Inheritance Tax Calculator

In October 2024, the government announced the most significant reforms to inheritance tax (IHT) seen in a generation. The changes come into force from 6 April 2026 and could mean significant increases in IHT exposure for estates.

The new rules will impact those holding assets including:

  • Shares in an unlisted trading company valued at more than £1m;
  • An interest in a trading business or partnership valued at more than £1m;
  • Agricultural land, including farm buildings and farmhouses.
  • Pensions (from April 2027)
