California has the highest statewide base sales tax rate in the United States, and stacked local district taxes change every quarter. Charging the wrong rate is easy and expensive. The base rate is 7.25%, and the California Department of Tax and Fee Administration (CDTFA) administers sales and use tax. Check the current figure on the CDTFA sales and use tax rates page before you charge.
This guide covers the 2026 rate, who must collect, how to register and file, and what non-compliance costs. Every figure is sourced to CDTFA or the Franchise Tax Board (FTB).
What Is the California Sales Tax Rate in 2026?
California’s statewide base sales tax rate is 7.25% in 2026, the highest state base rate in the United States, per CDTFA. Stacked local district taxes push combined rates higher, reaching 10.75% in Oakland and 11.25% in Lancaster and Palmdale. More than three-fourths of California businesses operate in an area with at least one district tax, per CDTFA.
The 7.25% base breaks down into a state portion and a 1.25% Bradley-Burns local portion.
| Component | Rate | Source |
|---|---|---|
| State rate | 6.00% | CDTFA |
| Bradley-Burns city/county operations | 1.00% | CDTFA |
| County transportation funds | 0.25% | CDTFA |
District taxes range from 0.10% to 2.00% per district and can stack, so combined rates run from 7.25% up to roughly 11.25%, per the CDTFA rate description and the CDTFA Know Your Rate page.
What Are California Sales Tax Rates by City in 2026?
Rates vary by city because district taxes stack on the 7.25% base, so verify any address before charging. Use the CDTFA address rate lookup as the canonical source. The rates below are drawn from CDTFA’s published rate list; rates change on quarterly effective dates, so re-check at each boundary.
| City / area | Combined rate | Source |
|---|---|---|
| Lancaster (Los Angeles County) | 11.250% (eff. Jul 1, 2026) | CDTFA rate list |
| Palmdale (Los Angeles County) | 11.250% (eff. Jul 1, 2026) | CDTFA rate list |
| Oakland (Alameda County) | 10.750% (eff. Oct 1, 2025) | CDTFA (notice L-989) |
| Alameda (Alameda County) | 10.750% | CDTFA rate list |
| Unincorporated Alameda County | 10.250% | CDTFA rate list |
| San Francisco | 8.625% | CDTFA rate list |
| Anaheim (Orange County) | 7.750% | CDTFA rate list |
| Statewide minimum (base) | 7.250% (since Jan 1, 2017) | CDTFA |
Why Do California Sales Tax Rates Change Every Quarter?
Voter-approved district taxes take effect and sunset on fixed dates, so CDTFA publishes new rates effective January 1, April 1, July 1, and October 1 each year. A new district tax becomes operative no sooner than the first quarter starting more than 110 days after adoption, per CDTFA. Re-check rates at each quarter boundary and never hardcode them.
CDTFA issues quarterly rate notices for each cycle, such as the notices effective April 1, July 1, and October 1, per CDTFA’s guidance on implementing district taxes. Oakland’s jump from 10.250% to 10.750% on October 1, 2025 shows the cycle in action, per CDTFA.
Who Administers California Sales Tax?
The California Department of Tax and Fee Administration (CDTFA) administers sales and use tax. The Board of Equalization (BOE) transferred its tax collection duties to CDTFA on July 1, 2017 under the Taxpayer Transparency and Fairness Act, per CDTFA. Older BOE forms and links you find online now route to CDTFA.
You register, collect, file, and pay through CDTFA online services.
Is California Sales Tax Origin-Based or Destination-Based?
California is a hybrid, modified-origin state, not purely destination-based. For in-state sellers, the state and Bradley-Burns portions source to the seller’s place of business, while district taxes source to the buyer’s location. Remote and out-of-state sellers effectively collect on a destination basis at the buyer’s full combined rate.
| Tax portion | How it sources | Where | Source |
|---|---|---|---|
| State rate (6.00%) + Bradley-Burns local (1.25%) | Origin | In-state seller’s place of business | CDTFA |
| District taxes (0.10%–2.00%) | Destination | Buyer’s location, when the seller is engaged in business in that district | CDTFA |
| Remote / out-of-state seller sales | Destination | Buyer’s full combined rate | CDTFA |
What Is Taxable and Exempt From California Sales Tax?
California taxes tangible personal property and generally does not tax services or electronically delivered digital products, per CDTFA. Clothing is fully taxable in California, with no under-$110 exemption. Standalone repair and installation labor is generally not taxable, though the parts are, and fabrication labor can be taxable.
Electronically delivered software and downloads are generally not taxable; prewritten software on a physical medium is taxable.
| Category | Treatment | Source |
|---|---|---|
| Most grocery food for home consumption | Exempt | CDTFA |
| Prescription medications | Exempt | CDTFA |
| Sales for resale (valid resale certificate) | Exempt | CDTFA |
| Interstate shipments delivered outside California | Exempt | CDTFA |
| Electronically delivered software and digital downloads | Not taxable | CDTFA |
Do I Need to Collect Sales Tax in California?
You must collect once you have nexus in California. Nexus arises immediately from physical presence, or from crossing $500,000 in sales of tangible personal property delivered into the state. Physical presence and economic activity are separate triggers, and either one alone creates a duty to register with CDTFA and collect.
What Creates Physical Nexus in California?
Physical presence triggers nexus immediately, not after 90 days. A store, office, warehouse, employee, or sales representative in California creates nexus at once, per CDTFA. Inventory stored in California also counts, including Fulfillment by Amazon (FBA) inventory in California warehouses, which quietly registers many e-commerce sellers.
What Is California’s Economic Nexus Threshold?
California’s economic nexus threshold is $500,000 in sales of tangible personal property for delivery into the state in the preceding or current calendar year, effective April 1, 2019 under AB 147, per CDTFA Wayfair guidance. California uses a dollar threshold only, with no 200-transaction test, unlike many states. Confirm your exposure with the Commenda US nexus guide.
How Does California Sales Tax Apply to Out-of-State and Marketplace Sellers?
Remote sellers over $500,000 must register with CDTFA and collect at the buyer’s combined destination rate. Marketplace facilitators are the legal retailer for sales they facilitate under California’s Marketplace Facilitator Act (AB 147), with marketplace provisions effective October 1, 2019, per CDTFA. The facilitator, not the third-party seller, is liable for tax on those facilitated sales.
Sellers should confirm the facilitator is collecting and keep documentation of that arrangement for their records. FBA inventory stored in California can still create physical nexus and a registration obligation, even when Amazon collects the tax on your marketplace sales.
When Are Interstate Shipments Exempt From California Sales Tax?
Sales shipped by the seller via common carrier or the seller’s own vehicle to a point outside California, for use outside California, are exempt, per CDTFA Publication 101. Keep documentation such as bills of lading to prove the exemption. If the buyer takes possession in California, the sale is taxable.
Customer pickup in California, then the customer shipping it out themselves, does not qualify and remains taxable. Drop shipments into California by a California drop shipper for an unregistered out-of-state retailer can make the drop shipper liable under CDTFA Regulation 1706.
What Is California Use Tax and Who Owes It?
Use tax applies at the same rate as sales tax when you buy tangible goods without paying California sales tax and then use, store, or consume them in California. There is no minimum, so any untaxed purchase is reportable. Individuals report use tax on their FTB Form 540 return or a CDTFA return; businesses report it on their CDTFA sales and use tax return.
Individuals may use the FTB’s estimated use tax lookup table for non-business purchases under $1,000, per FTB. Since Wayfair and the marketplace facilitator law, most marketplace purchases already have tax collected at checkout. Direct purchases from small out-of-state sellers below the threshold still trigger use tax.
How Do I Register for a California Seller’s Permit?
Register free with CDTFA online, and get the permit before making taxable sales, even as a wholesaler or temporary seller. Registration takes a short online session once you have your identification and business details ready. There is no fee, though CDTFA may require a security deposit in some cases.
- Gather your EIN or SSN, business entity details, and a driver’s license or state ID.
- Apply through CDTFA online services, or file form CDTFA-100 by mail.
- Receive your seller’s permit, then collect tax and file on your assigned frequency.
- Keep records for at least four years.
Permits do not expire but must be updated on ownership or structure changes. For a deeper walkthrough, read Commenda’s guide on how to register, verify, and use a sales tax permit.
How Do Resale and Exemption Certificates Work in California?
Buyers purchasing for resale give the seller a completed resale certificate (CDTFA-230 General Resale Certificate), and the seller keeps it on file to document the exempt sale. The seller’s duty is to accept the certificate in good faith and retain it, not to police the buyer’s use. Certificate misuse by the buyer is a misdemeanor, per CDTFA.
A valid certificate needs the buyer’s seller’s permit number, a description of the property, a statement that it is purchased for resale, a signature, and a date. Other exempt purchasers include government entities, qualifying 501(c)(3) nonprofits, and certain educational institutions.
How Do I File a California Sales Tax Return?
File online through CDTFA online services using return CDTFA-401-A, by the due date for your assigned frequency, and pay when you file. CDTFA sets your frequency from your average monthly tax liability. Even a period with zero sales requires a zero return.
| Frequency | Average monthly tax liability | Due date | Source |
|---|---|---|---|
| Monthly | More than $1,200 | Last day of the following month | CDTFA |
| Quarterly | $101 to $1,200 | Last day of the month after the quarter | CDTFA |
| Semiannual | $51 to $100 | Last day of the month after the period | CDTFA |
| Annual | $50 or less | Last day of the month after the year | CDTFA |
Payment methods: electronic funds transfer (EFT) via the CDTFA portal, card through a third-party processor with fees, or check by mail. Track deadlines with the Commenda compliance calendar.
Do I Need to Make Sales Tax Prepayments?
CDTFA requires prepayments from sellers whose taxable sales average $17,000 or more per month, per CDTFA prepayment guidance. Those sellers make two prepayments plus a quarterly return each quarter. The prepayment threshold is set by CDTFA, so confirm your current status in your CDTFA online services account.
What Are the Penalties for Late California Sales Tax Filing?
CDTFA charges a 10% penalty for late filing or late payment, plus interest from the due date until the tax is paid, per CDTFA. Larger penalties apply when a seller collects tax and fails to remit it or operates without a permit.
| Situation | Penalty | Source |
|---|---|---|
| Late filing or late payment | 10% of tax due, plus interest | CDTFA |
| Failure to remit tax already collected | 40% (exception where average monthly tax is under $1,000) | CDTFA |
| Operating without a seller’s permit | 50% of tax due | CDTFA |
| Misuse of a resale or exemption certificate | $1,000–$5,000 fine, up to one year imprisonment (misdemeanor) | CDTFA |
| Unpaid tax | Interest at CDTFA’s published rate from the due date | CDTFA |
When tax stays unpaid, CDTFA can levy bank accounts, encumber property, and seize assets. Intentional evasion can bring criminal charges.
How Long Must You Keep California Sales Tax Records?
Keep California sales tax records for at least four years, and longer if you are under audit or did not file returns, per CDTFA. Records means sales invoices, purchase invoices, exemption and resale certificates, ledgers, point-of-sale (POS) reports, and filed returns.
If records are missing, CDTFA auditors can estimate liability from available data, which typically works against the business.
How Should I Prepare for a CDTFA Sales Tax Audit?
Auditors verify gross receipts, deductions, local tax allocation, and rate application against your records, so organized four-year records and valid certificates are the core defense. Clean books and correct taxability treatment resolve most audit questions before they escalate.
- Keep organized records and reconcile them to filed returns.
- Apply correct taxability treatment to goods, services, and districts.
- Bring professional representation to the exit interview.
- Appeal findings with supporting documentation if you disagree.
