Faceless assessment, AIS/Form 26AS pre-fill, and third-party data matching have made fake exemptions, bogus expense bills and quiet under-reporting far easier to detect than most taxpayers assume. Under the Income Tax Act, 2025 — as amended by the Finance Act, 2026 — a genuine mistake still draws a 50% penalty on the tax avoided under Section 439. A deliberate one — a false rent receipt, a purchase bill from a supplier who does not exist, a donation to a cancelled trust — is misreporting, and the penalty jumps to 200% of the tax. Fake entries in the books attract a separate, harsher penalty under Section 444 equal to 100% of the bogus amount itself — on top of the tax and the Section 439 penalty. The Finance Act, 2026 also brought two significant changes practitioners must apply from Tax Year 2026-27 onward: the flat rate on unexplained income under Section 195 has been cut from 60% to 30%, and immunity under Section 440 has been widened to cover misreporting cases (including unexplained income) on payment of additional tax — not just plain under-reporting as under the law's original, unamended form. In the worst cases, it still becomes a criminal prosecution, now restructured under Section 478 with simple imprisonment on a tiered, amount-linked scale rather than the older mandatory rigorous imprisonment.
1. Introduction
Most clients who inflate a deduction or manufacture an expense bill do not think of themselves as tax evaders. A landlord who never actually paid rent to his father to justify an HRA claim, a small trader who buys a "purchase bill" from a broker to shore up his GP ratio, a professional who claims a family member's salary that was never really paid — in each case, the person filing the return usually believes the risk is limited to the tax saved, and that the worst outcome is being asked to pay it back with some interest.
That belief has become considerably more dangerous. The tax administration's pre-fill and matching architecture — AIS, Form 26AS, SFT reporting, GST-return cross-verification, and bank data-sharing — means that a fabricated claim is now more likely to be flagged automatically than by an officer's judgement call. Once flagged, the consequence is no longer just "tax plus interest." It is a penalty calculated as a multiple of the tax, potentially a second penalty calculated on the fabricated amount itself, and in serious cases, a criminal prosecution carrying a jail term.
This note sets out, in practitioner terms, exactly how the Income Tax Act, 2025 draws the line between an honest error and a punishable default, what each category of default costs, and where advisory attention should be concentrated when a client's return contains a claim that will not survive scrutiny.
2. Fake Exemption, Bogus Expense, Under-Reporting, Misreporting — What Each Term Actually Means
These four terms get used loosely in everyday conversation, but the Act treats them very differently, and the difference decides whether the penalty is 50% or 200% of the tax.
2.1 Under-Reporting — the Broader, Default Category
A person is treated as having under-reported income in situations that are largely mechanical and do not by themselves imply intent: the income finally assessed is higher than what was returned; no return was filed at all despite income exceeding the basic exemption limit; a reassessment results in a higher figure than the earlier assessment; or a returned loss is reduced or converted into positive income on assessment. Under-reporting, on its own, is the baseline default and draws a penalty of 50% of the tax payable on the under-reported amount.
2.2 Misreporting — the Aggravated Category That Covers Fake Claims
Misreporting is a subset of under-reporting reserved for cases involving deliberate misstatement. It specifically covers: misrepresentation or suppression of facts; failure to record an investment in the books of account; a claim of expenditure that is not substantiated by any evidence; recording a false entry in the books; failure to record a receipt that has a bearing on total income; and failure to report an international transaction or a specified domestic transaction. A fake exemption — a rent receipt for rent never paid, a donation receipt from an entity with a cancelled 80G registration, an inflated home-loan interest certificate — falls squarely within "misrepresentation of facts." A bogus expense — a purchase bill with no corresponding delivery, a consultancy fee paid to a shell entity, personal expenditure booked as business expenditure — falls within "expenditure not substantiated by evidence." Both attract the steeper 200% penalty, not the 50% rate.
The difference between 50% and 200% is not the size of the addition — it is whether the addition can be explained as an honest interpretation or computational slip, or whether it involves a document, receipt or entry that was fabricated to support a claim. A client who mis-classified a capital receipt as exempt in good faith is in Tier I. A client who generated a rent receipt to claim HRA he never actually paid is in Tier II. Advisers should assess every disputed addition against this distinction before assuming a 50% exposure.
3. Section 439 — The Charging Provision for Under-Reporting and Misreporting
The Competent Authority may, during the course of any proceedings under the Act, impose a penalty on any person who has under-reported income, in addition to the tax payable. Where under-reporting is on account of misreporting, the penalty shall be two hundred per cent of the tax payable on the under-reported income; in any other case, the penalty shall be fifty per cent of such tax.
Section 439 replaces Section 270A of the 1961 Act and preserves its structure closely, including the computation mechanics for cases where a return has been filed, where none has been filed, and where the addition arises out of reassessment. Sub-section (4) further provides a formula — broadly, the difference between total income computed under the general provisions and under the deemed-income provisions, before and after the under-reported amount — for cases involving deemed income under Section 206.
| Sl. | Situation | Classification | Penalty Rate |
|---|---|---|---|
| 1 | Assessed income higher than returned income due to a bona fide difference of opinion (e.g., disallowance of a debatable deduction) | Under-reporting | 50% of tax |
| 2 | No return filed though income exceeds the basic exemption limit | Under-reporting | 50% of tax |
| 3 | Fake rent receipt, bogus donation receipt, or inflated interest certificate used to claim an exemption/deduction | Misreporting | 200% of tax |
| 4 | Purchase or expense bill for which no evidence of the underlying transaction exists | Misreporting | 200% of tax |
| 5 | Sale receipt, rental receipt or professional receipt kept out of the books entirely | Misreporting | 200% of tax |
| 6 | Foreign remittance received or investment made abroad, not reported as an international transaction | Misreporting | 200% of tax |
- Rent receipts for HRA where no corresponding rental income is disclosed by the landlord, especially where the "landlord" is a close relative
- Section 80C/80D/80G claims unsupported by a certificate that will actually reconcile with the payee's own filings
- Purchase bills from suppliers whose GST registration is cancelled, suspended, or was never active for the relevant period
- Salary or professional fee paid to family members with no corresponding TDS, bank trail, or evidence of service rendered
- Business expenditure that is, on the facts, personal in nature — vehicle running costs, foreign travel, household staff wages routed through the firm
- Agricultural income claimed as exempt without corresponding land records or a plausible yield-to-land-holding ratio
4. Section 444 — The Separate, Harsher Penalty for Fake Invoices and False Book Entries
Where the fabrication goes further — an actual false entry is made in the books, or a genuine entry is deliberately omitted to evade tax — Section 444 imposes a penalty that is independent of, and in addition to, the Section 439 penalty. This provision, carried forward from Section 271AAD of the 1961 Act, was introduced specifically to counter the fake-invoicing schemes that proliferated after the introduction of GST, where invoices were generated for goods or services that were never actually supplied, purely to inflate input claims or expenses.
Where it is found, during any proceeding under the Act, that the books of account of a person contain a false entry, or that a relevant entry has been omitted to evade tax liability, the Assessing Officer or appellate authority may impose a penalty equal to the aggregate amount of such false or omitted entry. An identical penalty may be imposed on any other person who causes, induces, or is otherwise instrumental in the making of that false entry or omission — including the issuer of a bogus invoice.
"False entry" is defined broadly to include a forged or falsified document; an invoice for goods or services that were never actually supplied or received; and an invoice issued in the name of a party that does not genuinely exist. This means the penalty exposure is not confined to the person who books the bogus expense — the accommodation-entry provider who issues the fake invoice in the first place faces an equal penalty under Section 444, calculated on the same amount, quite separately from whatever exposure arises for them under GST law.
Unlike Section 439, where the penalty is pegged to the tax on the addition, the Section 444 penalty is pegged to the full face value of the false or omitted entry — not to the tax saved. A ₹20 lakh bogus purchase bill attracts a Section 444 penalty of ₹20 lakh in its own right, entirely independent of the tax and the Section 439 penalty that also apply to the same transaction. In combination, the arithmetic on a fabricated entry routinely exceeds the value of the entry itself.
5. Unexplained Credits, Investments and Expenditure — Sections 102 to 106, and the Rate Cut under Section 195
A related but distinct trap arises where a fabricated claim is not just disallowed but is reclassified as unexplained income. Where a credit entry in the books, an investment, an asset, or an item of expenditure cannot be satisfactorily explained as to its nature and source, Sections 102 to 106 of the Act deem the corresponding amount to be income of that year — irrespective of whether it looks like a "genuine" business receipt on the face of the books.
Income falling under Sections 102 to 106 is not taxed at slab rates; it is taxed under the special charging mechanism in Section 195. As originally enacted, Section 195 set this rate at 60%, with a further 10% penalty layered on separately under Section 443. The Finance Act, 2026 has changed both halves of that structure, with effect from Tax Year 2026-27: the flat rate under Section 195 has been reduced from 60% to 30% (surcharge and cess continue to apply on top), and the standalone 10% penalty under Section 443 has been omitted altogether — such cases no longer attract a separate penalty section of their own. Instead, unexplained income under Sections 102–106 has been expressly folded into the definition of misreporting under Section 439(11), so it is now penalised through the same 200%-of-tax mechanism that applies to a fake exemption or a bogus expense bill, rather than through a bespoke penalty layer.
The rate cut from 60% to 30% is real relief on the tax itself, but it does not soften the consequence of being caught. Because unexplained income is now explicitly a misreporting category under Section 439(11), an addition under Sections 102–106 identified by the Assessing Officer still attracts the full 200% misreporting penalty on the (now lower) tax figure — and, as discussed in Section 7 below, the only route to a materially reduced outcome is now the Section 440 immunity mechanism, which for this category specifically requires payment of additional tax at 120%, not the general 100% rate.
| Section | Covers | Typical Trigger in Practice |
|---|---|---|
| Section 102 | Unexplained cash credits | Unsecured loan, gift, or share capital credited in the books with no verifiable identity, creditworthiness, or genuineness of the lender/donor |
| Section 103 | Unexplained investments | Property, securities, or other assets acquired that are not recorded in the books, or exceed the recorded cost |
| Section 104 | Unexplained money / assets | Cash, bullion, jewellery, or other valuable article found or possessed, with no satisfactory source |
| Section 105 | Unexplained expenditure | Expenditure incurred (e.g., a wedding, renovation) that is disproportionate to disclosed income and cannot be satisfactorily explained |
| Section 106 | Amount borrowed/repaid via hundi or otherwise other than through an account payee instrument | Cash loan transactions structured to avoid the banking trail |
6. When It Crosses Into Prosecution — Sections 478, 483 and 484
Every default discussed so far is, at heart, a civil penalty — payable in addition to tax, but not by itself a criminal matter. That changes once the conduct is characterised as a wilful attempt to evade tax, which the Act, like its predecessor, treats as an offence carrying imprisonment.
Sections 473 to 485 and 494 of the Act — the entire prosecution chapter — were amended by the Finance Act, 2026 as part of a stated decriminalisation exercise, effective 1 April 2026. Across the board, rigorous imprisonment has been replaced with simple imprisonment, mandatory minimum terms have been removed, maximum terms have generally been capped at two years (three years for a repeat offence, down from seven), and punishment is now graded by the quantum of tax involved rather than applied as a flat range. The figures below reflect the law as it stands after this amendment, not the un-amended 2025 text.
6.1 Section 478 — Wilful Attempt to Evade Tax
If a person wilfully attempts, in any manner, to evade any tax, penalty or interest chargeable or imposable, or under-reports income, he shall be punishable — with simple imprisonment for a term up to two years, or with fine, or with both, where the amount sought to be evaded or the tax on under-reported income exceeds fifty lakh rupees; or with simple imprisonment for a term up to six months, or with fine, or with both, where that amount exceeds ten lakh rupees but does not exceed fifty lakh rupees.
Where the amount sought to be evaded or the tax on under-reported income is ₹10,00,000 or less, the amended provision does not prescribe imprisonment at all — the consequence is limited to a fine. This is a meaningful shift from the un-amended position (rigorous imprisonment starting at three months, with a single ₹25,00,000 threshold separating the two bands), and practitioners should recalibrate client risk assessments accordingly: a large number of matters that would previously have carried real imprisonment exposure now carry a monetary-only consequence under Section 478, though the Section 439 and Section 444 penalties on the same facts are unaffected by this change.
Courts have consistently held that Section 478 (and its predecessor, Section 276C of the 1961 Act) requires proof of a genuinely deliberate act — an honest computational error or a bona fide difference of interpretation does not meet the threshold. But a fabricated rent receipt, a purchase bill from a non-existent supplier, or a fake donation certificate remains precisely the kind of positive, deliberate act that has supported prosecution in past cases, and the decriminalisation reforms narrow the punishment band without disturbing that underlying test of intent.
6.2 Section 483 and Section 484 — Falsification of Books and Abetment
Where a person wilfully falsifies books of account or documents to enable another person to evade tax, Section 483 (corresponding to the earlier Section 277A) provides for separate prosecution — relevant, for instance, to an accountant or intermediary who prepares a fabricated set of books at a client's instruction. As amended by the Finance Act, 2026, the punishment under Section 483 has moved from rigorous imprisonment of three months to two years plus fine, to simple imprisonment for a term up to two years and fine — the mandatory minimum term has been removed, but a fine now attaches in every case.
Section 484 (corresponding to the earlier Section 278) extends liability to abetment of a false return, account, or statement, capturing anyone who induces another person to make a false claim, not merely the person who ultimately signs the return. Section 484 has also been restructured onto the same tiered, amount-linked scale as Section 478: simple imprisonment up to two years, fine, or both, where the amount that would have been evaded exceeds ₹50,00,000; simple imprisonment up to six months, fine, or both, where that amount is between ₹10,00,000 and ₹50,00,000; and a fine-only consequence below ₹10,00,000.
7. Section 440 — The Immunity Route, Significantly Widened by the Finance Act, 2026
Not every case that reaches the penalty stage needs to be litigated to the end. Section 440 (corresponding to the earlier Section 270AA) allows a taxpayer who accepts an assessment or reassessment order to apply for immunity from the Section 439 penalty and from prosecution under Chapter XXII, provided the tax and interest demanded have been paid within the time specified in the notice of demand, and no appeal has been filed against the order. The application is made in Form 161, and the Assessing Officer must now dispose of it within three months from the end of the month of receipt (extended by the Finance Act, 2026 from the earlier one-month timeline).
Until the Finance Act, 2026, this route was available only for plain under-reporting — a client whose addition was classified as misreporting (which, as Section 2 of this note explains, covers most fake-exemption and bogus-expense cases) could not use Section 440 at all. That has now changed. Section 440 has been amended to extend immunity to misreporting cases as well, provided the taxpayer pays an additional income-tax — over and above the tax and interest already payable — calculated as:
| Nature of Misreporting | Additional Income-Tax Payable for Immunity (In Lieu of Penalty) |
|---|---|
| General misreporting — fake exemption, bogus expense bill, suppressed receipt, false book entry | 100% of the tax payable on the under-reported income |
| Misreporting arising from unexplained credit, investment, asset or expenditure (Sections 102–106) | 120% of the tax payable on the under-reported income |
No waiver or immunity shall be granted if any proceeding has been initiated under Chapter XXII.
This condition is decisive in practice. Once a prosecution complaint has actually been filed or proceedings under Chapter XXII have been initiated, the Section 440 route closes — immunity is only available if the taxpayer moves before matters reach that stage. An order accepting the application is final, and no appeal or revision lies against it once the immunity application itself has been accepted.
Even after the Finance Act, 2026 widening, Section 440 immunity is confined to the Section 439 penalty and to prosecution under Chapter XXII. It does not extend to the separate penalty for false entries under Section 444. A client who has issued or used fake invoices can now, in principle, use the immunity route to close out the Section 439 misreporting penalty and the related prosecution risk by paying the 100%/120% additional tax — but the Section 444 penalty, calculated on the full face value of the false entry itself, survives independently and is not covered by any Section 440 application.
The practical effect of the amendment is to give advisers a genuine settlement lever in misreporting cases for the first time — including, notably, unexplained-income cases under Sections 102–106, which previously had no comparable route at all. Whether it is worth exercising depends on the arithmetic: paying 100–120% additional tax to close out a 200% penalty and prosecution risk can be the better outcome where the underlying fabrication is not seriously disputable, but where a client has a genuine factual defence, litigating the addition may still be preferable to accepting it outright.
8. Practical Computation — What a Bogus Expense Bill Actually Costs
A proprietorship books a purchase bill of ₹15,00,000 from a supplier later found to have no genuine business activity — a classic accommodation-entry scenario. On scrutiny, the expense is disallowed, the entry is treated as false, and the case is escalated for prosecution consideration.
| Computation Step | Amount (₹) |
|---|---|
| Bogus purchase bill disallowed and added to income | 15,00,000 |
| Tax on addition @ 30% (top slab, illustrative) | 4,50,000 |
| Health & Education Cess @ 4% | 18,000 |
| Tax + cess on the addition | 4,68,000 |
| Section 439(10) misreporting penalty @ 200% of tax | 9,00,000 |
| Section 444 penalty — 100% of the false entry | 15,00,000 |
| Total tax, cess and penalty exposure if litigated and lost | 28,68,000 |
| As a multiple of the original bogus bill (₹15,00,000) | ≈ 1.91× |
| Alternative: Section 440 immunity route — tax + cess + 100% additional tax, in lieu of the 200% penalty | 9,36,000 |
The illustration deliberately excludes interest under the applicable provisions and any exposure the supplier separately faces under Section 444 as the issuer of the false invoice, or under GST law for the same transaction — both of which would add further cost and are unaffected by the client's own immunity application. The point for advisory purposes is twofold: first, on a fabricated entry litigated to a full penalty order, the combined civil exposure alone can approach or exceed twice the value of the bogus claim; second, the Section 440 immunity route introduced by the Finance Act, 2026 can materially improve that outcome on the Section 439 component specifically — provided the client moves before any Chapter XXII prosecution proceeding is initiated, and accepts that the separate Section 444 penalty on the false entry itself is not covered by the immunity application either way.
- Under-reporting (Section 439) draws a 50% penalty on the tax; misreporting — which covers fake exemptions and bogus expenses — draws 200%
- Fake invoices and false book entries attract a separate penalty under Section 444 equal to 100% of the entry's face value, on top of Section 439
- Both the person who books a fake entry and the person who issues it face the Section 444 penalty independently
- Unexplained credits, investments and expenditure (Sections 102–106) are taxed at a flat 30% under Section 195 (cut from 60% by the Finance Act, 2026), with no deductions or set-offs — but now expressly treated as misreporting under Section 439(11), so the 200% penalty still applies on detection; the standalone 10% penalty formerly under Section 443 has been omitted
- Prosecution under Section 478 was decriminalised in tiers by the Finance Act, 2026: fine only up to ₹10,00,000; simple imprisonment up to 6 months between ₹10,00,000–₹50,00,000; simple imprisonment up to 2 years above ₹50,00,000 — rigorous imprisonment and the old flat ₹25 lakh threshold no longer apply
- Section 440 immunity (Form 161) was widened by the Finance Act, 2026 to cover misreporting too — 100% additional tax (120% for unexplained-income cases) in lieu of the Section 439 penalty and Chapter XXII prosecution, but only if applied for before any prosecution proceeding is initiated; it still does not touch the Section 444 false-entry penalty
- The distinguishing question in every disputed addition is not the amount, but whether a document, receipt or entry was fabricated — that single fact moves the case from Tier I to Tier II or III
9. Final Practitioner Takeaway
The tax saved on a fake rent receipt or a bogus purchase bill is almost always a small fraction of what is ultimately at stake once the claim is identified. Between the disallowed amount, the tax, the misreporting penalty, and — where an actual false entry is involved — the separate Section 444 penalty, the arithmetic turns what looked like a modest saving into a liability that can exceed the original amount several times over, before prosecution risk is even factored in.
For advisory purposes, the discipline that matters most is upstream: reviewing exemption and deduction claims for documentary support before filing, not after a notice arrives, and being direct with clients about the difference between a defensible position and a fabricated one — because the Act itself treats that difference as the line between a 50% penalty and a 200% one, or between a penalty and a prosecution.
With AIS, SFT and GST-return matching now largely automated, the sharpest risk area is no longer whether a fabricated claim will be detected — it is how a client responds once a mismatch notice is received. A prompt, well-advised revised return or immunity application under Section 440 can materially change the outcome; silence or a weak explanation almost always converts a civil matter into a misreporting case, and sometimes into a prosecution referral.
