Does California’s digital products sales tax apply to SaaS?
A short email from the California Department of Tax and Fee Administration to interested-parties subscribers this month has been quietly rewriting the calendar for California software companies. Beginning January 1, 2027, the state’s sales and use tax will apply to prewritten computer software delivered on physical media, downloaded electronically, or accessed remotely. That last category is the one that changes the map: for the first time, retail sales of prewritten Software-as-a-Service to California customers will be taxable. The digital products sales tax created by Senate Bill 122 (Stats. 2026, ch. 23) expands the definition of tangible personal property under the Sales and Use Tax Law and reaches sellers and buyers who have never had to think about the return form before. In this post we walk through what changes, what stays exempt, and what a California SaaS provider — or a $5-million-a-year purchaser — needs to do this quarter to be ready.
What is California’s new digital products sales tax? 📱
It is a legislative expansion of the definition of tangible personal property that pulls prewritten computer software and associated copyright or patent interests into the sales and use tax base beginning January 1, 2027.
The CDTFA notice describes the change plainly: the definition of tangible personal property in the Sales and Use Tax Law will be expanded to include digital products and any copyright or patent interests associated with those digital products. Once the definition changes, the ordinary sales and use tax mechanics apply. Retail sales of digital products made in California, and the storage, use, or other consumption in California of digital products purchased from any retailer, may be subject to sales or use tax at the applicable state, local, and district rate.
The statutory vehicle is Senate Bill 122 (Stats. 2026, ch. 23), which was signed into law on June 29, 2026. The bill’s text and legislative history are accessible through the California Legislative Information portal. The operative date built into the legislation is January 1, 2027 — meaningful because it lets sellers, purchasers, marketplace facilitators, and system vendors work through invoicing, tax-engine mapping, and contract-language changes in the last two quarters of 2026.
A digital product, as defined by the new rule, is prewritten computer software transferred on tangible storage media, transferred electronically, or accessed remotely. Prewritten computer software is software held or existing for general or repeated sale or lease — even if it was initially developed on a custom basis or for in-house use — and includes the combination of two or more prewritten programs. That language is broader than the older physical-media rule and captures the modern software business model: downloads, subscriptions, and remote-access services.
Who is affected — SaaS providers, resellers, and large purchasers 🧾
Sellers of prewritten software, SaaS providers, businesses that license or provide remote access to prewritten software, and, at higher volumes, the purchasers themselves.
The CDTFA identifies four groups affected by the new definition, and each has a different implementation checklist:
- Sellers of prewritten computer software. Traditional software vendors — regardless of whether the product ships on media, is downloaded, or is delivered by an activation key — will need to charge, collect, and remit California sales or use tax on retail sales beginning January 1, 2027.
- Prewritten Software-as-a-Service (SaaS) providers. This is the biggest practical change. A SaaS subscription that has historically been treated as a nontaxable service in California will fall inside the digital products definition when the software is prewritten and accessed remotely.
- Businesses that license or provide remote access to prewritten software. Reseller and licensing arrangements that pass through prewritten software are pulled in, including many indirect channels and marketplace-style deals.
- Purchasers of digital products. In-state purchasers face a new tax on prewritten software; large-volume purchasers may take over the collection role themselves under the $5 million threshold discussed below.
Out-of-state sellers are not exempt just because they lack a California physical footprint. A seller “engaged in business in this state” as defined in Revenue and Taxation Code section 6203 must register with CDTFA for a Certificate of Registration for Use Tax, collect use tax on retail sales of digital products sold to California consumers, and remit it. The economic-nexus thresholds that California has applied to tangible goods since Wayfair carry over into this new category.
What digital products are outside the new California digital products sales tax? 🚫
Several digital-media categories are excluded from the definition, and a separate set of exemptions covers custom software, services, and out-of-state use.
Two lists in the CDTFA notice deserve close reading — the first tells you what is not a digital product at all, and the second tells you what is a digital product but is nonetheless exempt from the tax.
| Category | Treatment | Notes |
|---|---|---|
| Digital assets (e.g., cryptocurrency) | Not a digital product | The new rule does not turn crypto tokens or NFTs into tangible personal property. |
| Digital audio (music, spoken recordings, ringtones) | Not a digital product | Streaming and downloaded music is outside the digital products definition. |
| Digital audiovisual works (movies, videos with sound) | Not a digital product | Downloaded and streamed film and television stay out of scope. |
| Digital books (ebooks) | Not a digital product | Ebook sales are unaffected by SB 122. |
| Digital infrastructure (IaaS/PaaS platforms) | Not a digital product | Cloud platforms that let customers create, deploy, or run their own software applications are excluded. |
| Digital video game products | Not a digital product | Video game downloads and in-game purchases are outside the definition. |
| Digital visual works (computer-generated artwork) | Not a digital product | Standalone digital art, images, and design files are excluded. |
| Custom computer software | Digital product but EXEMPT | Software written for a single customer and not held out for general sale stays exempt. |
| Digital products representing a service (not SaaS) | Digital product but EXEMPT | Where the true object is a service rather than software, the transaction remains exempt. |
| Digital products transferred with reproduction and distribution rights | Digital product but EXEMPT | Bulk transfers with sublicensing rights are carved out. |
| Digital products purchased solely for use outside California | Digital product but EXEMPT | Documentation of the out-of-state use is essential to support the exemption. |
The custom-software carve-out is the one most likely to be misapplied. Software that started as a custom build but is later resold, licensed, or repackaged for other customers becomes prewritten under the definition. Firms whose engagement letters let them reuse code across clients need to look at whether the finished product is still custom in the CDTFA’s sense on the date of each sale.
From our practice: the object test, not the invoice line, decides
In our practice, the hardest calls are not “is this SaaS?” but “is this really software, or is it a service?” A hosted platform whose real value is the human expertise it delivers — legal review, medical triage, tax preparation — is closer to an exempt service than to a taxable digital product, even when the customer touches it through a web app. Where the true object is professional service, document that conclusion contemporaneously; where the true object is standardized software, plan for tax. The invoice line item is not what the CDTFA will look at first.
How does the $5 million threshold shift the collection burden? 💼
When a single purchaser buys more than $5 million of remotely delivered digital products from a retailer in a calendar year, the collection obligation may shift to the purchaser, who then registers for a Use Tax Direct Payment Permit and pays CDTFA directly.
The notice describes a threshold rule that changes the mechanics for large enterprise buyers. When the aggregate gross receipts from sales of digital products by a retailer to a single purchaser — transferred electronically or accessed remotely — exceed $5 million in a calendar year, or in the preceding calendar year, the tax liability may shift from the retailer to the purchaser. Once the shift takes place, the purchaser may be required to register for a Use Tax Direct Payment Permit and report the tax directly to the CDTFA.
For enterprise SaaS deals, this rule is significant on both sides. Sellers with a small number of very large California customers need to identify which relationships cross the $5 million line and rework the tax clauses in those contracts so that the obligation is aligned with the reality on the ground. Buyers whose annual spend with a single vendor is over $5 million need to plan for a new direct-pay registration, a new return, and internal controls to accrue and remit use tax on a running basis rather than expect it to appear on a vendor invoice.
Registration is not optional — and the CDTFA notice is not the statute
Digital-product sellers in California who are not already registered must obtain a seller’s permit, file sales and use tax returns, and report and pay tax on retail sales of digital products. Out-of-state sellers meeting the section 6203 definition of engaged in business in California must register for a Certificate of Registration for Use Tax. The CDTFA notice is a plain-language summary; the controlling text is Senate Bill 122 (Stats. 2026, ch. 23) and the underlying Revenue and Taxation Code. Watch CDTFA special notices and interested-parties bulletins for the emergency regulations that will fill in the operational details.
How do you report local and district tax on a remote SaaS sale? 🗺️
For digital products transferred electronically or accessed remotely, the place of sale — for local and district tax reporting — is generally the customer’s address, and the place of use is where the person accessing the product is located.
California’s sales and use tax combines a statewide rate with local and district add-ons, which is why address-based sourcing matters. Under the CDTFA guidance, the place of sale of digital products transferred electronically or accessed remotely is generally the customer’s address, and the place of use is where the person accessing the digital product is located. For a SaaS provider with subscribers across the state, that means aligning the tax engine to bill-to and ship-to (or in this context, access-to) addresses, and refreshing rate tables as districts change.
Where users access a subscription from multiple counties or districts — a common pattern for corporate seats — the sourcing question requires contract-level and, sometimes, seat-level analysis. Building the data model now, while there is still time to reissue quotes and update customer master data, is far cheaper than a post-launch remediation.
What should California software businesses do before January 1, 2027? ✅
Map current offerings against the new definitions, register or update permits, recut contracts, program the tax engine, and set an internal cutover plan for the first invoice cycle in 2027.
- Inventory every product line. Flag each SKU or subscription as prewritten software, custom software, service, digital media, or infrastructure, and document the reasoning against the CDTFA categories.
- Reconfirm registration status. Confirm your California seller’s permit or Certificate of Registration for Use Tax is active. Out-of-state sellers should re-test economic nexus under section 6203 with the digital-product revenue now added to the mix.
- Identify $5 million purchasers. Pull the top-customer report and note which single-purchaser relationships cross the threshold, then decide whether the direct-pay mechanic will apply and whether contracts must be amended.
- Update tax engines and invoicing. Program the January 1, 2027 effective date, map SKUs to taxable-status flags, and validate address-based sourcing against the CDTFA rate tables for California destinations.
- Refresh customer-facing contracts. Add or update tax clauses so the responsibility for collection, direct-pay elections, and pass-throughs is explicit; grandfathering language for pre-2027 subscriptions should be considered.
- Train sales, billing, and support. The customer questions about why a SaaS invoice suddenly carries California sales tax will land on the front line first; a short internal FAQ prevents ad-hoc concessions.
Summary: California’s digital products sales tax at a glance
- Effective January 1, 2027, prewritten software — including SaaS and remote-access licenses — becomes a taxable digital product in California under Senate Bill 122.
- Custom software, non-SaaS digital services, digital-media categories (music, video, ebooks, video games, digital art), and digital infrastructure (IaaS/PaaS) stay outside the definition.
- When a retailer’s aggregate sales of remotely delivered digital products to a single purchaser exceed $5 million a year, the collection obligation may shift to the purchaser, who registers for a Use Tax Direct Payment Permit.
- Out-of-state sellers meeting the Revenue and Taxation Code section 6203 definition of engaged in business in California must register for a Certificate of Registration for Use Tax and remit use tax.
- For remotely accessed digital products, the place of sale is generally the customer’s address and the place of use is where the person accessing it is located.
Frequently asked questions about California’s digital products sales tax ❓
Q. When does California’s digital products sales tax take effect?
January 1, 2027. On that date, the definition of tangible personal property in the Sales and Use Tax Law expands to include digital products and any copyright or patent interests associated with them. Sales made or invoiced on and after that date fall under the new rule; transactions completed before then follow the prior law.
Q. Is SaaS taxable in California under the new rule?
Yes. A prewritten Software-as-a-Service offering — software that already exists for general or repeated sale and is accessed remotely — is a digital product under the new law. Retail sales of that access to California customers become subject to sales or use tax on January 1, 2027, unless a specific exemption applies.
Q. What counts as prewritten software for California sales tax?
Prewritten software is any computer software held or existing for general or repeated sale or lease, even if it was originally developed on a custom basis or for in-house use, and it includes any combination of two or more prewritten programs. It can be delivered on physical media, downloaded electronically, or accessed remotely — the delivery method is not the test.
Q. Which digital products are outside the scope?
The CDTFA lists several categories that are not “digital products” under the new definition, including digital assets such as cryptocurrency, digital audio and audiovisual works, ebooks, digital visual works, digital video games, and digital infrastructure such as cloud platforms that let customers create, deploy, or run their own software applications.
Q. What is the $5 million threshold and who does it affect?
When a retailer’s aggregate gross receipts from sales of digital products transferred electronically or accessed remotely to a single purchaser exceed $5 million in the current or preceding calendar year, the tax liability may shift from the retailer to the purchaser. In that case, the purchaser may be required to register for a Use Tax Direct Payment Permit and remit the tax directly to CDTFA.
Q. Does an out-of-state seller of digital products have to register in California?
If the out-of-state seller is engaged in business in California as defined in Revenue and Taxation Code section 6203 — for example, by meeting the state’s economic-nexus thresholds through sales to California customers — the seller must register for a Certificate of Registration for Use Tax, collect and report use tax on retail sales of digital products to California consumers, and remit it to CDTFA.
Q. Is custom software still exempt after January 1, 2027?
Yes. Custom computer software remains outside the new definition of a digital product. Software written for a single customer and not held out for general or repeated sale continues to be treated under the pre-existing rules. The exemption also covers digital products transferred with reproduction and distribution rights, and digital products purchased solely for use outside California.
This article is general information, not tax advice for your situation. The categorization of a specific product turns on facts and contract language, and the CDTFA is expected to issue additional regulations before the January 1, 2027 effective date.
