Tout savoir sur IHT Residence Nil Rate Band Calculator
📋Présentation+
Computes IHT (2025/26) combining the £325,000 nil rate band and the £175,000 residence nil rate band when a home passes to direct descendants — capped at the home value, tapered £1 per £2 above a £2,000,000 estate — plus transferred allowances from a deceased spouse and the reduced 36% rate when at least 10% of the net estate goes to charity.
💡 Bonnes pratiques
- A widow or widower can inherit up to 100% of both bands — up to £1,000,000 of combined allowances.
- The RNRB only works if the home (or a share) passes to direct descendants — leaving it into some trusts loses it.
- Leaving 10% of the net estate to charity cuts the IHT rate on the rest from 40% to 36%.
🔢 Exemple concret
£800,000 estate with a £400,000 home left to the children: £325,000 NRB + £175,000 RNRB = £500,000 of allowances — IHT of 40% on £300,000 = £120,000 (15% effective).
