KEH had slightly better prices than
adorama or
B&H for the things I was looking for. It wasn't the biggest deal in the world, but it was kind of annoying to spend like 2.5 hours shopping on
KEH, then to just have to turn around and try to put together the same basket at a combo of
B&H and
Adorama.
In GA, B2B out of state purchases are required to pay taxes, but in state purchases by regular consumers aren't for most consumer items. This wouldn't be the IRS, because sales tax is a state tax, not a federal tax. The issue becomes which state the transaction is occurring in. Is it occurring in the state that the end buyer is located or the state where the seller is located? Traditionally the sale was said to have been completed upon delivery, and thus the location would be where the buyer was located. However, state tax agencies, with their tiny budgets had no real way to collect this tax. And in fact were discouraged to try in most cases, sense the enforcement was often ruled to be arbitrary and punitive. ie citizens had a legitimate complaint of 'why me?' if the state targeted them while letting thousands of others go free. Most courts will strike down arbitrary enforcement of laws that are 'technically on the books'.
The problems governments are running into is that while they could probably get away with changing the laws, they'd almost certainly have to collect them from the businesses, because requiring individuals to file these taxes is a NIGHTMARE and would cause outrage amongst the citizenry. But then you're to the problem of doing one of 2 things: either you A) charge your businesses located in your state for shipments going outside (essentially defining the sale as the place purchased) or B) charge taxes on businesses not in your state
A has issues because it would likely just run online retailers to states without sales tax, like Delaware and Tennessee. These businesses often provide a lot of jobs to the local economies, so you'd be kicking out employers who do pay lots of other forms of taxes in your state. B has issues with jurisdiction and free interstate commerce as required by the constitution. Because the businesses aren't located in the state attempting to collect, they have no legal recourse, and the constitution prohibits tariffs or barring the sale and shipment of items from other states, so the local governments can't enforce the taxation that way either. Its why there has been a lot of talk about enforcing sales tax on online purchases for a long time, but many legal scholars doubt that it will ever actually be put in place, or that if it is, that it will last very long.
If you went after the individuals, the first wave of prosecution of individuals for not paying online taxes would cause a wave of political pressure to do away with the laws entirely. If you go after the businesses, you'll either lose all your online retailers to other states or have your laws SCOTUS slapped down.
