Question about VAT recovery on foreign invoices

Good day,

I am starting as a self-employed student in the coming weeks and am currently entering my start-up costs.

However, I have a few invoices from suppliers in the Netherlands, Germany, etc., on which vAT has already been charged. When I enter these now, the system indicates that this vAT is not recoverable.

Can you let me know if there is a way to recover this foreign vAT, and yes, what procedure I need to follow?

Thank you in advance for your help.

Kind regards,
Daniel Gonski
