When GST was rolled out on 1st July 2017, the idea was straightforward: replace a cluttered web of excise duties, VAT and service taxes with one unified system. And by and large, it worked. GST did bring uniformity to India’s tax structure. But as with any large system, once people figured out how it worked, some figured out how to work around it. Today, GST frauds in India have become one of the biggest challenges to the country’s indirect tax system, with increasingly sophisticated methods used to evade taxes and claim fraudulent Input Tax Credit (ITC).
GST frauds in India has not decreased over the years. If anything, it has grown more organised and harder to trace. The government has responded with stronger tools, but taxpayers, businesses and professionals still need to understand what these frauds look like, who is at risk, and what the consequences are.
According to GST Council data and CBIC enforcement reports, GST evasion detected in FY 2024-25 crossed Rs. 2.01 lakh crore, with fake invoice networks and bogus ITC claims continuing to dominate the fraud landscape. The government has now made e-invoicing mandatory for businesses with an annual turnover above Rs. 5 crore, significantly narrowing the window for paper-based manipulation.
What Is GST Fraud?
GST fraud refers to deliberate malpractices aimed at reducing or avoiding tax liability. Any individual, business, or legal entity can be involved. The impact is not limited to the government’s revenue — it distorts competition, harms compliant businesses and puts the broader economy under strain.
The Four Main Types of GST Frauds in India
1. Input Tax Credit (ITC) Fraud and Fake GST Invoices
Input Tax Credit is one of the most useful — and most abused — features of the GST framework. The idea behind ITC is sound: businesses should not pay tax on tax. If you have already paid GST on your inputs, you should be able to set that off against your output liability.
The problem is fake GST invoices. Two parties collude to raise invoices for goods or services that were never actually supplied. Fake bank entries are created to make the transactions look real. The receiving party then claims ITC on these fictitious purchases, reducing its tax outgo — while the government receives nothing.
The CBIC’s dedicated Fake ITC Detection Drive has been running since 2023. In FY 2024-25, over 10,700 fake GSTIN registrations were identified and cancelled, and more than Rs. 36,000 crore in bogus ITC was blocked. Fraudsters have now shifted to using shell companies with valid Aadhaar-linked registrations to evade detection. The Department is increasingly using AI-based risk scoring on GSTN data to flag suspicious ITC claim patterns before refunds are processed.
2. Circular Trading
Circular trading involves two or more businesses in a chain — each one issuing invoices to the next, with fake payment entries to match. The final entity in the chain raises an invoice that loops back, completing the circle. The net result: substantial ITC is claimed on transactions where nothing real has moved.
What has changed is the sophistication. Circular trading networks in 2025-26 often span multiple states and use multiple GSTINs, making it harder for a single GST authority to see the whole picture. The GST Council has responded by strengthening data-sharing protocols between state GST administrations and the Centre, and by mandating real-time reconciliation of ITC claims against supplier GSTR-1 filings through the GSTN portal.
3. Export Fraud and False GST Refund Claims
The Indian government provides genuine incentives for exporters — including GST refunds on exported goods. Export fraud exploits these benefits by claiming refunds on shipments that never actually left the country, or by misrepresenting what was exported.
The methods include fake shipping bills, forged post-shipment documents, bribing port officials for stamp clearances, and misquoting HSN codes to make non-eligible goods appear eligible for refunds.
Customs and GST authorities have deepened integration since 2023, with ICEGATE (the customs portal) and the GSTN now cross-verifying shipping bills in near real-time. The Ministry of Finance introduced additional verification steps in 2024 for refund claims above Rs. 50 lakh, including mandatory physical verification for first-time refund applicants in high-risk categories. Despite this, export refund fraud remains one of the top three GST frauds categories by value.
4. GST Misclassification
GST rates in India vary widely — from 0% on essential goods to 28% on luxury items. Misclassification means deliberately putting a product or service in a lower tax bracket than it belongs to. A business selling a luxury product but classifying it under an essentials category, for instance, pays far less GST than it should.
Misclassification has become more common in newer categories — particularly in digital services, branded packaged foods, and online gaming (following the 28% GST levy on the latter in 2023). The AAR (Authority for Advance Rulings) has seen a spike in classification-related applications, and CBIC has issued several clarificatory circulars to close interpretational gaps that fraudsters exploited.
Why Does GST Frauds Keep Growing?
The motivations behind GST frauds have not changed much since 2017. They include:
- Generating fake invoices to pass on ITC to third parties and earn a commission on the transfer
- Inflating turnover to improve creditworthiness and access higher overdraft or cash credit limits from banks
- Boosting company valuations before an IPO or a stake sale
- Qualifying for government or private manufacturing contracts that require a minimum turnover threshold
- Reducing taxable profit by showing inflated expenses
An emerging motivation is the misuse of the composition scheme and the QRMP (Quarterly Return Monthly Payment) scheme — both intended to ease compliance for small businesses — to suppress actual turnover and avoid the audit and scrutiny thresholds that apply at higher revenue levels.
GST Frauds Penalties and Prosecution Thresholds
Offences That Attract Penalty Under Section 122
Under Section 122 of the CGST Act, the following acts are treated as punishable offences:
- Issuing invoices without actual supply of goods or services
- Failing to issue an invoice for a genuine supply
- Fraudulently claiming tax refunds
- Claiming ITC without actual receipt of goods or services
- Manipulating financial records or books of accounts
- Not obtaining GST registration when required
- Providing false information to tax officers
- Suppressing, destroying or tampering with evidence or seized goods
The base penalty is Rs. 10,000 or an amount equal to the tax evaded — whichever is higher.
Prosecution and Jail Terms
- Tax evaded between Rs. 1 crore and Rs. 2 crore: Up to 1 year imprisonment, plus penalty
- Tax evaded between Rs. 2 crore and Rs. 5 crore: Up to 3 years imprisonment, plus penalty
- Tax evaded above Rs. 5 crore: Up to 5 years imprisonment, plus penalty
The Finance Act 2024 brought in amendments that make compounding of offences stricter for repeat offenders. The GST Council has also discussed — though not yet legislated — increasing the prosecution threshold ceiling for habitual offenders, particularly those involved in organised fake invoice networks operating across multiple states.
Government Measures: What Has Actually Changed Since 2023
The two biggest structural changes that the GST regime introduced to combat fraud are e-invoicing and e-way bills — both of which the original 2023 article covered. Here is where things stand in 2026:
E-Invoicing: Now mandatory for all businesses with annual turnover above Rs. 5 crore. Every B2B invoice must be generated through the Invoice Registration Portal (IRP), which issues a unique IRN (Invoice Reference Number) and a QR code. This makes it virtually impossible to create a fake invoice that cannot be cross-verified by the recipient or the tax authority.
E-Way Bills: Required for movement of goods above Rs. 50,000 in value. Integration of e-way bill data with FASTAG and GPS on highways now allows real-time tracking of goods movement, making it harder to claim a shipment occurred when it did not.
AI-Based Risk Profiling: The GSTN has deployed machine-learning models to flag suspicious taxpayer behaviour — sudden spikes in ITC claims, mismatches between GSTR-1 and GSTR-3B, and new registrations in high-fraud sectors. Taxpayers who are flagged are placed under enhanced scrutiny before their ITC is released.
Biometric Aadhaar Authentication: Since 2024, GST registration in high-risk states and sectors requires biometric Aadhaar verification at a GST Seva Kendra, rather than OTP-based authentication. This directly targets the problem of fraudsters registering shell companies using stolen Aadhaar details.
ITC Suspension for Mismatch: Amendments to Rule 86A now allow GST officers to block the use of ITC in the electronic credit ledger where fraud or misuse is suspected, without waiting for the completion of adjudication proceedings.
A Final Word
Not every GST error is a fraud. Systems are imperfect, classifications are sometimes genuinely ambiguous, and honest mistakes do happen. Every person accused of a GST offence has the right to be heard and to submit documentary evidence in their defence. Unintentional errors, once proved, are treated differently from deliberate evasion.
That said, the line between an honest mistake and wilful evasion is one that tax authorities are now better equipped to identify than they were in 2017. With e-invoicing, biometric registration, AI risk-scoring and tighter inter-agency coordination, the window for manipulation has narrowed considerably.
For businesses, the practical takeaway is simple: get your classifications right, reconcile your ITC claims every return period, and make sure your suppliers are filing their returns. In 2026, your ITC is only as safe as your vendor’s compliance record.
