In a world of increasingly complex tax legislation and scrutiny from tax authorities, it is vital that successful individuals and businesses obtain the necessary support to ensure they are not only meeting their obligations but doing so in a tax efficient manner.

At Grant Thornton, we provide a personal, proactive and partner-led approach to both advisory and compliance work. Our team of experienced tax advisors provide advice to a diverse range of clients throughout every stage of the business lifecycle.

Grant Thornton Isle of Man is part of Grant Thornton Ireland all-island tax practice comprising over 200 tax professionals who can provide innovative, robust and commercially aligned tax advice across both UK and ROI tax jurisdictions. 

Our team can advise on the expatriate and international tax issues, support international expansion through our global mobility services and provide access to our global network in over 130 countries to ensure compliance with international tax regimes.

Our Tax

Company Tax

Our tax team is made up of highly experienced professionals who work with our clients to ensure they are compliant with all aspects of their corporation tax obligations by gaining a deep understanding of the businesses.

Global mobility services

Grant Thornton offer a different approach to managing global mobility. We have brought together specialists from our tax, global payroll, people and change and financial accounting teams

Indirect Tax

Our Indirect Tax team helps businesses manage their IOM, UK and global indirect tax risks which, as transactional taxes, can quickly become large liabilities.

International Tax

We work closely with our colleagues globally to provide a seamless multi-jurisdiction service offering which ensures clients have an appropriate tax structure that mirrors what they are doing operationally – a key consideration in a world where it is no longer possible to separate a company’s tax and operational presences.

Private Client

Our team of experienced advisors can assist and navigate you through the tax issues arising when establishing a business, moving to the Island, leaving the island, passing on wealth alongside residence and domicile issues. We can help minimise the impact that taxes, such as income tax, capital gains tax and inheritance tax, may have upon your personal wealth.
