Frequently asked questions

Does the property have to be in the will for the RNRB to apply?

Not necessarily. If the property passes by survivorship (for example, a joint tenancy between spouses), the RNRB can still apply on the second death. What matters is that the property ultimately passes to direct descendants.

Can the RNRB apply if the deceased lived in rented accommodation at the time of death?

Only if they owned a residential property at some point and sold or downsized it after 8 July 2015. In that case, the downsizing addition may allow the RNRB to be claimed against other assets in the estate.

What if the home is left to a trust rather than directly to children?

It depends on the type of trust. Certain trusts — including immediate post-death interest trusts and bereaved minor's trusts — can qualify. Others do not. If the will creates a trust, check with a solicitor whether the RNRB still applies.

The estate is worth more than £2 million. Is the RNRB completely lost?

Not necessarily. The taper reduces the RNRB by £1 for every £2 over £2 million. So an estate worth £2.1 million would still have £125,000 of RNRB available. Only estates worth £2.35 million or more lose it entirely.

My parent left their home to me and my sibling equally. Do we both get the RNRB?

The RNRB applies to the estate, not to individual beneficiaries. The full RNRB (up to £175,000) is available to the estate as long as the property passes to direct descendants — it does not matter how many children inherit it.

The first spouse died years ago and we do not have their IHT paperwork. Can we still claim the transferred RNRB?

Yes, but you will need to reconstruct what you can. HMRC can sometimes access old records. A solicitor who specialises in probate can help you gather the evidence needed to support the claim.
