The GST Registration process in India is now entirely online through the official portal — www.gst.gov.in. Designed to simplify tax compliance, this digital process allows businesses to register, verify, and receive a GSTIN (Goods and Services Tax Identification Number) without visiting any office.

Under GST law, any business whose annual turnover exceeds ₹20 lakh (₹40 lakh for goods or ₹10 lakh for specific states) must register for GST. Voluntary registration is also allowed for smaller businesses seeking input tax credits or interstate supply permissions.

Latest GST Registration Updates (2024–2025)

🔹 April 17, 2025 — New CBIC Instructions

The CBIC issued new instructions to streamline GST registration and prevent unnecessary document requests. Key clarifications include:

• Accepted proofs for principal place of business and business constitution are now standardized.

• Officers cannot request redundant documents like the lessor’s PAN or Aadhaar.

• All registration applications must be approved within prescribed timelines to reduce delays.

🔹 February 12, 2025 — Aadhaar & Biometric Authentication Advisory

The GSTN introduced a three-tier classification for applicants:

1. Without Aadhaar authentication.

2. With Aadhaar authentication plus biometric verification.

3. Cases where ARN (Application Reference Number) is not generated.
   Applicants must comply based on their category.

🔹 July 10, 2024 — Biometric Verification Extended Nationwide

Biometric-based Aadhaar authentication — earlier limited to Gujarat and Puducherry — now applies across India.
Applicants who skip Aadhaar authentication must personally verify documents at designated facilitation centers.

Who Needs to Register for GST?

GST registration is mandatory for:

• Businesses exceeding the turnover threshold.

• Interstate suppliers of goods or services.

• E-commerce operators and aggregators.

• Casual taxable persons (e.g., seasonal businesses, exhibitions).

• Non-resident taxable persons.

• Input service distributors (ISD).

• Anyone liable to pay tax under reverse charge.

Voluntary registration is beneficial if you wish to claim input tax credit (ITC) or supply interstate.

Documents Required for GST Registration

Before you begin, keep these documents ready:

Step-by-Step Process to Register for GST Online

Here’s the complete GST registration guide 2025, explained clearly:

Step 1: Visit the GST Portal

Go to www.gst.gov.in → Services → Registration → New Registration.

Select:

• “I am a” → Taxpayer

• Choose your State and District

• Enter Legal Name of Business and PAN

• Provide Email ID and Mobile Number (linked to PAN, if available)

Click Proceed to receive OTPs for verification.

Step 2: Generate Temporary Reference Number (TRN)

After OTP verification, you’ll get a 15-digit TRN (sent to your registered email and mobile).
This TRN is valid for 15 days and allows you to continue your registration later if incomplete.

Step 3: Log in Using TRN

Revisit the portal → New Registration → Temporary Reference Number (TRN) → Enter TRN and Captcha → Proceed.
Verify OTP again to access your saved application draft.

Step 4: Fill Part-B of the Application

Part B consists of 10 sections:

1. Business Details

2. Promoter/Partner Information

3. Authorized Signatory

4. Principal Place of Business

5. Additional Places of Business

6. Goods and Services (HSN/SAC codes)

7. Bank Account Details

8. State-Specific Information

9. Aadhaar Authentication

10. Verification

Each section turns blue once completed.

Step 5: Business Information

Enter:

• Trade Name (if different from legal name)

• Business Constitution (Proprietorship, LLP, Company, etc.)

• Date of commencement and GST liability start date

• Option to opt into Composition Scheme (for small businesses under ₹1.5 crore turnover)

If you are an SEZ unit, ISD, or casual taxable person, enter relevant details and upload supporting documents.

Step 6: Promoter/Partner Details

Add details for up to 10 promoters or partners, including:

• Name, PAN, Aadhaar, address, contact details, and photo

• Director Identification Number (if applicable)

• Citizenship status

Mark if the promoter is also the primary authorized signatory.

Step 7: Authorized Signatory

Enter similar details as above.
Authorized signatories can file returns and sign applications on behalf of the business.

Step 8: Principal Place of Business

Provide:

• Full address, contact number, and ownership type (owned/rented/shared)

• Upload proof — property tax receipt, rent deed, or NOC from owner

• Select business activity type: manufacturer, wholesaler, trader, etc.

You can also add additional places of business.

Step 9: Goods/Services Details

Enter up to 5 HSN codes for goods and 5 SAC codes for services that your business deals in.
These codes determine your applicable GST rate.

Step 10: Aadhaar Authentication

Choose Yes for Aadhaar authentication to avoid physical verification delays.
Complete OTP or biometric verification as required.
Applicants skipping Aadhaar must verify in person at facilitation centers.

Step 11: Verification and Submission

Tick the declaration and submit the form using one of the following:

• DSC (Digital Signature) – mandatory for companies/LLPs

• E-sign – OTP to Aadhaar-linked number

• EVC – OTP to registered mobile

After submission, you’ll receive an Application Reference Number (ARN) via email/SMS.

Step 12: ARN Tracking and Approval

Use the ARN to track your registration status on the portal:
Services → Registration → Track Application Status → ARN.

If all validations and verifications are successful, your GSTIN (15-digit GST number) will be issued and sent via email/SMS.

Key Things to Remember

• Turnover Limits: ₹40L (goods), ₹20L (services), ₹10L (special states)

• Aadhaar Authentication: Greatly speeds up approval

• Bank Details: Optional at registration, mandatory later

• Timelines: Applications must be processed within 7 working days (or 30 if verification needed)

• No Fees: GST registration is free of cost on the government portal

Why GST Registration Matters

• Legal recognition of your business

• Eligibility for Input Tax Credit (ITC)

• Ability to make interstate supplies

• Trust and credibility with customers and vendors

• Compliance with tax law to avoid penalties

Conclusion

The 2025 GST registration process is faster, clearer, and more secure — thanks to Aadhaar-based authentication and streamlined documentation.
If your business crosses the threshold or deals in interstate supplies, registering under GST is not only mandatory but also beneficial for long-term compliance and credibility.
