Can WhatsApp Chats, Excel Sheets and Seized Phones Alone Justify a Tax Addition?

Summary: Searches and tax investigations increasingly involve data extracted from mobile phones, laptops, pen drives, cloud accounts and other digital sources. However, the existence of a WhatsApp message, spreadsheet, digital printout or similar electronic record does not by itself establish that the transaction mentioned in it actually occurred or that the amount represents taxable income of the assessee. The evidentiary inquiry involves separate questions concerning admissibility, ownership or authorship of the material, and whether the record proves the underlying transaction. Under the Bharatiya Sakshya Adhiniyam, 2023, Section 63 governs proof of electronic records through the prescribed certificate requirements. Separately, search provisions and statutory presumptions concerning seized material may permit presumptions regarding ownership and correctness of documents found in a person’s possession or control. Such presumptions, however, are rebuttable and do not automatically establish that every amount appearing in the material constitutes the assessee’s income. The Supreme Court decisions in CBI v. V.C. Shukla and Common Cause v. Union of India emphasise the limited evidentiary value of unsupported entries and the importance of corroboration where liability is sought to be imposed on another person. P.R. Metrani v. CIT is relevant to the nature of the search presumption, while Ajay Gupta v. CIT illustrates the requirement of establishing a proper connection between seized material and the assessee. Accordingly, digital material can be important evidence, but its weight depends on context, authenticity, connection with the assessee and independent corroboration. Bank records, invoices, books of account, forensic material, witness evidence and the timing of the alleged transaction may determine whether a digital entry merely raises suspicion or supports a sustainable tax addition.bns

The Main Legal Issue

Officers seize a broker’s phone in a raid. 3.5 delivered, will settle the rest later,” one chat read. The assessee never signed any thing. The bank statements show a cheque for a smaller amount. Weeks later, a notice proposes adding an unexplained income of ₹3.5 crore.

Does the chat prove that cash changed hands?

Searches now routinely result in imaging of phones, laptops, pen drives and cloud accounts. Increasingly, assessments depend on what’s in those devices. The legal question is whether digital material can carry an addition on its own, or whether it only points the Department towards evidence it still has to find.

Three questions get mixed up in these disputes, and keeping them apart makes the analysis much clearer.

• Is the electronic record admissible? This is a question of form. Under Section 63 of the Bharatiya Sakshya Adhiniyam, 2023, an electronic record is generally proved through a certificate identifying the record and the device, describing how it was produced, and signed as the section requires.
• Does the record belong to the person being assessed? A phone seized from a third party says something about that third party first.
• Does the record prove the fact the Department wants to prove? A chat can show that two people discussed a payment. It does not show that the payment was made, received, or taxable in a particular year.

Most additions fail on the second and third questions, not the first.

Applicable Legal Framework

The search power. The Income-tax Act, 2025 came into force w.e.f. 1st April, 2026. Section 247 provides for search and seizure and extends the power to a person’s “virtual digital space” which covers email, cloud storage, social media accounts and similar digital locations. Authorised officers can therefore access devices and online accounts, not only physical premises.

The presumption. The 1961 Act contained a rebuttable presumption in Sections 132(4A) and 292C. Where books of account, documents, money, bullion, jewellery or valuables are found in a person’s possession or control during a search, it may be presumed that they belong to that person, that their contents are true, and that signatures and handwriting are genuine.The 2025 Act continues such a presumption under the heading “Presumption as to assets, books of account, etc.” and expressly includes virtual electronic assets within its scope.

Three limits on this presumption matter in practice.

• It is a presumption that “may” be drawn. It is not a mandate. The wording is discretionary, in the way Section 114 of the Evidence Act, 1872 is.
• It is rebuttable. An assessee can displace it with a plausible explanation backed by material.
• Tribunals have repeatedly noted that the presumption goes to the correctness of the document found. It does not extend to saying that the amount mentioned is the assessee’s income.

Admissibility. For electronic records, Section 63 of the BSA, 2023 replaces Section 65B of the Evidence Act, 1872. For entries in books of account, Section 34 of the Evidence Act, 1872 (replaced by the BSA, 2023, which keeps the underlying principle) is the relevant provision in the older case law discussed below.

Judicial Position

Entries Alone Are Not Enough

Entries alone are not enough. In CBI v. V.C. Shukla, (1998) 3 SCC 410, the Supreme Court dealt with the “Jain hawala” diaries. It held that entries in loose sheets and diaries are not “books of account” within Section 34 of the Evidence Act. Even where such entries are relevant, the Court held they are only corroborative and cannot by themselves fasten liability on a person.

Supreme Court Applied the Principle to Digital Material

The Court applied this to digital printouts. In Common Cause v. Union of India, decided on 11 January 2017 and reported at (2017) 394 ITR 220 (SC), the Court considered material seized from the Birla and Sahara groups, including random sheets, computer printouts, hard disks and pen drives. Following V.C. Shukla, it held that such material, not shown to be kept regularly in the course of business, lacked the reliability needed to justify an investigation against third persons. They deal with different issues of tax assessment, but the corroboration rationale is often cited in tax disputes.

Search Presumption Is Rebuttable

The presumption is rebuttable. In P.R. Metrani v. CIT, (2007) 1 SCC 789 (also reported at (2006) 287 ITR 209), the Supreme Court treated the Section 132(4A) presumption as rebuttable. It held that the presumption was not available for framing a regular assessment. Parliament responded by inserting Section 292C in the 1961 Act through the Finance Act, 2007, with retrospective effect from 1 October 1975, which extended the presumption to assessment proceedings. Anyone relying on Metrani should read it alongside that amendment.

High Courts Require a Link Between Seized Material and Assessee

High Courts require a link. In Ajay Gupta v. CIT, IT Appeal No. 357 of 2010 (Allahabad High Court, 13 November 2019), the High Court set aside a Tribunal order that had restored an addition on the strength of the presumption alone. The Tribunal had not recorded how the loose sheets found in the search were linked to the assessee, and the High Court said an addition could not stand on a presumption without corroborative evidence.

Recent Tribunal Approach

Recent Tribunal approach. On 28 September 2026, ITAT Mumbai deleted additions in a matter where the Department relied on a WhatsApp message and a broker’s statement to allege receipt of cash. As reported, the Tribunal found that the material did not establish receipt of the amount in the year under assessment. A Tribunal order is persuasive, not binding on other benches, it turns on its own facts, and it may be taken further in appeal. It is better read as an example of the principle of corroboration and not as a rule that chats never count.

Practical Examples

A Chat With No Delivery Trail

A chat with no delivery trail. The message says “sent 40, check.” There is no date of delivery, no recipient, no ledger entry and no bank movement. The Department has proved that a conversation took place. It has not proved a payment.

An Excel Sheet Found on a Pen Drive

An Excel sheet found on a pen drive. The file has no author, no creation history that ties it to the assessee, and no link to any invoice or bank entry. Under V.C. Shukla and Common Cause, an unsupported spreadsheet of this kind carries very little weight on its own. A tally maintained in the ordinary course of business, with matching vouchers, stands on a different footing.

A Phone Seized From a Third Party

A phone seized from a third party. The presumption attaches to items found in the possession or control of the person searched. Material found with someone else does not automatically carry a presumption against the assessee. The Department generally needs to connect the data to the assessee through independent material.

A Chat That Is Corroborated

A chat that is corroborated. The message mentions an amount and a date. The same date shows a cash withdrawal by the other party, a handwritten receipt exists, and a statement is supported by a cross-examined witness. Here the chat is a strong piece of a larger picture, and the assessee faces a much harder task.

Common Mistakes

Common Mistakes by Assessees

By assessees:

• Saying only that “the chat is fabricated” without any supporting material.
• Not asking for the forensic image, hash values and the full chat export, so that the context of a single message cannot be examined.
• Discarding or editing their own phone data after a notice arrives, which can turn a weak case into a damaging one.
• Ignoring the period in which a payment is alleged to have been received.

Common Mistakes by the Department

By the Department:

• Treating the presumption as proof that the amount is income.
• Relying on a printout without Section 63 compliance.
• Not testing the statement of a third party by giving the assessee an opportunity to cross-examine.

Practical Steps

• Ask for the full material. Request a copy of every seized item relied on, including the complete chat thread and the forensic report, not selected screenshots.
• Check the Section 63 certificate. Confirm that the certificate identifies the device and describes how the printout was produced.
• Separate authorship from meaning. Admit nothing about who sent a message until you know what the whole conversation says.
• Test the link. Ask what independent material connects the entry to the assessee, to the amount, and to the year.
• Rebut with records. Bank statements, invoices, books, and a consistent written explanation carry more weight than a bare denial.
• Seek cross-examination where a third party’s statement is the foundation of the addition.
• Preserve your own data. Take a forensic copy of your devices before anything is changed, so you can show context and timing later.

Conclusion

Electronic material has changed how tax cases are investigated, but the principle behind the Supreme Court’s older decisions still holds. A record shows that something was written, saved or sent. Whether money moved, to whom, and in which year are separate facts that need separate proof. Assessees who understand that distinction can examine seized data calmly, and Departments that respect it build additions that survive appeal.
