Self Assessment Tax Paid but Forget to mention in ITR

If you've paid self-assessment tax but accidentally omitted it from your ITR-1, and the Income Tax Department has processed it and raised a demand, there are solutions. For AY 2023-24, you might be able to revise your ITR. For AY 2022-23, since an updated return cannot be filed if it reduces tax liability, you can opt for a rectification return or submit a response to the outstanding demand by uploading the challan details. Responding to the demand online with 'Demand Paid and Challan has CIN' might be an option, though its technical effectiveness is yet to be seen.
