    How we can help


To build and sustain your international growth, it’s important to get talented employees on-site, wherever they’re needed around the globe. How individuals work and travel in foreign locations can create a variety of corporate and personal tax/social security issues. These can be surprisingly complex and costly, draining significant resources within your Human Resources (HR), finance and operational departments. 

With our clients’ individual challenges at the forefront of our service, our global mobility service focuses on helping businesses attract and retain the best worldwide talent and move people cost-effectively and efficiently. We’ll work collaboratively with global organisations or companies exploring new territories for the first time, ensuring your compliance obligations are satisfied, giving you clear visibility of where your workforce operates and any exposure this brings, structure policy agreements to safeguard all parties and identify tax planning opportunities.  


Global mobility is changing. We live in a world where geography is no longer a barrier to prompt and effective service delivery. 

We see workforce challenges not as a burden to growth, but an opportunity to achieve competitive advantage. Setting a clear direction, which involves key stakeholders from the outset and is tailored to your specific systems and processes, enables us to provide effective ongoing support for your global mobility programme. 

Being aware of and planning for potential risks and exposure is paramount when operating internationally. We’ll be proactive in keeping you up to speed with current guidance and legislation across jurisdictions, to give you peace of mind.  


Our dedicated team of specialists use a blend of skills to support you throughout your organisation’s life cycle, from one-off projects through to complete management of your employment tax matters.  

We will:  

  • Prepare and submit reporting and calculations to overseas tax authorities and HMRC as required.  
  • Provide tailored advice and guidance for specific transactions to minimise cost and risk to the business. 
  • Be on hand to manage any queries raised by overseas tax authorities.  
  • Fully manage specific projects relating to legislation changes or case law outcomes. 
  • Collaborate with our Payroll and UK Employment Tax teams to address complex issues with your people, so we can design, implement and maintain the right strategies for you  
  • Be there to support you in new locations and provide practical advice to help you get up and running faster. 
  • Provide practical support covering a host of areas, from tax efficiency and compliance to strategic advice, all focused on helping you get the best value from your investment in people. 


By using our deep understanding of all aspects of global mobility, we can create effective policies and procedures that deliver both regulatory compliance and competitive advantage.  

We provide: 

  • Global tax compliance and advice, including US, Canada, Norway, Denmark, Netherlands, Azerbaijan & Malaysia  
  • An extensive affiliate network providing reliable and up to date information and guidance in other overseas locations  
  • Advice on HMRC administrative concessions to mitigate double taxation and aid cash flow  
  • Employee and employer memorandums on the implications of working in new locations  
  • National Insurance and Social Security advice 
  • Assignee management  
  • Tax briefings and reports for individuals or across assignee populations  
  • Worldwide Tax Return preparation and advice  
  • Tax policy advice  
  • Employee tracking and global payroll compliance through our suite of unique custom-built dashboards 


Our objective is to shift from the traditional model of reactive assignee selection to a more proactive, efficient and commercial solution, which adds value to your business by: 

  • Minimising tax and social security costs 
  • Giving early warnings and identifying travelling employees who trigger compliance risks 
  • Identifying potential visa and travel costs 
  • Providing you with an interactive dashboard technology on a real-time basis 
  • Paying employees accurately on time and every time, wherever they are in the world 
  • Assessing tax reporting and withholding obligations globally 
  • Producing valuable data and analytical data for mobility, HR and finance

AAB’s approach is unique, and we’ll work with you to reduce your risk with stress-free solutions to global mobility, so the biggest question becomes where to expand your business next. 

  • As a smaller sized business, it is a comfort to know that our payroll is being taken care of by the experts and we can concentrate on supporting other areas of our business.

    Barry R Moir, Superior-Wild Well Energy Services Limited

  • AAB set up Foreign Tax Net Credit Relief for us through HMRC, making it easier to get double taxation relief. They also educated our offshore workers on the implications and process of working overseas and how this affects their UK PAYE position.

    Bruce Melvin, READ Cased Hole Ltd

  • For me, business is all about relationships, and the quality of what the team at AAB do to support us is a fundamental lever for us as we strive to meet the challenges and succeed as a group through and beyond challenging times.

    John Walsh, Online Electronics Limited

  • The Corporate Finance team at AAB understood our business and led us towards concluding a tremendous deal. The team at AAB were thorough, proactive and efficient showing command and control of all the key elements of getting a deal done.
