I have been working here in the UK since October 2003, but since I am getting paid from my US employer (who will be charging back my UK employer sometime in the near future), I have not as of yet had to get an NIN number. But should I get one?
I am assuming I will have to pay UK taxes for the 2nd half of the 2003/04 UK tax year, and I am not sure if they will require me to get an NIN number either.
Thanks
