The ATO has examined more than 1000 cases of SMSF auditor number (SAN) misuse and has taken against 90 people as part of its rolling compliance efforts.

The ATO has reminded trustees they are legally required to appoint an approved SMSF auditor by 31 March or face the possibility of a large fine.

An ongoing review of SMSF auditors has continued to find concerns with their practices, with some being referred to ASIC for further action.

SMSF auditors have been slow in coming forward about the misuse of their auditor numbers, but the ATO has increased action on reported cases.
