I have noted a proposed budget allocation to increase the scope of ATO audit and datamatching in the area of personal assets. Appears that it is believed many people are trading in assets that could be subject to CGT on websites and ATO want a cut. These people are believed not to hold ABNs and are appearing to be small one-off sellers but often they do have regular sales. Here are the broad CGT issues : Guide to capital gains tax 2012-13 | Australian Taxation Office Most taxpayers think of CGT assets as property, shares and investments but a far broader range of assets are subject to CGT : Art, antiques, drawings, maps, framed items, sculpture, ceramics, aboriginal / cultural artefacts etc. These assets can be described as collectables or personal use assets and each has special rules. Personal use assets costing $10K or more are subject to CGT if a profit is made. eg boat, antiques (that arent a collectable / set). Collectables which cost under $500 (item or set) are excluded but coins, stamps, books, manuscripts etc may also be subject to CGT.
