The State Bank of India (SBI) has projected a modest ₹3,700 crore revenue loss to the central government in FY26 due to the latest Goods and Services Tax (GST) reforms, according to its recent research report. The reforms, approved by the GST Council at its 56th meeting, include a major rate rationalisation that replaces the existing four-tier structure with a simplified two-tier system—standard rates of 5% and 18%, and a demerit rate of 40% for select luxury and sin goods.
While the government had earlier estimated a gross revenue loss of ₹93,000 crore from GST rationalisation based on FY24 data, SBI’s analysis suggests that stronger consumption, improved compliance, and higher tax collections will significantly cushion the fiscal impact. The report positions the reforms as structural rather than stimulative, arguing that they will widen the tax base, reduce litigation, and enhance voluntary compliance.
🧭 GST Reforms: Key Structural Changes
| Reform Element | Previous Structure | Revised Structure | Impact on Revenue & Compliance |
|---|---|---|---|
| Tax Slabs | 5%, 12%, 18%, 28% | 5%, 18%, 40% | Simplifies compliance, reduces disputes |
| Essential Items | 12% | 5% or Nil | Boosts affordability, lowers inflation |
| Luxury/Sin Goods | 28% | 40% | Higher revenue from select categories |
| Services | Mixed rates | Standardised at 18% | Streamlines invoicing and reporting |
| Weighted Average GST Rate | 14.4% (2017) | 9.5% (2026 est.) | Reflects consumption-led tax efficiency |
The reforms are expected to reduce the effective tax burden on consumers while improving clarity for businesses.
🔍 Fiscal Impact Assessment: SBI vs Government Estimates
| Metric | FY24 Estimate | FY26 Projection | Commentary |
|---|---|---|---|
| Gross Revenue Loss | ₹93,000 crore | ₹1.11 lakh crore | Includes Centre and States |
| Net Revenue Loss | ₹48,000 crore | ₹25,794 crore | After accounting for consumption boost |
| Centre’s Share | ₹6,960 crore | ₹3,700 crore | Minimal impact on fiscal deficit |
| Fiscal Deficit Impact | — | ~1 basis point | Negligible macroeconomic effect |
SBI’s report emphasizes that the ₹3,700 crore loss is marginal and will likely be offset by increased tax buoyancy and economic growth.
📉 Inflation Moderation and Consumption Boost
The GST rate cuts on nearly 295 essential items—from 12% to 5% or Nil—are expected to reduce Consumer Price Index (CPI) inflation in this category by 25–30 basis points in FY26. Additionally, rationalisation in services could ease CPI inflation by another 40–45 basis points, leading to an overall moderation of 65–75 bps over FY26–27.
| Category | GST Rate Change | CPI Impact (bps) | Consumption Outlook |
|---|---|---|---|
| Essentials (Food, Pharma) | 12% → 5% / Nil | –25 to –30 | Higher affordability, rural demand surge |
| Services (Transport, Insurance) | Mixed → 18% | –40 to –45 | Simplified billing, increased uptake |
| Overall CPI Impact | — | –65 to –75 | Supports monetary policy and growth |
The reforms are expected to stimulate demand across FMCG, retail, healthcare, and transport sectors.
