Court: Supreme Court of India
Bench: Justice Prashant Kumar Mishra and Justice Shree Chandrashekhar
Judgment Date: 6 August 2026
Case: Civil Appeal Nos. 4708–4711 of 2008
Citation: 2026 INSC 808
Case Overview
The Supreme Court considered whether service tax could be imposed on part of the consideration received by Diebold Systems Pvt. Ltd. under turnkey contracts with banks for supplying, installing and commissioning Automated Teller Machines (ATMs). The Revenue treated 33% of the composite consideration as payment for installation and commissioning and demanded service tax for the period July 2003 to April 2006. The Court examined the Finance Act, 1994 and the nature of the contracts. It held that the contracts were indivisible composite turnkey contracts and that, during the relevant period, the statute did not authorise the Revenue to split them and tax a notional service component.
Facts
Diebold Systems Pvt. Ltd. was engaged in supplying Automated Teller Machines to various banks. Under contracts entered into with the banks, the company was responsible not only for supplying the ATMs but also for their transportation, installation, testing and commissioning. The contracts were executed on a turnkey basis, with a single consolidated consideration for the entire work. There was no separate consideration for installation or commissioning.
The Revenue Department issued three show-cause notices covering the period from July 2003 to April 2006. It took the view that 33% of the gross consideration received by Diebold represented the value of installation and commissioning services. According to the Revenue, this component was taxable under the category of “commissioning or installation” under Section 65(105)(zzd) of the Finance Act, 1994. Service tax, interest and penalties were consequently demanded.

Diebold challenged the demands before the Customs, Excise and Service Tax Appellate Tribunal (CESTAT). The Tribunal examined the contractual terms and held that the contracts were indivisible turnkey contracts. Installation and commissioning were only incidental parts of the larger obligation to supply fully functional ATMs. Since there was no statutory authority during the relevant period to split such composite contracts, the CESTAT set aside the demands. The Revenue then appealed to the Supreme Court.
Court’s Observations/Reasoning
The Supreme Court first reiterated an important principle of fiscal law: a tax can be imposed only when there is clear authority in the charging statute. A machinery or valuation provision can determine the amount of an existing tax liability, but it cannot independently create or enlarge that liability.
The Court examined Sections 65, 66 and 67 of the Finance Act, 1994, as they stood during the relevant period. It found that although “commissioning or installation” was a taxable service, the legislation did not contain any provision permitting the Revenue to divide an indivisible composite turnkey contract and separately tax one component of it.
The Court found that Diebold’s contracts had one overall commercial objective—the delivery of fully functional ATMs. Supply, transportation, installation, testing and commissioning were all integral parts of achieving that objective. The consideration was also composite, and the contracts did not provide for separate payment for installation or commissioning.
The Court rejected the Revenue’s attempt to treat 33% of the consideration as the value of installation and commissioning. It held that the percentage had no statutory basis and that administrative estimation could not create a taxable event where the charging statute did not provide for one.

The Court also relied upon the principles laid down in State of Madras v. Gannon Dunkerley & Co. and Commissioner, Central Excise and Customs, Kerala v. Larsen and Toubro Ltd. It noted that Parliament subsequently introduced a specific taxable entry for works contract service with effect from 1 June 2007, along with a mechanism for determining the service component. This legislative development supported the conclusion that the earlier statutory framework did not permit such composite contracts to be artificially divided for service-tax purposes.
Decision
The Supreme Court agreed with the CESTAT and held that, for the period July 2003 to April 2006, the Finance Act, 1994 did not authorise the Revenue to artificially separate the installation and commissioning component from Diebold’s indivisible turnkey contracts.
The Court therefore held that service tax could not be imposed on the notional 33% component of the composite consideration. It found that the CESTAT had correctly set aside the service-tax demands. Accordingly, the Supreme Court dismissed all the appeals filed by the Revenue and affirmed the CESTAT’s order.
Conclusion
The judgment reinforces the fundamental principle that tax liability must flow from the statute itself. Revenue authorities cannot create a tax liability by artificially dividing a composite commercial transaction or by assigning a notional value to one part of the contract when the legislation does not provide for such segregation.
The decision is particularly significant in the field of indirect taxation because it distinguishes between a standalone taxable service and a composite contract involving both goods and services. It also demonstrates the importance of examining the statutory framework applicable during the relevant period rather than applying a later legislative mechanism retrospectively. The judgment ultimately confirms that the power to tax must be clearly traceable to legislative authority and cannot be supplied through administrative interpretation.
