Then, Amazon actually started doing business inside of these states in the form of affiliate programs and warehouses. It is on these two points that the fight is being contested When I was involved with on-line retail, the existence of a warehouse in a state constituted having a presence in the state. We had a warehouse in NJ that we shipped from, and that was the only state we had to collect sales tax for. We delayed opening another warehouse because of the sales tax implications, but finally opened up up in NV in order to reduce shipping time and cost to the west coast. We only had to collect sales tax for those two states (I know because I wrote the code for it). Now, from what I understand, Amazon tries to get around even that by having their warehouses owned/run by a subsidiary or other entity that is not strictly Amazon but ships Amazon's items to other states (not to the state itself, otherwise this sub-company would have to collect and pay sales tax). Strictly speaking, Amazon still doesn't have a presence in the state in terms of warehouses, so until the state laws are changed to recognize these shipping/warehousing-only companies as one and the same as Amazon, there's still no sales tax to collect on a pure existence-of-business-entity in the state in the form of a warehouse. Amazon effectively outsources their warehousing and shipping to other companies -- this is actually pretty common (along with drop-shipping) in the mailorder business because running a warehouse is an expensive, capital intensive operation. Affiliate programs are outsourced services also, outsourced marketing (lead generation). Really, this comes down to an attempt to tax outsourced operations. Maybe a better way for the states to fight it is to change the zoning and the tax laws so that warehouses are taxed more aggressively (especially if they ship things out of state -- warehouses that ship intrastate would have to collect sales tax, warehouses that ship interstate would pay higher business or property taxes). IANAL and IANA-Tax-Collector.
