About the Inheritance Tax Calculator

The first £325,000 of an estate is tax-free (nil-rate band). If a home goes to direct descendants, the residence nil-rate band adds up to £175,000, tapered by £1 for every £2 the estate exceeds £2 million. Unused allowances pass to a surviving spouse or civil partner, so a couple can leave up to £1 million tax-free. Both bands are frozen until April 2031.

Tax above the allowances is 40%, or 36% if at least 10% of the net estate goes to charity. From April 2027 most unused pension pots will count toward the estate.

The formula

IHT = (estate − exempt gifts − £325,000 − RNRB) × 40%

Worked example

  2. Formula: IHT = (estate − exempt gifts − £325,000 − RNRB) × 40%
