Effectively or not, I expected to see more tax being paid purely because they'd have to pay VAT. Regardless of who effectively pays, they still have to transfer about 20% of all revenue gathered from selling to consumers. So I was curious as to why these numbers didn't add up. I'm perfectly ok with someone telling me why I'm wrong as well, I'm no accountant.
