Iowa Admin. Code r. 701-18.23
Purchase of food, drugs, medicines, bandages, dressings, serums, tonics, and the like, but not to include tools and equipment, which are used in treating livestock raised as part of agricultural production is exempt from tax. Where these same items are used in treating animals maintained as pets for hobby purposes, sales tax is due. See rule 701-1848. (422,423) for an exemption for machinery used in livestock or dairy production which may be applicable to veterinarians but should be claimed only with caution by them.
A veterinarian engaged in retail sales, in addition to furnishing professional services, must account for sales tax on the gross receipts from such sales.
This rule is intended to implement Iowa Code sections 422.42(3) and 422.43.
