Who is the main user for election for foreign loss to be allowable loss?

Hi HMRC, I would like to know if the election for foreign loss (loss on disposals of non-UK asset such as foreign stock shares) to be allowable losses is "the right" of the remittance basis user. I am UK tax user and domiciled in the UK. I am still having some foreign stocks which arise some gain or loss after disposals. For self assessment tax return, am I eligible to claim or elect the foreign loss to be allowable loss? Also, I do not know which 3-letter code I should use for my above case? I am looking forward to receiving your expert advice. Thank you.

Hi,

If you are UK resident and domiciled, you cannot use the remittance basis as you are liable on your worldwide income and gains. For country codes, please refer to the guidance here:

Residence, remittance basis etc notes

Thank you.
