Interest Gained from ISA - is this included in your max allowance?


If I max out this years ISA and I then gain monthly interest - is this allowed or should I keep my balance below the max threshold to allow for additional interest to remain within the limit?

Any help appreciated!

    Any interest, even that earned on a fully funded ISA, is free from tax, either when added to the balance or withdrawn.

    The £20K annual ISA allowance relates only to contributions, so ignore interest/growth.
