I filed an ITR-U for Assessment Year 2024–25. The self-assessment tax was fully paid under minor head 300.
However, while entering the challan details in the utility, the date of payment was entered incorrectly as 8 July 2025 instead of 8 March 2025. Due to this date mismatch, CPC did not consider the tax payment, and a demand was raised on 8 December 2025.
To correct this, I filed a rectification request under “Tax Credit Mismatch” on 12 December 2025, with the correct challan details. The rectification request is still in “Submitted” status.
Additionally, I am unable to respond to the demand with disagreement on the portal due to error code ITD EXEC 2003. A grievance has also been raised for this issue, but no response has been received so far.
At this point, I am stuck and unable to take any further action on the portal. Please let me know what should be the next steps.
ITR-U challan payment date error causing self-assessment tax credit mismatch and demand; section 154 rectification seeks relief An assessee reports a tax credit mismatch in an ITR-U for AY 2024-25 arising from an incorrect challan payment date entered in the return utility, resulting in non-grant of self-assessment tax credit and consequent demand generation. A rectification application under section 154 for 'Tax Credit Mismatch' has been filed with corrected challan particulars, with the operative effect of seeking amendment of the intimation and deletion or reduction of the demand by allowing the correct tax credit. The assessee also reports inability to submit an online response disputing the demand due to a portal error, prompting a grievance; the operative consequence is that the statutory response mechanism is blocked pending system resolution or alternate escalation.
