Hi, I recently came to UK on 5-years skilled worker visa. I worked in Bahrain for 18 years before that and have saved up some money over the years (from employment/salary and investments in funds). I have redeemed all my investments before landing in the UK. My question is that if I bring this money to UK, will it be taxed? And if there is any time limit to bring this money in? Also, what is the procedure and how do I declare it? Thanks.
