Example 14: Calculating a capital loss
Antonio acquired a new income-producing asset on 28 September 1999 for $100,000, including stamp duty and legal costs. He sold it for $90,000 in November 2018. During the period he owned it, he was allowed capital works deductions of $7,500. Antonio works out his capital loss as follows:
Cost base  | 
$100,000  | 
less capital works deductions  | 
$7,500  | 
Reduced cost base  | 
$92,500  | 
less capital proceeds  | 
$90,000  | 
Capital loss  | 
$2,500  | 
End of example
Example 15: Calculating a capital loss
In July 1996, Chandra bought 800 shares at $3 per share. He incurred brokerage and stamp duty of $100. In December 2018, Chandra sold all 800 shares for $2.50 per share. He incurred brokerage of $75. He made a capital loss, calculated as follows:
Calculation of reduced cost base
July 1996  | 
Purchase price  | 
$2,400  | 
July 1996  | 
Brokerage and stamp duty  | 
$100  | 
December 2018  | 
Brokerage  | 
$75  | 
Reduced cost base  | 
  | 
$2,575  | 
Calculation of capital loss
Reduced cost base  | 
$2,575  | 
Capital proceeds (800 × $2.50)  | 
$2,000  | 
Capital loss  | 
$575  | 
End of example
However, the reduced cost base is not relevant for some types of CGT events. In these cases, see appendix 1 for the amounts to use for the particular CGT event.
