Applying for a GST (Goods and Services Tax) number is an essential step for businesses and professionals in India who want to operate legally and claim tax benefits. The GST system simplifies indirect taxation and ensures transparency across the supply chain. One of the key requirements for GST registration is a valid PAN (Permanent Account Number), which acts as the primary identity for tax purposes.
In this guide, you’ll learn how to apply for a GST number using your PAN card in a clear, structured, and practical way. Whether you’re a small business owner, freelancer, or startup founder, this step-by-step article will help you complete the process smoothly.
Why is a PAN Card Mandatory for GST Registration
The PAN card serves as the backbone of GST registration. The government uses it to link your financial and tax-related data across systems. Without a PAN, you cannot generate a GSTIN (Goods and Services Tax Identification Number).
Here’s why PAN is crucial:
- It verifies your identity as a taxpayer
- It helps track your tax liabilities and filings
- It prevents duplication and fraud in registrations
- It connects your GST account with income tax records
For businesses like partnerships, LLPs, or companies, the PAN of the entity (not the individual) is required.
Who Needs to Apply for a GST Number
Not everyone needs GST registration, but certain categories must apply mandatorily. You should register for GST if:
- Your turnover exceeds ₹40 lakh (₹20 lakh for services in most states)
- You are involved in the interstate supply of goods or services
- You run an e-commerce business
- You are a freelancer providing taxable services
- You want to claim input tax credit
Voluntary registration is also allowed, even if your turnover is below the threshold, which can enhance business credibility.
Documents Required for GST Registration
Before starting your application, make sure you have the following documents ready:
- PAN card of the applicant or business
- Aadhaar card
- Proof of business address (electricity bill, rent agreement, etc.)
- Bank account details (cancelled cheque or bank statement)
- Photograph of the applicant
- Digital Signature Certificate (for companies and LLPs)
Having these documents prepared in advance will speed up the process significantly.

Step 2: Fill Part A of the Application
Enter the following details:
- Legal name (as per PAN)
- PAN number
- Mobile number
- Email address
- State/UT
After submitting, you will receive OTPs on your mobile and email for verification.
Step 3: Generate Temporary Reference Number (TRN)

Step 5: Aadhaar Authentication

Step 6: Application Submission
After reviewing all details, submit the application using:
- Digital Signature Certificate (DSC), or
- Electronic Verification Code (EVC)
You will receive an Application Reference Number (ARN) to track your status.
GST Application Approval Process
After submission, the GST officer reviews your application. There are three possible outcomes:
- Approval: You receive your GSTIN and registration certificate
- Clarification Required: You must provide additional information
- Rejection: If documents or details are incorrect
Typically, approval takes 3–7 working days if all information is accurate.
Common Mistakes to Avoid During GST Registration
Many applicants face delays due to simple errors. Avoid these common mistakes:
- Entering incorrect PAN details
- Mismatch between PAN and Aadhaar information
- Uploading unclear or invalid documents

Accuracy is key—double-check everything before submission.

- Easier expansion across states
For growing businesses, GST registration is not just a compliance requirement—it’s a strategic advantage.

This unique number identifies your business under GST.
