A Section 143(1) notice is an automated intimation sent after the Income Tax Department processes your ITR. The department electronically compares your filed return with records from employers, banks, mutual funds. And stockbrokers. This is a preliminary assessment — not detailed scrutiny under Section 143(2). The notice is automatically generated after your filed return is matched against government tax records. The department may issue it because: The Income Tax Department cross-checks your return with AIS, Form 26AS, TIS, bank interest reports. And employer filings. If differences are detected, adjustments may be made automatically. A TDS mismatch notice happens when the TDS claimed in your return does not match department records. TDS is verified through Form 26AS and employer filings. If incorrect TDS is claimed, the department may reduce your refund or generate a demand. This means the Income Tax Department believes additional tax is payable. The department recalculates tax liability and raises a demand when the processed return differs from your filed return. Important: Always verify the demand before making payment — many notices are generated due to data mismatches, not genuine underpayment. The notice is available on the official income tax portal under "View Filed Returns" or "e-Proceedings". The PDF is password-protected. The password format is: Carefully compare the notice with your original ITR, AIS, Form 26AS, salary slips, deduction proofs. And bank interest entries before taking any action. Most Section 143(1) notices are caused by avoidable filing mistakes. Taxpayers often file returns quickly without reconciling AIS, TDS, or bank income. A Section 143(1) notice is usually a routine communication sent after your ITR is processed. In many cases, it simply confirms refund status or highlights small mismatches in tax records. The most important step is reviewing the notice carefully instead of panicking. Always compare the notice with your AIS, Form 26AS, salary records. And deduction proofs before taking action.
