During the preparation of client's financial statements we found the problem and informed the client about the issue of one transaction that generated significant tax liability. Fortunately, we found that this transaction was not finalized until the moment of preparing management accounts.  The client was taken aback by this fact and immediately transferred the company to our office to handle all tax and accounting concerns.  Therefore, the client didn't finalize the transaction what resulted in a 150.000 Euro tax savings. Relying to our recommendation for carrying out a specific transaction, the client rerooted the transaction in order to minimize tax liability in the end.
