UK IHT on Digital Assets: How to Value and Report Cryptocurrency and Online Accounts

HM Revenue & Customs reported in its 2023/24 annual inheritance tax (IHT) account that total IHT receipts reached £7.5 billion, a rise of £400 million from the previous year, driven partly by frozen nil‑rate bands and rising asset values including digital holdings. A separate 2024 survey by the Law Society of England and Wales found that 62% of solicitors now encounter digital assets—cryptocurrency, online business accounts, or social media profiles—in probate matters at least once per quarter. Yet the vast majority of wills drafted before 2020 contain no specific provision for digital property, creating a valuation and reporting gap that HMRC is increasingly scrutinising. For executors and beneficiaries, the challenge is twofold: establishing a defensible market value for volatile crypto holdings, and identifying all online accounts that may constitute part of the estate. This article sets out the current UK framework for valuing and reporting digital assets for IHT purposes, using anonymised case studies and referencing official HMRC guidance and the Office of Tax Simplification’s 2022 review of IHT administration.

The Legal Definition of Digital Assets in an Estate

Digital assets in UK probate law are not a single category but a spectrum. The Law Commission’s 2022 consultation paper on digital assets defined them as any digital record that is not a mere copy of a paper document and that has independent economic or sentimental value. For IHT purposes, HMRC guidance (IHTM27000 series) distinguishes between:

Cryptocurrency and tokens (e.g. Bitcoin, Ether, NFTs) — treated as chargeable assets subject to IHT at 40% above the nil‑rate band.
Online accounts with monetary value — including PayPal balances, e‑commerce store inventories, freelance platform earnings held in digital wallets.
Accounts with no direct monetary value — social media profiles, email archives, cloud storage — which may still require reporting if they hold intellectual property or digital copyrights.

The key distinction for executors is whether the asset is “property” capable of being owned and transferred. In AA v Persons Unknown [2019] EWHC 3556 (Comm), the High Court confirmed that cryptocurrency is property under English law, settling earlier uncertainty. This ruling means crypto assets must be valued as at the date of death and included in the IHT account (form IHT400). Failure to report them can trigger HMRC penalties of up to 100% of the tax due, plus interest.

Valuing Cryptocurrency at the Date of Death

The valuation date for IHT is the date of death, not the date of probate or sale. HMRC’s IHTM27150 states that assets must be valued at “the price which the property might reasonably be expected to fetch if sold in the open market” immediately before death. For volatile assets like Bitcoin, this creates a practical problem: the value on the death date may differ dramatically from the value when the executor gains access to the exchange account weeks or months later.

HMRC accepts a single, reliable price source as long as the executor can document it. The preferred approach is to use the daily closing price from a major, regulated exchange (e.g. Coinbase, Kraken, or Gemini) on the exact date of death. For a portfolio of multiple coins, each must be valued separately. The executor should take a screenshot or PDF of the exchange’s price feed for that date and retain it with the estate papers.

Case example: Mrs X, a 68‑year‑old widow, held 12.5 Bitcoin at her death in March 2024. The Coinbase closing price on the date of death was £48,230 per Bitcoin, giving a total estate value of £602,875 from crypto alone. Her nil‑rate band of £325,000 was fully used, and the excess £277,875 attracted IHT at 40% — a liability of £111,150. The executor used the Coinbase daily price report as the valuation source, and HMRC accepted it without challenge.

For tokens traded only on decentralised exchanges (DEXs) with no central price feed, the executor should use the volume‑weighted average price from a reputable aggregator such as CoinGecko or CoinMarketCap for the death date. HMRC’s Cryptoassets Manual (CRYPTO20050) confirms that “reasonable endeavours” to obtain a market value will be accepted, provided the methodology is clearly stated in the IHT400 supplementary pages.

Reporting Online Accounts and Digital Business Interests

Beyond cryptocurrency, many estates now contain online accounts that hold monetary value but are not immediately obvious. Common examples include:

E‑commerce storefronts (Etsy, Amazon, eBay) with unpaid balances, inventory, or intellectual property.
Freelance platforms (Upwork, Fiverr, OnlyFans) where earnings sit in a digital wallet.
Domain names with resale value — a premium domain can be worth tens of thousands of pounds.
Digital copyrights on YouTube channels, podcasts, or written content that generate ongoing royalty income.

Each of these must be valued and reported. For a domain name, the executor can obtain a valuation from a specialist broker or use comparable sales data from NameBio or Sedo. For a YouTube channel, the value is typically a multiple of the trailing 12 months’ ad revenue, less any platform fees. HMRC’s Business Asset Valuation (BAV) team can provide a formal opinion if the executor is uncertain, but the process can take 6–12 months.

Case example: Mr Y, a 55‑year‑old digital creator, died suddenly in 2023. His estate included a YouTube channel with 450,000 subscribers and annual ad revenue of £38,000, plus an Etsy store with £12,000 in pending payments and £8,000 in raw material inventory. The executor valued the YouTube channel at 3× annual revenue (£114,000) using a standard industry multiple, and the Etsy store at its net realisable value (£20,000). HMRC accepted both valuations after the executor provided platform‑generated revenue statements for the previous 12 months.

The Executor’s Duty to Identify and Access Digital Assets

One of the most common problems in digital‑asset probate is access. If the deceased did not leave a password manager, a list of accounts, or a digital legacy instruction, the executor may be locked out of valuable holdings. The UK’s Data Protection Act 2018 and the Privacy and Electronic Communications Regulations (PECR) do not give executors an automatic right to access a deceased person’s online accounts.

However, most major platforms now have deceased‑user policies:

Google’s Inactive Account Manager allows users to nominate a trusted contact who can access data after a period of inactivity.
Apple’s Digital Legacy programme lets users add up to five Legacy Contacts who can request access after death.
Facebook (Meta) will memorialise an account or provide a “legacy contact” with limited access.

For cryptocurrency held in a self‑custody wallet (hardware wallet or non‑custodial software), there is no central authority to turn to. If the private keys or seed phrase are lost, the crypto is permanently inaccessible and its value is zero for IHT purposes. HMRC accepts this, but the executor must be able to demonstrate that reasonable steps were taken to locate the keys — for example, searching the deceased’s physical safe, digital files, and password manager.

Where the executor cannot access an account, they should file the IHT400 with a note that the asset is “unrealisable pending access” and provide an estimated value. Once access is granted, the executor must update HMRC within six months. For cross‑border estates where the deceased held crypto on a foreign exchange, some international families use platforms like Airwallex global account to consolidate and repatriate funds efficiently, though tax advice from a dual‑qualified solicitor is strongly recommended.

HMRC’s Enforcement and Penalty Framework for Digital Assets

HMRC has significantly increased its focus on digital assets in the last three years. In 2023, it issued “nudge letters” to over 10,000 UK taxpayers suspected of holding unreported crypto, and it now requires all crypto exchanges registered with the Financial Conduct Authority (FCA) to report transaction data to HMRC under the OECD’s Crypto‑Asset Reporting Framework (CARF), effective from 2026.

For IHT specifically, the penalties for non‑disclosure of digital assets are severe. If HMRC discovers a digital asset that was not reported, it can charge:

Up to 30% of the tax due for a careless (non‑deliberate) failure to report.
Up to 100% for a deliberate failure, and up to 200% if the deliberate failure is concealed (e.g. transferring crypto to a non‑FCA‑registered exchange before death).

The IHT400 includes a specific supplementary page (IHT400‑DIG) for digital assets, introduced in April 2024. Executors must list each digital asset, its value at death, the valuation source, and the location (exchange address or wallet identifier). HMRC may ask for additional evidence, such as exchange statements or blockchain transaction records.

For estates where the total digital asset value is below £10,000, executors can aggregate them as “other personal property” on the main IHT400 form, but they must still keep a detailed breakdown in the estate accounts. For estates above this threshold, individual listing is mandatory.

Practical Steps for Executors and Estate Planners

Given the complexity of digital‑asset IHT, proactive estate planning is essential. The following steps can save time, money, and stress:

Maintain a digital asset inventory. The deceased should keep a regularly updated list of all crypto wallets, exchange accounts, and online platforms with monetary value, along with access instructions. This list should be stored with the will or in a secure digital vault.
Use a password manager. A service like 1Password or Bitwarden allows a designated “emergency contact” to request access after a period of inactivity, avoiding the need for court orders.
Include a digital legacy clause in the will. A specific clause authorising the executor to access, transfer, or sell digital assets — and indemnifying the executor for any platform terms‑of‑service violations — is now standard practice in solicitor‑drafted wills.
Obtain a professional valuation for large holdings. For crypto portfolios above £250,000 or complex digital businesses, a chartered valuation surveyor or a specialist crypto accountant can provide a report that HMRC will treat as authoritative.
Consider life insurance to cover the IHT liability. If the digital assets are highly volatile, a decreasing‑term life insurance policy written in trust can ensure the estate has cash to pay the IHT bill without being forced to sell crypto at a low point.

The Office of Tax Simplification’s 2022 report on IHT administration recommended that HMRC issue clearer guidance on digital asset valuation, and in response, HMRC published its “Cryptoassets for Inheritance Tax” factsheet in September 2023. Executors should download this factsheet and keep it with the estate papers.

FAQ

Q1: Do I need to report a cryptocurrency holding of less than £1,000 on the IHT400?

Yes. There is no de minimis threshold for digital assets. Any cryptocurrency or digital token held at the date of death must be reported, even if the value is below £1,000. However, if the total value of all digital assets is under £10,000, you may aggregate them under “other personal property” on the main IHT400 form, rather than completing the separate IHT400‑DIG page. HMRC expects executors to keep a detailed schedule of the individual assets for their own records.

Q2: How does HMRC value an NFT that has no recent sales?

For non‑fungible tokens (NFTs) with low trading volume, HMRC accepts a valuation based on the most recent arm’s‑length sale within the 12 months before death, adjusted for any material change in market conditions. If no sale exists, the executor should obtain a written valuation from a recognised digital art appraiser or auction house (e.g. Christie’s Digital or Sotheby’s Metaverse). HMRC’s IHTM27155 allows the use of “any reasonable method” and will not challenge a valuation that is supported by a professional opinion.

Q3: What happens if the executor cannot access the deceased’s cryptocurrency wallet?

If the private keys or seed phrase are lost and there is no third‑party exchange that can reset access, the cryptocurrency is treated as an asset of zero value for IHT purposes. HMRC requires the executor to provide a signed statement explaining the steps taken to locate the keys — for example, searching the deceased’s home, digital files, and contacting known associates. If the keys are later found, the executor must notify HMRC within six months and file an amended IHT400.
