About GST Portal

Registration, return filing and tax payments are done on the GST Portal, and GSTN runs its own helpdesk for portal, login, filing and payment problems. Those official helpdesk details are listed here so taxpayers and their accountants reach GSTN directly.

Around return due dates the helpdesk is heavily loaded. Keep your GSTIN ready, and for anything unresolved raise it on the official self-service grievance portal, which gives you a ticket number to follow up with. GSTN does not call asking for your portal password or OTP, so any such call is a scam.

GST Portal helpline — questions

The GST helpdesk number is 1800-103-4786, covering registration, return filing, e-way bill and portal login problems.
GST helpdesk ka number 1800-103-4786 hai. Registration, return filing ya login ki problem is par batayein.
Yes, 1800-103-4786 is a toll-free number for taxpayers across India.
The helpdesk works Monday to Saturday during business hours. Around a return due date the wait is longest, so logging a ticket on the self service portal is usually quicker.
Use the GST Self Service Portal, which replaced the old helpdesk email. You log the issue, attach screenshots and get a ticket number to track, and it carries an AI assistant for common queries.
Check that the registered mobile and email on the GSTIN are current, since OTPs go only to those. If they have changed, the amendment has to be filed rather than fixed over a call.
No. Filing on the GST portal is free, and only tax and any statutory late fee are payable. If the helpline and self service portal have not resolved a complaint, CPGRAMS at pgportal.gov.in is the escalation route.
