Income Tax Notice — Overview and What to Do When You Receive One

Q: Why does the Income Tax Department issue notices?

Notices are issued for mismatches with AIS, undisclosed income, scrutiny selection, non-filing, document requests, or pending demands. Not all notices indicate wrongdoing.

Q: How do I verify if an income tax notice is genuine?

All genuine notices appear on the Income Tax e-Filing portal with a Document Identification Number (DIN). A notice without a DIN may be fraudulent.

Q: What is the time limit for responding to an income tax notice?

Section 143(1)(a): 30 days. Section 143(2): 15 days. Section 142(1): as specified in the notice. Non-response leads to ex-parte assessment.

Q: Can an income tax notice be issued after many years?

Section 143(2) scrutiny must be issued within 3 months of the filing year-end. Section 148 allows up to 3 years for cases below ₹50 lakh and up to 10 years for ₹50 lakh or more.

Q: What happens if I disagree with the assessment outcome?

Appeal to CIT(A) within 30 days of the order, then to ITAT if needed. We provide support at both appellate levels.

A Complete Guide to Income Tax Notices in India — Types, Timelines, and the Right Response Strategy

Receiving an income tax notice from the Income Tax Department can be unsettling, but it does not always signal a serious problem. Notices are issued for a wide range of reasons — from a simple request for additional information to a full-scale scrutiny assessment of your income tax return. The critical factor in every case is how quickly and correctly you respond. An ignored or incorrectly addressed notice can escalate into a demand, penalty, or prosecution.

Understanding the type of notice received — and the appropriate response — is the first step. Our income tax notice services cover the full spectrum, from notice reply and assessment support and scrutiny assessment through to appeals at ITAT and appeals to the Commissioner of Income Tax. We also provide specific guidance on Section 143(1)(a), Section 143(2), and Section 142(1) notices.

Common Types of Income Tax Notices

Section 143(1)(a) — Intimation

An automated intimation proposing adjustments to your filed return — undisclosed income, disallowed deductions, or arithmetic errors. Requires a prompt response or acceptance.

Section 143(2) — Scrutiny

A notice selecting your return for detailed examination by an Assessing Officer. Requires comprehensive documentation. Learn about our Section 143(2) response support.

Section 142(1) — Pre-Assessment Inquiry

Issued before or during assessment to request documents, information, or to file a return if not yet filed. See our Section 142(1) inquiry response service.

Section 148 — Income Escaping Assessment

Issued when the Assessing Officer has reason to believe that taxable income has escaped assessment — typically for returns filed in earlier years.

Section 156 — Tax Demand Notice

Issued after assessment proceedings are concluded, demanding payment of tax, interest, and penalties determined to be payable. A strict 30-day payment deadline applies.

Section 245 — Set-Off of Refunds

Issued when the department proposes to adjust a pending income tax demand against an existing refund due to the taxpayer. Requires a response if disputed.

What to Do Immediately When You Receive an Income Tax Notice

Note the section under which the notice is issued — this determines the nature and urgency of the response
Check the deadline specified in the notice — most notices carry a 15 to 30 day response window
Do not ignore the notice — non-response leads to ex-parte assessment, demand, and penalty
Gather all supporting documents for the income year in question before consulting a professional
Verify the notice on the Income Tax e-Filing portal to confirm its authenticity before responding
Engage a qualified CA for notice reply and assessment support to avoid inadvertent admissions

Frequently Asked Questions

Why does the Income Tax Department issue notices?

Notices are issued for several reasons: mismatch between ITR data and information reported by third parties (TDS, AIS), undisclosed income or transactions, selection for scrutiny, non-filing of returns, requests for additional documents, or pending tax demands. Not all notices indicate wrongdoing — many are routine administrative communications.

How do I verify if an income tax notice is genuine?

All genuine Income Tax Department notices are accessible on the Income Tax e-Filing portal (incometax.gov.in) under the taxpayer's account. Each notice carries a Document Identification Number (DIN). A notice without a DIN, or one not appearing on the portal, may be fraudulent and should be reported.

What is the time limit for responding to an income tax notice?

Response timelines vary by section. Section 143(1)(a) intimations allow 30 days to respond. Section 143(2) notices typically provide 15 days for the initial response. Section 142(1) notices set a deadline specified in the notice itself. Failure to respond within the stipulated period can result in ex-parte orders and demands.

Can an income tax notice be issued after many years?

The time limit for issuing a scrutiny notice under Section 143(2) is generally within 3 months from the end of the financial year in which the return was filed. For escaped income assessments under Section 148, notices can be issued up to 3 years for cases below ₹50 lakh, and up to 10 years for cases involving ₹50 lakh or more of alleged escaped income.

What happens if I disagree with the assessment outcome?

If you disagree with an assessment order, you can file an appeal before the Commissioner of Income Tax (Appeals) within 30 days of receiving the order. If the CIT(A) order is also unfavourable, a further appeal can be filed before the Income Tax Appellate Tribunal (ITAT). Our ITAT appeal and CIT appeal services cover both levels.
