Here is a tax office view.

If you wish to continue to hold INL and if you have the cash, consider buying a new parcel of INL and holding both parcels for a few weeks ( if strategically sensible).

That way you have two parcels "at risk" and this surely could not be a CGT wash for TAX purposes only... becuase boh parcels are at risk.

If it then suits you, consider selling the volume that you wanted to sell in the first place.
