(b)received a notice under section 8 of this Act requiring such a return,
shall, subject to subsections (2) to (5) below, within twelve months from the end of that year, give notice to the inspector that he is so chargeable, specifying each separate source of income.
(2)A source of income is excluded for the purposes of subsection (1) above in relation to any year of assessment if—
(a)all payments of, or on account of, income from it during that year, and
(b)all income from it for that year which does not consist of payments,
have or has been taken into account in the making of deductions or repayments of tax under section 203 of the principal Act.
(3)A source of income is excluded for the purposes of subsection (1) above in relation to any person and any year of assessment if all income from it for that year has been assessed or has been taken into account—

(b)in the making of deductions or repayments of tax under section 203 of the principal Act.
(4)A source of income is excluded for the purposes of subsection (1) above in relation to any person and any year of assessment if all income from it for that year is—
(a)income from which income tax has been deducted;
(b)income from or on which income tax is treated as having been deducted or paid (not being income consisting of a payment to which section 559 of the principal Act applies); or
(c)income chargeable under Schedule F,
and that person is not for that year liable to tax at a rate other than basic rate.
(5)A person shall not be required to give notice under subsection (1) above in respect of a year of assessment if and to the extent that his total income for that year consists of income from sources—

(6)If any person, for any year of assessment, fails to comply with subsection (1) above as respects any source of income, he shall be liable to a penalty not exceeding the amount of the tax for which he is liable, in respect of income from that source for that year, under assessments made more than twelve months after the end of that year.
(7)In the case of a partner, the reference in subsection (6) above to the tax for which he is liable in respect of income from any source does not include a reference to tax assessable in the name of the partnership on so much of the income from that source as falls to be included in the total income of any other person.”
