Once registered, the business receives a Goods and Services Tax Identification Number (GSTIN) that allows it to legally collect GST from customers and claim Input Tax Credit (ITC) on purchases.

Under the GST law, businesses crossing certain turnover limits or engaged in specific activities are required to obtain GST registration.

What is GST Registration?

GST registration is the formal process through which a business becomes recognized as a registered taxpayer under the GST law.

After successful registration, the government issues a 15-digit GST Identification Number (GSTIN) which serves as the unique identity of the taxpayer under GST.

With GST registration, a business can:

• Collect GST on taxable supplies
• Claim input tax credit on purchases
• Issue GST-compliant tax invoices
• File GST returns with the government

Without GST registration, businesses are not permitted to collect GST from customers.

GST Registration Turnover Limit in India

GST registration becomes mandatory when the annual turnover of a business exceeds certain limits.

If a business crosses the applicable turnover limit during a financial year, it must apply for GST registration within 30 days.

Businesses That Must Register Under GST (Even Without Turnover Limit)

Certain businesses are required to obtain GST registration regardless of their turnover.

These include:

• Businesses making interstate supply of goods
• E-commerce sellers
• Non-resident taxable persons

• Input Service Distributors (ISD)
• Businesses required to deduct TDS under GST
• Businesses required to collect TCS under GST
• Online Information Database Access and Retrieval (OIDAR) service providers
• Agents supplying goods or services on behalf of other taxable persons
