I am rather puzzled by this matter. Given the complexity and sometimes controversial nature of cryptocurrencies, it seems plausible that HMRC, being a tax and revenue authority, would want to stay up-to-date on any transactions that might have tax implications. However, Binance, being a leading cryptocurrency exchange, would presumably have its own set of regulations and compliances to adhere to. So, does Binance indeed contact HMRC to ensure compliance with tax regulations? Or is there another layer of intermediaries or authorities involved? This question is particularly relevant given the recent surge in popularity of cryptocurrencies and the need for clarity on tax implications.
