In this detailed, updated 2025 guide, we will explain GST rules, eligibility, benefits, and exemptions to help you understand whether your business needs GST registration.

What Is GST Registration?

GST Registration is a legal process through which a business gets enrolled under the Goods and Services Tax Act. Once registered, a business receives a GSTIN (Goods and Services Tax Identification Number), which is required for filing GST returns, collecting taxes, and claiming input tax credit.

Is GST Registration Mandatory for Small Businesses?

The short answer is: Yes, GST registration becomes mandatory when a small business crosses the government-defined turnover limits or meets certain conditions.

Mandatory Turnover Threshold

As per the latest rules:

  • ₹40 Lakhs for goods (normal category states)
  • ₹20 Lakhs for services
  • ₹10 Lakhs for Northeastern & hill states

If your annual turnover crosses these limits, GST registration becomes compulsory.

When Small Businesses Must Register for GST (Even Without High Turnover)
