Physical products are generally subject to sales tax in states that have one unless a specific exemption applies, and the rules for them are relatively well established. Digital products are a different story. States treat software, digital downloads, streaming, software as a service, and other electronically delivered products in widely varying ways. Some tax them like physical goods, some tax only certain categories, some tax them at different rates, and some do not tax them at all. Digital sales also raise harder questions about where a sale takes place and how bundled offerings should be taxed. For a business selling both types of products, assuming one set of rules applies to everything is one of the most common sources of sales tax errors.
This matters because the obligation to collect sales tax generally falls on the seller. If tax is not collected when it should have been, the business may have to pay it from its own funds, along with penalties and interest. One thing owners consistently underestimate is how quickly a growing digital product line can create exposure in states they never considered.
How Physical Products Are Typically Taxed
Sales tax was designed for tangible personal property, so the treatment of physical goods is the baseline in most states. Physical products are generally taxable unless a state exempts them, with common exemptions for certain groceries, prescription drugs, and items purchased for resale or by exempt organizations. When goods are shipped to customers, many states use destination-based sourcing, meaning tax is calculated based on where the item is delivered. Whether shipping and handling charges are taxable varies by state and sometimes depends on how those charges are presented on the invoice.
How Digital Products Are Typically Taxed
Digital products do not fall neatly into one category, and states often treat each type differently.
Digital Downloads and Digital Goods
Electronically delivered music, video, ebooks, images, and similar products may be taxed in some states, exempt in others, and defined differently from state to state. Some states have specific rules for digital goods, while others apply general sales tax rules or have not addressed certain categories directly.
Prewritten Software
Prewritten, or canned, software is often taxable when sold on a physical medium. When it is delivered electronically, treatment varies. Some states tax it the same way, while others treat electronic delivery differently. Custom software developed for a specific customer is often treated differently from prewritten software and may be exempt in many states, though definitions vary.
Software as a Service
Software as a service is one of the least consistent categories. Some states treat it as taxable software, some treat it as a taxable service, some tax only a portion of the charge, and many do not tax it. Related services, such as implementation, training, customization, and support, may be taxed differently from the subscription itself.
Streaming, Subscriptions, and Digital Services
Streaming services, online subscriptions, digital advertising, data processing, and information services are treated inconsistently, and several states have expanded the taxation of digital products and services in recent years. Because this area continues to change, rules that were accurate a year or two ago may no longer apply.
Where the Biggest Differences Lie
Sourcing: Where Does a Digital Sale Happen?
For physical goods, the delivery address usually answers this question. For digital products, there may be no shipping address at all. States often look to the customer's location, which may be determined from a billing address, account information, or other data. Business customers who use software in multiple locations can raise additional questions in some states. Collecting reliable customer location data is essential for applying the correct rules.
Bundled Offerings
Many businesses sell packages that combine physical and digital elements, or software with services. When taxable and nontaxable items are sold together for a single price, some states may treat the entire charge as taxable unless the components are separately stated or another rule applies. In practice, this usually shows up when a business sells a subscription that includes onboarding, support, or a physical device, and the invoice does not separate the pieces. How offerings are structured and invoiced can significantly affect the tax result.
Use Tax on the Buying Side
Businesses also purchase digital products, such as software subscriptions, and many of those vendors do not collect sales tax in every state. Where the purchase is taxable and tax was not charged, the buyer may owe use tax. This is an easy obligation to overlook, particularly for companies with many software subscriptions.
Do Nexus Rules Work the Same for Digital Sellers?
A question business owners often ask is whether selling only digital products avoids sales tax obligations in states where they have no physical presence. Generally, no. Economic nexus rules can require remote sellers to register and collect once their sales into a state exceed that state's threshold, and those rules can apply to digital sales. Which sales count toward a threshold, and whether taxable and nontaxable sales are both included, varies by state. Businesses that sell nationally should evaluate both nexus and product taxability together (see multi-state tax services).
Building a Compliance Process That Keeps Up
Managing sales tax for physical and digital products generally starts with a clear inventory of what the business sells. Each product or service should be classified, and its taxability determined for each state where the business has obligations, often in a product taxability matrix. Invoices and checkout systems should separately state taxable and nontaxable components where appropriate. Customer location data should be captured reliably at the point of sale. Exemption and resale certificates should be collected and stored for exempt customers.
Because the rules change frequently, a periodic review of product classifications is important, particularly when new products, pricing models, or bundles are introduced. Automated sales tax tools connected to billing and e-commerce systems can apply rates and rules consistently, but they are only as accurate as the product classifications and customer data they receive (see tax technology and system integrations). For technology companies and online sellers, getting this foundation right early is far easier than correcting it after several years of growth.
Where to Start
Sales tax rules for physical and digital products differ in what is taxable, where a sale is sourced, and how bundled offerings are treated, and the differences multiply across every state where a business sells. Treating digital products as if they follow the same rules as physical goods, or assuming they are never taxable, can both create exposure. If you sell digital products, physical products, or a combination of the two, reviewing your product taxability and multi-state obligations is a practical place to start.
