California calls it a seller’s permit, not a sales tax permit. The California Department of Tax and Fee Administration (CDTFA) issues it for free, you register online, and most straightforward applications are approved the same day. Complex cases can take days to a few weeks.
You need one if you have any physical presence in California or if remote sales cross the state threshold. Register through CDTFA’s Online Services registration portal, and you can start collecting tax the moment you submit.

What Is a California Seller’s Permit?
A California seller’s permit is the state license that authorizes a business to collect and remit sales and use tax on taxable retail sales. It also lets you issue resale certificates to suppliers, per CDTFA Publication 107. “Seller’s permit” is the official CDTFA term for what most people call a sales tax permit.
The CDTFA administers this permit. The agency began operations on July 1, 2017, taking over sales and use tax administration from the State Board of Equalization (BOE) under the Taxpayer Transparency and Fairness Act of 2017, per California Government Operations Agency. Older third-party guides that still name the BOE are out of date.
Do I Need a Sales Tax Permit in California?
Yes if you have any physical presence in California, or if you are a remote seller with more than $500,000 in tangible personal property delivered into California in the current or prior calendar year. Physical presence requires registration regardless of sales volume. The remote-seller test looks only at sales dollars.
What creates physical nexus?
Physical nexus comes from any real presence in the state. That includes stores, offices, employees, representatives, and inventory held in California warehouses, including Fulfillment by Amazon (FBA) stock. Any one of these requires registration on day one, regardless of revenue. A single remote employee or a batch of FBA inventory is enough.
What is California’s economic nexus threshold?
California’s economic nexus threshold is $500,000 in combined sales of tangible personal property delivered into the state, with no separate transaction count. Assembly Bill 147 (AB 147) set this figure, operative April 1, 2019, after the U.S. Supreme Court decided South Dakota v. Wayfair on June 21, 2018. All channels, including marketplace sales, count toward the threshold.
| Trigger | Who it applies to | Source |
|---|---|---|
| Any physical presence (store, office, employee, FBA inventory) | All sellers, regardless of volume | CDTFA |
| $500,000 in TPP sales delivered into California (current or prior year) | Remote and out-of-state sellers | CDTFA Wayfair page; AB 147 |
| No 200-transaction test | All remote sellers | CDTFA Wayfair page |
Unlike most states that use a “$100,000 or 200 transactions” rule, California dropped the transaction count. Check your exposure with Commenda’s US nexus exposure guide and the California sales tax guide.
How Do You Register for a California Sales Tax Permit? (Step-by-Step)
Register through CDTFA Online Services under “Register a New Business,” for free. The system saves your progress at each step and identifies every permit your activities require. You can begin collecting tax as soon as you submit, before the permit arrives.
- Confirm your obligation. Verify you have physical nexus or over $500,000 in California sales.
- Gather your information. Have your legal name, EIN, NAICS code, and estimated sales ready (full checklist below).
- Create your CDTFA account. Set up login credentials in Online Services.
- Complete the application. Enter business details and indicate you are applying for a seller’s permit.
- Submit. CDTFA assigns your filing frequency from your estimated liability.
- Receive and display your permit. Post it at your business location if you have one.
Note: CDTFA deletes partially completed applications after 30 days, per the CDTFA registration page, so finish in one sitting where you can.
What Information Do You Need to Apply? (Checklist)
You need your legal and business identity details, tax identification numbers, product and sales estimates, and responsible-party information. Have everything ready before you start so the application does not stall.
| Item | Who needs it | Source |
|---|---|---|
| Legal business name and DBA (doing business as) | All applicants | CDTFA registration page |
| Business entity type | All applicants | CDTFA registration page |
| EIN (Employer Identification Number) or SSN (Social Security Number) for sole proprietors | All applicants | CDTFA registration page |

How Much Does a California Sales Tax Permit Cost?
Registration is free. CDTFA charges no fee for a seller’s permit, per CDTFA Publication 107. CDTFA notes that some accounts “may require a fee or deposit,” and a security deposit, when required, is set at CDTFA’s discretion and is refundable when you close the account and pay any tax due.
| Deposit rule | Detail | Source |
|---|---|---|
| Permit fee | $0 | CDTFA Publication 107 |
| When a deposit applies | Only for applicants with a poor payment history or high compliance risk | CDTFA Compliance Policy Manual (CPM-04) |
| Minimum deposit | $2,000 (waived if the computed amount is less) | CDTFA CPM-04 |
| Maximum deposit | $50,000, or 2x quarterly / 3x monthly liability, whichever is less | Revenue & Taxation Code §6701 |
| Time to post | About 30 days after a CDTFA-598 notice; the permit is not delayed | CDTFA CPM-04 |
Most applicants are never asked for a deposit. The requirement follows the individual, capped cumulatively at $50,000 per person, per CDTFA CPM-04.
How Long Does It Take to Get a California Sales Tax Permit?
Straightforward online applications are often approved the same day. CDTFA states it “may be able to issue your permit the same day” you apply, per CDTFA Publication 107. Applications flagged for review, out-of-state entities, or accounts that require a deposit determination can take days to a few weeks. You collect tax from submission, not from permit arrival.
Do Amazon and Marketplace Sellers Need a California Seller’s Permit?
It depends on your inventory and channels. Under California’s Marketplace Facilitator Act, effective October 1, 2019 (CDTFA), Amazon, eBay, Etsy, and Walmart collect and remit tax on their platform sales for you. You may still need your own seller’s permit if you hold FBA inventory in California or sell through other channels.
- Marketplace-only, no California inventory: the facilitator handles the tax; you generally do not need your own permit.
- FBA inventory stored in California: you have physical nexus and must register for a seller’s permit.
- Mixed channels (your own site plus a marketplace): register and collect on your direct sales; the facilitator covers its platform sales.
The facilitator’s collection obligation is separate from your own permit trigger. Holding inventory in a California fulfillment center is the trigger most sellers miss.
How Do Out-of-State and Foreign Companies Register?
The process is identical: the same CDTFA online portal and the same $500,000 threshold, with no California address required. Out-of-state U.S. sellers register directly online and list their home-state address. The registration itself is the same one an in-state retailer completes.
Non-U.S. companies can register too, but they need an EIN. You can obtain one from the IRS using Form SS-4 without a U.S. SSN. A CDTFA seller’s permit is separate from California Secretary of State foreign qualification. One does not substitute for the other, and a foreign qualification alone does not create sales tax nexus.
What Are the California Seller’s Permit Requirements for an LLC?
A limited liability company (LLC) registers the same way and needs its EIN, formation details, and responsible member or manager information. New owners often conflate three separate obligations, so keep them distinct.
| Obligation | Who handles it | What it costs | Source |
|---|---|---|---|
| Form the LLC | California Secretary of State | State filing fee | California Secretary of State |
| Seller’s permit | CDTFA | $0 | CDTFA Publication 107 |
| Annual franchise tax | Franchise Tax Board (FTB) | $800 minimum per year | California Franchise Tax Board |
The seller’s permit is only the sales tax piece. It does not replace forming the entity or paying the franchise tax.
What Is the California Sales Tax Rate?
The statewide base rate is 7.25%, the highest state base rate in the U.S. Per CDTFA, the rate has three parts: the state rate, the local rate, and district taxes. Combined rates exceed 10% in some localities because multiple voter-approved district taxes can stack.
| Component | Rate | Source |
|---|---|---|
| State rate | 6.00% | CDTFA rate description |
| Local rate (county and city) | 1.25% | CDTFA rate description |
| Statewide base total | 7.25% | CDTFA rate description |
| District taxes (add-on) | 0.10%–2.00% | CDTFA rate description |
District taxes are voter-approved local add-ons, and more than one can apply in a single location, per CDTFA Publication 105. Rates change by address, so look up an exact combined rate with Commenda’s sales tax calculator.
What Happens After You Register?
CDTFA assigns your filing frequency (monthly, quarterly, or annual) from your estimated liability, and you file every period, including zero-sales periods. Missing a return brings penalties and interest even when you owe nothing. CDTFA can reassess your frequency as actual sales change.
When are California sales tax returns due?
Returns are due at the end of the month after each reporting period closes, per CDTFA filing-date schedules. Quarterly filers report four times a year; monthly and annual filers follow the same month-end rule.
| Filing basis | Reporting period | Due date | Source |
|---|---|---|---|
| Quarterly | Jan–Mar / Apr–Jun / Jul–Sep / Oct–Dec | Apr 30 / Jul 31 / Oct 31 / Jan 31 | CDTFA |
| Monthly | Each calendar month | Last day of the following month | CDTFA |
| Annual | Jan–Dec | Jan 31 | CDTFA |
How do you manage your CDTFA online account?
You receive login credentials, and the CDTFA portal is your hub for everything after registration. From your account you file returns, make payments, view filing history, update business and responsible-party details, and access notices and your permit. Keep your contact and address details current to avoid missed deadlines.
What records and bookkeeping do you need?
California requires you to keep sales records, invoices, and exemption certificates for at least four years, per CDTFA. Zero returns are mandatory, and you must update CDTFA when business details change. Maintain a dedicated bookkeeping process, and consider sales tax automation software to track rates and streamline filings.
Do Sellers Have to Collect California Use Tax?
Yes, when sales tax was not charged. Use tax applies to goods stored, used, or consumed in California, including mail-order, phone, and internet purchases shipped from another state, per the CDTFA Sales & Use Tax page. Retailers engaged in business in California must collect it, and the same CDTFA registration covers both sales and use tax.
When Should You Close Your California Seller’s Permit?
Close your permit when you stop operating, sell the business, change ownership, or stop taxable activity. CDTFA requires this, per CDTFA Publication 74. Failing to notify CDTFA can leave you liable as a predecessor for a successor’s taxes, penalties, and interest, so close the account promptly and file your final return.
