Canal construction under turnkey EPC contracts for irrigation projects falls outside taxable works contract service on merits.

Construction of canals under a turnkey/EPC contract for Government irrigation or drinking-water projects was treated as falling outside taxable Works Contract Service because the activity was for non-commercial, non-industrial purposes and the binding larger-bench classification excluded such canal work from service tax under the relevant Finance Act provision. The exemption notification for canal construction was held prospective only and not retrospectively applicable, but that did not affect liability once the activity itself was found non-taxable on merits. As a result, the service tax demand, penalty, and related consequences were set aside.

Issues: (i) Whether construction of canals under a turnkey/EPC contract for Government irrigation projects falls within Works Contract Service; and (ii) whether Notification No. 41/2009-ST dated 23.10.2009 could be applied to the disputed period.

Issue (i): Whether construction of canals under a turnkey/EPC contract for Government irrigation projects falls within Works Contract Service.

Analysis: The contract was for construction of canals linked with reservoirs and dams for irrigation or drinking water purposes, awarded by the Government and undertaken for a non-commercial objective. The governing larger-bench ruling had held that construction of canals for irrigation or water supply, even when executed as a turnkey/EPC contract, falls within the exclusionary treatment in Section 65(105)(zzzza) of the Finance Act, 1994 and is not exigible to service tax when the work is for non-commercial, non-industrial purposes. Applying that binding classification principle, the activity could not be treated as taxable Works Contract Service.

Conclusion: The activity was not classifiable under Works Contract Service and the demand could not be sustained.

Issue (ii): Whether Notification No. 41/2009-ST dated 23.10.2009 could be applied to the disputed period.

Analysis: The notification granting exemption for canal construction was held to be prospective and not retrospectively applicable. However, once the activity itself was found to fall outside the taxable category, the question of exemption under the notification ceased to affect the liability.

Conclusion: The notification was not retrospectively applicable, but that did not alter the result because taxability itself failed.

Final Conclusion: The demand, penalty, and related tax consequences were set aside because the canal construction activity was excluded from the taxable category on merits.

Ratio Decidendi: Construction of canals for irrigation or water supply under a turnkey/EPC contract for Government projects, when undertaken for non-commercial and non-industrial purposes, is excluded from Works Contract Service under Section 65(105)(zzzza) of the Finance Act, 1994.
