Income-Tax Notice: What to Do in the First 48 Hours

Current position in plain English

Decision table

How to apply the rule

Use the portal statement as a starting point, not a substitute for books and supporting documents. Tax reporting follows the legal character of an amount: a bank credit may be income, a transfer, a loan, a reimbursement or a sale consideration. Label the amount before deciding its tax treatment.

Keep a year-specific working paper. The transition on 1 April 2026 means the filing date alone does not identify the governing statute. Record the income period, the applicable Act, the return or proceeding, the tax credit and the portal service used.

A good compliance file lets another professional reproduce the result. Include the taxpayer’s figure, the department or third-party figure, the difference, the explanation and the evidence reference.

For income tax notice response, first identify the legal or contractual relationship, then separate the amount, event and deadline. Use one chronology across the portal, institution and supporting records. This prevents a correct fact from being submitted under the wrong year, account, policy clause or complaint route.

Practical example

A salaried taxpayer receives a portal communication showing ₹4.8 lakh of unreported interest. The AIS includes a duplicated bank entry. The useful response is a table showing the bank, account, actual interest, duplicated amount and supporting certificate—not a one-line statement that the AIS is wrong.

Action checklist

• Download the notice and every annexure from the portal.
• Create a chronology: return filing, processing, earlier replies and current deadline.
• Prepare an issue-wise table with department amount, taxpayer amount, difference and proof.
• Check whether tax credit, income or both are disputed.
• Have the response reviewed where the amount, penalty exposure or legal section is material.
• Upload readable, indexed files and save the acknowledgement.

Evidence and document checklist

• Portal notice and DIN details
• Filed return, computation and acknowledgement
• AIS, TIS and Form 26AS for the relevant year
• Bank, employer, broker, property or business records
• Prior submissions and departmental orders
• A copy of the final response and acknowledgement

Common mistakes

• Replying to an email without checking the portal
• Uploading a document dump without an index
• Changing figures merely to match AIS without checking facts
• Ignoring an attachment or question number
• Using the wrong year or wrong Act in the response
• Making unsupported admissions

Red flags

Escalation route

Use the e-Proceedings service shown in the notice. For portal or service failure, preserve screenshots and raise an e-Filing grievance. Obtain professional representation for high-value or legally complex matters.

When escalating, include the original complaint, acknowledgement, concise chronology, disputed amount, rule or clause relied upon and the exact relief requested. Do not send passwords, PINs, OTPs or unrelated identity documents.
