I own many stocks of the same company. I sell some but not all of them. I am wondering if it is possible to calculate the cost basis of a sale by looking at specific stocks' purchase price, rather than forming a sharepool, to determine the cost basis. To illustrate: Bought 5 shares at $10 Bought 5 shares at $20 My broker tracks these shares individually, so I can choose to sell 3 of the ones I bought for $10. Given I know which specific shares I sold, can I use a cost basis of $10?

If the stocks were acquired as part of an employee equity compensation program that grants RSUs, where stocks are granted and then vest at a later date, does this change the answer? If not, is the purchase price (and therefore cost basis) that of the grant or vest date? Thank you!

I acquired stock in a single company prior to moving to the UK. Now, as a UK resident, I sold some of that stock. What is the cost basis I should use when calculating the sharepool value? A concrete example: I purchased 5 stock units in Company A for $10 each prior to moving to the UK. 1) I read somewhere that the cost basis is set to 0 for stocks acquired while not a UK tax resident. Is that correct, or should I use the purchase price ($10)? 2) If I use the purchase price, what exchange rate should I use - that of the date of acquisition or of sale? Thank you!
