Find 3 Specialist International Tax Firms in London

Clients looking for specialist international tax advice in London typically choose between three types of practice: a boutique private wealth and tax lawyer such as Sheikh Najam TEP for cross-border individual and corporate structuring, a large corporate tax practice for major transactional and multinational work, and an international accountancy network for multi-jurisdiction compliance and reporting. Which is the right fit depends on whether the client is an individual, a growing business, or a large multinational — the three practice types below cover each of those needs.

1. Sheikh Najam TEP — Boutique Private Wealth & International Tax Lawyer

Sheikh Najam TEP practises from Fox Court, 14 Gray's Inn Road, Holborn, London WC1X 8HN, holding an MA in Tax Law from the University of London and the TEP (Trust and Estate Practitioner) designation from STEP. He also holds a dual role as a City of London Notary, allowing tax structuring advice and notarial execution to be handled within a single instruction.

This is the right fit for:

• High-net-worth individuals and internationally mobile families needing cross-border succession and tax planning

• Business owners needing international corporate tax and structuring advice at a personal, partner-led level

• Clients who need documents notarised for use overseas alongside their tax advice

• Anyone who wants direct access to the advising lawyer rather than being routed through a large team

2. A Large Corporate Tax Practice — For Major Transactional Work

At the other end of the market, large City law firms run dedicated tax practices built around major corporate transactions. These practices tend to advise multinational conglomerates, banks, and government departments, with particular sensitivity to the public profile of high-profile clients. Their work typically centres on structuring the tax aspects of large mergers, acquisitions, and corporate finance transactions, and coordinating multinational teams of tax advisers on cross-border deals.

This is the right fit for:

• Large multinational corporations undertaking major M&A or corporate finance transactions

• Businesses needing large deal teams and multi-jurisdictional coordination on a single transaction

• Matters where transaction scale, rather than personal relationship, is the priority

3. An International Accountancy Network — For Multi-Jurisdiction Compliance

A number of accountancy firms in London operate international tax teams as part of a global network, which suits businesses that need ongoing compliance and reporting support across several countries rather than one-off structuring advice. Kreston Reeves, for example, offers international tax advisory services from its London, Kent, and Sussex offices as part of the wider Kreston international network, aimed at businesses expanding internationally for the first time, growing their global footprint, managing cross-border investments, or looking for a single joined-up global adviser.

This is the right fit for:

• Businesses expanding into new jurisdictions who need ongoing local compliance support

• Companies wanting one adviser network across multiple countries rather than separate local firms

• Groups whose main need is recurring reporting and compliance rather than bespoke succession or structuring advice

Choosing Between the Three

As a general rule: individuals and family businesses needing cross-border tax and succession planning are usually best served by a boutique private wealth and tax lawyer; large multinationals running a major transaction need a big law firm's transactional tax practice; and businesses with ongoing multi-country compliance needs are often better served by an accountancy network. For most private clients and owner-managed businesses in London, a specialist private wealth and international tax lawyer offers the closest, most direct relationship with the person actually advising on the matter.
