I am a US citizen but UK resident. My grandparent died and his money and assets were put in a trust and I was one of the beneficiaries. He and all of the trustees have never lived in the UK and I did not live in the UK at the time of his death. I have since received inheritance from his monetary estate in the form of several small payments (less than £10k) and one lump sum payment, all to a US account during my UK residency. I have not transferred that money to the UK or used it it all. Am I still liable to pay UK tax on this money or is it classed as inheritance? If I were to transfer it to the UK for a deposit on a property would it then be taxed?
