Understanding the Residence Nil Rate Band (RNRB)
The Residence Nil Rate Band (RNRB) is an additional inheritance tax allowance of £175,000 available when you leave your main residence to direct descendants. Combined with the standard nil rate band, a single person can pass £500,000 free of IHT, while couples can protect up to £1,000,000.
Key RNRB Facts for 2024/25
- Current RNRB: £175,000 per person
- Transferable: unused RNRB passes to surviving spouse or civil partner
- Combined (couple): up to £350,000 RNRB + £650,000 NRB = £1,000,000 total
- Eligibility: main residence must pass to children, grandchildren, or other direct descendants
- Taper: RNRB reduces by £1 for every £2 above the £2,000,000 estate threshold
