Govt extends GSTAT appeal filing deadline to July 31, amid surge in filings

The Centre has extended the deadline for filing appeals before the Goods and Services Tax Appellate Tribunal (GSTAT) by a month to July 31, 2026, after a sharp rise in last-minute filings led to technical difficulties on the GSTAT portal.

In a notification issued on Tuesday, the government said taxpayers can now file appeals under Section 112(1) read with Section 112(3) of the Central Goods and Services Tax (CGST) Act until July 31, instead of the earlier deadline of June 30, 2026.

The previous cut-off date had been notified on September 17, 2025, giving taxpayers several months to prepare and submit their appeals. However, according to the government, a large number of businesses waited until the final days, resulting in a heavy load on the portal.

The government said it received representations from taxpayers, tax professionals and other stakeholders highlighting technical issues caused by the sudden spike in traffic on the GSTAT portal. It noted that nearly 30,000 appeals were filed during the last 15 days before the original deadline, with daily filings reaching a peak of 5,500 appeals.

Considering these concerns, the government decided to grant an additional month for filing appeals, giving taxpayers more time to complete the process without facing portal-related disruptions.

Despite the extension, the government advised taxpayers not to postpone their filings until the last date. It urged businesses to plan their appeal submissions well in advance to avoid technical glitches and reduce pressure on the portal as the revised deadline approaches.

Key forum for GST disputes

The GST Appellate Tribunal is the second appellate authority under the GST framework and hears appeals against orders passed by the first appellate authority. The tribunal plays a crucial role in resolving indirect tax disputes and providing businesses with a specialised forum for litigation under the GST regime.

Industry had long sought the operationalisation of the tribunal to reduce the burden on High Courts and ensure faster disposal of tax disputes. Since the appeal filing window opened, taxpayers across sectors have been moving pending cases to the tribunal.

The latest extension is expected to benefit businesses that could not complete their filings because of the portal congestion, while also helping authorities manage the flow of appeals more efficiently over the next month.
