Hello!
I have recently started a sole proprietor as a secondary occupation, with vAT exemption. In the learning center, I read that it is best not to provide your Belgian vAT number to Dutch (or other foreign) suppliers.
Now I am creating a professional account at a webshop where I often order as a private person. They also ask for my vAT number.
Could this affect my exemption status? In other words, am I doing something wrong if I provide it and it is stated on invoices?
