Service tax scope for maintenance repair and erection service was confined to the pre-amendment taxable entries, excluding structures and non-contract work

Maintenance and repair service was taxable for the pre-16.06.2005 period only when rendered under a specific maintenance contract or agreement; the wider post-amendment wording did not apply retrospectively, and a composite work order could not be split without evidence of a distinct maintenance arrangement. The demand was therefore unsustainable. Fabrication and erection of structures at site was not covered by erection, commissioning or installation service for the relevant period, because the original taxable entry applied to plant, machinery or equipment, while inclusion of structures came later. The activity was treated as manufacture rather than taxable erection service, so that demand also failed.

Issues: (i) Whether the activities of maintenance and repair were taxable prior to 16.06.2005 in the absence of a specific maintenance or repair contract or agreement. (ii) Whether fabrication and erection of structures at site was taxable under erection, commissioning or installation service for the period in dispute.

Issue (i): Whether the activities of maintenance and repair were taxable prior to 16.06.2005 in the absence of a specific maintenance or repair contract or agreement.

Analysis: The relevant definition of maintenance or repair, as applicable for the period prior to 16.06.2005, covered service rendered under a maintenance contract or agreement. The later amendment expanded the scope to services provided under any contract or agreement, but that wider formulation operated only from 16.06.2005. The Board circular also clarified that repair or servicing under a contract other than a maintenance contract or agreement was not covered earlier. On the facts, there was no separate maintenance or repair contract and the Revenue's attempt to split the composite work order by vivisection was not supported by the agreement or evidence showing a distinct maintenance arrangement.

Conclusion: The maintenance and repair demand for the earlier period was not sustainable. The finding is in favour of the assessee and against the Revenue.

Issue (ii): Whether fabrication and erection of structures at site was taxable under erection, commissioning or installation service for the period in dispute.

Analysis: The statutory definition, as it stood during the relevant period, covered erection, commissioning or installation of plant, machinery or equipment, while the later expansion to structures came into effect only from 01.05.2006. The Board circulars clarified that structures were not within the original scope and that erection referred to civil work connected with plant or machinery. The activity in question was fabrication of structures at site, which was treated as manufacture under the Central Excise tariff and Section 2(f) of the Central Excise Act, 1944, and was not shown to be civil erection of plant, machinery or equipment. Accordingly, the activity fell outside the taxable service for the period involved.

Conclusion: The demand under erection, commissioning or installation service was not sustainable for the period in dispute. The finding is in favour of the assessee and against the Revenue.

Final Conclusion: The demand on maintenance and repair service was set aside in favour of the assessee, and the demand on erection, commissioning or installation service was also set aside because the activity was held to be manufacturing activity outside the taxable service for the relevant period.

Ratio Decidendi: Prior to the statutory expansion of service tax coverage, maintenance or repair was taxable only when rendered under a specific maintenance contract or agreement, and fabrication of structures at site was not taxable as erection, commissioning or installation unless the provision expressly covered structures for the relevant period.
