A Fake GST Number is an invalid or counterfeit GSTIN used to evade taxes, generate fraudulent invoices, and manipulate input tax credits (ITC). These deceptive numbers pose financial risks to businesses, mislead customers, and cause significant revenue loss for the government.

How Fake GST numbers are created?

Some fraudster keep an intent to create bogus GST numbers by manipulating or fabricating GSTINs. They do all this in order to hoodwink the authorities and avoid taxes. These numbers appear legitimate but are not registered in the GST system. Below are few common and identified (by GST officials) ways to create:

#1 – Modifying a Genuine GST Number

They create a fake one by modifying an existing GSTIN by changing one or more digits. As the GST numbers follow a particular 15-digit pattern, slight changes make them look authentic initially.

#2 – Using Expired, Revoked, or Cancelled GSTINs

Some businesses have their GST registration cancelled for not complying or even due to voluntary closure, yet they use old GSTINs to issue invoices. Miscreants also misuse such numbers to avoid tax liability.

#3 – Generating Random GSTINs in the Correct Format

A GSTIN follows a pattern and fraudsters generate random numbers of the same pattern but never register with the GST database. They then use them on invoices to create fictitious ITC claims or to avoid paying tax.

#4 – Creating Shell Companies with Fake GST Registration

Fraudsters get a GSTIN and create imaginary businesses with fake documents, such as PAN cards, Aadhaar cards, and business addresses; they generate bogus invoices using these shell companies and manipulate tax credits.

#5 – Using Stolen GSTINs from Other Businesses

Others steal the actual GST numbers of registered businesses and issue their names in respect of fake invoices. The business may not even know that their GSTIN is being misused until they receive a notice from tax authorities.

#6 Fake GST Numbers for E-commerce or Online Scams

Sometimes, fraudulent sellers in e-commerce websites provide fake GST numbers to customers and charge GST from them, not remitting it to the government.

Reasons for Using Fake GST Numbers

Fraudsters and most unethical business officials use fake GST numbers for several financial frauds, with the main intention being to evade taxes, manipulate transactions, and commit financial fraud. Some of the most prominent reasons why such fake GST numbers are generated and misused are as follows:

  1. Tax Evasion – Frauds use false GST numbers to avoid paying taxes, which adds to their ill-gotten margins. By not paying taxes, they run a business without following all the due processes, which is a setback for the government revenue.
  2. Fraudulent ITC Claims using fake invoices: To falsely reduce the tax liabilities, thereby showing revenue leakage in the government revenue account and to show unfair advantage in competition.
  3. Black Money conversion using fake GST number by issue of fake invoice for converting the black money to legitimate transactions with money laundering as well as other financial fraud.
  4. Running Unregistered Businesses – some firms rely on fake GST numbers to give themselves the appearance of legitimacy but operate unregistered. Therefore, they escape tax liability at the same time as cheating customers and suppliers.
  5. GST Audits and Regulatory Scrutiny Evasion – Fraudsters issue fake GSTINs to prevent government scrutiny. This allows them to carry out illicit business and remain in a ‘hands-clean’ state, not filing their returns or getting caught for evasion.
  6. Selling goods or service without paying GST  – The businesses making use of the fake GST numbers collect GST from their customers but never pay to the government the amount collected as GST. This will involve some types of financial fraud and the consumers will be uncompromisingly involved in tax evasions.
  7. Hiding business identity and doing illegal trade – The criminal makes his way by using a forged GST number for his unlawful activities, like smuggling, selling pirated goods, and avoiding import/export duties, which is very difficult for the authorities to track fraudulent transactions.

Common Signs of a Fake GST Number

  1. Incorrect Format or Structure
  2. Untraceable on the GST Portal
  3. Mismatch Between Business Details and GSTIN
  4. No GST Return Filings
  5. Invoices Lacking GST Compliance
  6. Businesses Hesitant to Provide GSTIN
  7. Use of Canceled or Expired GST Numbers

Note: To ensure compliance and prevent fraud, businesses should always verify GST numbers before engaging in financial transactions and report any suspicious cases to the tax authorities.

#1: Using the Official GST Portal
The best way to verify is to visit official GST portal and check the GST number under “Search Taxpayer” section. Make sure you put GST number in the search box and hit “Search.”

A valid GSTIN has a specific format:

  • The first two characters describe the state code.
  • The following ten characters describe the PAN of the business.
  • The 13th digit is based on the number of registrations done under the same PAN.
  • The 14th digit is always ‘Z’.
  • The 15th digit is a checksum character used for validation.

If any part of this structure is incorrect, the GST number is likely fake.

#3: Verifying GSTIN Through Third-Party Tools
There are various third-party GST verification software and mobile applications that enable speedy verification of GST numbers. The tools access data in the GST database to check on business names, the status of registration, and return filing. They, however, should be cross-checked with the official GST portal.

#4: Confirming Business Details with Invoices and PAN Records
If a business provides a GST number, then the name and PAN details should match on their official invoices. Mismatched details indicate possible fraud, and further verification is needed.

#5: Cross-Checking GST Returns and Compliance
The registered businesses need to file their GST returns regularly. Checking the return filing history of a GSTIN can indicate whether the business is active and compliant. A business with no return filings or irregular submissions may be using a fake or inactive GST number.

#6: Contacting GST Helpline or Tax Authorities
If there’s still a doubt regarding the authenticity of any GST number, an individual can raise a query to the GST helpdesk or local tax authority for verification. The GST helpline at 1800-103-4786 can also be contacted to authenticate the GSTIN.
