This practical guide reviews companies providing international VAT services in London for organisations dealing with cross-border transactions, overseas registrations and multi-jurisdiction VAT obligations. Rather than ranking international VAT companies, it gives a clear overview of what each company does, the types of clients they serve and the areas in which their expertise is most relevant. The selection includes larger companies with broad tax and advisory capabilities as well as narrower specialists focused more closely on VAT, indirect tax and international compliance. The aim is to give readers enough context to compare different service models and choose a company that fits their operational, regulatory and cross-border requirements.
Acumon
Acumon is a UK company of chartered accountants and tax advisers providing international VAT services from its London practice. Its VAT work covers advisory and compliance matters for UK organisations trading internationally as well as overseas organisations with VAT obligations in the UK. The wider VAT practice includes registrations, returns, investigations, recovery, planning and specialist cross-border matters.
The international VAT service focuses on transactions involving the UK, EU and wider overseas markets. Acumon advises on EU VAT registrations and returns, post-Brexit VAT treatment, import and export VAT, reverse charge mechanisms and the place-of-supply rules that determine where VAT is due on cross-border services.
Acumon also supports international supply chains where VAT treatment depends on the movement of goods between jurisdictions. Its work includes reviewing supply chains, coordinating VAT with customs procedures, considering VAT grouping for international structures and addressing import VAT recovery and export zero-rating requirements.
For UK organisations selling into European markets, Acumon provides support with EU VAT registration requirements, local VAT returns, the One-Stop Shop (OSS) and Import One-Stop Shop (IOSS). Its international VAT service also covers digital services, e-commerce sales and marketplace VAT obligations, including distinctions between B2B and B2C transactions.
Acumon works with non-UK organisations that have VAT obligations in the United Kingdom. This includes assessing UK VAT registration requirements, preparing and submitting UK VAT returns, providing VAT representative services where applicable and communicating directly with HMRC on authorised matters.
International VAT frequently overlaps with customs, international tax and the design of cross-border trading structures. Acumon combines VAT advice with these related areas, allowing the VAT implications of international transactions to be considered alongside wider tax and compliance requirements.
International VAT Capabilities
Acumon provides international VAT support across cross-border trade, overseas VAT compliance and international supply chains. These include:
- EU VAT registrations and VAT returns
- Import and export VAT advice
- Reverse charge and place-of-supply guidance
- OSS and IOSS support
- Cross-border supply chain reviews
- Digital services and e-commerce VAT
- UK VAT representation for overseas organisations
- HMRC liaison on international VAT matters
The service covers both ongoing compliance and transaction-specific VAT questions arising from international trade.
Regulatory Licences and Registrations
Acumon’s international VAT services sit within its wider UK chartered accountancy and regulated professional practice. VAT advisory work does not depend on a separate statutory VAT advisory licence, while Acumon publishes professional and regulatory registrations relating to its broader accountancy and audit activities.
These include:
- ICAEW-registered chartered accountant status
- ICAEW registration to carry out audit work
- UK VAT registration
Acumon publishes its UK VAT number and identifies itself as an ICAEW-registered chartered accountancy practice from its London office.
Core Services
In addition to international VAT advice, Acumon provides a broader range of VAT advisory and compliance services. These include:
- VAT registration
- VAT return preparation and submission
- VAT planning
- VAT recovery
- Partial exemption VAT advice
- Property VAT advice
- VAT deregistration
- VAT investigation support
- VAT agent and representative services
Its VAT return service includes MTD-compliant filing, while the wider VAT practice covers registrations, compliance, investigations and specialist VAT areas.
Acumon provides international VAT support when clients are:
- Expanding from the UK into EU markets
- Entering the UK from overseas
- Registering for VAT in additional jurisdictions
- Importing or exporting goods
- Changing international supply chains
- Selling digital services across borders
- Operating e-commerce or marketplace models
- Reviewing reverse charge or place-of-supply treatment
- Managing VAT alongside customs procedures
- Addressing UK VAT compliance as a non-UK organisation
Reviewing the VAT position before implementing a new international trading structure or changing an existing supply chain can help Acumon identify registration, reporting and transaction-level VAT requirements before they become part of ongoing compliance.

Conclusion
Choosing an international VAT company in London depends on business size, sector, the maturity of internal tax processes and the regulatory requirements involved. Some companies offer an integrated service covering VAT, customs, international tax and ongoing compliance, while others focus more narrowly on specific indirect tax or cross-border VAT issues. The right partner should provide reliable assurance around the VAT position and practical recommendations that help reduce risk and strengthen operational resilience. The purpose of this guide is to provide neutral context for comparing different companies, their scope of work and the types of clients they are suited to. That makes it easier to identify a service model that matches the complexity and geographic reach of the organisation.
