How we worked it out

Updated as you change the numbers.

  1. Net gain = $20,000.00 × 50% = $10,000.00.
  2. Tax = tax on (other income + net gain) − tax on other income, each with the low income tax offset and the 2% Medicare levy.

Method and assumptions

ATO: individuals who are Australian residents can reduce a capital gain by 50% on assets held for at least 12 months; the net capital gain is taxed as part of taxable income at 2026–27 resident rates.
