The ATO advises that it will send a superannuation fund an Invalid tax file number (TFN) (Section 299TB) notice if all the following occur:
- The fund has submitted a member contribution statement (MCS) that contained member records with incorrect TFNs.
- The ATO has issued the fund with a 'please resolve' letter.
- 60 calendar days have passed since the fund received the letter and the ATO still cannot find a TFN for a member.
