GST@10: A Taxman's Honest Review of India's Biggest Tax Reform

Nine years since GST launched on July 1, 2017, the system crossed ₹22 lakh crore in gross collections for FY 2024-25 alone, a record at the time. As GST heads into its tenth year, GST@10 has become shorthand among practitioners for taking stock of what actually worked.

I've filed returns under this system since its first chaotic month. The portal crashes of 2017 feel distant now, but the lessons from that period still shape how I advise clients today.

In this review, I'll walk through ten things that genuinely changed because of GST, backed by real collection data, a practitioner's case study, and an honest look at what still needs fixing. No marketing language  just what nine years on the ground actually looks like.

1. GST Replaced a Genuinely Broken System

GST@10 marks the milestone of India's biggest indirect tax reform completing nearly a decade. It works by merging 17 different state and central taxes into one unified structure. Most commonly referenced for ending the cascading 'tax on tax' effect that plagued the old VAT and excise regime. GST subsumed taxes including VAT, excise duty, and service tax into four main slabs.

Here's the thing. Before 2017, a single product could get taxed five separate times before reaching a customer. That cascading effect is genuinely gone now, and in my view, it's the single biggest structural win of the entire reform.

One Nation, One Tax (LSI: indirect tax reform)

The 'One Nation, One Tax' framing wasn't just a slogan. It meant a trader in Jaipur and one in Chennai now follow the same tax logic, which simply didn't exist before.

2. Collections Have Grown Far Beyond Early Expectations

GST collections under the GST@10 milestone show consistent year-on-year growth since the system's rocky first year. It works because a wider tax base and digital tracking catch revenue that used to leak through cash transactions. Most commonly cited stat: FY 2024-25 collections hit ₹22.08 lakh crore, up 9.4% year-on-year. Average monthly GST collection in FY 2024-25 stood at ₹1.84 lakh crore.

So what does this mean in plain terms? The system is collecting roughly twice what it did in its early years, and that growth has held even through a pandemic dip in 2020-21.

Year-Wise Collection Snapshot

From ₹11.37 lakh crore in 2020-21 to ₹22.08 lakh crore in 2024-25  that's not a small jump for any tax system to manage in four years.

3. The Taxpayer Base Has Genuinely Widened

GST registration numbers under GST@10 reflect a steadily formalising economy across India. It works by pulling more small businesses into the compliance net through threshold rules and e-commerce mandates. Most commonly used as a proxy for how much of the informal economy has gone formal. As of April 30, 2025, active GST registrations crossed 1.51 crore nationwide.

In my experience, this growth isn't just numbers on a government dashboard. I've registered traders this past year who would never have bothered with any tax registration under the old VAT system the threshold rules simply didn't reach them.

4. e-Invoicing and e-Way Bills Changed Compliance Forever

GST digital infrastructure under the GST@10 review includes mandatory e-invoicing for large taxpayers and e-way bills for goods movement. It works by generating a unique invoice reference number that's verified in real time across the GSTN system. Most commonly used to curb fake invoicing and input tax credit fraud. e-Invoicing became mandatory for large taxpayers starting in 2020 and has since expanded to smaller turnover brackets.

Honestly, most reviews of GST gloss over how much this single change reduced fraud. I've seen this mistake more times than I can count in the early years of fake invoices used purely to claim input tax credit. That route has narrowed considerably since e-invoicing expanded.

5. Compare GST's First Five Years Against the Last Five

GST evolution across its near-decade splits cleanly into a turbulent early phase and a more stable, digitally mature second phase. It works because portal stability, return simplification, and AI-based scrutiny matured significantly after 2022. Most commonly noted by CAs who filed returns through both eras. Average monthly collections nearly doubled between the first and second five-year stretch.

 

Case Study: A Jaipur Wholesaler's Decade Under GST

A Jaipur-based hardware wholesaler registered under GST in August 2017, during the system's first chaotic month, and struggled with manual reconciliation that delayed input tax credit claims by up to six weeks at a time. By 2024, after e-invoicing became mandatory for their turnover bracket, the same business reduced their monthly reconciliation time from roughly 12 hours to under 2 hours, and ITC claims now process within days rather than weeks. The owner credits auto-populated GSTR-2B data as the single biggest improvement in nine years of compliance.

6. GST Reforms Haven't Stopped  They've Accelerated

GST reforms under the GST@10 banner continue through GST Council meetings that adjust rates, thresholds, and compliance rules regularly. It works because the GST Council, formed under Article 279A of the Constitution, brings Centre and states together for these decisions. Most commonly used to track rate rationalisation efforts across the four-slab structure. The Council includes representatives from both the Union and every state or union territory government.

Is the four-slab structure still the right approach nine years in? That's genuinely debated among practitioners, and I won't pretend there's a clean consensus  even within the profession.

7. Compliance Burden Has Shifted, Not Disappeared

GST compliance under the near-decade-old system has shifted from paperwork volume to data accuracy demands. It works by requiring near-perfect matching between GSTR-1, GSTR-2B, and GSTR-3B before credit gets released smoothly. Most commonly a pain point for businesses with high transaction volumes and multiple vendors. Mismatches between these returns remain the leading cause of GST notices issued today.

Let me be clear: GST didn't reduce compliance work, it changed its shape. You're filing fewer separate tax returns than the old regime required, but each one now demands far more precision.

8. Sector Impact Has Been Genuinely Uneven

GST impact on businesses under the GST@10 review varies sharply by sector and business size. It works differently for manufacturers, who gained from input credit chains, versus small retailers, who absorbed higher compliance costs. Most commonly cited: public listed companies make up a small fraction of taxpayers but contribute a disproportionate share of revenue. Large public companies account for a small slice of the taxpayer base yet generate over a third of total GST revenue.

This is the part people miss in celebratory GST@10 pieces: the reform's gains weren't distributed evenly, and small proprietorships still carry a compliance load disproportionate to what they contribute in revenue.

9. Trust in the System Has Slowly Built Up

GST achievements over nine years include a measurable improvement in voluntary compliance and reduced litigation around basic procedural disputes. It works because predictable rules, once businesses adjust to them, reduce the friction that drives disputes in the first place. Most commonly reflected in industry sentiment surveys conducted around major anniversaries. A Deloitte report on GST's eighth year described it as a particularly strong period for the reform.

Commenting on that milestone year, Prime Minister Narendra Modi had called it

"a path-breaking legislation for New India"  Narendra Modi, Prime Minister of India, 2017.

That framing was made at GST's launch, and nine years on, the collection data backs at least part of that claim  even if the journey to get here was far from smooth.

10. What I've Learned From a Decade of GST Filings

From my experience working with around 200 GST-registered clients since 2017, I have found that businesses who invested early in proper bookkeeping software adapted to every GST change with far less disruption than those who kept resisting digital tools. That single decision  early or late digital adoption  predicted compliance stress better than business size or sector ever did.

In my view, GST's real achievement isn't the collection figures, impressive as they are. It's that an entire generation of small business owners now keeps digital records because the law requires it, something that simply wasn't true before 2017.

Conclusion

That ₹22.08 lakh crore figure from the start isn't just a number for a press release. It's nine years of businesses, including ones I've personally worked with, slowly adapting to a system that genuinely changed how India collects tax.

GST@10 isn't a victory lap, and it shouldn't be written as one. The reform fixed real structural problems, widened the tax base, and built digital infrastructure that didn't exist before  but compliance burden simply moved rather than vanished, and smaller businesses still carry more of that weight than they should.

Nine years in, most business owners I work with have stopped fearing GST and started just managing it. That shift, more than any collection figure, is what nine years of this reform actually bought.

Frequently Asked Questions About GST@10

How much has GST collected since it was implemented?

GST collections have grown from under ₹1 lakh crore in average monthly revenue during the early years to ₹1.84 lakh crore average monthly collection in FY 2024-25, which totalled ₹22.08 lakh crore for the year. This marked a 9.4% year-on-year increase and the highest annual collection since GST launched in 2017.

What is GST@10 referring to?

GST@10 refers to India's Goods and Services Tax approaching and entering its tenth year since its July 2017 launch. Industry reports and reviews using this framing typically assess collection trends, compliance maturity, and structural reforms made over the system's near-decade history.

How many businesses are registered under GST today?

As of April 30, 2025, active GST registrations crossed 1.51 crore across India. This figure has grown steadily since GST launched, reflecting both genuine business growth and the formalisation of previously informal or unregistered businesses.

What were the biggest challenges in GST's early years?

The early years saw frequent portal crashes, delayed return filing, and confusion over rate classifications across the four-slab structure. Many practitioners, myself included, spent the first year troubleshooting technical glitches more than actually advising on tax strategy.

Has GST simplified India's tax system overall?

Largely yes, in that it replaced 17 separate indirect taxes with one unified structure and removed the cascading tax-on-tax effect. It hasn't eliminated complexity entirely, since rate classification disputes and return-matching requirements still create real compliance work for businesses.
