Here in Spain I must declare all my incomes to the Spanish Tax Agency through invoices of my activity. I know that Verbling issues an invoice every week for the lessons completed but the data provided is not sufficient. For an invoice to be considered correct in Spain it must include the TIN or Tax ID of issuer and receiver. I have already wrote the support team but I got no answer by now... Does any of you have the TIN or Tax ID of Verbling and could provide it to me, please?
