Global mobility in financial and professional services: a governance challenge hiding in plain sight

Financial and professional services remain one of the UK’s largest and most economically significant industries, employing almost 2.5 million people across banking, insurance, asset management, legal services, accountancy and consultancy. The sector has always depended on the movement of people across borders. Whether it is a portfolio manager overseeing investments across multiple markets, a bank supporting multinational clients, an insurer expanding into new territories, a private equity house deploying investment professionals internationally, or a law firm transferring partners and specialists between offices, international mobility remains central to growth, client service and operational effectiveness.

Traditional expatriate assignments have been joined by regional leadership structures, frequent business travellers, internationally mobile executives, overseas directors, cross-border project teams and increasingly flexible remote and hybrid working arrangements. These models support commercial objectives, but they also create tax, regulatory and governance considerations that many organisations struggle to monitor consistently.

In a sector built on controls, accountability and risk management, the challenge is no longer understanding the rules. The challenge is maintaining visibility over a workforce that is increasingly operating across borders.

Why financial and professional services firms should be paying attention

Financial and professional services organisations operate in environments where governance, accountability and regulatory oversight are fundamental. Whether driven by financial regulation, professional obligations, partnership governance requirements or tax authority scrutiny, firms are increasingly expected to understand where individuals are working, where decisions are being made and how associated risks are being managed.

However, cross-border workforce activity can often evolve outside established governance frameworks.

A senior executive spends increasing amounts of time overseas supporting regional operations. A partner joins the management board of a foreign office. A director takes responsibility for multiple jurisdictions. An investment team works remotely across several countries. A relationship partner regularly travels internationally to support key clients.

Individually, these arrangements may appear low risk and commercially sensible. Collectively, they can create tax, employment tax, National Insurance, regulatory and governance obligations that extend far beyond HR or mobility teams.

At the same time, tax authorities are becoming increasingly sophisticated in identifying cross-border activity through payroll reporting, immigration data, international information exchange and advanced analytics. HMRC has been clear that technology, structured data, artificial intelligence and enhanced compliance activity will play an increasingly important role in closing the tax gap and identifying risk. As a result, organisations should expect greater scrutiny of the information already available to tax authorities and greater focus on whether businesses can evidence effective governance and control.

The question is no longer whether activity can be identified. It is whether organisations can demonstrate they understand the associated risks and have appropriate controls in place.

The partnership dimension: often overlooked, increasingly important

Recent litigation involving BlueCrest Capital Management LLP provides an important reminder that governance structures, influence and decision-making authority can have significant tax consequences. While the case focused on the UK’s LLP salaried member rules rather than global mobility, it highlights issues that are highly relevant for international businesses: who makes decisions, where those decisions are made and how organisations evidence control, influence and governance.

The hidden complexity: remuneration, pensions and social security

For many financial and professional services firms, the greatest mobility challenge is not salary. It is remuneration.

Deferred bonuses, share awards, carried interest arrangements, co-investment structures, long-term incentive plans and deferred partner remuneration can follow individuals across borders, creating obligations that continue long after a move has taken place.

As a result, firms can face:

• Multi-jurisdictional payroll reporting obligations
• Double taxation risks for employees and partners
• Complex employer withholding requirements
• Income tax and National Insurance challenges
• Cost recharge and transfer pricing considerations
• Increased compliance risk across multiple years

For regulated firms, the position can be even more complex. Deferred remuneration, retention periods and clawback provisions may sit alongside tax and payroll obligations, creating additional governance and oversight requirements.

Pension and home social security arrangements and benefits can create an additional layer of complexity. Benefits that are tax-efficient in one jurisdiction may be taxed differently in another, while social security obligations do not always follow the same rules as income tax. Without appropriate oversight, organisations may face unexpected employer costs, employee concerns and historical compliance issues that can be difficult to unwind.

This is often where mobility risks become most interconnected, bringing together payroll, employment tax, reward, pensions, social security and governance considerations across multiple jurisdictions.

The risks are often more connected than they appear

One of the biggest governance challenges is that workforce mobility rarely sits neatly within a single function.

HR may focus on talent deployment and employee experience. Payroll teams focus on reporting obligations. Tax teams assess compliance risks. Finance teams manage costs. Risk and compliance teams oversee governance requirements. Business leaders prioritise commercial outcomes.

The reality is that cross-border workforce activity can affect all of these areas simultaneously.

For financial and professional services firms, mobility decisions can influence:

• Employment taxes, payroll and social security
• Remuneration and equity reporting
• Corporate tax and transfer pricing
• Permanent establishment risk
• Partnership and LLP taxation
• Governance, substance and regulatory obligations

A globally mobile executive, partner or director may appear to create a straightforward personal tax or payroll question. In practice, that same individual could influence transfer pricing arrangements, create corporate tax exposures, affect governance requirements within overseas entities and raise broader questions around operational substance.

For asset managers, private equity firms and investment businesses, the location of investment professionals and key decision-makers may also be relevant to questions around value creation, investment management activity and substance.

Looking at these issues in isolation can leave significant blind spots.

Five questions business leaders should be asking about mobility governance

For many organisations, mobility risks do not arise because the rules are unclear. They arise because responsibility is fragmented, workforce activity is difficult to track and risks are assessed in isolation.

Against a backdrop of increasing regulatory scrutiny, leadership teams should be asking five key questions.

1. Do we know where our people are working and are our controls designed for today’s workforce model?

Effective governance starts with visibility. Many organisations have robust processes for traditional assignments but less oversight of business travellers, remote workers, cross-border project teams and internationally mobile leaders. Without reliable data, it becomes difficult to assess tax, payroll, National Insurance and governance risks consistently.

2. Is ownership of mobility risk clearly defined and connected to our wider risk framework?

Cross-border workforce activity affects multiple functions simultaneously, including HR, tax, payroll, finance, legal and risk.

Leadership teams should understand who owns mobility risk, how significant issues are escalated and whether mobility is being assessed alongside broader tax, regulatory and operational risks rather than treated as a standalone compliance exercise.

3. Do we have sufficient oversight of internationally mobile leaders, partners and directors?

Senior individuals often create the greatest governance complexity because of the authority they hold and the decisions they make.

For financial institutions, law firms and professional partnerships, the location of key decision-makers can have implications extending well beyond personal tax compliance, including governance, substance, transfer pricing and regulatory considerations.

4. Are remuneration, pension and social security arrangements being reviewed as people move across borders?

For many firms, remuneration creates some of the most complex mobility challenges.

Deferred bonuses, equity awards, carried interest, deferred partner remuneration, pension contributions and social security obligations often continue long after a move takes place. Without coordinated oversight, organisations can face unexpected costs, reporting obligations and historic compliance exposures.

5. Could we demonstrate that our approach is appropriately governed and controlled?

Ultimately, this is the question regulators, tax authorities and other stakeholders are increasingly asking.

Organisations should be able to demonstrate:

• How mobility risks are identified and assessed
• Who is responsible for oversight and decision-making
• How tax, payroll, regulatory and governance risks are monitored
• How key decisions are documented and evidenced
• How mobility governance operates across HR, tax, payroll, finance and risk functions

The objective is not to eliminate risk entirely. It is to ensure risks are understood, appropriately managed and aligned with the organisation’s wider governance framework.

Mobility as an enabler, not a constraint

Financial institutions, law firms, accounting practices, consulting firms and other international partnerships will continue to rely on globally mobile talent to support growth, innovation and client service.

What is changing is the level of scrutiny applied to cross-border workforce activity and the expectation that organisations can demonstrate robust governance around it.

In an increasingly regulated and interconnected environment, effective mobility governance is becoming a competitive advantage.

For many organisations, global mobility is no longer simply an HR issue. It is a governance issue sitting at the intersection of tax, regulation, remuneration, partnership management and risk oversight. Those that can demonstrate visibility, accountability and effective decision-making will be better placed to support international growth while managing increasingly complex regulatory and tax expectations.
