the 8-step online process, required documents,
GSTIN format, benefits, and penalties.

Basics

What is GST Registration?

Understanding India's unified tax system and why registration is your first step.

GST (Goods and Services Tax)

is a single, unified indirect tax levied on the supply of goods and services across India. It replaced a complex web of old taxes and created a seamless "one nation, one tax" system.

GST Registration in India

gives your business a unique 15-digit GSTIN number — your legal tax identity. Without it, you cannot legally collect GST from customers or claim Input Tax Credit (ITC).

Old taxes replaced by GST:

Eligibility

You are legally required to register under GST if any of the
following apply to your business.

Goods Sellers

If your annual turnover from selling goods exceeds the threshold limit, GST Registration is mandatory.

Service Providers

Professionals, consultants, freelancers, and agencies providing services must register once they cross the limit.

Inter-State Sellers

Selling goods or services across state borders? GST Registration is compulsory regardless of turnover amount.

E-Commerce Sellers

Selling on Amazon, Flipkart, Meesho, or any e-commerce marketplace requires mandatory GST Registration.

Step-by-Step

How to Complete GST
Registration Online

The complete 8-step process on gst.gov.in — with real examples from
Ravi's Textile business in Hyderabad.

Step 1 — Visit the GST Portal

Go to www.gst.gov.in. Click on "Services" → "Registration" → "New Registration" to begin the
GST Registration process.

💡 Example: Ravi's textile shop in Hyderabad opens the portal to begin registration

Step 2 — Fill Part-A (Basic Information)

Select your taxpayer type (Regular / Composition). Enter your PAN, email address, and mobile number. Verify both using OTP received on each.

💡 Example: Ravi enters PAN: ABCPR1234D, email & mobile → verifies both OTPs

Step 3 — Receive TRN (Temporary Reference Number)

After Part-A verification, you receive a 15-digit TRN via email and SMS. This is valid for 15 days — use it to complete Part-B.

💡 Example: Ravi's TRN: 36221118514042T — valid for 15 days

Step 4 — Fill Part-B (Business Details)

Login with TRN. Fill in business name, address, nature of business, HSN/SAC codes for your products/services, and your bank account details.

💡 Example: Ravi fills "Ravi Textiles", Hyderabad address, selects "Retail Trade"

Step 5 — Upload Required Documents

Upload your PAN, Aadhaar, address proof (electricity bill or rent agreement), bank proof (cancelled cheque), proprietor photograph, and partnership deed if applicable.

💡 Example: Ravi uploads electricity bill + cancelled cheque

Step 6 — Verify and Submit Application

Sign using DSC (Digital Signature Certificate) for companies/LLPs, or EVC (OTP via Aadhaar-linked mobile) for individuals and proprietors.

💡 Example: Ravi uses EVC — OTP sent to his Aadhaar-linked mobile

Step 7 — Receive ARN (Application Reference Number)

Post submission, you receive an ARN to track your application status on the portal under "Track Application Status." Status shows "Pending with Tax Officer."

💡 Example: Ravi's ARN: AA361018514042R — checks status after 3 days

Step 8 — Receive Your GSTIN Certificate

Within 7 working days, a GST officer verifies your application. You receive your 15-digit GSTIN — your official tax identity number for doing business across India.

💡 Example: Ravi's GSTIN: 36ABCPR1234D1Z5 (36 = Telangana state code)
