When you are looking to grow your business, you may look overseas for new opportunities.
You may choose for your employees to travel to the UK to build client relationships and support cross-border operations.
However, you may not realise that UK Pay As You Earn (PAYE) obligations can arise if your employee carries out duties there.
Where employees perform substantive work in the UK, they may be treated as Short Term Business Visitors (SBTVs).
You must have a clear understanding of what this means and your PAYE obligations to avoid any unexpected tax or penalties.
When do PAYE requirements arise for STBVs?
If your employee carries out work in the UK, PAYE obligations can arise from day one.
Even if they remain employed and paid by an overseas entity, they could be at risk.
HMRC will look beyond the contractual position and apply a concept of the economic employer.
This means they will look at who directs the employee’s work, who benefits from it and who bears the employment costs and risks.
Even if your employee is exempt from UK tax under a Double Taxation Agreement (DTA), PAYE must be operated unless an HMRC-agreed easement is in place.
When are you exempt from the SBTV requirements?
The SBTV obligations do not apply to all workers and treaty relief may be available if:
- An employee is tax resident overseas
- They spend fewer than 183 days in the UK within a relevant 12-month period
- The UK entity does not bear the employment costs or act as the economic employer
If these conditions are met, your business can apply to HMRC for an Appendix 4 STBV agreement.
An Appendix 4 agreement removes the requirement to operate PAYE in real time.
Instead, you must track your employee’s UK workdays and submit an annual report by 31 May following the end of the tax year.
HMRC also operates a limited 60-day concession. This means that some employees spending fewer than 60 UK workdays in a tax year may qualify for PAYE relaxation.
However, strict conditions apply and HMRC may consider linked periods across tax years, so careful review is required.
What is the difference between Appendix 4 and Appendix 8 for SBTV?
Appendix 4 replaces real-time reporting with annual reporting requirements and eases your administrative burden when managing frequent short visits.
However, if an employee is employed by an overseas branch of a UK company or comes from a non-treaty jurisdiction, treaty relief does not apply.
This is where an Appendix 8 arrangement may be appropriate.
This allows you to settle PAYE annually for employees with 60 UK workdays or fewer in the tax year instead of processing payroll for each visit.
How should you manage SBTV obligations?
With increased data sharing between HMRC and border authorities, tracking your employee’s UK business visits accurately is crucial.
You should have clear processes in place to:
- Monitor UK workdays
- Review cost recharge arrangements
- Assess economic employer status
Annual reporting deadlines, particularly for 31 May submission date for Appendix agreements, must be carefully managed.
Failure to operate PAYE correctly can lead to unexpected tax liabilities, interest, penalties and increased scrutiny during HMRC reviews or corporate transactions.
