Last reviewed: 10 September 2026. Cash deposit additions under Section 68 of the Income-tax Act remain one of the most heavily litigated fact-pattern disputes in Indian direct tax practice. What began as a concentrated wave of scrutiny around the November 2016 demonetisation window, when deposits of specified bank notes drew automatic verification, has now become a routine feature of assessments in the UPI and digital-reporting era — any unusually large cash deposit flagged through the Annual Information Statement (AIS) or Statement of Financial Transactions (SFT) can invite the same scrutiny, regardless of the year or the surrounding payment mode. Because the outcome turns almost entirely on the quality of contemporaneous evidence a taxpayer can produce, this remains an area where the line between an accepted explanation and a sustained addition is drawn in fine detail by the Income Tax Appellate Tribunal (ITAT) and the High Courts.
What Section 68 actually requires
Section 68 empowers the Assessing Officer (AO) to treat any sum credited in the books of an assessee for a given financial year as income of that year, where the assessee either offers no explanation about the nature and source of the credit, or the explanation offered is, in the AO’s opinion, not satisfactory. Over decades of litigation, this has settled into a three-limb test that courts apply consistently: the taxpayer must establish the identity of the creditor or source, the creditworthiness or capacity of that source to have provided the sum, and the genuineness of the underlying transaction. A bank passbook is not, strictly speaking, the assessee’s own book of account in the traditional sense, but most High Court decisions treat bank statements as “books” for Section 68 purposes — meaning an unexplained cash deposit into a bank account is squarely covered, not just an entry in a manually maintained ledger.
Why this dispute has intensified in the digital era
The revenue’s working position is straightforward: once a large, unexplained cash deposit is on record, the statutory presumption runs against the taxpayer, and the burden to displace that presumption with credible evidence lies on the assessee, not the AO. Historically this presumption was triggered in bulk during the demonetisation verification exercise; today it is triggered continuously, because most cash deposits above prescribed thresholds are captured through AIS and SFT reporting and flow automatically into risk-based scrutiny selection. That has widened the base of taxpayers facing Section 68 queries well beyond any single event.
The taxpayer’s counter-position is equally settled in principle, even if harder to establish in practice: where the source of a deposit is demonstrably genuine and corroborated by contemporaneous documents, an addition is not sustainable merely on suspicion, and a generic doubt cannot override specific, verifiable evidence. The dispute in almost every individual case is not about the legal test — identity, creditworthiness, genuineness — but about whether the taxpayer’s evidence actually clears that bar on the specific facts.
What the ITAT typically accepts and rejects
Illustrated by the substantial body of demonetisation-era orders that continues to inform current ITAT reasoning, the pattern of outcomes is fairly consistent:
| Explanation offered | Typical outcome |
|---|---|
| Agricultural income supported by land records (7/12 extract) and crop-sale evidence | Generally accepted as satisfactorily explained |
| Prior cash withdrawals from the same bank account, matched date-wise in a cash-flow reconciliation | Generally accepted, subject to the dates and amounts tallying |
| Genuine business cash sales matching GST/sales-tax returns, backed by a maintained cash book | Generally accepted |
| Gifts or loans from identifiable relatives who have their own PAN and return on record | Generally accepted, subject to the relative’s own creditworthiness being demonstrable |
| Generic claim of “past savings” with no supporting document | Typically added back |
| Unnamed “gifts from relatives,” with no confirmation or identity on record | Typically added back |
| Cash book prepared only after receipt of the notice | Typically rejected as an afterthought; addition often sustained, sometimes restricted to a residual figure where partial corroboration exists |
The recurring theme is corroboration at the time of the transaction, not a plausible story constructed after the fact.
A worked example
Consider an individual who deposited Rs 18,50,000 in cash across a single bank branch during FY 2025-26, flagged for verification through AIS. On examination: Rs 9,00,000 is traceable to the cash-in-hand declared as an opening balance in the preceding year’s balance sheet; a further Rs 4,50,000 is traceable to cash withdrawals made from the same account earlier in the year, matched date-wise against the bank statement. The remaining Rs 5,00,000 is explained only as “accumulated household savings over the years,” with no supporting record.
On these facts, the reasoning consistently applied by the ITAT would likely accept the Rs 13,50,000 (the opening balance plus the traceable withdrawals) as satisfactorily explained, since both limbs carry documentary corroboration. The balance Rs 5,00,000, however, is the kind of generic and uncorroborated explanation that is typically added back under Section 68. If sustained, such an addition would ordinarily be taxed at the special flat rate prescribed under Section 115BBE for unexplained cash credits — a materially higher effective rate than normal slab rates, and one that does not permit set-off of most deductions or losses against that specific income. The practical lesson is that even a strong partial explanation does not automatically protect the entire deposit; each rupee needs its own trail.
Common mistakes and red flags
- Explaining a deposit with an oral narrative and no supporting document at all
- Preparing a “cash book” only after receiving the notice, with no contemporaneous cash register behind it
- Citing “gifts from relatives” without naming the relative, the amount, the date, or their PAN
- Mixing personal and business cash without any reconciliation trail between the two
- Ignoring a mismatch between the cash-in-hand declared in the last balance sheet and the cash actually available to deposit
- Assuming a modest deposit will go unnoticed — AIS/SFT reporting increasingly aggregates deposits across accounts and branches, not just single large transactions
What should you do
For business owners, founders, and professionals who routinely handle cash, the practical defence is built well before any notice arrives:
- Maintain a running, dated cash book prospectively — not reconstructed retrospectively once a query lands
- Retain source documents at the time of each transaction: sale bills, gift deeds or written confirmations, loan confirmations bearing the lender’s PAN and return acknowledgment, and land records for agricultural income
- Reconcile cash deposits every quarter against the cash-in-hand already declared in your most recent balance sheet
- On receiving a Section 142(1)/143(2) notice or a fresh Section 148 notice referencing AIS-flagged cash deposits, respond with a fact-specific, document-backed explanation rather than a generic statement
- Where an addition is made despite partial corroboration, evaluate the Tribunal’s established logic on restricting additions to a reasonable residual amount, and consider a considered appeal rather than accepting the full addition unchallenged
Frequently asked questions
Are bank deposits covered under Section 68, even though a bank passbook isn't literally the taxpayer's own book of account?
Yes. Most High Court decisions treat bank statements as “books” for Section 68 purposes, so unexplained bank credits, including cash deposits, can be added as income if not satisfactorily explained.
Does Section 68 apply only to demonetisation-period deposits?
No. The demonetisation window in November 2016 generated the largest historical wave of such additions, but the same principle applies to any unexplained cash deposit in any year, now increasingly flagged through AIS and SFT reporting rather than a one-time verification drive.
What evidence do courts typically accept as a satisfactory explanation?
Corroborated sources such as agricultural income supported by land records and crop-sale evidence, prior cash withdrawals from the same bank account reflected in a cash-flow reconciliation, business cash sales matching GST or sales-tax returns with a maintained cash book, or loans and gifts from identifiable relatives who have their own PAN and return on record.
Will the entire deposit be added if only part of it is explained?
Not necessarily. Where partial corroboration exists, the Tribunal has in several cases restricted the addition to a reasonable residual amount rather than sustaining the full deposit as income, though this depends heavily on the specific facts and evidence on record.
Can I prepare a cash book now to explain an old deposit?
A cash book prepared only after receiving a notice, with no contemporaneous support, is typically viewed with suspicion and rarely accepted on its own. The safer course is to maintain a running cash book prospectively and retain source documents at the time of each transaction.
What is the tax impact if an addition under Section 68 is sustained?
Unexplained cash credits sustained under Section 68 are generally taxed at the special flat rate prescribed under Section 115BBE, which is significantly higher than normal slab rates and does not allow set-off of most deductions or losses against that income — making it important to build the documentary trail before the addition is made, not after.
