For regular stock positions in cash accounts HMRC insist that selling and buying prices are calculated in GBP first before calculating profit.
My understanding for stock positions in margin accounts (for eg, a USD denominated stock) is that the USD profit is taken first and then converted to GBP for tax purposes. One question here is can I add interest charges in cost?
I usually trade on margin only if my cash account doesn't have enough settled cash, as a temporary measure. What I usually do is move the margin position into my cash account once cash is settled. In this case, would I have to consider the stock as having been sold in the margin account and bought back in the cash account (I don't think IB statements or flex queries reflect this)? Because, otherwise it would be impossible to calculate tax based on the rules above.
Another question here is with regard to Forex. HMRC appears to treat anything gained on anything other than GBP to be added to the total. So this means if I'm keeping money in USD and then using that USD to buy stock, and later on sell that stock, I would have to consider the disposal of USD in addition to the purchase of the stock, and the purchase of USD in addition to disposal of stock for Tax calculation and matching purposes (section 104, same-day, BnB, etc).
Yet another thing is that IB transacts in symbols like GBP.USD and EUR.USD for Forex transactions. I assume it's appropriate to consider these as the instruments for tax calculation when Forex is held on margin, and if not on margin, I have to take the buying and disposals as that of actual currency (i.e buying GBP.USD should be treated as selling dollars to get GBP as proceeds) when doing tax calc and matching?
Would/should the HMRC care about this level of detail about matching of forex trades (explicit and implicit) if the primary activity done on the accounts is stocks and options trading, and not Forex trading?
