A simpler mining tax model can mean more revenue for states

In September 1974, economist Arthur Laffer sketched an inverted-U graph on a napkin to illustrate a relationship between tax rates and government revenue. Governments that lower tax rates may actually boost total revenue, while tax rates that exceed a certain threshold could lead to reduced collections. This concept, known as the Laffer Curve, has been observed in various contexts.

India's recent passage of the Mines and Minerals (Development and Regulation) Amendment Act, 2026, is an example of applying this principle to taxation. The new legislation aims to streamline and simplify the taxation system for the mining sector, creating a uniform and predictable tax environment. By reducing the number of taxes, charges, fees, and levies from up to 14 to a simpler, more straightforward system, the Act hopes to attract investment, expand production, and develop downstream industries.

The Act retains the state's revenue pool from mineral production while establishing a cooperative federalism framework that enables states to grow stronger as part of one national economy. This move supports India's mining sector, which has undergone significant reforms over the past 12 years, attracting over Rs 7 lakh crore in revenue from both coal and non-coal sectors through royalty, auction premium, DMF, and GST.

As India moves from a system of untapped potential to one of transparency, competition, investment, and national purpose, a rational taxation policy becomes crucial. A predictable fiscal environment will help mineral-rich states realize the full value of their resources, conserve foreign exchange, strengthen supply chains, and reduce dependence on imports – all essential factors in a world of geopolitical uncertainties.
