Family farms and family‑run businesses have won a significant legal breakthrough in their challenge to the Chancellor’s inheritance tax reforms, after the High Court agreed to fast‑track a judicial review into whether Rachel Reeves acted unlawfully when altering long‑standing reliefs. The reforms were unveiled in the 2024 Budget, when Ms Reeves confirmed that agricultural and family business assets would no longer receive full inheritance tax relief. Tax specialist Marvin Rust of Alvarez & Marsal, who is also involved in the case, criticised the way the reforms were introduced. Limiting long‑standing inheritance tax reliefs, he said, amounted to a major legislative shift that should not have been implemented without proper consultation. A ruling is expected later this year following the two‑day hearing, with potentially far‑reaching implications for future tax policy.
