Once the OLTAS challan correction window closes, you have two options: file a request with your Assessing Officer under Section 154 with the correct challan details, or use the TRACES portal under Request for Resolution to flag the mismatch before any demand is confirmed. Most practitioners go the Section 154 route as it creates a paper trail. If a demand notice has already been raised, pay only after confirming the correct challan is reflected in your TRACES account, otherwise the payment may not settle the demand properly.

After the online challan correction has been made, usually another online correction of the same challan is not allowed. In this way, you should go to your Jurisdictional AO with a written application and supporting details of the challan for the further correction.

In the current situation where there is unused balance available, AO correction is the practical solution for balancing the unused balance in step with demand via TRACES. Also be aware that online correction is available for unconsumed challans and only till the time limit.
