How the correction actually works:
• Bank-level correction: for physical challans the bank can correct TAN or PAN within 7 days of deposit (not 15), and other fields such as AY, major head or minor head within 7 days. This is under the Challan Correction Mechanism (CBDT, 2011); OLTAS does not allow later TAN corrections by banks.
• After 7 days: apply to the jurisdictional TDS Assessing Officer for correction of TAN, with the challan copy, an indemnity, and confirmation from the wrong TAN holder that the challan has not been used. The AO corrects it in OLTAS.
• Online (e-Pay Tax) challans: the e-filing portal allows correction of AY, major head and minor head within the permitted window. TAN corrections still go through the AO.
• Until it is corrected:
– the challan shows as unconsumed under the wrong TAN
– your statement shows a short payment.
Avoid paying again unless the AO route is clearly delayed; interest under Sec 201(1A) runs on the shortfall.
• If you pay again to avoid interest, claim a refund of the wrong challan in Form 26B through the other TAN holder, or have it corrected.
