tax dept assumes that the first sale of a stock parcel corresponds with the first purchase of a stock parcel unless you advise them otherwise.

so if you want to trade a parcel of shares in the short term independently of a seperate parcel with a longer term horizon of the same company you need to advise them. My accountant handles this for me so I’m unsure of the procedure. I just let him know that the parcel I sold came from a parcel acquired on such and such a date if I have been accumulating them over a few years. This all coincides with the annual statement I receive from my trading platform (mac bank) so he easily has a technical reference.

hope that helps
