What you can do with this worksheet
This worksheet will help you to calculate a capital gain or capital loss for each separate CGT asset or CGT event using either the:
If you bought and sold an asset within 12 months, you must use the 'other' method to calculate your capital gain.
If you owned the asset for 12 months or more, you can use either the discount method or the indexation method, whichever gives you the better result.

The following information will help you when completing the worksheet:
Splitting parcels of shares
Each share in a parcel of shares is a separate capital gains tax (CGT) asset. This means you can use different methods to work out the amount of any capital gain for shares within a parcel. This may be to your advantage if you have capital losses to apply. See the example of Clare.
Choosing the indexation or discount methods
For assets you acquired before 11:45 am (by legal time in the ACT) on 21 September 1999 and have held for 12 months or more, you can choose to use the indexation method or the discount method to calculate your capital gain. There is no one factor you use as a basis to select the better option as it depends on the type of asset you own, how long you have owned it, the dates you owned it and past rates of inflation. Because capital losses must be offset against capital gains before the discount is applied, your choice may also depend on the amount of capital losses that you have available. Note: For the indexation method inflation after 21 September 1999 is not taken into account.
Example: Choose the indexation or discount method
Justin sold some land and has a $10,000 capital gain under the discount method (before applying the CGT discount) or a $7,000 capital gain under the indexation method. If Justin has no capital losses the discount method will produce the smaller capital gain (that is, $5,000).
However, Justin also made a capital loss of $5,000 on the sale of some shares. He will be better off using the indexation method to work out the capital gain from the sale of his land.
Under the indexation method his net capital gain is:
- $2,000 ($7,000 − $5,000).
If he used the discount method, his net capital gain would be:
- $2,500 [($10,000 − $5,000) × 50%].
The example below shows that applying one method to work out your capital gains on a whole parcel of shares you acquired before 21 September 1999 may not be to your advantage if you have capital losses or net capital losses to apply.
In this situation, you will get a better result if you apply the indexation method to sufficient shares to absorb the capital loss (or as much of the capital loss as you can) and apply the discount method to any remaining shares.
Example: Capital gains on shares where you also have capital losses
Clare sold a parcel of 500 shares in March 2023 for $12,500; that is, for $25 each. She had acquired the shares in March 1995 for $7,500; that is, for $15 each, including stamp duty and brokerage costs. There were no brokerage costs on the sale of her shares. Clare had no other capital gains or capital losses in 2022–23, although she has $3,500 net capital losses carried forward from previous income years.
Because Clare owned the shares for more than 12 months, she can use the discount method or the indexation method to work out her capital gains – whichever gives her a better result. Clare decides to work out her net capital gain by applying both the discount method and the indexation method to the whole parcel of shares:

Note 1: $7,500 × (68.7 ÷ 63.8 = 1.077)
However, because each share is a separate asset, Clare can use different methods to work out her capital gains for shares within the parcel. The lowest net capital gain would result from her applying the indexation method to the sale of 395 (see note 2) shares and the discount method to the remaining 105. She works out her net capital gain as follows:
Indexation method (395 shares)
Capital proceeds |
($25 each) $9,875 |
Cost base |
(395 × $15 × 1.077) $6,381 |
Capital gain |
$3,494 |
less capital losses |
$3,500 |
Capital gain/(loss) |

CGT discount method (105 shares)
Capital proceeds |
($25 each) $2,625 |

less any remaining capital losses |

Subtotal |
$1,044 |

$522 |
Net capital gain |
$522 |
Note 2: To calculate this, Clare worked out the capital gain made on each share using the indexation method ($4,423 ÷ 500 = 8.85) and divided the capital loss by this amount ($3,500 ÷ 8.85 = 395).
End of exampleIt is probably best to calculate your capital gain using both methods to find out which gives you the better result. This is shown below in the worked example for Val.
Example: Choosing the indexation or discount method
Val bought a property for $150,000 under a contract dated 24 June 1991. The contract provided for the payment of a deposit of $15,000 on that date, with the balance of $135,000 to be paid on settlement on 5 August 1991.
She paid stamp duty of $5,000 on 20 July 1991. On 5 August 1991, she received an account for solicitor’s fees of $2,000, which she paid as part of the settlement process.
She sold the property on 15 October 2022 (the day the contracts were exchanged) for $350,000. She incurred costs of $1,500 in solicitor’s fees and $4,000 in agent’s commission.
Val's capital gain calculated using the indexation method

Capital proceeds |
$350,000 |
less cost base |
$188,213 |
Capital gain |
$161,787 |
(Val's total current year capital gain using this method)
Assuming Val has not made any other capital losses or capital gains in the 2022–23 income year and does not have any unapplied net capital losses from earlier years, her net capital gain using the indexation method is $161,787.

End of example
Example: Shares purchased and given away more than 12 months later
In May 1999, Andrew bought 1,200 units in Share Trust for $1,275. This amount included brokerage fees. He gave the units to his brother, in August 2021. A CGT event happens when Andrew makes the gift. At the time of this CGT event, the units were worth $1,595. As the market value of the units is greater than their cost base, Andrew has made a capital gain.
As Andrew bought the units before 21 September 1999 and he owned them for more than 12 months, he can use the indexation or discount method to calculate his capital gain, whichever gives him the better result.
Indexation method
If Andrew calculates his capital gain using the indexation method, he indexes the cost of his units and the incidental costs of buying them as follows:
The indexation factor is:
CPI for September 1999 quarter ÷ CPI for June 1999 quarter
68.7 ÷ 68.1 = 1.009
His indexed cost base is:
His cost ($1,275) × The indexation factor (1.009) = $1,286.48
So his capital gain is:
Capital proceeds |
$1,595.00 |
Less indexed cost base |
$1,286.48 |
Capital gain |
$308.52 |
Rounded down |
$308.00 |
Discount method
If Andrew uses the discount method, his capital gain is calculated as:
Capital proceeds |
$1,595 |
Less cost base |
$1,275 |
Capital gain |
$320 |
Less discount (see note 3) |
$160 |
Capital gain |
$160 |
Note 3: Andrew does not have any capital losses. If he did, he would deduct any capital losses before applying the discount.
Andrew chooses the discount method because it gives him a smaller capital gain.
End of exampleIf, during the period of owning the units, Andrew had received a non-assessable payment from the fund, his cost base may have been reduced and the capital gain may have been greater.
Using multiple methods
In the examples following, Tony uses the indexation method, the discount method, and the 'other' method, to calculate his capital gain so he can decide which method gives him the best result. This example shows you how to complete the capital gain or capital loss worksheet to calculate your capital gain when you acquire or dispose of shares.
Remember that if you bought and sold your shares within 12 months, you must use the ‘other’ method to calculate your capital gain. If you owned your shares for 12 months or more, you may be able to use either the discount method or the indexation method, whichever gives you the better result.
Because each share in a parcel of shares is a separate CGT asset, you can use different methods to work out the amount of any capital gain for shares within a parcel. This may be to your advantage if you have capital losses to apply. See the example of Clare.
Example: Using all three methods to calculate a capital gain
On 1 July 1994, Tony bought 10,000 shares in Kimbin Ltd for $2 each. He paid a stockbroker’s fee of $250 and stamp duty of $50.
On 1 July 2021, Kimbin Ltd offered each of its shareholders one right for each four shares owned to acquire shares in the company for $1.80 each. The market value of the shares at the time was $2.50.
On 1 August 2021, Tony exercised all rights and paid $1.80 per share.
On 1 December 2021, Tony sold all his shares in Kimbin Ltd for $3.00 each. He incurred a stockbroker’s fee of $500 and stamp duty of $50.
Note: Separate records
Tony has two parcels of shares – those he acquired on 1 July 1994 and those he acquired at the time he exercised all rights, 1 August 2021. He needs to keep separate records for each parcel and apportion the stockbroker’s fee of $500 and stamp duty of $50.
The completed Capital gain or capital loss worksheet (PDF, 143KB)This link will download a file shows how Tony can evaluate which method gives him the best result.
He uses the 'other' method for the 2,500 shares he owned for less than 12 months, as he has no choice:
Capital proceeds |
$7,500 |
less Cost base |
$4,610 |
Capital gain |
$2,890 |
For the 10,000 shares he has owned for 12 months or more, his capital gain using the indexation method would be:
Capital proceeds |
$30,000 |
less Cost base |
$23,257 |
Capital gain |
$6,743 |
This means his net capital gain would be:
'other' method + indexation method = net capital gain
$2,890 + $6,743 = $9,633
If Tony uses the discount method instead (assuming he has no capital losses), his capital gain would be:
Capital proceeds |
$30,000 |
less Cost base |
$20,740 |
Capital gain |
$9,260 |
He applies the CGT discount of 50%:
$9,260 × 50% = $4,630
This means Tony’s net capital gain would be:
'other' method + discount method = net capital gain
$2,890 + $4,630 = $7,520
In this case, Tony would choose the discount method, rather than the indexation method, as it gives him the better result – that is, a lower net capital gain.
