MMDR Amendment Act set to encourage fresh capital investment, bring tax uniformity
Parliament passed the Mines and Minerals (Development and Regulation) Amendment Act, 2026, aimed at creating a uniform and predictable fiscal framework for the mineral sector
The amendment restricts state governments from imposing taxes, cesses, or other levies on mineral rights and mineral-bearing lands beyond conditions prescribed by the Central Government
The reform is projected to unlock fresh capital investment, accelerate mineral exploration, and make domestic mineral production more competitive globally
The changes specifically target certainty in taxation for critical minerals important to clean energy, defence, and advanced manufacturing supply chains
The MMDR Act, 1957 — Legislative Framework for Mineral Regulation
The Mines and Minerals (Development and Regulation) Act, 1957 is the principal central legislation governing exploration, prospecting, mining, and regulation of minerals in India. It was enacted under Entry 54 of the Union List (regulation of mines and mineral development declared by Parliament to be expedient in the public interest), which allows the Centre to override state legislative competence over mines (a State List subject under Entry 23, but subject to Union control under Entry 54).
Key Details
- Enacted 1957, in force from June 1, 1958; amended multiple times — notably in 1999 (introduced reconnaissance operations), 2015 (introduced auction-based allocation of mining leases), and 2023 (opened exploration of critical/deep-seated minerals to private players and removed six minerals, including lithium and titanium, from the atomic minerals list)
- Mining is a State List subject (Entry 23) but Parliament can legislate under Entry 54 (Union List) when it declares such regulation "expedient in the public interest" — the basis for central override of state mineral levies
- The 2026 amendment introduces a new provision restricting states from levying taxes/cesses on mineral rights or mineral-bearing land except as conditioned by the Centre, addressing the fallout of a landmark Supreme Court ruling on state taxation powers over minerals
The 2026 Amendment Act uses the Centre's Entry 54 override to standardise the fiscal treatment of mining across states, directly targeting the inconsistency in state-level cesses that made investment planning unpredictable for mining companies.
Centre-State Fiscal Federalism in Mineral Taxation
Mineral-rich states have historically used their taxation powers (Entry 50, State List — "taxes on mineral rights subject to any limitations imposed by Parliament by law relating to mineral development") to levy cesses on mining activity, creating wide variation in the effective tax burden across states. This tension between state fiscal autonomy and the Centre's mandate to maintain a uniform national mineral market is a recurring theme in India's federal structure.
Key Details
- Entry 50 of the State List empowers states to tax mineral rights, but explicitly "subject to any limitations imposed by Parliament by law relating to mineral development" — meaning Parliament can cap or condition state mineral taxation through ordinary law
- Widely differing state cesses and levies were found to distort mineral costs across regions, raising logistics and transport costs and preventing a unified national mineral market
- The 2026 amendment is a case study in cooperative federalism being enforced through unilateral central legislation permitted by the Constitution's own text (Entry 50's built-in limitation clause)
The Act's tax-uniformity provision is a textbook application of Entry 50's limitation clause — Parliament using its constitutionally granted power to cap state mineral taxation to serve a national economic objective (capital investment, critical mineral security).
Critical Minerals and India's Resource Security Strategy
Critical minerals — inputs essential for clean energy technology, semiconductors, defence systems, and advanced manufacturing (e.g., lithium, cobalt, rare earth elements, titanium) — have become a strategic priority as India seeks to reduce import dependence, particularly from China, which dominates global critical mineral processing.
Key Details
- The National Critical Mineral Mission and the 2023 MMDR amendment identified 24 critical and strategic minerals (including lithium, niobium, and rare earth elements) for accelerated exploration and auction
- Six minerals — lithium, beryllium, niobium, titanium, tantalum, and zirconium — were removed from the "atomic minerals" category via the 2023 amendment, opening them to private-sector exploration and mining under the ordinary MMDR regime
- Predictable, uniform taxation is positioned as a precondition for attracting long-gestation, capital-intensive exploration investment in critical minerals
Tax uniformity under the 2026 amendment is explicitly linked to critical mineral security — investors are more likely to commit capital to long-horizon critical mineral exploration when the fiscal framework is stable and centrally predictable rather than subject to state-by-state variation.
- MMDR Act enacted: 1957; in force since June 1, 1958
- Legislative basis for Centre's override: Entry 54, Union List (mines and mineral development "in the public interest")
- State taxation power on minerals: Entry 50, State List (subject to Parliament's limitations)
- Prior major amendments: 1999 (reconnaissance operations), 2015 (auction-based leases), 2023 (critical minerals opened to private exploration; 6 minerals delisted from atomic minerals)
- New provision in the 2026 Act restricts state taxes/cesses on mineral rights and mineral-bearing land except as conditioned by the Central Government
