The relevant FAO agency must contact the ATO and obtain either:
If TFNs are provided on contact, the claim should be determined.
If the ATO advises that:
see FA Guide 4.2.4.110 Claim Action 11 - ATO Advises FAO No TFN.
If 28 days have passed since the claim for FTB was made and no response has been received from the ATO regarding the applicant's statement that either they do not know their TFN or that an application for a TFN is pending, then the claim should be determined. When the ATO responds to the request the claim should be reviewed in accordance with the information obtained from the ATO.
An electronic or paper file record of this advice should be kept.
