Yes, non-profit organizations receiving payments for the rental of space are liable for sales and use tax on those receipts. Although the sale of admissions for non-profit educational, charitable, or religious 501(c)(3) organizations is exempt under KRS 139.495 and the sale of admissions by non-profit civic, governmental, or other non-profit organizations is exempt under KRS 139.498, there is no corresponding exemption in HB 8 to exempt these non-profits from liability for sales tax on their receipts from these space rentals.
