Veterinarians must collect retail sales tax on certain sales of tangible personal property and remit the tax to the state along with their B&O taxes. The retail sales tax is a tax on the consumer or user of tangible personal property and retail services in Washington. Buyers are subject to and must pay the sales tax when making retail purchases, sellers must collect and pay the tax to the Department of Revenue. Sellers are liable for the tax even if they do not collect it from the buyer.
Sales tax rates - Combined state and local sales tax
The state retail sales tax rate is 6.5% and local rates vary from 0.5% to 3%, for a combined rate of 7.0% to over 10% in some areas. Retail sales tax is based on the "selling price" of an item, which includes delivery charges and any other costs whatsoever paid or accrued. An updated list of all local rates is available each quarter.
Which rate to charge?
The location of sale determines the applicable local sales tax rate. In the case of goods delivered to a client, the place where delivery occurs determines the location of the sale. Therefore, veterinarians should collect sales tax at the rate for their business location when the items are picked up by the customer. When items are delivered to the customer, the sales tax is collected based on the rate where the buyer receives or takes possession of the merchandise.

Itemize sales tax
Sales records and receipts or invoices for sales subject to retail sales tax must separately list the sales tax. It is not sufficient to merely state that tax is included. When tax is not listed separately, the law presumes that the gross amount of the receipt is subject to sales tax and tax will be assessed on that amount.
Itemize sales taxable/non-sales taxable charges
Veterinary customers frequently make retail purchases of medicines and the like in conjunction with receiving veterinary services. For example, a pet owner may purchase pet vitamins at the same time their pet receives its annual checkup. The sales invoice must clearly identify the charge for veterinary services, the charge for the vitamins, and the sales tax charged and collected on the price of the vitamins.
