I have early signs of dementia and nowadays I am bewildered with the rules to the extent that I become stressed and unable to make the necessary decisions so I am here for guidance. I have googled for examples of my situation and what to do, but found no clarity. Face to face with advisers I do not seem to be able to avoid pretending I understand either. I used to be able to understand all this once but not now. You may question how I decide what shares to buy and sell. I am ok there as I subscribe to a service that has been very good for 5 years now and I follow their advice 75%. Our return for 2016/17 has to be submitted soon. I'm 75, in pension mode and about 100K over the cap. There's $28K in cash and the rest in shares in 17 companies with amounts ranging from half under $100K and the rest $150K to $780K. Some shares held date back 10 years. I get $125K franked dividends and $54K franking credits and expect a refund of $27K. In general principle, for the 2016/17 return, how do I choose which shares to sell and what do I do about the new CGT relief "trick" / "re-setting" cost bases? Moving on, I look like being $1.8K over the cap at 30/6/2018 and think I have to apply for CGT relief again before then and I have seen mention of parcels of shares bought and sold for a given company?
