Behind the Stats: Building a High-Performance International Tax Team

Written by Aidan James | Apr 10, 2026 2:34:54 PM

When we talk about international tax, the conversation usually gravitates toward technical complexity - Double Tax Agreements, residency triggers, or the latest HMRC scrutiny. But at TAP, we’ve always believed that the quality of that advice is a direct result of the team behind it.

Internal benchmarks like our 89% staff retention rate and a gender pay gap of less than 1% might look like "back-office" metrics. In practice, they are the reason we can handle the "heavy lifting" of cross-border tax without the friction you often find in larger, higher-turnover firms.

 

Why retention matters to our clients

International tax isn’t just a one-off project; it’s a story that unfolds over years. Whether you are a family moving across borders or a business expanding into the UK, you need more than just a technical answer, you need a team that remembers the "why" behind your decisions. In an industry where people often jump from firm to firm, we’ve taken a different path.

We focus on keeping our specialists for the long haul because that continuity is what protects our clients. It means the person who helped design your tax structure three years ago is still right here to help you manage it today. This creates a level of insight you simply can’t get from a rotating door of new faces. By keeping our team stable, we make sure that the deep, personal knowledge of your affairs stays right where it belongs: with the people looking after you.

 

Equity as a foundation for excellence

We also don't view gender pay or a supportive culture as optional extras. To maintain a team of regulated advisers across the CIOT, ICAEW, and the IRS, you have to provide an environment where people actually want to work.

That internal stability is what allowed us to manage a 101% increase in enquiries last year while still delivering over 260 complex advisory projects. Because our Corporate, Private Client, and US tax specialists genuinely collaborate - without the silos of "corporate red tape" - we can move faster and more accurately for our clients.

 

A quiet validation

This link between a healthy culture and high-level output is likely why we’ve been named a finalist for the 2026 Tolley’s Taxation Awards for Best International Tax Team. Being a finalist is a great milestone for the team, and we’re looking forward to the event on 14 May. But for us, the nomination is really a validation of our "one team" philosophy. It proves that you can build a leading international tax practice by putting people, both our clients and our staff - first.

 

Looking toward 2026/27

With global transparency rules and domestic tax reforms continuing to shift, the next couple of years won't be quiet. We’re staying focused on the formula that got us here: blending technical precision with a team that is stable, valued, and ready for whatever comes next.
