This HMRC calculator has been updated to include the residence nil rate band (RNRB) for Inheritance Tax (IHT).

Charities and advisors are reminded that a reduced rate of IHT applies where 10 per cent or more of a deceased’s net estate (after deducting IHT exemptions, reliefs and the nil-rate band) is left to charity. In those cases the current 40 per cent rate will be reduced to 36 per cent. Some commentators have recently speculated that the amount of inheritance tax (IHT) saved by leaving money to charity will reach almost record £900m when the next set of charity tax statistics are published.
