My tax agent recently amended my FY19 return to include a capital gain that was missed in the original return.
I've subsequently reviewed my previous returns and have discovered a capital loss recorded in FY14 that hasn't been carried forward in subsequent years. There was no capital gains tax event in FY15 so it looks like it was just an oversight (or sloppy administration by my agent).
Anyway, to take advantage of this loss, do I need to amend all returns from FY15 onwards and then re-amend the FY19 return to offset the capital gain against the carried forward capital loss or is there a simpler way?
