Section 54F Exemption under New Section 112 Regime: Possible ITR Utility Computation Error (AY 2026-27)

The Finance (No. 2) Act, 2024 has significantly altered the manner in which long-term capital gains arising from land and building are taxed when such assets are transferred on or after 23 July 2024. While the statutory design attempts to safeguard eligible resident assessees through a “whichever is lower” comparison between two tax computation methods, there appears to be a technical gap in the present Government ITR Utility (and potentially in some private tax software) where Section 54F exemption is involved.

This write-up explains:

  • The new tax mechanism under Section 112 for long-term capital gains on land and building
  • How Section 54F exemption must legally be computed
  • Why using a single user-entered Section 54F exemption figure for both indexed and non-indexed methods can lead to incorrect tax computation
  • What changes are logically required in the ITR Utility and private software to align with the statute

1. New Long-Term Capital Gains Framework under Section 112

1.1 Tax rate of 12.5% without indexation

Post amendment by the Finance (No. 2) Act, 2024, where a land or building is transferred on or after 23 July 2024, long-term capital gains arising from such transfer are now subjected to tax at:

  • 12.5%, and
  • without applying indexation to the cost of acquisition or cost of improvement

This new regime is embedded in Section 112 and represents a departure from the traditional indexed 20% regime in respect of these specific assets and transactions.

1.2 Safeguard under second proviso to Section 112(1)(a)

Recognising that the denial of indexation could, in some situations, result in higher tax outgo, the legislature has built a protective mechanism specifically for resident individuals and HUFs.

The second proviso to Section 112(1)(a) stipulates that, for such eligible assessees:

The tax payable under the new 12.5% non-indexed method shall not exceed the tax that would have been payable if the computation was made under the earlier indexed method.

In essence, two computations are required:

  1. Non-indexed method (as per the amended regime) – LTCG at 12.5% without indexation
  2. Indexed method (as per the earlier approach) – LTCG at 20% with indexation

The assessee is liable only for the lower of the two tax amounts.


2. Nature of Exemption under Section 54F

2.1 Formula-based exemption – not equal to investment

Section 54F provides exemption from long-term capital gains where the net consideration from transfer of a long-term capital asset (other than a residential house) is invested in a new residential house within the prescribed time frame.

Critically, Section 54F does not grant exemption equal to the absolute amount invested. Instead, it follows a mandated formula:

Exemption = Capital Gain × Amount Invested ÷ Net Consideration

Key implications:

  • The exemption is directly proportional to the capital gain figure.
  • If the amount of capital gain changes, the Section 54F exemption must also recompute automatically in line with the statutory formula.
  • The exemption is therefore a derived figure dependent on the capital gain computation method.

2.2 Different capital gains under indexed and non-indexed methods

Under the amended Section 112, for qualifying resident assessees, two separate long-term capital gain figures will exist for comparison:

  1. LTCG without indexation – used for 12.5% tax
  2. LTCG with indexation – used for 20% tax

Since the capital gain amount forms the very base of the Section 54F formula, two different capital gain figures necessarily imply two different Section 54F exemptions when applying the law strictly as written.
