To get a Seller’s Permit in California, apply online through the California Department of Tax and Fee Administration (CDTFA) registration portal. The permit is free, and most applicants can complete the process in a single sitting if they have their business, personal, and financial information ready. Any business that sells or leases physical goods in California needs one before making its first sale, and selling without a valid permit is a misdemeanor punishable by a fine up to $5,000 and up to a year in jail.1California Legislative Information. California Code RTC 6071
Before You Apply: What to Gather
The online system moves quickly once you start, and missing information will stall you. Pull everything together first. The CDTFA asks for:2California Department of Tax and Fee Administration. Get a Seller’s Permit
- Your legal business name, any fictitious business name (DBA), physical business address, and entity type (sole proprietorship, partnership, LLC, or corporation)
- Social Security number (corporate officers excluded), date of birth, and a driver’s license, state ID, passport, or military ID
- The name and location of your bank, estimated average monthly total sales, and estimated average monthly taxable sales
- Names and addresses of your major suppliers, name and address of your bookkeeper or accountant, and personal references
- If you bought an existing business, the previous owner’s permit information
Partners, corporate officers, and LLC members or managers each need to provide their own identifying information. The sales estimates matter because the CDTFA uses them to set your filing frequency, so give them real thought rather than a rushed guess.
How to Apply Online
Go to the CDTFA website and choose the option to register for a new permit, license, or account. If you don’t already have a CDTFA Online Services profile, the system will walk you through creating one.
The application is a guided series of questions covering your business structure, identification numbers, sales estimates, and supplier details. The CDTFA handles more than just sales tax, so the system uses your answers to flag any other tax registrations you might also need. Review your answers and submit. There is no filing fee.3California Department of Tax and Fee Administration. Obtaining a Seller’s Permit
You’ll usually see a confirmation number right away. Once the CDTFA approves the application, print the official permit and display it at your place of business where customers can see it.
Do You Actually Need a Permit?
You need one if you’re “engaged in business” in California and sell or lease tangible personal property, meaning any physical item that can be seen, weighed, measured, or touched. That covers retailers, wholesalers, manufacturers who sell directly, and anyone selling at craft fairs, flea markets, or pop-up shops. It also covers service providers whose end product is a physical item, like a custom furniture builder or jewelry maker.
Businesses that provide only non-taxable services, such as consulting, accounting, or tutoring, and never sell or lease physical goods generally don’t need a permit. Truly isolated sales may also fall outside the requirement, but the line between “occasional” and “regular” is thinner than most people think. If you’re selling often enough to wonder, you probably need one.
Marketplace-Only Sellers
If you sell exclusively through a marketplace facilitator like Amazon, Etsy, or eBay, you typically don’t need your own permit because the platform collects and remits sales tax for you. The moment you also sell directly to California customers through your own website, at a fair, or any channel not facilitated by a registered marketplace, you have to register with the CDTFA and hold your own permit.4California Department of Tax and Fee Administration. Tax Guide for Marketplace Facilitator Act
Out-of-State Sellers
If your business is located outside California but you sell more than $500,000 in taxable goods delivered to California customers in the current or preceding calendar year, you must register with the CDTFA and collect California use tax, even without a physical presence in the state.5California Department of Tax and Fee Administration.

Temporary Sellers
If you’re selling at a single location for fewer than 90 days, such as a fireworks stand, Christmas tree lot, or seasonal festival, you can apply for a temporary Seller’s Permit instead of a standard one. The temporary permit covers only that specific selling period.6California Department of Tax and Fee Administration. Applying for a Seller’s Permit
Multiple Locations
California requires a separate permit for each place of business where you negotiate sales with customers. A branch office where staff take orders needs its own permit, even if no inventory is stored there. If you run two different operations on the same physical property, like a gas station and a restaurant on the same lot, one permit covers both. Warehouses used only for storage don’t need their own permits, as long as they’re connected to a location that already has one. The exception: a warehouse that fulfills or ships retail orders negotiated from out of state does need its own permit.7California Department of Tax and Fee Administration. Regulation 1699
Will You Owe a Security Deposit?
Most new applicants won’t. The CDTFA generally reserves deposits for situations required by law, applicants with a history of unpaid taxes, or elevated compliance risk. When a deposit is required, it falls between $2,000 and $50,000; amounts below $2,000 are waived entirely. For quarterly filers, the typical calculation is twice your estimated average quarterly tax liability. If you do pay one, you can get it back after three years of clean compliance, meaning all returns filed on time and all taxes paid in full.8California Department of Tax and Fee Administration. Compliance Manual Chapter 4
What the Permit Lets You Do
A Seller’s Permit does two things at once. It authorizes you to collect sales tax from customers and remit it to the state, and it lets you buy inventory tax-free from suppliers by issuing a resale certificate.
Resale Certificates
When you buy goods you intend to resell, you give your supplier a resale certificate so you aren’t charged sales tax at purchase. The certificate can take any form, including the CDTFA’s standard CDTFA-230, as long as it includes your name and address, your Seller’s Permit number, a description of the goods, a statement that the goods are being purchased for resale, the date, and your signature or that of an authorized representative.9Taxes.ca.gov. Resale Certificates
Misusing a resale certificate, meaning buying something tax-free that you actually intend to keep, is a misdemeanor. You’ll also owe the tax that should have been paid plus a penalty of 10 percent of that tax or $500, whichever is more.10California Department of Tax and Fee Administration. California Resale Certificate – CDTFA-230
Collecting and Filing Sales Tax
Once your permit is active, you have to collect the correct sales tax on every taxable sale. California’s base statewide rate is 7.25%, but local city, county, and district taxes push the combined rate higher depending on where the sale takes place. Some cities currently have combined rates as high as 10.75%.11California Department of Tax and Fee Administration. California City and County Sales and Use Tax Rates The CDTFA’s online rate lookup tool lets you find the exact rate for any address.12California Department of Tax and Fee Administration. Know Your Sales and Use Tax Rate
The CDTFA assigns your filing frequency, monthly, quarterly, quarterly with prepayments, yearly, or fiscal yearly, based on the sales volume you estimated during registration. You have to file a return by the deadline even if you had zero sales during that period.13California Department of Tax and Fee Administration. Filing Dates for Sales and Use Tax Returns
Penalties for Selling Without a Permit
Selling in California without a valid Seller’s Permit is a misdemeanor. A court can impose a fine up to $5,000, jail time up to one year, or both. Corporate officers are individually liable for the offense, not just the business entity.1California Legislative Information. California Code RTC 6071
For permit holders who file or pay late, the CDTFA applies a 10 percent penalty on the tax due. Filing late and paying late won’t double the penalty; the combined penalty caps at 10 percent of the tax owed for that reporting period. Interest also accrues monthly on any unpaid amount.14California Department of Tax and Fee Administration. Interest, Penalties, and Collection Cost Recovery Fee
Given that the permit itself costs nothing and the application takes less than an hour with the right information in front of you, registering before your first sale is straightforward. Open the CDTFA registration portal, work through the questions, and keep the confirmation for your records.
