What this calculator does not cover
This calculator is intentionally cautious and simplified. It does not attempt to deal with all reliefs, exemptions or complex estate scenarios.
- Business Property Relief and Agricultural Property Relief
- Spouse or charity exemptions
- Trust-specific IHT rules
- Foreign domicile / excluded property issues
- Detailed residence nil-rate band conditions
- Reduced 36% charity rate planning
For planning that is actually actionable, the numbers should be reviewed in the context of your wider estate, gifting history and available reliefs.
Next step
Use the estimate as a starting point — not the final answer.
We can help you assess gifting, trust planning, reliefs, life cover and practical ways to reduce exposure.
