How the Residence Nil-Rate Band Works
and How to Avoid Losing it
The residence nil-rate band (RNRB) is one of the most valuable inheritance tax allowances available to UK families. When combined with the standard nil rate band and the transferable nil rate band, it can allow couples to pass up to £1 million to their children free of inheritance tax.
However, many estates lose this allowance due to technical rules and misunderstandings about how it operates.
Residence Nil-Rate Band
What is Residence Nil-Rate Band?
The residence nil-rate band is an additional inheritance tax allowance available when a main residence is passed to direct descendants, such as children or grandchildren. The allowance is currently £175,000 per person. When combined for a married couple, the total allowance may reach £350,000.
When is the Residence Nil-Rate Band Reduced?
The allowance can be reduced in certain situations, including when:
• The estate exceeds £2 million
• The property is not left to direct descendants
• Estate planning structures are not set up correctly
Downsizing Rules
If someone sells or downsizes their property before death, the residence nil rate band may still apply through downsizing relief. This allows families to claim the allowance even if the original home has been sold, provided certain conditions are met.
Why Professional Advice Matters
The rules around the residence nil rate band are complex. Trusts, large estates, and family circumstances can all affect eligibility. Careful planning ensures that families do not lose valuable allowances unnecessarily.
