For years, many businesses viewed software and SaaS taxation as a relatively manageable area of state sales tax compliance. A company could determine whether a state taxed software and SaaS, apply the rule, and move on. That approach is quickly becoming outdated.
Across the country, several states are reevaluating how software, cloud-based platforms, and digital products and services fit within their sales tax frameworks. Some states are expanding taxability to capture modern technology offerings; others are broadening long-standing rules through legislation, administrative guidance, or court decisions. The result is a growing patchwork of rules that can significantly impact software providers, SaaS companies, and the businesses that purchase their products and services.
Recent developments in California, Colorado, New York, Texas, and Washington illustrate just how quickly the landscape is evolving.
California: A Fundamental Shift for Software and SaaS
Perhaps one of the most significant recent developments comes from California.
Historically, California’s sales tax regime focused largely on tangible personal property, which generally meant that sales of software and SaaS delivered electronically were not included in the sales tax base. That changes beginning January 1, 2027.
Under SB 122, California will treat prewritten software as taxable regardless of how it is delivered, whether on physical media, through electronic download, or via remote access. For many businesses, this effectively brings SaaS into the California sales tax base for the first time.
While custom software remains exempt, the legislation represents a major policy shift away from taxing physical software toward taxing software functionality and access. Companies selling into California will need to revisit taxability determinations, sourcing methodologies, customer data collection processes, and contract language well before the effective date.
For CFOs, the challenge extends beyond compliance. Software costs may increase where vendors begin collecting tax on subscriptions that were previously untaxed, creating new budgeting and procurement considerations.
Colorado: Preparing for a 2027 SaaS Tax Regime
Colorado is following a somewhat similar path, though through a different mechanism.
Today, Colorado remains relatively favorable to SaaS providers. Under current law, software generally is taxable only when it is prewritten, subject to a nonnegotiable license, and delivered on tangible media. As a result, SaaS and electronically delivered software have historically enjoyed favorable treatment at the state level.
That changes beginning January 1, 2027.
Legislation enacted through HB26-1223 will eliminate the delivery-method distinction that has historically driven Colorado’s software tax treatment. Prewritten software will generally be taxable regardless of delivery method, and SaaS is expected to become part of the state’s taxable base.
The transition period creates an important planning opportunity. Companies should review contract structures, licensing arrangements, and renewal timing before the new rules take effect.
Colorado’s home-rule city system adds another layer of complexity. Even before the statewide changes become effective, some jurisdictions already impose tax on software and SaaS differently than the state. Businesses operating across Colorado must therefore evaluate both state and local rules, not simply rely on statewide guidance.
New York: The Blueprint for SaaS Taxation
While California and Colorado are moving toward broader taxation of software, New York has been there for years.
New York continues to maintain one of the most expansive and consistently enforced frameworks for taxing software and SaaS. The state’s position is straightforward: prewritten software is taxable regardless of whether it is delivered physically, downloaded electronically, or accessed remotely through the cloud.
Recent litigation has reinforced that position. Courts have increasingly focused on the substance of transactions rather than how they are labeled. When software access is the core component of a transaction, New York is unlikely to allow taxpayers to avoid tax simply by characterizing the arrangement as a service.
This trend is especially important for businesses offering bundled solutions. Contracts that combine software, implementation, training, consulting, analytics, or support services may face increased scrutiny if taxable and nontaxable elements are not clearly delineated.
For multistate businesses, New York serves as a reminder that contract structure, user-location tracking, and documentation remain critical components of SaaS tax compliance.
Texas: The Expanding Reach of Data Processing Rules
Texas continues to take a distinctive approach to cloud technology taxation.
Rather than focusing primarily on software licensing concepts, Texas generally treats many SaaS offerings as taxable data processing services. This classification has become increasingly important following updates to Texas’ data processing rules.
The most notable development is not the creation of a new tax, but rather the state’s expanded interpretation of existing rules. Activities involving data hosting, analytics, payroll processing, platform services, and other technology-enabled offerings increasingly fall within the data processing framework.
That matters because Texas taxes only 80% of qualifying data processing charges, creating both planning opportunities and compliance challenges.
As SaaS platforms continue to incorporate automation, artificial intelligence, analytics, and data management functions, determining whether an offering constitutes taxable data processing or a nontaxable service becomes increasingly important.
For tax departments, defensible product classifications and well-documented allocation methodologies are becoming essential audit protections.
Washington: From Digital Products to Technology Services
Washington has long maintained one of the broadest digital taxation regimes in the country.
The state already taxes prewritten software, SaaS, remote access software, digital automated services, and many forms of digital content. Recent legislation, however, pushes Washington even further.
Through ESSB 5814, the state expanded taxation beyond digital products themselves and further into technology-related services. The expansion reaches areas such as IT support, help desk services, data processing, software implementation, website development, and certain software customization activities.
This shift reflects a broader trend emerging nationwide. Rather than focusing solely on whether software is taxable, states are increasingly evaluating the larger technology ecosystem that surrounds software deployment and use.
For businesses, that means taxability reviews must extend beyond software subscriptions and encompass implementation services, support arrangements, managed services, and other technology-related revenue streams.
The Bigger SALT Trend
While each state is taking a different approach, it is clear that several states are modernizing sales tax systems for the digital economy.
California is expanding taxability to SaaS. Colorado is preparing to do the same. New York continues to aggressively enforce existing software taxation rules. Texas broadened its data processing framework. Washington extended taxation deeper into technology-enabled services.
The practical takeaway for businesses is that software and SaaS taxability are no longer a simple yes-or-no question. Increasingly, the answers depend on:
- How a product is delivered
- How a contract is structured
- Where users are located
- Whether services are bundled with software
- How revenue is sourced
- Whether states classify an offering as software, a service, data processing, or something else entirely
The Bottom Line
For CFOs and tax leaders, the most significant risk may not be any single state’s rule change. It’s the cumulative effect of multiple states moving in different directions at the same time.
As software, SaaS, AI-enabled platforms, and digital services continue to evolve, tax departments should revisit taxability analyses, sourcing methodologies, customer-location data, invoicing practices, and contract structures. What worked a few years ago may no longer align with today’s sales tax rules.
