Substantiation and export nexus govern deductions, while unsupported claims fail and unvouched ad hoc expense disallowances cannot stand.
Provision for doubtful debts unsupported by evidence or write-off is not an ascertained liability for book-profit computation under section 115JB, and unsubstantiated expenditure and unidentified unclaimed liabilities remain disallowable or taxable. An ad hoc expense disallowance is impermissible where business expenditure is accepted and books are not rejected. Software licence and maintenance costs require item-wise assessment of purpose, duration, recurrence and enduring benefit. Foreign-exchange hedging and marked-to-market gains require a direct export nexus for deduction under section 10A. Excess dividend distribution tax requires verification for refund, while employee stock-option discount is allowable business expenditure.
Issues: (i) Whether provision for doubtful debts could be excluded from book profit under section 115JB; (ii) Whether expenditure claims unsupported by details and vouchers were allowable; (iii) Whether an ad hoc disallowance could be made without rejection of books of account; (iv) Whether unidentified unclaimed liabilities were taxable under section 41(1); (v) Whether software licence and maintenance expenditure was capital or revenue in nature; (vi) Whether foreign-exchange gains from forward hedging contracts and marked-to-market gains qualified for deduction under section 10A; (vii) Whether excess dividend distribution tax paid in relation to non-resident shareholders required verification for refund; (viii) Whether discount on issue of employee stock options was allowable business expenditure.
Issue (i): Whether provision for doubtful debts could be excluded from book profit under section 115JB.
Analysis: The party-wise material tendered at the appellate stage was not supported by an application, affidavit, or contemporaneous evidence and could not be admitted after substantial delay. The provision was unsupported by reasons, underlying evidence, or write-off of the relevant balances and was therefore not an ascertained liability within Explanation 1(c) to section 115JB.
Conclusion: The provision for doubtful debts was not deductible in computing book profit under section 115JB, against the assessee.
Issue (ii): Whether expenditure claims unsupported by details and vouchers were allowable.
Analysis: The expenditure provisions were unsupported by particulars, evidence, or vouchers before the tax authorities. A deduction cannot be allowed where the claimant does not substantiate the expenditure with proper supporting material.
Conclusion: The disallowances of the unsupported expenditure claims were sustained, against the assessee.
Issue (iii): Whether an ad hoc disallowance could be made without rejection of books of account.
Analysis: Once expenditure had otherwise been accepted as business expenditure and the books of account had not been rejected, an ad hoc disallowance could not be sustained merely because individual items below a specified value lacked vouchers.
Conclusion: The ad hoc disallowance was deleted, in favour of the assessee.
Issue (iv): Whether unidentified unclaimed liabilities were taxable under section 41(1).
Analysis: Although no accounting entry recording cessation of liability had been passed, the assessee failed to furnish details identifying the creditors to whom the liabilities remained payable. In the absence of creditor particulars, no relief from the addition could be granted.
Conclusion: The addition relating to unclaimed liabilities was sustained, against the assessee.
Issue (v): Whether software licence and maintenance expenditure was capital or revenue in nature.
Analysis: The classification depends on the nature and purpose of the software, the duration of benefit, recurrence of the expenditure, and whether it results in a substantial upgrade, enduring advantage, or extension of useful life. Verification of each voucher and the books of account was necessary to apply these tests.
Conclusion: The issue was restored for item-wise verification and determination according to law.
Issue (vi): Whether foreign-exchange gains from forward hedging contracts and marked-to-market gains qualified for deduction under section 10A.
Analysis: Deduction under section 10A is confined to profits directly attributable to export activity. The gains from forward hedging contracts and marked-to-market differences lacked a demonstrated direct nexus with exports.
Conclusion: The hedging and marked-to-market gains were not eligible for deduction under section 10A, against the assessee.
Issue (vii): Whether excess dividend distribution tax paid in relation to non-resident shareholders required verification for refund.
Analysis: The issue had been decided in the assessee's favour in an earlier year. Verification was required to compute any excess dividend distribution tax paid and determine the consequential refund.
Conclusion: The matter was restored for verification and grant of refund of any excess dividend distribution tax in accordance with law, in favour of the assessee.
Issue (viii): Whether discount on issue of employee stock options was allowable business expenditure.
Analysis: The allowability of employee stock option discount as business expenditure was supported by binding and consistently followed appellate decisions, including decisions in the assessee's own subsequent years.
Conclusion: Discount on issue of employee stock options was allowable in computing business income, in favour of the assessee.
Final Conclusion: Unsupported claims and gains without a direct export nexus remained taxable, while the ad hoc expense disallowance and employee stock option deduction were resolved in the assessee's favour; software and dividend distribution tax claims require fresh verification.
Ratio Decidendi: A deduction or adjustment depends on substantiation and the statutory nexus required: unsupported liabilities and expenses cannot be allowed, whereas an ad hoc disallowance without rejection of books is impermissible, and only gains directly linked to exports qualify under section 10A.
