Who this affects

Indian taxpayers whose Aggregate Annual Turnover figure for FY 2025-26 is wrong. AATO drives e-invoicing applicability and several thresholds, and the window to fix it is now 1-31 July 2026, with officer review to 15 August.

The change

The Goods and Services Tax Network (GSTN) issued an advisory revising the timeline for amending a taxpayer's Aggregate Annual Turnover (AATO) for FY 2025-26: the amendment window is now 1-31 July 2026 (previously a May-only window), with tax-officer review from 1-15 August 2026, following a portal upgrade that updates AATO automatically as subsequent returns are filed.

What changed in detail

The Goods and Services Tax Network (GSTN) issued an advisory revising the timeline for amending a taxpayer’s Aggregate Annual Turnover (AATO) for FY 2025-26: the amendment window is now 1-31 July 2026 (previously a May-only window), with tax-officer review from 1-15 August 2026, following a portal upgrade that updates AATO automatically as subsequent returns are filed.

What it means

A narrow but practically important portal change — AATO drives e-invoicing applicability and several thresholds, so taxpayers who believe their turnover figure is wrong now have a defined July window to correct it before it locks in for the year.
