Arrivals in the UK
Normally where a short term business visitor is employed by, paid by or working for a UK company, PAYE must be operated in the usual way.
However, in certain circumstances, short term business visitors to the UK whose length of stay will not exceed 183 days, might make claims under the Dependent Personal Services Article (Article 15 or the equivalent). If such a claim is likely to be competent under a Double Taxation Convention, PAYE relaxations are possible where certain conditions are met.
