But as of 2024, the [Software as a Service (SaaS) industry was valued at $266 billion USD](https://www.fortunebusinessinsights.com/software-as-a-service-saas-market-102222) and is only gaining steam. But with great size comes great regulatory scrutiny. Especially when it comes to US sales tax. This indirect tax, once only charged on tangible goods like Stanley Cups and beard oil, is now digital, too. And the sweeping gaze of the sales tax auditor has recently fallen on non-compliant SaaS businesses. The bad news is that navigating US sales tax isn’t intuitive, especially on non-tangible goods like SaaS products. We talk to business owners every day who don’t realize they have to collect sales tax or who are bogged down in conflicting instructions on how and when to comply. This can lead to the worst decision: putting sales tax off until the auditor finds you first. The good news is that with a little strategy, handling sales tax in your SaaS business will become just another item on your to-do list, like paying payroll tax or planning the annual retreat, rather than a looming existential threat. Here’s what you need to know. ### Is SaaS Taxable in the US? #### Understanding US Sales Tax Law There’s no nationwide sales tax in the United States. Instead, sales tax laws are entirely up to individual states. Four friendly states don’t have a sales tax at all. But that just means that forty-six, plus Washington DC, all do. And each state, within constitutional limits, gets to set its own sales tax rates and make its own rules and regulations. Sales tax in the US is just what it says on the tin: a tax paid at the point of sale. Merchants, including SaaS businesses, charge sales tax to their customers at the point of sale and then remit the tax periodically back to the state. Sales tax makes up a large percentage of many state budgets, and lawmakers are eager to fill their coffers. States were initially slow to adapt when business went digital—remember when software meant physical CDs purchased from now-extinct electronics stores? But they've caught up to the digital revolution, updating their tax laws to capture revenue from virtual transactions, including your SaaS offerings. #### What Qualifies as Saas for Tax Purposes SaaS, for tax purposes, is software your customer accesses over the internet on a subscription basis without ever taking possession of the code. The customer logs in. They never download, install, or own a copy. Software like Salesforce, Slack, and Canva all work this way. That definition matters more than it sounds. States tax software categories differently, and the category your product lands in usually decides whether you owe tax at all. Before you look up your state in the table below, figure out which category you are actually in. - **Software as a service (SaaS)**: Software that is hosted centrally by you, accessed remotely by customers, and sold by subscription. Can be taxed very differently in different states, so it’s important to understate each state’s [SaaS](https://www.getsphere.com/blog/sales-tax-software) sales tax laws. - **Prewritten (canned) software:** Off-the-shelf software your customer downloads or installs, such as a licensed copy of Microsoft Office. Nearly every state with a sales tax treats prewritten software as taxable tangible personal property, even when it arrives electronically. - **Custom software**: Software written for one specific customer. Most states treat this as a non-taxable service. - **Infrastructure as a service (IaaS) and platform as a service (PaaS) software**: Infrastructure and platform services like Amazon Web Services and Microsoft Azure sell raw compute, storage, and development environments instead of a finished application. Some states tax these exactly like SaaS. Others treat them as nontaxable data storage or processing. - **Digital goods**: E-books, streaming video, music files, and digital images carry their own taxability rules in most states. Those rules frequently do not match the same state's SaaS rules. - **Information and data processing services**: States can take a while to catch up to technology. Some states never wrote a SaaS rule at all. They tax your product by fitting it into an older category. New Jersey taxes SaaS only when it qualifies as an information service, such as a database subscription. Texas treats SaaS as a data processing service and taxes 80% of the transaction. It’s important to note that selling mixed products complicates tax treatment. If you sell a hosted platform, plus an installed desktop client, plus implementation consulting, a state may tax each piece differently. Some states will tax the entire bundle at the highest applicable treatment if your invoice does not break out the components separately. ### How States Classify SaaS for Tax Purposes States don’t agree on how to tax SaaS products. About half the states either have taken no position or concluded that SaaS isn’t taxable. Though the states have taken no stand change from time to time. As recently as January 1, 2025, [Louisiana ruled that digital products, including SaaS, are subject to sales tax](https://revenue.louisiana.gov/tax-education-and-faqs/faqs/sales-tax-reform/are-digital-products-subject-to-sales-and-use-tax/). The ones who do consider SaaS taxable take different approaches. Some consider SaaS transactions taxable just like any other transaction. Others consider SaaS taxable if the sale directly translates to a tangible item (like an e-book), or if there is a downloadable component to the transaction. A handful of states, like Iowa and Ohio, only consider SaaS taxable if sold for either business or consumer use. (The bad news there is that states don’t agree which use should be taxable). And some tax SaaS at a reduced rate or only partially taxed, like Texas’s confusing “data processing services” tax, which has been ruled to apply to SaaS. (See table below.) ### SaaS Sales Tax by State – Where It’s Taxable and Where It’s Exempt Here’s a list of how states currently tax SaaS products. State Sales Tax on B2C SaaS?

Fortunately, Sphere is here to help with automated, AI-enabled sales tax management. ## Understanding Nexus Requirements for SaaS Businesses ### What Is Nexus? Nexus is Latin for “to bind or connect.” A company with sales tax nexus in a state has a close enough tie to that state that the state is justified in requiring your business to collect sales tax. Business activities that create nexus vary by state, but are generally: - **Physical presence**\- you have an office, home office, store, warehouse, employee, contractor or other physical connection to the state - **Inventory** – storing inventory in a state, even if you use a 3rd party to manage that inventory - **Click-thru nexus** - Using 3rd party affiliates in a state to send customers to your business - **Temporary nexus** - Occasionally doing business in a state, such as selling SaaS products at a tradeshow - **Economic nexus** - you exceed a certain amount of sales or transactions from buyers in a state The concepts of physical and economic nexus tend to trip SaaS stakeholders up, especially when Nevada comes calling for sales tax and you had no idea you even had an obligation to collect. Let’s take a look at the difference. ### Physical Nexus vs. Economic Nexus Physical nexus is fairly easy to comprehend. You live or do business in a state, you need to comply with the tax laws of that state. Economic nexus is a little trickier. Due to the 2018 _South Dakota v. Wayfair_ Supreme Court decision, states are allowed to require business–generally online businesses–that exceed a certain sales or transactions threshold to collect sales tax from buyers in the state. The threshold is usually $100,000 in sales or 200 transactions, though they–say it with me–vary by state. Why online businesses? Every state with a sales tax now has economic nexus requirements. These laws were originally designed to stop e-commerce giants like Amazon and the titular Wayfair from making large numbers of sales to buyers in a state without also paying their toll to the state’s coffers. To states, this closed a loophole where a business with no physical presence in the state could get away with selling “tax free.” ### How SaaS Companies Should Prepare As a SaaS business, it's vital to know which business activities create nexus and where you are exposed. The location of your employees, contractors, servers, and even your customers can determine whether you have an obligation to collect and remit sales tax. ## Steps to Ensure SaaS Sales Tax Compliance Did you know sales tax debt doesn’t discharge with bankruptcy? Be prepared by doing the following: 1. **Know your nexus exposure** – Where do you have nexus and how long have you had nexus in those states? 2. **Register for a sales tax permit in your nexus states** - it’s unlawful to begin collecting sales tax without registration 3. **Set up sales tax collection** – if you use more than one digital payment solution, make sure you set up sales tax collection on all of them. 4. **Automate sales tax filing and remittance** – States will require you to file and remit sales tax monthly, quarterly or annually. Automate so you can stay on task. ## Consequences of Not Collecting Sales Tax If you don’t collect sales tax in a state where you have nexus, you still owe the tax. The state bills your business for uncollected tax, cutting into your bottom line. Consequences include: - **Owning back taxes from prior periods:** The state will bill you uncollected sales tax from your date of first nexus in the state, which could be months or years. - **Penalties and interest:** On top of uncollected tax will be percentage-based penalties and interest, which are often as much as 25% of sales tax owed. - **Open-ended lookback period:** If you never registered, states can generally look back unlimited years to determine back sales tax liability. - **Audit risk:** Unusual activity, such as a new registration in a state with a high volume of activity, or appearing in a report from another audited company, can flag you for an audit. - **Risk to valuation and acquisition:** Investors and buyers look for sales tax liability in due diligence. If you have a big bill looming, your business may not look like a prime target for investment or acquisition. - **Personal liability:** Many states hold officers and other responsible persons personally liable for uncollected trust fund taxes like sales tax. Sales tax debt does not get discharged in bankruptcy. ## What to Do If You Haven't Collected Sales Tax in a State This is incredibly common. During the manic time of starting up a new business, dreaded sales tax compliance can fall by the wayside. Unfortunately, states also aren’t especially forgiving when it comes to the “I didn’t know I had to!” defense. If you’re reading this right now with a sinking feeling, you have options. This includes a “voluntary disclosure agreement” (VDA) where a sales tax expert helps you anonymously come clean to the state and negotiate your liability. Even if you’re just getting started or if you’ve been in business without collecting sales tax for years, it’s vital to get sales tax straight right now. #### Choosing the Right Option for Your Business Sales tax is nitpicky, time-consuming and involves collating large amounts of data. Which makes it the perfect task for AI automation. ### How to Automate SaaS Sales Tax Compliance #### Benefits of Automation There are more than 14,000 sales tax jurisdictions in the United States, each with their own rate.
