In January I will be moving to Japan to work for a Japanese registered company (it is not obliged to pay UK taxes). Once there I will be subject to Japanese tax. However, I am receiving conflicting advice about what I need to do to let HMRC know of this change before I leave.
I am aware I need to provide a P85 form, but am unsure whether I must also do a self-assessment tax return (I have no unearned income in the Uk but will be paid in different currencies in the same tax year). I’m also unsure how to apply for a Nil Tax code so I am not put on emergency tax - is this something I do or my employer?
I would appreciate any advice.
