Many manufacturers and utilities routinely acquire large quantities of tangible personal property under circumstances that make it impractical to determine, at the time of purchase, the manner in which property will be used. It is impractical in these circumstances to determine whether the purchase or use of the property will be taxable or exempt. Holders of direct payment permits are authorized to purchase most items of tangible personal property without payment of the tax to their vendors, and may instead report and pay tax directly to the State.
