GSTN Advisory, Dated 01-07-2026<\/strong><\/p>\n

The GST Network (GSTN) has issued an advisory\u00a0on the GST Portal revising the timeline for amending the\u00a0Aggregate Annual Turnover (AATO)<\/strong>\u00a0for\u00a0FY 2025-26<\/strong><\/span>.<\/p>\n

The change has been made due to system enhancements that now enable automatic updating of AATO after subsequent returns are filed, even after the amendment window.<\/p>\n

1. Revised AATO Amendment Window<\/h2>\n

GSTN has revised the earlier annual window for amending AATO details.<\/p>\n

For FY 2025-26<\/strong>, taxpayers will be able to file AATO amendment applications during the following period:<\/p>\n

    \n
  • Start date:<\/strong> 01-07-2026<\/li>\n
  • End date:<\/strong> 31-07-2026<\/li>\n<\/ul>\n

    Accordingly, the amendment facility will be available only during the July window.<\/p>\n

    2. Reason for Revision in Timeline<\/h2>\n

    The timeline has been revised because of system enhancements on the GST Portal.<\/p>\n

    These enhancements allow automatic updating of AATO<\/strong> when taxpayers file subsequent returns after the amendment window. This is expected to improve accuracy and reduce the need for manual intervention.<\/p>\n

    3. Verification by Jurisdictional Tax Officers<\/h2>\n

    The amended AATO details submitted by taxpayers will be subject to verification by jurisdictional tax officers.<\/p>\n

    The verification period will be:<\/p>\n

      \n
    • Start date:<\/strong> 01-08-2026<\/li>\n
    • End date:<\/strong> 15-08-2026<\/li>\n<\/ul>\n

      Tax officers will review the amended details filed by taxpayers during the July amendment window.<\/p>\n

      4. Responsibility of Taxpayers<\/h2>\n

      Taxpayers must ensure that the correct AATO details are submitted during the amendment window.<\/p>\n

      Any incorrect reporting may be subject to verification and further action by the jurisdictional tax officer.<\/p>\n

      5. Objective of the Advisory<\/h2>\n

      The advisory seeks to:<\/p>\n

        \n
      • Revise the AATO amendment timeline for FY 2025-26;<\/li>\n
      • Align the amendment process with system enhancements;<\/li>\n
      • Enable automatic updating of AATO based on subsequent returns;<\/li>\n
      • Provide a defined verification window for tax officers; and<\/li>\n
      • Ensure accurate reporting of turnover details on the GST Portal.<\/li>\n<\/ul>\n

        6. Key Takeaway<\/h2>\n

        GSTN has revised the AATO amendment timeline for FY 2025-26<\/strong>. The AATO amendment facility will now be available from 01-07-2026 to 31-07-2026<\/strong>, and amended details will be verified by jurisdictional tax officers from 01-08-2026 to 15-08-2026<\/strong>. Taxpayers should ensure that correct AATO details are submitted within the prescribed window.<\/p>\n","protected":false},"excerpt":{"rendered":"
