S.143(2) Scrutiny S.148 Reopening IT Act 1961

How to Reply to an Income Tax Notice

A practical guide for taxpayers and tax professionals on responding to income tax notices under Section 143, 148, 156, and 270A of the Income Tax Act, 1961. Understand notice types, critical deadlines, and the strongest available defenses.

Understanding Income Tax Notices

The Income Tax Department issues notices under the Income Tax Act, 1961 to verify the accuracy of a taxpayer's return, gather additional information, demand payment of outstanding taxes, or reopen past assessments. Every notice has a specific legal basis and a strict response deadline — missing the deadline can lead to ex-parte assessment, penalty, or prosecution.

With the Faceless Assessment Scheme introduced in 2020 under Section 144B, most scrutiny proceedings now happen electronically through the e-filing portal (incometax.gov.in), meaning all notices are served digitally and replies must be submitted online.

Critical Rule

Never ignore an income tax notice. Even if you believe the notice is incorrect or issued without jurisdiction, you must respond within the stated deadline or the Assessing Officer can make a best judgment assessment against you under Section 144.

5 Most Common Income Tax Notice Types

S.143(1)

Intimation

Auto-generated after processing your ITR. Shows tax computed by the department vs. your self-assessment. No formal scrutiny involved. Respond by paying the demand or filing a rectification under Section 154 if there is an error. Time limit: 1 year from end of financial year of return filing.

S.143(2)

Scrutiny Notice

Issued when the AO selects your return for detailed examination. You must submit documents, accounts, and explanations. Can be issued within 3 months from the end of the financial year in which the return was furnished. Deadline to respond: 30 days.

S.148

Reopening of Assessment

Issued when the AO has "reason to believe" that income has escaped assessment. Requires mandatory sanction of the specified authority (PCIT/CIT). Must file a fresh return within 3 months of the notice. Limitation: 3 years (escaped income ≤₹50L) or 10 years (escaped income >₹50L) from end of assessment year.

S.156

Notice of Demand

Issued after assessment is completed, demanding payment of taxes, interest, and penalties. The taxpayer must pay within 30 days of the demand notice. Non-payment triggers recovery proceedings including attachment of property and bank accounts under Sections 220–232. Appeal to CIT(A) possible under S.246A.

S.270A

Penalty for Under-Reporting / Misreporting

Penalty of 50% of tax for under-reported income, and 200% of tax for misreported income (e.g., false entries, suppression of sales). A show-cause notice must be issued before levying penalty. You have the right to file a response explaining the discrepancy. Immunity from penalty is available under Section 270AA if you pay tax and interest within time and do not file an appeal.

How to Respond — Step by Step

1

Read the Notice and Identify the Section

Note the section number, assessment year, deadline for response, and whether it is a paper or e-notice. Download it from the e-filing portal under "Pending Actions → e-Proceedings". Verify it bears the correct PAN, assessment year, and AO details.

2

Gather Supporting Documents

Pull together your ITR acknowledgment, Form 26AS, Annual Information Statement (AIS), TIS, bank statements, books of accounts, invoices, Form 16/16A, and any investment proofs relevant to the assessment year under scrutiny.

3

Raise Jurisdictional Objections Early

Per the Supreme Court in GKN Driveshafts (India) Ltd. v. ITO [2003], you must file your return in response to a S.148 notice and then raise objections to the reasons for reopening. The AO is obligated to pass a speaking order disposing of your objections before proceeding with the assessment.

4

Draft and Submit a Structured Reply

Address each query serially. For each item: provide the explanation, cite the relevant document, and attach supporting evidence. Upload your reply and attachments through the e-Proceedings tab on incometax.gov.in. Download the submission acknowledgment for your records.

5

Seek Adjournment if Needed

If you need more time to compile documents, file a request for adjournment online through e-Proceedings. The AO has discretion to grant extensions. Document every request and response to build a procedural record.

Key Legal Defenses

Lack of Jurisdiction — S.148 Issued Without Sanction

Any notice under S.148 must be preceded by the written approval of the PCIT/CIT. If no prior sanction was obtained, the notice is void ab initio and the assessment made pursuant to it is liable to be quashed. Verify the DIN (Document Identification Number) on the notice, which became mandatory from October 2019.

Limitation — Reopening Barred by S.149

For escaped income up to ₹50 lakh, reopening is barred after 3 years from end of the relevant assessment year (for notices issued after 1 April 2021). For older notices, the limitation was 4 years (general) or 6 years (foreign income / undisclosed income). A notice issued after the limitation period is void.

Change of Opinion — Not a Valid Ground to Reopen

Reopening under S.147 is not permissible merely because the AO has changed his opinion on the same material available during original assessment. The Supreme Court in Kelvinator of India Ltd. held that there must be "tangible material" giving rise to a belief that income has escaped assessment — not a mere review of the original record.

Source of Unexplained Income Explained

High-value deposits or credits questioned under S.68 (cash credits) or S.69 (unexplained investments) can be defended by establishing the identity and creditworthiness of the source, and genuineness of the transaction, through bank records, agreements, and ITRs of the lender/investor.

S.143(2) Notice Issued Beyond Limitation

A scrutiny notice under S.143(2) must be issued within 3 months from the end of the financial year in which the return was filed. A notice issued after this period is invalid and the assessment made pursuant to it is void. Cite Lakhmani Mewal Das v. ITO if the AO proceeds despite the objection.

Faceless Assessment Procedure Violations

Under the Faceless Assessment Scheme (S.144B), the AO must issue a draft assessment order and give you an opportunity to file objections before passing a final order. Skipping this step violates natural justice and the final order is liable to be set aside.

Frequently Asked Questions

What is the time limit to reply to an income tax scrutiny notice under Section 143(2)?
You must respond to a Section 143(2) scrutiny notice within 30 days of its issuance. This is a strict deadline and failure to respond can result in an ex-parte assessment under Section 144, where the Assessing Officer determines your income without your input, often leading to a much higher tax demand.
Can an Assessing Officer reopen an assessment after 4 years?
Under Section 149 of the Income Tax Act 1961 (as amended by Finance Act 2021), an assessment can be reopened within 3 years from the end of the relevant assessment year if the escaped income is up to ₹50 lakh. For escaped income exceeding ₹50 lakh, reopening is permitted up to 10 years. A valid Section 148 notice must be preceded by sanction of the specified authority (PCIT/CIT).
What is the difference between Section 143(1) and Section 143(2) notices?
Section 143(1) is an intimation (not a notice) sent after processing your ITR, showing tax payable or refund due — it is auto-generated and does not require a formal reply beyond paying any dues. Section 143(2) is a scrutiny notice issued when the Assessing Officer wants to examine your return in detail. It requires a formal response with supporting documents and carries significant legal consequences if ignored.
What documents should I submit in response to an income tax notice?
Documents required depend on the notice type, but generally include: ITR acknowledgment, Form 26AS / AIS / TIS, bank statements for the relevant year, books of accounts, purchase/sale invoices, TDS certificates (Form 16/16A), investment proofs (ELSS, LIC, PPF), property purchase/sale documents if questioned, and any source of high-value deposits or cash transactions.
