(a) Tangible personal property used or consumed by the veterinarian.
(2) Tangible personal property that is administered by a veterinarian, or by an assistant under the veterinarian's direction, during the treatment of an animal is:
(3)
(b) Drugs requiring a prescription.
(1)
(i) The veterinarian must pay tax on its purchase of drugs that can only be legally dispensed by prescription.
(2)
(B) The sale of the drug is a retail sale of tangible personal property because the drug is not sold by a veterinarian pursuant to a veterinarian-client-patient relationship. Example: J.T. takes his cat to the veterinarian. The veterinarian diagnoses the cat with a heart condition and prescribes a beta blocker. The drug can only be legally dispensed by prescription. J.T. must refill the prescription on a monthly basis. J.T. refills the prescription for the beta blocker at his local pharmacy. The pharmacy should collect tax from J.T. on the retail sale of the beta blocker.
(2) If the invoice does not separately state taxable and nontaxable items, then the total amount reflected on the invoice may be subject to tax. Example: J.T. takes his dog to the veterinarian to examine a skin condition. The veterinarian determines that the dog has a bacterial infection and prescribes a drug to be administered twice a day for a week. The drug can only be legally dispensed by prescription. During the checkout, J.T. also purchases three (3) months of flea and tick preventative that can be purchased without a prescription. J.T. is charged for the office visit, the drug, and the flea and tick preventative, which are separately itemized on the invoice. The veterinarian should collect sales tax from J.T. on the retail sale of the flea and tick preventative.
