share washing, page-6

Just had a look and the 30 days is American guideline, ATO doesn't provide specific guidance "In Australia a magnitude of time is not specifically mentioned by the ATO. However where a series of trades is not judged to have an economic affect, other than to give rise to a capital loss and tax benefit, the trade can be knocked back for taxation purposes and the claimant lumbered with financial penalties."

Would be an idea to see an accountant, I'm certain the difference between doubling holdings and selling down half versus selling down all holdings and buying them back wouldn't be considered any different by the tax department, especially if it was all done in the same day for example. The intention is the same, and that's all that seems to matter for the ATO decisions (otherwise the wash sale rule would be a joke, being so easy to get around). Specifically, at no point did you reduce your economic exposure to the shares in question. Have also read maybe getting a spouse to do the buying might help your cause.
