India’s mining sector just got a major legal update. Parliament has passed the Mines and Minerals (Development and Regulation) Amendment Act, 2026, bringing the biggest changes to mineral taxation rules in years.
The government introduced the Bill in the Lok Sabha on August 10, 2026. The Lok Sabha passed it on August 12, and the Rajya Sabha followed a day later, on August 13. Notably, both Houses cleared the legislation with almost no floor debate. The law now heads to the President for final assent before it fully takes effect.
Why This Law Exists
This amendment didn’t come out of nowhere. It’s a direct response to a Supreme Court ruling from 2024.
That year, the Court examined a tricky legal question. Does royalty collected on mining activity count as a tax? The Court said no, royalty is a contractual payment, not a tax. But the Court also made a second, more consequential finding: state legislatures do have the constitutional power to tax mineral rights.
That ruling opened the door for individual states to introduce their own taxes and cesses on mining activity. As a result, mining companies started facing a patchwork of different state-level levies. Investors found it harder to predict costs. So the Centre stepped in with this amendment to create one uniform, predictable system nationwide.
The Core Change: Limiting State Taxation Power
The amendment’s centerpiece is a brand-new provision, Section 9D, inserted into the original MMDR Act, 1957.
Under this new section, state governments can no longer impose fresh taxes, cesses, or levies on mineral rights or mineral-bearing lands on their own. This restriction applies no matter how the levy is calculated, whether by mineral quantity, mineral value, royalty amount, or any other method.
Instead, states can only introduce such levies within limits set by the Central government. In short, the Centre now holds the reins on mineral taxation policy nationwide, rather than each state setting its own rules.
Central Government Also Gains Control Over Mineral-Bearing Land
The amendment doesn’t stop at taxation. It also expands the Union’s regulatory reach.
Previously, the central government controlled mine regulation and mineral development under the original Act. Now, that control extends specifically to mineral-bearing lands too, meaning land that contains mineral content meeting government-defined criteria. The Centre will define exactly what qualifies as “mineral-bearing” through separate rules.
This matters constitutionally. Under India’s Constitution, mining falls under the Union List, giving Parliament primary authority here. States retain some power too, but only within limits Parliament sets. This amendment tightens that boundary further in the Centre’s favor.
More Flexibility for Mining Leaseholders
Not every change in this law is about taxation. Several provisions actually make life easier for companies already holding mining leases.
For instance, leaseholders can now add multiple minerals to a single existing lease, rather than needing separate approvals for each one. This saves time and cuts red tape considerably.
There’s also a notable incentive built in for critical minerals. If a leaseholder adds minerals like lithium, cobalt, nickel, graphite, gold, or silver to an existing lease, they won’t need to make any additional payment for that inclusion. For other, non-critical minerals, though, standard rules still apply. Leaseholders must pay the applicable royalty, and in cases involving auctioned mines, the usual auction premium too.
The law goes a step further by allowing leases for major minerals to also include minor minerals, such as building stone, gravel, and sand, with royalty determined separately for those additions.
Boosting Critical Mineral Exploration
Critical minerals get special attention throughout this amendment, and that’s not accidental.
Minerals like lithium, cobalt, and nickel power electric vehicle batteries, renewable energy systems, and advanced electronics. India currently imports a significant share of these materials, which creates supply-chain vulnerability. So the law expands the scope of mineral exploration funding, aiming to accelerate domestic discovery and development of these strategic resources.
Alongside this, the amendment removes the existing cap on how much mineral output captive mines can sell in the open market. Previously, captive mines, meaning mines linked to a specific end-use industry, faced restrictions on selling their surplus output. Lifting that cap should let more mineral output reach the broader market instead of sitting unused.
The Bigger Debate: Federalism Concerns
Not everyone views this law purely as a win. It has sparked genuine debate around fiscal federalism, the balance of financial power between the Centre and the states.
Mineral-rich states like Odisha, Jharkhand, and Chhattisgarh depend heavily on mining-related revenue. Critics worry that centralising taxation control could squeeze state finances, particularly in regions where mining forms a major part of the local economy. Supporters counter that a single, predictable tax structure will attract more investment overall, which could indirectly benefit these same states through job creation and industrial growth.
This tension between national economic efficiency and state-level fiscal autonomy isn’t new, but this amendment brings it back into sharp focus.
What Happens Next
With both Houses of Parliament having passed the bill, the next formal step is presidential assent. Once granted, the law comes into force, and the government will begin notifying detailed rules that determine exactly how each provision works in practice.
Until those rules arrive, several practical questions remain open, particularly around how “mineral-bearing land” gets defined and how much flexibility states retain for existing levies.

Frequently Asked Questions
It’s a law that amends the Mines and Minerals (Development and Regulation) Act, 1957, primarily to create a uniform, centrally-regulated system for taxing mineral rights and mineral-bearing lands across India.
It follows a 2024 Supreme Court ruling that confirmed states can tax mineral rights. To prevent inconsistent state-level taxes from creating uncertainty for the mining industry, the Centre introduced this law to standardise the rules.
It stops state governments from imposing new taxes, cesses, or levies on mineral rights or mineral-bearing lands, unless those levies fall within limits set by the Central government.
Yes, in several ways. It lets leaseholders add multiple minerals to existing leases, waives extra payment for adding critical minerals, and removes the cap on selling minerals from captive mines.
As of its passage by both Houses of Parliament, the law is awaiting the President’s assent, after which it will formally take effect.
Mineral-rich states worry that reduced control over mining taxation could shrink an important source of state revenue, raising broader questions about fiscal federalism.
