Frequently Asked Questions

Why was my GST registration rejected when my documents were genuine?

Most rejections come from mismatches rather than fake documents: the name on PAN differing from Aadhaar or the incorporation certificate, an address proof that does not match the address typed in the application, or a vague description of the business. Another common cause is not replying to the REG-03 query within 7 working days. The REG-05 order lists the exact reason.

Is there a waiting period before I can apply again after a rejection?

No. You can file a fresh Form REG-01 as soon as you have fixed the problems named in the REG-05 order, and the new application gets a new TRN and ARN. Correct the root document first, for example updating the name on PAN or Aadhaar, or getting a fresh rent agreement, so the same query does not come back.

Can I appeal against a GST registration rejection instead of reapplying?

Yes. An appeal under Section 107 can be filed on the GST portal within three months of the REG-05 order, extendable by one month for sufficient cause. It suits cases where you had submitted proper documents and a complete REG-04 reply but the officer still rejected the application. For simple document gaps, reapplying is usually faster.

How can I avoid a REG-03 query on my address proof?

Upload a recent electricity bill, property tax receipt or municipal khata for the exact premises, plus a rent or lease agreement if rented. If the property belongs to someone else, add a signed consent letter from the owner. Make sure the door number, street and pin code match across every document and the application form.
