Section 143(1)(a) — Summary Assessment & Intimation
Primary Cause: Mismatches between claimed TDS vs 26AS/AIS, arithmetic calculation discrepancies, or deduction rejection.
Statutory Framework of Faceless e-Proceedings in 2027
The Income Tax Department has modernized its audit apparatus through automated algorithms, the National Faceless Assessment Centre (NFAC), and real-time Statement of Financial Transactions (SFT) feeds. Every transaction—from share sales and credit card payments to mutual fund dividends—is tracked in your Annual Information Statement (AIS).
When differences occur between your filed ITR and the data fed by banks, mutual fund registrars (CAMS/KFintech), or employers, the system generates automated notices. Understanding the statutory section cited on the top-right header of your notice is the first step toward swift resolution.
SOP Protocol: Filing an Online Section 154 Rectification Request
Navigate to ‘Services’ > ‘Rectification’ > ‘New Request’. Select ‘Income Tax’ and choose the Assessment Year.
Choose from: ‘Reprocess the Return’, ‘Tax Credit Mismatch Correction’, or ‘Return Data Correction (Offline/Online)’.
If TDS credit was missed due to late filing by your employer or bank, verify that updated 26AS shows the deducted tax before submitting.
Once submitted, a 15-digit acknowledgement number is generated. The CPC will process the request and issue a revised 154 Order within 30 to 60 days.

“Never ignore a Section 143(1) intimation showing a demand, even if it is just ₹1,000. Interest under Section 220(2) compounds continuously. If it is an erroneous denial of 80C or TDS credit, filing a Section 154 rectification takes under 10 minutes on the portal.”
“Under Section 139(9), the 15-day timeline is jurisdictional. If you miss the window, the return becomes void ab initio. If you need more time to audit books or fetch statements, submit an online adjournment request before day 15 expires.”
“Got an inquiry notice for high-value transactions in AIS? Don't panic. 80% of mismatches stem from joint accounts, duplicate broker reporting, or mutual fund switchovers. Submit AIS feedback on portal before filing ITR.”
“Checking Section 245 notices is critical. Often, old erroneous demands from 2012 or 2014 sit in the system and eat away your legitimate current year refund. Dispute them with past challan receipts immediately!”
