Prepare Before January 1
Your software company may need to start charging California state tax on subscriptions that previously generated no sales tax. Your business may also need to report use tax on software purchases even when the vendor sends an invoice without a sales tax charge. An automatic renewal or an unchanged billing system can conceal a significant change in your California Sales Tax obligations.
Beginning January 1, 2027, California state expands its sales and use tax treatment of prewritten software, including software as a service (SaaS). Senate Bill 122 brings electronically delivered and remotely accessed software within the state’s definition of taxable tangible personal property, subject to applicable exclusions and exemptions.
The distinction between the law and its implementation matters. As of November 3, 2026, the California Department of Tax and Fee Administration (CDTFA) still describes its implementing emergency regulations as drafts. The Legislature has enacted the expansion, however, and businesses should prepare for the January 2027 operative date while monitoring the final rules.
At the Tax Law Offices of David W. Klasing, our dual-licensed tax attorneys and CPAs can review what you sell or purchase, determine which transactions require attention, and help you develop a defensible California state sales and use tax position before billing and reporting errors accumulate.
Which Software and Digital Products Will California State Tax?
The new law reaches prewritten software whether the seller supplies it on physical media, transfers it electronically, or provides remote access. For SaaS businesses, the relevant transaction can involve a customer’s right to use the provider’s prewritten software through a browser or other interface. Calling the arrangement a subscription or a license does not establish an exemption.
The law does not impose a blanket tax on all digital content. It excludes defined categories of digital assets, audio and audiovisual works, books, infrastructure, entertainment video games, and visual works. These exclusions have specific boundaries. A business should examine what its customer actually receives before relying on a product label.
For example, qualifying digital infrastructure allows customers to create, deploy, scale, or run their own software on the provider’s platform. That can include qualifying Infrastructure as a Service (IaaS) and Platform as a Service (PaaS). It differs from purchasing access to the provider’s prewritten application.
Custom software also requires a separate analysis. Qualifying software prepared to a single customer’s special order remains outside the taxable sale-and-purchase definition, subject to the statutory requirements. Separately stated charges for genuine custom modifications can receive different treatment from the underlying prewritten program. Developing a program originally for one customer does not preserve custom treatment if the seller later holds it for general or repeated sale.
CDTFA’s draft illustrates another important distinction: an AI platform marketed to multiple customers does not become custom software merely because it generates individualized results.
Likewise, the human-effort service exemption requires more than customer support or an employee’s involvement. The service must primarily involve human effort that originates after the customer requests it. The exemption expressly excludes the right to use the provider’s prewritten cloud software or access that software through the specified interfaces.
A vendor that bundles software, implementation, and custom development should therefore review both the agreement and its invoices. Identify the actual work, preserve development records, and determine whether the pricing supports the claimed treatment. An invoice description alone cannot replace that analysis.
Software reproduction and distribution rights also deserve review. The law specifically exempts qualifying rights to reproduce or copy a digital product for distribution to third parties for consideration. An ordinary end-user license does not necessarily grant those rights.
A Contract Signed in 2026 Does Not Automatically Avoid the 2027 Tax
Do not assume that signing early or prepaying guarantees tax-free access during 2027.
The draft timing rules focus on when the purchaser receives the right to use the software. One example treats a December 2026 payment as taxable when access rights begin January 1, 2027. Another treats a monthly subscription as a continuing sale, with tax applying to subscription periods beginning in 2027.
Before renewing or restructuring an agreement, review its commencement date, access rights, payment obligations, and subscription terms together. A financed purchase and a recurring subscription can present different questions. Preserve the executed agreement and the records showing when the customer actually obtained the contractual rights.
Sellers should also review who bears the economic cost. California generally imposes sales tax on the retailer. Whether the retailer may add reimbursement to the customer’s price depends on the agreement and applicable rules. An existing fixed-price commitment can therefore create a margin problem if the seller cannot pass the tax through.
Buyers should review renewal notices and proposed tax clauses before approving them. Ask which products the vendor treats as taxable, how it calculated the California portion, and whether the contract separately identifies custom work or other potentially exempt components.
The goal is to establish the correct treatment before the parties disagree over an invoice or CDTFA questions a return.
The $5 Million Rule Shifts Responsibility; it Does Not Create an Exemption
A particularly consequential provision affects large software purchases.
When qualifying electronic or remotely accessed digital-product sales from one retailer to the same purchaser exceed $5 million, responsibility generally shifts from the retailer to the purchaser. For 2027, the test looks at that calendar year. Beginning in 2028, it considers the current or preceding calendar year. The law includes exceptions and permits CDTFA to approve a waiver in qualifying circumstances.
This is not a $5 million tax-free allowance. It also does not mean that a purchaser combines spending across every software vendor to determine whether it crossed the threshold.
The shift begins with the transaction that crosses the threshold. A purchaser subject to direct reporting generally must obtain a Use Tax Direct Payment Permit, provide the required certificate to the retailer, and report and pay the applicable use tax directly to CDTFA.
An enterprise purchaser should assign responsibility for monitoring vendor spending before the first reporting period. Procurement may approve the agreement, accounts payable may process the invoice, and the tax department may prepare the return. Those teams need a shared understanding of when direct reporting begins.
Smaller purchasers also need to review their invoices. A taxable California software purchase can generate use tax obligations when an out-of-state seller does not collect the tax. The absence of a tax charge does not establish an exemption.
Multistate Software Use Requires More Than an Out-of-State Address
A California business may license software for employees across several states. Another company may maintain its headquarters elsewhere while California personnel use the application daily. These arrangements require an analysis of the applicable sourcing rules and the actual use.
For remote sales, the law establishes a hierarchy of purchaser addresses in the seller’s records, beginning with a qualifying California billing address. Sellers must make reasonable efforts to obtain accurate, complete address information to qualify for the relevant statutory relief.
CDTFA’s proposed multiple-points-of-use rules allow reasonable, consistent allocation supported by records. User or computer counts can qualify; server location alone cannot. A qualifying certificate would relieve the seller only for the supported non-California portion.
Start gathering user-location information, license assignments, contracts, and allocation records now. Where employees move, or teams share access, examine whether the records still support the method you intend to use. Do not assume that a vendor’s headquarters, an out-of-state server, or a nationwide license answers the California tax question.
How the Tax Law Offices of David W. Klasing Can Help Your Business Prepare
The useful question is whether your contracts, accounting records, and tax reporting support the same treatment. A legal conclusion that never reaches the billing system will not prevent incorrect invoices. An accounting setting cannot establish an exemption that the underlying transaction does not support.
At the Tax Law Offices of David W. Klasing, our dual-licensed Tax Attorneys & CPAs can help you:
- Classify your products and purchases: We can examine software functionality, license rights, custom development, and service components against the applicable law.
- Review contracts and invoicing: We can analyze renewal dates, tax reimbursement provisions, bundled charges, and documentation supporting your position.
- Evaluate registration and reporting obligations: We can assess your California connection, purchaser use tax exposure, direct-payment requirements, and applicable local and district tax issues.
- Substantiate multistate treatment: We can review allocation methods, user-location records, and exemption certificates.
- Prepare for or respond to a civil tax audit: We can examine CDTFA’s position, organize supporting evidence, manage agency communications, and evaluate available administrative remedies.
Where a material classification question remains unresolved, we can also evaluate whether requesting written advice from CDTFA would help. CDTFA explains that qualifying written advice may protect against certain liabilities when the agency gives erroneous advice; oral guidance does not provide the same protection. The request must accurately describe the transaction and satisfy the applicable requirements.
Waiting until a missed filing or payment deadline can add interest and applicable penalties to the underlying tax exposure. Addressing the classification, contract, and reporting questions now gives your business time to implement a supported position.
