AIS Mismatch
If your ITR shows lower income than AIS, the ITD system automatically flags it for review. In FY 2023-24, the ITD sent lakhs of notices based on AIS-ITR mismatches. Always reconcile AIS before filing — even if some AIS entries are incorrect, address them through the feedback mechanism and disclose correctly in ITR.6. Why TaxClue
