Deduction on ST-1 forms and interest on assessed tax under the Delhi Sales Tax Act were limited by statutory conditions.

Deduction for sales against ST-1 forms depended on satisfaction of the statutory condition that the purchasing dealer be registered for the goods sold, and that condition failed where the dealer was not registered for electronic goods; the deduction was therefore disallowed. By contrast, a selling dealer was not guilty of wilful omission merely because it relied on ST-1 declarations honestly believed to be valid, as mere negligence or failure to detect a registration defect was insufficient. Interest under section 27 was confined to tax shown as due in the return and did not run from the date of filing on tax first brought to tax on assessment; interest on assessed tax arose only within the statutory framework. The assessee obtained partial relief.

Issues: (i) Whether the selling dealer was guilty of willful omission in claiming deduction on the strength of ST-1 forms furnished by the purchasing dealer; (ii) Whether sales against ST-1 forms issued by a purchasing dealer not registered for the goods sold were deductible from taxable turnover under section 4(2)(a)(v) of the Delhi Sales Tax Act, 1975; (iii) Whether interest under section 27 of the Delhi Sales Tax Act, 1975 was leviable from the date of submission of the return on tax assessed under section 23.

Issue (i): Whether the selling dealer was guilty of willful omission in claiming deduction on the strength of ST-1 forms furnished by the purchasing dealer.

Analysis: The statutory scheme required the purchasing dealer to obtain and furnish Form ST-1, and the forms were issued under a regulatory mechanism designed to be relied upon in ordinary course. The record did not show that the selling dealer knew the declarations were false. The expression "willful omission" could not be stretched to cover a return filed on the basis of a declaration honestly believed to be valid. Mere negligence or a failure to discover the purchasing dealer's defect in registration for the goods was insufficient to establish wilful omission.

Conclusion: The issue was answered in the negative and in favour of the assessee.

Issue (ii): Whether sales against ST-1 forms issued by a purchasing dealer not registered for the goods sold were deductible from taxable turnover under section 4(2)(a)(v) of the Delhi Sales Tax Act, 1975.

Analysis: Deduction under section 4(2)(a)(v)(B) depended on the sale being to a registered dealer in respect of goods specified in that dealer's registration certificate. That condition was not satisfied because the purchasing dealer was not registered for electronic goods. The selling dealer could rely on the form only to the extent permitted by the statutory framework, but the absence of the requisite registration for the goods meant the substantive condition for deduction failed. Penalty provisions against the purchasing dealer did not substitute for the tax consequence flowing from non-fulfilment of the deduction condition.

Conclusion: The issue was answered in the affirmative against the assessee.

Issue (iii): Whether interest under section 27 of the Delhi Sales Tax Act, 1975 was leviable from the date of submission of the return on tax assessed under section 23.

Analysis: On the plain language of sections 21(3) and 27, "tax due" referred to the tax due according to the return filed, not the tax ultimately assessed later. Interest under section 27(1) therefore attached only to default in payment of tax shown as due in the return, while interest on assessed tax could arise only in the circumstances contemplated by section 27(2). The authorities and precedent relied upon confirmed that an assessee who had filed a bona fide return could not be charged interest from the date of filing merely because the assessment later enhanced the tax liability.

Conclusion: The issue was answered in the negative and in favour of the assessee.

Final Conclusion: The reference was answered partly for the revenue on the deduction issue, but the levy of interest from the date of return was set aside, giving the assessee partial relief.

Ratio Decidendi: Under the Delhi Sales Tax Act, 1975, the selling dealer's entitlement to deduction depends on satisfaction of the statutory conditions for sales to a registered dealer in respect of the specified goods, but interest under section 27(1) is confined to tax due according to the return and not to tax later assessed for the first time.
