Are you doing business? Know, when GST registration is required?

The GST Act provides that every supplier of goods or services or both who has an aggregate turnover of more than Rs. 20 lakhs in a year (Rs.10 lakhs in Special Category States) have to obtain GST registration.

However if the supplier is supplying goods only, then threshold limit will be Rs. 40 lakhs in a year (Rs.20 lakhs in Special Category States) subject to the condition that State has opted for this higher threshold limit.

However, there are certain categories of suppliers who are required to obtain mandatory registration irrespective of their turnover limit.

Who Should Register for GST?

Mandatory GST Registration basis on Turnover -

Every supplier exclusively engaged in supply of goods with turnover above the threshold limit of Rs. 40 Lakhs* (Rs. 20 Lakhs for North-Eastern States, J&K, Himachal Pradesh and Uttarakhand)

Every supplier making a taxable supply of goods or services or both with turnover above the threshold limit of Rs. 20 Lakhs* (Rs. 10 Lakhs for North-Eastern States, J&K, Himachal Pradesh and Uttarakhand)

Mandatory GST Registration irrespective of Turnover -

Any persons making any inter-State taxable supply [Section 24]

Casual taxable persons making taxable supply [Section 24]

Persons who make taxable supply of goods or services or both on behalf of other taxable persons whether as an agent or otherwise.

Those paying tax under the reverse charge mechanism

Person who supplies via e-commerce seller /aggregator, however e-commerce sellers / aggregators need not required registration if total sales is less than Rs. 20 lakh. Notification No. 65/2017 – Central Tax dated 15.11.2017 [Section 24]

When a business which is registered has been transferred to someone/demerged, the transferee shall take registration with effect from the date of transfer.

However, aggregate Turnover shall not include value of any inward supply on which tax is liable to be paid by a person on reverse charge basis. Turnover shall also not include GST paid on any supply.
