Families have been warned that some estates face potential inheritance tax bills of more than 90% due to reforms effective from April 2027. Unused pension pots will be included in the inheritance tax calculation, significantly increasing tax liabilities. NFU Mutual's Sean McCann said the changes "will mean some families will be hit with a triple tax blow," through a combination of inheritance tax on pensions, loss of a tax break on family homes and additional income tax if the person who passes away is over 75.
