Business GST retirns

for any liability you have to pay to govt 

for your auditor behaviour you have two choices

1. record the messages or phone conversation of your auditor then file case against him for intentionally misuses

                                                          or

2. you can change username and password by your phone number and pay tax

"... moreover the auditor handling my gst returns is not willing to share the user name and password too..."

For the above said issue, please see the attached file.

You can change your password username in gst portal with out your auditor

i agree, but the auditor has put his mobile number and email address.

so i wont get any OTP even if i try

Dear Sumitesh
kindly contact to Your jurisdiction Tax Officer , can change Email, or mobile no.

Option 1) - Go to your jurisdictional office and retrieve your credentials

Option 2) - Lodge a complaint against your auditor for misusing/withholding/forging your identity... because he has no right to put his own details in your GST registration and if he has used it, he is bound to get it altered as per your instructions

I believe 2nd option would turn out to be easier..
