States That Tax SaaS (2026): Verified List + Nexus Thresholds

Updated

Reviewed by Nexus by State research team using official state tax sources. Last reviewed .

Which US states apply sales tax to SaaS subscriptions, with each state rate and economic nexus threshold side by side. Crossing the threshold means registering even where SaaS is exempt.

Whether a SaaS subscription is taxable depends on how the destination state defines prewritten software — not on where your company is based. As of 2026-08-02 this page lists the 15 states Nexus by State has verified as taxing qualifying SaaS subscriptions, with each state's rate and economic nexus threshold alongside. Taxability and nexus are separate tests: cross a state's threshold on subscription revenue and you must register and file there even if SaaS itself is exempt in that state.

SaaS taxability is the least settled corner of US sales tax, because most state statutes predate cloud software and were written around "tangible personal property". States that reached SaaS did so by different routes — some redefined prewritten software to include remote access, some tax it as a data-processing or communications service, some tax business use only. That is why the answer changes state by state, and why the rows below pair each state's rate with its economic nexus threshold: the threshold is what actually decides whether you have to register, and it applies whether or not your product is taxable there.

A state missing from this list is not a ruling that SaaS is exempt there. Several states tax SaaS under narrower rules — business use only, a reduced rate, or a separate digital-products regime — and are held off this list until an official state source can be cited for each. Treat the list as a floor, and check the state page and its Department of Revenue link before you decide not to collect.

Frequently asked questions

Is SaaS taxable in every state?

No. There is no federal rule and no shared definition, so the answer is set state by state and turns on whether the state treats remotely accessed prewritten software as taxable. Fifteen states are listed above as verified taxable as of 2026-08-02. In the rest, either the state has published no position, or it treats access-only SaaS as a non-taxable service because nothing tangible changes hands. That second group is the one to watch: several of those states have moved in the last three years, and the move is usually a statutory redefinition rather than a new tax.

Do I have to register for sales tax in a state where SaaS is not taxable?

Usually yes, once you cross that state's economic nexus threshold. Nexus is measured on gross sales into the state, not on taxable sales, in most states — so subscription revenue counts toward the threshold even where the subscription itself is exempt. The practical outcome is a registration, a periodic return, and a line reporting zero taxable sales. Skipping the registration because "we do not owe anything" is what turns a zero-dollar filing obligation into a penalty exposure.

What is the difference between SaaS taxability and sales tax nexus?

They are two independent questions that get collapsed into one. Nexus asks whether a state has the right to make you collect at all — answered by physical presence or by crossing an economic nexus threshold such as $100,000 in sales. Taxability asks whether the specific thing you sell is subject to tax once you are registered there. You can have nexus and owe nothing (SaaS exempt in that state), or sell a taxable product with no nexus and owe nothing yet. Both have to be true before you charge a customer.

How many states tax SaaS?

Fifteen are verified on this page as of 2026-08-02, and the true count is higher — SaaS taxability is one of the fastest-moving areas of US sales tax, and several states have added it through statutory redefinition since 2023. Any published count, including this one, is a snapshot. That is why each row here links to the state page and its Department of Revenue source rather than asking you to trust a number.

Does economic nexus count SaaS subscription revenue toward the threshold?

In most states, yes — the threshold is measured on gross or retail sales delivered into the state, which includes subscription revenue regardless of whether that revenue is taxable. A handful of states measure only taxable sales, which can leave a SaaS seller below the threshold in a state that exempts SaaS. Because the measurement rule differs, check the state page for the exact base before concluding you are under the line.

Is SaaS taxable where the customer is or where my company is?

Where the customer uses it. US sales tax is destination-based for remote sales in nearly every state, so a seller headquartered in a state that exempts SaaS still collects for customers located in states that tax it. For SaaS specifically the sourcing question can get harder when a single subscription is used by employees in several states — a number of states allow the charge to be apportioned across the users' locations, usually only with documentation supporting the split.
