One of our client was holding Service tax and Mahavat Registration. Mahavat Registration was cancelled in Oct 2016 . Service tax is continued. however Service tax provisional ID shows that Provisional ID and password is already issued by State Government. When I Login to gst portal with Provisional id and password provided by service tax department , it shows following error :
"Your RC under is cancelled, therefore, your Provisional ID stands cancelled. Hence you are not permitted to migrate under GST."
Does this mean that provisional ID provided under MAHAVAT was valid for GST migration . Since MAHAVAT number was cancelled , provisional ID got cancelled? Even though Service tax registration is still continuing.
Please advice what needs to be done? Should i contact Mahavat department or Service tax department?
