Section 186 of the Income-tax Act, 2025 is the current general rule restricting large receipts through cash or other non-permitted modes. For finance teams, accountants and business owners, the key point is that the ₹2 lakh limit is not tested only invoice by invoice. The section contains three separate tests: receipts from one person in a day, receipts for a single transaction, and receipts relating to one event or occasion from a person. The Income-tax Act, 2025 came into force on 1 April 2026, and the current official text can be checked through the Income Tax Department’s Income-tax Act, 2025 navigator and the Act as amended by the Finance Act, 2026.
What Section 186 actually restricts
Section 186 says that no person shall receive ₹2,00,000 or more except through an account-payee cheque, an account-payee bank draft, an electronic clearing system through a bank account, or another electronic mode prescribed under the law. The restriction therefore focuses on the mode of receipt. It is not merely a bookkeeping disclosure rule and it is not limited to businesses; the statutory wording applies to a person unless an exception applies.
The three ₹2 lakh tests are independent
1. Aggregate receipts from one person in a day
The first test looks at the total received from one person during a single day. Splitting the amount into several receipts on the same day does not avoid the test if the aggregate reaches ₹2 lakh.
Example: A business receives ₹1,10,000 in the morning and ₹95,000 in the evening from the same customer on the same day through a non-permitted mode. The aggregate is ₹2,05,000, so the daily-person test must be considered even though neither individual receipt is ₹2 lakh.
2. Receipt in respect of a single transaction
The second test follows the transaction rather than the calendar day. A single transaction cannot be divided across different days merely to keep each individual receipt below ₹2 lakh.
Example: A customer purchases equipment under one transaction for ₹3,60,000. If the seller proposes to receive ₹1,80,000 on Monday and ₹1,80,000 on Friday through non-permitted modes, the fact that each instalment is below ₹2 lakh does not by itself remove the single-transaction test.
3. Transactions relating to one event or occasion from a person
The third test is wider than a single invoice. It requires the recipient to consider whether multiple transactions relate to one event or occasion involving the same person. This prevents a compliance review from stopping at invoice numbers when the commercial arrangement is really one event or occasion.
Example: If separate invoices are raised to the same customer for venue, catering and decoration connected with one event, the finance team should not assume that separate billing automatically keeps every receipt outside Section 186. The event-or-occasion test should be examined before accepting a non-permitted mode.
Do not confuse Section 186 with the loan and deposit rule
Section 186 itself excludes transactions of the nature referred to in Section 185. Section 185 is the separate current-law provision dealing with taking or accepting certain loans, deposits and specified sums, and it uses its own monetary tests. This distinction matters because applying the general ₹2 lakh rule to a transaction that belongs under Section 185 can produce the wrong compliance conclusion.
A practical classification sequence is: first identify the legal nature of the receipt; then decide whether Section 185 applies; if it does not, test Section 186; and only after that decide which receipt mode is permitted.
Who is expressly outside Section 186?
The statutory exceptions include receipts by the Government, a banking company, a post office savings bank and a co-operative bank. Section 186 also excludes transactions of the nature referred to in Section 185 and permits the Central Government to notify other persons, classes of persons or receipts. Because notification-based exceptions can change, a taxpayer relying on one should retain the specific current notification rather than rely on an old checklist.
What is the penalty exposure?
Section 451 provides that the Assessing Officer may impose a penalty equal to the sum received in contravention of Section 186. That makes the control important even where the underlying receipt is genuine and properly recorded in the books. The compliance problem is the prohibited mode of receipt, not necessarily concealment of the transaction.
There is also an important safeguard. Section 470 states that no penalty is to be imposed for failures covered by specified penalty provisions, including Section 451, if the person proves that there was reasonable cause for the failure. Reasonable cause should not be treated as a routine exemption. If an exceptional case arises, the facts and evidence supporting the cause should be documented contemporaneously.
Practical accounts-control checklist
- Classify the receipt before accepting it. Identify whether it is a sale receipt, service receipt, advance, reimbursement, loan, deposit or another category.
- Check the customer or counterparty total for the day. A receipt below ₹2 lakh may still breach the daily aggregate test when combined with earlier receipts from the same person.
- Link instalments to the underlying transaction. Do not test each instalment in isolation if they relate to one transaction.
- Tag event-based collections. Where multiple invoices relate to one event or occasion, keep a common reference so the aggregate can be reviewed.
- Use permitted banking or electronic modes before the threshold is crossed. Do not wait until year-end reconciliation to discover that receipt mode was wrong.
- Separate Section 185 cases. Loans, deposits and specified sums may require a different threshold analysis.
- Retain evidence. Keep invoices, agreements, receipt ledgers, bank records and any notification or exception relied upon.
Common mistakes to avoid
- Treating ₹2 lakh as a per-invoice threshold only.
- Splitting one transaction over several days and assuming the rule no longer applies.
- Ignoring multiple receipts from the same person on the same day.
- Failing to connect separate invoices relating to one event or occasion.
- Applying Section 186 to a transaction that actually falls under Section 185.
- Assuming that recording the receipt correctly in the books cures a prohibited payment mode.
Practical takeaway
The safest way to manage Section 186 is to build the control around the counterparty and the underlying commercial purpose, not only the individual receipt voucher. Before accepting a large receipt, test the same-person daily aggregate, the single-transaction total and the event-or-occasion connection. If any test reaches ₹2 lakh, use a permitted mode unless a statutory exception clearly applies, and preserve evidence of the decision.
