GST registration is mandatory in certain situations, even if a business has low turnover. The GST law clearly defines specific cases where registration cannot be avoided.
GST registration is compulsory in the following cases:
-
Turnover exceeds the threshold limit
Businesses must register if aggregate turnover exceeds ₹40 lakh for goods (₹20 lakh for services) in most states. For special category states, the limit is lower. -
Inter-state supply of goods or services
Any business supplying goods or services across state borders must register under GST, regardless of turnover. -
E-commerce operators and sellers
Businesses selling through e-commerce platforms or operating an e-commerce portal are required to register. -
Casual taxable persons
Individuals or businesses supplying goods or services occasionally in a taxable territory where they do not have a fixed place of business must register. -
Non-resident taxable persons
Foreign entities supplying goods or services in India are required to register under GST. -
Persons liable under reverse charge mechanism (RCM)
If a business is required to pay GST under RCM, registration becomes compulsory. -
Input Service Distributors (ISD)
Entities distributing input tax credit to branches must be registered. -
Agents supplying on behalf of others
Agents making taxable supplies on behalf of a principal must obtain GST registration. -
TDS/TCS deductors under GST
Persons required to deduct or collect tax at source under GST must register.
From a compliance perspective, businesses need to closely track turnover, nature of supply, and transaction types to determine registration requirements. Many businesses use cloud accounting software to monitor these thresholds and maintain GST-ready records.
For example, platforms like Giddh help businesses maintain accurate accounting data and GST-compliant invoices, making it easier to identify when GST registration becomes mandatory and to stay compliant once registered.
In short, GST registration is compulsory not only based on turnover but also on the nature and scope of business activities, and understanding these conditions is essential to avoid penalties.
