Which states tax SaaS and which don't?
⚡ TL;DR
SaaS is taxable in roughly half of US states, including TX, NY, WA, CT, IN, MN, WI, PA, TN, and KY (which added SaaS to its taxable base effective January 1, 2023). CA, FL, AZ, CO, GA, IL, VA, and MA generally do not tax SaaS. Texas applies a 20% exemption, meaning only 80% of a SaaS charge is taxable — a frequently missed nuance.
SaaS taxability is one of the most state-variable questions in sales tax. The outcome depends on how each state has interpreted its existing tax statutes in the context of cloud-delivered software, and those interpretations differ significantly.

Why the line is blurry
Several states don’t have a definitive SaaS rule, they tax “computer software” or “data processing” or “information services,” and whether a given SaaS product fits within one of those categories depends on what the software actually does.
- Texas’s 20% exemption: TX taxes SaaS as a data processing service, but provides a 20% exemption, meaning only 80% of the SaaS charge is subject to tax. This is a frequently missed nuance.
- Pennsylvania’s computer services: PA taxes computer services broadly, which generally captures SaaS, but the exact scope depends on how the service is characterized.
- Illinois: IL generally doesn’t tax SaaS but does tax some data processing services. The line between the two can require a product-specific analysis.
What SaaS sellers need to do
- Identify the product tax code that correctly characterizes your SaaS product, many tax engines distinguish between hosted software, SaaS, data processing services, and information services
- Verify state-specific treatment in your top 10 revenue states; don’t rely on generic “digital products” codes
- Track legislative changes — Kentucky’s 2023 expansion is an example of a state that previously didn’t tax SaaS and then did; more states are considering similar expansions
- For Texas specifically, confirm your tax engine applies the 20% exemption to reduce the taxable base
Frequently asked questions
Is SaaS taxable?
SaaS is taxable in roughly half of US states and not taxable in the other half. There is no federal standard: each state has made its own determination based on whether SaaS fits within its existing taxable categories (software, computer services, data processing, or digital goods). Key states that tax SaaS: TX, NY, WA, CT, KY (expanded 2023), IN, MN, WI, PA (computer services), RI, SD, TN, VT, West Virginia. Key states that do not tax SaaS: CA, FL, AZ, CO, GA, IL (generally), OR (no sales tax), NH (no sales tax).
How did Kentucky change SaaS taxability in 2023?
Kentucky passed HB 8 in 2022, effective January 1, 2023, which explicitly added dozens of services to the taxable base, including SaaS, software-as-a-service, and other digital services. The expansion was significant because Kentucky had previously not taxed SaaS. SaaS companies selling into Kentucky needed to begin collecting as of January 1, 2023.
