Yes, you are being VERY argumentative. Sales tax is a small application compared to some of the stuff that can be done on a desktop computer or a laptop. Heck, this being a photographic website, doing image post-processing on a pictures requires far more computing power than calculating sales taxes.

As I have said several times now, there are services that do that for you and I'll bet you there will be a bunch of other providers for this simple service that will cost very little on a per-transaction basis. Accepting credit cards is almost ubiquitous now at places and by people that would never have done it just a few years ago.

For example, for the last couple of years local swim teams have events where they serve food like hot dogs, hamburgers and bottled water and such and they take credit cards which they zip through a little adapter on a smartphone. It's pennies per transaction.

On a small business's website, the shopping basket and credit card is all a service provided by a third-party that charges a small percentage for each transaction. The sales tax thing will just be an additional services provided the same way, probably by the same people.

This doesn't require gigantic computers with vast amounts of storage. This is a no-brainer, just another opportunity to offer a service and suck money from the consumer to feed the forever hungry governments.

I suspect you don't know much about computers.

Here is a link to the service/software I mentioned a few times already:

I'm sure there are others and like everything else in the world if there's a need for it, services will appear. Who would have thought you could accept credit cards using a smartphone and a simple little plug-in reader? In this connected world of ours, there should be or will be "an app for that" to calculate the proper sales tax and even deal with the remittance to the proper locations.
