How to Apply for a Resale License in California: CDTFA Portal and Costs

To apply for a resale license in California, register online with the California Department of Tax and Fee Administration (CDTFA) for what the state officially calls a Seller’s Permit. The permit is free, the application is electronic, and most applicants finish in one sitting. Once issued, it lets you collect sales tax from customers and, just as importantly, issue resale certificates to your suppliers so you can buy inventory without paying sales tax at the register.¹

Do You Need a Seller’s Permit

If you sell or lease tangible personal property in California, you generally need one, even if you only sell occasionally.¹ Storefront, home office, online shop, weekend booth — the rule is the same. And you need a separate permit for each physical location where you negotiate sales with customers.²

Out-of-State and Online Sellers

If you’re located outside California but sell goods for delivery into the state, you have a registration obligation once your combined sales into California exceed $500,000 in the current or preceding calendar year. That threshold includes sales made through marketplace facilitators like Amazon or Etsy.³ If you cross that line and make any non-facilitated sales (through your own website, say), register with the CDTFA for a Certificate of Registration – Use Tax.

One exception matters here: if every single one of your California sales is handled by a marketplace facilitator that is registered with the CDTFA, you are not required to hold your own Seller’s Permit or Certificate of Registration.³ The facilitator collects and remits the tax for you. Make even one sale off the platform and that exemption disappears.

Temporary Sellers

Flea markets, swap meets, and special events don’t get you out of the requirement. If you have no permanent business location, the CDTFA issues a temporary seller’s permit covering a selling period of 90 days or less at one location.⁴ You’ll also need to give your information to the event operator, typically on CDTFA Form 410-D.

What to Gather Before You Start

The online application is straightforward but stalls fast if you don’t have your information in front of you. The portal validates entries in real time, so a mistyped ID number can flag your application for manual review. Collect the following before you begin:⁵

A government-issued photo ID. The CDTFA accepts a California driver’s license, state ID card, U.S. passport, military ID, permanent resident card, tribal-issued photo ID, Matricula Consular ID, and several others. Enter the ID number, issue date, and expiration date exactly as they appear.
Your Social Security Number or Individual Taxpayer Identification Number if you’re an individual applicant.
A Federal Employer Identification Number (FEIN) if you’re registering as a partnership, corporation, LLC, or other entity.
Your California Secretary of State entity number if you’re a corporation, LLC, or limited partnership.
Names and addresses of your suppliers. The CDTFA wants to see where you source inventory.
Contact information for personal references who can vouch for your identity and business intent.
Your bookkeeper’s or accountant’s name, address, and phone if you use one.
An estimate of monthly sales. The CDTFA uses this to assign your filing frequency.

Be realistic with the sales estimate. Lowball it and the CDTFA will reassign you to more frequent filing once your real numbers come in; overshoot and you’ll file returns more often than needed. Base the number on actual contracts, market research, or comparable businesses.

Applying Through the CDTFA Online Portal

California Revenue and Taxation Code Section 6066 authorizes electronic filing for Seller’s Permit applications, so you can do the whole thing from a computer.⁶ Go to the CDTFA’s online registration page and select the option to register a new business tax account. The system walks you through screens for the information listed above.

The portal asks about your business activities and uses your answers to determine which permits and licenses you need.⁵ Selling tangible goods queues up a Seller’s Permit. Other activities may trigger additional registrations, such as use tax or recycling fees.

Before you can submit, a terms-and-conditions screen lays out your legal obligations as a permit holder and the consequences of providing false information. Read it. When you confirm, you’re electronically signing the application, and that signature is a binding agreement with the State of California about your tax compliance.

Click submit and the system generates a confirmation number. Save it. You’ll use it to check status if the permit isn’t issued immediately. Save a copy of the summary page too; it shows everything you entered and serves as proof of filing. Many applications are approved on the spot, with the permit number issued within minutes. If the system flags a discrepancy, such as a name that doesn’t match your ID, the application goes to manual review and takes longer. Once approved, the CDTFA emails a confirmation with your permit number and instructions for printing the certificate.

What It Costs

The Seller’s Permit itself is free. No application fee, no annual renewal charge, no processing cost.⁷

The CDTFA can require a security deposit, but most first-time applicants with clean records won’t be asked for one. You’re more likely to face a deposit if you previously held a CDTFA account that was cited or revoked, or if you have a documented history of non-payment. When a deposit is required, the statutory minimum is $2,000 and the maximum is $50,000, with the actual amount typically pegged to your estimated quarterly or monthly tax liability. You can post it with cash, a personal check, a money order, a surety bond, or certain deposit accounts at banks or credit unions.⁸ The CDTFA returns the deposit after you close the account and pay off any outstanding liability.

After Approval

Display Your Permit

California law requires every Seller’s Permit to be “conspicuously displayed at the place for which issued.”² Print the certificate and post it where customers can see it. Operating without displaying your permit, or operating without one at all, is a misdemeanor.⁹

No Expiration, No Renewal

California Seller’s Permits don’t expire. Your permit stays valid as long as you remain actively engaged in business as a seller.¹⁰ There’s no renewal process. If you stop selling, the CDTFA expects you to return the permit for cancellation, and the agency can cancel it on its own once it determines you’re no longer in business.

Filing Frequency

The CDTFA assigns your sales tax return filing schedule — monthly, quarterly, quarterly with prepayments, or annually — from the taxable sales figure you provided during registration.¹¹ Higher sales volumes mean more frequent filing. If your actual sales differ significantly from your estimate, the CDTFA will reassign your frequency.

Using a Resale Certificate to Buy Inventory Tax-Free

Once you hold the permit, the practical payoff is the ability to issue resale certificates to your suppliers. A resale certificate tells the supplier not to charge sales tax on the purchase because you’re buying to resell. The supplier keeps the certificate on file, and you collect sales tax later from the end customer.¹

The form is CDTFA-230, California Resale Certificate. On it you list your Seller’s Permit number, the supplier’s name, a description of the goods, and a signed statement that you intend to resell the items in the regular course of business.¹² The certificate covers only items you actually plan to resell. Office furniture for your shop, supplies you’ll consume, or anything for personal use does not qualify.

A resale certificate is not a blanket exemption card. It applies only to merchandise heading back out the door to a customer. Divert a “resale” purchase to personal use and you owe the tax you avoided, plus penalties.

Penalties for Misusing a Resale Certificate

The CDTFA takes resale certificate abuse seriously, and the penalties make the tax savings on a personal purchase completely not worth it. Knowingly using a resale certificate to buy something you don’t intend to resell exposes you to three layers of consequences:

Back taxes. You owe the full sales tax that should have been charged at the time of purchase.
A civil penalty of 10 percent of the unpaid tax or $500, whichever is greater, for each improper purchase.¹³
Criminal charges. Intentional misuse to evade taxes is a misdemeanor.¹³

If you also fail to self-report and pay the use tax you owe on the improperly purchased items, additional penalties apply: 10 percent for negligence or 25 percent for fraud.¹⁴ The $500 floor on the civil penalty means that even a $50 purchase triggers a $500 penalty. Auditors look for patterns, such as an electronics retailer suddenly buying large quantities of building materials under a resale certificate.
