The Suvendu Adhikari government in West Bengal is targeting a significant improvement in the state's own tax revenue by closing systemic loopholes — particularly in the stone quarry and sand-mining sectors — rather than raising tax rates. According to a senior official in the state finance department, early results from these anti-leakage measures are already visible in revenue collection figures presented before the West Bengal Assembly during the ongoing budget session.

Mining Revenue Surges After Loophole Crackdown

Chief Minister Suvendu Adhikari disclosed in the Assembly on Tuesday that stone quarry revenue — largely concentrated in Birbhum district — averaged around ₹60 crore per year under the previous All India Trinamool Congress (TMC) regime. Since the new cabinet assumed charge on 9 May, the same source has already yielded ₹83 crore, a jump of over ₹23 crore within weeks.

The state government has attributed this surge directly to reforms in the e-challan system used at check-posts to levy taxes on trucks carrying sand from river beds. According to the finance department official, forgery in these e-challans was rampant under the previous administration, allowing mining and trading operators to avoid legitimate taxes by paying bribes to complicit officials instead.

E-Challan Forgery in Focus

The process to identify government officials involved in e-challan forgery has been initiated, the finance department insider said, and those found culpable will be replaced by officers with 'impeccable' track records. The e-challans, issued at check-posts to trucks transporting river sand, appeared legitimate on the surface but were reportedly manipulated to understate quantities or values, enabling systematic tax evasion.

'Now with such plugging of the loopholes it will be like killing two ducks with one stone. On one hand, the chain of illegal collection in the form of bribes in the system will be snapped, and at the same time the flow of revenue in the state's own tax system will automatically increase,' the state finance department official said.

Budget Proposals and the Single-Window Push

State Finance Minister Swapan Dasgupta presented the budget for 2026-27 on 22 June, which critics from certain quarters described as lacking specific directions on revenue improvement. However, the finance department insider argued that the real strategy is embedded in operational decisions taken since the cabinet's first day — not in headline budget announcements.

One significant policy move announced during the budget speech is the introduction of a single-window clearance system for all investment proposals of ₹100 crore and above. The stated aim is to ease the compliance burden on investors, but officials also see it as a mechanism to eliminate bribery that previously flourished in a fragmented, multi-department clearance process.

'There have been instances in the past of corruption in the process of getting multiple clearances to start a new business from various departments in a decentralised clearing system. However, when all clearances are granted through a single-window system, such scope for corruption will be eliminated,' the official said.

Broader Implications for West Bengal's Fiscal Health

West Bengal has historically struggled to grow its own tax revenue — the portion of collections that remain with the state rather than being shared with the Centre. By targeting leakages rather than rate hikes, the Adhikari administration is making a political as well as fiscal argument: that the previous TMC government allowed structural corruption to erode the exchequer.

This comes amid the ongoing budget session of the Assembly, where the government's fiscal credibility is under scrutiny. If the early gains in mining revenue are sustained and extended to other leakage-prone sectors, the approach could offer a template for states seeking to expand their fiscal base without imposing fresh burdens on taxpayers. The next few months will test whether these early numbers hold.
