It's a new law coming in Jan 1st 2015 that sales of digital products to EU countries will have to charge VAT according to the country of the customer. This law is supposed to deal with the issue of large companies basing themselves in low tax places such as Luxembourg....BUT....it has a 0 threshold, which is the part I can't fathom.

I searched for relevant terms on here but couldn't find anything so assume it has not been mentioned yet.
