File revised return by Dec 31 for mismatch in ITR and AIS

I have got a tax notice due to a mismatch in my income tax return (ITR) and annual information statement (AIS).

• There was an entry of interest income in AIS which was not there at the time of filing the return in July. What should I do? -Arvind Iyer

A mismatch between your ITR and AIS is common, as banks and institutions often update data later. The AIS interest entry should be checked against your bank statements or Form 26AS. If the AIS amount is correct and the income was missed, a revised return can be filed on or before December 31, 2025, with the applicable tax and interest, if any. Notably, if the entry is incorrect, feedback can be submitted on the AIS portal by marking it as a mismatch or not related to you. Responding to the notice on time with supporting documents resolves the matter smoothly.
