IHT Calculator

Your heirs might potentially have to pay inheritance tax after your death depending on the value of your estate. It is a confusing subject so we have put together a calculator, to provide you with an estimate of whether you could be liable or not and to give a rough estimate of how much. For further details or guidance, get in touch with us today to see how we can help.


Will you be leaving your property to your direct descendants?

What is your marital status?

If married or in a civil partnership, assets left to the surviving partner after the first death are generally exempt from IHT. Their unused allowance is then added to the surviving partners allowance upon second death.

Therefore, if wanting to calculate your IHT liability as a couple for when you have both passed away, please combine and enter the total for both of you for each question

This calculation will be based on the assumption that all assets were left to the surviving partner and the deceased partner did not use any of their nil band rate allowance.




This calculator is only to be used to gain an estimate. The information shouldn't be construed as legal or tax advice. Tax benefits may vary as a result of statutory change and their value will depend on individual circumstances. An advisor should always be consulted. All figures correct as of July 2022.

Please note:

  • Calculations for couples assume that all assets are left to survivor on first death, so form part of survivor’s estate on second death.
  • IHT liability for couples assumes all properties are owned as joint tenants for RNRB purposes.
  • No account is taken of reduced rates of inheritance tax (e.g. where some or all of estate may be left to charities, for national purposes etc).
  • Any lifetime gifts that may have been made that reduce the available nil rate band are not taken into account.
  • Calculations for couples assume they are married/ civil partners and that both are UK domiciles.
  • The value of any pension funds and other death benefits payable on death do not form part of the estate(s).
  • This calculator does not factor in the taper on the property allowance, which falls on estates worth more than £2m.
  • Some investments are not subject to inheritance in some circumstances, such as AIM shares. Speak to a financial adviser for more information.
