Foreign sellers may need to collect and remit California sales tax when they are engaged in business in California. California’s rules apply to taxable sales of tangible personal property delivered to California, and the obligation can arise from physical activities in the state or from California’s remote-seller economic nexus rule. A foreign seller’s country of residence does not, by itself, remove the obligation.
California is especially important to manage carefully because it is not a home-rule state: local jurisdictions do not administer their own separate sales-tax systems. The California Department of Tax and Fee Administration (CDTFA) administers the state system, including registration through its online services portal, seller’s permits, returns, payments, and district-tax reporting. California applies a statewide base rate plus applicable district taxes, so the correct rate generally depends on the customer’s delivery address, potentially down to the street level.
California sales tax obligations for foreign sellers
A foreign seller generally must register with the CDTFA and collect California sales tax when it is engaged in business in California and makes taxable retail sales of tangible personal property delivered to California. A seller’s obligation is determined by its activities and sales, not by whether the business is incorporated in the United States. Sales that are genuinely exempt, sales for resale supported by the required documentation, and sales delivered outside California must be treated separately from taxable California retail sales.
California’s remote-seller rule can apply even when the seller has no California office or employee. The CDTFA states that a retailer is generally required to register when its total combined sales of tangible personal property for delivery in California, by the retailer and related persons, exceed $500,000 during the preceding or current calendar year. The exact application depends on the seller’s structure, related parties, product, and delivery arrangements, so foreign sellers should confirm their position with the CDTFA or have it reviewed before relying on an exemption from registration.
When a foreign seller has California sales tax nexus
California nexus may arise through physical presence, economic activity, or both. Physical nexus can exist when the seller has a place of business, inventory, representatives, agents, or other people operating in California for purposes connected with selling, delivering, installing, assembling, or taking orders for tangible merchandise. Inventory stored in California, including inventory held for fulfillment, is a particularly important fact to investigate.
The CDTFA also identifies activities involving leased tangible merchandise situated in California and certain vehicle, vessel, and aircraft transactions as registration triggers. A marketplace, logistics provider, contractor, or other third party can create facts that require review; the answer depends on what the third party actually does, where goods are located, and whether it acts under the seller’s authority. Keep contracts, inventory reports, shipping records, and service descriptions available for the nexus analysis.
California’s economic nexus threshold for overseas businesses
For a remote seller, California’s principal economic nexus threshold is more than $500,000 in total combined sales of tangible personal property for delivery in California during the preceding or current calendar year. The CDTFA describes the test as including sales by the seller and all persons related to the seller. This is a sales threshold, not a profit threshold, and it concerns deliveries into California.
Foreign sellers should not assume that falling below the threshold resolves every California obligation. Physical presence can create nexus independently, and special rules can apply to particular transactions or structures. The calculation should include the relevant seller and related-person sales and should distinguish taxable sales, exempt sales, and sales of property outside the rule where appropriate. If the facts are close to the threshold, confirm the current CDTFA position before deciding not to register.
How to register for a California seller’s permit from another country
A foreign business can begin registration through the CDTFA online services portal. On the CDTFA website, select the online registration option for a permit, license, or account and choose the option to register a new business activity. The application requires business and ownership information, business addresses, contact details, sales information, and other identifying details. Use the legal name and ownership information that match the business’s official records.
Registration is not the same as filing compliance. After receiving the account information, the seller must establish how it will calculate tax, maintain sales records, retain exemption and resale documentation, file returns, and pay amounts due. The CDTFA assigns a filing frequency based on reported or anticipated sales-tax activity. If the online application or identification requirements do not fit a foreign business, contact the CDTFA directly rather than submitting incomplete or inaccurate information.
Which products and services are taxable in California
California sales tax generally applies to retail sales of tangible personal property. That category commonly includes physical goods sold to California customers, but taxability can change based on the product, the customer, the transaction, and an applicable exemption. Do not assume that a product is taxable or exempt solely because it is sold online or shipped from another country.
Many services are not taxable merely because they are services, while services that produce, fabricate, or otherwise involve taxable tangible personal property can require a different analysis. Specific exemptions may apply to qualifying food, prescription medicines, certain farm property, and other transactions, but an exemption must satisfy its conditions. For exempt California sales, collect and retain the applicable resale certificate, exemption certificate, or other supporting evidence and record the reason for the deduction on the return. The CDTFA’s product-specific guidance should control where classification is uncertain.
Are shipping and delivery charges taxable in California?
California treatment depends on the delivery arrangement and how charges appear on the invoice. Delivery charges may be excluded when they are separately stated on the invoice or other bill of sale and the stated conditions are satisfied. If delivery charges are not separately stated, they are taxable. Handling charges are generally taxable.
Charges can also be taxable when the seller uses its own vehicle, even if the delivery charge is separately stated. A foreign seller should therefore separate product price, shipping, handling, and other charges in its checkout and invoices, then review the actual carrier and delivery arrangement. The safest treatment for a mixed or unusual arrangement is to confirm it with the CDTFA before applying an exemption.
How to calculate California state, local, and district sales tax
California’s statewide base sales and use tax rate is 7.25%. Applicable district taxes are added to that base rate, and district rates vary by location. The CDTFA states that district tax rates range from 0.10% to 2.00%, and more than one district tax may apply in a particular area. The total rate is therefore not a single California-wide checkout rate.
For shipped orders, determine the applicable rate using the delivery location and the seller’s California registration and collection obligations. Use the CDTFA rate lookup by address and retain the address, rate used, transaction date, taxable amount, and tax calculation in the order records. Because district boundaries can follow local jurisdictions and rates can change, do not hard-code one rate for all California customers or rely on a city name without verifying the address.
Collect tax correctly and document exempt California sales
Once registered, collect the tax that applies to each taxable transaction and present it clearly on the customer’s invoice or order record. Your records should show the purchaser, delivery address, transaction date, items sold, taxable and nontaxable amounts, shipping and handling treatment, tax rate, district allocation where relevant, and tax collected. These records support accurate returns and help explain how the seller reached each result.
Do not treat a customer’s statement that an order is for a business as sufficient proof of resale. Obtain and retain a valid resale certificate or other documentation required for the particular exemption. For sales delivered outside California, preserve shipping and delivery evidence supporting the interstate or foreign-commerce treatment. Missing documentation can make a claimed deduction difficult to defend, so build the evidence requirement into order processing rather than trying to reconstruct it later.
File California sales tax returns and pay on time
The CDTFA assigns a filing frequency based on reported sales-tax activity or anticipated taxable sales. Possible frequencies include quarterly prepay, quarterly, monthly, fiscal yearly, and yearly. The frequency is not chosen solely because the seller is foreign; it is assigned to the account and can depend on the seller’s activity. Confirm the assigned frequency and due dates in the CDTFA account and current filing schedule.
Returns must report the required sales, deductions, taxable amounts, tax collected, and applicable district taxes. District taxes may require reporting on the appropriate schedule. File even when the period has no taxable sales if the account instructions require a return. Payment should be made through the CDTFA online services portal or another accepted method by the stated deadline; when a due date falls on a weekend or state holiday, the CDTFA states that the due date is extended to the next business day.
Resolve past-due California sales tax obligations
If a foreign seller missed registration, failed to collect tax, filed late, or underreported California sales, act promptly. First identify the periods involved, California deliveries, inventory and representative activity, tax collected, exemptions claimed, and amounts already paid. Reconcile sales records to payment processor, marketplace, warehouse, and shipping data before preparing corrective filings.
Contact the CDTFA to discuss registration, delinquent returns, amendments, notices, payment arrangements, penalties, and interest. Do not ignore notices or assume that closing an online store closes the tax account. A voluntary disclosure or other relief process may be available in some circumstances, but eligibility and terms depend on the facts and current CDTFA procedures. Sales Tax Compliance USA can help organize the records, assess the exposure, prepare filings, and coordinate the next steps with the CDTFA; the exact position depends on your circumstances and should be confirmed with the CDTFA or reviewed by a qualified adviser.

Frequently asked questions
Do foreign sellers need to collect California sales tax?
Yes, when the seller is engaged in business in California and makes taxable retail sales delivered to California. Nexus may result from physical presence or from California’s economic nexus rule. A foreign seller without nexus generally should not collect California sales tax merely because the customer is located there, but the exact facts should be confirmed with the CDTFA.
What is the California economic nexus threshold for foreign sellers?
The CDTFA identifies a threshold of more than $500,000 in total combined sales of tangible personal property for delivery in California during the preceding or current calendar year. The calculation includes sales by the seller and related persons. Physical presence can create an obligation independently of this threshold.
What activities create physical nexus in California?
Activities can include maintaining a California place of business or inventory, and having people operating in California under the seller’s authority to sell, deliver, install, assemble, or take orders for tangible merchandise. Leasing tangible merchandise situated in California and certain vehicle, vessel, or aircraft transactions can also matter. Review the actual activities and contracts rather than relying on a generic checklist.
How do I register for a California seller’s permit from another country?
Use the CDTFA online services portal and select the online registration path for a permit, license, or account, followed by registration of a new business activity. Prepare accurate legal, ownership, address, contact, and sales information. If the portal does not accommodate your circumstances, contact the CDTFA for instructions rather than guessing at the application.
What California sales tax rate should I charge customers?
Start with California’s 7.25% statewide base rate and add applicable district taxes. The total rate depends on the delivery address, and more than one district tax can apply. Use the CDTFA address-based rate lookup for the current rate and retain the calculation with the order records.
Are shipping and delivery charges taxable in California?
Separately stated delivery charges may be excluded when the CDTFA’s conditions are met. Unseparated delivery charges are taxable, handling charges are generally taxable, and delivery charges can be taxable when the seller uses its own vehicle. Review the exact invoice and delivery arrangement before applying an exemption.
Which products and services are taxable in California?
Retail sales of tangible personal property are generally taxable unless an exemption applies. Services are not automatically taxable merely because they are services, but a service involving the production or fabrication of tangible personal property can require different treatment. Product-specific exemptions and documentation requirements should be checked with the CDTFA.
How often do foreign sellers file California sales tax returns?
The CDTFA assigns the account a filing frequency based on reported or anticipated sales-tax activity. Frequencies can include quarterly prepay, quarterly, monthly, fiscal yearly, and yearly. Confirm the assigned frequency and current due dates in the CDTFA account; foreign status does not determine the filing frequency by itself.
