About CGT concessions



This information may not apply to the current year. Check the content carefully to ensure it is applicable to your circumstances.

End of attention

If you made a capital gain from a CGT event that happened after 11.45am on 21 September 1999 (such as disposing of a CGT asset), you may be able to reduce the capital gain using either or both of the following:

  • the CGT discount
  • one or more of the four CGT concessions available for small business.

CGT discount

You may be eligible to use the CGT discount to work out your capital gain if you owned the relevant asset for at least 12 months.

The CGT discount is not limited to capital gains from business assets.

If you are an individual (including partners in partnerships) or a trust, the discount lets you reduce your capital gains by 50%. There are more rules for beneficiaries who are entitled to a share of a trust capital gain. The discount for complying super funds is 33.33%.


Companies cannot use the CGT discount.

When to apply the CGT discount

You apply the CGT discount after offsetting your capital losses against your capital gains, but before applying the small business CGT concessions (apart from the small business 15-year exemption).

Small business CGT concessions

The following four CGT concessions are available only for small business.

  • The small business 15-year exemption provides a total exemption for a capital gain on a CGT asset if
    • you have continuously owned the asset for at least 15 years
    • the relevant individual is 55 years of age or over and retiring or is permanently incapacitated.
  • The small business 50% active asset reduction provides a 50% reduction of a capital gain.
  • The small business retirement exemption provides an exemption for capital gains up to a lifetime limit of $500,000. If the individual is under 55 years of age just before they make the choice, the amount must be paid into a superannuation (or similar) fund.
  • The small business rollover allows you to defer all or part of a capital gain on a business asset for a minimum of two years. If you acquire a replacement asset or make a capital improvement to an existing asset within the period allowed, the gain is deferred until you
    • dispose of the replacement or improved asset
    • change its use in particular ways.

In this case, the deferred capital gain is in addition to any capital gain you make when you dispose of the replacement or improved asset.

How the CGT concessions work

To be eligible for any of the concessions, you must first meet several basic conditions, which are outlined in step 1.

You must then meet any additional conditions that apply specifically to the individual concessions.

You can apply as many concessions as you are entitled to until the capital gain is reduced to nil. This choice allows you to achieve the best tax result for your circumstances.

There are rules about:

  • the order you apply the CGT small business concessions
  • any current year or prior year capital losses
  • the CGT discount.
Further Information

See the flow chart.

End of further information

You may be able to apply either or both of the following to each capital gain:

  • more than one of the four concessions if you meet the conditions for each
  • the CGT discount if it also applies.

If the small business 15-year exemption applies, you can disregard the entire capital gain and, therefore, you do not need to apply any further concessions.

If you have more than one capital gain you can choose the order in which to reduce capital gains by capital losses.

The small business CGT concessions do not apply to gains from depreciating assets.
