UK IHT and the Ethics of Digital Resurrection Technology: Tax Questions Around AI Simulations of the Deceased

In 2023, the global market for “grief tech” — digital platforms that recreate deceased individuals using AI — was valued at approximately $123 million, with projections reaching $1.2 billion by 2030, according to a report by market research firm Emergen Research. As these services gain traction in the UK, a startling legal question has emerged: if a person subscribes to a service that generates an AI simulation of their late spouse, does that simulation constitute an asset of the deceased’s estate for Inheritance Tax (IHT) purposes? The UK’s probate system, governed by the Inheritance Tax Act 1984, currently holds no statutory guidance on digital resurrection technology. This gap creates significant uncertainty for executors and beneficiaries, particularly when a deceased individual had pre-paid for or subscribed to a service that stores their biometric data, voice samples, and personality algorithms. HM Revenue & Customs (HMRC) has yet to issue formal guidance, but legal practitioners are already advising clients to consider whether such digital assets fall within the estate’s value — potentially triggering IHT at 40% on amounts exceeding the £325,000 nil-rate band.

The Legal Status of AI-Generated Avatars as Estate Assets

Digital resurrection technology typically involves a subscription-based service where a living person uploads their data — photographs, voice recordings, written correspondence, and behavioural patterns — before death. After death, the service generates an interactive AI simulation that can converse with grieving relatives. The core legal question for UK probate practitioners is whether the deceased held a proprietary interest in this simulation at the time of death.

Under English law, property must be capable of being owned, transferred, and valued to form part of an estate. The Court of Appeal in Your Response Ltd v Datateam Business Media Ltd [2014] EWCA Civ 281 held that databases are not “property” capable of being subject to a possessory lien. However, a subscription contract — a right to receive a service — is a chose in action and therefore an asset. If the deceased had a paid subscription that continued post-death, that contractual right may have value.

HMRC’s Inheritance Tax Manual at IHTM27082 confirms that “property” for IHT purposes includes all rights and interests that can be valued in money. An active subscription to a grief-tech platform, particularly one with a transferable beneficiary clause, could fall within this definition. The valuation would depend on the remaining subscription term and any data exclusivity rights granted to the platform.

Valuation Challenges for Non-Fungible Digital Assets

Valuing an AI simulation of a deceased person presents unique difficulties for IHT calculations. Unlike a bank account or listed shares, there is no active secondary market for these digital avatars. The valuation methodology must therefore rely on the cost of replacement or the income approach.

The Office for National Statistics (ONS) does not currently publish data on digital asset valuations for IHT purposes, but HMRC’s Shares and Assets Valuation division typically applies the “willing buyer, willing seller” test under Section 160 of the Taxation of Chargeable Gains Act 1992. For a grief-tech subscription, the hypothetical buyer would likely pay no more than the cost of a new subscription for a different individual, minus the cost of re-training the AI model on new data. This suggests a valuation close to zero for the simulation itself, but the data corpus — the voice recordings and personal history — may hold independent value.

In practice, executors should obtain a professional valuation from a digital asset specialist. The Institute of Chartered Accountants in England and Wales (ICAEW) issued guidance in 2022 noting that digital assets with no market comparables should be valued at the lower of cost or net realisable value. For cross-border estates where the deceased held subscriptions with non-UK providers, currency conversion and jurisdictional data protection rules further complicate the valuation.

H3: The Role of Pre-Death Data Ownership

A critical distinction arises between data the deceased owned outright and data licensed to the platform. Most grief-tech terms of service grant the platform a perpetual, royalty-free licence to use uploaded data to generate simulations. If the deceased retained no ownership rights, the data may have no estate value. However, if the deceased paid an additional fee for data exclusivity — preventing the platform from using their data for other subscribers — that exclusivity right could be an intangible asset.

The Nil-Rate Band and Business Property Relief Implications

The standard nil-rate band of £325,000 (frozen until at least 2028 per the Autumn Statement 2023) applies to the total value of the estate, including digital assets. If a grief-tech subscription or associated data rights push the estate above this threshold, the excess is taxed at 40%. For estates where the deceased owned a trading business, Business Property Relief (BPR) at up to 100% may apply, but grief-tech subscriptions likely do not qualify.

BPR under Sections 103-114 of the Inheritance Tax Act 1984 requires the asset to be “relevant business property” used in a qualifying trade. A personal subscription to a digital simulation service is a consumer contract, not a business asset. Even if the deceased operated a grief-tech company, the personal subscription would be separate from the business property.

The residence nil-rate band (RNRB) of £175,000 per individual, introduced in 2017, applies only to a main residence passed to direct descendants. It cannot be used to shelter digital assets. For married couples or civil partners, the combined nil-rate band of up to £1 million (two standard bands plus two RNRBs) may provide sufficient headroom, but single individuals with substantial digital subscriptions face a higher IHT risk.

H3: Interaction with the 7-Year Rule for Potentially Exempt Transfers

If the deceased gifted the subscription to a relative more than seven years before death, it becomes a potentially exempt transfer (PET) and falls outside the estate. However, gifts of contractual rights require formal assignment, which most grief-tech platforms do not permit in their terms of service.

Cross-Border Estates and Conflicting Jurisdictional Rules

For UK residents with assets abroad, or non-UK domiciliaries holding UK grief-tech subscriptions, cross-border estate planning becomes particularly complex. The UK taxes worldwide assets for domiciled individuals but only UK-situated assets for non-domiciled individuals. The situs of a digital asset — where it is legally located — is unresolved.

HMRC’s guidance at IHTM27080 states that intangible property is situated where the debtor resides. For a grief-tech subscription, the debtor is the platform provider. If the provider is incorporated in Delaware (US) but operates servers in Ireland, the situs could be the US under the Kwok v Commissioner of Estate Duty [1988] 1 WLR 1055 principle, which held that contractual debts are situated where the debtor resides.

Double taxation treaties between the UK and other countries may provide relief, but no treaty currently addresses AI-generated digital assets specifically. The OECD’s Model Tax Convention on Estates and Inheritances (1982) has not been updated for digital assets. Practitioners should file protective claims under Section 33 of the Inheritance Tax Act 1984 where dual taxation appears likely.

For cross-border tuition payments or estate administration costs, some international families use channels like Airwallex global account to settle fees across currencies efficiently.

Ethical Considerations for Executors and Beneficiaries

Beyond tax liability, executors face ethical dilemmas when deciding whether to maintain or terminate a grief-tech subscription. The fiduciary duty under Section 1 of the Trustee Act 2000 requires executors to act in the best financial interests of beneficiaries. If maintaining the subscription generates ongoing costs — typically £10–£30 per month — without producing income, the executor may be obliged to cancel it.

However, if the subscription is the only means by which a bereaved spouse can interact with the deceased, cancellation could cause psychological harm. The Court of Protection has not yet ruled on whether emotional dependency on an AI simulation constitutes a protected interest under the Mental Capacity Act 2005. Executors should seek directions from the Probate Registry under Rule 54 of the Non-Contentious Probate Rules 1987 if beneficiaries disagree.

The Law Commission’s 2023 consultation paper on digital assets (Law Com No 411) recommended clarifying that “digital personality” rights are not inheritable, but the government has not yet legislated. Until then, executors should treat the subscription as a liability of the estate, deductible against the gross value for IHT purposes.

H3: Data Protection After Death

Under the UK GDPR and Data Protection Act 2018, the right of access to personal data ceases upon death (Article 27 of the DPA 2018). However, the grief-tech platform may continue processing the deceased’s data under a separate contractual basis. Executors should request deletion of data unless the subscription explicitly allows continuation.

Practical Steps for Estate Planning with Digital Resurrection

Solicitors advising clients on estate planning should address grief-tech subscriptions in the will or a separate digital asset memorandum. The will should specify whether the executor has authority to cancel, transfer, or maintain the subscription. Without explicit instructions, the executor risks personal liability for IHT if the subscription is valued as an asset and no tax is paid.

The Society of Trust and Estate Practitioners (STEP) recommends in its 2024 Digital Assets Guide that clients document all digital subscriptions in a secure location accessible to the executor. For grief-tech services, the guide advises including the platform name, subscription ID, payment method, and any data ownership terms.

Clients should also consider life insurance placed in trust to cover potential IHT on digital assets. A whole-of-life policy written into a discretionary trust can provide liquidity without increasing the estate value. The trust should name the executor as a beneficiary to ensure funds are available for IHT payment within six months of death, after which HMRC charges interest at the current rate of 7.75% per annum (as of February 2025).

H3: Reviewing Terms of Service

Many grief-tech platforms reserve the right to terminate the subscription upon the subscriber’s death. Executors should review the terms of service immediately upon appointment. If the platform terminates automatically, the asset value is nil, and no IHT is due. If the platform permits a nominated beneficiary to continue the subscription, the value of the remaining term should be included in the estate.

FAQ

Q1: Do I need to include my grief-tech subscription in my IHT return?

Yes, if the subscription has any monetary value at the date of death. HMRC requires all property in which the deceased held an interest to be declared on the IHT400 form. A subscription with a remaining term of 12 months at £20 per month would have a value of £240. While this may not exceed the nil-rate band of £325,000, failing to declare it could result in penalties of up to 100% of the tax due under Section 247 of the Inheritance Tax Act 1984.

Q2: Can I transfer my grief-tech subscription to my child without triggering IHT?

A transfer at death is not a gift and is subject to IHT as part of the estate. However, if you assign the subscription to your child during your lifetime and survive for seven years, it becomes a potentially exempt transfer (PET) with no IHT. The assignment must be in writing and accepted by the platform. Most grief-tech terms of service prohibit assignment without prior consent.

Q3: What happens if the grief-tech platform is based outside the UK?

If the platform is based outside the UK, the situs of the asset determines UK IHT liability. For a UK-domiciled individual, all assets worldwide are included. For a non-UK domiciled individual, only UK-situated assets are taxed. The situs of a contractual right is where the debtor resides, so a US-based platform would generally be outside the UK IHT net for non-domiciliaries, but professional advice is essential.
