ABN Registration

A tax file number (TFN) is a unique identifier issued by the Australian Taxation Office (ATO) to each taxpaying entity – individuals, companies, SMSFs, partnerships and trusts. TFNs were initially introduced to facilitate file tracking at the ATO but have since been expanded to encompass income and other data matching. They are a 9 digit number and may only be recorded or used specifically for authorised tax-related purposes.
