CST firms are passionate about supporting Global Executives. We have empathy to their needs.


Global Executives are senior executives working for large multinational corporations who have been posted internationally. They require high-quality tax advice and specialised knowledge that CST Firms can provide. They expect their income tax advisory needs will be serviced with the same level of expertise and dedication that their employers expect from them.

As a CST International member firm, you will have an outstanding opportunity to be a recognised leader in advising Global Executives in your country and helping them on their career journey, often establishing long lasting professional relationships as a trusted advisor to top international talent.

We understand the unique challenges facing Global Executives. We understand and embrace Expatland, it is where we live.

Looking back now it would have been fantastic to have had a road map..."
