Introduction

GST registration is one of the most important compliance requirements for businesses operating in India. While GST registration is mandatory in certain situations irrespective of turnover, many businesses become liable for registration only after crossing the prescribed turnover threshold.

The GST threshold limits differ based on:

• Nature of supply (Goods or Services)
• Category of State (Normal State or Special Category State)
• Type of business activity

Understanding the applicable threshold limit is essential to avoid penalties for delayed registration and ensure smooth GST compliance.

This article explains the GST registration threshold limits applicable for FY 2026-27 and the situations where registration is compulsory regardless of turnover.

What is GST Registration?

GST Registration is the process through which a taxpayer obtains a GST Identification Number (GSTIN) and becomes legally authorized to collect GST from customers and claim Input Tax Credit (ITC).

Once registered, the taxpayer is required to:

• File GST returns
• Maintain prescribed records
• Pay GST on taxable supplies
• Comply with GST provisions
