Check residence nil-rate band eligibility and amount (England & Wales 2025/26): up to £175,000 per person where a home you own (or owned) passes to direct descendants, doubled for a married couple / civil partners, plus a late spouse's transferred allowance — capped at the home's value and tapered by £1 for every £2 the estate exceeds £2m. Illustrative check with plain-English reasons.
