Mosbah-Fadi Houssami

Hello. I never received my UTR after filling the self-assessment. I sent a letter to HMRC and they said that they need my National Insurance Number to send the UTR again. The problem is that I am not a UK citizen and I live abroad, so I don’t have an address in the UK nor a National Insurance Number. I invested in a property in the UK, and I need to pay my taxes. What to do ??
