Hi HMRC team, I have the same issue as described by 'Stressed Eric', in the above thread. I have been receiving RSU's from my employer, a US company, since 2018. I currently do not fill in a self assessment tax return, as I have historically assumed that my employer calculates the tax correctly, on my behalf. However, this is not the case - I am being double taxed, in exactly the same way, as 'Stressed Eric' has described. I have two questions: 1. I believe that I can claim the overpaid tax back, for the last 4 years, from what I have read. Can you please confirm if this is correct? 2. How do I initiate the process, to claim the overpaid tax back? Many thanks - appreciate your help.
