SaaS Sales Tax by State for NYC Founders

Key Takeaways

• SaaS taxability varies wildly by state. Some tax it as a service, some as tangible personal property, some don’t tax it at all.
• Roughly 20+ states tax SaaS. The list changes every year. As of April 22, 2026, 24 U.S. sales-tax jurisdictions generally tax SaaS under current published guidance: 23 states plus Washington, D.C. TaxJar’s current state-by-state SaaS table lists these as taxable: Alabama, Alaska, Arizona, Connecticut, Hawaii, Iowa, Kentucky, Louisiana, Maryland, Massachusetts, New Mexico, New York, Ohio, Pennsylvania, Rhode Island, South Carolina, South Dakota, Tennessee, Texas, Utah, Vermont, Washington, West Virginia, and Washington, D.C. Connecticut taxes SaaS for personal use at the full rate but business use at 1%; Iowa taxes SaaS except when used for business purposes; Maryland taxes personal-use SaaS fully but taxes business-use SaaS at 3%; Ohio taxes SaaS for business use but not personal use; Texas treats SaaS as a data processing service, with 80% taxable / 20% exempt.
• New York generally treats SaaS as taxable by classifying it as access to prewritten computer software under New York tax law, even when delivered via the cloud. This means SaaS subscriptions are taxed as a software license rather than a nontaxable service. While some digital offerings may fall under information services, most SaaS is analyzed under the broader software rules. Custom software remains an exception and is generally not subject to sales tax.
• Economic nexus thresholds apply to SaaS sales the same as physical goods. Once you cross into a taxing state, you register and collect.

Why SaaS Sales Tax Is a Mess

Every state wrote its own rules. Some states tax SaaS as a service (taxable in states that tax services). Some treat it as tangible personal property (software = property). Some exempt it entirely. Some tax B2C but not B2B. Some tax it only if delivered in-state.

For an NYC SaaS founder with customers nationwide, that means reviewing every state where you have customers and figuring out:

1. Does this state tax SaaS?
2. If yes, under what category?
3. Are there exemptions (B2B, resale certificate, specific industries)?
4. What’s the economic nexus threshold?
5. Have I crossed it?

The Taxable States (Roughly)

As of April 22, 2026, 24 U.S. sales-tax jurisdictions generally tax SaaS under current published guidance: 23 states plus Washington, D.C. TaxJar’s current state-by-state SaaS table lists these as taxable: Alabama, Alaska, Arizona, Connecticut, Hawaii, Iowa, Kentucky, Louisiana, Maryland, Massachusetts, New Mexico, New York, Ohio, Pennsylvania, Rhode Island, South Carolina, South Dakota, Tennessee, Texas, Utah, Vermont, Washington, West Virginia, and Washington, D.C. Connecticut taxes SaaS for personal use at the full rate but business use at 1%; Iowa taxes SaaS except when used for business purposes; Maryland taxes personal-use SaaS fully but taxes business-use SaaS at 3%; Ohio taxes SaaS for business use but not personal use; Texas treats SaaS as a data processing service, with 80% taxable / 20% exempt.

The list changes. States expand SaaS taxability almost every year to catch up with revenue.

What to Do

Step 1: Build your state-by-state matrix

Pull your revenue by customer billing state for the last 12 months. Flag states with over $100K in SaaS revenue or 200+ subscriptions.

Step 2: Check taxability for each flagged state

For each flagged state, determine: taxable, partially taxable (B2C only), or exempt. SOURCE

Step 3: Register and collect where required

In states where SaaS is taxable and you’ve crossed the threshold, register for a sales tax permit, configure your billing system (Stripe Tax, Avalara, TaxJar) to collect the right rate, and remit.

Step 4: If you’re behind

Most SaaS founders are. Come to them before they come to you. Most states have voluntary disclosure programs. You come forward, they generally waive penalties, you pay the back tax plus interest, and you’re clean going forward.

It’s much more beneficial for a taxpayer to clean up their tax issues before they get a notice from a state. If you come to them before they come to you, the chances of getting penalties waived are much, much, much greater.

B2B Exemptions and Resale Certificates

In states that tax SaaS, B2B sales may be exempt or zero-rated if the customer provides a valid resale or exemption certificate. Collect and store these certificates. If you get audited, you need to produce them.
