Goods and Services Tax (GST) has transformed India’s indirect tax system by unifying multiple taxes into a single framework. Since its introduction, GST registration has become mandatory for many businesses, traders, professionals, and startups. Thanks to digitization, online GST registration in India is now a simple, transparent, and fully online process.
This comprehensive guide explains everything you need to know about online GST registration—eligibility, benefits, documents required, step-by-step process, fees, timelines, and common mistakes to avoid.

What Is GST Registration?
GST registration is the process through which a business gets registered under the Goods and Services Tax Act. Once registered, the business receives a GST Identification Number (GSTIN), a unique 15-digit number that allows it to:
- Collect GST from customers
- Claim input tax credit
- File GST returns
- Conduct business legally across India
Any business registered under GST must comply with GST laws and regulations.
