It depends whether you buy this training as a private person or as a company (based in EU).
Short answer: Please fill in your billing address in the form on the Sign up page.
Long answer: The tax office asks 4c Unity (and any other supplier of digital services) to collect and hand over two non-contradictory means of evidence to determine the residence of a private person in the EU (without a VAT ID number) who buys this online training, like the billing address, bank details or ip address. So I need to prove that you live in the EU and in which country. So I can bill the right amount of taxes to you and pay the right amount to the tax office in your country. (Every EU country has its own tax amount). You will find ‘billing address’ in the form on the Sign up page. I would like to have the complete details. Please fill it in. The other two details you don’t have to fill in there. I will get those automatically when you pay the invoice and when you access the training. This tax legislation is called the MOSS legislation.
For tax reasons, companies based in the EU, need to fill in their VAT ID number, which 4c Unity should check first, before I can give you access to the training. Dutch companies don’t have to fill in their VAT ID number. They have to pay 21% taxes. In some countries the ‘reverse charge’ mechanism applies.
