Short-term business visitors to the UK: Are you meeting your tax obligations?

International business travel is routine, but even a brief UK visit can create tax obligations. HMRC’s Guidelines for Compliance, published on 13 August 2026, bring together its view of PAYE, Income Tax and NIC rules, record keeping and common errors, and businesses with internationally mobile employees should review whether their processes remain fit for purpose.

What is a short-term business visitor?

A short-term business visitor is broadly someone who normally works overseas but temporarily performs duties in the UK, including meetings, training, client work, business development or project assignments. There is no general exemption for a brief visit: UK duties can, in principle, be taxable from the first UK workday.

Why can a short visit create PAYE obligations?

A short visit can create PAYE obligations because UK duties may be taxable from the first UK workday, even where the employee is normally based overseas.

Treaty relief may reduce or remove the final UK tax liability, depending on UK days, employer residence, and whether remuneration is borne by a UK entity or permanent establishment, but it does not automatically remove the employer’s PAYE responsibilities. A UK host may still need to operate PAYE, unless an appropriate HMRC arrangement applies.

HMRC offers two special arrangements that can reduce the administrative burden. One broadly applies where treaty relief means no UK Income Tax should ultimately be due; the other can allow PAYE to be operated on a modified basis for certain taxable short-term visitors, where normal payroll operation would be impracticable.

NICs must be considered separately. A social security agreement or domestic NIC rules may apply, with evidence needed where overseas social security continues.

Where do employers commonly go wrong?

HMRC highlights several recurring errors made by employers:

• Assuming a short visit means there is no UK tax or PAYE exposure.
• Failing to track UK days and workdays or test treaty conditions each year.
• Overlooking intercompany recharges or other UK-borne remuneration costs.
• Misunderstanding the rules that can apply to short visits, or assuming the NIC position automatically follows the Income Tax position.
• Missing reporting for bonuses, benefits or employment-related securities.

Record keeping matters

HMRC expects sufficient evidence to support the treatment adopted, including UK duties and workdays, travel and employment records, remuneration and benefits, intercompany recharges and NIC documents. PAYE records generally need to be kept for at least three years from the end of the relevant tax year.

There may also be VAT to recover

International business travel can create a tax compliance burden, but it can also create recovery opportunities. Employees visiting the UK commonly incur VAT on hotels, conference costs, professional fees and other business expenditure. Overseas businesses may, subject to the relevant conditions, be able to recover UK VAT through the UK’s refund scheme for overseas businesses.

The same issue arises in the other direction. UK businesses sending employees overseas may incur foreign VAT that cannot be reclaimed through a UK VAT return. Depending on the country, local refund procedures may allow some of that VAT to be recovered. For EU VAT incurred by UK businesses, this will generally involve the relevant 13th Directive refund process.

These claims are often missed because the refund process sits outside normal VAT compliance, local rules differ and deadlines can be strict. Businesses with regular cross-border travel should therefore consider VAT recovery alongside their employment tax review rather than treating the two processes separately.

Questions employers should be asking now

• Do we know which overseas employees are performing duties in the UK, and for how long?
• Are we tracking UK workdays accurately enough to support the tax treatment?
• Have we checked whether treaty relief is actually available and who ultimately bears the remuneration cost?
• Where relevant, do we have an appropriate HMRC arrangement in place to manage PAYE obligations?
• Are NIC and social security considered separately from Income Tax?
• Are we capturing expenses and VAT in a way that allows legitimate refund claims to be identified?
