Introduction

Getting a GST registration (Goods and Services Tax Identification Number or GSTIN) is one of the most important steps for starting a business in India. Until a few years ago, the process was lengthy, often taking several days or even weeks due to manual verifications and document scrutiny. However, as of November 2025, the government has introduced GST 2.0, a new and simplified registration system that allows most genuine applicants to obtain their GSTIN within just 24 hours — and in some cases, up to three working days.

These reforms aim to make doing business in India faster, more transparent, and fully digital. This detailed guide will help you understand the entire process, step-by-step, along with the required documents, important tips, and ways to ensure same-day approval.

Step 1: Visit the Official GST Portal

The GST registration process begins on the official GST portal — www.gst.gov.in.

Once on the site, navigate to the ‘Services’ tab, select ‘Registration’, and click on ‘New Registration’.

You will be asked to provide the following details:

• PAN (Permanent Account Number) of the business or entity.
• Mobile number and email address of the primary authorized signatory.

After entering this information, an OTP (One Time Password) will be sent to both your mobile and email for verification. Once verified, you will receive a Temporary Reference Number (TRN), which will be used to log in and continue your GST registration.

Step 2: Complete the GST Application Form

After receiving the TRN, log in again using it and start filling out the GST REG-01 form. This form is divided into various sections, requiring details such as:

• Business details: Legal name, trade name, business constitution (proprietorship, partnership, company, etc.).
• Promoter/partner/director details: Information and ID proof of owners or key partners.
• Principal place of business: Full address and ownership proof such as rent agreement, electricity bill, or property papers.
• Bank account details: You can now choose to provide these later, once your GSTIN is generated.
• Goods and services information: Specify the nature of business and list your products or services using HSN (for goods) or SAC (for services) codes.

Take care to enter all information exactly as it appears in your PAN and business registration documents to avoid rejections or delays.

Step 3: Complete Aadhaar Authentication for Faster Approval

Once you have filled out your details, you will be asked to complete Aadhaar authentication. This is a crucial step introduced under GST 2.0 reforms that ensures faster and automated verification.

You can complete Aadhaar authentication in one of the following ways:

• OTP-based authentication: You receive a one-time password on your Aadhaar-linked mobile number and email.
• Biometric authentication: In some cases, physical biometric verification is required, but this is rare.

Applicants who complete Aadhaar verification successfully are treated as low-risk by the GST system and generally receive auto-approval within one day.

Step 4: Upload the Required Documents

For your GST registration to be processed without delay, ensure that you upload clear, valid, and consistent documents. The most commonly required documents include:

1. PAN card of the business or authorized signatory.
2. Aadhaar card for authentication.
3. Proof of business address – this could be a rent agreement, utility bill, or ownership document.
4. Certificate of incorporation or business registration proof such as partnership deed, LLP agreement, or registration certificate.
5. Photographs of promoters or business owners.
6. Bank proof – cancelled cheque or bank statement (can be submitted later if not available).

Before uploading, double-check that your document details match your PAN and business records exactly. Any mismatch may result in additional verification or rejection.

Step 5: Submit the Application and Track Status

After reviewing all the information, submit your application using an e-signature or a Digital Signature Certificate (DSC), depending on your business type.

Once submitted, you can track your application status anytime on the GST portal using your TRN or Application Reference Number (ARN).

If your application passes the system-based risk assessment and Aadhaar verification, your GSTIN will be automatically generated within 24 hours.

For applications requiring officer verification, approval usually takes no more than three working days, provided all documents are correct.

Common Reasons for Delay

Although most applications are processed quickly, there can be delays in the following situations:

• Mismatch between PAN and business name or details.
• Incorrect or unclear scanned documents.
• Application not verified through Aadhaar authentication.
• High-risk category flagged for additional scrutiny.
• Missing bank or address proofs.

Such cases are rare, but they can be avoided by ensuring accuracy in every step and opting for Aadhaar-based verification.

Key Highlights of GST 2.0 (Effective November 2025)

The GST 2.0 reforms introduced by the government in 2025 have simplified registration for new taxpayers. Some of the most notable updates include:

• Entirely online registration and verification process.
• Automatic GSTIN generation for low-risk, Aadhaar-verified applicants.
• Bank details can be submitted later, post-registration.
• Real-time document verification and minimal manual interference.
• Fast-track approval within 24–72 hours for most applicants.
• Simplified rules and enhanced transparency in the registration process.

These reforms make it possible for small and medium-sized enterprises to start operations legally without unnecessary administrative delays.
