I was reading an interesting point that here in BC they are scrapping this HST system that was introduced awhile ago and are now reverting back to an old tax system called the PST. This obviously requires a lot of businesses to update its system while registering for the tax as well. Apparently a large chunk of businesses have not done this yet. Therefore, for many consumers you may end up having to pay more taxes on an item simply because the business didn’t update the tax for its business yet.
I can imagine a lot of arguments between the business and consumers as a result of this. For the consumer I suppose this means you have to be more diligent in checking the receipt to make sure that you aren’t being charged more than you should. For those who live in BC and are confused at what items are say tax exempt you can see a good list at http://www2.gov.bc.ca/assets/gov/topic/BED47DA4EBDBA60A5F28622B8B2E1451/uploads/whats_taxable_whats_not.pdf .
