RE: IAG in my ISA15 Sep 2020 17:25
I was faced with the same issue, however after speaking with AJBell (who I trade through), they've advised that despite my current IAG shares being in my ISA, I can buy the new shares via my usual trading account.
Whilst this isnt ideal and not within the ISA wrapper so wouldn't be tax free on any gains, I'm eligible to buy just over 9500 new shares, which is around £8.2k, I figured its unlikely IAG share price will have doubled before the start of April '21, so any "gains" will fall under my Capital Gains Allowance for this year and I will sell a few days before the end of the tax year and re-buy within my ISA come April 6th when my allowance renews.. with the only loss being some trading fees, a bit of stamp duty and whatever the difference in SP is between me selling and re-buying. (I'm holding this long term so want any potential upside to be tax free within my ISAs)
