What Happens If You Ignore an Income Tax Notice?

No, you cannot safely ignore an income tax notice: every notice carries a deadline, and missing it lets the Assessing Officer decide the outcome without you. Ignoring a notice does not make it lapse; it converts a routine, often minor query into a confirmed demand, penalty, interest, and possible recovery or prosecution. Most notices (a Section 143(1) intimation or a Section 142(1) inquiry) are resolved with a simple, timely reply on the e-filing portal. The cost of responding is a few hours; the cost of silence is a best-judgment assessment under Section 144 and the penalties set out below.

Most of what arrives is routine, one of several types of income tax notices the department issues, so the honest question is not whether to ignore it but which of three situations you are in. If you think the notice is wrong, you dispute it on the portal. If you cannot pay, you ask for a stay or instalments. If you are simply scared and hoping it disappears, you seek more time. Each of the three has a reply path that costs far less than silence.

There is no safe way to ignore a notice, only a right way to respond to it.

Ignoring an income tax notice escalates it through a fixed sequence: a reminder, then a best-judgment assessment under Section 144, then a demand under Section 156, then interest and penalty, and finally recovery action such as bank-account attachment under Section 226(3). The exact penalty depends on which notice you ignored: a ₹10,000-per-default penalty under Section 272A(1)(d) for a 142(1) or 143(2) notice, an under-reporting or misreporting penalty of 50%–200% of tax under Section 270A on the resulting addition, and 1% monthly interest under Sections 234B and 220(2). The table below maps each notice type to what silence triggers.

The order is fixed: a reminder first, then a best-judgment assessment under Section 144, then a demand under Section 156, then 1% monthly interest under Section 220(2) and a Section 221 penalty, then recovery under Sections 222 and 226(3). Prosecution sits only at the far end of that ladder, and only for wilful defaults.

If you ignore a Section 143(1)(a) proposed-adjustment intimation, the adjustment is made automatically once the 30-day response window closes, and the extra tax it computes becomes a demand payable under Section 156. Section 143(1)(a) gives you 30 days to accept or contest a proposed adjustment (for a mismatch with Form 26AS/AIS, a disallowed deduction, or an arithmetical error); silence is read as agreement. You lose the cheapest possible fix (a free online response or a Section 154 rectification) and instead inherit a confirmed demand plus interest under Sections 234B and 234C, and, if the adjustment reflects genuinely under-reported income, exposure to a 50%–200% penalty under Section 270A.

Here is what silence actually does, in three steps:

1. The 30-day clock runs from the date the 143(1)(a) intimation is served on you.
2. No response by day 30 means the proposed adjustment is treated as accepted, with no hearing.
3. The extra tax is added and issued as a demand under Section 156, now payable with interest.

A full Section 143(1) intimation and 143(1)(a) adjustments work differently from this proposed-adjustment stage: the department must issue a 143(1) intimation within 9 months from the end of the financial year in which the return is filed, and where that intimation itself shows a demand, you get 30 days to pay or rectify it.

Section 143(1)(a): if you do not respond within 30 days, the proposed adjustment is treated as accepted and becomes a demand.

Ignoring a Section 139(9) defective-return notice makes your return invalid (treated as if it was never filed), while ignoring a Section 245 refund set-off notice lets the department adjust your pending refund against an old demand without your consent. Section 139(9) gives you 15 days (extendable on request) to fix a defect such as a missing schedule, unpaid self-assessment tax, or an inconsistency; if you don't, you lose your refund and the right to carry forward losses and become exposed to the ₹5,000 late-filing fee under Section 234F (₹1,000 if income is up to ₹5 lakh). Section 245 gives you about 21–30 days to object to a proposed set-off; if you stay silent, your objection window closes, silence is treated as agreement, and the refund is adjusted against the demand automatically.

Both are the "soft" notices people wrongly assume are safe to ignore because neither raises an immediate rupee demand, yet each carries a real, quantifiable cost. An uncured 139(9) defect can drag you into full non-filing territory, including the Section 234F fee, the loss of loss carry-forward, and, if the return was itself due, Section 276CC exposure. A Section 245 set-off follows a response window, so a timely objection recorded on the portal under Pending Actions → Response to Outstanding Demand can stop or reduce the adjustment; ignore it and you forfeit that chance entirely.

An ignored 139(9) notice deletes your return; an ignored 245 notice deletes your refund.

A best-judgment assessment under Section 144 is an assessment the Assessing Officer completes on their own estimate of your income when you fail to respond to a 142(1), 143(2), or return-filing notice. Because it is made without your explanations or evidence, the AO uses the least favourable reasonable view: disallowing deductions, treating unexplained credits as income, and applying the data already on file (AIS, Form 26AS, bank reports). The resulting tax, plus interest under Sections 234A and 234B, is then demanded under Section 156. A Section 144 order can be appealed before the Commissioner (Appeals), but you argue from a worse position than if you had simply replied on time.

Section 144 is the pivot that turns "ignoring" into a number. It is what the Assessing Officer reaches for once you have not complied with a 139, 142(1) or 143(2) requirement, and it is the reason a routine query becomes a hard demand you then have to litigate rather than explain away.

The penalty for not complying with a notice under Section 142(1) or 143(2) is ₹10,000 for each such failure, levied under Section 272A(1)(d) of the Income-tax Act, 1961. This is the current provision for defaults from AY 2017-18 onward; the older Section 271(1)(b) no longer applies to these defaults. Separately, if the ignored notice leads to under-reported income being added, Section 270A imposes a penalty of 50% of the tax on under-reported income, rising to 200% for misreporting. Non-filing of a return is charged a late-filing fee of ₹5,000 (₹1,000 if total income is up to ₹5 lakh) under Section 234F, the fee that replaced the old Section 271F from AY 2018-19.

These are three different penalties that readers routinely conflate, so it helps to keep them apart:

The distinction matters because both 271(1)(b) and 271F are legacy provisions: a writer inheriting the older figures would cite the wrong section for a current default, which is exactly the error to avoid on a live notice.

An unpaid income tax demand attracts interest at 1% per month (or part of a month) under Section 220(2), running from the day after the 30-day payment window in the Section 156 demand notice expires. This is on top of any interest already charged under Sections 234A (late filing, 1%/month), 234B (default in advance tax, 1%/month) and 234C (deferment of advance tax) that fed into the demand itself. Interest under Section 220(2) keeps accruing every month until the demand is paid, so a demand left unpaid for a year silently grows by 12%. Paying or formally disputing the demand within 30 days stops this clock.

The first three interest sections are assessment-stage costs already baked into the demand; Section 220(2) is the separate, ongoing cost of ignoring it. A worked example shows how quickly it adds up.

An assessment order raises a demand of ₹1,00,000. The Section 156 notice is dated 1 May 2026 and gives 30 days, so payment is due by 31 May 2026. The taxpayer ignores it, and interest under Section 220(2) at 1% per month begins on 1 June 2026. After 10 months unpaid, to 31 March 2027, the interest is 1% × 10 × ₹1,00,000 = ₹10,000, taking the balance to ₹1,10,000, all before any Section 221 penalty of up to a further ₹1,00,000.

Yes: if a demand stays unpaid, the Income Tax Department can attach your bank account, salary, and other assets to recover it, without going to court. Once you are treated as an assessee in default under Section 220(4), the Tax Recovery Officer can issue a garnishee notice under Section 226(3) directing your bank (or any debtor, tenant, or employer) to pay your money straight to the department, and can attach and sell property under Sections 222–227. The department can also provisionally attach assets under Section 281B even before recovery, to protect revenue. These are the actions behind the "frozen bank account" stories: they follow silence on a Section 156 demand, not a first notice.

The recovery chain runs in a plain order: default under Section 220(4), a recovery certificate to the Tax Recovery Officer under Section 222, then modes of recovery including a Section 226(3) garnishee on your bank or employer and attachment and sale of property, with provisional attachment under Section 281B available alongside. Recovery follows an unpaid demand, not an inquiry notice, and a stay of demand during appeal or an approved instalment plan halts it. The mechanics of paying or disputing that demand live at Section 156 demand notice: how to pay or dispute it.

Bank-account attachment happens under Section 226(3), after a Section 156 demand is ignored, not after a first notice.

Prosecution is possible but reserved for serious, wilful defaults, most notably failing to file a return. Under Section 276CC, wilful failure to furnish a return can be punished with rigorous imprisonment of 6 months to 7 years (where the tax sought to be evaded exceeds ₹25 lakh) or 3 months to 2 years (in other cases), plus a fine. Wilfully attempting to evade payment of an assessed demand is punishable under Section 276C(2) with imprisonment of 3 months to 2 years, and failure to produce accounts or documents called for under Section 142(1) can attract Section 276D. Routine non-response to a 143(1) intimation does not, by itself, lead to prosecution; ignoring repeated demands and hiding income does.

The punishment scales with how deliberate the default is, and Section 276CC carries two safe harbours worth knowing: there is no prosecution if the return is furnished before the end of the assessment year, or if the tax payable after TDS and advance tax is ₹10,000 or less.

Instead of ignoring a notice, respond on the e-filing portal before the deadline: even a request for more time counts as a response and stops the clock toward a Section 144 assessment. Log in at incometax.gov.in, open Pending Actions → e-Proceedings to read the notice and its deadline, authenticate it first if you are unsure it is genuine, and then either comply (upload documents), agree and pay, or disagree with reasons and supporting proof. If you cannot pay a demand, apply for a stay or instalments rather than staying silent. If the notice involves scrutiny (143(2)), reassessment (148) or a large demand, engage a Chartered Accountant before replying.

Do this today:

1. Open Pending Actions → e-Proceedings on the portal and note the exact deadline; if the notice looks unfamiliar, check and authenticate the notice online before acting.
2. Decide your position: comply, agree and pay, or disagree with proof, and gather the documents for it.
3. Submit your response, or a request for more time, before the deadline, following how to respond to an income tax notice on the e-filing portal.
