SaaS Sales Tax by State (2026, With 2027 California and Colorado Changes)

Only 15 states and DC tax SaaS in a clean, statewide way. Another 6 states tax it with a twist, like a lower business rate or a partial base, so read the state row before assuming a flat answer.

These are state rates only, so your real bill can run higher once local and district taxes are added. The spread between Connecticut business use at 1% and personal use at 6.35% shows how much the buyer's purpose matters.

California expects about $900 million for its General Fund in 2027-28, the first full year, plus about $1.1 billion in local sales tax. Those are May Revision estimates made before SB 122 was final, and the LAO said the real figure could be hundreds of millions higher or lower.

Colorado's fiscal note projects software sales of $16.44 billion in FY 2026-27, and for its revenue estimate it assumes only 20% of downloadable software sales become taxable. The note itself warns the numbers are highly uncertain.

Is SaaS taxable in my state?

Start with the state where the software is used, not where the vendor is. Many states that tax SaaS follow the user. New York says local tax follows where users are, and Pennsylvania taxes canned software when the user is in Pennsylvania. A vendor based in Oregon, which has no general sales tax, can still have to collect Washington tax on seats used there once it sells enough into Washington.

Then look at how your state frames the product. Many state rules never use the word "SaaS." Texas calls it a data processing service. South Carolina treats it as a communications service. The District of Columbia lists application software under data processing. Arizona's Court of Appeals called a hosted software subscription a rental of tangible property. Different label, same result: tax.

In the states that don't tax it, small facts can flip the answer. Illinois and Michigan both say a downloaded agent or applet can make an otherwise exempt cloud product taxable. If your tool ships a desktop app alongside the browser version, ask the vendor how they classify it.

What changes in California and Colorado on January 1, 2027?

California's SB 122 adds digital products, including SaaS, to the sales tax base at the 7.25% statewide rate plus district taxes. Custom software and what the law calls digital infrastructure stay out, as do digital audio, video, books and games. Big buyers get a new wrinkle: once purchases from one retailer pass $5 million a year, liability may shift to the buyer, who may need a Use Tax Direct Payment Permit.

Colorado's HB26-1223 taxes software delivered by download or remote access, including mobile apps. The key exception is software under an individually negotiated license signed by both parties. A click-through or standard form agreement does not count. That means the way you paper the deal can change the tax. Local governments in Colorado can only adopt the new base with voter approval, so state tax comes first.

For a California or Colorado customer renewing an annual plan in late 2026, the timing matters. A plan billed upfront in December may land on the other side of the line from one that renews in February. Check your renewal date now, and if you are close to the line, ask the vendor in writing how they will bill the first 2027 invoice.

Sellers have their own homework. A small SaaS company with California or Colorado customers will need to register, collect and file once the change takes effect, and update its standard terms so the tax line is clearly separate from the subscription price.

How do Texas, Connecticut and Maryland tax SaaS differently?

Texas taxes SaaS as a data processing service and exempts 20% of the charge. The 6.25% state rate plus local tax applies only to the other 80%. If your vendor's invoice shows tax on the full subscription price, you are being taxed on money the state says is exempt, and that is worth a short email to their billing team.

Connecticut cuts the rate to 1% when a business buys the software for business use. The same tool bought for personal use is taxed at 6.35%. Maryland splits the same way: 3% for software used in an enterprise computer system since July 1, 2025, and 6% for individual use. In both states, telling the vendor how you use the product, in writing, is how you get the lower rate.

Iowa and Ohio draw the business line in opposite directions. Iowa exempts SaaS a commercial enterprise buys for its own exclusive use. Ohio taxes data processing, computer and electronic information services only when they are used in business, and whether a given SaaS product fits those labels depends on what it does.

Why do different sources count different numbers of states?

You will see different totals depending on who is counting. The California Department of Finance put the figure at 24 of 45 sales tax states in May 2026, before California and Colorado passed their changes. The same count found 35 states tax prewritten software delivered electronically, which is a different question from SaaS.

Our state table, checked as of October 17, 2026, puts 15 states and DC in the plain taxable group and 6 states in a partial group. Another 5 have no clear statewide rule at all. Alabama, Nebraska, North Dakota and West Virginia tax software in general terms but have not said how hosted access fits, and Wyoming has no published rule on it. In those states, vendors make their own call, and two competing tools can end up treating the same customer differently.

The practical point: don't rely on a single headline number. Look up the row for each state where you have users, and read the detail column. A state that says it taxes software "regardless of its function or form of transmission," as Alabama's rule does, may still be silent on whether a browser login counts.

Who pays the tax, the vendor or the customer?

In most states the buyer bears sales tax and the seller collects it. A few, like Arizona, Hawaii and New Mexico, levy their tax on the seller, who usually passes it on. Either way, the contract decides how it shows up. Many SaaS order forms say prices exclude taxes and the customer pays all of them. Some say the price is tax inclusive. A few say nothing at all, and that silence is where disputes start.

If a vendor fails to collect and a state audits you, you may owe use tax on the past bills anyway. That is why a clear tax clause protects both sides. Buyers want to know the tax is only what the law requires. Sellers want the right to add it if a state like California or Colorado changes the rules midway through a multi-year deal.

What freelancers, small sellers and buyers should do now

• List where your users or seats actually are. Multi-state teams can split tax across several states on one invoice.
• If you resell or white-label software, check whether your state taxes your bundle. Massachusetts, for example, does not tax remote software that is only incidental to a non-taxable service.
• Give your vendor an exemption or business-use statement where one applies, such as Connecticut, Maryland or Iowa.
• In Colorado, if you have users outside the state, ask about the written statement that lets you prorate license fees.
• Before you renew a California or Colorado contract, read the tax clause and the price-change clause together. A new tax should not also trigger a fee increase.
• Keep copies of invoices showing tax charged. If a vendor never charged tax in a taxable state, talk to your accountant about use tax.
