Centre has extended the last date for filing appeals before the Goods and Services Tax Appellate Tribunal (GSTAT) to July 31, 2026, giving taxpayers an additional month to submit their cases after a surge in filings led to technical difficulties on the GSTAT portal. The extension applies to appeals filed under Section 112(1) read with Section 112(3) of the Goods and Services Tax (GST) law. The revised deadline replaces the earlier cut-off of June 30, 2026, which had been notified by the government on September 17, 2025.
