Kentucky SaaS Sales Tax Guide & Taxability (2026)

SaaS taxability varies wildly by state. Kentucky's general sales tax rate is 6.00%, but whether software-as-a-service is subject to that rate depends on the state's definition of “taxable service” or “canned software” and on whether it's delivered to an in-state user.

Regardless of SaaS taxability, the economic nexus threshold of $100,000 or 200 transactions applies. If you exceed it on subscription revenue, you register; from there the question becomes what you tax, not whether.

1. Track Kentucky-sourced ARR (use billing country or IP geolocation).
2. Determine taxability: consult a CPA or use an automated service that maintains taxability rules by state.
3. Register once you cross threshold, even if SaaS is currently non-taxable — rules change.
4. Integrate tax calculation into your billing platform (Stripe Tax, Quaderno, Chargebee with Avalara).

• Treating SaaS and “canned software” the same way. Many states distinguish between cloud-hosted SaaS and prepackaged downloaded software, with different tax treatments. Check Kentucky's specific definitions before assuming your product falls in either bucket.
• Bundling non-taxable SaaS with taxable services (training, consulting, hosting). Bundle-pricing can make the whole charge taxable if the taxable component isn't separately stated.
• Ignoring use-tax obligations. If your customers are in Kentucky and your SaaS isn't taxable there, the customer may still owe use tax — a detail that can trip up B2B SaaS during audits.

Kentucky sales tax nexus and economic nexus threshold: through July 31, 2026, a remote retailer must register and collect Kentucky sales tax once it has $100,000 or more in gross receipts from sales into Kentucky OR 200 or more separate sales into Kentucky in the previous or current calendar year — meeting either test triggers the requirement (Kentucky Department of Revenue Wayfair guidance, HB 487; collections required beginning October 1, 2018). Effective August 1, 2026, House Bill 757 (2026 Regular Session, enacted over the Governor's veto) removes the 200-transaction test for both remote retailers and marketplace providers, leaving a $100,000 sales-only threshold that counts tangible personal property, digital property, and services delivered, transferred electronically, or provided to a Kentucky purchaser; sellers registered solely because of transaction volume should review whether they can deregister under Kentucky's trailing-nexus rules. Kentucky's marketplace facilitator law (HB 354) has been effective since July 1, 2019 — Amazon, Etsy, eBay, and Walmart collect and remit Kentucky sales tax on facilitated sales, registering once for all third-party sellers per KRS 139.450 (procedure clarified by HB 249, effective July 1, 2021). Kentucky levies a flat 6% statewide sales tax with no local sales taxes, so the rate is identical at every Kentucky delivery address. HB 757 also extends Kentucky sales and use tax to data brokering services beginning August 1, 2026. Direct-to-consumer sales outside any marketplace remain the seller's own collection responsibility once nexus is met.
