For small businesses, understanding and complying with GST regulations is crucial for legal operation, availing input tax credits, and expanding their market reach. While the process might seem daunting initially, the online GST registration portal has made it significantly more accessible.

This comprehensive guide, tailored for small businesses in India as of May 19, 2025, will walk you through the step-by-step online process of obtaining GST registration. We’ll break down the eligibility criteria, the documents you need, and the detailed procedure on the GST portal, empowering you to navigate this essential compliance requirement with clarity and ease.

Is GST Registration Mandatory for Your Small Business? Understanding the Thresholds

Before diving into the process, it’s crucial to determine if your small business is liable for GST registration. As of 2025, the threshold limits for GST registration in India are primarily based on your aggregate turnover in a financial year:

• General Category States: ₹40 lakh for businesses dealing exclusively in goods and ₹20 lakh for businesses dealing in services or a mix of goods and services.
• Special Category States (e.g., North-Eastern states, Himachal Pradesh, Uttarakhand): ₹20 lakh for businesses dealing exclusively in goods and ₹10 lakh for businesses dealing in services or a mix of goods and services.

However, even if your turnover is below the threshold, GST registration might be mandatory in certain scenarios, including:

• Making Inter-State Supplies: If your business supplies goods or services to customers in other states.
• E-commerce Operators or Suppliers through E-commerce Operators: If you sell goods or services through online platforms.
• Reverse Charge Mechanism: If you are liable to pay tax under the reverse charge mechanism.
• Input Service Distributor (ISD).
• Casual Taxable Person or Non-Resident Taxable Person.

It’s essential to assess your business activities and turnover to determine your GST registration liability.
