Inheritance tax (IHT) is a reserved tax, overseen by the UK Government.
Therefore, it is important to refer to the published HMT data and assessments, which are based on the most recent claims for agricultural property relief which suggest that most farms will be unaffected by the changes.
Further information can be found at What are the changes to agricultural property relief? - GOV.UK and Agricultural property relief and business property relief reforms - GOV.UK.
