An income tax notice can unsettle taxpayers after they file their returns. However, many communications involve routine checks, missing details or mismatched records.
The department may request a correction, supporting documents or payment of an outstanding demand. Each notice serves a different purpose and requires a specific response.
The Income Tax Department compares returns with AIS, TIS and Form 26AS. These records help officials check income, deductions, transactions and tax credits.
Form 26AS primarily contains TDS and TCS details. Meanwhile, AIS provides wider information, including interest income and reported financial transactions. Taxpayers can also challenge incorrect information through the AIS feedback facility.
Vipin Upadhyay, partner at King Stubb & Kasiva, said, “Income tax notices should not necessarily be viewed as an indication of wrongdoing.” He described them as part of the tax verification process.
A Section 143(1) intimation communicates the outcome of return processing. It may confirm a refund, report no additional liability or create a tax demand.
The department may also propose adjustments for calculation errors or unsupported deductions. Taxpayers should compare the intimation with their ITR, AIS, Form 26AS and payment records.
A Section 139(9) notice identifies a defective return. Missing information, inconsistent figures or an income and TDS mismatch can trigger this communication.
Taxpayers must correct the listed defect within the given period. Otherwise, the department may treat the return as invalid. AY 2026-27 proceedings follow the Income-tax Act, 1961.
A Section 142(1) notice asks for information, documents or clarification. The assessing officer may request bank statements, investment details, deduction proofs or transaction records.
Taxpayers should answer every question separately. They should attach only relevant documents and keep copies of each submission.
A Section 143(2) notice concerns scrutiny assessment. The department uses this process to examine selected parts of an ITR more closely.
A scrutiny notice alone never proves tax evasion. Still, taxpayers must support the figures reported in their returns. Relevant records may include salary documents, invoices, property papers and foreign-income statements.
Section 148 covers income that may have escaped assessment. Taxpayers should check the assessment year, disputed transaction and deadline before replying.
Reassessment cases can involve complex records or legal questions. A chartered accountant or tax lawyer may help when the disputed amount is large.
An outstanding demand may arise from a TDS mismatch, interest calculation or earlier adjustment. Taxpayers should compare the demand with tax challans and filed returns.
Section 245 permits authorities to adjust a refund against unpaid tax. Authorities must send a written intimation before making that adjustment.
Taxpayers should authenticate every income tax notice before responding. The e-filing portal allows verification through the Document Identification Number or PAN and notice details.
The department generally treats communications without a DIN as invalid, subject to permitted exceptions. Taxpayers should avoid replying through unofficial links or sharing login details.
After verification, taxpayers should review the section, assessment year, questions and response deadline. They should then reconcile the ITR with AIS, TIS, Form 26AS and bank records.
A clear response should address each issue and include supporting evidence. Unrelated documents can make the submission difficult to review.
The e-Proceedings service allows taxpayers to view notices, upload documents and submit responses online. Outstanding demands appear under the “Pending Actions” section.
Taxpayers should retain the notice, response, attachments and electronic acknowledgement. Timely action can prevent a routine discrepancy from developing into a larger compliance dispute.
