1. What is GST Registration?

GST registration is the process through which a business or individual becomes a registered taxpayer under the Goods and Services Tax Act. After registration, a unique GSTIN (Goods and Services Tax Identification Number) is issued, which must be used for all GST-related transactions, filings, and invoices.

Registration under GST is mandatory if your business crosses the prescribed turnover limit or falls under the compulsory registration category.

2. Who Needs to Apply for GST Registration?

Here are the categories of persons and businesses required to register under GST:

• Businesses with turnover exceeding ₹40 lakh (₹20 lakh for services in most states)

• Inter-state suppliers of goods or services

• E-commerce sellers and aggregators

• Casual taxable persons

• Non-resident taxable persons

• Input Service Distributors (ISDs)

• Agents of a supplier

• Businesses registered under previous tax laws (VAT, Excise, Service Tax)

Even if your turnover is below the threshold, you can voluntarily register for GST to avail input tax credit and improve credibility.

3. Benefits of GST Registration

Registering for GST brings several advantages:

• Legitimacy for your business in the eyes of clients and suppliers

• Input Tax Credit (ITC) on business purchases

• Participation in inter-state trade

• Legal recognition as a supplier of goods or services

Voluntary registration also helps startups and small businesses who want to expand across states or sell through online platforms.

For Proprietorship:
