Since 1st January 2015 EU made a major change to its VAT regulations that requires businesses to pay VAT according to the locations of consumers. This was meant mainly for large companies that have been avoiding higher taxes by establishing presences in places with lower VAT. Unfortunately, this also put a burden on independent creators who sell digital products to customers in Europe.
In Yclas we will collect that VAT and register it on our MOSS agency. You do not need to worry about anything. If you are a company registered on the VIES, you can edit your profile and add your EU VAT number and we will not charge VAT if it's a valid registered company.
