3 Sales Tax Myths About Services You Should Stop Believing

Sales tax treatment of services is frequently shaped by assumptions rather than by how states actually apply the law. In a landscape that depends on precise interpretation, relying on those assumptions can quickly create unintended risk. States increasingly focus on the substance of a transaction rather than on how it is labeled, priced, or described, which means common approaches could result in tax exposure.  

These assumptions tend to show up in the same recurring ways. Quick labels are used in place of thorough classification, line items are expected to control the outcome, and exemptions are often treated as fixed rather than fluid. Each of these beliefs feels logical on the surface, which is why they persist, but they can create a false sense of certainty when applied across numerous jurisdictions and transaction types. As service offerings continue to evolve, especially when combined with technology, these myths become even harder to rely on. 

Taken together, these myths highlight a consistent theme. Sales tax outcomes depend on how value is delivered, how transactions are structured, and how state rules evolve. 

Myth 1: “If we call it a service, it’s taxed as a service.” 

Labeling a transaction as a “service” on a contract or invoice does not determine its tax treatment. While invoice language and itemization can influence how a transaction is evaluated, they are not controlling factors. 

States look beyond how a transaction is described and instead focus on what the customer actually receives. This analysis is often grounded in the true object test, which evaluates the transaction’s primary purpose. If the customer’s intent is to obtain a taxable good or access to software functionality, the entire transaction may be characterized as the underlying item, even if it is presented as a service. This demonstrates a broader shift toward evaluating the economic reality of the transaction rather than relying on form or terminology. 

This is especially important in states without explicit rules for SaaS or technology-based offerings. In those cases, if the underlying value delivered is the use of software, many states will treat the transaction as a sale of software, regardless of how it is labeled or marketed. 

Case law and administrative rulings reinforce this approach, as the states have been taking this position for at least the past ten years. For instance, the Indiana Department of Revenue determined that an advertising company’s provision of direct mail services constituted a taxable unitary transaction because the customer received tangible personal property along with related services for a single charge. The company argued that the true object was an exempt advertising service, but the state concluded that the combined nature of the offering made the full amount subject to tax (Letter of Findings No. 04-20150410, May 25, 2016). 

The key takeaway is clear: taxability and characterization can vary based on how value is delivered to the customer, not how the transaction is labeled. 

Myth 2: “Putting the software on its own line item keeps the service portion exempt.” 

The bundling trap. Separately stating charges are often viewed as a way to isolate taxable components, but it is not the same as genuinely unbundling a transaction. When software, implementation, maintenance, and training are offered simultaneously, simply listing them as separate line items but on a single contract and invoice does not automatically change how the transaction is treated. If those components are not truly distinct or offered separately, particularly if they are required to complete the sale, many states will still view the transaction as a single bundled sale, which can result in the entire amount being subject to tax. 

This becomes progressively more nuanced in states that follow the Streamlined Sales and Use Tax Agreement. Streamlined Sales Tax member states are required to define how bundled transactions are treated in their taxability matrices, which adds structure but not necessarily more flexibility. Under Section 330(D)(3) of the Agreement, states may apply uniform allocation rules to mixed transactions rather than accepting a taxpayer’s separate line items at face value. As a result, even well-intentioned attempts to break out taxable and nontaxable components may not be respected if the overall transaction is still viewed as a bundled sale. The outcome depends not just on how charges appear, but on whether the components are substantively distinct and recognized as such under state rules. 

Myth 3: “An exempt service stays exempt.” 

Exemption status is not permanent, and relying on prior treatment creates risk as states revisit and revise their rules. Exemptions can be narrowed, repealed, or allowed to expire entirely as policy priorities shift. For example, Texas ends its sales and use tax exemption for research and development equipment purchases on January 1, 2026, shifting those transactions into taxable territory. Maryland also moved in this direction by eliminating its exemption for SaaS for commercial use as of July 1, 2025. These changes illustrate that exemption status can be actively rolled back, even in areas long treated as exempt. When businesses continue applying prior treatment without monitoring legislative updates, the result can be unexpected tax exposure. 

At the same time, the landscape is not determined solely by the removal of exemptions. States are also introducing and expanding exemptions in targeted ways. Iowa’s HF 960 widens its exemption for telecommunications and internet access services by covering certain central office and transmission equipment. Maryland provides another example: after eliminating its broad SaaS exemption for businesses in 2025, the state turned around in 2026 and added a narrow new exemption under HB 898 for data and IT services sold between affiliated group members. 

Taken together, these changes show that exemption status is constantly evolving, with expansions and repeals often occurring in parallel rather than in isolation. 

Ready to Go Beyond the Myths? 

The myths explored here persist because they feel intuitive, but as the examples show, they rarely hold up when applied to real-life transactions throughout various states. Services are among the most difficult areas of sales tax, as they are currently in the crosshairs of states attempting to capture revenue from modern business practices. What counted as compliant in the past can quickly become outdated as business models change and states refine definitions, reinterpret transactions, or change the scope of exemptions. In that environment, it becomes easy to mistake familiar narratives for reliable guidance. 

This is where deeper analysis becomes critical. Understanding how to evaluate the true object of a transaction, properly structure bundled offerings, and track the lifecycle of exemptions requires more than surface-level rules. It requires a clear structure for interpreting how states apply tax law in practice, especially as services and technology continue to converge.
