Total employer & employee solutions

You have better things to do than your taxes.
Let us take care of what we do best.

Expat Tax Services

We provide high quality expat tax services. And when we say services, we mean service in the first place. In an industry where poor service is an often heard complaint, we make a positive stand to unburden you and your organisation through true attention and care.

Free Expat Payroll Scan

We have learned that many organisations are uncomfortable with the compliance status of their expat payroll. With years of experience in the field, we have developed an approach to quickly diagnose the status and provide insight in your main areas of risk and opportunities for improvement.


Nice to meet you.

We are Triple T. We help enterprises with the tax and legal aspects of their global mobility and compensation & benefit programs.

Young enough to be creative, unconventional and unreasonable, yet old enough to bring the expertise and experience (and maybe even a few grey hairs) to the table. A mix that ensures our focus is on solutions for your challenges, instead of problems for our solutions.

We combine geeky technical expertise with practical experience of process and policy. This results in solutions that work as well in design as they do in practice. We call this Total Solutions. Because we believe advisory is nothing without delivery.
