GST Registration Process – How to Apply Online

Starting a business in India comes with responsibilities, one of the most important being GST registration. It’s not just a legal requirement for eligible businesses but also a gateway to smooth operations and tax benefits. Whether you're a small trader, online seller, or a service provider, registering under GST helps you become tax-compliant and opens the door to benefits like input tax credit and better market reach.

What is GST Registration?

GST registration is a process where a business gets listed under the Goods and Services Tax system in India. It involves getting a unique 15-digit GSTIN (Goods and Services Tax Identification Number) issued by the GST department. This number is used for collecting and paying GST, filing returns, and maintaining tax compliance. Any business engaged in supplying goods or services, and meeting specific conditions, must register under GST. GST registration is also essential when applying for an MSME loan, as it helps establish the business’s credibility and compliance status.

GST registration is mandatory for businesses under the following categories:

1. Businesses with annual turnover above ₹40 lakh (₹20 lakh for services and ₹10 lakh in special category states).
2. Inter-state suppliers of goods and services.
3. E-commerce sellers or aggregators.
4. Casual taxable persons and non-resident taxable persons.
