Is SaaS Taxable in Kentucky? Kentucky Sales Tax Rules for Prewritten Software and SaaS
In Kentucky, SaaS and prewritten computer software access services are subject to sales tax. Kentucky treats prewritten computer software as tangible personal property, whether delivered by download or another method. Access to prewritten software while the seller or a third party maintains possession of the software application is also taxable as a software as a service (SaaS) transaction.

Kentucky SaaS Sales Tax: SaaS Access Services Are Taxable
Kentucky applies sales tax to both prewritten computer software and prewritten computer software access services.
Kentucky treats prewritten computer software as tangible personal property (TPP), meaning software can be taxable even when delivered electronically.
Kentucky also specifically taxes SaaS transactions where customers access software while the software application remains in the possession of the seller or a third party.
Prewritten Software Is Taxable
Kentucky includes prewritten computer software in the definition of tangible personal property under KRS 139.010(46).
Example:
Prewritten software license USD 1,000
The software is taxable when sold as part of a retail transaction.
This applies whether software is:
- downloaded;
- electronically delivered;
- otherwise received by the purchaser.
Electronically Delivered Software Is Also Taxable
Kentucky does not treat electronic delivery as an automatic exemption.
Example:
Software download USD 500
Customer receives:
- downloadable software;
- no physical media.
The transaction remains taxable because it involves prewritten computer software.
SaaS Is Taxable as Software Access Service
Kentucky specifically defines taxable software access services.
A transaction is taxable when:
- the customer receives access to use prewritten software;
- possession of the software application remains with the seller or a third party.
Example:
Cloud accounting software subscription USD 300/month
Customer receives:
- online access;
- software functionality.
The provider maintains possession of the software.
This transaction is taxable as SaaS.
AI Software Is Also Covered
Kentucky specifically notes that prewritten computer software remains taxable even when it includes Artificial Intelligence (AI) components.
Example:
AI-powered software subscription USD 500/month
If the product qualifies as prewritten software access service, it remains subject to Kentucky sales tax.
SaaS vs. Traditional Software Sales
Kentucky covers both:
| Transaction Type | Example | Tax Treatment |
|---|---|---|
| Prewritten software sale | Downloaded software license | Taxable |
| SaaS access service | Cloud software subscription | Taxable |
The difference is ownership versus access, but both categories may be taxable in Kentucky.
Common Kentucky SaaS Compliance Issues
Assuming cloud software is exempt
Kentucky specifically taxes SaaS access services.
Assuming electronic delivery is exempt
Prewritten software remains taxable regardless of delivery method.
Failing to identify SaaS transactions
Businesses should determine whether customers receive ownership or only access rights.
Incorrect billing configuration
Subscription, access, and license fees should be properly classified.
Compliance Tips for SaaS Businesses
Businesses selling SaaS or software products to Kentucky customers should:
- Determine whether software qualifies as prewritten software;
- Identify taxable software access services;
- Apply Kentucky sales tax correctly;
- Maintain contracts and transaction records;
- Configure billing systems appropriately.
Conclusion
Kentucky clearly taxes:
- prewritten computer software;
- electronically delivered software;
- prewritten software access services;
- SaaS transactions.
For SaaS businesses, the key question is whether customers are accessing prewritten software while the software remains controlled by the provider.
