If you run a software business, here’s a question that catches a lot of founders off guard: do you owe sales tax on your SaaS subscriptions? For years the answer was “probably not.” Today, after the 2018 South Dakota v. Wayfair Supreme Court decision, roughly half of US states tax SaaS in some form — and you can owe tax in states where you’ve never set foot.
This guide breaks down where SaaS is taxable in 2026, how economic nexus works, and the practical steps to stay compliant without losing your weekends to spreadsheets.
Is SaaS taxable in the US?
Sometimes. There is no federal sales tax and no national rule for software — each state decides for itself. As of 2026, around 24–25 states (plus Washington, D.C.) tax SaaS in some form, while the rest treat it as a non-taxable service. A handful of states only tax software when it’s downloaded rather than accessed in the cloud, and five states (Alaska, Delaware, Montana, New Hampshire, and Oregon) have no statewide sales tax at all.
The catch: the same monthly subscription can be taxable for a customer in New York and completely exempt for a customer in California.
How states classify SaaS for tax
Most states fall into one of three buckets:
- Taxable — the state treats SaaS like prewritten software or a digital product (for example, New York and Texas).
- Non-taxable — the state views SaaS as an intangible service, like consulting (for example, California and Florida).
- Conditional — taxability depends on how the software is delivered, whether the buyer is a business or a consumer, or what’s bundled with it (for example, Ohio and Iowa).
SaaS sales tax by state (2026 snapshot)
The table below shows how some of the most common states treat SaaS. Rules and rates change often, so always confirm with the state’s Department of Revenue before you rely on it.
| State | SaaS taxable? | Notes |
|---|---|---|
| New York | Taxable | Treated as prewritten software. |
| Texas | Taxable (80%) | Taxed as a data-processing service — 80% of the charge is taxable. |
| Washington | Taxable | Treated as a digital product; B&O tax also applies. |
| Pennsylvania | Taxable | Taxed as tangible personal property. |
| Massachusetts | Taxable | Remotely accessed software is taxable. |
| Connecticut | Taxable* | Reduced 1% rate for business use; full rate for personal use. |
| Ohio | Conditional | Taxable for business use; exempt for personal use. |
| Iowa | Conditional | Taxable for consumers; exempt for qualifying businesses. |
| Illinois | Chicago only | Exempt statewide, but Chicago applies a lease-transaction tax. |
| California | Not taxable | Exempt unless software is downloaded or delivered on media. |
| Florida | Not taxable | Treated as a non-taxable service. |
| Virginia | Not taxable | Exempt when nothing is downloaded. |
| Georgia | Not taxable | SaaS and hosting not taxed. |
| New Jersey | Not taxable | Considered a non-taxable service. |
| Delaware, Montana, New Hampshire, Oregon | No sales tax | No statewide sales tax at all. |

Economic nexus: the trigger most SaaS founders miss
You only collect sales tax in states where you have nexus — a tax connection. There are two kinds:
- Physical nexus — an office, inventory, servers, or even a single remote employee in a state.
- Economic nexus — crossing a sales or transaction threshold in a state, even with no physical presence.
Most states set economic nexus at $100,000 in annual sales or 200 transactions, though larger states like California, Texas, and New York use a $500,000 threshold, and many states have dropped the 200-transaction test entirely. Because SaaS often has low prices and high transaction counts, even small startups can trip these thresholds faster than they expect.
5 steps to stay compliant
- Track where you have nexus. Monitor sales and transactions by state so you know when you cross a threshold.
- Register before you collect. Get a sales tax permit in each state where you have nexus — charging tax without registering is illegal in most states.
- Charge the right rate. Rates vary by state, county, and city, and taxability can differ for business vs. consumer sales.
- File and remit on schedule. Each state assigns a filing frequency (monthly, quarterly, or annually) — missing one triggers penalties.
- Keep exemption certificates. If you sell to resellers or exempt organizations, collect and store valid certificates to defend yourself in an audit.
Common SaaS sales tax mistakes
- Assuming SaaS is never taxable because “it’s a service.”
- Ignoring a remote employee who quietly created physical nexus in a new state.
- Overlooking home-rule cities — Illinois exempts SaaS, but Chicago taxes it.
- Bundling implementation or support with the subscription without itemizing, which can make the whole invoice taxable.
- Waiting until an audit notice arrives instead of using a Voluntary Disclosure Agreement to clean up past exposure.

Frequently asked questions
Is SaaS taxable in all 50 states?
No. As of 2026, roughly 24–25 states plus Washington, D.C. tax SaaS in some form. The rest treat it as a non-taxable service, and five states have no sales tax at all.
Do I owe sales tax in a state where I have no office?
Possibly. Since Wayfair (2018), crossing a state’s economic nexus threshold — often $100,000 in sales or 200 transactions — can obligate you to collect tax there even with no physical presence.
Is SaaS taxable in California, Texas, or New York?
California generally does not tax SaaS (unless it’s downloaded). Texas taxes 80% of the charge as a data-processing service. New York taxes SaaS as prewritten software.
What happens if I haven’t been collecting sales tax?
You may owe back taxes, penalties, and interest. A Voluntary Disclosure Agreement (VDA) often lets you limit the look-back period and reduce penalties — a good time to talk to an accountant.
