In India, the Goods and Services Tax (GST) is a comprehensive, multi-stage, destination-based tax levied on every value addition. If you are a business owner whose turnover exceeds the prescribed threshold limit, GST registration becomes mandatory. However, many applicants end up making avoidable mistakes during registration, which can lead to delays or even rejection.
In this guide, we will walk you through how to apply for GST registration online without errors, along with the key documents required, common mistakes to avoid, and some expert tips for a smooth process.
What is GST Registration?
GST Registration is a process by which a taxpayer gets registered under the Goods and Services Tax (GST) Act. Once registered, a unique 15-digit GST Identification Number (GSTIN) is assigned to the business. This number is essential for collecting GST, claiming input tax credits, and filing GST returns.
As per the GST law, it is mandatory for the following businesses to register:
Annual turnover exceeds ₹40 lakhs (₹10 lakhs for NE and hill states)
Inter-state supply of goods or services
E-commerce sellers
Casual taxable persons
Non-resident taxable persons
Who Needs to Register for GST?
GST registration is compulsory for:
Individuals making inter-state supply
E-commerce operators and sellers
Businesses exceeding turnover threshold
Agents of suppliers
Input service distributors
Reverse charge mechanism dealers
Non-resident taxable individuals
Casual taxable persons
Voluntary registration is also allowed, even if the turnover is below the limit.
