Power of attorney

All reports to BUAK can also be submitted by third parties provided that they are professionally authorised representatives (lawyers, qualified professionals as per the Professional Accountants and Tax Advisors Act [Wirtschaftstreuhandberufsgesetz], accountancy professions, etc.).

This requires power of attorney. The power of attorney must be sent to BUAK. Log-in data for the eBUAK portal are issued only after the power of attorney has been received.
