Businesses transitioning to the Goods and Services Tax (GST) regime, including those previously registered under Central Excise, Service Tax, or VAT, receive a Provisional ID and password from their respective tax authorities. This migration process can present various challenges. Below are common issues encountered during GST migration, along with their practical solutions.

Provisional ID Invalid

If your Provisional ID appears invalid, clear your browser's history and attempt to log in to the GST portal once more. A 10-digit access token should be provided with your Provisional ID. If the token contains fewer than ten digits (e.g., 7654356), prefix it with zeros to achieve the required length (e.g., 0007654356).

RC Canceled

An error message indicating “Your RC under is cancelled, therefore Provisional ID stands cancelled. Hence you are not to migrate under GST” often arises if previous Service Tax (ST) or VAT returns were not filed by their respective deadlines, preventing the relevant department from forwarding the GST Provisional ID. This issue may also occur if a Provisional ID issued before January 31, 2017, remained unused and was subsequently cancelled. To resolve this, visit the ST/VAT department in person to request manual forwarding of your Provisional ID. Alternatively, send an email from your registered address to cbecmitra.helpdesk@icegate.gov.in with the subject "PID required to migrate to GST", including your Service Tax or Excise Registration Certificate (RC) number(s) and any other migration-related concerns.

OTP Not Received

Upon completing registration, a One-Time Password (OTP) is dispatched to your registered email address and mobile number. Should the OTP not arrive, consider these steps:

• Select the "resend OTP" option.
• Verify if any "Do Not Disturb" (DND) services are active on your mobile device through your service provider; deactivate them and reattempt OTP receipt.
• Examine your email's spam or junk folder, as the message might have been redirected there.

PAN Details Incorrect

Providing inaccurate Permanent Account Number (PAN) details will result in a validation error. It is crucial to ensure that director's PAN information is entered precisely as it appears in the Income Tax Department's PAN database. This includes correctly specifying the first, middle, and last names when inputting them into the GST portal.

Range Code Error

When completing GST Form-20 on the GST Common Portal, it is essential to choose the appropriate range code. If the necessary range code is absent from the dropdown menu, try refreshing the page. Then, re-check to see if the desired range code is now visible.

Pending for Verification

If you encounter a "pending for verification" message, confirm that you have entered the One-Time Password (OTP) correctly. Additionally, ensure your Aadhaar card is linked to a valid mobile number.

ARN Not Received

Application Reference Numbers (ARNs) for all GST migrations were expected post-June 15, 2017. If you have not yet received your ARN, contact the GST Helpdesk for assistance.

DSC Not Registered

Should you encounter a "DSC Not Registered" error, implement the following solutions:

• Register your Digital Signature Certificate (DSC) on the GST Portal.
• If the issue persists, uninstall and then reinstall the DSC utility software.
• Verify your Java version; ensure it is updated and matches the required specification for the GST portal.

If these troubleshooting steps do not resolve your GST migration issues, contact the GST Helpdesk directly via email at helpdesk@gst.gov.in or by phone at 0124-4688999 for further support.
