Error in validation

Hey Nilesh!

Category A defect in GST returns usually means some data mismatch or missing information in the return, and the return can’t be processed until you fix it. The portal generally gives a specific reason or message about what’s wrong.

Steps to resolve Category A defect:

1. Check the Defect Details:

   • Log into the GST portal and go to your dashboard.

   • Go to “Returns” > “View Filed Returns” > Click on the return with the defect.

   • You should see a message or details explaining the nature of the defect.

2. Fix the Defect:

   • Based on the message, correct the mistake in your return.

   • Common causes:

     • Mismatch in invoice data (e.g., invoice missing from GSTR-2A/2B)

     • Incorrect GSTIN or invoice number format

     • Missing mandatory fields

     • Incorrect or missing HSN/SAC codes

     • ITC claims not matching purchase records

   • You may need to amend or re-upload invoices or data as per the error.

3. Re-file the Return:

   • After correcting, submit the return again.

   • The Category A defect should disappear if the issue is resolved.
