UK Tax Questions? Ask a UK Tax Advisor for answers ASAP
Hello, I am Keith, one of the experts on Just Answer, and pleased to be able to help you with your question.
Firstly when you moved to Denmark did you complete a Form P85 and send it to the Inland Revenue as it was then? If you did not then you should do so immediately, but, of course, to HMRC. Fortunately there is no time limit as to its submission, it is available on the web and can be filed on line. On receipt HMRC will classify you as non resident. The form makes provision for any tax refund due on leaving the UK during part of a tax year.
You can claim your State Pension (SP) on line. The procedure you can find here:
Although you may be entitled to a SP you cannot reclaim any National Insurance contributions made in the past.
I do hope that you have found my reply of assistance.
