The Illusion of Booming GST Revenues: Dr. Arvind Subramanian
(a) 1 yr ago, govt re-labelled parts of GST (b) That created an optical illusion of booming receipts, while hiding a sharp decline in revenue performance (c) “Observers have been misled”
A Masterclass in Magic Tricks
In an illuminating piece titled “GST Re-labelling Misleads and Obscures,” former CEA Dr. Arvind Subramanian along with Abhishek Anand and Josh Felman, describe how “observers of revenue performance” (analysts, journalists, and general public) “have been misled.”
Starting in Sept 2025, the govt of India changed the labels on certain parts of the GST system. According to the authors, this “re-labelling” has led to two consequences:
(1) It creates an illusion of a booming growth in tax revenues, while hiding a sharp decline in actual revenue performance.
(2) It deprives state govts of about ₹15,000 to ₹20,000 crores every year from their fair share of the GST revenues.
How the Illusion Works
Imagine you have a ₹100 note in your left pocket and a ₹100 note in your right pocket. Now you move both notes into one pocket. Has your wealth doubled?
a. Before Sept 2025, the GST system had two main buckets: Regular GST and Compensation Cess (an extra tax on luxury or sin goods like SUVs & tobacco.)
b. Starting Sept 2025, the govt lowered GST rates on most items, and simplified the GST structure. The “Compensation Cess” was abolished in phases, while the items under that Cess were moved up from 28% GST rate to 40% GST.
c. Now in place of the abolished Cess, the govt introduced a new tax on these items called the Additional Excise Duty (AED).
d. In effect, the GST labels were changed. The old system was: “GST + large Cess”. The new system became: “Much bigger GST + smaller AED”.
Headline Numbers vs. Reality
a. The govt does not explicitly publish the data for the new Additional Excise Duty (AED). By obscuring this data, it becomes very difficult to compare the old GST numbers with the new ones.
b. The so-called massive surge in “GST” collections has occurred because a major portion of the old Compensation Cess is now labeled as “GST.” So, the GST bucket becomes fatter.
c. This moving money from one pocket to the other has been touted as a “Laffer Curve” phenomenon (“miraculous achievement”) where GST rates have been lowered, and yet tax collections have increased.
d. Headline vs. Actual GST Revenue Growth
Headline GST Growth
FY25: 9.4%
FY26: 7.5%
Q1FY27: 10.5% (Booming)
Actual GST Growth: Reality
FY25: 9.4%
FY26: 5.8%
Q1FY27: 4.9% (Declining)
IMPLICATIONS:
1. When you count ALL the taxes collected across all labels (GST + AED + old Cess), the total GST revenue growth in Q1 did not surge to 10.5%. It actually declined to 4.9%.
2. GST changes in Sept 2025 may have simplified and improved the system, but they have led to revenue losses.
The GDP Reality Check
To understand the economic conditions through the lens of tax revenue collections, you must look at net tax revenue (gross minus refunds), and then compare it against the GDP.
Since FY24, net GST revenues as a share of GDP have been steadily declining.
Net GST Revenues
FY24: 6.0% of GDP
FY25: 5.9% of GDP
FY26: 5.7% of GDP
Before the GST system was introduced in the country, the pre-GST average collection of indirect taxes was 6.2% of GDP. So, in terms of receiving revenue as a share of GDP, the govt is doing much worse in FY26 @ 5.7%.
The States are Hurting
a. When GST was designed, the Finance Commission’s formula meant that if ever the Compensation Cess was folded into the “Regular GST” structure, the states would receive 40% of the Central GST indirectly.
b. Reality: The Centre has completely changed the game under the new arrangements. The newly created Additional Excise Duty (AED) allows the Centre to keep a much larger slice.
c. The Centre has introduced a new tobacco machinery-related tax (“Health Security and National Security Cess”.) This is not shared at all with the states. The authors argue this seems to “legally” violate the GST law (“de jure”).
d. The Financial Hit: The authors estimate the entire act of re-labelling of taxes is depriving the state govts of ₹15,000 to ₹20,000 cr annually.
