Turnover estimation and single point levy principles upheld where the assessee lacked reliable contrary material.

An estimated 10% wastage allowance in turnover computation was upheld because the assessee produced no reliable material to justify a higher estimate, and the record showed the appellate authority had intended and applied that figure. The assessee's proposed formula for allocating outside-State purchases to inter-State sales was rejected as vague and unsupported by books or specific data, leaving the authorities free to adopt a reasonable method based on available material. The plea that goods already subjected to Central Sales Tax could not be taxed again under local sales tax law also failed, as single point levy operates within each State and there was no factual foundation for the alleged prior tax payment.

Issues: (i) whether the allowance of 10% wastage in the estimation of turnover was liable to be interfered with; (ii) whether the authorities were bound to apply the assessee's suggested formula for allocating outside-State purchases to inter-State sales; (iii) whether goods that had suffered Central Sales Tax could not again be brought to tax under the local sales tax law.

Issue (i): whether the allowance of 10% wastage in the estimation of turnover was liable to be interfered with.

Analysis: The assessee furnished no positive material, past records, or comparable instances to show that the wastage should be fixed at 15% to 20%, while the Revenue relied on an apparent clerical reference to 1%. On the record, the allowance of 10% wastage had in fact been intended and applied by the appellate authority, and there was no material to show that this estimate was unreasonable.

Conclusion: The 10% wastage allowance was upheld and the objection was rejected.

Issue (ii): whether the authorities were bound to apply the assessee's suggested formula for allocating outside-State purchases to inter-State sales.

Analysis: The request for application of a formula was vague and unsupported by books, records, or specific data showing the extent of local sales. In the absence of reliable material from the assessee, the authorities were entitled to adopt a reasonable method based on the available positive materials for estimating the taxable turnover.

Conclusion: The assessee's suggested formula was rejected.

Issue (iii): whether goods that had suffered Central Sales Tax could not again be brought to tax under the local sales tax law.

Analysis: No factual foundation was laid to show the extent of any tax already paid, and the plea that single point taxation operates throughout India was held to be legally untenable. Single point levy operates within each State, and taxation under the local law was not barred merely because the goods may have suffered tax under a different State regime.

Conclusion: The plea against local taxation was rejected.

Final Conclusion: The estimates and legal objections raised by the assessee failed, and the assessments and enhancement petitions were not disturbed.

Ratio Decidendi: In the absence of reliable contrary material, an estimated allowance made by the assessing authority or appellate authority will not be interfered with, and the doctrine of single point levy operates within the territorial limits of each State.
