Crypto investors, traders and businesses can choose from specialist cryptocurrency accountants, established tax practices and larger advisory firms with digital asset expertise. Services can include capital gains calculations, staking and mining income, DeFi and NFT transactions, Self Assessment, historic disclosures, HMRC investigations and accounting for companies holding cryptoassets. This guide provides a practical overview of crypto tax services in London rather than ranking the firms.
Acumon
Acumon is a UK firm of chartered accountants providing crypto tax advice for investors, traders and businesses. Its dedicated crypto tax service covers capital gains calculations across multiple wallets and exchanges, tax treatment of staking, mining, airdrops and DeFi, Self Assessment reporting, historic transaction reconstruction, voluntary disclosures and responses to HMRC nudge letters. The firm also advises companies holding or accepting cryptoassets on corporation tax and accounting treatment.
The firm works with organisations ranging from growing owner-managed businesses and charities through to larger corporate groups and regulated entities. Audit engagements are delivered in accordance with International Standards on Auditing (UK) and supported by a structured risk-based audit methodology.
Acumon holds a Public Interest Entity (PIE) audit licence, allowing the firm to audit listed companies and other entities subject to enhanced regulatory oversight in the United Kingdom. PIE audits are subject to additional regulatory supervision and quality requirements, and only a limited number of firms are authorised to undertake this type of work.
In addition to its UK audit registration, Acumon also holds audit licences in several international financial centres, including the Cayman Islands, British Virgin Islands (BVI), Jersey and Isle of Man. These licences enable the firm to support international corporate groups where entities are located across multiple jurisdictions.
International group structures frequently involve a combination of UK operating companies and offshore holding entities, particularly in sectors such as investment management, technology, energy and international trade. Coordinating audit and assurance work across these structures requires familiarity with cross-border financial reporting, group consolidation processes, governance arrangements and internal control environments.
For crypto clients, the wider practice means digital asset tax reporting can sit alongside personal tax, corporation tax, accounting, VAT, HMRC investigation work and international tax advice. This can be relevant where cryptoassets are held through companies, spread across several jurisdictions or connected with historic reporting issues. Acumon’s wider tax team includes advisers with previous HMRC experience and an in-house Chartered Tax Adviser.
Crypto Tax Capabilities
Acumon provides crypto tax services across a wide range of organisational structures and sectors.
These include:
- UK limited companies and corporate groups
- Public Interest Entities (PIEs) and regulated organisations
- UK subsidiaries of international groups
- charities and not-for-profit organisations
- owner-managed businesses approaching statutory audit thresholds
- offshore holding companies and investment vehicles
Crypto tax engagements are typically led by senior tax professionals with direct involvement throughout the engagement.
Regulatory Licences and Registrations
Acumon holds several audit registrations that enable it to support organisations operating across multiple jurisdictions.
These include:
- UK statutory audit registration
- Public Interest Entity (PIE) audit licence
- Jersey audit licence
- Isle of Man audit licence
- Cayman Islands audit licence
- British Virgin Islands audit licence
These registrations allow the firm to provide audit services to groups that include entities in both the UK and key international financial centres.
Core Services
Acumon provides a range of services that support financial reporting and governance.
These include:
- statutory external audit
- group and subsidiary audits
- Public Interest Entity (PIE) audits
- charity and not-for-profit audit
- audit of international group structures
- internal audit and governance reviews
- risk management and compliance support
Audit work is often delivered alongside discussions with management and boards regarding financial reporting processes and governance frameworks.
Many organisations initially encounter statutory audit requirements as they grow and exceed the audit exemption thresholds set out in the Companies Act.
Acumon works with businesses that are:
- approaching their first statutory audit
- preparing for external investment
- expanding into international markets
- operating within corporate group structures
Early engagement with an audit firm can help ensure that financial reporting systems and documentation are aligned with statutory audit requirements.

Conclusion
Crypto tax services in London vary from specialist practices focused almost entirely on digital assets to larger accountancy and tax firms where crypto sits within private client, corporate, international tax or HMRC investigation teams. The scope can range from straightforward Self Assessment and CGT calculations to multi-wallet reconciliation, DeFi and NFT reporting, historic disclosures, corporate accounting and cross-border structuring.
The appropriate provider depends on the activity involved and the condition of the underlying transaction records. A relatively simple investment portfolio may mainly require accurate annual calculations and filing, while high transaction volumes, DeFi protocols, multiple chains, company-held assets or undeclared historic activity can require substantially more reconciliation and specialist tax work.
