As the Software as a Service (SaaS) industry continues to grow, so do the complexities surrounding sales tax regulations. Understanding your obligations is crucial for SaaS businesses operating in the United States. 

In this guide, we’ll explore the states that charge sales tax on SaaS, why these regulations exist, and how you can navigate them effectively.


An Introduction to Sales Tax for SaaS

Sales tax is a consumption tax imposed by state and local governments on the sale of goods and certain services. While traditional tangible goods have always been subject to sales tax, the taxation of digital products, including SaaS, is a relatively new development.

You are obligated to pay sales tax in states where you have nexus and where SaaS is considered taxable. 

  • Physical nexus: You have a shop, warehouse, postal address or another form of physical presence in the state. This includes people working for the business, like 1099 contractors or any payrolled employees.
  • Economic nexus: Your sales to customers in the state reach the threshold specified by the authorities.

The Rules for B2C vs. B2C

In some states, the taxability of Software as a Service (SaaS) depends on whether it is used for business-to-business (B2B) or business-to-consumer (B2C) transactions. 

States can impose different tax treatments based on the nature of the use. B2B transactions sometimes qualify for exemptions or lower rates because governments want to encourage a business-friendly environment. B2C transactions are often taxed more heavily as they represent end-user consumption.

What's the difference between SaaS and a digital product?

SaaS provides software applications over the internet, accessible through a web browser, typically on a subscription basis. The SaaS provider handles hosting, maintenance, and updates, allowing users to access and use the software remotely. 

A digital product is usually a one-time purchase or download, such as an e-book, music file, or software application, which the user installs and uses locally on their own device. 

SaaS and digital products are taxed differently in many states. Make sure you define your product correctly to avoid getting caught out.


How to Calculate Your SaaS Sales Tax Rate

To calculate your SaaS sales tax rate, you'll need to consider the following factors:

  • The state and local tax rates applicable to your customers' locations
  • Whether the state taxes SaaS at the state level, local level, or both
  • Any applicable exemptions or special rules for SaaS in each jurisdiction
