18.104.22.168 TFN Requirements for Non-residents
To make an effective claim for FTB, an individual must supply their TFN and the TFN of their partner (1.1.P.30), if they have one. Where their partner is not residing in Australia, they may not have a TFN. Non-residents of Australia who do not have a TFN must apply for one by completing the 'TFN - Application or enquiry for individuals living outside Australia' (NAT2628). The ATO will give priority to an individual and their partner if a TFN is required for FTB purposes.
Declining to provide a TFN statement is not an offence, but the applicant's FTB claim may not be effective or their FTB payment may cease to be payable if a TFN statement is not provided.
