India's recently implemented mining taxation reforms are expected to strengthen domestic iron ore supply and create policy certainty for the steel industry, according to sector experts. The Mines and Minerals (Development and Regulation) Amendment Act (MMDR) 2026, which came into effect on 22 August 2026, restricts individual states from independently imposing new mining-related taxes and cesses, with all levies now requiring adherence to central government guidelines. The amendment addresses concerns stemming from a series of Supreme Court rulings.
In July 2024, India's Supreme Court ruled that royalty payments by mining firms are distinct from taxes and represent payment for mineral extraction rights. The court also determined that state governments retain the power to impose their own taxes on mineral rights. A subsequent August 2024 ruling allowed state governments to demand previous tax dues from mining firms, but restricted claims to the period after 1 April 2005.
Following these rulings, individual states began imposing their own mining taxes, creating inconsistent taxation frameworks across different regions. The retrospective tax provision exposed mining companies to substantial liabilities, with some estimates valuing potential dues at 2 trillion rupees (approximately $20.9 billion). State-owned mining firm NMDC estimated its potential tax liability in Karnataka at about 158 billion rupees, depending on the outcome of Karnataka's proposed retrospective mineral tax legislation.
Arnab Kumar Hazra, chief of strategy and corporate affairs at Rashmi Group, an industrial conglomerate with divisions in iron and steel, ferro-alloys and power, highlighted the amendment's significance. "The recent amendment removes two very important things. One is uncertainty from your business models and two, the retrospective overhang, which after crores of investment, can completely jeopardise your economics," Hazra told Argus Media at an industry event in Kolkata.
Under the new amendment, mineral tax demands are invalid if states had not collected the tax before the law took effect on 22 August 2026. However, taxes or cesses already collected by state governments before implementation will not be refunded. This framework has strengthened confidence in the mining sector by establishing a more uniform tax structure, limiting states' capacity to introduce new levies and eliminating retrospective tax demands, according to market participants.
State-owned Steel Authority of India (SAIL) indicated that the reforms will increase iron ore availability in the domestic market, strengthening raw material security and reducing import dependence. "With improved viability and development of its captive mines, Sail will be able to make additional iron ore available for sale in the market, in accordance with the applicable regulatory framework," SAIL stated in a statement released last week. Industry experts anticipate that state governments will accelerate mine auctions to boost revenues following the amendment's implementation.
The reforms address a critical pain point for India's steel sector, where reliable access to domestic iron ore has been constrained by policy uncertainty and retrospective tax exposure.
