CESTAT Bangalore Quashes Differential Service Tax Demand — Reclassification of Installation Services as Works Contract Service Held Legally Untenable

Case Background: 3 M India Limited Vs Commissioner of Central Excise (LTU), CESTAT Bangalore

The Customs, Excise and Service Tax Appellate Tribunal (CESTAT), Bangalore, delivered a significant ruling in 3 M India Limited Vs Commissioner of Central Excise (LTU), addressing a critical question in service tax law — whether the Revenue authorities can unilaterally reclassify services already correctly taxed under one category into another, and raise a differential tax demand on that basis. The Tribunal answered this question decisively in favour of the assessee, setting aside the demand in its entirety.

Factual Matrix: The Commonwealth Games Project and the Consortium Structure

The assessee, 3 M India Limited, was duly registered with the Service Tax Department for providing services falling under the categories of Erection, Commissioning or Installation Service as well as Maintenance and Repair Service. During departmental scrutiny of the assessee's ST-3 returns for the period ending September 2010, the Revenue noticed that the assessee had undertaken a significant project for the Delhi Public Works Department (PWD) in connection with the Commonwealth Games, 2010, which involved the supply and installation of retro reflective road signages across various roads in New Delhi.

The Consortium Agreement

The project was not executed by the assessee alone. Rather, it was carried out pursuant to a Consortium Agreement dated 29.08.2009 entered into among three parties:

  1. 3 M India Limited (Consortium Leader) — responsible for the supply of 3M Films and VHB Tapes for all signages awarded under Tender No. NIT No. 67/EE/PWD M-112/09-10
  2. M/s. Bajaj Electricals Limited, Mumbai — responsible for procurement of input materials for the manufacture of sign boards and structures, along with fabrication, erection, installation at project sites, and completion of civil work
  3. M/s. CBM Industries Limited, New Delhi — responsible for procurement of input materials for the manufacture of sign boards

As the Consortium Leader, the assessee raised invoices on behalf of the consortium and discharged service tax liability in respect of the installation of road signages. These invoices clearly and explicitly bifurcated the total invoice value into two distinct components:

  • 80% of invoice value — attributed to the supply of goods/materials, on which VAT @ 4% was duly discharged
  • 20% of invoice value — attributed to the service component, on which service tax @ 10.30% was paid as applicable at the relevant time

The assessee also availed the benefit of Notification No. 12/2003-ST dated 20.06.2003, which permits exclusion of the value of materials from the taxable service value, provided VAT has been paid on such materials. Since VAT had indeed been discharged on 80% of the invoice value representing goods, the assessee legitimately claimed this exemption and paid service tax only on the remaining 20% representing pure services.

The Department's Demand: Reclassification as Works Contract Service

Despite the clear bifurcation in the invoices and the documented payment of both VAT and service tax on respective components, the Revenue formed a different view. The Department took the position that:
