Is SaaS Taxable in Kansas? No, but Downloaded Software Is, and the Line Is Where the Code Runs

Key Takeaway: Kansas does not tax SaaS. The retailers' sales tax reaches tangible personal property and a closed list of services, and the Department of Revenue says remote access to someone else's software is neither. Prewritten software, though, is tangible personal property in Kansas and is taxed "whether it is delivered to the customer electronically, on a physical medium, or by 'load and leave.'" For an AI agent business, the question in Kansas is where the code runs. If it stays on your servers, the charge is not taxed. If it lands on the customer's machine, it usually is.

What I Read

This guide rests on the Kansas Revisor of Statutes' current text of K.S.A. 79-3603 (the imposition section), K.S.A. 79-3602 (definitions, including (cc) and (pp)) and K.S.A. 79-3702 (compensating use tax definitions, including the remote-seller test at (h)). It also rests on the Department of Revenue's publication EDU-71R, Revised Sales Tax Guidelines: Taxing Charges for Computer Products and Services and Internet Related Sales and Services, issued July 23, 2010, read in full.

EDU-71R is sixteen years old and cites the 2009 statute supplement, but the software provisions of the current statute read the way it describes them, and I found no later publication that replaces it, nor any 2026 bill or ruling on SaaS or AI. It says Department guidelines "are not legal rulings," so treat it as the Department's position, not a safe harbor.

SaaS: Not a Sale and Not a Listed Service

K.S.A. 79-3603 levies a 6.5% tax on "the business of selling tangible personal property at retail in this state or rendering or furnishing any of the services taxable under this act." The rest of the section is a closed list running from (a) to (x): among other things telecommunications, utilities, meals, admissions, hotel rooms, rentals of tangible property, dry cleaning, installation and repair, subscriber radio and television, prewritten software, telephone answering and prepaid calling. Software access is not on it. As EDU-71R puts it in another context, "Only services enumerated in the act are subject to tax."

That leaves two routes by which SaaS could be taxed: as a lease of tangible property under 79-3603(h), or as a sale of prewritten software under 79-3603(s). EDU-71R closes both.

• Not a lease. §IV(e): "A lease does not include obtaining remote access to someone else's computer software and equipment via the Internet or other electronic means when the customer does not have control over or have possessory rights to the software or equipment. This includes charges billed by an application service provider (ASP)."

• Not a software sale. Section IV(h), on web hosting: "As a general rule, for an electronic transaction to be taxable as the sale of prewritten software, the software must at least temporarily reside in the customer's computer."

A per-call API, a hosted agent and a chat interface all fit the ASP description. None of them is taxed.

Downloads Are Taxed

The other side of the line is the one that catches AI businesses. K.S.A. 79-3602(pp) says tangible personal property "includes electricity, water, gas, steam and prewritten computer software." K.S.A. 79-3603(s) then taxes the sale of prewritten computer software "whether the prewritten computer software is installed or delivered electronically by tangible storage media physically transferred to the purchaser or by load and leave," and the sale of services "modifying, altering, updating or maintaining" it.

So these are taxable at 6.5% plus local tax:

• A desktop or mobile app the customer installs.

• A command-line tool, plug-in or locally run agent the customer downloads. EDU-71R adds that "the sale of a license to use prewritten software for a limited period is taxed the same as the outright sale," so an annual license to a downloaded tool is taxed too.

• Licenses for prewritten software "located in a computer or server in Kansas owned by or leased to the software license purchaser" (EDU-71R §IV(c)(2)). Software the customer installs on its own Kansas server is taxed even though nobody downloads it to a laptop.

I have not resolved whether downloadable model weights are "prewritten computer software." Until Kansas says otherwise, I would treat a paid model download as software.

Custom Work and Maintenance Contracts

Custom software is not taxed. EDU-71R §I(a): software "designed and developed for the exclusive use and needs of a specific person or business" is custom, and "the providing of custom software is considered a non-taxable service." It becomes prewritten software if it is offered to anyone else. Customizing prewritten software is different. K.S.A. 79-3602(cc) says a modification made to one purchaser's specifications "remains prewritten computer software, except that where there is a reasonable, separately stated charge or an invoice or other statement of the price given to the purchaser for such modification." EDU-71R draws the consequence: if the vendor "elects to charge a lump sum," "the entire amount that is invoiced is subject to sales tax." Fine-tuning a packaged product for one customer belongs on its own invoice line.

Maintenance contracts depend on the facts. EDU-71R §III(d) sets out four rules:

• A mandatory maintenance agreement, one the customer must buy with the software, is fully taxable "even when charges for technical support and upgrades are separately-stated."

• An optional agreement that does not separately state support and upgrades is taxed on 50% of its price.

• An optional agreement that separately states them is taxed on the upgrades only.

• An optional support-only agreement is not taxable.

Maintenance for custom software is not taxable at all.

Data Processing, Information Services and Downloads of Content

Most AI work products land on the nontaxable side.

• Data processing. EDU-71R §IV(f): "A charge for the service of processing a customer's data is not subject to Kansas sales tax regardless of" how the output is delivered, whether it is billed by the minute or hour, or whether the customer supplied the programs. Batch inference over a customer's data fits its examples.

• Information services. EDU-71R §IV(d) treats "an 'information service' or 'database access service'" as "a nontaxable service," with research databases among its examples. A research agent that answers queries from its own data store is on the same footing. See our Kansas information services page.

• Digital content. EDU-71R §IV(c)(2): "Kansas generally does not tax electronic downloads of digital products," including movies, music, photographs and pictures, because "they are not tangible personal property." AI-generated images, audio and documents sold as downloads are not taxed. See our Kansas digital goods page.

• Web design and hosting. Neither is taxable unless the customer must download software or buy hardware (§IV(g), (h)).

One exception matters to anyone selling video: K.S.A. 79-3603(k) taxes "subscriber radio and television services," which EDU-71R applies to such services "delivered over the Internet."

The Kansas server trap. EDU-71R §IV(i) taxes the lease of a server, or space on one, located in Kansas, and software installed on it. An agent company renting hardware in a Kansas data center owes tax on the rent even though its customers owe nothing.

Remote Sellers and Buyers

Sellers. K.S.A. 79-3702(h)(1)(G) makes a remote retailer a "retailer doing business in this state" with "in excess of $100,000 of cumulative gross receipts from sales by the retailer to customers in this state" in the current or preceding calendar year. There is no transaction count. A SaaS-only seller has nothing taxable to collect; one that also sells downloads does.

Buyers. The compensating use tax follows the same line. K.S.A. 79-3702(c) defines "use" as exercising a right or power "over tangible personal property," and prewritten software is tangible personal property. A Kansas company that downloads software from a vendor that does not collect Kansas tax owes use tax on it. Its SaaS subscriptions are not tangible personal property and carry no use tax.

How AgentTax Handles Kansas

I ran the engine for a Kansas business buyer on a $1,000 purchase today, with Overland Park ZIP 66212 (9.35% combined).

• $0: saas, api_access, ai_model_access, ai_labor, compute, data_processing, storage, cloud_infrastructure, data_purchase, consulting, subscription, web_hosting, payment_processing_fee, and research and content work.

• 9.35% ($93.50): license, which is how to send a downloaded or installed software sale. In Wichita (67202) the same call is 7.5%.

• Software maintenance: with no contract facts, the engine taxes the full price, the mandatory-contract answer and the highest one the facts allow. Send maintenance_contract with mandatory: false and includes_upgrades: false for an optional support-only agreement and it returns $0.

Send software downloads as license, not digital_good. A digital_good follows the digital-products rule and returns $0 even with digital_content_type: "software": right for an e-book, wrong for an installer.

Without a ZIP, the engine uses the 6.5% state rate and warns that local tax (up to about 3% in our table) may apply. For sellers, the engine returns $0 with a NEXUS_NOT_CONFIGURED advisory until Kansas is set in your nexus configuration. To run the numbers, use the playground or the AI agent sales tax API. For other states, see the 50-state SaaS guide.

What to Watch

First, whether Kansas replaces EDU-71R. The Department's position on computer services rests on a 2010 publication, and a rewrite is where a change would show up first. Second, whether the legislature takes up digital products, as several states have. Until it does, the useful question for an agent seller is whether any part of the product runs on the customer's machine.
