Treatment of agricultural produce in business accounts: market value or sale receipts must be deducted from taxable business profits. Rule 7 requires that where a cultivator or receiver of rent in kind uses agricultural produce as raw material in a business, the market value of that produce, or sale receipts if included in business accounts, must be deducted in computing taxable business profits, and no further deduction is permissible for expenditure incurred as cultivator or receiver of rent in kind.
