the proposition that the obligation to pay the tax was imposed by
that Act and was therefore an obligation of the testator. The
observations quoted by the learned Chief Justice of Western Australia
from the reasons given by me in that case were no more than an
expression of the view which I was then inclined to accept on a
question which, as I pointed out, it was not necessary to decide.
The question for decision in this case is whether the income tax
assessed against the respondent was a debt due by the testator
within the meaning of sec. 88 of the Act. The death of the testator
after making a return brought into operation sec. 62b of the
Assessment Act, which provides that, where a person dies after
1st July in any year and after furnishing a return of his income
for the preceding year, the Commissioner shall have the same powers
and remedies for the assessment and recovery of the tax from the
executor or administrator as he would have had against the deceased
person if he were alive. It seems to me that the effect of this
provision is no more than to substitute for the deceased person,
who, being dead, can no longer be a " taxpayer," his executor or
administrator, who then becomes a taxpayer within the meaning of
the Act. The Assessment Act of itself, apart from subsequent
legislation, imposed no obligation on any person to pay either
presently or at some future time any sum by way of income tax in
respect of the financial year 1923-1924. Until the Land Tax and
Income Tax Act 1923 was passed no income tax had been imposed
or rate of tax declared for that financial year, and it seems to me
to follow that until the passing of that Act no person was under
any obligation in respect of income tax for that year except, possibly,
the obligation to make returns required by the Assessment Act.
The Tax Act imposed the tax on the income chargeable of all
taxpayers. At the time when that Act became law the testator
was not and could not be a taxpayer, but his executor was a taxpayer
within the meaning of the Assessment Act, which is incorporated by
reference in the Tax Act. Accordingly it seems to me that the
effect of the Tax Act was to impose the obligation to pay income
tax for the financial year 1923-1924, not on the testator, but on the
executor. It may be that the obligation laid on the executor is an
