The introduction of the Goods and Services Tax in July 2017 represented one of the most significant fiscal reforms in independent India's history. While it promised a unified national market and simplified tax compliance, the GST system also fundamentally reshaped the balance of fiscal power between the Union government and individual states.
The Pre-GST Landscape
Before GST implementation, India operated under a dual taxation system where states enjoyed substantial fiscal autonomy. State governments could levy various indirect taxes including Value Added Tax on intra-state sales, entertainment tax, luxury tax, entry tax, and purchase tax. This gave states considerable flexibility in adjusting tax rates based on local economic conditions and revenue requirements.
The Union government meanwhile controlled customs duties, central excise, and service tax. This clear demarcation meant states had direct control over significant revenue streams and could independently decide their fiscal policies within their jurisdictions.
What Changed Under GST
The GST subsumed multiple state and central taxes into a single unified tax structure. States surrendered their power to levy VAT, entertainment tax, luxury tax, and several other levies. In return, they received a share of SGST collections within their borders and a portion of IGST revenues on interstate transactions.
The critical institutional change came through the GST Council, a constitutional body where tax rates and policy decisions require consensus building. The Council includes the Union Finance Minister as chairperson and state finance ministers as members. Decisions typically require a three-fourths majority weighted by voting power, with the Centre holding one-third voting share and states collectively holding two-thirds.
The Compensation Mechanism
Recognizing that states might face revenue losses during the transition, the GST framework included a compensation guarantee. States were promised compensation for any revenue shortfall below a projected 14 percent annual growth rate for five years until June 2022. This compensation was funded through a cess on luxury and demerit goods.
However, the compensation mechanism became contentious, particularly during the COVID-19 pandemic when collections plummeted. Several states faced delayed compensation payments, raising questions about the reliability of Centre-state fiscal arrangements.
Loss of Fiscal Flexibility
States now find themselves with limited ability to independently adjust tax rates in response to local needs. If a state faces a natural disaster or economic crisis requiring immediate revenue mobilization, it cannot unilaterally increase tax rates on goods and services. Any rate change requires GST Council approval, involving negotiations with the Centre and other states.
This constraint becomes particularly significant during economic downturns. Previously, states could tweak tax rates on select commodities to boost revenues. Under GST, they must wait for Council meetings and build consensus, reducing their responsiveness to fiscal emergencies.
Revenue Dependency Concerns
States have become more dependent on timely GST settlement transfers from the Centre. The monthly SGST and IGST settlement process means states rely on efficient central administration and revenue sharing mechanisms. Delays in settlements directly impact state budgets and their ability to fund essential services.
Additionally, the compensation cess ended in June 2022, leaving states to manage with their share of GST revenues alone. Many states, particularly manufacturing-heavy ones like Tamil Nadu and Maharashtra, have argued that their revenue growth remains below the promised trajectory.
The Petroleum and Alcohol Exception
One significant carve-out remains: petroleum products and alcohol for human consumption stay outside GST purview. States retain the power to tax these items independently, providing them some fiscal autonomy. However, this creates market distortions and contradicts GST's goal of a unified national market.
Looking Ahead
The ongoing debate about GST and fiscal federalism centers on finding the right balance. Proponents argue that a unified market requires centralized tax policy, preventing states from engaging in harmful tax competition. Critics contend that reduced state autonomy undermines the federal principle and makes states less accountable to their own citizens for revenue decisions.
Several states have called for revisiting the GST structure, seeking either higher guaranteed compensation, greater flexibility in rate decisions, or expanded state-specific taxation powers. The coming years will likely see continued negotiations over the federal-state fiscal relationship.
The GST experience demonstrates the inherent tension in India's federal structure between national economic integration goals and state fiscal autonomy. How this balance evolves will significantly impact both India's economic growth trajectory and the nature of its federal democracy.
