GST Registration in India: Eligibility, Process & Timeline (2025 Guide)
There are a lot of legal requirements involved in starting a business in India, and GST registration is one of the most important. Understanding the GST process helps you avoid penalties and ensures your business remains compliant with Indian tax laws.
Many startups completing startup legal registration or executing a partnership deed often miss GST requirements in the early stages, which later leads to notices and fines.
What Is GST Registration?
GST registration means obtaining a unique 15-digit Goods and Services Tax Identification Number (GSTIN) issued by the government. This allows businesses to legally collect GST and claim input tax credit.
Introduced on July 1, 2017, GST replaced multiple indirect taxes under the “One Nation, One Tax” system, simplifying tax compliance for businesses operating across states.
Who Needs to Register for GST in India?
GST registration is mandatory for businesses falling under the following categories:
- Goods suppliers with annual turnover above ₹40 lakhs
- Service providers with turnover above ₹20 lakhs
- Lower limits apply to special category states
- Inter-state sellers and e-commerce operators
- Businesses liable under reverse charge mechanism
Even businesses dealing with contracts like vendor agreements or recurring services under a Master Service Agreement (MSA) often require GST regardless of turnover.
Documents Needed for GST Registration
- PAN and Aadhaar of business owner
- Business registration proof
- Bank account proof
- Address proof of business premises
- Authorization letter or board resolution
- Digital Signature (for companies/LLPs)
Incorrect documentation is one of the most common reasons GST applications get rejected.
