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.

Will I be impacted by the IHT changes?

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)

Take 1 minute to complete our simple IHT calculator to find out how you could be impacted.

Please note: The calculator below has been updated following the Government’s announcement on 23 December stating that the level of the Agricultural and Business Property Relief’s threshold will be increased from £1m to £2.5m when it is introduced in April 2026.
