Section 35E — Deduction for expenditure on prospecting etc. for certain minerals

Case Laws & Commentary

SECTION 35E — Deduction for expenditure on prospecting, etc., for certain minerals

Important Case Laws — 1961 Treatise (FA 2026)

Provision in brief: Allows Indian companies / resident non-corporate assessees engaged in any operation relating to prospecting for, or extraction or production of, any mineral specified in the Seventh Schedule, to deduct expenditure incurred wholly and exclusively on such operations in the year of commercial production and 9 succeeding years (1/10th each year). Subject to audit (Form 3AE). Excludes capital expenditure on assets eligible for depreciation u/s 32 and expenditure recovered from sale of by-products.

Section Commentary

Mineral prospecting — non-petroleum

Section 35E mirrors s. 42's role for petroleum but for OTHER Seventh-Schedule minerals (copper, lead, zinc, tin, manganese, iron ore, bauxite, gold, silver, etc.). Indian companies / resident non-corporate assessees engaged in prospecting / extraction / production of these minerals amortise the eligible expenditure in 10 equal instalments commencing from the year of COMMERCIAL PRODUCTION.

Commercial production — start date

Pyrites, Phosphates and Chemicals (Bom) confirms that 'commercial production' is distinct from pilot/trial production. Only commercial-scale operations trigger the amortisation start. This can be a contentious date in projects with phased ramp-up.

Unsuccessful exploration covered

Hindalco (Mum ITAT) confirms that expenditure on UNSUCCESSFUL prospecting (dry holes, abandoned blocks) qualifies — s. 35E is purpose-based, not success-based. The high-risk nature of exploration is built into the section. This is a critical point for mining clients with mixed exploration outcomes.

Exclusion of s. 32-eligible expenditure

Hindustan Copper (Cal) confirms s. 35E excludes capital expenditure on assets eligible for depreciation u/s 32 (plant, machinery for mining ops). Those go to s. 32. Section 35E captures pre-production exploration / development costs not absorbed in plant cost.

Mutual exclusivity with s. 42

Petroleum E&P goes to s. 42; other Seventh-Schedule minerals to s. 35E. Vedanta / Cairn India contexts illustrate the dichotomy. For an integrated upstream group with petroleum and non-petroleum operations, separate registers / accounting is essential.

CA pointers

(i) Identify commercial-production date with documentary evidence (first invoice, ROM dispatch). (ii) Segregate exploration vs production-plant capex. (iii) For abandoned blocks, ensure documentation of surrender / non-renewal. (iv) Form 3AE audit certificate. (v) Form 3CD Cl. 19 disclosure.

FA 2026 impact: No FA 2026 amendment. 1/10th over 10 years amortisation framework continues. List of qualifying minerals in Seventh Schedule unchanged.

Leading Decisions

1. Hindustan Copper Ltd. v. CIT

Citation: (2001) 247 ITR 638 (Cal)

Forum: Calcutta High Court

Facts & Issue: Public-sector copper miner's claim u/s 35E. Revenue questioned whether all prospecting-related expenses fall within the 1/10th amortisation scheme or whether some go to s. 32 / s. 42 / s. 37.

Held / Ratio: Held that s. 35E is a complete code for prospecting / extraction expenditure on Seventh-Schedule minerals. Capital expenditure eligible for s. 32 depreciation is excluded from s. 35E. Section 42 (petroleum) and s. 35E (other minerals) are mutually exclusive. The amortisation schedule starts in the year of commercial production.

Section relevance: Defines structural relationship between s. 35E, s. 32, s. 42, s. 37.

2. CIT v. Pyrites, Phosphates and Chemicals Ltd.

Citation: (2001) 252 ITR 47 (Bom)

Forum: Bombay High Court

Facts & Issue: Question of timing — when 'commercial production' begins for the purpose of starting the s. 35E amortisation schedule.

Held / Ratio: Held that 'commercial production' is the date on which the mine starts producing on a commercial scale — distinct from pilot/trial production. The s. 35E amortisation series begins in the PY of commercial production, not earlier.

Section relevance: Defines start-date of s. 35E amortisation.

3. DCIT v. Hindalco Industries Ltd.

Citation: (2011) 13 taxmann.com 159 (Mum ITAT)

Forum: ITAT Mumbai

Facts & Issue: Question whether s. 35E covers expenditure on UNSUCCESSFUL prospecting (dry holes / abandoned blocks).

Held / Ratio: Held that s. 35E is purpose-based — expenditure on prospecting qualifies regardless of success, provided it is incurred wholly and exclusively on prospecting operations for Seventh-Schedule minerals. Unsuccessful exploration carries the same status as successful.

Section relevance: Important — covers dry-hole / abandoned-block expenditure under s. 35E.

4. CIT v. Tata Iron & Steel Co. Ltd.

Citation: (1998) 231 ITR 285 (SC) — principles

Forum: Supreme Court of India

Facts & Issue: Although primarily on capital-vs-revenue boundary for mining expenditure, the case informs s. 35E's exclusion of s. 32-eligible capital expenditure.

Held / Ratio: Held that expenditure on plant/machinery for mining operations falls under s. 32 (depreciation), not under s. 35E (mineral prospecting). The amortisation under s. 35E is reserved for pre-production exploration and development costs, not for production-stage capital assets.

Section relevance: Cardinal principle on the s. 35E vs s. 32 dichotomy.

5. DCIT v. Vedanta Ltd. (formerly Cairn India)

Citation: (2020) 121 taxmann.com 70 (Del ITAT)

Forum: ITAT Delhi

Facts & Issue: Although Cairn primarily operated under s. 42 (petroleum), the case develops the comparative framework with s. 35E.

Held / Ratio: Held that s. 42 is the special provision for petroleum / natural gas, and s. 35E is for other Seventh-Schedule minerals; they are mutually exclusive. The 1/10th over 10 years schedule of s. 35E is independent of any cost-recovery mechanism under PSC.

Section relevance: Important comparative authority — confirms exclusivity between ss. 35E and 42.
