My question is how to treat this additional superannuation contribution in the tax return of the individual.

Additional superannuation contributions of $2,000 were paid to Bronte's superannuation account by her from her after tax pay. These contributions are in addition to superannuation paid as per the superannuation guarantee requirements of the company. Bronte had not provided her super fund with a notice of intent to claim a deduction. Details of the fund are Host Plus, account number 1235346, Fund ABN 23 111 144 445 and fund TEN 999999716
