Hi, this is my first time posting so apologies in advance if this topic has already been covered, pls copy the link if a discussion already exists.
I'm a British national, lived overseas for 30+ years and a non-tax resident for as many years. I have no UK property nor any other income apart from a private work pension which I started to draw down. I have been paying Emergency Tax for 7 years. my questions are: a) how far back (years) can i claim a refund for? b) can anyone see any pitfalls in asking HMRC for my Tax Code to be re-assessed? would i be opening up a can of worms with HMRC in relation to disclosing overseas assets? I own properties in Thailand. Advice welcome.
