GSTAT Appeal Filing: Staggered Schedule and Process, Step-by-Step Process to file appeal on GSTAT

The GST Appellate Tribunal (GSTAT) has introduced its new e-filing portal to facilitate the filing of second appeals. The portal was developed by the National Informatics Centre (NIC) and was launched by the Finance Minister Nirmala Sitharaman on Wednesday.

The portal operates on a staggered filing system for which GSTAT has issued a staggered schedule for submissions. The staggered timelines will help avoid technical issues and ensure that older appeals get handled and resolved first. The schedule is as follows:

The final deadline for filing is June 30, 2026, for all cases. The GSTAT also made it clear that for appeals filed before the Appellate authority or notices of the Revisional authority, where the ARN/CRN is not available in the GSTN system, the filing window will open from Midnight of December 31, 2025, and will end on June 30, 2026.
