To discourage cash-based business transactions and promote a verifiable banking trail, the Act disallows any expenditure incurred in respect of which payment (or aggregate payments to a single person in a single day) is made otherwise than by an account payee cheque, account payee bank draft, or specified electronic clearing mode, once the payment exceeds the prescribed threshold. Where the disallowance applies, the entire payment — not merely the amount exceeding the threshold — is generally disallowed as a business deduction, making this a comparatively severe consequence for what may often be a compliance oversight rather than any attempt at tax evasion.

Specific relief provisions exist for defined categories where cash dealings are commercially unavoidable or customary — payments to certain agricultural produce sellers, payments in villages or towns not served by banking facilities, and other prescribed exceptions — recognising that a blanket cash restriction would be impractical in every business context.

Relevant Case Laws

Attar Singh Gurmukh Singh v. ITO (1991) 191 ITR 667 (SC) — upheld the constitutional validity of the cash-payment disallowance provision, rejecting the argument that it unreasonably restricts the freedom to carry on business under Article 19(1)(g) of the Constitution, and held that the provision is a reasonable regulatory measure aimed at curbing the use of unaccounted or black money, falling well within the legislature's competence to regulate business transactions in the interest of the general public.

Frequently Asked Questions

Q. Does the disallowance apply to the full payment or only the amount above the threshold?

A. Generally, once a payment breaches the prescribed threshold in a mode other than the specified banking channels, the entire payment (not just the excess over the threshold) is disallowed as a business deduction.

Q. Does splitting a single large payment into smaller cash instalments avoid the disallowance?

A. No — the restriction typically applies to the aggregate of payments made to a single person in a single day, so splitting a payment into multiple smaller cash transactions on the same day to a single payee does not avoid the disallowance.

Q. Are there any exceptions where cash payments above the limit are still allowed?

A. Yes — specified categories such as payments to certain cultivators, growers or producers of agricultural produce, and payments made in areas not served by banking facilities, along with other prescribed circumstances, are excluded from the disallowance.

Q. Does this provision apply to capital expenditure as well as revenue expenditure?

A. The specific business-expenditure disallowance applies to revenue expenditure claimed as a deduction; cash payments for capital asset acquisition are addressed through a related but distinct provision restricting depreciation and cost recognition for cash-paid capital expenditure above the threshold.

Precautions to Be Taken

1.      Route all business payments above the prescribed threshold through account payee cheques, bank drafts, or specified electronic modes as a standing policy, rather than relying on exceptions or after-the-fact justification.

2.      Track aggregate same-day payments to a single payee across all invoices and transactions, not just individual invoice amounts, since the threshold is commonly tested on an aggregate, same-payee, same-day basis.

3.      Where cash payments are genuinely unavoidable (remote locations, specific agricultural transactions), document the specific exception being relied upon and retain evidence supporting eligibility for it.

4.      Educate accounts and procurement teams on this threshold specifically, since inadvertent cash payments by operational staff unaware of the tax consequence are a common, avoidable source of disallowance.

5.      For capital asset purchases, apply the same banking-channel discipline, since cash payment above the threshold for a capital asset affects the cost recognised for depreciation purposes going forward, not merely a one-year revenue deduction.
