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?
If Forex gains/loss is taxed in your tax jurisdiction, you need to calculate it and report it. Luckily IB does that for you, if you choose the currency of your tax jurisdiction as base currency. Both direct FX trades and indirect = when you trade stocks in a different currency than the currency of your tax jurisdiction and keep an FX account in the different currency. Buy stocks = sell currency. Sell stocks = buy currency.
Where can I find these in IB? I only see direct FX transactions in my IB trading confirmations, so I've been creating these transactions in my calculations myself. Should I use flex queries to get these?
I am not a regular trader. If I throw them my koinly or cointracker report of 800 crypto transactions and my IB report of 250 transactions, would it work out within 200-300 quid and do they provide any guarantees on accuracy (assuming of course I have given them the right report)?
At the bottom of the Realized & Unrealized Performance Summary section. Here you see the end result. But you have to change your base currency to GBP first. Or you can draw a section called Forex P/L Detail and see the calculation line by line. Be prepared for many lines. 30,000 lines if your number of trades is for instance 8,000. IB uses FIFO as default. You have to make sure that the tax regulation in your jurisdiction uses the same principle.
I pay my taxes in a Euro country and have EUR as base country and those forex realized PnL in operations that didn´t involve EUR gave me quite some headache. Below is the reply I got from IB on the topic, which you might find useful, u can probably change EUR for GBP in your case. Note as well IB does show the PnL in its statements, but other brokers I have where no euros are used don´t, which might end up as an issue with local tax authorities. Frustrating as well that in a year like 2022 while my portfolio is way down I end up with significant realized gains because of forex (will realize some losses to end up with a 0 PnL but it´s still a hassle). "Kindly note, Tbill and US-T are denominated in USD and your current base currency is EUR.
