GST registration biometric Aadhaar requirements have entered a new legal state after the Delhi High Court issued an interim nationwide direction that GST registration should not be granted without biometric-based Aadhaar authentication. The important qualification is that a court direction and a fully documented GST portal rollout are not the same thing. TPS has not found a new GSTN or CBIC implementation advisory showing that every applicant now follows one identical biometric-centre process.
For a new GST applicant, the safest current answer is therefore two-part: the legal expectation has changed, but the exact operational steps still depend on the live GST registration workflow and any instructions generated for the individual application.
What did the Delhi High Court direct?
Current legal and national reporting consistently describes an interim Delhi High Court direction applying across India. Authorities were directed not to allow GST registration without biometric-based Aadhaar authentication. The matter is not a final judgment: authorities were also permitted to place practical implementation difficulties before the court, and further consideration is scheduled for September 22, 2026.
Was biometric Aadhaar new to GST registration?
No. Biometric-based Aadhaar authentication was already part of the GST registration framework before this court direction. Existing GST rules and official GSTN material describe biometric verification within a risk-based and phased registration system. Some applicants could be selected for biometric Aadhaar authentication and document verification based on data analysis and risk parameters.
That distinction matters because the September court direction is broader than the previously documented risk-selected model. An older answer saying biometric verification applies only when the system identifies an applicant as risky is therefore no longer sufficient on its own.
Has GSTN already changed the portal for every applicant?
TPS did not find a reviewed GSTN or CBIC advisory that establishes one new nationwide workflow for every applicant after the court direction. Existing official tutorial material still reflects the earlier Aadhaar-authentication and verification framework.
This means applicants should not assume, without a current portal instruction, that every fresh registration automatically requires an immediate visit to a biometric centre or that every earlier OTP or alternate verification pathway has already disappeared.
Do you need to visit a GST biometric centre now?
The court direction establishes the biometric requirement at the legal level, but the reviewed evidence does not establish a universal centre-visit procedure for every applicant today. Whether an applicant receives a biometric appointment, document-verification instruction or another portal step should be determined from the live GST application workflow and current official communication for that application.
What should a new GST applicant do now?
Complete the GST REG-01 process using the instructions currently shown on the GST portal. If the application generates a biometric Aadhaar authentication or verification requirement, follow that instruction and preserve the acknowledgement, ARN and related communications. Do not assume that an exemption applies, or that a physical visit is compulsory, unless the current portal or competent GST authority tells you so.
If you are already in the middle of registration, do not restart or abandon the application merely because of a headline about the court order. Check the status and instructions attached to your existing application first.
What about applicants who cannot use Aadhaar?
The reviewed material does not yet establish how every existing exemption, non-Aadhaar scenario or alternate verification route will operate under the interim nationwide direction. TPS is therefore not treating those pathways as cancelled or preserved universally until controlling implementation guidance is available.
Why the distinction between court order and portal status matters
The court can direct authorities to require biometric Aadhaar authentication, while GSTN and tax authorities still need to translate that direction into operational portal steps, appointment processes, exception handling and administrative instructions. Reporting the first as if the second is already fully complete would overstate the current evidence.
What happens next?
The Delhi High Court matter is currently listed for further consideration on September 22, 2026. Before then, GSTN, CBIC or field authorities could issue implementation instructions explaining how the nationwide direction will work in practice. Any such guidance should update this same page rather than create a second article for the same reader question.
Verification note: TPS compared multiple current legal and national reports describing the Delhi High Court direction with the pre-existing GST registration rules and official GSTN biometric-authentication material. The direct court-hosted order and a post-order GSTN/CBIC nationwide implementation advisory were not recovered in the reviewed evidence.
