Main residence – compulsory acquisition

The main residence exemption can apply to certain compulsory acquisitions (or similar arrangements) which are associated with your main residence but not with your dwelling.

You can ignore a capital gain or capital loss you make from a compulsory acquisition (or similar arrangement) that happens only to land that is adjacent to:

• a dwelling that is your main residence, or
• a dwelling that passed to you as a beneficiary or trustee of a deceased estate.

The main residence exemption will apply to the extent that the land was used primarily for private or domestic purposes in association with the dwelling.

The maximum area of vacant land covered by the exemption is two hectares less the area of land underneath the dwelling.

This applies to CGT events that happen on or after 29 June 2011.

You also have the choice to apply the main residence exemption to CGT events that happened during the transitional period:

• starting at the beginning of the 2004–05 income year
• ending immediately before 29 June 2011.

The main residence exemption applies to structures adjacent to a flat or home unit, such as a garage or a storeroom, in the same way as it applies to land adjacent to a dwelling.

A partial CGT exemption may apply where the dwelling was:

• not used as a main residence during all of the relevant ownership period, or
• used for income-producing purposes.

• Partial exemption
• Dwelling used to produce income

The exemption for compulsory acquisitions of part of your main residence can apply to all the relevant CGT events, which is broader than the CGT events that the ordinary main residence exemption can apply to.

If you are a foreign resident when a CGT event happens to your residential property in Australia under a compulsory acquisition arrangement you may no longer be entitled to claim the main residence exemption. There is a transitional period for properties acquired before 7.30pm AEST on 9 May 2017 which are disposed of on or before 30 June 2020.

What is compulsory acquisition?

All levels of Australian Government or entities acting on behalf of government can compulsorily acquire land and associated structures or an interest in land for a public purpose.

Compulsory acquisition involves your ownership interest in the land being compulsorily acquired by:

• an Australian Government agency (that is, by the Australian, a state or a territory government or by an authority of the Australian, a state or a territory government), or
• a non-government entity authorised to do so under a power conferred by an Australian law.

The acquirer serves a notice on the landowner inviting them to negotiate for the disposal of the asset or part of the asset. This notice should inform the landowner that if negotiations are unsuccessful, the acquirer will proceed to acquire the asset or part of the asset in accordance with its legislative powers. Even if the landowner accepts the initial or negotiated offer, this is viewed to be a compulsory acquisition. This type of negotiated disposal is referred to as an acquisition under the shadow of compulsion.

This would typically involve:

• compulsorily acquiring part of the land adjacent to your residence, or
• compulsorily acquiring a structure such as a garage, storeroom or other structure associated with your flat or home unit.

Arrangements similar to a compulsory acquisition include the following:

• Your ownership interest in the land is compulsorily cancelled (however described), including compulsorily terminated or revoked.
• Your ownership interest in the land is varied (however described), for example, removing your ownership right to further develop the main residence. It could restrict your ability to erect structures above a certain level, for example installing antennas or remove your right to dig below the soil inhibiting your ability to undertake any further structural development of the property.
• Your ownership interest in the land is surrendered (however described) or varied (however described) under the shadow of compulsion.
• An interest or right in, or relating to, your land is compulsorily conferred on an Australian Government agency or an entity under a power conferred by an Australian law, for example, compulsorily creating a right of access over part of land adjacent to your dwelling.
• You confer on an entity an interest in, or right in, or relating to, your land under the shadow of compulsion, for example, compulsorily negotiating an agreement in relation to a temporary right in relation to your main residence. Government could require temporary access through your property to improve property that is used for a public purpose.
• Your ownership interest in the land was conferred on you by an Australian Government agency for a limited, but renewable period of operation, and that ownership interest was not renewed by that agency. For example, a right that you hold over the land is not renewed, such as a Crown lease.

The exemption does not apply to compulsory acquisitions, or similar arrangements, of adjacent land or a structure where the dwelling to which they relate is outside Australia.

Choosing how much of the land and associated structures will be part of your main residence

If your property exceeds two hectares you will need to determine how much and which parts of your property will form part of your main residence exemption area.

If the land used for private purposes is greater than two hectares, you can choose which two hectares are exempt.

Land exceeds two hectares

Calculation element	Hectares	Square metres
Main residence	0.0345	345
Swimming pool	0.0044	44
Dam 1 (pump water to landscaped gardens)	0.3500	3,500
Garage	0.0100	100
Guest house	0.0153	153
Driveway	0.1000	1,000
Landscaped gardens	1.4857	14,857
Total	2.00	20,000

Maximum exempt area

Where you have previously disregarded one or more capital gains or losses for a compulsory acquisition (or similar arrangement) of adjacent land or structure, the maximum area of adjacent land available for the main residence exemption when the dwelling is eventually sold (or otherwise realised) is reduced. The reduced area is called the ‘maximum exempt area’.

However, the maximum exempt area is only reduced by a previous compulsory acquisition or similar arrangement where you lost rights to the substantial use and enjoyment of that land either completely or for at least 10 years.

This rule ensures you are not disadvantaged by having to reduce your maximum exempt area where you have lost only insubstantial rights to the use and enjoyment of the exempt land. It also ensures that you are not disadvantaged where you lose substantial rights to the use and enjoyment of the exempt land but only for a short term such as under a short-term lease. This means that such land will remain eligible for a later application of the main residence exemption.

Examples of compulsory arrangements that do not result in substantial loss of rights to the use and enjoyment of the land might include where an easement is granted over vacant land which still permits the use and enjoyment of the land. Another example might be where the government compulsorily acquires subsurface land under your main residence. If you did not use or enjoy the subsurface land and the compulsory acquisition did not result in you losing rights to the substantial use and enjoyment of the surface land, then the maximum exempt area would not be reduced.

Exemption conditions to be met

Where you satisfy all of the following conditions any capital gain or capital loss arising from the compulsory acquisition (or similar arrangement) of adjacent land or structure without the dwelling is automatically disregarded.

The conditions that must be met are:

• you are an individual
• the exempt land is all or part of a dwelling’s adjacent land at the time of the CGT event
• the CGT event does not happen in relation to the dwelling or your ownership interest in the dwelling
• one of the following applies  
  • the dwelling was your main residence during some or all of the period you owned it
  • your ownership interest in the dwelling passed to you as a beneficiary in a deceased estate, or
  • you own the ownership interest in the dwelling as the trustee of a deceased estate
   
• the adjacent land or structure is compulsorily acquired or is the subject of a similar compulsory arrangement
• the sum of the following is two hectares or less  
  • the area of all of the dwelling’s adjacent land at the time of the CGT event
  • the area of land on which the dwelling is built
  • for each earlier CGT event that resulted in a capital gain or capital loss being disregarded under this exemption, the area of adjacent land exempted at the time of the earlier CGT event, but only if that involved reducing the area of the dwelling’s adjacent land at the time of that earlier CGT event.
   

This last condition ensures that you will not be disadvantaged by double counting of the same area of land where you have not lost substantial use and enjoyment of the land, for example, a compulsory easement is created over land but you retain ownership of the land affected by the easement, although with diminished rights.

Where you satisfy all of the conditions apart from the last condition (that is, where the sum of the relevant areas of land is more than two hectares), there is no automatic disregarding of any capital gain or capital loss arising from the compulsory acquisition (or similar arrangement).

In these circumstances, you can choose to disregard so much of the capital gain or capital loss that relates to an area of adjacent land that is compulsorily acquired (or subject to a similar arrangement) that is not more than the maximum exempt area.

Record keeping requirements

With all assets you need to keep records. In this case, you will need to keep records of the transactions or events that provide evidence of your assessment of how the main residence capital gains tax exemption applies to the part of your main residence that has been compulsorily acquired. This includes a record of your calculations of your capital gain or loss and if your property is greater than two hectares.

To find out more about the recordkeeping requirements in relation to assets and capital gain tax see Keeping records.

Choosing during the transitional period

A taxpayer who makes a choice to apply the exemption during the transitional period must do so:

• by the day they lodge their income tax return for the income year that includes the commencement day, or
• within further time allowed by the Commissioner.

The way you prepare your tax return for the applicable income year is sufficient evidence of you making a choice.

However, this does not preclude you from making a choice or providing evidence of a choice in a way other than the way you have prepared your income tax return for the applicable income year.

For example, lodging an objection to an assessment in the transitional period would also be sufficient evidence of you making a choice if the basis of the objection were to apply the main residence exemption to CGT events happening in the transitional period.
