Australia's Tax Practitioners Board (TPB) has cancelled the registration of C&N Southwest Sydney after finding serious breaches in professional conduct and determining that the company no longer met registration requirements.
The tax watchdog's investigation concluded that C&N Southwest Sydney director Elle Ristevski, along with de facto and shadow director Peter Ristevski, were no longer "fit and proper persons", a statement said.
According to the TPB, the Sydney-based company violated 12 provisions of the code of professional conduct.
The investigation found evidence that the business gave false or misleading information to the TPB during its inquiries.
The board also found that false or misleading information had been supplied to the Australian Securities and Investments Commission (ASIC) and the Australian Taxation Office (ATO). The information was used to support clients in appointing 'straw directors'.
