Is SaaS subject to sales tax?

It depends on the state where your customer uses the software. Some states tax SaaS as prewritten software, some tax it as a data processing or digital automated service, and others do not tax it at all.

Sales tax law was written for tangible goods. Software on a disk fit that model; software running on your servers and accessed through a browser does not. Each state has answered the question through its own statute, regulations and rulings, so the same subscription can be taxable in Austin, exempt in San Francisco and taxable at a reduced rate somewhere else.

Two other variables matter. First, some states tax SaaS only when sold to consumers or only when sold to businesses. Second, bundles matter: a subscription that includes implementation, training or a hardware device can be taxed differently from the software alone.

How the largest SaaS markets treat it in 2026

The table below covers the states we were able to confirm against the state's own guidance in October 2026. For every other state, check the revenue department's current software guidance before you decide.

StateSaaS treatmentNote
New YorkTaxableRemote access to prewritten software is a taxable sale
TexasTaxableData processing service; 20% of the charge is exempt
WashingtonTaxableDigital automated services; IT and custom software added Oct 1, 2025
CaliforniaNot taxable until Jan 1, 2027SB 122 makes SaaS and prewritten digital software taxable from 2027

New York. The Department of Taxation and Finance says prewritten software is taxable whether delivered on physical media, electronically or by remote access. A sale is sourced to where the purchaser uses or directs the use of the software, and when users sit in several states you collect New York tax on the portion of the receipt attributable to New York users.

Texas. Texas taxes SaaS as a data processing service and exempts 20% of the charge, so tax applies to 80% of the price at the combined state (6.25%) and local rate.

California. Under CDTFA Regulation 1502, prewritten software delivered electronically is not taxable when the buyer receives no tangible copy, and pure SaaS generally sits outside the sales tax. Watch for bundles with taxable hardware or tangible deliverables.

Washington's October 2025 change

Washington already taxed digital automated services and remote access software under its digital products rules. ESSB 5814 widened the base from October 1, 2025: information technology services (including technical support, help desk, data processing and implementation), custom website development, custom software and customization of prewritten software are now subject to retail sales tax and are reported under the retailing B&O classification.

For a SaaS company, this matters most for implementation and onboarding fees. If you sell a subscription plus a setup package to a Washington customer, both are now likely taxable, and the tax rate follows the location where the customer receives the service.

Other states: taxable, partly taxable or exempt

Beyond the four states above, treatment varies widely and changes often. Based on our reading of state guidance as of October 2026 (confirm before relying on it):

  • States that generally tax SaaS include Pennsylvania, Massachusetts, Tennessee, Utah and Connecticut (Connecticut at a reduced rate for computer and data processing services).
  • Some states tax SaaS only in certain uses. Ohio taxes it as automatic data processing when used in business, and Iowa taxes it but exempts sales to commercial enterprises for exclusive business use.
  • Many states do not tax SaaS at the state level, but local rules can still apply. Chicago's personal property lease transaction tax reaches cloud software even though Illinois does not tax SaaS, and some Colorado home-rule cities and Arizona cities apply their own rules.
  • Maryland taxes many digital products and added a separate tax on certain data and IT services in 2025, so Maryland customers deserve a specific review.

The direction of travel is toward taxing more digital services, as Washington and Maryland show. Review your taxability map at least once a year.

When you have to start collecting

You only collect in a state where you have nexus and the product is taxable. Nexus comes from physical presence (employees, offices, inventory) or from economic nexus, which in most states is triggered by sales into the state above a dollar threshold, commonly $100,000.

A useful order of operations: identify the states where you have nexus, then check whether your product is taxable in each of them. A SaaS company with $2 million of revenue spread across 40 states may only have nexus in a handful, and only some of those will tax the product. See our economic nexus guide for the thresholds we confirmed.

A practical compliance plan for SaaS companies

  1. Describe the product precisely: browser-only access, downloadable components, APIs, data services, bundled hardware, and any implementation or training fees billed separately.
  2. Build a state taxability matrix for every state where you have or expect nexus, citing the statute, regulation or ruling behind each conclusion.
  3. Where a state's rule is unclear for your product, ask for written guidance (many states issue letter rulings or advisory opinions). It protects you if the state later changes its view.
  4. Set product-level tax codes in your billing system or sales tax software so taxable subscriptions collect tax and exempt items do not. Separately state taxable and nontaxable charges on invoices.
  5. Collect exemption and resale certificates from customers who claim them, and keep them with the invoice records.

We usually tell seed-stage SaaS teams to do this exercise before the first state registration, not after the first audit notice. This is general guidance, not tax advice for your specific facts; product details change the answer.

Frequently asked questions

Which states tax SaaS?

Treatment changes often, but New York, Texas, Washington and Pennsylvania are among the states that tax SaaS, and several others tax it in some uses. California generally does not tax SaaS before January 1, 2027, when SB 122 adds SaaS and other digital products to the sales tax base when the customer receives no tangible copy. Because rules differ in how they define software and services, confirm each state where you have nexus against the revenue department's current guidance before you start or stop collecting.

Is SaaS taxable in California?

Generally no. California sales tax applies to tangible personal property, and CDTFA Regulation 1502 treats prewritten software delivered electronically, with no tangible copy to the buyer, as nontaxable. Pure SaaS accessed over the internet usually falls outside the tax. Bundles that include hardware or tangible deliverables can change the result, so review how your invoices are structured.

How does Texas tax SaaS?

Texas treats SaaS as a data processing service. Twenty percent of the charge is exempt, so tax applies to 80% of the price at the combined state rate of 6.25% plus any local rate. A $10,000 annual subscription sold to a customer in a location with a 2% local rate would carry tax on $8,000, or $660.

Do I charge New York sales tax if only some users are in New York?

Yes, on the New York share. New York sources remote access software to where the purchaser uses or directs the use of the software. If a customer has users both inside and outside the state, you collect New York tax on the portion of the receipt attributable to New York users, so keep a reasonable record of user locations.
