How It Works
How this is calculated
- 1
Capital gain = sale proceeds less the cost base (purchase price plus eligible costs such as stamp duty, legal fees and capital improvements, and selling costs).
- 2
Capital losses are deducted first, then the 50% discount applies if the asset was held for at least 12 months.
- 3
The net capital gain is added to your other taxable income to estimate the extra tax, including Medicare.
