If the aggregate annual turnover shown on the GST portal is wrong and the person does not amend it, the system may keep showing an incorrect figure until it is corrected, and that can affect classification, scrutiny, and how the department views the taxpayer’s compliance profile. GSTN’s advisory says the turnover is based on filed returns, can be updated by the taxpayer, and unamended discrepancies may ultimately be reviewed by the jurisdictional officer.

What can happen

  • The portal may continue reflecting the wrong turnover in the taxpayer dashboard.
  • If the mistake is material, it may create issues in return filing, scheme eligibility, or department queries.
  • The jurisdictional officer can review and amend the figure if discrepancies are found after the update window.
  • If no correction is made, the mismatch may remain on record and may require explanation during scrutiny or notice-based proceedings.

Practical risk

A wrong turnover figure is not just a display problem; it can influence how GST compliance is interpreted. In one GST advisory, the turnover displayed on the portal was described as dynamic and based on returns filed, with a facility for taxpayers to raise a ticket if the value is incorrect. Forum discussions also note that incorrect turnover reporting can lead to avoidable compliance issues if left uncorrected.

What to do

  1. Compare the portal figure with books of accounts and filed returns.
  2. Use the update/rectification option on the portal if available.
  1. Raise a grievance ticket through the GST support/self-service route if the figure still does not match.
  1. Keep working papers and reconciliation ready in case the department asks for clarification.

Bottom line

If the wrong aggregate annual turnover is not amended, it may stay incorrect on the GST portal and can later become a compliance or explanation issue. The safer approach is to correct it early and retain evidence of the correct turnover and the correction request.

The information gathered from public internet sources indicates that the portal turnover can be updated, but uncorrected discrepancies may be reviewed by tax officers later.

TL;DR: Wrong turnover should be corrected promptly, because leaving it unamended can create mismatch, scrutiny, and explanation problems later.
