Short term business visitors: new guidance for employers
For employers with overseas workers who come to the UK for short periods, there is now guidance clarifying the tax implications and the steps to take.
HMRC has today published new compliance guidelines around short term business visitors (STBV), bringing together its expectations on the Income Tax and National Insurance treatment of overseas employees who visit the UK temporarily for work.
HMRC is clear that the publication does not introduce new law or policy, but it does provide the most comprehensive statement to date of what it considers to be good practice for managing short term business visitor (STBV) compliance.
Key messages for employers
No change in the rules, but increased focus on compliance
- The underlying tax and NIC rules remain unchanged.
- However, HMRC has brought together existing guidance, common errors and compliance expectations into a single document that is likely to become an important benchmark during employer compliance reviews.
Economic employer considerations remain a key risk area
- HMRC places significant emphasis on determining who is the true economic employer of an individual working in the UK.
- Businesses are reminded that recharging costs is only one factor and that consideration should also be given to who benefits from, supervises and controls the work being performed.
National Insurance should not be overlooked
- A notable feature of the guidance is the level of attention given to National Insurance. HMRC stresses that Income Tax and National Insurance are governed by different rules and that treaty relief for tax purposes does not determine NIC treatment.
- Employers should separately review social security agreement coverage and retain evidence supporting any decision that UK NICs are not due.
Robust tracking systems are essential
- The guidance reinforces the need for employers to have effective processes for identifying and tracking overseas employees visiting the UK.
- HMRC highlights poor tracking systems and insufficient records as common causes of non-compliance and expects organisations operating Appendix 4 arrangements to maintain adequate monitoring procedures.
Greater focus on governance and record keeping
- HMRC sets out detailed expectations around record retention, including evidence of UK workdays, travel history, remuneration, bonuses, share awards, expenses and NIC determinations.
- The guidance also contains a clear list of the errors HMRC most frequently encounters in practice.
What should employers do now?
In light of the new guidance, businesses with internationally mobile employees should consider reviewing their current STBV processes to ensure that:
- Visitor tracking arrangements remain fit for purpose
- Treaty relief claims are supported by appropriate analysis and documentation
- Economic employer assessments are robust
- National Insurance reviews are undertaken separately from tax reviews
- Sufficient records are retained to support the positions adopted
Our view
While HMRC’s new guidance (GfC19) does not change the technical rules, it provides a clear indication of the areas HMRC is likely to scrutinise during future compliance reviews.
Employers should view the publication as HMRC’s latest statement of expected operational controls and governance standards for managing short term business visitors.

Frequently asked questions: HMRC’s new short term business visitor (STBV) guidance
What is a short term business visitor (STBV)?
A short term business visitor (STBV) is typically an employee who is employed overseas but travels to the UK temporarily to carry out work duties. STBVs commonly include employees attending meetings, providing specialist support, overseeing projects, delivering training, or working with UK colleagues.
The tax and National Insurance implications depend on factors such as the individual’s UK workdays, residence status, applicable tax treaties, and the nature of their work. Employers are expected to identify and monitor these visitors appropriately to ensure compliance.
Why has HMRC issued new guidance on short term business visitors?
HMRC has published the guidance to clarify its compliance expectations and bring together existing rules, common errors and best practice in one place.
Although the guidance does not introduce new legislation, it provides a clear indication of how HMRC expects employers to manage STBV compliance. Businesses should view it as an important benchmark for governance, record keeping and risk management during future employer compliance reviews.
Do overseas employees automatically avoid UK tax if they spend only a short time in the UK?
No. A short UK visit does not automatically mean that UK tax is not due.
Many employers assume that limited UK workdays create an exemption, but entitlement to treaty relief depends on meeting specific conditions. Employers should assess each case individually and retain evidence supporting any position adopted. Incorrect assumptions about treaty relief are a common compliance risk.
What does HMRC mean by the “economic employer”?
The economic employer is the organisation that effectively receives the benefit of an employee’s work, regardless of who pays their salary.
HMRC’s guidance makes clear that salary recharge arrangements are only one consideration. Factors such as who directs, supervises and benefits from the work can also be important.
Economic employer assessments are particularly relevant when determining whether treaty relief may be available and are often a key area of HMRC scrutiny.
How does National Insurance differ from Income Tax for short term business visitors?
Income Tax and National Insurance contributions (NICs) are governed by different rules and should always be considered separately. A visitor may qualify for tax treaty relief yet still have UK social security obligations, depending on the applicable social security agreement and their circumstances.
Employers should not assume that a tax exemption automatically means UK NICs are not due and should retain documentation supporting their conclusions.
What records should employers keep for STBV compliance?
Employers should maintain detailed records that support both tax and National Insurance positions.
This may include UK workday calculations, travel history, payroll information, remuneration details, bonuses, share awards, expenses, treaty relief analyses, and evidence relating to social security coverage. Good records can help demonstrate compliance during an HMRC review and reduce the risk of disputes or assessments.
What happens if a business does not track overseas visitors properly?
Poor tracking can lead to missed tax obligations, inaccurate reporting and increased compliance risk.
HMRC specifically highlights inadequate tracking systems as a common cause of non-compliance. Without reliable data on UK visits and workdays, employers may struggle to determine the correct tax treatment, support treaty claims or defend their position during an enquiry. Effective visitor tracking is therefore a key governance requirement.
Which businesses are most affected by STBV rules?
Any organisation that sends employees into the UK or hosts employees from overseas group companies may be affected.
This includes multinational groups, technology companies, professional services firms, financial services businesses, manufacturers, life sciences companies and organisations with internationally mobile workforces. Even businesses or organisations with just one business visitor to the UK for one day have a compliance obligation and should review their procedures if overseas employees regularly perform work while in the UK.
When should employers review their STBV processes?
Employers should review their STBVs and supporting processes on a regular basis to keep a watchful eye on any changes and whether the processes in place are still effective.
The publication of the new guidance is a good opportunity to assess whether existing controls remain fit for purpose. Reviewing tracking systems, documentation procedures, treaty analyses and National Insurance processes can help identify gaps before they become compliance issues.
We have an Appendix 4 arrangement. Do we still need strong monitoring procedures?
Yes. Operating an Appendix 4 arrangement does not remove the need for robust oversight.
HMRC expects employers using Appendix 4 agreements to maintain effective monitoring procedures and accurate records. Businesses should be able to demonstrate how they identify relevant visitors, track UK workdays, assess eligibility for relief and support the positions reported through payroll and compliance processes.
