When a Complainant Fails to Disclose the Loan Transaction and the Cheque Amount in Income Tax Returns

A recurring defence in cheque dishonour prosecutions under the Negotiable Instruments Act, 1881 is this: the complainant never mentioned the underlying transaction in his income tax returns, and the cheque amount finds no place in those returns. Accused routinely argue that an undisclosed, unaccounted loan cannot be a legally enforceable debt and that such omission demolishes the complainant's case. Does this argument succeed? The answer, generally, is no — at least not automatically.

The Starting Point: The Section 139 Presumption

Once a cheque's signature is admitted, Section 139 of the NI Act raises a presumption that the cheque was issued in discharge of a legally enforceable debt or liability. The Supreme Court in Rangappa v. Sri Mohan, (2010) 11 SCC 441 clarified that this presumption includes the existence of a legally enforceable debt, correcting the earlier narrower reading in Krishna Janardhan Bhat 2025 0 Supreme(Ker) 1998 and 2023 0 Supreme(Bom) 984.

Critically, however, this presumption is rebuttable. The accused does not need to prove the negative beyond reasonable doubt; it is enough to raise a probable defence that creates doubt about the existence or legality of the debt. If that threshold is crossed, the burden shifts back to the complainant to prove the debt on credible evidence.

Where Non-Disclosure in Income Tax Returns Fits In

The omission of the transaction from the complainant's income tax returns is a relevant — but not conclusive — factor:

• Courts have consistently held that a transaction not reflected in the returns does not by itself make the debt unenforceable; it is one circumstance among many in assessing whether the transaction is believable 2023 0 Supreme(Bom) 984.
• In cases involving hand loans between individuals, non-disclosure may raise suspicion without destroying the case. But where large sums are involved, courts expect more: proof of financial capacity, source of funds, mode and date of payment.
• Several acquittals illustrate the other side of the line. Where complainants admitted in cross-examination that substantial amounts were never shown in their returns, and could not otherwise prove financial capacity, courts held that the presumption stood rebutted and the complainant had failed to prove a pre-existing legally enforceable debt 2022 0 Supreme(Telangana) 638 and 2021 0 Supreme(Mad) 1520 and 2022 0 Supreme(Telangana) 177. One court observed that a liability to repay an unaccounted loan admittedly not disclosed in income tax returns cannot be treated as a legally recoverable debt in the absence of other proof 2021 0 Supreme(Mad) 1520.
• Conversely, when payment was made through banking channels or the transaction was otherwise established by credible evidence, courts have refused to discharge the accused merely because of a tax-return omission, noting there is no provision of the Income Tax Act that makes an unaccounted amount irrecoverable 2019 0 Supreme(P&H) 1446 and 2023 0 Supreme(Jhk) 1588.

The practical takeaway: the omission is ammunition for the accused, not a self-operating acquittal.

The Section 269SS Overlay for Cash Transactions

A related and frequently pleaded defence is violation of Section 269SS of the Income Tax Act, which prohibits accepting loans in cash of ₹20,000 or more. Here the High Courts diverge:

• The Kerala High Court in P.C. Hari v. Shine Varghese took the view that a debt arising from a cash transaction above ₹20,000 in violation of Section 269SS cannot be treated as a legally enforceable debt for Section 138 purposes, reasoning that courts should not regularise illegal transactions 2025 0 Supreme(Ker) 1998.
• The Bombay High Court in Prakash Madhukarrao Desai (2023 KHC Online 3165) and the Supreme Court's reasoning in Rangappa treat a Section 269SS violation as attracting only a penalty under Section 271D — a civil, remedial liability — and not as rendering the underlying transaction void or unenforceable 2025 0 Supreme(Ker) 1998.

The majority position, therefore, is that tax-law irregularity invites penalty proceedings but does not, standing alone, defeat a Section 138 claim.

How Courts Actually Weigh These Defences

In practice, the outcome turns on the totality of evidence:

1. Small amounts, credible oral evidence — non-disclosure in returns rarely proves fatal; the presumption under Sections 118 and 139 continues to operate 2023 0 Supreme(Bom) 1686.
2. Large amounts with no documentation — where the complainant cannot show source of funds, financial capacity, or any contemporaneous record, and admits non-disclosure, acquittals are common 2022 0 Supreme(Telangana) 177

   R. Narender VS Yakamma Keloth or Kalyan

   .
3. Bank-channel payments — when the loan was paid by cheque or draft, the absence of the entry in tax returns carries even less weight 2019 0 Supreme(P&H) 1446.
4. Suspicious conduct — courts also look at whether cheques were signed blank, whether serial numbers were consistent, and whether complainants attempted to give a criminal colour to what is essentially a civil dispute 2022 0 Supreme(Kar) 447 and 2022 0 Supreme(Kar) 989.

Key Takeaways

• Non-disclosure of the transaction and cheque amount in income tax returns is a relevant defence tool but does not automatically void the debt under Section 138 2025 0 Supreme(Ker) 1998.
• The accused must actively rebut the Section 139 presumption by raising a probable defence; mere suggestions are insufficient.
• A Section 269SS violation typically attracts only a Section 271D penalty and does not, per the dominant judicial view, make the debt unenforceable, though the Kerala High Court's view in P.C. Hari remains an exception within that jurisdiction.
• Complainants should document loans properly and reflect them in returns; accused should probe financial capacity, source of funds, and cross-examine on tax disclosures.
