of that person includes the gross income derived from all
sources but where the person does not reside in Australia,
then subject to the extended meaning given to the word
"resident", the assessable income of that person includes
the gross income derived from all sources in Australia only,
it does not include the gross income derived from sources
outside Australia. The tax is assessable on gross income
received on an annual basis and is assessed on an annual basis.
The word "permanent" as used in paragraph (a) (i) of the
extended definition of "resident", must be construed as having
a shade of meaning applicable to the particular year of
income under consideration. In this context it is unreal to
consider whether a taxpayer has formed the intention to live
or reside or to have a place of abode outside of Australia
indefinitely, without any definite intention of ever returning
to Australia in the foreseeable future. The Act is not
concerned with domicile except to the extent necessary to show
whether a taxpayer has an Australian domicile, What is of
importance is whether the taxpayer has abandoned any residence
or place of abode he may have had in Avstralia. Each year
of income must be looked at separately. If in that year a
taxpayer does not reside in Australia in the sense in which
that word has been interpreted, but has formed the intention
to, and in fact has, resided outside Australia, then truly
it can be said that his permanent place of abode is outside
Australia during that year of income. This is to be contrasted
with a temporary or transitory place of abode outside Australia.
In any event the extended meaning of "resident" becomes relevant
only when, during the year of income under consideration, the
taxpayer does not reside in Australia. Paragraphs (a) (i) and (ii)
of the definition are complementary provisions enlarging the
group of persons who do not reside in Australia but become
liable to pay income tax in Australia.
