Why, why indeed?
The short answer is always bureaucracy.
In Canada, I just had to register to collect VAT for free, I collect, and I send back to the Canadian Revenue Agency, as a sole trader, for free.
In Europe, I can only collect VAT from you and save you from this hassle if I’m registered as a company and acquire a VAT id or IOSS number, I would have to spend hundreds of euros to hire a professional, then I’d have to pay for the registration itself, then I’d have to pay for both every year for the upkeep of the accounts, and finally I have to also pay the corporate taxes. At this moment doing the VAT registration is a sure way for me to end up living under a bridge.
By the way, one way or another I am also forced to increase the shipping prices in order to be able to pay VAT I get charged by the printers.
The European tax and commerce system seems designed to keep the poor poor, and so are the current biggest ecommerce platforms which are exclusive only to established business with numerous employees and a solid financial situation.
No wonder we are in recession.
As an artist/designer/illustrator, I dream for the day when me and other creatives can make enough sales that we can sustain a life with a shop, but the reality is that the current world is crushing and extinguishing individual creatives like me before we even get started.
That said, I still hope that humanity will see the light eventually.
