2. Entering Incorrect Business Name or PAN
Mistake: PAN name mismatch is one of the top reasons for rejection.
Tip: Ensure your PAN matches exactly with your business name on documents.
3. Using a Residential Address Without Proof
Mistake: Giving a home address without ownership proof or NOC.
Tip: Attach an electricity bill + NOC from the owner if the address is not in your name.
4. Uploading Blurred or Incomplete Documents
Mistake: Many users upload incomplete or unclear documents.
Tip: All uploads documents must be clear, complete and in proper file size & format (PDF/JPEG).
5. Not Including Authorized Signatory Details
Mistake: Missing authorized signatory info leads to application rejection.
Tip: Clearly add authorized person’s PAN, photo, and contact info.
6. Choosing the Wrong Business Constitution
Mistake: Selecting Proprietor instead of Partnership, or vice-versa.
Tip: Choose the correct business type matching your PAN and registration certificate.
7. Not Declaring Bank Account Properly
Mistake: Skipping bank details or entering wrong IFSC code.
