The answer appears simple – subscription AI chatbot services either fall within a state’s existing sales tax structure for Software as a Service (SaaS), or they don’t. However, as with digital goods and streaming services in the past, attempts by a few states to fit new technologies into an existing legal framework can be as awkward as an ocean liner taking on a slalom course.

How are SaaS transactions currently taxed? 

The basic concept of a SaaS transaction is that the purchaser is accessing a software application via the internet. Within this, there is a junk drawer full of variables that may determine the fate of SaaS’s taxability in a state. These can include: (1) type of software license agreement; (2) the definition of tangible personal property (TPP), service, software, or digital good; (3) type of user; and (4) whether SaaS is bundled with other digital goods or services.  

To that extent, some states that sought to subject SaaS to sales tax have often concentrated on fitting SaaS into the definition of TPP, software, or other taxable services. Take Kentucky, wherein Kentucky Tax Facts No. 1/20/2026 the state provides SaaS is considered “prewritten computer access services” and therefore a taxable service, “even with Artificial Intelligence (AI) components”. 

Others differentiate SaaS from the definitions mentioned above and choose to exempt the transaction. For example, Indiana Revenue Ruling 2025-02-RST, states, “SaaS is not taxable in Indiana” since accessing prewritten computer software via the internet with no possession interest is not subject to sales tax.  

With respect to subscription AI chatbot services, the ruling centered around similar logic by adding “the AI is accessed electronically with no permanent ownership aspect, the AI would not be subject to sales tax.” These states illustrate a fairly straightforward application of existing law but also that the simple answer of today may soon become the ambiguity of tomorrow as products become increasingly complex. 

The Maine Case: Why SaaS Tax Rules are Evolving

To understand how a state may struggle in addressing AI in the future, one can look at Maine’s recent tango with SaaS.  Maine created ambiguity in 2025 when it updated its law on the tax treatment of leases without addressing whether the state was subjecting SaaS software licenses to sales tax.  

Maine historically treated software licenses (if not perpetual or for more than 10 years) as leases that were taxable to the lessor. This meant that tax was not collected at the time the lessor executed a license agreement, but rather on the lessor’s acquisition cost. Thus, the lessee/end user did not pay sales tax at the time of purchase and therefore, software licenses for SaaS were likewise understood as nontaxable to the to the lessee

In early 2025, Maine passed LD 2214/HB 1420 providing that leases, including licenses, are treated in the same manner as TPP.  However, the statute did not address the sales tax treatment of SaaS.  Was SaaS considered TPP and would SaaS licenses be taxed as other software licenses?

Maine then approved Rule 326 in October 2025. These regulations directly stated that licensed software which is remotely accessed over the internet is not subject to sales tax, thus carving out SaaS software licenses from other licenses which were seen as taxable TPP and holding the position that SaaS licenses are neither tangible nor taxable.   

The Maine scenario illustrates that as new laws are passed, states may lose sight of the impact it has on existing digital age products, let alone more modern product offerings such as AI chatbots. Adjusting tax structures to accommodate these new offerings may require innovative approaches, new definitions, or even additional carve outs. 

Sales Tax on Future AI Services  

Adapting an existing tax structure to modern products as demonstrated above is often ponderous and will inevitably occur more often with future advancements. Suppose a company offers the ability to purchase an AI powered humanoid or physical AI (e.g. Tesla’s Optimus Robot).  

It has the ability to “learn” about consumer needs: it can do your chores, tutor your children in algebra, or repair plumbing. If a jurisdiction applies the “true object” test, what is the primary purpose of the transaction? Is it in the robot or the underlying services the AI enabled robot can perform?

A state could simply argue that the robot is the primary purpose of the transaction as the sale of TPP irrespective of the services it’s designed to perform. Generally, sales of TPP are taxable and therefore the transaction is subject to tax. On the other hand, a jurisdiction could provide that the primary purpose is the services offered, and the robot is rather a medium for those services. In many tax structures, services are exempt and could lead to an exempt result. 

It gets more complex if a state concentrates on the software itself. Consider the Matter of Beeline.com, Inc. v. N.Y.S. Tax App. Trib. Here, the petitioner offered a service of pairing temporary labor with businesses and argued this arrangement was a nontaxable service transaction.  

However, as part of the petitioner’s contract offering to businesses, petitioner provided a license to prewritten software which assisted the businesses in facilitating the temporary labor pairings. The court found that the taxable license to prewritten software was the primary purpose of the transaction, not the argued nontaxable service.   

The petitioner also argued in this context, “that its software is not prewritten because it is tailored to each client’s needs,” and therefore exempt as customized software. This was dismissed by the court too, which found that the software only adjusted documents and did not result in customization for users. 

In our scenario, the AI-powered humanoid is capable of “learning” from its individual users. Activities such as tutoring or performing chores seem to involve a higher degree of user-specific engagement compared to document adjustments. Under these circumstances, might a court determine that the SaaS offering is sufficiently customized in real time to potentially qualify for exemption? 

What Businesses Should Know About AI Sales Tax Compliance

These questions appear novel, but they demonstrate how closing one door in a tax structure can open several others. As AI services evolve beyond chatbots into physical applications that blur the line between tangible property and intangible services, states will face mounting pressure to move beyond retrofitting existing definitions and instead develop clear, forward-looking guidance. 

For businesses operating in this space, the takeaway is practical: monitor state-level developments closely. History suggests legislatures will address these complexities slowly and unevenly, and staying ahead of the curve requires attention, adaptability, and a willingness to engage with the ambiguity that comes with operating at the intersection of tax law and technological innovation.
