one piece of the larger puzzle of setting up your California business properly. Once you have your seller's permit and resale certificate process in place, make sure you've also addressed:
- Choosing and registering your business entity (LLC, corporation, sole proprietorship) with the California Secretary of State
- Obtaining any local business licenses required by your city or county
- Setting up a separate business bank account to keep finances clean for tax purposes
- Understanding your California sales tax filing schedule (monthly, quarterly, or annually depending on your sales volume)
For complex inventory, drop-shipping arrangements, or multi-state sales tax situations, consult a California-licensed CPA with experience in sales tax compliance. The CDTFA also offers free taxpayer assistance. You can reach them at cdtfa.ca.gov or by calling 1-800-400-7115.
