Section 54 of the Income-tax Act, 2025 — Business of Prospecting for Mineral Oils (Special Deductions)

In plain language

What Section 54 is about

Section 54 of the Income-tax Act, 2025 is a special provision that lets oil and gas companies claim deductions for the heavy, high-risk costs of searching for and producing mineral oils (crude oil and natural gas) in India. It replaces the old Section 42 of the Income-tax Act, 1961 and works on the same principle: because exploration is enormously expensive and many wells turn out dry, the normal business-expense rules are not enough. Section 54 therefore allows deductions only to the extent, and in the manner, agreed in a contract with the Central Government (typically a Production Sharing Contract, or PSC).

Who it applies to

• Companies engaged in a "specified oil exploration business" — i.e. prospecting for, or the extraction or production of, mineral oils.
• Only where the Central Government has entered into an agreement with the assessee for the association or participation of the Government (or a person authorised by it) in that business.
• That agreement must have been laid before each House of Parliament. This is a strict eligibility gate — no qualifying PSC laid before Parliament, no Section 54 benefit.

What deductions are allowed

The deductions permitted are those specified in the agreement itself. Broadly they fall into three buckets:

• Abortive / infructuous exploration: expenditure on exploration in an area that is surrendered before the start of commercial production (money spent on a block that is given up). This is the classic "dry well" relief.
• Post-production drilling and exploration: after commercial production begins, expenditure (incurred before or after that date) on drilling or exploration activities, related services, or physical assets used in that connection.
• Depletion allowance: a deduction for the depletion of mineral oil in the mining area, allowed in the year commercial production begins and in the succeeding years specified in the agreement.

Crucially, the Supreme Court in CIT v. Enron Oil & Gas India Ltd. (2008) — decided under the old Section 42 but equally relevant here — held that an allowance is admissible only if it is specifically provided in the PSC. The contract, not the assessee's wish, defines the deduction.

How it interacts with other sections

• Instead of, or in addition to, normal allowances: the agreement can provide that Section 54 deductions apply in lieu of, or in addition to, the ordinary allowances under the Act (for example depreciation). You cannot double-count the same asset — physical assets already given depreciation are generally excluded from the drilling/exploration deduction.
• Transfer of the business or interest: if the business or an interest in it is transferred, any unallowed expenditure cannot be deducted again by the transferor in the year of transfer or later. Instead, the capital sum received is compared with the unabsorbed expenditure — a surplus is taxed (broadly as business income/capital gains as agreed) and a shortfall is allowed as a deduction.
• Amalgamation and demerger: where the transfer is under a scheme of amalgamation or demerger of Indian companies, the deduction passes to the successor company, which steps into the shoes of the predecessor and continues to claim the remaining allowances as if no transfer had occurred.

Practical implications for taxpayers

• This is a niche corporate provision — it matters to ONGC, Oil India, Reliance, Cairn/Vedanta, and other PSC/OALP contractors, not to individual salaried taxpayers.
• Meticulous contract-linked documentation is essential: every claimed deduction should be traceable to a specific clause of the Government agreement.
• Do not confuse this with Section 54 of the 1961 Act, which dealt with capital-gains exemption on sale of a residential house. Under the 2025 Act the numbering has changed — house-property capital-gains relief now sits in a different section. Section 54 of the 2025 Act is exclusively about mineral-oil prospecting.
