Cryptic ISA fee question

[gldms]

I have a stocks and shares ISA with HargreavesLansdown. Aside from a monthly fee of £3.75 there is a one-off entry of -£23.61 “Transfer to capital account” in my Income History.  I’ve emailed HL for explanation, but no reply. There is plenty of cash in the ISA to cover the monthly fee and no shares were sold to cover the £23.61.  It looks like it was taken from my cash income. To add to the confusion, another entry (positive)  of £23.61 is listed as Transfer from Income account” in my Transaction History.  So, my ISA has a “Capital Account” and an “Income Account”? Huh? I must report the income and capital gains from the ISA on my US taxes so I need to know what us going on. I’m also paranoid that I’m getting hit with a hidden fee... Does anyone know what is going on?  Thanks!

Never mind; they answered.  As dividend income arises, they say it is in your “Income Account”.  You are then able to invest or withdraw it when they move it to your “Capital Account”.  Why there is a delay between the dividend payment and access to the money is unclear.

Why are you bothering with an ISA if you're a US taxpayer?

Why I have an ISA:  Although I’m subject to US tax, I live in the UK am also taxed by HMRC. I have some of my investments in the UK to provide currency and geographical diversification. UK and EU companies also provide very high dividend yields and these are “qualified dividends” for US taxation. In that regard, my ISA consists of stodgy UK insurance and financial companies (LGEN, AV, DL) along with other UK “blue chip” stocks (RIO) and utilities. i  got absolutely hammered in thd covid-19 crash and has hardly recovered. My US portfolio (tech ETF heavy QQQ, VUG, VGT, TSLA, AMD...) has roared back to 95% of its pre-crash value. So far, the ISA has been terrible as I set it just before the crash.. Still, I think many UK stocks are extremely undervalued (at least compared to the US market) and even more so now. So, I’m betting that the ISA will pay off in the long run. We’ll see.
