Section 465 Incapacitated child tax credit
(1) Where a claimant proves that he or she has living at any time during a year of assessment any child who-
(a) is under the age of 18 years and is permanently incapacitated by reason of mental or physical infirmity, or
(b) if over the age of 18 years at the commencement of the year, is permanently incapacitated by reason of mental or physical infirmity from maintaining himself or herself and had become so permanently incapacitated before he or she had attained the age of 21 years or had become so permanently incapacitated after attaining the age of 21 years but while he or she had been in receipt of full-time instruction at any university, college, school or other educational establishment,
the claimant shall, subject to this section, be entitled in respect of each such child to a tax credit (to be known as the“incapacitated child tax credit”) of €3,300.
(2)(a) A child under the age of 18 years shall be regarded as permanently incapacitated by reason of mental or physical infirmity only if the infirmity is such that there would be a reasonable expectation that if the child were over the age of 18 years the child would be incapacitated from maintaining himself or herself.
(b) A tax credit under this section shall be in substitution for and not in addition to any tax credit to which the individual might be entitled in respect of the same child under section 466.
(3) Where the claimant proves for the year of assessment-
(a) that the claimant has the custody of and maintains at his or her own expense any child who, but for the fact that that child is not a child of the claimant, would be a child referred to in subsection (1), and
(b) that neither the claimant nor any other individual is entitled to a tax credit in respect of the same child under subsection (1) or under any other provision of this Part (other than section 466A), or, if any other individual is entitled to such a tax credit, that such other individual has relinquished his or her claim to that tax credit,
the claimant shall be entitled to the same tax credit in respect of the child as if the child were a child of the claimant.
(4)(a) The reference in subsection (1) to a child receiving full-time instruction at an educational establishment shall include a reference to a child undergoing training by any person (in this subsection referred to as “the employer”) for any trade or profession in such circumstances that the child is required to devote the whole of his or her time to the training for a period of not less than 2 years.
(b) For the purpose of a claim in respect of a child undergoing training, the inspector may require the employer to furnish particulars with respect to the training of the child in such form as may be prescribed by the Revenue Commissioners.
(5) Where any question arises as to whether any person is entitled to a tax credit under this section in respect of a child over the age of 21 years as being a child who had become permanently incapacitated by reason of mental or physical infirmity from maintaining himself or herself after attaining that age but while in receipt of full-time instruction referred to in this section, the Revenue Commissioners may consult the Minister for Education and Science.
(6) Where for any year of assessment 2 or more individuals are or would but for this subsection be entitled under this section to relief in respect of the same child, the following provisions shall apply:
(a) only one tax credit under this section shall be allowed in respect of the child;
(b) where the child is maintained by one individual only, that individual only shall be entitled to claim such tax credit;
(c) where the child is maintained jointly by two or more individuals, each of those individuals shall be entitled to claim such part of such tax credit as is proportionate to the amount expended by him or her on the maintenance of the child;
(d) in ascertaining for the purposes of this subsection whether an individual maintains a child and, if so, to what extent, any payment made by the individual for or towards the maintenance of the child which the individual is entitled to deduct in computing his or her total income for the purposes of the Income Tax Acts shall be deemed not to be a payment for or towards the maintenance of the child.
