Tamil Nadu Records Highest Ever Revenue Deficit Of ₹78,324 Crore In FY26
Tamil Nadu has recorded its highest-ever revenue deficit of ₹78,324 crore in the 2025-26 fiscal year (FY26), surpassing the deficit recorded during the COVID-19 pandemic in FY21. According to an analysis of state data by Chennai-based Kearney senior partner Nithin Chandra, the fiscal deterioration has been driven by weaknesses in tax administration, systemic corruption, and revenue leakages.
Warning signs of this fiscal slide were visible in FY23 and FY24, but the state lacked an institutional mechanism to force a course correction. The analysis pointed to administrative issues, rather than structural constraints, as the primary drivers of the shortfall.
A key area of concern is the state's Commercial Taxes Department, where a government White Paper previously attributed GST shortfalls to systemic corruption. Additionally, stamp duty collections have stagnated despite Chennai, Coimbatore, and the KTCC corridor representing some of India’s most valuable property markets.
Since the 2021-22 fiscal year, Tamil Nadu’s stamp duty collections as a share of GSDP increased by just 0.03 percentage points. In comparison, Maharashtra saw an increase of 0.20 percentage points and Gujarat recorded 0.12 percentage points. This stagnation in Tamil Nadu has been attributed to outdated guideline values, registration delays, and significant revenue leakages.
Excise revenues also showed slower growth compared to peer states. Between FY22 and FY26, Tamil Nadu’s excise collections grew at a compound annual growth rate (CAGR) of 9.49%, while Karnataka grew at 11.66% and Maharashtra at 18.69%. Tamil Nadu's total excise collections stood at ₹11,836 crore, which is less than one-third of Karnataka’s ₹41,000 crore.
The state's mining revenue also remained low at ₹4,433 crore, falling below the potential generation capacity of its mineral resources.
While some argue that Tamil Nadu’s export-oriented economy—with merchandise exports of around $52 billion—results in lower GST collections because exports are zero-rated, the analysis indicates this is only a partial explanation. Efficient revenue administration should capture the second-order effects of exports, such as increased employment and local consumption, to expand the tax base.
To restore fiscal health, the analysis suggests plugging leakages and improving tax compliance rather than introducing new taxes. If Tamil Nadu had maintained its 2006-07 own-tax-to-GSDP ratio of 8.94%, it would collect approximately ₹1.23 lakh crore more in annual own-tax revenue, covering nearly 90% of the projected FY26 fiscal deficit.
