India's Parliament has passed the Mines and Minerals (Development and Regulation) Amendment Bill, stripping state governments of significant powers to levy taxes and royalties on mineral extraction within their territories. The passage of the legislation marks a decisive shift in the division of fiscal authority over India's mineral resources, moving key revenue-raising powers over mining from the states to the Union government.

What does the bill change?

The central change is fiscal. States that host mineral-bearing lands have historically relied on levies connected to mining activity as a source of revenue. The new legislation restricts their capacity to impose such taxes, consolidating that authority at the level of the Union.

For mineral-rich states, the practical effect is a narrowing of the tax base. Jurisdictions that have collected revenue from mining operations will need to reassess their fiscal planning in light of the restricted powers, and mining companies operating across state lines will face a more uniform — and centrally governed — fiscal regime for mineral extraction.

Who decided, and for whom?

Parliament, India's federal legislature, passed the bill. The legislation amends the existing framework governing mines and minerals, which already placed significant regulatory control over mineral development with the centre while leaving states with administrative and revenue functions. The newly passed amendment pushes that balance further toward central authority on the question of taxation.

The constitutional backdrop matters. India's Constitution divides legislative powers between the Union and the states, and mineral-rich states have long argued that royalties and mining levies fall within their fiscal domain. Litigation and legislative contest over this question have run for years. The amendment represents Parliament's latest — and most direct — assertion of central authority in this space.

What does the ruling change for practitioners?

For lawyers advising mining companies, the immediate task is to audit existing state-level tax exposure. Any levies that states can no longer impose following the amendment will be relevant to ongoing disputes, refund claims, and future fiscal structuring of mining operations. Counsel for state governments will be examining whether the restriction on taxing powers invites fresh constitutional challenge — a question of separation of powers between the Union and the states that Indian courts have addressed repeatedly in the mining context.

For in-house teams at mining operators, the change promises greater uniformity. A single central framework for mineral taxation reduces the compliance burden of navigating divergent state levy regimes. That benefit, however, comes with dependence on central rate-setting and policy, which may shift with future amendments.

The federalism question

The bill lands in the middle of a running constitutional debate over fiscal federalism in India. Mineral-bearing states — several of which are among the country's less industrialised economies — have argued that they bear the environmental and social costs of extraction and should retain the corresponding revenue powers. The Union position, reflected in the legislation, treats mineral resources as a national asset requiring uniform development and regulation.

The restriction on states' tax powers does not end the argument. States retain the option of challenging the legislation's provisions in constitutional litigation, and the Supreme Court of India has previously shaped the law in this area through its rulings on royalties, mining leases and the boundaries of state taxing authority. Practitioners expect the amendment to generate fresh litigation testing the limits of Parliament's power to curtail state levies in the mineral sector.

What comes next?

The bill, now passed by Parliament, will proceed through the remaining stages of the legislative process to become law. Once enacted, its provisions will govern the fiscal treatment of mineral extraction going forward, subject to any judicial challenge.

For the mining sector, the passage removes a measure of fiscal uncertainty — companies now know the direction of travel is toward central control of mineral taxation. For the states, the fight over mineral revenue moves to a new arena: the courts, and the political negotiation over fiscal transfers that typically follows any significant reassignment of taxing powers between levels of government.
