EU VAT and tax obligations about dropshipping stores


New Member
Dear friends, I am in the process of opening a new alidropshipping store. I was wondering as a EU citizen what are my obligations concerning the volume of sales and my income. Can anyone tell me:
*After which volume of sales am I obliged to have a VAT account, and at which country?
*What are the fees of PayPal transactions and what are the problems faced with PayPal withdrawals?
* Are there any obligations I need to know concerning invoicing, income tax and other EU restrictions on sales?

Waiting for your answers...
