3688.Sections 373 and 374 provide, in certain circumstances, for deductions from earnings for travel costs and expenses of a non-domiciled employee or of members of his family. The travel in question must end on, or during the period of five years beginning with a date that is a “qualifying arrival date” in relation to the employee. This paragraph contains provisions to ensure that the deductions may be given where the qualifying arrival date was before 6 April 2003, but the costs and expenses of the travel relate to the tax year 2003-04 or to a later tax year.
