Question: Is the client’s date of birth compulsory in the client’s ITR form?
Answer: Yes. The client’s date of birth is a required field on the “Individual Tax Return – 2025” form (for the period 1 July 2024 to 30 June 2025). The instructions explicitly list “all your personal details, including your date of birth” as necessary information. Australian Taxation Office+2Australian Taxation Office+2
Additionally, the form itself states:
“Your date of birth – If you were under 18 years old on 30 June 2025, you must complete question A1.” iorder.com.au+1
This indicates that leaving the date of birth blank may lead to processing delays or validation failure.
