An eligible period means a period consisting of at least 365 days, which is either:
This is the simplest and easiest form of eligible period. If a seafarer leaves the United Kingdom to work abroad and at least 365 days later returns, an eligible period is achieved.
Section 378(3) permits an eligible period to be built up by adding together days spent abroad and days spent in the United Kingdom. A combined period is a period:
A day of absence is a day at the end of which the employee is absent from the United Kingdom. The end of a day for this purpose is midnight, see Section 378(4) and the case of Hoye v Forsdyke (55TC281). In general terms, a day of departure counts as a day of absence and the day of return does not. For more details see EIM33007.
Periods when an individual is non-resident may not be included
in an eligible period. Seafarers should be ordinarily resident in
the United Kingdom for the whole of the eligible period.
See
EIM33005 for guidance on how to approach
the problem of what is an eligible period.
