CBA TA update, page-985

A solution to your problem would be to sell part of your holding & buy back in at a lower level & instruct your accountant not to do a first in, first out adjustment to your holdings, when doing your tax return, but do a last in, first out which minimises your tax. I presume your last purchase was at the highest price paid. You then are up for tax only on the difference between the highest price paid & your sale price.

You then should scan your portfolio for that stock you have been holding for years, in a loss situation, that you wish you had never bought. Sell that stock at a capital loss & it will offset the capital gain on CBA.

In future years, if you have a stock with a sizeable capital loss, sell it in the same year as you sell more CBA shares. you can always buy CBA back at a later time. This would minimise your tax that would be paid when your CBA shares were eventually sold.

I hope that helps.
