HandiTax - IITR.EM0015 Date of birth (DOB) does not match ATO records in HandiTax

The ATO cross-checks taxpayer details like name, date of birth, and financial data (e.g. bank interest) when a return is lodged. If the submitted data doesn’t match their records, the return is rejected with an EM error. These are backend ATO errors and not part of the standard SBR error list. If you receive one, contact the ATO directly for clarification.
