Pro Tip: Ensure all key individuals (Proprietor, Karta, Managing Director, Partners, or Authorised Signatory) have their Aadhaar details updated and readily accessible. This proactive step can significantly expedite your GST registration process and prevent delays.

What are the key takeaways from the Delhi High Court ruling on GST registration?

• Delhi High Court affirms mandatory biometric Aadhaar authentication for GST registration.
• The underlying statutory notification framework identifies the authorised signatory of all types, managing and authorised partners of a partnership firm, and the Karta of an HUF for Aadhaar authentication; the September 2026 Court direction is broader because it requires biometric Aadhaar authentication before fresh GST registration is allowed, for the time being.
• Under the existing Rule 9 framework, failure to undergo Aadhaar authentication or not opting for it can place the application in the physical-verification route; the September 2026 Court direction separately requires biometric Aadhaar authentication before a fresh registration is allowed, subject to the Court proceedings and implementation.
• Registration timeline extends from seven working days to thirty days for non-authenticated applicants.
• Under Rule 8(4A), as substituted by Notification No. 04/2023-Central Tax, applicants who opt for Aadhaar authentication and are identified by the portal based on data analysis and risk parameters are required to undergo biometric-based Aadhaar authentication, photograph capture and original-document verification at a notified Facilitation Centre. The September 2026 interim Court direction has temporarily broadened the practical requirement to fresh GST registrations generally.

What did the Delhi High Court rule regarding biometric Aadhaar authentication for GST registration?

The Delhi High Court, by an interim order dated 8 September 2026, directed authorities across the country, for the time being, not to allow any fresh GST registration without biometric-based Aadhaar authentication. The September 2026 Court direction is broader in practical effect: for the time being, authorities across India have been directed not to allow a fresh GST registration without biometric-based Aadhaar authentication. This is an interim judicial direction; it should not be described as a permanent amendment listing every person named in section 25(6C).

Section 25(6A) to (6D) of the CGST Act, 2017 creates the statutory framework for Aadhaar authentication, while the Government specifies the persons and classes to whom the requirement applies by notification. For registration, Notification No. 18/2020-Central Tax covers individual applicants and Notification No. 19/2020-Central Tax covers specified persons in non-individual entities. This means it cannot be claimed as a matter of right by ordinary registration applicants. This interpretation aligns with the proviso to Rule 9(1) of the CGST Rules, 2017, which mandates physical verification of the place of business when a person fails to undergo Aadhaar authentication or does not opt for such authentication, thereby extending the registration approval timeline from seven working days to thirty days.

How does the biometric Aadhaar authentication process operate under the CGST Rules?

The biometric authentication process functions through a structured mechanism under Rule 8(4A) of the CGST Rules, 2017, as substituted by Notification No. 04/2023-Central Tax dated 31st March, 2023. When an applicant opts for Aadhaar authentication and is identified on the common portal based on data analysis and risk parameters, the application must be followed by biometric-based Aadhaar authentication and photograph capture. This requires the applicant—or the relevant individuals in case of non-individual entities—to visit one of the Facilitation Centres notified by the Commissioner for this purpose.

The application is deemed complete only after completion of this process. For applicants who successfully undergo authentication, the date of submission of the application is treated as the date of the completion of such biometric-based Aadhaar authentication and taking of photograph or the date of furnishing of the information and documents referred to in sub-rule (2), whichever is later, as per Rule 8(4A) of the CGST Rules, 2017. Failure to complete this process within the stipulated timeframe means the application is not considered submitted, and no Application Reference Number (ARN) is generated. This mechanism ensures that high-risk applicants cannot bypass the biometric verification requirement, thereby strengthening the registration framework against fraudulent entities.

What happens if an applicant fails to complete Aadhaar authentication within the fifteen-day window?

Under Rule 8(4A) of the CGST Rules, 2017, as substituted by Notification No. 04/2023-Central Tax dated 31st March, 2023, an applicant who opts for Aadhaar authentication must complete the process within fifteen days from the submission of Part B of FORM GST REG-01. If authentication is not completed within this period, the application is not deemed complete, and no Application Reference Number (ARN) is generated. If the applicant does not complete the required authentication within the applicable period, the application is not treated as complete under the rule and the applicant may have to restart the registration process. The exact portal workflow can depend on the application status and the applicable exemption or verification route.

The consequences are significant. Under the proviso to Rule 9(1), a person who fails to undergo Aadhaar authentication as specified in sub-rule (4A) of Rule 8, or who does not opt for authentication, faces mandatory physical verification of the place of business. The registration approval timeline extends from seven working days to thirty days from the date of submission of the application. Furthermore, under Rule 9(5) of the CGST Rules, 2017, as substituted by Notification No. 94/2020-Central Tax, if the proper officer fails to take action within the prescribed period, the application is deemed to have been approved—but this deemed approval mechanism applies only after the thirty-day window has elapsed in non-authenticated cases.

How do the registration timelines differ based on authentication status?

Practical impact: A worked example of timeline and cost implications

Consider a partnership firm in Delhi applying for GST registration on 1st October, 2026. If the partner completes biometric authentication at a Facilitation Centre within the fifteen-day window under Rule 8(4A) of the CGST Rules, 2017, the proper officer must approve registration within seven working days under Rule 9(1). The firm receives its GSTIN by approximately 12th October, 2026, and can begin issuing tax invoices immediately.

Now consider the same firm opting out of Aadhaar authentication entirely. Under the proviso to Rule 9(1), as amended by Notification No. 94/2020-Central Tax, the registration can only be granted after physical verification of the place of business, with a timeline of thirty days. The firm receives its GSTIN only by approximately 31st October, 2026—a delay of roughly nineteen working days. During this period, the firm cannot collect GST from customers, cannot claim input tax credit, and may face contractual penalties for delayed invoicing. For a firm with an estimated monthly taxable supply of ₹25,00,000 at 18% GST, this delay means a deferred GST collection of ₹4,50,000 and a corresponding working capital blockage for nearly one month.

This example illustrates why the Delhi High Court’s affirmation of mandatory biometric authentication, while seemingly restrictive, actually benefits compliant taxpayers by enabling faster registration. The real cost falls on applicants who cannot or will not authenticate—they face the extended thirty-day timeline and mandatory physical verification under Rule 25, as read with the proviso to Rule 9(1) of the CGST Rules, 2017.

Illustrative example only; actual figures, terms and outcomes vary.

What documents and steps are required for biometric Aadhaar authentication at Facilitation Centres?

The biometric verification process at Facilitation Centres operates under the proviso to Rule 8(4A) of the CGST Rules, 2017, as substituted by Notification No. 04/2023-Central Tax dated 31st March, 2023. When an applicant opts for Aadhaar authentication and is identified on the common portal based on data analysis and risk parameters, the following steps must be completed at a Facilitation Centre notified by the Commissioner.

First, the applicant must carry the original copies of all documents uploaded with the application in FORM GST REG-01. This includes proof of principal place of business, identity proof, address proof, and photographs as specified under Rule 8 of the CGST Rules, 2017. Second, the individual(s) required by the applicable GST registration workflow—such as the proprietor/applicant or the notified person for a non-individual entity—must be physically present for biometric-based Aadhaar authentication and photograph capture. Third, the Facilitation Centre operator verifies the original documents against the uploaded copies and records the biometric data through the UIDAI-linked device.

The application is deemed complete only after this entire process is finished. If any one of the required individuals—whether the Primary Authorised Signatory or the selected Promoter or Partner—fails to visit the Facilitation Centre, or if biometric authentication fails, or if document verification remains incomplete within the fifteen-day window, the application is not deemed complete under Rule 8(4A). The portal workflow may therefore require the applicant to complete the prescribed process again before the registration application can proceed.

Who is exempt from mandatory Aadhaar authentication for GST registration?

This provision states that the requirements of sub-section (6A), sub-section (6B), or sub-section (6C) shall not apply to such person or class of persons, or any State or Union territory or part thereof, as the Government may specify by notification on the recommendations of the Council. The Government has exercised this power to exempt specific categories, and the exemption cannot be claimed by ordinary registration applicants as a matter of right.

Exempted categories include those who are not citizens of India, as well as departments or establishments of the Central Government or State Governments, local authorities, statutory bodies, Public Sector Undertakings, and persons applying for a Unique Identity Number (UIN). For registered persons who have already been issued a certificate of registration and who fall outside the Aadhaar authentication requirement, Rule 10B of the CGST Rules, 2017—inserted by Notification No. 35/2021-Central Tax dated 24th September, 2021—provides an alternative mechanism. If an Aadhaar number has not been assigned to the person required to undergo authentication, such person may furnish identification documents including the Aadhaar Enrolment ID slip along with a bank passbook with photograph, voter identity card issued by the Election Commission of India, passport, or driving license issued by the Licensing Authority under the Motor Vehicles Act, 1988.

However, this alternative documentation is a temporary facility. The proviso to Rule 10B mandates that such person must undergo Aadhaar authentication within thirty days of the allotment of the Aadhaar number. The statutory exemption framework under section 25(6D) of the CGST Act, 2017 is distinct from the alternative documentation facility under Rule 10B. The former applies at the registration application stage for specific classes of persons, while the latter applies to existing registered persons for specific purposes such as filing revocation applications, refund applications, or claiming refunds of integrated tax on exported goods.

What are the consequences of GST registration suspension under Rule 21A(2A) for non-compliance?

Rule 21A(2A) of the CGST Rules, 2017, empowers the proper officer to suspend registration when a registered person fails to furnish details of a valid bank account under Rule 10A within the prescribed time period. However, the suspension mechanism intersects with Aadhaar authentication in a critical way: where registration was granted based on physical verification due to non-completion of Aadhaar authentication, and subsequent data analysis reveals discrepancies, the officer may suspend registration with immediate effect under Rule 21A(2A), citing grave threat to revenue interest.

The 52nd GST Council meeting recommendations, as documented in the Council agenda, proposed strengthening this mechanism by providing for system-based suspension of registration in respect of registered persons who do not furnish valid bank account details within the time prescribed under Rule 10A. The Council further recommended automatic revocation of suspension upon compliance. This creates a dual compliance burden: applicants must not only complete Aadhaar authentication but also ensure timely bank account linkage to avoid suspension cascades that disrupt business operations and input tax credit flows.

How do Aadhaar authentication requirements differ across business constitutions?

Section 25 of the CGST Act, 2017, together with the applicable notifications and the proviso to Rule 8(4A) as substituted by Notification No. 04/2023-Central Tax. The table below maps these requirements across common business structures.

What practical steps should applicants take to avoid registration delays?

Based on our experience handling GST registration matters, we recommend the following approach to minimise processing timelines and avoid the thirty-day physical verification route under the proviso to Rule 9(1) of the CGST Rules, 2017.

First, applicants should opt for Aadhaar authentication as “Yes” during FORM GST REG-01 submission. This triggers the OTP-based authentication pathway for low-risk applicants, enabling completion within seven working days under Rule 9(1). For high-risk applicants flagged by the common portal based on data analysis and risk parameters, biometric verification at a Facilitation Centre becomes mandatory under the proviso to Rule 8(4A), as inserted by Notification No. 04/2023-Central Tax.

Second, applicants must complete the authentication process within the fifteen-day window from submission of Part B of FORM GST REG-01. Failure to do so means no ARN is generated, and the application is not considered submitted. The link expires after fifteen days, requiring a fresh application. For applicants who cannot complete authentication due to Aadhaar not being assigned, the alternate identification documents specified under Rule 10B—Aadhaar Enrolment ID slip along with bank passbook with photograph, voter identity card, passport, or driving licence—must be furnished, with Aadhaar authentication completed within thirty days of Aadhaar allotment.

Second worked example: Cost of delay for a manufacturing MSME

Consider a private limited manufacturing company in Gujarat applying for GST registration on 15th September, 2026. The MD is identified as high-risk based on data analysis, triggering mandatory biometric authentication at a Facilitation Centre under the proviso to Rule 8(4A) of the CGST Rules, 2017. The MD visits the centre on 18th September, 2026, and authentication is completed. The proper officer approves registration within seven working days under Rule 9(1), and the GSTIN is issued by 26th September, 2026.

Now consider the same company opting out of Aadhaar authentication. Under the proviso to Rule 9(1), as amended by Notification No. 94/2020-Central Tax, physical verification of the place of business is mandatory. The registration is granted only after thirty days, approximately by 15th October, 2026. The company has pending purchase orders worth Rs 15 lakh from 1st October, 2026, which it cannot execute without a GSTIN. The estimated loss of revenue during the twenty-day delay is Rs 15 lakh, plus additional costs of Rs 18,000 in GST that would have been charged to customers and remitted after claiming input tax credit on raw material purchases of Rs 10 lakh. The total financial impact of opting out of Aadhaar authentication exceeds Rs 15 lakh in this scenario—a disproportionate cost compared to the inconvenience of visiting a Facilitation Centre.

What are the practical implications for businesses applying for GST registration?

The Delhi High Court’s September 2026 interim direction reinforces a significant change in how fresh GST registrations are practically processed. It operates alongside section 25 of the CGST Act, 2017 and the existing Rule 8 and Rule 9 framework. The practical impact extends beyond timeline delays. Firms that fail to authenticate face not only the thirty-day processing window under Rule 9(1) proviso but also the operational disruption of mandatory physical verification under Rule 25, which requires the applicant’s presence at the place of business.

For non-individual entities, the complexity depends on the notified persons and the current portal workflow. Section 25(6C) allows the Government to specify persons for Aadhaar authentication, and Notification No. 19/2020-Central Tax identifies the authorised signatory of all types, managing and authorised partners of a partnership firm, and the Karta of an HUF. A private limited company, for instance, must ensure that either the Managing Director or a whole-time Director completes biometric authentication. If the designated individual is unavailable or fails to authenticate within the fifteen-day window under Rule 8(4A), the application stalls entirely, and no ARN is generated. This creates a single point of failure that can delay business commencement by weeks.

Section 25(6D) of the CGST Act, 2017 provides the exemption power, but only for persons or classes specifically notified by the Government. Ordinary registration applicants cannot claim this exemption. Furthermore, Rule 10B of the CGST Rules, 2017, as inserted by Notification No. 35/2021-Central Tax, extends Aadhaar authentication requirements to existing registered persons for specific purposes—revocation of cancellation, refund applications, and refund of integrated tax on exports. This means the authentication requirement is not a one-time hurdle at registration but an ongoing compliance obligation.

What Should You Do Next?

• Verify that the mobile number and email ID linked with Aadhaar on the UIDAI portal are active and accessible before initiating the GST registration application.
• Submit Part B of FORM GST REG-01 promptly and book the Facilitation Centre appointment immediately upon receiving the biometric authentication link, ensuring completion within the fifteen-day window under Rule 8(4A) of the CGST Rules, 2017.
• Carry original copies of all documents uploaded with the application to the Facilitation Centre, as verification of originals is mandatory under the proviso to Rule 8(4A) as substituted by Notification No. 04/2023-Central Tax.
• Monitor the common portal for ARN generation—if no ARN is generated within fifteen days, the authentication process has failed, and the application must be resubmitted.
• Furnish bank account details within the timeline prescribed under Rule 10A of the CGST Rules, 2017, to avoid system-based suspension of registration under Rule 21A(2A).
• Maintain records of authentication completion and Facilitation Centre visit acknowledgements, as these may be required if the proper officer initiates physical verification under Rule 25 of the CGST Rules, 2017.

What is Central Tax (CT) in the context of GST?

Central Tax (CT) refers to the tax levied by the Central Government on intra-state supplies of goods and services under the Goods and Services Tax (GST) regime. It is one of the two components of GST charged on intra-state transactions, the other being State Tax (ST) or Union Territory Tax (UTT).

CT applies to all taxable persons making intra-state supplies. Registered persons are responsible for collecting Central Tax from their customers and remitting it to the Central Government.

What is a Primary Authorised Signatory (PAS) in GST?

A Primary Authorised Signatory (PAS) in GST is the individual officially designated by a business entity to perform all necessary functions on the GST portal and represent the business in all GST-related matters. This includes filing GST registration applications, submitting periodic and annual returns, responding to communications and notices, and engaging in dispute resolution.

Every business entity, such as a company, partnership firm, or Hindu Undivided Family (HUF), must appoint a Primary Authorised Signatory. This individual holds the legal authority and responsibility to act on behalf of the business. For Aadhaar authentication purposes, the Primary Authorised Signatory, or other designated individuals depending on the business constitution, must undergo the biometric verification process.

What is the Principal Place of Business (PP) under GST?

The Principal Place of Business (PP) under GST refers to the main location within a state or Union Territory where a taxpayer conducts their business activities. This address is crucial for GST registration and compliance purposes, as it serves as the central hub for the business.

At the Principal Place of Business, the business typically maintains its primary books of accounts and records, and it is often where the head office or top management is situated. Physical verification of the business premises, as mandated in certain GST registration scenarios (e.g., when Aadhaar authentication is not opted for), is conducted at this declared location.

What is the role of the Law Committee in GST?

The Law Committee is a crucial committee operating under the Goods and Services Tax (GST) Council. It comprises officers from both the Central Government and State Governments. Its primary role is to examine legal and procedural issues related to GST and provide recommendations to the GST Council.

These amendments directly impact various aspects of GST compliance, including registration procedures like Aadhaar authentication, ensuring the legal framework remains robust and responsive to evolving needs.

What are the “Services Tax Rules” in the context of GST?

The term “Services Tax Rules” in the context of GST is a misnomer. Service Tax was a tax levied on services by the Central Government prior to the implementation of GST. With the introduction of the Goods and Services Tax regime on July 1, 2017, Service Tax was subsumed into GST. Therefore, there are no “Services Tax Rules, 2017.”

The rules governing the taxation of services (along with goods) are now the Central Goods and Services Tax Rules, 2017, and corresponding State Goods and Services Tax Rules, 2017, and Integrated Goods and Services Tax Rules, 2017. Any reference to “Services Tax Rules” in the post-GST era should be understood as referring to the relevant provisions within the CGST Rules, 2017, or other GST-specific rules.

Frequently Asked Questions

What is the latest September 2026 status of the Delhi High Court biometric Aadhaar direction?

The order relevant to this article was passed on 8 September 2026 in Neha v. Union of India & Ors., W.P.(C) 12210/2026 and a connected matter. The Division Bench of the Delhi High Court directed, “for the time being”, that authorities across the country should not allow any GST registration without biometric-based Aadhaar authentication. The Court also gave the authorities liberty to place practical difficulties of implementation before it and asked them to examine additional safeguards against misuse of PAN and Aadhaar details. citeturn0search0turn0search3

Important September 2026 update: the matter was listed for further consideration on 22 September 2026. Based on the latest publicly searchable reports located for this review, no subsequent order changing or finally determining the interim direction was identified by 24 September 2026. Accordingly, this article treats the nationwide biometric requirement as an interim court direction, not as a permanent amendment to the CGST Rules. Businesses should also check the latest GSTN/CBIC portal instructions before filing because implementation can involve operational changes. citeturn1search2turn1search3

What triggered the Court’s intervention?

The proceedings arose from allegations that PAN and Aadhaar particulars of innocent persons had been misused to obtain fraudulent GST registrations. The Court recorded government figures showing 2,800 such fraudulent registrations detected in 2023–24 involving ₹15,085 crore of tax evasion, and 1,654 in 2024–25 involving ₹13,109 crore of detected tax evasion. These figures were placed before the Court from a parliamentary response. citeturn0search0turn0search12

How does the Court direction differ from the existing Rule 8 framework?

Before the September 2026 interim direction, Rule 8(4A) provided for Aadhaar authentication and, for applications identified on the common portal through data analysis and risk parameters, biometric-based Aadhaar authentication, photograph capture and original-document verification at a notified Facilitation Centre. Notification No. 04/2023-Central Tax substituted Rule 8(4A) in this form. The Court’s September 2026 direction is broader in practical effect because it says that, for the time being, authorities should not allow any GST registration without biometric-based Aadhaar authentication. citeturn3search19turn3search20turn0search0
