KRS Chapter 139 is the principal statutory starting point for Kentucky sales and use tax. Controversies may involve nexus, taxable receipts, exemptions, resale, marketplace transactions, audits, unfiled returns, or tax collected but not remitted.
What the authority does
The chapter defines core terms, imposes sales and use taxes, addresses seller collection and purchaser liability, provides exemptions and exclusions, and governs returns and related administration. Regulations and Department guidance supply further detail.
Why it matters in a tax controversy
An audit defense should reconstruct transactions by period and category, identify exemption certificates and resale documentation, reconcile returns to books and bank records, and test the sampling or estimation method used. Collected-but-unremitted tax presents a different risk profile from an exemption-classification dispute.
What it does not answer by itself
A general exemption label is not proof that a transaction qualifies. Entity status, purchaser use, item or service classification, documentation, effective dates, and local facts can determine the result.
Research and case checkpoints
- Identify the transaction type, parties, location, and applicable period.
- Separate tax collected from tax the Department says should have been collected.
- Gather exemption certificates, invoices, resale records, and accounting detail.
- Review KRS 131 procedure for assessment and protest deadlines.
