When taxpayers receive an I-T notice, the first step is to verify its authenticity through the official income-tax e-filing portal. According to the Income Tax Department's FAQ on "Authenticate Notice/Order Issued by ITD," taxpayers can verify the authenticity of notices, orders, summons, letters or other communications received from the department without logging in to their e-filing account. The department has mandated that every communication issued by Income Tax authorities on or after October 1, 2019, must carry a unique Document Identification Number (DIN). Taxpayers can use the authentication service by providing document type, assessment year, date of issue, and mobile number for OTP verification. The service allows three attempts to enter the correct OTP with each OTP remaining valid for 15 minutes before requiring a fresh OTP generation. As per Business Standard, the safest way to verify a notice is to log in to the Income Tax e-Filing portal and check whether it appears under 'Pending Actions', 'e-Proceedings' or 'View Notices and Orders'. Genuine emails usually come from the @incometax.gov.in domain, while legitimate SMS communications typically carry the ITDCPC sender ID.
The department uses technology and data shared by banks, employers, brokers and other reporting entities to verify returns, with notices often arising when the income reported in the ITR does not match information in AIS, TIS, Form 26AS and other databases. According to Business Standard, common triggers include unreported income, incorrect TDS or tax credit claims, errors in reporting capital gains, wrong residential status, incorrect deduction claims, non-disclosure of foreign assets or income, filing the wrong ITR form, and mismatches involving high-value transactions such as property purchases, investments and foreign remittances. Taxpayers should not rely only on Form 16 and should reconcile the ITR with AIS, TIS, Form 26AS, bank statements, capital gains statements and other relevant records before filing. The department now relies heavily on data analytics and information from the Annual Information Statement (AIS), Form 26AS and banks, so taxpayers must file accurate and complete returns to avoid notices.
The department issues several communications after taxpayers file an ITR, with most being routine and system-generated. An intimation under Section 143(1) may confirm the return, issue a refund or raise a tax demand, while a Section 139(9) notice is issued when a return is defective, such as when the taxpayer uses the wrong ITR form or omits mandatory details. According to Business Standard, a Section 143(2) notice means the return has been selected for scrutiny, requiring the taxpayer to substantiate the income, deductions and exemptions claimed, while a Section 142(1) notice seeks additional information or documents needed to complete the assessment. Taxpayers may also receive notices about defective returns, scrutiny assessments, requests for additional information, tax demands, refund-related issues or mismatches between the ITR and data in Form 26AS, AIS, the Taxpayer Information Summary (TIS), the Statement of Financial Transactions (SFT) or tax deducted at source (TDS) statements.
The department uses data analytics and information from AIS, SFT, TDS statements and other reporting mechanisms to track transactions that commonly attract attention. According to Business Standard, such transactions include property purchases and sales, large securities transactions, foreign assets and income, overseas bank accounts, large cash deposits, high-value spending such as luxury purchases or foreign travel, and unexplained gifts, loans or other financial transactions. The Assessing Officer (AO) may begin reassessment proceedings when information from data analytics, audit findings or other authorities suggests that income has escaped assessment. The AO first gives the taxpayer a notice and an opportunity to explain why reassessment should not begin, with this pre-notice hearing acting as an important safeguard ensuring taxpayers get a fair opportunity to present their case before reassessment proceedings begin.
According to Business Standard, taxpayers should read through the notice carefully and identify the issue, the relevant section and the response deadline before responding through the Income Tax e-Filing portal. The response process involves logging into the I-T portal, clicking on Pending Action, followed by e-Proceedings, where the notice can be responded to with explanation and supporting proof documents. Under the NUDGE initiative, the I-T Department may send preliminary SMSes or emails highlighting possible discrepancies and encouraging voluntary corrections before formal proceedings are initiated. Taxpayers should keep all records used to file their ITR readily available, including Form 16, bank statements, bank interest certificates, investment proofs, capital gains statements and tax payment challans. The department sends a demand notice when it determines that the taxpayer must pay additional tax, interest or penalty after it processes or assesses the return, while a Section 154 notice is issued to rectify an apparent error such as an arithmetical mistake or incorrect tax credit. Taxpayers should respond promptly to avoid interest, penalties and unnecessary litigation.
