Self-lodgers must submit by 31 October 2026. Individuals registered with a tax agent before 31 October may have until 15 May 2027 to lodge. Business activity statements (BAS) have separate lodgement dates depending on your reporting frequency.
Super contributions must be received by your fund by 30 June to be deductible in the 2025-26 year. Contributions initiated on 30 June may not be received until July — check with your fund about their cut-off times. Bank-to-bank super transfers can take 1-3 business days.
