Correcting a Deductee PAN in a TDS Statement After the One Permitted Correction

This article deals with the validation message "Correction not allowed: PAN already modified once", which appears when a deductee PAN has been corrected earlier in a TDS statement and a further correction is needed, and with a practitioner workaround that may be available.

It matters because the message leaves the tax mapped to the wrong PAN, and a deductor facing a notice or a deductee's credit claim has to find a route that keeps the records consistent. The workaround described below is a practitioner approach and not an official solution.

Why the message appears

TRACES guidance on online PAN correction states that there is only one opportunity for a valid-to-valid PAN correction. If the first correction was itself wrong, or the correct PAN is received later, the deductee record is locked against a second change. The consequences are practical:

• the tax remains mapped to the wrong PAN;
• the correct deductee does not receive credit;
• challan utilisation becomes hard to reconcile;
• repeated attempts are rejected by the FVU.
