Explanation of terms

You may make a capital gain from a CGT event such as the sale of an asset. Generally your capital gain is the difference between your asset's cost base (what you paid for it) and your capital proceeds (what you received for it). You can also make a capital gain if a managed fund or other unit trust distributes a capital gain to you.

Capital gains tax (CGT) refers to the income tax you pay on any net capital gain you make and include on your annual income tax return. For example, when you sell (or otherwise dispose of) an asset as part of a CGT event, you are subject to CGT.

Generally, you may make a capital loss as a result of a CGT event if you received less capital proceeds for an asset than its reduced cost base (what you paid for it). Your capital loss is your reduced cost base less your capital proceeds.

Capital proceeds is the term used to describe the amount of money or the value of any property you receive or are entitled to receive as a result of a CGT event. For shares or units, capital proceeds may be:

• the amount you receive from the purchaser
• the value of shares (or units) you receive on a demerger
• the value of shares (or units) and the amount of cash you receive on a merger/takeover, or
• the market value if you give them away.

The CGT assets covered by this guide are shares and units.

However, CGT assets also include collectables (such as jewellery), assets for personal use (such as furniture or a boat) and other assets (such as an investment property, vacant land or a holiday home). If you have made a capital gain from the sale of one or more of these assets, you may need to read the Guide to capital gains tax .

These amounts are the CGT discount component of any actual distribution from a managed fund.

A CGT event happens when a transaction takes place such as the sale of a CGT asset. The result is usually a capital gain or capital loss.

The cost base of an asset is generally what it costs you. It is made up of five elements:

• money you paid or property you gave for the asset
• certain incidental costs of acquiring or selling it - brokerage, stamp duty, investment consultants fees and legal fees
• non-capital costs associated with owning it (generally this will not apply to shares or units because you will usually have claimed these costs as tax deductions)
• costs associated with increasing its value (for example, if you paid a call on shares), and
• what it has cost you to establish, preserve or defend your ownership or rights to it.

The cost base for a share or unit may need to be reduced by the amount of any non-assessable payment you receive from the company or fund.

This generally applies to CGT events that happen on or after 1 July 2002 to interests that you own in the head entity of a demerger group and a company or fixed trust is demerged from the group. Generally the head entity undertaking the demerger will advise owners whether demerger rollover is available but you should seek our advice if you are in any doubt. The Tax Office may have provided advice in the form of a class ruling on a specific demerger, confirming that the rollover is available.

This rollover allows you to defer your CGT obligation until a later CGT event happens to your original or your new shares or units.

A company demutualises when it changes its membership interests to shares. If you received shares as part of a demutualisation of an Australian insurance company (for example, AMP or NRMA), you are not subject to CGT until you sell the shares.

Usually the company will advise you of your cost base for the shares you received. The company may give you the choice of keeping the shares they have given you or of selling them and giving you the capital proceeds.

If you hold a policy in an overseas insurance company that demutualises, you may be subject to CGT at the time of the demutualisation.

The discount method is one of the ways to calculate your capital gain if:

• the CGT event happened after 11.45am (by legal time in the ACT) on 21 September 1999, and
• you acquired the asset at least 12 months before the CGT event.

If you use the discount method, you do not index the cost base but you can reduce your capital gain by the CGT discount of 50%. However, you must first reduce your capital gains by the amount of all your available capital losses (both current year and prior years) before you discount any remaining capital gain.

If you acquired the asset before 11.45am (by legal time in the ACT) on 21 September 1999, you can choose either the discount method or the indexation method, whichever gives you the better result.

A discounted capital gain is a capital gain that has been reduced by the CGT discount. If the discounted capital gain has been received from a managed fund, the amount will need to be grossed up before you apply any capital losses and the CGT discount.

Under these plans, shareholders can choose to use their dividend to acquire additional shares in the company instead of receiving a cash payment. For CGT purposes, you are treated as if you received a cash dividend and then used it to buy additional shares. Each share (or parcel of shares) received in this way is treated as a separate asset when the shares are issued to you.

Grossing up applies to unit holders who are entitled to a share of the fund's income that includes a capital gain reduced by the CGT discount. In this case, you 'gross up' your capital gain by multiplying by two your share of any discounted capital gain you have received from the fund.

The income year is the financial year relating to your current income tax return.

The indexation factor is worked out based on the Consumer Price Index (CPI) in appendix 2 of this guide.

The indexation of the cost base of an asset is frozen as at 30 September 1999. For CGT events after that time the indexation factor is the CPI for the September 1999 quarter (123.4) divided by the CPI for the quarter in which you incurred costs relating to the asset. The result is rounded to three decimal places. You may have different indexation factors for different amounts included in your cost base.

The indexation method is one of the ways to calculate your capital gain if you bought a CGT asset before 11.45am (by legal time in the ACT) on 21 September 1999. This method allows you to increase the cost base by applying an indexation factor to each item of expenditure in your cost base (based on increases in the Consumer Price Index up to September 1999).

This is an amount notionally included in a dividend from a listed investment company (LIC) which represents a capital gain made by that company. The amount is not included as a capital gain under item 17 on the tax return, or item 9 if you use the tax return for retirees. (Refer to the instructions for dividend income at item 11 on the tax return or item 8 if you use the tax return for retirees and this example .)

A net capital gain is the difference between your total capital gains for the year and your total capital losses (including capital losses from prior years), less any CGT discount or small business concession to which you are entitled.

You show the result at A item 17 on your tax return, or item 9 if you use the tax return for retirees.

A non-assessable payment is a payment received from a company or fund that is not assessed as part of your income on your income tax return. This includes some distributions from unit trusts and managed funds and, less commonly, from companies.

'Other' method

To calculate your capital gain using the 'other' method, you subtract your cost base from your capital proceeds. You must use this method for any shares or units you have bought and sold within 12 months (that is, when the indexation and discount methods do not apply).

The reduced cost base is the amount you take into account when you are working out whether you have made a capital loss when a CGT event happens. The reduced cost base may need to have amounts deducted from it such as non-assessable payments. The reduced cost base does not include indexation or non-capital costs of ownership such as interest on monies borrowed to buy the asset.

Rollover allows a capital gain to be deferred or disregarded until a later CGT event happens.

This can apply to CGT events that happen on or after 10 December 1999 in the case of a takeover or merger of a company or fund in which you have holdings. The company or fund would usually advise you if the rollover conditions have been satisfied. This rollover allows you to defer your CGT obligation until a later CGT event happens to your shares or units.

You may only be eligible for partial rollover if you received shares (or units) plus cash for your original shares. In that case, if the information provided by the company or fund is not sufficient for you to calculate your capital gain, you may need to seek advice from the Tax Office.

If you disposed of shares back to a company under a buy-back arrangement, you may have made a capital gain or capital loss.

Some of the buy-back price may have been treated as a dividend for tax purposes. The time you make the capital gain or capital loss will depend on the conditions of the particular buy-back offer.

If a company in which you held shares was taken over and you received new shares in the takeover company, you may be entitled to scrip-for-scrip rollover.

If the scrip-for-scrip conditions were not satisfied, your capital proceeds for your original shares will be the total of any cash and the market value of the new shares you received.

These amounts include indexation received by a managed fund on its capital gains and accounting differences in income. Tax-deferred amounts reduce both the cost base and reduced cost base of your units in a managed fund.

These amounts are generally made up of exempt income of the managed fund - such as amounts on which the fund has already paid tax or income you had to repay to the fund. Tax-exempted amounts do not affect the cost base and reduced cost base of your units in a managed fund.

These amounts allow the managed fund to pay a greater distribution to its unit holders. This is due to certain tax concessions funds can receive. Tax-free amounts affect the reduced cost base but not the cost base of your units in a managed fund.
