Online GST registration process: Step-by-step guide

A casual taxable person is an individual who conducts business or supply of goods or services occasionally but does not have a fixed place of operation. An ISD is an entity that receives tax invoices for the supply of goods or services.

An individual who is a part of the supply of goods or services in India but is not a resident of the country must also register their business for a GST number to comply with the tax laws of the country. 

A business that supplies goods or services outside its state of operations is known as an interstate supplier. If this type of business has multiple branches in different states, then they must register each branch for a unique GST number. 



Any business selling and supplying goods or services through an e-commerce portal must also register for a GST number.

If you are a business that deducts TDS (tax deducted at source) on payments or you are a business that collects tax at source (TCS - tax collected at source) then you must obtain a GST number. 

Any business selling digital services or products online through information technology is also liable to pay taxes and register for GST.

Businesses that do not earn revenue as per the turnover criteria need not register for GST. Although they can voluntarily complete the online GST registration process if they want to. 



There are many people who are involved in the business of supplying goods and services that are exempt under the GST tax law. These include

• Unprocessed food items like salt, eggs, milk, rice, vegetables, wheat, meat, fish, bread, cereals, etc

• Education

• Healthcare but not medicines

• Train travel by local and sleeper classes

• Hotels that have a rent of less than INR 1000

Certain items such as alcohol for human consumption, electricity, natural gas, petroleum & crude petrol, high-speed diesel, and aviation fuel are non-taxable goods and services. 

There are certain businesses or professional activities that do not fall under the supply of goods and services and are hence exempt from GST. These activities include

• The services of a court or Tribunal 

• Services provided by an employee to the employer

• Funeral services

• The sale of land/building

• The functions and duties of government authorities, an individual having a constitutional position, and a person who is a Chairperson/Member/Director of a body. 

If a person is involved in the supply of goods or services that are charged with tax only under the reverse mechanism, then they need not register for GST. 



People who are involved in supplying products cultivated on land are also exempt from GST registration. Other agricultural input services such as irrigation, fertilizers, and machinery are also exempted from GST tax laws.

A normal taxpayer is any business that falls under the regular tax laws of the country and is not a part of any other scheme or composition. This is most businesses within the country that fall under the turnover criteria to mandatorily register for GST.



A casual taxable person is part of a business that is seasonal or occasional in nature. So this type of business must only pay taxes equal to the seasonal operations of the business.

Such businesses are generally provided a tenure of 3 months for GST registration but they can also apply to extend this period or renew it. 



Under the composition scheme, a business pays a fixed amount of GST regardless of what its turnover is.

This scheme can only be opted for by businesses that have annual revenue of up to INR. 10,000,000 in India. Companies choose this scheme when they see that it is monetarily beneficial for them. 

People and businesses that do not live in India but are involved in the supply of goods or services to people who reside within India are also liable to pay taxes as a non-resident conducting business.

The tenure issued to a non-resident taxable person for GST is 3 months. This can also be renewed or extended if needed. 

Getting your business GST registration done under the GST tax laws in India greatly benefits in legitimizing your business entity.

Having a GST number helps you be legally recognized by authorities and other businesses to validate and prove you’re a real business. 

Before GST was introduced in India, the lax laws in the country were pretty confusing. Many states had their own tax structure making it tough for businesses to operate and manage all financial and accounting tasks for the same.

With GST, the entire country follows one tax structure making it easier for accountants to manage financial operations.



The major benefit that businesses get under the GST tax structure is that they don’t have to face the cascading effects of compounding taxes as a product moves through the supply chain. This also benefits consumers to get cheaper products.
