This blog post explains why checking GST numbers before every transaction is essential and how this one small habit safeguards your money and strengthens your business foundation.

Why is a GSTIN required?

The Goods and Services Tax Identification Number is essentially the virtual identity card for any business in India that has been registered under GST. You require this special 15-digit code to establish that your business is on the government record and eligible under the tax laws.

  • This number is a way for the tax department to monitor your sales and make sure taxes get deposited properly in the government treasury.
  • You require this specific registration number to issue valid tax invoices and to pass on credit benefits to buyers.
  • The law says you must have this number if you want to sell goods or services to customers in other states.
  • Online marketplaces like Amazon or Flipkart will only allow you to sell on their platforms if you provide this number.
  • Having a valid number builds confidence in your clients because it shows you are a serious and compliant business player.

Why is it necessary to verify the GST number?

Checking the GST details of your vendors is a financial safety measure that you simply cannot afford to ignore today. You risk losing your own money if you pay tax to a supplier who has a cancelled or fake registration.

  • Protection against fake invoices and fraud: You verify that the bill comes from a real company that actually exists in the government database and not on paper. Scammers often use fake numbers to collect taxes from you, which they never deposit, leaving you in legal trouble.
  • Securing your Input Tax Credit eligibility: You can only claim tax credit if your supplier files their returns and pays the tax to the government on time. Checking their status helps you avoid lazy or non-compliant vendors who will cause your tax credit claims to get rejected.
  • Preventing legal notices and penalties: Trading with unregistered or fake dealers attracts immediate attention from tax officers and leads to unnecessary legal questions for you. You protect your reputation by ensuring that every single person in your supply chain is a verified and honest taxpayer.

  • Enter the code as it is shown in the image: Type the security characters shown on the screen correctly and hit the search button to pull up the business details.
  • Analyse the displayed company’s details: Look through their legal name, jurisdiction, and filing table to make sure that they are active and compliant.

What are the uses of the GSTIN search and verification tool?

This tool serves as a health check report for your vendor, helping you decide whether they are safe to do business with.

  • Checking the business is still active: You can check at any time whether the supplier’s registration has been suspended or cancelled by the tax office because of non-compliance.
  • Confirmation of legal name and constitution: It confirms that the business name on the invoice matches precisely with what’s recorded in government incorporation or registration records.
  • Checking the return filing history: Refer to the filing table if the supplier really files GSTR-1 and GSTR-3B on a monthly basis.
  • Verifying the business address registered: The application shows you the location of their head office, which enables you to check whether they do indeed work from there.
  • Identifying the type of tax registration: You can find out if the vendor is a regular taxpayer or a composition dealer, which changes how they bill you.

How can GSTIN be misused?

Fraudsters are always looking for loopholes, and your business could become a victim if you do not pay close attention. 

  • Issuing fake invoices to make credit transfer: Criminals simply steal real GST numbers, issue false bills, and sell no goods. They then sell the illegal tax credits.
  • Identity theft on behalf of legitimate businesses: Fraudsters may operate using your business information to engage in unlawful transactions unbeknownst to you, leaving you responsible with the tax authorities.
  • Taxing without depositing: Unregistered suppliers sometimes affix a random number to their bills to tax you, and that remains only in their possession.
  • Creating shell companies for money laundering: Some use these numbers to set up fake companies that exist only to turn black money into white money.
