Here's the question worth actually testing rather than assuming: when officials point to record e-way bill generation as evidence of a "more formalised" Indian economy, are they describing new economic activity joining the tax net for the first time, or the same broadly formal economy simply being tracked in far greater granular detail than before? Cross-referencing e-way bill volume against GST registration growth over the last eight years gives a fairly clear answer, and it's more nuanced than either the government's press releases or the skeptics' dismissals usually allow.
The Core Question: New Formalization or Better Tracking of the Same Base?
If e-way bill volume and GST registration counts were both measuring the same underlying phenomenon, informal economic activity converting into formal, tax-visible activity, you'd expect the two series to grow at broadly similar rates over time. They haven't. One has grown modestly and steadily. The other has grown explosively, especially in the last five years. That divergence is the whole story.
The Genuine Formalisation Shock: GST's First 18 Months
There's a specific, well-documented event worth separating from everything that came after. Economic Survey 2017-18, presented by then Finance Minister Arun Jaitley, found that as of December 2017, five months after GST's July 1, 2017 rollout, India had 9.8 million (98 lakh) unique GST registrants, an increase of over 50%, roughly 3.4 million net new unique taxpayers, compared to the old indirect tax system once double- and triple-counted registrations across excise, VAT, and service tax were properly adjusted for. That Survey chapter, titled "A New, Exciting Bird's-Eye View of the Indian Economy Through the GST," remains one of the most credible pieces of evidence that GST's launch mechanism itself, particularly the input tax credit chain that pressures even small suppliers to register so their business customers can claim ITC, genuinely pulled previously unregistered entities into the formal tax net.
By October 2018, total taxpayer count had crossed 1.14 crore, built on a base of roughly 64 lakh taxpayers migrated from the old regime at GST's launch. That's the real, one-time formalisation jump, and it happened almost entirely in GST's first 15 months.
What Happened After: Registration Crawls, Transaction Volume Explodes
Here's where the two series start telling different stories. GST's active taxpayer base grew from roughly 1.14 crore in October 2018 to about 1.53 crore by June 2025, per GSTN's own "8 Years of GST" statistical report, and stood at approximately 1.51 crore active GSTINs by January 2026. That's growth of roughly 33-34% over seven-plus years, a compound annual growth rate in the low-to-mid single digits, a perfectly respectable trajectory, but nothing like a continuing formalisation wave.
E-way bill volume tells an entirely different story over almost exactly the same period. Monthly generation hit a pandemic-driven record low of just 8.6 million bills in April 2020, recovered to a then-record 7.12 crore (71.2 million) in March 2021, and has since climbed to an all-time high of 13.84 crore in December 2025, with June 2026 generation at 13.68 crore, up 14.5% year-on-year from June 2025's 11.95 crore. That's nearly a doubling of monthly transaction volume in under five years, a growth rate several multiples faster than the registered taxpayer base over the same window.
| Metric | Earlier Anchor | Recent Anchor | Growth |
|---|---|---|---|
| Active GST taxpayers | 1.14 crore (Oct 2018) | 1.51-1.53 crore (2025-26) | ~33-34% |
| Monthly e-way bill volume | 7.12 crore (Mar 2021 record) | 13.68-13.84 crore (2025-26) | ~92-94% |
Registration figures from GSTN's "8 Years of GST" report and GSTN dashboard data reported through January 2026; e-way bill figures from CEIC-compiled GSTN data and Ministry of Finance releases through June 2026. Treat exact percentages as directional given rounding across differently-dated snapshots.
A Worked Calculation: Bills Generated Per Registered Taxpayer
Dividing transaction volume by registrant count gives a rough intensity measure, how much trackable activity the average registered taxpayer is generating, and it's a more original way to see the same divergence.
2026 window: June 2026's 13.68 crore bills against roughly 1.51 crore active taxpayers (Jan 2026 figure) works out to approximately 9.1 bills per registered taxpayer per month.
On this rough measure, per-taxpayer transaction intensity has more than doubled over five years, even as the taxpayer base itself grew by only about a third. That gap, transaction volume per registrant rising far faster than the registrant count itself, is the clearest available signal that most of today's e-way bill growth reflects existing formal businesses being tracked more granularly, not a continuing wave of previously informal players newly entering the system.
Challenging the Assumption: What's Actually Driving the Volume Explosion
Three concrete mechanisms explain most of the gap between registration growth and transaction growth, and none of them require assuming large numbers of new entities joined the formal economy.
- Progressive e-invoicing mandates. Mandatory e-invoicing, introduced for businesses above ₹500 crore turnover in October 2020, was progressively extended down to much smaller turnover thresholds through 2021-2024. Each threshold reduction pulls transactions from already-registered mid-sized businesses into the same digital tracking infrastructure that generates e-way bill data, inflating volume without adding a single new taxpayer.
- Removal of physical checks and rising digital trust infrastructure. Physical verification of goods in transit was removed at GST's very rollout in July 2017, and the system has continued moving toward automated, data-driven verification since. The Economic Survey around Budget 2026 explicitly recommended a "trusted dealer" framework, where compliant taxpayers face fewer physical checks and more certainty, which is itself a tell: policy focus has shifted from onboarding new registrants to refining trust tiers within the already-known base.
- Growing formalisation of logistics itself, not just the underlying trade. More third-party logistics operators, e-commerce fulfilment networks, and organised warehousing mean the same volume of goods movement is now more likely to generate a trackable e-way bill than it would have in 2018, when informal transport arrangements were more common even for otherwise GST-compliant sellers.
What's Still Genuinely Outside the Net
None of this means India's informal economy has shrunk to a marginal share. Roughly half of India's GDP and the large majority of its workforce still sit in the informal economy, according to widely cited estimates referenced in recent fiscal policy commentary, with cash-intensive sectors and small, sub-threshold enterprises remaining largely outside both GST registration and e-way bill tracking entirely, since e-way bills are only triggered for consignments above ₹50,000 in value moving between registered or trackable parties. A large share of India's smallest retail and service transactions simply never generates the kind of paper trail either metric can see, regardless of how sophisticated the tracking of the formal segment becomes.
What This Means Going Forward
First, expect the government's own communication to keep leaning on e-way bill records as a headline formalisation indicator, since it's genuinely the most responsive, high-frequency data series available, but expect analysts to increasingly caveat this by looking at registration growth alongside it, exactly the cross-check this piece runs.
Second, watch whether the "trusted dealer" trust-tier framework floated around Budget 2026 actually rolls out at scale. If it does, expect e-way bill volume to keep climbing even faster relative to registration growth, since reduced friction for compliant, already-known taxpayers tends to increase the volume of transactions they're willing to route through fully documented channels rather than informal alternatives.
Third, the real test of genuine continuing formalisation will show up in registration data, not transaction data. If active taxpayer counts start growing meaningfully faster than the roughly 4% annual pace of the last several years, particularly among smaller, sub-₹40-lakh-turnover entities that aren't currently required to register, that would be a much stronger signal of new formalisation than any further e-way bill volume record.
Frequently Asked Questions
Does rising e-way bill generation mean India's informal economy is shrinking?
Not necessarily on its own. Rising volume is at least as consistent with the existing formal economy being tracked more granularly through e-invoicing mandates and digitised logistics as it is with genuinely new informal businesses joining the tax net.
How many businesses are currently registered under GST in India?
Approximately 1.51 to 1.53 crore active GST taxpayers as of late 2025 and early 2026, according to GSTN's own statistical reporting.
When did India's e-way bill system launch, and how big is it now?
The e-way bill system launched in April 2018; monthly generation has grown from a low base to over 13.6 crore bills a month by mid-2026, an all-time high of 13.84 crore was recorded in December 2025.
Why did e-way bill generation crash in April 2020?
The COVID-19 lockdown brought goods movement across India to a near-standstill, and monthly e-way bill generation fell to a record low of roughly 8.6 million that month, a useful reminder that the metric genuinely tracks real economic activity rather than just paperwork volume.
