The Heritage Property Exemption for Inheritance Tax
What the law says
The Core Exemption — IHTA 1984, ss. 30–35A
A transfer of value is an exempt transfer to the extent that the value transferred is attributable to property that:
- Has been designated by the Treasury under s. 31 IHTA 1984; and
- An undertaking has been given by the appropriate person with respect to that property.
What property can be designated (s. 31 IHTA 1984)?
The Treasury may designate:
- (a) Any relevant object (e.g. picture, print, book, manuscript, work of art, scientific object) that is pre-eminent for its national, scientific, historic or artistic interest;
- (aa) Any collection or group of such objects that, taken as a whole, is pre-eminent for such interest;
- (b) Any land of outstanding scenic, historic or scientific interest;
- (c) Any building whose preservation warrants special steps by reason of its outstanding historic or architectural interest;
- (d) Any area of land essential for the protection of the character and amenities of such a building; and
- (e) Any object historically associated with such a building.
In determining whether an object or collection is pre-eminent, regard must be had to any significant association with a particular place.
The Undertakings Required (s. 31 IHTA 1984)
For objects/collections (s. 31(1)(a)/(aa)), the owner must undertake that:
- The property will be kept permanently in the UK (and only leave temporarily with Treasury approval); and
- Agreed steps for preservation and reasonable public access will be taken.
For other property (land, buildings, associated objects), the undertaking must cover maintenance, repair, preservation and reasonable public access.
Importantly, the steps agreed for securing reasonable access must ensure that access is not confined to access only where a prior appointment has been made.
Time Limit for Claims (s. 30(3BA) IHTA 1984)
A claim must be made no more than two years after the date of the transfer of value (or, for a potentially exempt transfer, the date of death), or within such longer period as HMRC may allow.
For potentially exempt transfers, no claim may be made until the transferor has died, and the exemption does not apply if the property was disposed of by sale between the date of transfer and the transferor's death.
Chargeable Events — When Tax Becomes Payable (s. 32 IHTA 1984)
The exemption is "conditional" because IHT becomes chargeable on the first occurrence of a chargeable event after the conditionally exempt transfer. Chargeable events include:
- Material breach of the undertaking (if the Treasury is satisfied the undertaking has not been observed in a material respect);
- Death of the person beneficially entitled to the property; or
- Disposal of the property, whether by sale, gift or otherwise.
However, a death or disposal is not a chargeable event if:
- The property is sold by private treaty (or given) to a body listed in Schedule 3 IHTA 1984 within three years of the death; or
- The disposal is itself a new conditionally exempt transfer (i.e. the new owner gives fresh undertakings).
Settled Property — ss. 78 & 79 IHTA 1984
- s. 78 IHTA 1984 provides exemption from exit charges on heritage property comprised in a relevant property settlement.
- s. 79 IHTA 1984 provides exemption from ten-yearly anniversary (TYA) charges. Following Finance Act 2015, trustees have up to two years from the date of the ten-year anniversary to make a claim for conditional exemption for anniversary charges arising on or after 18 November 2015. Once exempted, tax is not chargeable under s. 64 IHTA 1984 in relation to the property by reference to that or any subsequent ten-year anniversaries — until a chargeable event occurs.
HMRC guidance / practice
Purpose of the exemption
HMRC describes conditional exemption as being given to help ensure that items of national, artistic, historic or scientific interest are conserved and protected for the benefit of the nation as a whole. The provisions (IHTA84/ss. 30–35A and 78–79) are designed to encourage owners of important items to keep them in private ownership whilst caring for them and displaying them to the public.
Why it is called "conditional"
The exemption is described as conditional because there is normally a tax charge if the undertakings are materially broken. There is also a tax charge, normally, if the property is sold or disposed of otherwise than by sale without a replacement undertaking from the transferee.
The role of HMRC Heritage Section
All claims for conditional exemption and Offers in Lieu of Tax are handled by the Heritage Section in Nottingham. Caseworkers must refer any claim (whether within or outside the two-year time limit) or any question on taxation and the national heritage to Heritage for advice immediately.
A final IHT calculation on a trust charge cannot be raised until Heritage Section's advice has been received.
Heritage Maintenance Funds (HMFs)
Where a historic property is of sufficient historical significance, it may be "approved heritage property" and certain IHT advantages apply. The Heritage Section decides whether the property meets the threshold and, if so, issues a direction under paragraph 1, Schedule 4 IHTA 1984. Special income tax provisions also apply to HMFs under ITA 2007, Part 9, Chapter 10 (ss. 507–517).
CGT parallel
There is a similar exemption from Capital Gains Tax (CGT) for conditionally exempt heritage property.

A disposal of heritage assets, such as historic buildings or works of art, which meet certain conditions can qualify for exemption from Inheritance Tax (IHT). This is known as conditional exemption. The exemption is described as conditional because when the circumstances surrounding exempted assets change, usually when they are sold, IHT will often then be payable on the asset. Chargeable events in respect of heritage assets arise comparatively rarely. On most occasions the application of the re
