Terminology explained

Residence Nil Rate Band (RNRB)

Available since 6 April 2017, the RNRB adds an additional threshold when a primary residence or its sale proceeds are left to direct descendants. It complements the standard NRB but reduces for estates exceeding £2 million and may involve complex calculations for downsized homes or changes in residence. The RNRB as at 2024/25 is £175,000 per person.

Nil Rate Band (NRB)

The Nil Rate Band is the threshold up to which no IHT is charged on an individual's estate, set at £325,000 for 2024/25. Estates valued up to this amount are taxed at 0% IHT, while the excess is taxed at 40%.

Spousal Exemption

Spousal Exemption from Inheritance Tax (IHT) covers all transfers between spouses or civil partners, whether during lifetime or upon death, provided they are UK-domiciled or deemed domiciled. This exemption ensures no IHT is payable on these transfers.

Scenario background

Greg

Ginny

‍

Greg and Ginny are husband and wife who own £200k of potentially Business Relief (BR) qualifying assets each.

They also have a combined estate collectively worth £2.7 million, including the potentially BR qualifying assets.

Scenario 1

• Greg dies leaving all of his assets, including the potentially BR qualifying assets to Ginny.
• Ginny subsequently dies and leaves all her assets to their children.
• Greg dies having owned BR assets for two years.
• Ginny dies one year later (owning BR assets for two years).

Greg’s IHT position

Asset:

£200k BR Assets

Tax Payable:

Nil

Asset:

Remaining Estate

Tax Payable:

Nil

Greg’s whole estate will be IHT exempt due to the Spousal Exemption.

‍

Ginny’s IHT position

Asset:

£400k BR Assets

Tax Payable:

Nil

Asset:

Remaining Estate

Tax Payable:

£660,000

Ginny is eligible for BR, meeting the qualifying criteria on her BR assets. Ginny will receive a Nil Rate Band (NRB) of £650,000 being her own and Greg’s transferred Nil Rate Band (NRB).

However, due to Ginny’s estate exceeding the £2.7m threshold for the Residential Nil Rate Band (RNRB) Ginny will not receive the RNRB exemption.

Scenario 2

• Greg dies leaving his BR assets to his children, together with cash of £325k. The remainder of the estate is left to Ginny.
• Ginny subsequently dies and leaves all of her estate including her BR assets and the family home to her children.
• Greg dies having owned BR assets for two years.
• Ginny dies one year later (owning BR assets for two years).

Greg’s IHT position

Greg’s whole estate will be IHT exempt due to the Spousal Exemption.

‍

Ginny’s IHT position

Asset:

200k BR Assets

Tax Payable:

Nil

Asset:

Remaining Estate

Tax Payable:

£555,000

Ginny is eligible for BR, meeting the qualifying criteria on her BR assets. Ginny is able to utilise her own NRB.

As well as inheriting Greg’s RNRB she also has her own RNRB which has to be tapered slightly. These exemptions reduce her IHT exposure.

Takeaway

The two examples above show how the allocation of BR assets on death can impact on an individual’s wider entitlement to statutory IHT reliefs and exemption (and therefore their overall IHT position).
