International tax

What is international tax? 

International tax is the application of taxes and tax law across national borders, as it relates to individuals, businesses and government agencies engaging in commerce, employment or other financial transactions which involve more than one country. As tax laws and policies vary significantly between countries and territories, cross-border taxation requires expert knowledge to interpret, which ADIT – our international tax qualification – can help you to develop. 

Do you have the skills to succeed? 

International tax professionals are highly analytical and innovative, with a keen eye for detail. To succeed in this environment, you will be expected to act with the drive and integrity needed to help your clients navigate complex technical and regulatory landscapes. You will need to stay on top of the current trends and changes in legislation, and guide businesses to operate responsibly, sustainably and ethically. 

With ADIT, you will build these skills and grow as a professional, ready to take the next step in your career.

Coming soon: our Pillar Two Award

In the post-BEPS environment, Pillar Two promises to fundamentally reshape how multinational groups are taxed across jurisdictions, with profound implications for states, taxpayers and advisers alike.

The CIOT’s cutting edge Pillar Two Award, a standalone spin-off of the ADIT qualification, will guide tax professionals in countries around the world on Pillar Two’s key concepts and their practical implementation.
