GST Registration Simplified | Auto Approval & ₹2.5 Lakh Threshold | CBIC Notification 18/2025 Explained

The Central Board of Indirect Taxes and Customs (CBIC) has notified the Central Goods and Services Tax (Fourth Amendment) Rules, 2025, through Notification No. 18/2025 – Central Tax, dated 31^st October 2025 introducing important amendments to the GST registration process.

The amendments aim to simplify registration for genuine taxpayers, streamline processing, and reduce fraudulent registrations through data-driven and risk-based verification.

Key Amendments Introduced

Insertion of Rule 9A – Grant of Registration Electronically

A new Rule 9A has been introduced to provide automatic electronic registration through the common portal.

Highlights of Rule 9A:

• Applicable to applicants under Rule 8, Rule 12, or Rule 17 of the CGST Rules.
• Registration will be granted electronically within three working days of application submission.
• The system will use data analytics and risk parameters to identify eligible applicants for automatic registration.

Impact:
This will reduce manual intervention, quicken the process for low-risk applicants, and make GST registration smoother for compliant businesses.

Insertion of Rule 14A – New Option for Small Taxpayers

Rule 14A introduces a new optional registration category for taxpayers whose monthly output tax liability towards registered taxpayers does not exceed ₹2.5 lakh (i.e., ₹30 lakh annually approximately).

Key Provisions of Rule 14A:

• Available to persons applying for registration under Rule 8.
• Not applicable to persons notified under Section 25(6D) of the CGST Act.
• Aadhaar authentication is mandatory for eligibility.
• Registration granted electronically within three working days after Aadhaar verification.
• Restriction: A person cannot obtain another registration under the same PAN in the same State/UT under this rule.

 Withdrawal Option under Rule 14A

A new FORM GST REG-32 is introduced for taxpayers who wish to withdraw from the option availed under Rule 14A.

 Conditions for Withdrawal:

• Can be filed only after furnishing:
  • Returns for minimum 3 months (if before 1 April 2026), or
  • 1 tax period (if on or after 1 April 2026).
• All pending returns must be filed before applying for withdrawal.
• No proceedings under Section 29 (cancellation) should be pending.
• Application verified under Rule 9 and processed through FORM GST REG-33 (approval) or FORM GST REG-05 (rejection).

Updated and New GST Forms Introduced

Practical Example

Suppose a small business applies for GST registration with output tax liability of ₹2 lakh per month towards registered Taxpayer.

They can now choose Rule 14A registration, complete Aadhaar authentication, and get registration within 3 working days — without physical verification.

If later their liability exceeds ₹2.5 lakh per month, they must withdraw from Rule 14A using FORM GST REG-32, after filing at least 3 months’ returns.

 Objective Behind These Changes

The CBIC’s intent is clear —

-Encourage voluntary registration for small taxpayers,

-Ensure faster processing for low-risk applicants, and

-Use data analytics to curb fake registrations.

This dual approach of ease + enforcement aligns with the government’s broader goal of “Trust but Verify” in GST compliance.

 Effective Date

All these provisions come into force from 1st November 2025.

Tax professionals and businesses applying for new registration on or after this date should review the new Rules 9A and 14A carefully while filing their applications.
