Nicely represented...

Thanks..... ..

Thanks Sir, I am glad you liked my post.

Notification 18/2025 introduced Rule 9A, which allows automatic approval of GST registration within 3 working days if the GST portal risk engine scores the application as low risk.

In practice, the low-risk threshold typically means:
- Applicant has an Aadhaar-verified mobile number and the mobile matches the application data.
- Business address is verified by geo-tagging during the OTP-based verification step.
- No history of cancelled registrations or tax defaults linked to the PAN or Aadhaar.

Points practitioners should note:
- Automatic approval does not mean zero scrutiny. The department can issue an ASMT-10 or ADT-01 notice later if GSTR filings show anomalies.
- If an application is flagged as high risk, the officer still has 7 working days to approve or send a query, not 3. The Rule 9A timeline applies only to low-risk.
- Address proof and business proof documents must be accurate because the portal uses these for the risk score. Mismatches (different trade name on the bank statement vs application) are the most common cause of high-risk flagging.
