Under Section 40A(3), if you pay more than ₹10,000 to a single person in a single day for a business expense, and you pay it in cash instead of through cheque, bank draft or an electronic mode like UPI, NEFT, RTGS or IMPS, the whole expense is disallowed. Not taxed extra — simply not allowed, so your taxable profit goes up by that amount. For transporters (persons plying, hiring or leasing goods carriages), the limit is higher, at ₹35,000.
But the law is not blind to real life. Rule 6DD of the Income-tax Rules lists the exact circumstances in which a cash payment above the limit is still accepted and your deduction is protected. These are the situations below.
The rule in one line: cash above ₹10,000 is disallowed by default. It is allowed only if your payment falls squarely within one of the Rule 6DD situations — and you can prove it.
The full list of Rule 6DD exceptions
Rule 6DD contains clauses (a) to (l). Each one below is a situation where a cash payment over the limit does not attract disallowance.
Rule 6DD(a) — Payments to banks and specified institutions
Payment made to the Reserve Bank of India, any banking company, the State Bank of India and its subsidiaries, cooperative and land mortgage banks, LIC, and notified financial institutions such as UTI and IDBI, including a primary agricultural credit society or a primary co-operative agricultural and rural development bank.
Rule 6DD(b) — Payments to the Government in legal tender
Payment to the Central or State Government where, under the rules, the payment is required to be made in legal tender — for example certain taxes, duties, cess, penalties or registration charges.
Rule 6DD(c) — Payments routed through the banking system
Payment made by letter of credit, mail or telegraphic transfer, a bill of exchange payable only to a bank, book adjustment from one bank account to another, or through a debit card, credit card or electronic clearing system.
Rule 6DD(d) — Book adjustment against mutual dues
Payment settled by way of adjustment against a liability the payee owed you for goods you supplied or services you rendered — a genuine set-off of mutual dues instead of an actual cash movement.
Rule 6DD(e) — Purchases directly from farmers and primary producers
Payment for the purchase of agricultural or forest produce, produce of animal husbandry (including hides and skins), dairy or poultry farming, fish or fish products, or the produce of horticulture or apiculture, made directly to the cultivator, grower or producer. (Bought from the producer, not a trader.)
Rule 6DD(f) — Cottage industry goods made without power
Payment for products manufactured or processed without the aid of power in a cottage industry, made to the person who produced them.
Rule 6DD(g) — Areas with no banking facility
Payment made in a village or town which, on the date of payment, is not served by any bank, to a person who ordinarily resides in or carries on business in that place. (Keep evidence that no bank served the area on that date.)
Rule 6DD(h) — Terminal benefits up to ₹50,000
Payment of gratuity, retrenchment compensation or similar terminal benefits to an employee or their legal heir, where the total such payment does not exceed ₹50,000. (Ceiling: ₹50,000.)
Rule 6DD(i) — Salary to employees on remote or temporary posting
Payment of salary, after deducting TDS, to an employee temporarily posted for a continuous period of 15 days or more at a place other than their normal place of duty or on a ship, where the employee does not maintain a bank account at that place.
Rule 6DD(j) — Payments on bank holidays or during a strike
Payment made on a day on which the banks were closed, whether on account of a holiday or a strike, and the payment could not be routed through banking channels that day.
Rule 6DD(k) — Payments made through an agent in cash
Payment made by any person to their agent who is required to make payment in cash for goods or services on behalf of that person.
Rule 6DD(l) — Foreign currency and money-changer transactions
Payment made by an authorised dealer or a money changer against the purchase of foreign currency or travellers' cheques in the normal course of their business.
The condition everyone forgets: you must be able to prove it
An exception protects you only if you can prove it. The burden of proof is on you, the payer, not on the department. For every cash payment above the limit that you claim under Rule 6DD, keep documentary evidence on file:
- The purchase bill and the producer's identity and address for agricultural or cottage-industry purchases.
- A certificate or credible evidence that no bank served the area on the date of payment.
- A record of the bank holiday or strike for that date.
- The agency arrangement in writing where an agent paid in cash on your behalf.
Without this, an otherwise valid exception can still be disallowed at assessment.
The trap most people miss: Section 40A(3A)
Section 40A(3) looks at cash paid in the same year. Its companion, Section 40A(3A), catches deferred payments. If you claimed an expense on an accrual basis in one year and later settle that liability in cash above ₹10,000 in a following year, the amount paid is treated as your income in the year of that cash payment. The effect over two years is the same as losing the deduction, so review any pending accrual liabilities before settling them in cash.
A word on genuine transactions: courts have observed that the purpose of Section 40A(3) is to curb unaccounted money, not to punish genuine business payments. Where a transaction is real, the payee is identified and cash was genuinely unavoidable, some rulings have relaxed the disallowance. Treat this as a supporting argument only — your first line of defence should always be to bring the payment within a Rule 6DD clause, backed by proof.
What to actually do
- Set a hard cash ceiling of ₹9,999. Configure your accounting or billing software to flag any cash payment above it before it is recorded.
- Default to digital. UPI, NEFT, RTGS, IMPS and account-payee cheques are all safe modes. A bearer or self cheque is not — it is treated like cash.
- Do not split payments. Breaking one bill into several sub-₹10,000 cash payments to the same person on the same day does not work; the amounts are aggregated and disallowed.
- Build the Rule 6DD file as you go. If you regularly buy from farmers or operate in areas without banking, collect the evidence at the time of payment, not at assessment.
Legal backing. This note is based on Section 40A(3) and Section 40A(3A) of the Income-tax Act, 1961, read with Rule 6DD of the Income-tax Rules, 1962. The ₹10,000 per person per day limit (₹35,000 for goods-carriage transporters) applies to revenue expenditure computed under “Profits and Gains of Business or Profession.” The Rule 6DD clauses (a) to (l) are stated in line with the Income Tax Department's official material on disallowance of cash expenses (incometaxindia.gov.in). Auditors report such payments under Clause 21(d) of Form 3CD.
Frequently asked questions
What is the cash payment limit under Section 40A(3)?
Under Section 40A(3), a business expense paid in cash above 10,000 rupees to a single person in a single day is disallowed as a deduction. For transporters plying, hiring or leasing goods carriages, the limit is higher at 35,000 rupees.
Can a cash payment above 10,000 rupees ever be claimed as a business expense?
Yes. If the payment falls within one of the exceptions in Rule 6DD of the Income-tax Rules, and you can prove it with documentary evidence, the deduction is protected even though it was paid in cash.
Is a cash payment to farmers allowed as a business expense?
Yes. Under Rule 6DD(e), payments for the purchase of agricultural, animal husbandry, dairy, poultry, fish, horticulture or apiculture produce made directly to the cultivator, grower or producer are allowed even in cash, provided you buy from the producer and not a trader.
Does splitting a payment into amounts below 10,000 rupees avoid disallowance?
No. Multiple cash payments to the same person on the same day are aggregated. If the total crosses the limit, the expense is disallowed, so splitting a bill does not help.
What is Section 40A(3A)?
Section 40A(3A) catches deferred payments. If you claimed an expense on an accrual basis in one year and later settle that liability in cash above the limit in a following year, the amount paid is treated as your income in the year of the cash payment.
Which payment modes are safe to avoid disallowance under Section 40A(3)?
Account-payee cheques and drafts, and electronic modes such as UPI, NEFT, RTGS, IMPS, debit or credit cards and electronic clearing are all safe. A bearer or self cheque is treated like cash and does not protect the deduction.
