The GST Appellate Tribunal (GSTAT) has fixed June 30 as the deadline for filing appeals against GST orders passed before April 1, 2026, and no appeals will be accepted after the portal closes, GSTAT Bihar vice-president Manoj Shankar said at an awareness programme organised by the Bihar Industries Association (BIA) in Patna on Tuesday. Addressing industrialists, traders, tax professionals and taxpayers, Shankar said GSTATS are now operational across the country and urged eligible taxpayers to file appeals well before the deadline to avoid last-minute difficulties.
