If members of your self-managed super fund (SMSF) intend to claim a personal super contributions deduction, they need to be eligible and ensure they:
supply the SMSF trustee with a Notice of intent to claim or vary a deduction for personal super contributions
obtain written acknowledgment from the SMSF trustee of the notice of intent before lodging their 2019 individual tax return.
We've recently updated our website to help your members understand what personal super contributions are and how to claim a tax deduction correctly.
