I'm not in the EU I'm not subject to their regulations.
Unfortunately yes, you are.
No, this simply isn't correct. If you're outside the EU, you are not under EU jurisdiction, and not subject to their regulations. PERIOD, end of story.
That said, it most certainly is true that EU tax officials have a long history of bullying people worldwide with threats that lack any legal basis, but are often effective intimidation tactics. Ignoring them is an effective countermeasure.
What's more, if you want to sell within the EU you are required to obtain an EU VAT registration.
A grey area comes into play in the following regard. It IS true that if you are holding out a product or service INSIDE the EU then you are very much subject to their regulation and must collect VAT. European regulators are fond of "interpreting" this to mean than anyone selling anything to a European BUYER is "offering a service in the EU", and must collect tax. Their interpretation is complete BS, and can be ignored in many cases.
If we're talking about Amazon or Barnes & Noble or another company that clearly has OPERATIONS inside the EU, they definitely have to collect the tax, and they have little choice but to accept the interpretation that any online sale to any buyer inside the EU is taxable.
But if you are operating your own website in a non-European TLD such as .com, you are perfectly within your rights to simply ignore them. They have no jurisdictional authority over you. To be sure they will cite "official" EU regulations which say that all sellers all over the world are required to collect their tax. The correct answer is F.U. They have no recourse, and their laws and regulations have no binding legal effect outside their territorial jurisdiction.
The assertions made elsewhere that they could send debt collectors after you are nonsense. To accomplish that they would need a court judgment in the jurisdiction you actually reside in, meaning a court in your country has to agree to uphold their law, even though you are not subject to their law. That would never happen.
You have no obligation to obey any law imposed by the EU unless you are in the EU or doing business in the EU. As much as they would like to pretend that selling something on a website outside the EU to a buyer who happens to be in the EU violates their rules or constitutes doing business in the EU, if you're outside their territorial jurisdiction, they have no authority over you. Period, end of story. They don't like it, and they try hard to pretend they have more authority than they do because these intimidation tactics work on most people. Smart people just laugh off their threats and ignore them. Doing so is NOT illegal.
