How long does GST registration take, and what causes delays?
GST registration typically takes 7 working days from the date of a complete, error-free application with successful Aadhaar authentication. If Aadhaar authentication fails or is skipped, the application is routed to mandatory physical verification of the business premises, which can extend the timeline to up to 30 working days.
The standard 7-working-day timeline
Once Form REG-01 is submitted with all required documents and the primary authorised signatory completes Aadhaar-based e-KYC successfully, the application typically moves through officer review and approval within 7 working days, assuming no query is raised.
What triggers the extended 30-day timeline
If Aadhaar authentication is not completed, or the officer flags the application for physical verification of the declared business premises for any other reason, the timeline extends to up to 30 working days, since a field officer must visit and confirm the premises before approval.

Talk to a CA →Officer queries (Form REG-03) reset the clock
If the reviewing officer has doubts or finds a discrepancy — a mismatched address proof, an illegible document, or a name inconsistency between PAN and the application — they issue a query in Form REG-03. The applicant has 7 working days to respond via Form REG-04. A late or unsatisfactory response can lead to rejection, requiring a fresh application from scratch.
The most common causes of delay in practice
In practice, the most frequent causes of delay are: address proof that doesn't clearly match the declared business address, uploaded documents that are cropped, blurry, or in the wrong format, a mismatch between the applicant's name across PAN, Aadhaar, and the application form, and failure to respond to a REG-03 query within the 7-day window.
How to keep your application on the fast track
Ensure the primary authorised signatory's Aadhaar-linked mobile number is active and accessible for OTP verification, double-check that the declared business address exactly matches the supporting proof document, upload clear, complete scans of every document, and monitor the GST portal daily for any officer query so you can respond within the 7-day window rather than risking rejection.
What happens if I don't respond to a GST registration query in time?
If you don't respond to a Form REG-03 query within 7 working days, the officer can reject the application. A rejected application means starting the entire registration process over from a fresh Form REG-01 submission — there is no simple way to revive a rejected application. Set a reminder to check the GST portal regularly after submitting your application so you don't miss a query window.
