GST registration in India: who needs it, documents and process

GST registration is compulsory in India once your turnover crosses the prescribed limit, and in some cases even before it. Here is who needs it, what to keep ready and how the process works.

Who needs to register for GST?

You must register if your aggregate turnover in a financial year goes above the threshold for your kind of business. The limit is different for suppliers of goods and suppliers of services, and lower limits apply in special category states. The government can change these limits, so always confirm the current figure on the official GST portal.

Some businesses must register whatever their turnover. Common examples are:

• Businesses that supply goods from one state to another
• Sellers who sell through e-commerce platforms
• Non-resident and casual taxable persons
• Businesses that must pay tax under reverse charge
• Businesses that deduct or collect tax at source

Can I register for GST voluntarily?

Yes. A business below the threshold can still register. Many do it to claim input tax credit on their purchases, to sell to larger buyers who ask for a GSTIN, or to sell across states. Once registered you must follow all GST rules and file returns, even when you had no sales in a period.

What documents are needed for GST registration?

The exact list depends on how your business is set up. For most applicants it includes:

• PAN of the business or the owner
• Aadhaar of the owner, partners or directors
• Proof of the business address, such as a rent agreement with a recent utility bill, or an ownership document
• Bank account proof, such as a cancelled cheque or a statement
• A recent photograph of the owner, partners or directors
• For firms and companies: the incorporation or partnership documents and an authorisation letter for the person signing

How does the GST registration process work?

1. You fill in the application on the GST portal with your business details and upload the documents.
2. You verify it with an OTP or a digital signature, and you receive an application reference number (ARN).
3. The tax officer checks the application. The officer may ask for clarification or more documents.
4. Once approved, you receive your 15-digit GSTIN and a registration certificate.

How long the officer takes depends on the department and on how complete your documents are, so we do not promise a fixed number of days.

What happens after you get your GSTIN?

You display the GSTIN at your place of business, issue tax invoices and file your returns on time. Most regular taxpayers file GSTR-1 for sales and GSTR-3B for the tax summary. Read our guide to GST return filing before your first due date.

Common mistakes to avoid

• Using an address that does not match the proof you upload
• Choosing the wrong constitution of business (for example, proprietorship instead of partnership)
• Leaving out a place of business or the goods and services you deal in
• Ignoring a query from the officer, which can lead to rejection
