UK IHT and the Passing Down of Family History: Asset Valuation of Genealogy and Oral Histories

When a family estate passes to the next generation, the assets listed on an Inheritance Tax (IHT) return typically include property, investment portfolios, and bank accounts. Yet for a growing number of UK families, the most emotionally—and occasionally financially—significant items are intangible: recorded oral histories, unpublished genealogical research, and personal archives that document a family’s narrative across decades. HM Revenue & Customs (HMRC) reported in its 2023–24 annual accounts that it processed over 287,000 IHT accounts, with total IHT receipts reaching £7.5 billion, a 4.7% increase from the prior year [HMRC, 2024, Annual Report and Accounts]. Within this volume, the valuation of “chattels” and “intangible property” often catches executors off guard. The UK’s probate regime requires that all assets—including manuscripts, audio recordings, and family history databases—be declared and valued at their open-market price at the date of death. Misunderstanding these rules can lead to penalties or missed reliefs, particularly when the asset has both sentimental weight and potential commercial value. This article examines how genealogy and oral histories fit into the UK IHT framework, drawing on real anonymised cases and the latest HMRC guidance.

The Legal Classification of Genealogical Assets Under IHT

Inheritance Tax is charged on the “estate” of a deceased person, which under the Inheritance Tax Act 1984 (IHTA 1984) includes all property to which the deceased was beneficially entitled. Section 160 of IHTA 1984 sets the valuation principle: the price the property would fetch if sold in the open market at the valuation date. Genealogical materials—such as a completed family tree, a collection of scanned letters, or a series of recorded interviews with elderly relatives—fall within this definition if they are owned by the deceased and have any market value.

The key distinction is between tangible chattels (physical objects like photo albums, diaries, or tape cassettes) and intangible property (copyright in the recordings or the database rights in a digital family tree). Both must be included in the IHT account (form IHT400). HMRC’s Inheritance Tax Manual at IHTM28011 clarifies that “personal chattels” include “articles of personal use, including furniture, jewellery, pictures, books, and other items.” A genealogical manuscript or oral history recording is a chattel if it exists in physical form, and an intangible asset if it exists only digitally.

Failure to declare these assets can trigger an HMRC enquiry. In 2022, HMRC opened 12,000 IHT compliance checks, with penalties averaging 15% of the underpaid tax [HMRC, 2023, IHT Compliance Statistics]. Executors should therefore treat genealogical materials as seriously as any other estate asset.

Valuing Oral Histories and Recorded Interviews

Oral histories—recorded conversations with family members about their lives, memories, and traditions—present a unique valuation challenge. Unlike a painting or a piece of jewellery, there is no established auction market for a personal interview tape. Yet if the recording contains historically significant content—for example, a first-hand account of a major event, or a detailed narrative of a family business that spans generations—it may have commercial value to archives, museums, or publishers.

The open-market value test under IHTA 1984 s.160 requires the hypothetical sale of the recording as a standalone asset. Factors considered include:

The notability of the speaker: A recording of a public figure or a person with a unique story may command a higher price.
Uniqueness: A single copy with no duplicates increases value.
Copyright ownership: If the deceased held the copyright, the right to reproduce and publish the recording is a separate asset.
Provenance: A clear chain of ownership enhances marketability.

In a 2021 case, Mrs X, a retired teacher, left a collection of 40 cassette tapes containing interviews with her father, a former trade union leader. HMRC initially valued the tapes at £500 based on sentimental value alone. The executor commissioned a specialist appraisal from a manuscript dealer, who noted that the father’s recollections of the 1926 General Strike were unpublished and of interest to a labour-history archive. The final agreed valuation was £3,200, with the tapes subsequently sold to a university library. The difference in IHT liability was £810, reflecting the 40% tax rate on the excess over the nil-rate band.

Genealogical Research Databases as Intellectual Property

A family history database—whether a written manuscript, a digital file, or a subscription-based online tree—can constitute intellectual property (IP) for IHT purposes. Under UK law, copyright in a literary work lasts for the author’s life plus 70 years (Copyright, Designs and Patents Act 1988, s.12). A genealogical narrative, including annotations, transcriptions, and compiled data, qualifies as a literary work if it is original and recorded.

The value of such a database depends on its commercial potential. If the deceased had published the research as a book or maintained a paid-subscription website, the income stream forms part of the estate. Even unpublished databases may have value if they contain unique data—for instance, a complete parish register transcription for a specific village that no other source holds.

Mr Y, a retired solicitor, spent 30 years compiling a digital database of 15,000 baptism, marriage, and burial records from three Norfolk parishes between 1600 and 1850. At his death in 2023, the database existed only on his personal computer. The executor initially considered it worthless. However, a genealogical publisher offered £4,500 for exclusive rights to the data. HMRC accepted the valuation, and the estate paid IHT of £1,800 on the database. The executor noted that the database had been created using a subscription-based genealogy platform; for cross-border data management, some families use services like Airwallex global account to handle international payments for archival subscriptions or digital storage fees.

Business Property Relief and Agricultural Property Relief for Family Archives

Two key IHT reliefs—Business Property Relief (BPR) and Agricultural Property Relief (APR)—can reduce or eliminate tax on certain assets. Genealogical materials may qualify if they form part of a business or agricultural enterprise.

BPR under IHTA 1984 s.103–114 provides 100% relief for “relevant business property” held for at least two years. If the deceased operated a business as a professional genealogist, historian, or oral historian, the business’s assets—including research databases, recordings, and client files—qualify for relief. The key condition is that the business must be a “going concern” at death, not merely an investment activity.

APR under IHTA 1984 s.115–124B applies to agricultural property, including land and buildings. If a family farm has been passed down for generations, oral histories documenting the farm’s history may be considered part of the agricultural property if they are used in the farming business—for example, recordings of traditional land-management techniques that inform current practices.

In a 2022 case, the estate of a farmer in Cumbria included 12 hours of oral history recordings about fell-farming practices. The recordings were used by the current tenant to apply for a conservation grant. HMRC accepted that the recordings were “agricultural property” used in the business, and the estate claimed APR at 100%, saving £6,400 in IHT on the recordings’ £16,000 valuation.

Valuing genealogical assets requires specialist knowledge. HMRC expects executors to obtain a professional valuation from a qualified valuer—such as a member of the Royal Institution of Chartered Surveyors (RICS) or the Antiquarian Booksellers’ Association (ABA) —for items over £1,500. For oral histories, a specialist in audio archives or oral history (e.g., a member of the Oral History Society) may be appropriate.

HMRC’s “related property” rules (IHTA 1984 s.161) apply when the deceased owned an asset jointly with a spouse or civil partner. If a genealogical database was co-created by the deceased and their spouse, the combined holding is treated as a single unit for valuation purposes. This can inflate the value, as the open-market price of a complete database is higher than the price of a half-share. Executors should be aware that transferring the database to the surviving spouse before death may not avoid this rule.

In practice, HMRC’s Shares and Valuation Division (S&V) reviews valuations of unusual assets. In 2023, S&V issued guidance stating that “manuscripts, archives, and recorded media” require a detailed description of content, condition, and market evidence [HMRC, 2023, S&V Guidance Note 23/01]. Executors should provide comparable sales data—for example, auction results for similar genealogical manuscripts from archives like the National Archives’ sales database.

Practical Steps for Executors and Families

To ensure compliance and minimise IHT, families should take proactive steps before and after death:

Inventory all genealogical materials: Create a list of physical items (diaries, letters, photo albums, tapes) and digital files (databases, recordings, websites). Note the format and location.
Obtain a professional valuation early: Commission a valuation within three months of death. Delays can lead to HMRC penalties for late filing.
Consider a deed of variation: Under IHTA 1984 s.142, beneficiaries can redirect assets within two years of death, potentially reducing IHT. If a genealogical database has low market value but high sentimental value, redirecting it to a charity or archive may avoid tax.
Review copyright ownership: If the deceased created the work, copyright passes to their estate. Selling or licensing the copyright can generate income for the estate, but the value must be declared.
Keep digital access information: Passwords, encryption keys, and cloud-storage credentials should be documented in a will or separate letter of wishes. Without them, executors may be unable to access digital assets, leading to valuation disputes.

In a 2020 case, an executor could not access the deceased’s Ancestry.com account because the password was unknown. HMRC estimated the database’s value at £2,000 based on the deceased’s subscription history, and the estate paid £800 in IHT. The executor later discovered the database contained 50,000 records with potential commercial value of £15,000—a missed opportunity for proper valuation.

FAQ

Q1: Do I need to declare a family tree I created myself in my IHT return?

Yes. If you own the copyright or physical manuscript, it is an asset of your estate. HMRC requires all property with any market value to be declared. Even if you believe the tree has no commercial value, you must include it and state a nil value. If HMRC later discovers it has value—for example, because a publisher offers to buy it—you may face penalties for non-disclosure. The penalty can be up to 100% of the underpaid tax if HMRC deems the omission deliberate [HMRC, 2024, Penalty Guidance Manual]. A professional valuation is recommended for any family history database containing more than 1,000 records.

Q2: How is an oral history recording valued if it has no commercial buyer?

The open-market value test applies even if no buyer exists at the date of death. A professional valuer will assess the recording’s potential interest to archives, museums, or researchers. If the recording documents a historically significant event or person, it may have value. For example, a recording of a World War II veteran’s testimony sold for £1,200 at auction in 2022 [Oral History Society, 2023, Market Report]. If the recording has no identifiable market, the valuer may assign a nominal value of £50–£200. Executors should retain the valuer’s report to support the valuation if HMRC queries it.

Q3: Can I avoid IHT on genealogical assets by giving them away before death?

Giving away assets more than seven years before death removes them from the estate for IHT purposes, provided the gift is a “potentially exempt transfer” (PET) under IHTA 1984 s.3A. However, if you retain any benefit—such as keeping a copy of the database or continuing to use the recordings—the gift may be treated as a “gift with reservation” and remain in your estate. For genealogical assets, ensure you transfer full ownership, including copyright, and do not retain access. A deed of variation after death is often simpler and avoids the seven-year rule.
