Rule 161 of Income explained: this guide covers what it means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.
Rule 161 of the Income-tax Rules, 2026 requires PAN to be quoted and authenticated for cash deposits or withdrawals aggregating Rs 20 lakh or more in a financial year, and for opening a current account or cash credit account, with no threshold for the account opening.
What rule 161 does
Rule 161 gives effect to section 262(9)(a) and replaces rule 114BB of the Income-tax Rules, 1962. It sits alongside rule 159 but does something more demanding: it requires not just quoting but authentication.
Rule 161(1) provides that every person shall, at the time of entering into a specified transaction, quote his PAN in the documents pertaining to it, and every person specified in column 3 who receives such a document shall ensure that the number has been duly quoted and authenticated.
The three transactions
| Sl. No. | Transaction | Threshold | Person who must ensure authentication |
|---|---|---|---|
| 1 | Cash deposit or deposits in one or more accounts of a person with a banking company, co-operative bank (including a bank or banking institution under section 51 of the Banking Regulation Act, 1949) or Post Office | Rs 20 lakh or more in a financial year | The banking company or co-operative bank; or the Post Master General under section 2(j) of the Indian Post Office Act, 1898 as it existed prior to its repeal, or the Regional Head under the Post Office Rules, 2024 framed under the Post Office Act, 2023 |
| 2 | Cash withdrawal or withdrawals from one or more accounts of a person with the same institutions | Rs 20 lakh or more in a financial year | Same as above |
| 3 | Opening a current account or cash credit account with the same institutions | No threshold | Same as above |
The Rs 20 lakh test applies to the aggregate across one or more accounts of the same person in the financial year — a customer cannot stay below the line by spreading cash across accounts at the same bank. Equally, deposits and withdrawals are separate entries: Rs 15 lakh deposited and Rs 15 lakh withdrawn crosses neither threshold, even though Rs 30 lakh of cash moved.
Entry 3 has no value column at all. Opening a current account or cash credit account always requires PAN, however small the opening balance.
Rule 161 and rule 159 compared
| Point | Rule 159 | Rule 161 |
|---|---|---|
| Cash deposit or withdrawal threshold | Rs 10 lakh in a financial year | Rs 20 lakh in a financial year |
| Obligation on the customer | Quote PAN | Quote PAN |
| Obligation on the institution | Verify and record | Ensure quoted and authenticated |
| Substitute where no PAN | Form No. 97 declaration in specified rows | No declaration route |
| Government exemption | Class exemptions in sub-rule (6) | Central Government, State Government, consular office |
The two rules therefore stack. A cash deposit of Rs 25 lakh in a year triggers both — rule 159 at the Rs 10 lakh level and rule 161 at the Rs 20 lakh level — and rule 161 adds the authentication requirement on top.
The critical practical difference is that rule 161 has no Form No. 97 route. Where rule 159 lets a person without a PAN file a declaration in specified rows, rule 161 does not. A person opening a current account must have a PAN.
The exemptions — rule 161(2), (3) and (4)
Sub-rule (2): rule 161(1) does not apply where the person carrying out the transaction is the Central Government, a State Government or a consular office.
Sub-rule (3): rule 161(1) does not apply where all three of the following hold:
- (a) the person carrying out the transaction at Sl. Nos. 1 to 3 is a non-resident (not being a company) or a foreign company;
- (b) the transaction is entered into with an IFSC banking unit; and
- (c) that person has no income chargeable to tax in India.
Sub-rule (4) provides that "IFSC banking unit" has the meaning assigned in rule 159(7)(a).
The IFSC relief is cumulative. A non-resident transacting with an ordinary domestic branch is not covered. Nor is a non-resident who transacts with an IFSC banking unit but has income chargeable to tax in India. Banks should build the test as a three-part check in onboarding, not a single "non-resident" flag.
Authentication — rule 161(5) and (6)
Sub-rule (5) requires the PAN of an individual to be submitted to the Principal Director General of Income-tax (Systems), the Director General of Income-tax (Systems), or a person authorised by them with the approval of the Board, for the purposes of authentication referred to in section 262.
Sub-rule (6) provides that the Principal Director General or Director General of Income-tax (Systems) shall lay down the formats and standards along with the procedure for authentication.
The distinction between rule 159 and rule 161 turns on this. Under rule 159 the institution verifies. Under rule 161 the institution must put the PAN through the departmental authentication process and satisfy itself of the response.
Worked example
A proprietor operates two savings accounts at the same bank. During financial year 2026-27 he deposits Rs 9 lakh in one and Rs 12 lakh in the other, and opens a current account for his business with an initial deposit of Rs 25,000.
- Cash deposits: aggregate Rs 21 lakh across accounts — rule 161 entry 1 applies, and the bank must ensure PAN is quoted and authenticated. Rule 159 Sl. No. 6 also applies at the Rs 10 lakh level.
- Current account: rule 161 entry 3 applies regardless of the Rs 25,000 balance, and there is no declaration alternative.
Compliance checklist for banks and post offices
- Aggregate cash deposits and withdrawals per customer across all accounts, testing each direction separately against Rs 20 lakh.
- Require PAN at every current account and cash credit account opening — no threshold, no declaration route.
- Put individual PANs through the section 262 authentication process specified by the Systems Directorate and retain the response.
- Apply the Government and consular exemption in rule 161(2) and the three-part IFSC test in rule 161(3).
- Remember that rule 159 obligations run in parallel at lower thresholds.
Common mistakes
- Testing the threshold account by account. Aggregation is per person.
- Netting deposits against withdrawals. They are separate entries.
- Accepting Form No. 97 for a current account opening. Rule 161 has no declaration route.
- Treating verification as authentication. Rule 161 requires the departmental process.
- Applying the IFSC relief on residential status alone.
