GST Collections Jump 18.1% in September 2026
Why in News?
- Net GST revenue, after refunds, rose 18.1% year-on-year to ₹1.77 lakh crore in September 2026, the fastest net growth in six months.
- The data was released on 1 October. Gross collections rose 14.7% to about ₹2.03 lakh crore.
- Domestic GST rose 10.1% to ₹1.38 lakh crore, and GST on imports rose about 26% to ₹65,525 crore.
- A year ago the 56th GST Council (3 September 2025) moved GST to two main slabs, 5% and 18%, plus 40% for luxury and sin goods.
- The RBI's Monetary Policy Committee meets on 5-7 October.
Key Terminologies
- Net GST Revenue
- GST left with the government after refunds to exporters and others are deducted; it shows the money actually retained, unlike the gross headline figure.
- Gross GST Collections
- Total GST collected before refunds, the monthly headline number, which can overstate what the exchequer finally keeps.
- GST 2.0
- The rate rationalisation from the 56th GST Council (3 September 2025): slabs of 5% and 18%, and 40% for luxury and sin goods, effective 22 September 2025.
- Like-for-Like Growth
- Growth worked out on a comparable base, so the same set of taxes is compared in both periods and a change in what is counted cannot inflate real growth.
Key Issues
- Comparison Base: The headline 14.7% looks stronger than the figure first reported for September 2025, when gross GST was ₹1.89 lakh crore, up 9.1%; against that number, ₹2.03 lakh crore is only about 7% higher, and Business Standard reported FY26 like-for-like growth at a five-year low of 5.57%.
- Import-Led Surge: GST on imports rose about 26% in September against 10.1% for domestic GST, and the RBI's August 2026 Bulletin put July's import GST growth at 28.8%, a rise that depends on trade values and prices as much as on domestic sales.
- State Divergence: Business Standard's analysis of FY26 data found 12 states with negative GST growth and 16 more with only single-digit growth, while Maharashtra, Karnataka, Gujarat, Tamil Nadu and Haryana together supplied over 40% of the total.
- Cess Cliff for States: The GST (Compensation to States) Act, 2017 guaranteed compensation until June 2022. The Centre then borrowed and extended the cess to March 2026 to repay it, and the 56th Council recommended removing it, leaving states without a dedicated cushion.
Key Implications
Positive/Pros/Merits
- Demand Signal: The RBI's August 2026 Bulletin called private consumption robust and noted the continuing impact of GST rationalisation in supporting urban demand, so rising net GST is a real-time marker of formal spending.
- Fiscal Headroom: Budget 2026-27 targets a fiscal deficit of 4.3% of GDP, down from 4.4% in the 2025-26 revised estimates, and steady GST inflows make that glide path easier to hold.
- Reform Validation: Net GST growth averaging about 14% in July-September against about 7% in April-June suggests the two-slab structure from the 56th GST Council is lifting volumes, even though the Centre projected a net revenue loss of about ₹47,000 crore from it.
- Revenue Momentum: Gross collections crossed ₹2 lakh crore for the third time in six months, after ₹2.43 lakh crore in April and ₹2.11 lakh crore in July, so the base is rising through the year and not only in festive months.
Negative/Cons/Demerits
- Refund Swings: Net revenue can move sharply on refunds alone; in September 2025 refunds rose 40.1% to ₹28,657 crore, which held net growth to 5% even as gross grew 9.1%, so part of this year's net jump reflects a low base.
- One-Month Reading: Net growth of about 7% in April-June against about 14% in July-September shows how uneven the series is, so a single strong month cannot prove the rate cuts permanently raised collections.
- Inflation and Policy Risk: A Business Standard poll of 2 October 2026 expects the RBI to raise the repo rate by 25 basis points as higher crude prices lift inflation risks, which would raise borrowing costs for the households and firms whose spending drives GST.
Key Initiatives
- GST 2.0 Rates: The 56th GST Council cut GST on many common items to 5% and moved small cars and motorcycles up to 350cc from 28% to 18%, effective 22 September 2025.
- Simplified Registration: From 1 November 2025, low-risk applicants get automated approval within three working days. The Finance Ministry expects about 96% of new applicants to benefit.
- GST Appellate Tribunal: Notification No. 18/2024 - Central Tax of 7 May 2026 empowered the Principal Bench to hear appeals, effective 1 April 2026.
- Enforcement Reform: The GST Council meeting on 7 October 2026 is expected to consider ending direct arrest powers, requiring judicial authorisation, and raising the prosecution threshold to Rs 5 crore.
The Government's approach is to lower rates, simplify registration and open a dispute forum, while accepting a projected net revenue loss of about ₹47,000 crore. The GST Council meets on 7 October 2026 and is expected to consider easing enforcement.
Director's Perspective
Way Forward
- Compare the 14.7% and 18.1% growth figures on a like-for-like base before treating them as proof, and read the original September 2025 figures alongside them.
- Track net GST revenue through the October-December festive quarter, since one strong month cannot show whether the two-slab structure has lifted compliance and spending together.
- Read state-wise GST growth every month, because the 12 states with negative FY26 growth are where demands for compensation-style support will come first.
- Set GST beside the RBI's monthly consumption indicators to separate genuine domestic demand from import-driven growth.
September's rise is real but smaller than the headline suggests. Measured against the figure first reported for September 2025, gross collections are about 7% higher, not 14.7%, and lower refunds and an import surge lift the net number further. The two-slab reform has clearly improved momentum, but one month cannot prove lasting buoyancy. In a Mains answer, conclude that GST 2.0 is lifting volumes, while the base problem, uneven state gains and the end of compensation show the reform is still incomplete.

Frequently Asked Questions
Why is net GST growth (18.1%) higher than gross growth (14.7%)?
Net revenue is gross collections minus refunds, so it moves with refunds as well as sales. In September 2025 refunds jumped 40.1% to ₹28,657 crore, which kept that month's net figure low and makes this September's comparison look stronger.
What is GST 2.0?
GST 2.0 is the rate rationalisation recommended by the 56th GST Council meeting on 3 September 2025 and effective from 22 September 2025: two main slabs of 5% and 18%, a 40% slab for luxury and sin goods, and a plan to end the compensation cess.
Does one strong month prove the GST reforms worked?
No. Net growth was about 7% in April-June and about 14% in July-September, and Business Standard reported FY26 like-for-like growth at 5.57%, so several months of comparable data are needed.
