The Goods and Services Tax (GST) is a unified tax system in India that mandates businesses to register based on turnover and other specific criteria. While voluntary registration is an option for small businesses, compulsory registration is required for certain entities, irrespective of turnover. This ensures tax compliance, transparency, and seamless input tax credit (ITC) flow.

Businesses engaged in inter-state supplies, e-commerce operations, and certain notified services must register under GST without considering their annual revenue. Non-compliance with compulsory registration can lead to hefty penalties, legal consequences, and disruption of business operations.

Specific categories of persons need to register under GST mandatorily, irrespective of the threshold limit, as per Section 24 of the Act, for the supply of services and goods, as follows:

  • Dealers involved in taxable interstate supply (registered person).
  • Casual taxable persons dealing with taxable services and goods.
  • Individuals paying tax under the reverse charge mechanism.
  • E-commerce operators (Electronic commerce operators)

General Threshold Limits

The threshold limits for GST registration are as follows:

  • Goods Suppliers: If you are a supplier of goods with an annual turnover exceeding ₹40 lakh, you must register under GST.
  • Service Suppliers: If you are a service supplier with an aggregate annual turnover of ₹20 lakh, you need to register under GST as per the GST Council's regulations.

Special Category States 

The threshold limit for GST registration differs for unique category states such as Arunachal Pradesh, Jammu & Kashmir, Assam, Manipur, Mizoram, Meghalaya, Nagaland, Tripura, Sikkim, Himachal Pradesh and Uttarakhand. Businesses in these states need to register under GST if their annual business turnover for goods supply is ₹20 lakh and for service supply is ₹10 lakh.

Mandatory GST Registration Criteria for Inter-state Supplies

Businesses dealing with inter-state supplies need to mandatorily register under GST as per Section 24(i) of the GST Act. However, here are the exceptions to the rule:

FAQs

Who is required to register for GST in India?

Businesses that cross the prescribed turnover limits—₹40 lakh for goods and ₹20 lakh for services—must register for GST. Additionally, individuals involved in inter-state supplies, e-commerce, reverse charge mechanism, and other specific categories listed under Section 24 of the CGST Act must register regardless of turnover. Voluntary registration is also permitted for smaller businesses to avail input tax credit benefits.

Are there different GST registration limits for certain states?

Yes, the threshold limits are lower for special category states like Assam, Manipur, Mizoram, Tripura, and others. In these states, GST registration is mandatory for goods suppliers with turnover exceeding ₹20 lakh and for service providers with turnover above ₹10 lakh. These adjusted thresholds account for the economic and geographic considerations of such regions.

Is GST registration mandatory for inter-state service providers?

Not always. Inter-state service providers are exempt from mandatory GST registration if their annual turnover is below ₹20 lakh (₹10 lakh in special category states). However, this exemption does not apply to inter-state goods suppliers, who must register regardless of turnover under Section 24(i) of the CGST Act.

What is the GST rule for non-resident taxable persons (NRTP)?

Non-resident individuals or businesses supplying goods or services in India must mandatorily register under GST, regardless of turnover.

A non-resident taxable person must also appoint an authorized representative and pay tax in advance based on estimated liability.

What are the consequences of not registering under GST when required?

Failure to register under GST when mandatory can result in penalties, interest, and legal action. The penalty includes a fixed amount or a percentage of the tax due, whichever is higher. Non-compliance can also disrupt business operations, disqualify entities from claiming input tax credits, and damage the business’s credibility.
