The first thing you should do when you receive a request from the Tax Agency is to analyse the situation, review exactly what they are asking you for and see if they can be right or not, that way you will have a first view of the issue. Once you have analysed everything, you can respond to the request through the AEAT and provide the requested documentation, but it is very important that from the beginning you know how to understand the situation and what they are looking for. As for helping you, of course, we take care of answering the requests you may have for your business, all online or in person.
