New HMRC Guidance on Short-Term Business Visitors: What Your International Clients Need to Know
HMRC has published guidelines for compliance (GfC) 19 to help UK employers who have overseas workers performing duties in the UK on a short-term basis to comply with their UK tax obligations. This timely update addresses a gap that many accountants and HR professionals have grappled with, particularly as cross-border work becomes routine for many UK businesses.
Why This Matters Now
The rise of remote work, secondments and short-term project assignments means more UK employers are hosting overseas staff than ever before. Understanding the tax implications is critical: failing to apply the correct treatment can expose your clients to penalties, back-tax assessments and compliance errors.
GfC 19 is specifically designed to help UK employers navigate the tax rules for short-term business visitors.
Key Practical Points for Your Clients
The guidance clarifies the tax position when an overseas employee, contractor or consultant performs duties temporarily in the UK. The key distinction turns on residency status and the duration of UK presence. A "short-term business visitor" may be outside the scope of UK PAYE and employment taxes if they meet certain conditions—but the rules are fact-dependent and require careful analysis.
For accountants advising multinational groups, recruitment agencies placing overseas workers, or businesses hosting consultants from overseas parent companies, this guidance provides essential clarity. It should help practitioners avoid common pitfalls: treating visiting workers as UK-resident for tax purposes when they are not, or overlooking deemed-employment rules where they do apply.
Immediate Action Points
Your compliance checklist should now include:
- Obtaining employment contracts and residency evidence from overseas workers before they arrive in the UK, to establish their tax position.
- Reviewing any existing secondments or placements lasting more than a few months to confirm the correct tax treatment was applied.
- Communicating with clients' HR teams to ensure visiting workers are correctly classified on payroll systems.
HMRC's GfC 19 guidance is available on the HMRC website and should be reviewed carefully alongside the existing rules in the Income Tax (Employment) Regulations 2003 and relevant treaty provisions, where an overseas employee's home country has a tax treaty with the UK.
Broader Context
This guidance sits within HMRC's wider drive to modernise tax administration. On 21 July 2026, James Murray MP was appointed Financial Secretary to the Treasury, and ministerial responsibility for HMRC transferred to the Financial Secretary to the Treasury from the Exchequer Secretary to the Treasury. With fresh leadership in place, HMRC continues to publish practical guidance aimed at helping compliant taxpayers navigate an increasingly complex international tax landscape.
Next Steps
If you advise clients who frequently host overseas workers or are involved in cross-border secondments, review the new GfC 19 guidance without delay. Where you identify past compliance gaps, consider whether voluntary disclosure or an amended return is needed. This guidance is a welcome step towards clearer, more accessible rules—but as always, the facts of each case matter. Verify treatment against the specific circumstances before advising clients.
