Revenue Cannot Vivisect Indivisible Turnkey Contracts For Service Tax Without Express Statutory Authority: Supreme Court Upholds CESTAT Ruling

"A taxing statute admits of neither intendment nor equity. The existence, extent and incidence of a tax must be discernible from the language employed by the legislature, and no tax can be imposed by implication or by an expansive construction of the charging provision." Supreme Court of India, in a significant ruling, affirmed that service tax could not be levied on the installation and commissioning component of indivisible turnkey contracts for ATMs prior to the introduction of the "works contract service" entry in the Finance Act, 2007.

A bench comprising Justices Prashant Kumar Mishra and Shree Chandrashekhar held that in the absence of an express statutory mandate, the Revenue could not artificially vivisect composite contracts to impose service tax.

The respondent-assessee, M/s Diebold Systems Pvt. Ltd., was engaged in supplying, installing, and commissioning Automated Teller Machines (ATMs) to banks under turnkey contracts. The Revenue Department sought to levy service tax on 33% of the gross consideration received for the period between July 2003 and April 2006, classifying it under "commissioning or installation" services. The Customs, Excise and Service Tax Appellate Tribunal (CESTAT) had set aside the service tax demands, prompting the Revenue to appeal to the Supreme Court.

The primary questions before the Supreme Court were whether turnkey contracts for supply, installation, and commissioning of ATMs constituted indivisible composite contracts, incapable of being vivisected for service tax under the Finance Act, 1994, during the relevant period. The Court also examined if the CESTAT was justified in ruling that no part of the composite consideration could be taxed as "commissioning or installation."

Fiscal Laws Demand Explicit Statutory Authority

The Supreme Court underscored a fundamental principle of fiscal jurisprudence, stating that tax liability must flow from the charging statute itself. It emphasized that taxing statutes "admit of neither intendment nor equity," and no tax can be imposed by implication or through an expansive interpretation of the charging provisions.

Machinery Provisions Cannot Create Charge

The Court clarified that machinery or valuation provisions are intended to facilitate the computation of a tax already validly imposed, and they cannot, by themselves, create or enlarge the tax charge. It stressed that charging provisions and machinery provisions must be construed harmoniously, without the latter supplying what the former lacks.

Finance Act, 1994 Lacked Vivisection Authority

During the relevant period (July 2003 to April 2006), the Finance Act, 1994, levied service tax on "taxable services" as defined in Section 65(105). The Court found that the statute did not contain any express provision authorizing the dissection or vivisection of an indivisible composite turnkey contract to isolate and tax one of its constituent service elements.

Revenue Cannot Create Taxable Events by Attribution

The bench firmly stated that unless the charging provisions themselves contemplated such an exercise, the Revenue could not, by merely adopting a method of valuation or attributing a notional percentage of the total consideration, create a taxable event that the statute itself had not recognized.

Turnkey Contracts Were Indivisible

Upon examining the contractual terms, the Court agreed with CESTAT's finding that the contracts were indivisible turnkey contracts for the supply, installation, and commissioning of ATMs. It noted that the obligations were integral to delivering fully functional ATMs, and the consideration was composite, not separately earmarked for installation or commissioning.

Historical Context of Composite Contracts

The judgment delved into the jurisprudence of composite contracts, tracing it to the Constitution Bench decision in State of Madras vs. Gannon Dunkerley & Co. (Madras) Ltd., which established that indivisible works contracts were not pure contracts of sale. While Article 366(29A)(b) of the Constitution allowed states to tax the goods component as a deemed sale, it did not convert such contracts into separate ones.

No Corresponding Provision for Service Tax Pre-2007

Crucially, the Court highlighted that unlike the constitutional amendment empowering states to tax the deemed sale element, the Finance Act, 1994, during the period in question, had no corresponding provision authorizing the Revenue to segregate and tax the service element of an indivisible composite contract.

"Service Contracts Simpliciter" vs. Composite Contracts

The Court distinguished between contracts for taxable service simpliciter and indivisible composite contracts. It held that prior to 01.06.2007, the existing taxable entries under the Finance Act, 1994, contemplated only service contracts simpliciter, not indivisible composite contracts involving both goods and services.

Reliance on Larsen & Toubro Limited

The bench found its conclusion to be consistent with the authoritative pronouncement in Commissioner, Central Excise and Customs, Kerala vs. Larsen and Toubro Limited. That judgment unequivocally held that the Finance Act, 1994, before 01.06.2007, lacked both the charging provision and the machinery to levy and assess service tax on indivisible composite works contracts.

Subsequent Legislative Change Confirms Prior Gap

The Court noted that the introduction of a specific taxable entry for "works contract service" (Section 65(105)(zzzza)) with effect from 01.06.2007, along with an appropriate valuation mechanism, was a substantive legislative measure. This development, the Court stated, reinforced that the existing taxable entries were insufficient to encompass such contracts earlier.

No Statutory Basis for 33% Attribution

The Supreme Court also found no statutory foundation for the Revenue's arbitrary attribution of 33% of the gross contractual consideration as representing the value of "commissioning or installation." It reiterated that a fiscal liability cannot rest upon a notional or assumed apportionment unsupported by the charging enactment.

In light of these findings, the Supreme Court held that the CESTAT had committed no error in setting aside the service tax demands. It concluded that the Finance Act, 1994, during the period from July 2003 to April 2006, did not authorize the vivisection of indivisible turnkey contracts for the purpose of isolating and taxing the installation and commissioning component. Consequently, the Revenue's appeals were dismissed, upholding relief for the assessee.
