The ATO advises that people can now apply for their Tax File Number (TFN) online and authenticate their proof of identity documents at participating Australia Post retail outlets.
Australian residents aged 16 years and older can apply for a TFN here and lodge their application form at a participating Australia Post retail outlet.
Over 230 participating Australia Post retail outlets nationally will provide the service from February, with a total of 475 outlets to offer the service by end June 2013. A full list can be viewed here.
Current paper TFN application forms available via newsagents around the country are not accepted as part of the Australia Post service. You can visit the ATO website here to find out more about applying for a TFN.
