Hi,
I understand that the annual ISA allowance is £20,000. I did not deposit any amount into any ISA this year. If I deposit that amount between now and 5th April (the end of the tax year), in my IG ISA share dealing account but I don't buy any shares with this amount, would I still be able to deposit £20,000 from April 5th onwards to my account to make my total funds £40,000 which I can then decide how to invest and which shares to buy?
