Tamil Nadu could create more than ₹1.20 lakh crore in additional annual fiscal capacity without imposing new taxes or taking on extra debt, according to an assessment by Kearney, a US-headquartered consulting firm. The assessment says the opportunity lies in improving revenue collection and managing government expenditure more effectively, rather than simply increasing the tax burden or borrowing to fund existing commitments.
The estimate is significant because it shifts attention from the familiar question of how much more a state can raise to the less visible question of how efficiently it converts economic activity into public revenue. Kearney’s assessment points to gaps in GST capture, alcohol taxation, property transactions, mineral royalties and the use of central government-funded schemes. It also links the revenue question to spending priorities, arguing that better collection and expenditure management could help Tamil Nadu pursue growth, welfare programmes and fiscal administration together.
The assessment is based on a mismatch between the scale of Tamil Nadu’s economy and the revenue it currently captures from some sectors. It says Tamil Nadu’s monthly per-capita expenditure is higher than that of Maharashtra, Karnataka and Gujarat, but the state’s GST revenue remains low when measured against its Gross State Domestic Product. The comparison suggests that consumption and economic activity are not translating into GST receipts at the same rate as in the state’s overall economic profile.
That gap is particularly visible in services. Services account for 53.60 per cent of Tamil Nadu’s economy, according to the assessment, but contribute only 37.80 per cent of the state’s GST collections. Kearney has therefore identified the monitoring of taxable services and stronger GST collection as one of the main areas where the state could improve revenue without introducing a new tax.
The numbers do not, by themselves, establish why the gap exists. A lower share of GST collections from services could reflect differences in the composition of the sector, the distribution of taxable and non-taxable activity, compliance levels, reporting practices or the way economic output is measured. The assessment, however, treats the difference as evidence that the tax administration is not fully capturing the service economy. That makes the issue administrative as well as fiscal: expanding revenue would require better visibility into transactions and more effective enforcement within an increasingly service-led economy.
The report also identifies the state’s alcohol market as a potential source of additional revenue. It recommends differentiated excise duties based on the price of alcoholic beverages and full monitoring of procurement and sales by the Tamil Nadu State Marketing Corporation, or Tasmac. The proposal concerns both the design of the tax and the management of the state-controlled retail system. Better tracking of volumes, prices and margins could alter the revenue generated from the same market, although the supplied report does not quantify the additional amount expected from these measures.
Property transactions are another area highlighted by Kearney. The assessment recommends adjusting guideline values when necessary to improve revenue from registration and stamp duty. It says this revenue stood at 0.72 per cent of Tamil Nadu’s Gross State Domestic Product in 2025-26, compared with 1.33 per cent in Maharashtra.
This comparison places property taxation within the wider fiscal geography of Indian states. Guideline values influence the value on which registration charges and stamp duty are calculated. If those values do not keep pace with transaction conditions in areas where property prices have risen, the state may collect less than the value of the underlying market activity would suggest. At the same time, the assessment does not provide details on regional variations within Tamil Nadu or explain how any adjustment would affect buyers, sellers and redevelopment activity.
For cities, this is an important institutional issue. Registration and stamp-duty revenue is linked to land markets, housing transactions, commercial property and redevelopment. A change in guideline values can affect the formal cost of buying or transferring property, while weak valuation can reduce the public revenue available for services and infrastructure. The assessment identifies the revenue opportunity but does not set out a detailed implementation framework or a timetable for revising values.
Mining and central government schemes form two further parts of the proposed revenue strategy. Kearney recommends accurate monitoring of the quantity of minerals extracted from mines and the royalties collected on them. It also calls for steps to ensure that Tamil Nadu receives the full amount available to it under central government funding schemes. In both cases, the emphasis is on improving the state’s ability to claim or collect money already associated with existing economic activity and public programmes.
These recommendations point to a common administrative problem: revenue performance depends not only on tax rates but also on measurement, data systems, compliance and coordination between departments. Monitoring mineral extraction requires reliable information about production and royalty liabilities. Securing the full benefit of central schemes requires the state to meet programme conditions, submit claims and use allocated funds within the applicable framework. The supplied assessment does not identify the specific schemes involved or quantify the funds that may currently be unclaimed.
The fiscal argument is therefore broader than a proposal to raise more money. It is about converting administrative capacity into usable fiscal space. Kearney says Tamil Nadu could create more than ₹1.20 lakh crore in additional annual financial capacity through improved revenue collection and expenditure management. The figure should be read as an assessment of potential, not as a confirmed budget receipt. The report, as described in the supplied material, does not provide a department-wise breakdown, implementation cost, collection timeline or independent validation of the estimate.
Expenditure management is the other half of the proposal. The assessment says the state would need to prioritise spending correctly alongside improving revenue collection. That matters because additional receipts do not automatically create room for new commitments if existing expenditure is poorly targeted or if funds are tied up in low-priority activities. The report links better expenditure management to the simultaneous pursuit of development, welfare and fiscal administration, but the supplied account does not specify which spending areas should be reduced, protected or reorganised.
For Tamil Nadu’s urban system, the implications are tied to how state finances support infrastructure and public services. Major roads, transport systems, water supply, housing programmes and other urban investments require sustained public spending. A state that improves its own-source revenue and secures a larger share of available central funding may have greater flexibility in financing such commitments. However, the assessment does not claim that the identified revenue measures will automatically produce better city services, nor does it establish how any additional fiscal capacity would be distributed between urban and rural areas.
The central tension is that several proposed measures could have effects beyond government accounts. Changes to alcohol excise structures may affect prices and the operating economics of Tasmac. Revised property guideline values may increase transaction costs or change the declared value of real estate transfers. Stronger GST monitoring could improve compliance while also increasing scrutiny of service businesses. More accurate mineral monitoring could raise royalty collections but would require effective oversight of extraction activity. The assessment identifies these areas as opportunities, while the available report does not provide a social or sectoral impact analysis.
The comparison with Maharashtra is also useful but limited. Tamil Nadu’s registration and stamp-duty revenue at 0.72 per cent of GSDP is presented against Maharashtra’s 1.33 per cent. That difference signals a possible revenue gap, but it is not a complete explanation of the two states’ fiscal performance. States differ in economic structure, property markets, administrative systems, urbanisation patterns and the design of their revenue instruments. The comparison is therefore best understood as a prompt for further examination rather than proof that Tamil Nadu can reproduce Maharashtra’s results through a single policy change.
What the assessment establishes is the existence of several potential revenue and efficiency levers: GST administration in services, differentiated alcohol excise, monitoring of Tasmac procurement and sales, property valuation, mineral royalties, access to central funding and prioritisation of expenditure. What remains unclear is how much each lever could yield, how quickly the gains could be realised and what institutional changes would be required.
The next stage will determine whether the ₹1.20 lakh crore estimate becomes a policy framework or remains a high-level assessment. For that to happen, the state would need to identify the relevant departments, publish the assumptions behind the estimate, separate recurring revenue from one-time gains and explain how any additional fiscal capacity would be allocated. Until those details are available, Kearney’s assessment is best read as a map of Tamil Nadu’s untapped administrative and fiscal capacity rather than a guaranteed increase in annual revenue.
