GST Registration in India 2024: Complete Step-by-Step Guide

What is GST Registration?

GST (Goods and Services Tax) registration is the process of enrolling your business under India's unified indirect tax system. Once registered, your business receives a unique 15-digit GSTIN (Goods and Services Tax Identification Number) that must appear on every tax invoice you raise.

GST replaced over 17 central and state taxes — including VAT, service tax, and excise duty — when it was introduced on 1 July 2017. Today, it is the backbone of India's indirect tax framework.

Who Must Register for GST?

GST registration is mandatory if your business falls under any of the following categories:

Annual aggregate turnover exceeds ₹20 lakh (₹10 lakh for special category states like Himachal Pradesh, Uttarakhand, and North-Eastern states)
You make inter-state taxable supplies regardless of turnover
You are an e-commerce operator or sell through an e-commerce platform
You are a casual taxable person or non-resident taxable person
You are required to pay tax under the reverse charge mechanism
You are an Input Service Distributor (ISD)

Pro Tip: Even if your turnover is below ₹20 lakh, voluntary GST registration is beneficial if you supply to GST-registered businesses — it allows you to pass on Input Tax Credit (ITC) and makes your business more competitive.

Documents Required for GST Registration

Keep the following documents ready before you begin:

PAN card of the business / proprietor / partners / directors
Aadhaar card (linked to mobile number for OTP verification)
Proof of business registration (Certificate of Incorporation, Partnership Deed, etc.)
Proof of principal place of business (electricity bill, rent agreement, or NOC from owner)
Bank account statement / cancelled cheque
Authorised signatory details + digital photograph
DSC (Digital Signature Certificate) for companies and LLPs

Step-by-Step GST Registration Process

Part A — Generate TRN: Visit the GST portal (gst.gov.in), enter PAN, mobile number and email. Verify OTPs to get a Temporary Reference Number (TRN).
Part B — Fill Application: Log in with TRN and fill the REG-01 form — business details, principal place of business, nature of business, bank details.
Upload Documents: Upload all supporting documents in the prescribed formats (JPEG/PDF, max 1 MB each).
Verification: The application is verified using your Aadhaar OTP, DSC, or EVC.
ARN Generated: An Application Reference Number (ARN) is issued. Track status on the portal.
GSTIN Issued: Upon approval, your GSTIN is issued via email — usually within 3 working days for Aadhaar-authenticated applications.

GST Registration Fees

There is no government fee for GST registration. However, professional charges from a CA or compliance firm typically range from ₹999 to ₹2,499 depending on the complexity and support level you need.

Display GSTIN on your business premises and all tax invoices

If you fail to register when required, you may face a penalty of ₹10,000 or the amount of tax evaded, whichever is higher, along with interest at 18% per annum on the tax due.
