Sec 270A vs Sec 271(1)(c): Penalty Regime under the Income-tax Act, 2025

Quick Answer

The Income-tax Act, 2025 carries forward the under-reporting and misreporting penalty regime originally introduced as Sec 270A under the 1961 Act. Under the Sec 270A equivalent in Chapter XXI of the 2025 Act, under-reporting of income attracts a penalty of 50% of the tax on the under-reported amount, and misreporting attracts 200%. The old Sec 271(1)(c) concealment penalty has been fully replaced and does not apply to tax year 2026-27 assessments. Immunity from penalty is available for under-reporting cases under the Sec 270AA equivalent on payment of tax and interest and non-filing of appeal.

Last Updated: 15 April 2026 | Applicable From: Tax Year 2026-27 (1 April 2026 onwards) | Reference: Income-tax Act, 2025 (30 of 2025), as amended by Finance Act, 2026

The penalty regime for income-related defaults has undergone a two-step evolution. The first step was the replacement of the old Sec 271(1)(c) of the Income-tax Act, 1961 by Sec 270A from the assessment year 2017-18, which shifted the Department from a mens-rea-based concealment test to an objective under-reporting framework. The second step was the incorporation of this framework into the Income-tax Act, 2025, which commenced on 1 April 2026 after receiving Presidential assent on 21 August 2025. Chapter XXI of the new Act consolidates all penalty provisions into a single chapter, with the Sec 270A equivalent as the principal income-related penalty and a cluster of specific default penalties carrying forward the Sec 271A/B/C/D/E/F/H equivalents. This guide explains the comparison in depth, walks through the computation with worked examples, and provides practical guidance on immunity, defence and appeal.

Definition — Under-reporting of Income: Under the Sec 270A equivalent of the Income-tax Act, 2025, a person is treated as having under-reported income where the assessed income is greater than the income declared in the return of income or, in the case of a non-filer, where the assessed income exceeds the maximum amount not chargeable to tax. Penalty is 50% of the tax attributable to the under-reported amount.

Featured Answer — Which penalty applies to me if an addition is made in assessment?

If the addition is a numeric under-reporting (omitted interest, missed capital gain, disallowed expense, wrong computation), the Sec 270A equivalent applies at 50% of the tax on the addition, and the Sec 270AA equivalent immunity is available if you pay the tax and do not appeal. If the addition involves misrepresentation, fabrication, bogus claims or undisclosed investment, the penalty is 200% of the tax and no immunity is available. If the default is a procedural failure (non-audit, non-maintenance of books, cash loan), the specific Chapter XXI equivalents of the old Sec 271A/B/C/D/E/H apply. The old Sec 271(1)(c) concealment penalty does NOT apply to tax year 2026-27 assessments — it has been fully replaced.

Background — from Sec 271(1)(c) to Sec 270A to the 2025 Act

Under the Income-tax Act, 1961, the principal income-related penalty was Sec 271(1)(c), which allowed the Assessing Officer to levy a penalty between 100% and 300% of the tax sought to be evaded for concealment of income or for furnishing inaccurate particulars of income. The provision was notoriously difficult to administer — it required the Department to prove state of mind, and courts routinely struck down penalty orders for inadequate satisfaction, non-specification of the limb of default, and absence of mens rea. The Supreme Court in CIT v. Reliance Petroproducts narrowed its scope significantly.

To address these difficulties, the Finance Act, 2016 introduced Sec 270A into the 1961 Act, effective from AY 2017-18. It replaced the subjective concealment test with an objective under-reporting framework and introduced a distinction between under-reporting (50% penalty) and misreporting (200% penalty). It also introduced Sec 270AA, giving taxpayers a statutory route to apply for immunity from penalty and prosecution.

The Income-tax Act, 2025 carries this framework forward intact into Chapter XXI. The substantive tests, the computation formula and the immunity provision all survive. The numbering has changed — the section numbers are different in the new Act — but the law is the same. For every penalty proceeding initiated after 1 April 2026, the 2025 Act provisions apply and the old Sec 271(1)(c) is dead.

Sec 270A equivalent under the 2025 Act

The Sec 270A equivalent in the Income-tax Act, 2025 has four operative limbs:

Trigger. A taxpayer “under-reports” income when the assessed income exceeds the returned income (or where the assessed income exceeds the basic exemption in a non-filer case).
Base penalty (under-reporting). 50% of the tax payable on the under-reported amount.
Enhanced penalty (misreporting). 200% of the tax payable on the misreported amount, where the under-reporting is consequent upon one of six listed acts of misrepresentation, suppression, fabrication, bogus claim, undisclosed investment or unrecorded receipt.
Exclusions. A list of exclusions where no penalty is levied, including bona fide difference of opinion, estimated additions accepted on appeal, and additions reversed on further appeal.

Under-reporting — meaning and examples

Under-reporting is the baseline trigger. It applies whenever the assessed income is higher than the returned income for reasons that do not rise to the level of misreporting. Typical examples include:

Failure to include interest on fixed deposits reflected in Form 26AS
Omission of dividend income visible in AIS
Incorrect computation of capital gain on listed equity (wrong cost, wrong period)
Wrong head classification — e.g. treating business income as capital gain
Claim of deduction under the Sec 80C equivalent without supporting documents, where the claim is otherwise bona fide
Incorrect computation of house property income
Disallowance of expenses on grounds of lack of vouchers, where the expense is real
Computation errors in depreciation calculations
Additions on account of difference between reported and assessed business profit within a reasonable band

The common thread is that the default is numeric, not dishonest. There is no fabrication, no concealment, and no bogus documentation. Under-reporting attracts a penalty of 50% of the tax on the addition.

Misreporting — meaning and examples

Misreporting is a sharper subset of under-reporting and involves active dishonesty. It applies where the under-reporting is a consequence of any of the following:

Misrepresentation or suppression of facts
Failure to record investments in books of account
Claim of expenditure not substantiated by evidence
Recording of false entries in books of account
Failure to record any receipt in books of account having a bearing on total income
Failure to report any international transaction or transaction with specified domestic parties

Typical examples:

Inflated purchases from shell or non-existent entities
Bogus HRA claim with fabricated rent receipts
Donation claims under the Sec 80G equivalent to non-existent trusts
Sham loans from benami parties
Undisclosed cash deposits during demonetisation-style events
Fabricated long-term capital gain through penny-stock price manipulation
Unrecorded sales suppressed from books
Undisclosed foreign assets and income
Failure to report specified domestic transactions in transfer pricing

Misreporting attracts a penalty of 200% of the tax on the addition, and — critically — the Sec 270AA equivalent immunity is not available.

Computation formula and worked examples

The penalty is computed in three steps. Step 1: compute tax on the assessed income including the under-reported amount. Step 2: compute tax on the income as returned. Step 3: the difference is the tax attributable to the under-reported amount, and the penalty is 50% (or 200%) of that difference. Surcharge and health and education cess are included.

Worked Example 1 — Under-reporting (50% penalty)

Mr Ashok, salaried, filed his return for tax year 2026-27 showing total income of ₹16,00,000 under the new regime. On scrutiny, the Assessing Unit found that he had omitted interest income of ₹2,00,000 reflected in Form 26AS. The assessed income is ₹18,00,000.

Tax on ₹18,00,000 (new regime slabs) = ₹1,80,000 + 4% cess = ₹1,87,200
Tax on ₹16,00,000 = ₹1,20,000 + 4% cess = ₹1,24,800
Differential tax on under-reported ₹2,00,000 = ₹62,400
Penalty under the Sec 270A equivalent (50%) = ₹31,200

If Mr Ashok pays the differential tax plus interest and does not appeal, he can apply for immunity under the Sec 270AA equivalent and the penalty is dropped.

Worked Example 2 — Misreporting (200% penalty)

Ms Bina, business assessee, filed her return for tax year 2026-27 showing total income of ₹20,00,000. Scrutiny revealed ₹5,00,000 of bogus purchases from a shell entity identified by the Investigation Wing, supported by fabricated invoices. The assessed income is ₹25,00,000.

Tax on ₹25,00,000 (new regime) = ₹3,25,000 + 4% cess = ₹3,38,000
Tax on ₹20,00,000 = ₹2,00,000 + 4% cess = ₹2,08,000
Differential tax on misreported ₹5,00,000 = ₹1,30,000
Penalty under the Sec 270A equivalent (200%) = ₹2,60,000

Immunity under the Sec 270AA equivalent is NOT available because the addition is misreporting. Total cost: ₹1,30,000 tax + ₹2,60,000 penalty + interest = approximately ₹4,50,000 on an addition of ₹5,00,000.

Worked Example 3 — Mixed addition

Mr Chandran’s assessment adds ₹3,00,000 (bogus HRA claim — misreporting) and ₹1,00,000 (disallowed interest for lack of vouchers — under-reporting). The penalty is computed limb by limb:

Misreporting addition ₹3,00,000 → 200% × differential tax
Under-reporting addition ₹1,00,000 → 50% × differential tax
Each addition is computed at the marginal rate applicable and aggregated.

Immunity under the Sec 270AA equivalent

The Sec 270AA equivalent gives the taxpayer a statutory exit route. To qualify:

The addition must fall within under-reporting (not misreporting)
The taxpayer must pay the tax and interest on the addition within the time specified in the demand notice
The taxpayer must not file an appeal against the assessment order
The taxpayer must apply for immunity within one month from the end of the month in which the assessment order is received

If granted, immunity extends to penalty under the Sec 270A equivalent and to prosecution under the Chapter XXII equivalent for the same default. The application does not bar the taxpayer from seeking rectification of mistakes apparent on record. It does, however, close the door to appeal — so the taxpayer must evaluate carefully whether the addition is worth contesting or whether the immunity route gives a cleaner closure.

Comparison with the old Sec 271(1)(c) framework

Feature	Old Sec 271(1)(c), 1961 Act	Sec 270A equivalent, 2025 Act
Trigger	Concealment or furnishing inaccurate particulars	Under-reporting / misreporting of income
Mens rea	Subjective — required to establish intention	Objective — numeric gap triggers under-reporting
Quantum	100% to 300% of tax sought to be evaded	50% (under-reporting) or 200% (misreporting)
Discretion	Wide officer discretion within the 100–300% band	Fixed rates — no discretion
Immunity	Not available	Available under the Sec 270AA equivalent for under-reporting
Litigation exposure	High — many orders struck down on procedural grounds	Lower — objective criteria reduce subjective disputes
Applicable to	AY 2016-17 and earlier	Tax year 2026-27 and onwards (and pending 270A proceedings under the 1961 Act till 2025-26)
Safe harbours	Judicially developed (e.g. Reliance Petroproducts)	Statutorily codified exclusions

When does each penalty apply

The practical rule is: the old Sec 271(1)(c) applies only to pending proceedings for AY 2016-17 and earlier that have not yet been closed. The Sec 270A mechanism (under the 1961 Act) applied from AY 2017-18 to AY 2026-27 (old terminology). From 1 April 2026, the Sec 270A equivalent under the Income-tax Act, 2025 takes over and applies to tax year 2026-27 onwards.

The transitional savings clause in Chapter XXIII ensures continuity — pending penalty proceedings initiated under the 1961 Act continue under the 1961 Act procedure until completion, but any fresh penalty arising out of an assessment for tax year 2026-27 and onwards is governed by the 2025 Act provisions.

Safe harbours and exclusions

The Sec 270A equivalent codifies several exclusions where no penalty is levied even if assessed income exceeds returned income:

Bona fide estimate — where the taxpayer had offered a bona fide estimate of income (for example, in an estimation-based head like construction contract) and the assessment differs within a reasonable range
Disclosed material — where all material facts were disclosed in the return and the only dispute is interpretational
Judicial interpretation — where the addition is based on a settled judicial interpretation contrary to which the taxpayer took a reasonable legal position
Reversal on appeal — where the addition is deleted on appeal, the penalty automatically falls
Transfer pricing adjustments — certain transfer pricing additions within the safe-harbour or arm’s length range

Successfully invoking a safe harbour requires careful factual framing in the return and in the first reply to the show-cause notice.

Procedural aspects and time limits

Penalty proceedings are distinct from the assessment proceedings and follow their own procedural rules:

Penalty is initiated in the assessment order by recording satisfaction and issuing a show-cause notice
The show-cause notice must specify whether the default alleged is under-reporting or misreporting — non-specification is a ground to quash the order
The taxpayer has an opportunity to file written submissions and request a video hearing
The penalty order must be a speaking order with reasons
Time limit: six months from the end of the tax year in which the penalty proceedings were initiated, or one year from the end of the tax year in which the appellate order is received, whichever is later

Defence strategy and appeal

Even where the quantum addition is upheld, the penalty can often be defeated. Common defences include:

Mis-characterisation — arguing that misreporting should be re-characterised as mere under-reporting (reducing the penalty from 200% to 50%)
Safe harbour — invoking the statutory exclusions for bona fide estimates, disclosed material, or judicial interpretation
Non-specification of limb — challenging the show-cause notice for failure to specify the exact default
Limitation — checking the six-month / one-year outer limit
Lack of satisfaction — arguing that the Assessing Officer did not record satisfaction in the assessment order as required
Immunity application — where the addition is under-reporting, evaluating whether immunity under the Sec 270AA equivalent is a better exit than appeal

The penalty appeal lies to the CIT(A) within 30 days under Chapter XVIII and then to the ITAT within 60 days. Stay of demand can be sought during appeal.

Expert Insight

CA V. Viswanathan: Penalty strategy under the Sec 270A equivalent is the most under-thought-through part of tax litigation in my experience. Taxpayers and their advisors focus intensely on defending the quantum addition and treat the penalty as an afterthought that will flow automatically. This is a mistake. The penalty exposure on a single addition can equal or exceed the tax, and the defence strategy should be structured from day one. My working rules are these. First, read the show-cause notice with forensic care to check whether the officer has specified the limb — under-reporting or misreporting. Non-specification is a killer defence that often works all the way to the ITAT. Second, frame your assessment reply so that even if the addition is confirmed, the factual narrative supports under-reporting rather than misreporting. The difference between 50% and 200% hinges on how the facts are presented. Third, evaluate the immunity route early. For small under-reporting additions where the quantum itself is borderline, the immunity application is often the rational exit — you pay the tax and interest, you avoid the penalty and prosecution, and you walk away from a multi-year appeal. For high-stakes misreporting cases, immunity is not available and appeal is the only route. Fourth, do not ignore the safe harbours — bona fide estimate, disclosed material, judicial interpretation are codified statutory defences and must be pleaded explicitly in the reply, not assumed to apply automatically. Finally, treat penalty as a distinct proceeding — file separate grounds of appeal, argue it separately, and never let it piggyback on the quantum appeal. Under the Income-tax Act, 2025 the framework is objective but the defences are still factual, and factual defences need factual preparation.

Frequently Asked Questions

Which penalty provision applies under the Income-tax Act, 2025?

Under the Income-tax Act, 2025, the main penalty for income-related defaults is the Sec 270A equivalent, which carries forward the under-reporting (50% of tax) and misreporting (200% of tax) framework introduced by the 2016 amendment to the 1961 Act. The older Sec 271(1)(c) penalty for concealment or furnishing inaccurate particulars has been fully replaced and does not apply to tax year 2026-27 onwards. Chapter XXI of the 2025 Act consolidates all penalty provisions.

What is under-reporting of income under the Sec 270A equivalent?

Under-reporting arises where the assessed income is greater than the income declared in the return, or where income was declared for the first time only on assessment. It covers additions for unsubstantiated deductions, incorrect computation, omitted income, wrong head classification and disallowed expenses. The penalty is 50% of the tax payable on the under-reported amount. The definition is objective — it triggers on the numerical gap between returned and assessed income.

What is misreporting of income?

Misreporting is a more serious sub-category of under-reporting. It covers misrepresentation of facts, suppression of facts, fabrication of documents, bogus claims, undisclosed investments, and failure to record receipts in books where such failure has a bearing on total income. Penalty is 200% of the tax payable on the misreported amount. Misreporting is not eligible for the immunity provision under the Sec 270AA equivalent.

How is the tax payable on under-reported income calculated?

The formula is: tax payable on (returned income + under-reported amount) minus tax payable on returned income. The difference is the tax attributable to the under-reported amount, and the penalty is 50% (or 200% for misreporting) of this difference. Surcharge and cess are included in the computation. The formula ensures that the penalty is proportionate to the marginal tax impact of the under-reporting.

What is the difference between Sec 270A and the old Sec 271(1)(c)?

The old Sec 271(1)(c) required the Department to prove concealment or furnishing of inaccurate particulars, often leading to subjective inquiries into mens rea. Sec 270A replaced it from tax year 2017-18 onwards under the 1961 Act and has been carried into the 2025 Act. It uses objective numeric triggers (under-reporting vs misreporting) and graded penalty rates (50% vs 200%). It also introduces an immunity provision under the Sec 270AA equivalent that the old regime lacked.

Is Sec 271(1)(c) of the 1961 Act still alive for anything?

Only for pending proceedings relating to assessment years up to AY 2016-17 under the 1961 Act. Any fresh penalty proceeding initiated for any tax year assessed under the 2025 Act is governed exclusively by the Sec 270A equivalent. Practitioners should note that post-1-April-2026, every new penalty notice will cite the 2025 Act provisions, not the old section numbers.

What is the immunity provision under the Sec 270AA equivalent?

Under the Sec 270AA equivalent, a taxpayer can apply for immunity from penalty and prosecution by paying the tax and interest on the under-reported addition within the time allowed in the demand notice and not filing any appeal against the assessment. The application must be made within one month from the end of the month in which the assessment order is received. Immunity is not available for misreporting cases or for additions exceeding the limit prescribed for immunity.

Is penalty mandatory in every case of addition?

No. The Sec 270A equivalent specifies exclusions where no penalty is levied: (a) bona fide difference of opinion supported by disclosure of all material facts, (b) genuine estimation difference accepted on appeal, (c) additions based on judicial interpretation where the taxpayer’s position was reasonable, and (d) additions that are reversed on appeal. The Assessing Officer’s discretion is structured by these safe harbours.

What are typical examples of under-reporting?

Common examples include: failure to include interest income reported in Form 26AS, omission of capital gain on a property sale reflected in AIS, claim of deduction under the Sec 80C equivalent without supporting documents, wrong deduction of home loan interest under the Sec 24(b) equivalent, and incorrect computation of house property income. These are numeric errors typically caught during scrutiny. Penalty is 50% of the tax on the addition.

What are typical examples of misreporting?

Examples include: inflated purchases from shell entities, fabricated rent receipts for HRA, bogus donation claims under Sec 80G equivalent, undisclosed cash deposits, fictitious business expenses, sham loans from non-existent parties, and fabricated long-term capital gain via penny-stock route. These involve active concealment or false documentation. Penalty is 200% of the tax on the addition and no immunity is available.

How does the 270A penalty interact with reassessment under the Sec 148 equivalent?

In reassessment cases, the under-reported amount is computed with reference to the last assessed income, not the originally returned income. If the reassessment results in further additions, the penalty under the Sec 270A equivalent is levied on the difference between the reassessed income and the previously assessed income. Misreporting penalty of 200% may apply if the reopening was based on incriminating material showing active concealment.

Can the penalty be reduced or waived?

Reduction is not automatic but available in limited circumstances — typically through the immunity application under the Sec 270AA equivalent for under-reporting cases, or through appellate decisions that re-characterise misreporting as under-reporting. Waiver of penalty under the Sec 273A equivalent is available in hardship cases where the taxpayer has voluntarily disclosed and cooperated. Appeal is the principal route for reduction.

What is the time limit for passing a penalty order?

Penalty order must be passed within six months from the end of the tax year in which the penalty proceedings were initiated, or within one year from the end of the tax year in which the appellate order is received, whichever is later. An order passed beyond limitation is void. The taxpayer should always check the dates on the penalty order against this limitation.

Can a penalty order be appealed independently?

Yes. A penalty order is appealable to the CIT(A) within 30 days under Chapter XVIII of the Income-tax Act, 2025. A further appeal lies to the ITAT within 60 days. Even if the quantum addition is confirmed by the appellate authority, the penalty can be challenged separately on grounds that the default is not under-reporting or misreporting as statutorily defined, or that the safe harbours apply.

Does the 2025 Act retain any old Sec 271 penalties?

Yes — but not Sec 271(1)(c). The 2025 Act retains equivalents of Sec 271A (failure to maintain books), Sec 271B (failure to get accounts audited), Sec 271C (failure to deduct TDS), Sec 271D/271E (acceptance/repayment of loan in cash), Sec 271F (failure to file return, now integrated into late filing fees), and Sec 271H (TDS statement defaults). These are procedural-default penalties distinct from the income-related Sec 270A penalty.
