Service Tax Valuation: where VAT paid on a deemed portion under VAT rules, service tax limited to the remaining contract value.

Valuation of tyre-retreading works contracts must follow the valuation rules applicable to works contracts: where actual labour and service components are not ascertainable and the taxpayer has validly discharged VAT using the prescribed percentage method, that deemed portion is treated as subject to VAT and cannot be relitigated for service tax; service tax liability is therefore confined to the remaining portion. The analysis applies the statutory fiction of classification and the non-overlap principle between VAT and service tax, resulting in set-aside of a demand that sought to tax the same deemed portion already taxed under VAT.

Issues: Whether service tax valuation for tyre retreading works contracts should be determined under Rule 2A(i) of the Service Tax (Determination of Value) Rules, 2006 by deducting the value of goods (material) where labour and material components are ascertainable, or alternatively under Rule 2A(ii)(B) applying a deemed percentage (70%) where labour charges are not ascertainable, and whether service tax can be levied on the portion already subjected to VAT.

Analysis: The Court examined Rule 2A of the Service Tax (Determination of Value) Rules, 2006 and the corresponding provisions of the Tamil Nadu VAT Rules, 2007 that permit VAT payment either by deduction of actual labour charges when ascertainable or by adopting a prescribed percentage where labour charges are not ascertainable. The facts established that the appellant had adopted the percentage method for VAT and paid VAT on 70% of the contract value because actual labour charges were not ascertainable for VAT purposes. Applying the statutory fiction embodied in Article 366(29A) and the mutual exclusivity of VAT and service tax as recognized by higher courts, the Court held that the Service Tax Department cannot take an inconsistent contrary stance on the same set of facts and legal background. Precedents addressing the non-overlap of sales tax/VAT and service tax and the requirement to give effect to the statutory fiction were considered in concluding the applicable valuation treatment.

Conclusion: The valuation question is answered in favour of the appellant. Having paid VAT on 70% of the contract value under the TNVAT rules (percentage method), service tax can only be levied on the remaining 30% of the contract value; the impugned order confirming demand under Rule 2A(ii)(B) is set aside.

Final Conclusion: The appeal is allowed and the impugned Order-in-Original is set aside; the appellant is entitled to consequential relief as per law.

Ratio Decidendi: Where VAT has been validly discharged on a deemed percentage of the works contract value under state VAT rules because actual labour charges are not ascertainable, service tax cannot thereafter be levied on that same portion; service tax liability must be confined to the remaining portion of the contract value.
