Income Tax Notice Received? 7 Things You Should Check Before Replying

You open your inbox, see "Income Tax Department" in the sender line, and your stomach drops a little before you've even read the subject. That reaction is normal, but it's also usually unnecessary. A notice is a question, not a verdict — and how you answer it matters far more than the fact that it arrived at all.

"Most people lose more money panicking over a notice than they ever would have paid by simply reading it carefully first."

What an income tax notice actually is

An income tax notice is a formal communication from the department asking you to clarify, correct or explain something about your return — it is not, by itself, a penalty, a fine, or proof of wrongdoing. If you've never read a plain notice basics explainer before, now is a good time. Think of it closer to a query raised by a bank when a transaction looks unusual: sometimes it's a genuine issue, sometimes it's just a data mismatch that needs a two-line explanation.

The department's systems now cross-check your AIS data against what you actually declared, and a large share of notices exist purely because these two numbers didn't line up. That's a process issue far more often than it's a fraud issue — our deeper piece on AIS tracking explains how that comparison actually works behind the scenes.

The sections you're most likely to see

Not all notices carry the same weight. Knowing which section you're dealing with changes how urgently and how carefully you need to respond.

Section 143(1) — intimation

This is the most common one, generated automatically after your return is processed. It flags arithmetic errors, TDS mismatches, or deduction claims that don't match third-party data. Most of these are routine and resolve with a quick correction.

Section 139(9) — defective return

Your return had a structural problem — a missing schedule, an unmatched balance sheet, an incomplete form for your income type. You typically get a fixed window to refile correctly, or the original return can be treated as invalid.

Section 142(1) — inquiry before assessment

The department wants specific documents or a return you haven't filed yet. This is more procedural than accusatory, but ignoring it has real consequences since it can precede a deeper assessment.

Section 148 — income escaping assessment

This is reassessment territory — the department believes some income wasn't reported in a past year. It carries more weight than a routine notice and usually deserves careful, documented handling rather than a quick reply.

Section 143(2) — scrutiny

Your return has been selected for detailed manual examination, often through an automated risk-based selection process. It doesn't mean you're suspected of anything specific, but it does mean every claim in your return may be examined closely — our broader note on the scrutiny process covers what that examination actually looks like.

The 7 things to check before you reply

Before you type a single word of a response, work through these in order. Skipping steps here is how simple notices turn into drawn-out back-and-forth.

1. Confirm it's genuine, on the portal itself

Fake notices circulating by email and WhatsApp are common enough that this step isn't optional. Log in directly to the e-filing portal and check whether the same notice appears under your account, with a matching Document Identification Number.

2. Note the exact section and assessment year

A notice for AY 2024-25 needs a completely different response than one for AY 2022-23. Confusing the year is a surprisingly frequent, entirely avoidable mistake that wastes your own response window.

3. Read what's actually being flagged — not what you assume

People often skim the first line and jump to conclusions. Read the specific discrepancy line item; it's usually narrower and more specific than the alarming tone of the subject line suggests.

4. Check the response deadline precisely

Deadlines are usually counted in calendar days from the date of issue, not the date you opened the email. Mark it immediately rather than estimating it later from memory.

5. Cross-check AIS, Form 26AS and Form 16 against your filed return

Most mismatches trace back to one of these three documents disagreeing with what you declared. Pull your Form 26AS directly rather than relying on memory.

6. Don't assume it's a mistake and ignore it

Even notices that look like obvious system errors need an acknowledgment or response within the window. Assuming the department will "figure it out" on its own is the single costliest assumption people make. For official section wording rather than a forwarded summary, the department site is the clearest reference.

7. Don't reply emotionally or admit anything you're unsure of

A defensive, rushed, or guilt-laden reply can create problems that didn't exist in the original notice. State facts, attach proof, and leave speculation out entirely.

Common mistakes people make when replying

Beyond the seven checks above, a few patterns show up again and again. Replying before gathering every supporting document means you often end up submitting a second clarification anyway, which just extends the whole process. Another frequent error is treating the notice reply like a conversation rather than a formal submission — vague language where a specific figure or date was needed rarely helps your case.

People also sometimes confuse a notice with a demand. If an outstanding demand notice is involved, that's a separate and more time-sensitive matter than a general clarification request, and it's worth reading our note on demand notices specifically if that's what you're facing.

How to actually submit a response on the portal

Once you know what's being asked, the submission process itself is fairly mechanical. The four steps below cover the full reply process from start to finish.

1. 01

   Verify the notice is genuine on the e-filing portal

2. 02

   Understand exactly which section and discrepancy applies

3. 03

   Gather AIS, 26AS, Form 16 and any supporting proof

4. 04

   Submit your response under e-Proceedings within the deadline

Responses are submitted under the e-Proceedings tab, where you select the relevant notice and choose from the available response options — agree with the discrepancy and file a revised return, or disagree and provide an explanation with documentary support. Keep acknowledgment numbers from every submission.

• Verify the notice's authenticity before reacting to it at all.
• Identify the exact section, assessment year and deadline.
• Match the flagged discrepancy against AIS, 26AS and Form 16.
• Decide whether a revised return or a factual explanation fits better.
• Keep a copy of every document and acknowledgment number submitted.

What happens if you miss the deadline

Missing the response window doesn't make the notice disappear — it usually narrows your options. The assessing officer can proceed with a best-judgment assessment using whatever data is already available, which is rarely in your favour. Depending on the section, additional interest or penalty provisions can also apply, and in scrutiny or reassessment cases, a missed deadline can mean losing the chance to present evidence informally before matters escalate further.

If you've already missed a deadline, don't assume the window has closed completely — a delayed but well-documented response is still often better than silence, and in some cases a condonation request is possible depending on the circumstances.

When to handle it yourself vs when to get professional help

A straightforward 143(1) intimation about a small TDS mismatch, where the numbers are easy to reconcile from your own Form 16, is usually fine to handle on your own. The portal's guided response flow is built for exactly this kind of case.

Scrutiny notices, reassessment under Section 148, anything involving multiple assessment years, or disputes over large sums are where professional input earns its cost quickly. Misjudging the strength of your own explanation in those cases can be far more expensive than the fee for getting it reviewed properly. If the underlying issue is really about correcting a filed return rather than disputing the notice itself, our guide on revised return options is worth reading alongside this one.

A quieter habit that prevents most notices

The single biggest preventive step is checking your AIS and tax liability before you file, not after a notice forces you to. Most of the mismatches that trigger a notice were visible in AIS weeks before the return was even due — they just went unchecked.

It's also worth revisiting how TDS gets deducted through the year, since a chunk of notices trace back to payslip-stage mismatches that could have been caught long before assessment time — our piece on avoidable TDS losses covers exactly this pattern.

How Tax Sahi Hai Can Help

Reading a notice correctly and responding to it correctly are two different skills, and most of the stress people feel comes from not being sure they've got either one right.
