The Goods and Services Tax Network (GSTN) has updated the timelines for revising the Aggregate Annual Turnover (AATO) for the financial year 2025-26. This amendment comes as GSTN enhances its system to enable the automatic updating of AATO based on GST returns submitted after the amendment window. This change aims to ensure consistency and accuracy across the various modules of the GST portal.
Taxpayers under the new schedule can file applications for AATO amendments from 1st July 2026 to 31st July 2026. Previously, the amendment facility was available during the month of May under the advisory issued on 2nd May 2022. The jurisdictional tax officer shall review the revised AATO information between 1st August and 15th August 2026.
GSTN has recommended that taxpayers check their turnover information before filing the revised request to prevent discrepancies. Taxpayers encountering any technical problems can raise a grievance via the Self-Service Portal available on the GST Portal.
GSTN has mentioned that the AATO shown on the GST portal is derived from submitted returns and is utilised for various compliance functions like eligibility for the composition scheme, e-invoicing applicability, and other threshold-based validations. If there is any mismatch in the turnover data, then it can affect system-driven compliance flags and return processing.
The amended procedure can lessen manual corrections and enhance data precision across GST records. Taxpayers are advised to ensure timely filing of GSTR-1 and GSTR-3B so that the system shows the accurate turnover and reduces the requirement for subsequent amendments.
