Do you just give commsec confirmations csv files to your tax agent ? I tried to do that a few times in the past but they always tell me to match buys and sells myself, using spreadsheets like that one you linked...It took so much time I decided to make this tool that can take commsec confirmations downloaded from the site straight up. Maybe I'll ask my tax agent this year if he's interested!?.
