Worried about the tax, reporting and inheritance risks of holding Bitcoin in the UK? Many owners face a complex choice: hold personally, place assets into a trust, or operate through a special purpose vehicle (SPV). The right structure affects Capital Gains Tax (CGT), Income Tax, Corporation Tax, reporting burdens and succession planning.
Clear, practical options exist. The sections below explain when a trust makes sense for Bitcoin holdings, how to set up an SPV in England, how trusts change CGT outcomes, a direct comparison of SPV versus personal ownership for UK tax purposes, HMRC reporting and anti‑avoidance risks, and how trusts interact with Inheritance Tax (IHT) and crypto inheritance. Technical references and official links are cited throughout.
Key takeaways: what to know in 1 minute
- Choose a trust where control and succession matter or where assets must be safeguarded for beneficiaries; trusts create separate tax entities with distinct reporting and annual charges.
- SPVs suit active investment businesses or pooled investment purposes; they attract Corporation Tax but allow retained profits and clearer corporate governance.
- Transfers into a trust or SPV can trigger a disposal for CGT at market value unless specific relief applies; trustees and companies have different tax rates and allowances than individuals.
- HMRC attention on crypto is high: make full disclosures on Self Assessment, use HMRC guidance and expect general anti‑avoidance rules to apply to contrived arrangements.
- Succession planning needs private key arrangements (wills, trustee powers, multisig) alongside tax planning to ensure executors or trustees can access assets.
When to use a trust for Bitcoin holdings
A trust is primarily an ownership and governance tool. For Bitcoin, a trust is suitable when one or more of the following apply:
- preservation of assets for minors or vulnerable beneficiaries;
- separation of legal ownership from beneficial entitlement (for example, when a custodian holds keys);
- desire to set binding distribution rules and protect assets from a beneficiary’s creditors;
- estate planning to control timing of benefit and potential IHT mitigation.
Trusts are not usually tax‑motivated silver bullets. HMRC treats trusts as separate taxpayers with different allowances and tax rates; a trustee faces reporting duties and often a smaller annual CGT exemption than individuals. For straightforward, short‑term speculative holdings the administrative cost often outweighs benefits.
Types of trust commonly used for crypto
- Bare trusts: beneficiary has absolute entitlement; for CGT and IHT the asset is treated as belonging to the beneficiary. Useful for simple intergenerational transfers.
- Interest in possession trusts: a beneficiary has the right to income; capital remains for other beneficiaries. Income and gains can be taxed on the life tenant.
- Discretionary trusts: trustees decide distributions. Greater flexibility but greater tax and reporting complexity; trustees pay special rates and the trust has its own tax year and allowances.
Practical triggers for using a trust
- a need to restrict access to keys pending a beneficiary's maturity;
- protecting holdings from a beneficiary’s commercial risk or marriage breakdown;
- ensuring professional trustee oversight when family members lack technical knowledge;
- combining crypto with other family assets under a formal governance structure.
How trusts affect Capital Gains Tax on crypto
Trusts and trustees are taxed differently from individuals. Key technical points for Bitcoin:
-
Disposal on transfer into a trust: transferring crypto into a trust can constitute a disposal at market value for CGT. The transferor may trigger a charge on any gain accrued to that point unless special relief or a no‑gain/no‑loss rule applies (such as when transferring to a bare trust for a beneficiary entitled absolutely).
-
Trust annual exempt amount: trusts generally have a smaller CGT annual exempt amount than individuals (check current HMRC figures). Trustees must track gains in the trust tax year and may be liable to pay CGT at trustees’ rates.
-
Rates: trustees normally pay CGT at rates set for trusts; for most non‑residential assets the effective rate is often aligned with the higher rates charged on trusts. For precise rates and thresholds consult HMRC: Trusts and taxes.
-
Base cost and pooling: Bitcoin is treated as a capital asset. When assets move into a trust the trustees' base cost is usually the market value at the date of transfer (subject to the disposal rules above). Proper records must evidence acquisition dates, amounts and any chain of transactions (including transfers between wallets), since HMRC will expect accurate basis calculations.
-
Distributions and gain crystallisation: when trustees transfer crypto to beneficiaries, further disposals or chargeable events may arise. Trustees must consider whether distributions are treated as chargeable transfers and whether hold‑over relief or other reliefs apply.
Practical example: if an individual acquired 1 BTC at £5,000 and transfers it into a discretionary trust when market price is £50,000, the transferor may be treated as having disposed of the asset and liable for CGT on the £45,000 gain (subject to allowances). Trustees then hold the asset with a base cost of £50,000 for future disposals.
Setting up an SPV for crypto investments in England
An SPV is typically a limited company formed to hold and operate crypto investments. SPVs are common where investors want a corporate wrapper for pooling funds, separating operational risk, or operating a trading strategy.
- usual form: private company limited by shares (Ltd).
- purpose: hold crypto as an investment, execute trading strategies, or offer shares to investors.
- governance: articles of association, shareholders' agreement, director duties under the Companies Act 2006.
Step-by-step: how to set up an SPV (high level)
- Choose company name and structure; decide on share classes and shareholder rights.
- Draft articles of association and a shareholders' agreement that cover investor protections and exit mechanisms.
- Appoint directors and, where appropriate, a corporate secretary or professional nominee directors.
- Register at Companies House and obtain a company registration number.
- Open a corporate bank account and arrange crypto custody (self‑custody multisig or regulated custodian).
- Put in place AML/KYC processes and register for relevant tax regimes (Corporation Tax with HMRC) and, where necessary, Anti‑Money Laundering supervision.
Official references: register the company via Companies House and review HMRC guidance at HMRC corporation tax.
Costs and timeline
- Typical costs: Companies House fee (small), legal fees (from a few hundred to several thousand pounds for detailed shareholder documents), professional trustee or director fees, custody or exchange fees, and annual compliance costs (accounts, tax returns, audit where applicable).
- Timeline: rudimentary company formation can take 1–3 working days; full operational readiness (bank account, custody and investor documentation) commonly takes 4–8 weeks.
Operational considerations
- Custody: SPV must decide between institutional custodians, third‑party custody providers or a robust multisig arrangement under a clear trustee/director order of operations.
- AML/KYC: investors in the SPV and counterparties must be screened; Money Laundering Regulations apply to certain crypto business activities — see UK guidance and FCA supervision where required.
- Accounting: valuations of crypto assets for company accounts must be consistent and defensible; record timestamps, exchange data and signed custody confirmations.

SPV versus personal ownership: UK tax implications
Choose between personal ownership and an SPV depending on objectives: taxation, access to capital, governance, investor participation, and exit strategy.
| Feature |
Personal ownership |
SPV (private company) |
| Tax on gains |
Individual CGT rates; annual exempt allowance applies. |
Corporation Tax on trading/investment gains; distributions taxed when paid as dividends. |
| Administrative overhead |
Low — Self Assessment reporting and record-keeping required. |
Higher — company accounts, corporation tax returns, payroll, possibly audit. |
| Access to external capital |
Limited; personal borrowing against assets possible. |
Easier to accept investors, issue shares and formalise profit-sharing. |
| Succession |
Assets pass via will; private key arrangements critical. |
Shares can be transferred or controlled by shareholders’ agreement; directors manage operations. |
Example comparison (simplified)
Assume a sale generates a £200,000 gain. Under personal ownership the individual pays CGT on the net gain after annual allowance at applicable rates. Under an SPV, the company pays Corporation Tax on the gain, then any distribution to shareholders as dividends will carry further tax at the shareholder level — resulting in potential double taxation but with more control over timing, retention and reinvestment. The optimal choice depends on the individual's marginal tax rate, intended use of proceeds and desire to leave capital within a corporate wrapper.
Reporting, compliance and HMRC anti‑avoidance for crypto
HMRC views crypto seriously. Reporting and compliance duties include:
- Self Assessment: individuals must report chargeable disposals and gains in their Self Assessment tax return where applicable. HMRC guidance is available at Tax on cryptoassets.
- Company reporting: SPVs must include crypto valuations and realised gains in statutory accounts and corporation tax returns.
- Anti‑money laundering: where the business carries on regulated crypto activities (exchange, custody, advisory), registration with the FCA as a cryptoasset business may be required.
- International reporting: cross‑border arrangements may trigger CRS/FATCA reporting and information exchange; trustees and companies with non‑UK beneficiaries or shareholders must consider these obligations.
- Anti‑avoidance: HMRC can challenge arrangements constructed solely to avoid tax. The General Anti‑Abuse Rule (GAAR) and specific transfer rules apply; see HMRC GAAR guidance.
Practical compliance checklist:
- keep timestamped transaction records with source and destination addresses;
- retain exchange records and wallet export data to prove provenance and costs;
- produce audited valuations if balances are material in company accounts;
- obtain professional tax rulings or documented opinions for novel structures.
Succession planning: trusts, IHT and crypto inheritance
Crypto raises two distinct succession challenges: legal tax treatment on death (IHT and CGT) and practical access to keys.
Inheritance Tax and trusts
- IHT treatment: transfers into some trusts are treated as potentially exempt transfers, chargeable lifetime transfers or relevant property depending on the trust type. Discretionary trusts attract periodic ten‑year charges and exit charges which must be modelled against potential IHT savings.
- Wills and digital estate: wills should include clear instructions on encryption keys and access methods. A separate, secure key escrow mechanism is often advisable.
- Trust language: trust deeds must include powers for trustees to access, transfer and dispose of crypto assets; ambiguous deed terms can prevent trustees from acting and expose beneficiaries to loss.
Practical steps for inheritance
- record precise key access plans in a secure system and link them legally to executors or trustees;
- use multisig with co‑signers named in trust instruments to avoid single‑point failures;
- consider professional custody with defined succession procedures; custodians often maintain legacy access mechanisms for estates.
Advantages, risks and common mistakes
✅ Benefits and when to apply
- asset protection and governance for family wealth;
- clearer investor structures for pooled strategies via an SPV;
- ability to retain profits within a company for reinvestment;
- formal succession pathways using trust mechanics and trustee duties.
⚠️ Risks and errors to avoid
- failing to account for CGT on transfers into structures;
- leaving private key and access arrangements informal or undocumented;
- underestimating ongoing compliance costs (accounts, tax returns, AML);
- using structures primarily for tax avoidance — HMRC may challenge arrangements.
Common operational mistakes
- inadequate custody controls (single private key without multisig);
- poorly drafted trust deeds that lack express crypto powers;
- inconsistent valuation methodology across reporting periods.
Frequently asked questions
Can a trust reduce CGT on Bitcoin sales?
A trust does not inherently reduce CGT; transfers into trusts can trigger disposals and trusts have different (often less generous) allowances. Use trusts for control and succession rather than solely for CGT reduction.
How does an SPV change tax on crypto profits?
An SPV pays Corporation Tax on trading or investment gains, allowing retained profits to be reinvested but exposing distributions to shareholder tax on dividends when extracted.
Will HMRC accept a multisig held by trustees?
Yes, provided trustees can evidence control and lawful authority. Documentation, trustee resolutions and custody proof are essential to satisfy HMRC and auditors.
Are transfers between personal wallets and a trust taxable?
Often treated as a disposal at market value unless specific rules intervene (e.g. bare trust to beneficiary). Accurate records and valuations at transfer date are critical.
Is an SPV suitable for one individual's Bitcoin holding?
Typically not, unless there is a trading/business rationale, external investors or a need for corporate governance. Admin and tax costs often outweigh benefits for sole personal holdings.
How should private keys be handled in succession planning?
Use documented multisig arrangements, secure escrow with legal instructions, or regulated custodians with estate procedures. Avoid storing keys only in wills or unsecured notes.
Do trustees have to register trusts with HMRC for crypto?
Trusts must be registered where required, and trustees must report gains. Where a trust holds UK taxable assets or has tax liabilities, HMRC registration and returns will be necessary.
What anti‑avoidance risks exist for trusts and SPVs holding crypto?
Arrangements that artificially divert gains or exploit mismatches to avoid tax can be challenged under GAAR, transfer rules or international exchange of information regimes.
Can an SPV claim reliefs on losses from crypto trading?
Companies can offset certain trading losses against profits subject to corporation tax rules. Classification as trading or investment activity is determinative and must be supported by commercial evidence.
Your next step:
- Seek a tailored review: instruct a UK tax adviser to model CGT, Corporation Tax and IHT outcomes for the exact holdings and objectives.
- Secure keys and governance: implement a multisig or regulated custody solution and draft trustee/shareholder documents specifying access and succession.
- Prepare records: export timestamped transaction histories, valuations and custodial evidence to support any transfer or disposal filings.
