What this calculator does
This calculator estimates UK inheritance tax based on estate value and simplified nil-rate band assumptions.
How the formula works
Net estate is gross estate minus liabilities, plus chargeable gifts entered. We then subtract available nil-rate bands and apply 40% IHT to the taxable amount.
Important limitations
- Simplified model only: no taper relief or full gift timing rules.
- Residence nil-rate band has detailed conditions not fully modelled.
- No trust planning or business/agricultural relief modelling.
