The travel of Goods and Services Tax (GST) implementation has entered a large caller signifier with the latest restructuring of taxation slabs, a determination expected to walk connected implicit ₹2 lakh crore successful taxation benefits to consumers. With this, the GST compensation cess stands abolished arsenic it merges with the regular tax, marking the extremity of an epoch of compensation nether GST. The determination is apt to boost section demand, and the consequent maturation successful gross whitethorn trim the expected gross loss. However, definite States consciousness that nary due estimation of this nonaccomplishment has been made, and that the existent nonaccomplishment could beryllium overmuch higher than projected. They are aggrieved that their request for compensation has been ignored.
Though studies amusement that GST implementation has mostly benefited each States done wide compensation mechanisms, the post-compensation taxation operation is expected to rise concerns successful immoderate of them. The cess and surcharge mechanics gives the Centre further leverage implicit the States. With important changes successful the fiscal argumentation scenery successful caller years, including the instauration of GST, which has efficaciously shifted taxation powerfulness from the States to the GST Council, determination is an expanding request to revisit the fiscal argumentation connected taxation sharing to unrecorded up to the rule of ‘cooperative federalism.’
Evolving taxation landscape
Fiscal argumentation successful India, peculiarly connected gross sharing betwixt the Union and State governments, is an evolving story. Article 246 of the Constitution (subject-matter of laws made by Parliament and by the legislatures of States) demarcates the areas of taxation powerfulness betwixt the Centre and the States nether the Union List and the State List, respectively, with residuary powerfulness reserved for the former. Using this residuary power, Parliament amended the Constitution successful 2016 done Article 246A for the levy of Service Tax. The taxation scenery changed with the instauration of the Service Tax done the 92nd Amendment, and further with the 101st Amendment, done which GST was launched successful July 2017.
For the archetypal time, GST introduced a destination-based taxation alternatively of an origin-based one, too allowing the Centre and the States to stock a communal taxation base. With GST being a contributor of important ain taxation gross to States, this caller authorities has led them to endure a important erosion successful their fiscal autonomy, arsenic the powerfulness connected taxation is shifted to the GST Council, wherever the Centre dominates the decision-making process.
As India is simply a multi-tiered government, plan asymmetry arises successful assigning resources and responsibilities betwixt the Centre and the States. Normally, the powerfulness to rise resources is mostly centralised for ratio and economical reasons. The expenditure responsibilities are decentralised for amended accountability and businesslike transportation of nationalist services. The resulting fiscal imbalances are corrected done re-assignment and redistribution, enabling the authorities astatine each level to bid resources to discharge its responsibility. Such an accommodation indispensable stay dynamic to code changes successful the fiscal landscape.
Role of Finance Commission
Articles 268 to 293 of the Constitution specify the Centre-State fiscal relations. The Finance Commission (FC) is constituted nether Article 280, which has been constitutionally assigned the task of determining transfers to each States. However, determination are grievances regarding the mode successful which the Central Finance Commission applies its tax-sharing criteria, which, according to immoderate States, penalise progressive ones. There are besides complaints of inconsistency among the Finance Commissions successful adopting criteria and applying comparative weights.
The Commission’s grants are supplemented by grants nether assorted Centrally Sponsored Schemes (CSS), Central Sector Schemes, and, earlier, by the Union Planning Commission (PC) grants, which ceased aft the abolition of the Planning Commission successful 2014. Article 282 provides for nonstop grants by the Union government, portion Article 275 provides for statutory grants done the Finance Commissions. Some States consciousness that the travel of funds done these channels is neither just nor transparent.
Falling devolution share
The earlier strategy of sharing idiosyncratic taxes was replaced by a planetary sharing principle, acknowledgment to the 80th Amendment that came into effect during the 11th Finance Commission (2000-2005). The Commission recommended 29.5% to the States retired of the proceeds of shareable Central taxes, which was steadily enhanced to 30.5% by the 12th Finance Commission, 32% by the 13th Finance Commission and 42% by the 14th Finance Commission. In presumption of Jammu and Kashmir having ceased to beryllium a State, the stock came down to 41%. However, contempt higher recommendations, the existent devolution to the States arsenic a percent of Gross Tax Revenue (GTR) has consistently fallen short (Table 1).

The shortfall is attributed to the ever-increasing cesses and surcharges, which are not portion of the shareable excavation of revenue. The cess and surcharge accounted for ₹3,86,440 crore arsenic per the Revised Estimates (RE) 2024-25. It is expected to beryllium ₹4,23,456 crore nether the Budget Estimates (BE) for 2025-26, excluding the GST compensation cess. States person been perpetually pressing for their merger with the shareable pool, a request the Union authorities has not accepted. This assets gives further leverage to the Centre successful managing its expenses implicit and supra its accustomed taxation share, arsenic the proceeds from cesses and surcharges often money the Central stock successful assorted schemes.
Dependence connected Central transfers
Central transfers inactive relationship for 44% of the States’ gross receipts. It ranges from 72% for Bihar to 20% for Haryana with 9 States — Haryana (20%), Telangana (21%), Gujarat (28%), Maharashtra (28%), Karnataka (31%), Tamil Nadu (31%), Goa (33%) Kerala (34%), and Odisha (41%) — getting little than the wide mean fig of 44%. This indicates dense dependency of States connected Central transfers and, to that extent, a compromise successful their fiscal autonomy.
A look astatine the proportionality of taxation gross shared betwixt the Centre and the States during pre- and post-GST periods reveals a wide trend: the powerfulness to levy taxes is getting centralised, portion the expenditure responsibilities connected the States are connected the rise (Table 2).

For the 5 years from 2012-13 to 2016-17, the pre-GST period, the Centre collected 67% of the full taxation revenue, portion the States collected 33%. During the post-GST play (2018-19 to 2022-23), the ratio remained unchanged. As for gross expenditure, the Centre incurred 47% and the States 53% successful the pre-GST era. During the post-GST period, the figures were 48% and 52%, respectively. Increases successful the Centre’s gross expenditure successful caller years are mostly attributed to the enlargement of CSS connected subjects that mostly autumn successful the domain of the States.
The expenditure commitments of the States are comparatively higher, arsenic they are liable for tackling the subjects of instrumentality and order, health, education, agriculture, and section self-government. As a result, States question powerfulness to cod higher taxation revenues, arsenic the contiguous fiscal argumentation of taxing powerfulness does not adequately code their requirements. Further, dense dependence connected Central transfers besides creates problems specified arsenic liquidity absorption and the fearfulness of governmental vendetta connected the Opposition-ruled States.
As a mode out, immoderate States suggest that the illustration of Canada beryllium followed wherever the national authorities collects 46% of taxation gross and spends 40%, portion sub-national governments cod 54% and walk 60%. Such a strategy gives much fiscal autonomy and flexibility to the States.
With rising nationalist aspirations and widening work gaps, States’ expenditure commitments are steadily increasing. GST instauration has altered the assets presumption of the States, successful summation to centralising the authorization to levy tax. The dense dependence of the States connected the Centre is creating friction, particularly successful the Opposition-ruled States. This is wherefore galore States and economists are calling for a restructuring of the taxation sharing rule to heighten the States’ fiscal autonomy.
Towards fiscal autonomy
States similar Tamil Nadu person appointed a committee to analyse Centre-State relations. It is against this backdrop that the proposal is being made to stock the taxation basal connected idiosyncratic income taxation (IT) betwixt the Centre and the States, connected the lines of the GST. For instance, the stock of Central taxation devolution to States arsenic per the 2025-26 Budget Estimates is ₹14,22,444 crore. If the idiosyncratic IT basal of ₹13,57,000 crore (BE 2025-26) is shared connected a 50:50 ground with States wherever taxation is collected, the Central taxation devolution stock to the States would efficaciously get reduced to ₹ 7,43,944 crore.
Alternatively, it is besides suggested to empower the States to apical up IT, without large changes to the existent strategy of levy and collection.
Such an statement would trim States’ fiscal dependence connected the Centre, amended liquidity, and let progressive States — which lend much taxation gross — to straight payment from their higher taxation base. The Centre volition inactive person important leverage successful assets sharing to close fiscal imbalances, if any, done Central schemes, grants and accustomed taxation devolution.
