I applied for a Halifax "Help to Buy" ISA (UK Government scheme). I was born in the USA (but have not been a resident since I was 4 years old, now 26 and my parents are British) so I entered that was my country of birth. It suggested I entered my TIN number (first time I heard about this number), but did not seem to require it and let me proceed without specifying.
Should I be concerned about the US Government trying to claw away some of my money? I've been considering renouncing my Citizenship as they seem to have horrible tax laws for non-residents. But then again I would like to apply for jobs in the USA in the next few years.
Need I worry? Thanks for any help :)
