Reasons for decision

Subdivision of land 

The subdivision of land itself does not constitute a capital gains tax (CGT) event. Where a property that was acquired as one asset is subdivided, the new assets are treated as though they were always separate assets.

Therefore, the subdivided blocks will retain the acquisition date of the original property.

The cost base of the original property will need be apportioned between the subdivided blocks on a reasonable basis.

Taxation Determination TD 97/3 (enclosed) provides that the Commissioner will accept any reasonable method of apportioning the original cost base between the new blocks (that is, on an area basis or relative market value basis).

A reasonable apportionment of the original cost of the land itself can usually be achieved on an area basis if all the land is of similar size and market value or on a relative market value basis if this is not the case.

Subdivision costs

The costs of subdivision should also be apportioned between the blocks. If the blocks are of unequal market value the Commissioner considers that costs such as surveying, legal fees and application fees associated with the subdivision should be apportioned in accordance with the relative market values of the two blocks. However, any cost solely related to one block should be attributed solely to that block.

Please note - The costs of the demolition of a portion of the dwelling are solely attributable to the block of land containing the dwelling. Therefore, they do not form part of the cost base of the vacant block of land.

Therefore, the capital works costs associated with the demolition and re-instatement of services and facilities to the dwelling cannot be included in the cost base of the newly subdivided block of land, as they relate solely to the block with the dwelling.
