81E Enhanced deduction for eligible construction expenditure

Overview

This section provides for an enhanced corporation tax deduction for eligible construction costs incurred in respect of a qualifying apartment block.

Summary

Section 81E provides corporation tax relief, through an enhanced corporation tax deduction, to companies carrying out a property development trade in relation to the building of a qualifying apartment block, or refurbishing a building or structure such that it becomes a qualifying apartment block suitable for use as a dwelling.

Provided the necessary conditions are met, the enhanced deduction applies to completed developments for which a first commencement notice was lodged with the relevant local authority between 8 October 2025 and 31 December 2030.

To qualify for relief under this section, the construction costs must relate to the completed development in respect of which a claim for a deduction is sought. A relevant person must claim relief within 12 months of the end of the relevant accounting period. This is the accounting period in which the relevant certificate of compliance on completion in respect of a completed development is lodged with the local authority in whose functional area the development is located. A claim for the enhanced deduction should be made in the return filed under Part 41A in respect of that accounting period.

The enhanced deduction is subject to a maximum of €50,000 multiplied by the number of apartments in the completed development which is multiplied by the percentage of the completed development that is beneficially owned by the claimant (or deemed to be beneficially owned).

Subsection (4) provides that where—

  1. (4)(a) a relevant person has incurred eligible expenditure in respect of a completed development, and
  2. (4)(b) the relevant person is, in the computation of the amount of the profits or gains of a relevant property development trade or a qualifying trade, as the case may be, to be charged to corporation tax under Schedule D Case I for an accounting period, entitled to any deduction on account for that eligible expenditure in respect of the completed development,

then, the relevant person will, on the making of a claim, be entitled in the computation of the amount of the profits or gains of that trade for the relevant accounting period to a further deduction. In this section the further deduction will be referred to as an ‘enhanced deduction’. The amount of the enhanced deduction is equal to an amount determined under subsection (5).

Subsection (5) provides that, subject to subsections (6) and (7), the amount of the enhanced deduction in respect of a completed development is equal to the amount determined by the formula—

A x 25%,

where—

  • (5) A is the amount of the eligible expenditure incurred by the relevant person in respect of the completed development in respect of which the relevant person is entitled to a deduction in the computation of the amount of the profits or gains of a relevant property development trade or a qualifying trade, as the case may be, that is to be charged to corporation tax under Schedule D Case I for an accounting period.

It is noted that the amount of eligible expenditure must be incurred prior to the lodgement of the relevant certificate of compliance on completion but may be incurred at anytime before that date where it is in respect of the completed development.

Subsection (6) provides that the amount of the enhanced deduction in respect of a completed development shall not exceed the amount determined by the formula—

B x C x D

where—

  • B is the number of apartments in the completed development,
  • (6) C is €50,000, and
  • D is the percentage of the completed development that is beneficially owned by the relevant person, or in the case of a relevant person who is a relevant contractor is deemed, by virtue of subsection (3)(d), to be beneficially owned by the relevant person, on the relevant date (i.e. as at the date that the relevant certificate of compliance on completion in respect of the completed development is lodged with the local authority in whose functional area the development concerned is situated).

(7) Subsection (7) provides that that certain expenditure incurred by a relevant person in respect of a completed development will not be taken into account for the purpose of calculating the enhanced deduction. This includes where any eligible expenditure which –

  1. (7)(a) has been or is to be met, directly or indirectly, by grant assistance or any other assistance which is granted by or through the State, any board established by statute, any public or local authority or any other agency of the State,
  2. (7)(b) exceeds the amount that would be payable between independent persons acting at arm’s length in a similar transaction to that in respect of which the expenditure was incurred, or
  3. (7)(c) is incurred as part of a scheme or arrangement, where it is reasonable to consider that the main purpose, or one of the main purposes, is to avoid or reduce, the tax liability,

shall, when calculating the enhanced deduction in respect of a completed development, be excluded from the amount represented by ‘A’ in the formula in subsection (5).

(8) Subsection (8) provides that where expenditure is incurred by a relevant person in connection with construction operations in respect of both a completed development and a development that is not a completed development, such expenditure will be apportioned by the relevant person on a just and reasonable basis.

(9) Subsection (9) provides for the administration of the enhanced deduction.

(9)(a) Paragraph (a) provides that a claim under this section must be made by a relevant person within 12 months of the end of the relevant accounting period that the claim relates to. The claim should be made in the return filed under Part 41A, in respect of that accounting period.

(9)(b) Paragraph (b) provides the detail that the relevant person must provide when making a claim under paragraph (a). This detail to be provided are –

  1. (9)(b)(i) the eligible expenditure incurred in relation to the completed development and in respect of which the relevant person is claiming an enhanced deduction,
  2. (9)(b)(ii) the number of apartments in the completed development, and
  3. (9)(b)(iii) any other information the Revenue Commissioners may reasonable require for the purposes of this section.

(10) Subsection (10) provides for the treatment of eligible expenditure where a relevant person has claimed an enhanced deduction in respect of such expenditure and the expenditure was incurred as a debt by the relevant person and that debt is subsequently released.

(10)(a) Paragraph (a) provides that where in computing for tax purposes the profits of a relevant property development trade or a qualifying trade, as the case may be, an enhanced deduction has been claimed by a relevant person and, in computing that deduction, a debt incurred by the relevant person was included in the amount of eligible expenditure, then, if the whole or any part of that debt is thereafter released, an amount equal to the portion of the enhanced deduction which was determined based on the amount released is referred to as the ‘disallowed deduction’. The disallowed deduction is treated as a receipt of the trade arising in the period in which the release is effected.

(10)(b) Paragraph (b) provides that where paragraph (a) applies, and the trade concerned has been permanently discontinued, at or after the end of the period for which the enhanced deduction was claimed and before the release was effected, or is treated for tax purposes as if it had been so discontinued, section 91 will apply as if the disallowed deduction were a sum received after the discontinuance, i.e. treated as a post-cessation receipt taxable under Case IV of Schedule D.
