Mines Amendment Bill 2026 threatens Tamil Nadu's ₹2,265 crore mineral tax revenue, warns MP Vaiko
Synopsis
Key Takeaways
Lok Sabha MP and Marumalarchi Dravida Munnetra Kazhagam (MDMK) leader Durai Vaiko has warned that the Mines and Minerals (Development and Regulation) Amendment Bill, 2026, poses a direct threat to Tamil Nadu's fiscal autonomy and could disrupt a key revenue stream worth over ₹2,265 crore annually. The warning came on 15 August after Vaiko met Tamil Nadu Finance Minister Maria Wilson in Chennai to brief her on provisions of the legislation that he argues curtail the taxation powers of state governments.
What the Bill Does
The Bill, passed by the Lok Sabha on 12 August and the Rajya Sabha on 13 August, introduces a new Section 9D that restricts state governments from levying taxes on mineral rights and lands containing minerals. According to Vaiko, this provision could prevent states from collecting revenue and outstanding dues amounting to lakhs of crores of rupees — a sweeping rollback of fiscal powers that states had only recently exercised.
The Supreme Court Ruling at the Centre of the Dispute
The conflict has a direct constitutional backdrop. A nine-judge Bench of the Supreme Court ruled in 2024 that states hold the authority to impose taxes on mineral-bearing lands. Acting on that judgment, the Tamil Nadu government enacted the Tamil Nadu Mineral Bearing Land Tax Act, 2024, framed the relevant rules in 2025, and began collecting the tax from 4 April 2025. Critics argue the new central amendment effectively nullifies a Supreme Court-backed state right.
The Revenue at Stake
The financial exposure is significant. Of the ₹4,395.68 crore in total revenue generated by Tamil Nadu's Department of Geology and Mining during 2025-26, ₹2,265 crore — more than half — came from mineral-bearing land tax alone. If the amendment takes effect, this revenue stream could be severely disrupted, straining the state's fiscal position.
Opposition's Pushback in Parliament
Vaiko said he and other Opposition MPs personally met Union Coal and Mines Minister G. Kishan Reddy and urged the Centre to refer the legislation to the Parliamentary Standing Committee for detailed scrutiny. They also demanded consultations with state governments before the Bill was taken up for passage. Vaiko had separately submitted an amendment to Lok Sabha Speaker Om Birla seeking the deletion of Section 9D to protect state taxation powers. The Union government, however, passed the Bill in both Houses without what the Opposition described as a comprehensive debate.
What Happens Next
Vaiko urged Finance Minister Maria Wilson to press the Centre to protect Tamil Nadu's financial rights and initiate appropriate legal action. Wilson reportedly assured him that the government led by Chief Minister C. Joseph Vijay would take suitable steps. The dispute is likely to escalate into a broader federal confrontation, with other mineral-rich states potentially joining Tamil Nadu's challenge to the amendment.
