They were just a couple of examples. If they were the only challenges, it wouldn't be a problem but I bet there are 1000s more (different in each country too.) and that target is constantly moving.

When I said simplification, I meant that if governments would ever accept that tax breaks and special cases are massively expensive to the companies who have to keep track of the changes and then pass on those costs to their customers, then we wouldn't need complex tax software and could use a SS. I can't see that ever happening but I would like governments to be on the hook for the decisions that cost business so much in admin/legals.
