John’s story
John is 55 with a $240,000 super balance. He contracts as a nurse at a busy city hospital and earns around $127,000 per year. He plans to retire at 67 and wants to boost his super by making additional contributions of $250 per week*. He also intends to claim a tax deduction for these contributions.

John’s goals

  • Grow his super balance significantly before retirement.
  • Reduce his taxable income through deductible contributions.
  • Maintain flexibility while working as a contractor.
Rules and eligibility
  • John is under 75, so he can make personal contributions and claim a tax deduction.
  • Annual concessional contribution cap: $30,000 (includes deductible personal contributions).
  • To claim personal (after‑tax) super contributions as a tax deduction, John must notify his super fund by lodging a Notice of intent to claim or vary a deduction form.
  • Deductible contributions are taxed at 15% inside super, usually lower than the marginal tax rate.

How tax deductions work

  • John claims his $13,000 annual contributions as a tax deduction, reducing his taxable income from $127,000 to $114,000.
  • This lowers his tax bill by roughly $4,100 per year.
  • Super contributions are taxed at 15%, which is considerably lower than his personal tax rate.

By making regular after-tax contributions and claiming a tax deduction, John can transform his retirement outlook, growing his super from $240,000 to around $638,000.

The case study is based on current regulatory requirements and laws, including tax rates, which may be subject to change.
