Inheritance Tax estate estimate
Enter the estate’s value after debts, then add the exemptions and unused allowances that apply.
Before you start: The estimate uses the standard 40% rate for one estate. Check how much of each allowance is available, including any previous use. The calculator cannot decide whether allowances can be transferred or residence relief applies. It leaves out lifetime gifts, the charity reduced rate, trusts and business or agricultural relief. Residence relief is reduced using the net estate before exemptions.
