I'm sorry if this gets asked a lot.
I understand that it is okay to open more than one ISA in a year, but you may only pay into one of them in a given year - the other should be left untouched (if I understand correctly). Now, does the same apply to the Lifetime ISA? I'm guessing that it's okay to invest into both in a given year, because the £4k limit of a LISA counts into your £20k limit overall, so I believe that it's okay to invest into both.
HOWEVER. I may have missed something. The reason I think this is because logging into either of my accounts (one at Hargreaves Lansdown, the other at Vanguard UK), reveals a 'remaining ISA limit' - telling me how much more money I am permitted to save before next April. The problem is that neither value I am shown seems to take the other into account. I have so far invested £650 into my Vanguard ISA, and it tells me my remaining allowance is £19,350. That would be fine, except I've invested more money into my HL LISA, meaning my actual allowance should be lower than that.
Is this normal, or was I supposed to link these accounts/inform someone that they are owned by the same person? I mean I had to enter my NI number both times, so I'd like to have thought that something would have pinged on a database somewhere and made the link for me.
It's an innocent mistake if this is wrong, and the last thing I'd want to do is cause any grief for this, so in the event of an error, I'd rather 'come clean', admit my error and make amends rather than be 'found out' - because the latter makes it seem more malicious than it actually is.
Thanks!
