Only businesses operating in a particular state or territory are granted the 15-digit Goods and Services Tax identification number, or GSTIN. A taxpayer will receive a GSTIN to use on their tax returns and invoices following GST registration.

The business is assigned a unique GSTIN following the review and approval of the GST registration application by the GST officer. In order to confirm the authenticity of the seller and the GST number or GSTIN listed on the invoice, every business that is subject to GST must disclose the GSTIN.

Under the Goods and Services Tax, companies that make more than Rs. 40 lakhs, Rs. 20 lakhs, or Rs. 10 lakhs, as applicable, are required to register as regular taxable persons. According to CGST Section 10 of the Composition Plan, the threshold turnover limit for a select group of professionals and small enterprises is Rs. 50 lakh and Rs. 1.5 crore, respectively.

• Generate e-way bills.
• Update transportation details.
• Cancel or extend validity of e-way bills.

They ensure transparency in goods movement and help prevent tax leakage across state borders.

11. Transitional Credit Forms

• Declare closing balances of VAT, service tax, and excise.
• Claim credit in the GST regime.

Though transitional forms were primarily used during the initial phase of GST rollout, they remain important for audits and legacy cases.

12. Inspection Forms

To enforce compliance, the GST department has been empowered to conduct inspections, searches, and seizures. Inspection Forms are used to:

• Record inspection details.Notify taxpayers about searches or seizures.Maintain legal validity of actions taken during enforcement.

These forms are crucial for transparency and safeguarding taxpayer rights during enforcement actions.

• Standardised invoice generation.
• Real-time validation.
• Auto-population of returns.

This mechanism prevents fake invoicing and allows seamless integration between tax systems and ERP platforms.

Each of these GST form categories supports different business and administrative functions. Whether it’s a small business opting for composition, a non-resident registering temporarily, or an exporter filing for a refund, the relevant GST forms are central to fulfilling obligations and availing lawful benefits under the GST regime.

What is the Penalty for Not Getting A GST Registration?

Every business within India that surpasses the GST threshold (₹40 Lakh for goods, ₹20 Lakh in services, or ₹10 Lakh for certain special category states) must register for GST. Penalty for non-registration amounts to ₹10,000 or 10% of the tax dues, whichever may be higher.

However, in cases of intentional tax evasion, the penalty may be as high as 100% of tax dues. Besides being unable to claim input tax credit, non-registration would lead to business stagnation and the possibility of legal consequences.
