How this is worked out
The nil-rate band of £325,000 plus any extra allowances you enter are deducted from the estate value, and 40% is charged on what is left.
Worked example
- Estate value £600,000
- Extra allowances £0
600,000 − 325,000 = 275,000, taxed at 40%
£110,000.00
Assumptions and limits
- Extra allowances are whatever you enter. The calculator does not test whether you qualify for the residence nil-rate band of up to £175,000, which needs a home passing to direct descendants and tapers away on estates above £2 million, or for a transferred allowance from a late spouse or civil partner.
- Gifts in the seven years before death, business and agricultural relief, trusts and the reduced 36% rate for large charitable gifts are not included.
- Anything passing to a spouse, civil partner or charity is normally exempt and should be left out of the estate value.
