Important Information - Why reject the correction in Challan Details by TDS-CPC ?

Mostly, the correction in challan of TDS payment rejected by TDS-CPC we found, but can we think about that why TDS-CPC reject ? Read the following for better understanding :

Challan detail record on which correction has been filed does not exist in regular / previous statement

In a correction statement, verification keys from challan data should match with the corresponding fields in regular statement

• Verification keys for Non Nil Statement – Last transfer voucher number, Last Bank-Branch Code / Form 24G Receipt Number, Last date of transfer voucher / bank Challan, Last deposit amount as per challan
• Verification keys for Nil challan – Last date of transfer voucher number / bank challan, last total deposit amount as per challan

If an unmatched challan is being corrected, then the sum of deposit amount of all the active deductee rows in the regular and correction statement and corrected values of claimed TDS interest and claimed TDS Others amount should be less than or equal to Total deposit amount of challan given in statement

If a matched challan is being corrected, then available balance amount in the challan should be sufficient for consumption of updated sum of deposit amount of all the active deductee rows in correction and corrected values of claimed TDS interest and claimed TDS Others amount

In case of existing matched / partially matched challan, deductor can only update Cheque / DD Number, claimed TDS Interest amount, claimed TDS Others amount and Section code

If deductor updates only deductee details, then claimed TDS Interest amount and claimed TDS Others amount as given in the challan should match with the corresponding values present in regular / previous return
