Example 1. X, a resident of Ohio, visits a West Virginia furniture store and purchases furniture for $500. X makes payment, and the vendor delivers the goods to the purchaser in Ohio. Said sale is taxable for the consumers sales and service tax and the vendor must collect that tax in the amount of $30.00, unless the vendor can show (via a written sales contract, etc.) that the delivery was not incidental to the sale and was, in fact, indispensable and that the sale was consummated in Ohio.
Example 2. A resident of Virginia takes a toaster into West Virginia and has the same repaired by a serviceman. The person performing the service must collect the consumers sales and service tax. However, if the person performing the services goes to the purchaser's home in Virginia to repair the appliance, no such tax is applicable.
Example 3. A repairman travels to Virginia and takes possession of an appliance which he takes to his shop in West Virginia. After making the repairs at his place of business, the serviceman then delivers the appliance to the owner's residence in Virginia. The serviceman must charge and collect West Virginia consumers sales and service tax on his services, inasmuch as such services were performed within this State, unless delivery out-of-state was indispensable, not incidental to consummation of the service provided.
