California’s treatment of SaaS and digital products is changing. Under the current rules described by the California Department of Tax and Fee Administration (CDTFA), electronically delivered software and other digital products are generally not subject to sales or use tax when the customer receives no tangible personal property. A new rule will bring many digital products—including prewritten software accessed remotely—within the tax base, with a limited $5 million, per-customer threshold that can shift responsibility to the purchaser. The details depend on what you sell, how it is delivered, and the customer’s circumstances.
California’s statewide rate is 7.25%, but district taxes can raise the total rate. For taxable sales, the applicable rate depends on the delivery location, so use the customer’s address and CDTFA’s address lookup rather than assuming one statewide rate. This guide explains the current and upcoming treatment, registration, sourcing, filing, and records. Because the digital-products rules are changing, confirm the current requirements with CDTFA or ask Sales Tax Compliance USA to review your products and sales.
When California sales tax applies to SaaS and digital products
Under current California rules, sales tax generally applies to retail sales of tangible personal property. CDTFA says charges for computer programs or other digital products transferred electronically are not subject to sales or use tax when the purchaser receives no tangible personal property, such as storage media, in the transaction. That generally covers software downloads and digital content delivered online. If a transaction includes a physical copy or storage medium, the physical component can change the tax result.
California’s rules are changing to include digital products in the tax base. CDTFA describes a digital product as prewritten computer software transferred on tangible storage media, electronically, or accessed remotely. The new treatment includes prewritten SaaS, subject to statutory exceptions and the threshold described below. Do not assume that a product’s online-only delivery keeps it exempt under the new rules; review the product and transaction under the current CDTFA guidance.
Which software and digital products are taxable?
Under the new digital-products rules, prewritten software can be taxable whether it is delivered on physical media, downloaded, or accessed remotely. Prewritten software means software held or existing for general or repeated sale or lease; CDTFA notes that software initially developed on a custom basis can still meet that definition if it is later held for general or repeated sale or lease. SaaS providers should therefore assess the underlying product and the applicable threshold, not rely only on the fact that customers log in through a browser.
Digital products can include software, digital books, mobile applications, and digital images. Their treatment depends on the current rule, the product’s characteristics, the delivery method, and any applicable exception. A bundle that includes a digital product and a service, physical item, or other component may require separate analysis. Keep a clear description of each product and how the customer receives it.
What software, services, and digital goods are exempt?
CDTFA identifies several exceptions under the new digital-products law, including digital products representing a service other than SaaS, custom computer software, digital products transferred with reproduction and distribution rights, and digital products purchased solely for use outside California. These exceptions are fact-specific. In particular, a product described commercially as “custom” may not qualify if it is held or exists for general or repeated sale or lease.
Under the current treatment, electronically transferred software and digital products are generally not taxable when the purchaser receives no tangible personal property. Charges for services are generally not taxable unless the services are part of a sale of tangible personal property. Physical copies, storage media, and mixed transactions can produce a different result. Document the facts supporting an exemption and confirm the current rule with CDTFA when a product does not fit neatly into a category.
How the $5 million threshold affects tax collection
The threshold is not a general exemption for every small seller or a blanket rule based on a seller’s total California revenue. CDTFA’s digital-products guidance describes a $5 million aggregate gross-receipts threshold for digital products transferred electronically or accessed remotely, measured for sales by a retailer to the same purchaser. The threshold amount is subject to adjustment based on the California Consumer Price Index.
CDTFA states that when the threshold is exceeded, the purchaser becomes responsible for use tax on the transaction that causes the retailer to exceed it, and the retailer is relieved from the specified tax liability or collection obligation for that purchaser as provided by law. The timing and measurement rules vary by calendar year, including a change beginning in 2028. The threshold does not remove the need to track sales by purchaser or assess other taxable transactions. Check CDTFA’s current digital-products guidance for the applicable year and confirm how it applies to your customer records.
How to source sales and determine the applicable tax rate
For a taxable sale, identify the delivery or use location required by California’s sourcing rules and retain the address information used to make that determination. California layers district taxes on top of the statewide rate, so the total rate can vary by destination down to the street address. Do not apply a single California rate to every customer simply because the seller is based in California or because the customer is in the same state.
The statewide rate is currently 7.25%, before any applicable district tax. CDTFA provides a rate lookup by address and publishes current city and county rates. Use the customer’s relevant delivery address in that lookup, and recheck rates as needed because district rates can change. If the transaction is a remotely accessed digital product, first determine whether it is taxable under the applicable digital-products rule; sourcing a nontaxable sale does not make it taxable.
When to register and obtain a California seller’s permit
Retailers required to collect California sales tax must register with CDTFA and obtain the appropriate seller’s permit before making taxable sales. Registration is completed through the CDTFA online services portal. Whether an out-of-state seller must register depends on its activities, sales, and the rules applicable to the products it sells. The threshold for digital products described above is a separate, purchaser-specific rule and should not be confused with California’s economic-nexus rules for tangible personal property.
Review your product catalog, customer locations, physical presence, and sales channels before deciding whether registration is required. If you already hold a permit, update your account and reporting practices when your business or tax obligations change. CDTFA’s current registration guidance should be checked for the exact requirements and timing in your circumstances; Sales Tax Compliance USA can help assess the facts and manage the registration process.
How to file returns and remit California sales tax
Registered sellers file sales and use tax returns with CDTFA and remit the tax due. CDTFA assigns a filing frequency and provides return and payment instructions through its online services. Report sales, taxable amounts, deductions, and tax collected accurately, including transactions that are exempt or nontaxable where the return requests them. Do not assume that a digital-products exception eliminates reporting or recordkeeping duties.
Filing frequency and due dates are account-specific and can change. Use the filing schedule and deadlines shown by CDTFA for your account rather than relying on a generic calendar. Reconcile sales records, customer locations, tax calculations, exemption documentation, and payments before filing. If you sell through multiple channels or across borders, keep the California reporting separate enough to support a clear return calculation.
Exemption certificates and records to keep
Keep documentation for every deduction or exemption claimed, including applicable exemption or resale certificates, invoices, contracts, product descriptions, and evidence of how a digital product was delivered. For digital-product exceptions, records should support the specific basis claimed—for example, that software was custom, that a product represented a service, or that it was purchased solely for use outside California. A label on an invoice alone may not establish the facts.
CDTFA requires businesses holding a permit or other CDTFA account to maintain records supporting their tax reporting. Its guidance says records must generally be kept for at least four years; records relevant to an audit should be retained until the audit is complete even if that takes longer. Keep sales and purchase records, return workpapers, exemption documents, and address and transaction data in an organized, retrievable form.
Prepare your business and get help with California compliance
Start by mapping each product to its actual delivery method and features: prewritten software, custom development, hosted access, digital content, services, or a bundle. Identify California customers, capture the address information needed for sourcing, and track digital-product receipts by purchaser so you can evaluate the threshold. Review contracts and invoices for physical media, service components, and rights granted to customers. Then confirm whether registration, collection, and filing obligations apply under the rules in force for the relevant period.

Are digital products taxable in California?
Under current treatment, digital products transferred electronically are generally not taxable when the purchaser receives no tangible personal property. The new law brings qualifying digital products into the tax base, subject to exceptions such as qualifying custom software and digital products representing services other than SaaS, as well as the threshold rules.
Is custom software subject to California sales tax?
CDTFA identifies custom computer software as an exception under the new digital-products law. The classification depends on the facts: software initially developed as custom work may still be treated as prewritten if it is held or exists for general or repeated sale or lease. Keep contracts and development records that support the classification.
Are e-books, music, and streaming services taxable in California?
Under current CDTFA guidance, digital books and other electronically transferred data are generally not taxable when no tangible property is provided. The new law changes the treatment of qualifying digital products, while digital products representing a service are excepted other than SaaS.

Does California sales tax apply to cloud software accessed remotely?
Under current rules, charges for software accessed remotely are generally not taxable when the customer receives no tangible personal property. The new digital-products framework includes prewritten software accessed remotely, including SaaS, subject to exceptions and the threshold. Review the product and applicable year rather than treating all cloud services alike.
Do SaaS companies need to collect California sales tax?
Some may, depending on the applicable digital-products rules, the product, the purchaser-specific threshold, and the seller’s California registration obligations. The threshold is measured by aggregate digital-product receipts from the retailer to the same purchaser, not simply by the seller’s total revenue. Review your customer-level sales and registration facts with CDTFA or a compliance professional.
What California sales tax rate applies to SaaS?
First determine whether the SaaS transaction is taxable for the relevant period. If it is taxable, California’s statewide rate is 7.25% before applicable district taxes, and the total rate depends on the relevant address. Use CDTFA’s address-based rate lookup; do not assume one statewide total rate applies everywhere.
