Arrivals in the UK
When an employee arrives in the UK, you must decide
Whether a cumulative tax code should be applied
What further action must be taken
This depends on
Why the employee has come to the UK
What the employee is going to do in the UK
How long the employee intends staying in the UK
Obtain this information if the arrival in the UK was in a tax year before you were informed of the arrival through an enquiry or return for the income for that year.
(*If the employee is still living abroad but works both in and outside the UK write to the employee for any information you need.)
If the individual is within SA and a letter for the required information has not been able to be issued in the tax year of arrival, it may still be sent if a return for the tax year of arrival has not yet been issued.
