Accrual basis interest recognition: interest taxed on accrual must be included when computing capital gain from subsequent sale.
Where interest has been accounted as income on an accrual basis before the sale of a security, the amount already taxed as interest income on accrual basis shall be taken into account for computation of income arising from such sale.

Interest on compensation taxed as Income from Other Sources when received; accounting standard ICDS does not displace the statute.
Interest received on compensation or enhanced compensation is taxable in the year of receipt and must be reported under Income from Other Sources, regardless of whether the assessee uses mercantile or cash accounting; where ICDS IV conflicts with the Act the statute prevails.

ICDS applicability to gross-basis incomes confirms ICDS governs computation of taxable interest, royalty and fees for technical services.
ICDS IV (Revenue Recognition) applies to incomes taxed on a gross basis, including interest, royalty and fees for technical services payable to non-residents, and such receipts must be computed and recognized under ICDS principles for determining the amount chargeable to tax.

Accrual-based revenue recognition: interest and royalty must be recognised despite collection uncertainty; statutory provisions prevail.
Interest is recognised on a time basis and royalty according to contractual terms; later non recovery may be claimed as a deduction under the amended deduction provisions, and applicable statutory provisions prevail over ICDS IV.

Revenue recognition for leases: lease treated as income not sale; lessor taxed on rent and entitled to depreciation.
ICDS IV recognises revenue when risk and rewards transfer, so leases are not sales: lease rent is taxable income and the lessor may claim depreciation. Under hire purchase, both parties cannot claim depreciation on the same asset; substance-over-form principles indicate the owner giving the asset on hire should recognise sale while the hirer is entitled to depreciation.

Revenue recognition under ICDS IV applies to real estate developers and BOT operators absent a specific exclusion.
In the absence of any specific ICDS notified for real estate developers, BOT projects and leases, the relevant provisions of the Income tax Act and applicable ICDS (including ICDS III and ICDS IV) apply to revenue recognition, income computation and disclosure for those transactions.
