In California, electronically delivered software, digital books, mobile applications, and other digital products are generally not subject to sales tax when transferred over the Internet. However, transactions involving physical media or printed copies are generally taxable. This article explains California sales tax rules for software, SaaS, and digital products, including the importance of delivery method and transaction structure.

California SaaS Sales Tax: Electronically Delivered Digital Products Are Generally Non-Taxable
California treats software and digital products differently from many states.
The California Department of Tax and Fee Administration (CDTFA) states that sales of electronic data products, including:
- software;
- data;
- digital books (eBooks);
- mobile applications;
- digital images;
are generally not taxable when transmitted electronically over the Internet.
The key factors are:
- delivery method;
- whether physical media is included;
- whether tangible items are provided.
Electronically Delivered Software Is Generally Non-Taxable
When software is transferred electronically and no physical medium is provided, the transaction is generally not subject to California sales tax.
Example:
Software download USD 500
Customer receives:
- online download;
- no USB;
- no CD;
- no physical backup.
The transaction is generally non-taxable.
Digital Books and Mobile Applications
California also treats certain electronically delivered digital products differently from tangible goods.
Examples:
eBook download USD 20
Mobile application download USD 5
When delivered electronically without physical media, these transactions are generally not taxable.
Physical Media Changes the Tax Treatment
California generally treats transactions differently when tangible items are included.
Example:
Software download USD 500
Plus:
USB backup copy USD 20
When a physical backup copy is provided as part of the transaction, the entire sale is generally taxable.
The same applies to:
- CDs;
- flash drives;
- printed copies.
SaaS and Remote Software Access
California’s current approach generally does not tax software accessed remotely or electronically delivered digital products.
Examples include:
- cloud software platforms;
- online business applications;
- hosted software solutions.
However, businesses should review whether transactions include taxable tangible items.
Canned Software vs. Custom Software
California distinguishes between:
- canned (noncustom) software;
- custom software.
CDTFA explains that canned software downloaded from a server is generally not subject to tax when no physical medium is provided.
However, providing a physical backup copy changes the treatment.
Common California SaaS Compliance Issues
Assuming all SaaS is taxable
California generally does not tax electronically delivered software in the same way as states that classify SaaS as taxable software.
Providing physical backups
USB drives, CDs, and printed materials may change the tax treatment of the entire transaction.
Mixing digital and tangible products
Digital subscriptions combined with physical deliverables require additional review.
Failing to document delivery method
Businesses should maintain clear records showing whether products were electronically delivered or physically transferred.
Compliance Tips for SaaS Businesses
Businesses selling software or digital products to California customers should:
- Document the delivery method;
- Separate digital products from tangible items;
- Clearly identify physical deliverables on invoices;
- Maintain contracts, order records, and delivery documentation;
- Monitor California legislative developments.
Future California SaaS Tax Changes
California currently generally does not impose sales tax on electronically delivered software and digital products.
However, Governor Gavin Newsom’s 2026-2027 budget proposal would apply sales and use tax to certain digital product transactions, including:
- electronically transferred software;
- remotely accessed software;
- software as a service (SaaS).
If enacted, this would significantly change California SaaS taxation.
Businesses should continue monitoring California legislative updates and CDTFA guidance.
Conclusion
California generally treats electronically delivered digital products differently from tangible goods.
Key rules:
- electronically delivered software is generally non-taxable;
- downloaded software is generally non-taxable;
- eBooks and mobile applications delivered electronically are generally non-taxable;
- physical media, printed copies, or backup copies can make the entire transaction taxable.
For SaaS businesses, California tax treatment depends heavily on delivery method and whether tangible items are included.
