The GST portal — gst.gov.in — is down for everyone as of Monday, April 20, 2026, with a server status check confirming the site is returning no response and showing zero availability. The timing could not be worse. Today is the deadline for filing GSTR-3B for the March 2026 tax period, and hundreds of thousands of taxpayers and chartered accountants across India are attempting to file their returns with the clock running out.
A server status check tool has confirmed: “Gst.gov.in is DOWN for everyone. It is not just you. The server is not responding.” The response time on the check returned as “no response” — meaning the portal is not partially degraded or slow. It is completely inaccessible.
What This Means for You
If you have been trying to file your GSTR-3B today and getting error messages, blank screens, timeouts or portal unavailability — the problem is not your internet connection, your browser or your computer. The GST portal’s server itself is down and not responding to any requests. This is a confirmed nationwide outage affecting all users simultaneously.
The server status tool shows the site has been down for approximately one minute at the time of the check, but given the volume of complaints that have been building among chartered accountants since the morning — with CAs reporting slow and unresponsive portal behaviour since the past couple of days — the actual duration of disruption is considerably longer than the latest status check window suggests.
The GSTR-3B Deadline Context
April 20 is the statutory due date for monthly GSTR-3B filers covering the March 2026 tax period. GSTR-3B is the simplified summary return through which taxpayers report their GST liabilities and discharge them. Missing the deadline attracts late fees — ₹50 per day for returns with tax liability and ₹20 per day for nil returns — making the portal’s complete failure on deadline day a serious issue for businesses and tax professionals across India.
The chartered accountant community has been raising the alarm throughout the day. Gujarat-based CA Deep Koradia earlier told ET Wealth Online that many taxpayers and professionals had been experiencing slow portal response for the past couple of days ahead of the deadline. Today’s complete server failure confirms that the underlying infrastructure issue has now crossed from degraded performance to full unavailability.
What the Government Must Do
The situation is now unambiguous. The GST portal is confirmed down for everyone on the single most important filing deadline of the month. The government has two immediate obligations — restore the portal as quickly as possible, and announce an official extension of the GSTR-3B deadline through a formal notification.
The precedent for such extensions exists and has been used before. Under Section 168 of the CGST Act, the Commissioner has the power to extend GSTR-3B filing deadlines through notification. Previous extensions have been granted during portal outages, natural disasters and during the COVID-19 pandemic. Today’s confirmed nationwide server failure is precisely the kind of documented, verifiable disruption that warrants an immediate extension announcement — taxpayers cannot be penalised for a government system failure.
What to Do Right Now
Document your filing attempt with screenshots of the error messages or the blank portal screen, including timestamps. These screenshots serve as evidence that you attempted to file within the deadline period in case any penalty dispute arises while awaiting an official extension notification.
Monitor the official GSTN Twitter handle and the gst.gov.in website for restoration updates and any official extension announcement. The Institute of Chartered Accountants of India typically circulates government notifications on deadline extensions very rapidly through its network once issued. Your CA association and professional network will be the fastest channels for official extension news when it arrives.
Do not attempt repeated rapid reloads of the portal — when the server is completely down, repeated requests add to the load and can slow restoration. Try again after 15 to 20 minutes and check the server status tool again before attempting to file.
Business Upturn will update this report as the portal status changes and if the government announces an extension of the GSTR-3B deadline.
