If you’re planning to sell goods or taxable services in California, securing a California sales tax permit is a legal must. Also known as a seller’s permit, this account allows businesses to collect and remit sales tax to the state. Whether you’re launching an online store, opening a storefront, or selling temporarily at events, the California Department of Tax and Fee Administration (CDTFA) requires registration before your first sale. Navigating the process can be confusing—but that’s where HOST comes in.
As your dedicated sales tax compliance partner, Hands Off Sales Tax (HOST) simplifies permit registration, filings, and multi-state management so you can stay focused on growth.
Who Needs a California Sales Tax Permit?
In California, a sales tax permit—technically called a seller’s permit—is required for any individual or business “engaged in business” within the state. But what exactly qualifies as being engaged in business?
Physical or Economic Nexus Triggers
You’re considered engaged in business in California if you:
- Have a physical presence (such as an office, warehouse, or employee) in the state, or
- Exceed $500,000 in annual sales of tangible personal property delivered into California, even without physical presence. This threshold was introduced under AB 147, following the Supreme Court’s Wayfair decision.
This includes out-of-state and online sellers once they cross that economic nexus limit.
Temporary Sellers Must Register Too
Even if you’re selling at a craft fair, flea market, or temporary event lasting fewer than 90 days, you still need to register with the CDTFA. In these cases, you must apply for a temporary seller’s permit—a special version of the standard seller’s permit meant for one-time or short-term activities.
If you hold multiple events at different locations, separate permits or location IDs may be required.
Whether your operations are year-round or seasonal, registering for the appropriate permit is essential to staying compliant in California.
Preparing for Registration: What You’ll Need
Before you begin your California sales tax permit application, gather the necessary documentation to avoid delays. The California Department of Tax and Fee Administration (CDTFA) requires specific information to verify your business identity, operations, and expected tax liability.
Required Information & Documents
You’ll need to provide the following:
- Personal Identification: Social Security Number (SSN), California driver’s license or state ID
- Federal Tax ID: Employer Identification Number (EIN) from the IRS
- Business Details:
- Business name and structure
- Start date and business location
- NAICS code (industry classification)
- Owner Information: Names, addresses, and contact details of owners, partners, or officers
- Banking Information: Routing and account numbers (for electronic payments/refunds)
- Estimated Sales Volume: Monthly or quarterly revenue expectations
Security Deposit Requirements
In some cases, especially if your business has a history of unpaid taxes or liabilities, the CDTFA may request a security deposit. This can be in the form of cash, a bond, or other instruments and is used to cover any potential unpaid tax liabilities source.
Having these materials ready makes the registration process smoother and helps avoid costly rejections or processing delays.

Temporary Sellers & Event-Based Registration
If you plan to sell goods in California for a short duration—such as at a craft fair, trade show, or festival—you may qualify for a temporary California sales tax permit instead of a full seller’s permit.
Who Qualifies
According to the California Department of Tax and Fee Administration (CDTFA), temporary permits are available for:
- Selling activities lasting 90 days or less
- Sales at a single location or specific event
- Sellers not regularly engaged in business in California
Filing and Compliance
Even with a temporary permit, you’re required to:
- Collect and report sales tax for taxable transactions
- File returns for the applicable filing period (usually one-time filing)
- Keep records of sales, exemptions, and purchases
If you plan to continue selling beyond the temporary period or expand to multiple events/locations, you’ll need to upgrade to a regular seller’s permit via CDTFA’s online portal.
What Happens Next: Post-Registration Process
Once you’ve completed your CDTFA registration for a California sales tax permit, a few important steps follow to activate and maintain compliance.
Receiving Your Permit
- After submission, your seller’s permit is available immediately in your CDTFA online dashboard.
- A physical copy (Form CDTFA-AAA) will be mailed to your business address within 7–10 business days.
You can log in anytime here: CDTFA Online Services Portal
Filing Frequency Assignment
The CDTFA assigns your sales tax filing frequency based on your projected sales volume:
- Quarterly – most common for small to mid-sized businesses
- Monthly or prepayment – for higher-volume sellers
- Annual – typically for sellers under $100/month in tax liability
Filing Deadlines and Penalties
Sales tax returns are due on the last day of the month following your reporting period. Failing to file—even if you made no sales—can result in penalties, interest, and account suspension. CDTFA expects zero returns when no tax is due.
Ongoing Compliance Requirements
Registering for a California sales tax permit is just the first step. Staying compliant means keeping your permit active, your records updated, and your filings on time.
Zero-Return Filing
Even if you make no taxable sales during a reporting period, the California Department of Tax and Fee Administration (CDTFA) still requires a “zero return” to be filed. Failure to do so can result in late penalties and interest charges.
Keeping Business Information Current
If your business experiences any of the following, update your CDTFA account promptly:
- Business address changes
- Change in ownership, officers, or business structure
- Updates to NAICS code or sales activity
You can make these changes easily via your CDTFA Online Services account:
Closing Your Seller’s Permit
If you’re permanently ceasing business operations, you must close your permit to avoid ongoing filing obligations. This can be done online through the CDTFA portal or by submitting a Request for Closure.
Maintaining accurate records and meeting these compliance responsibilities protects you from unnecessary penalties and keeps your permit in good standing.
