Two of the country's largest oil marketing companies have spent over a decade arguing that selling CNG from their own pumps was simply their own business of selling fuel. The Supreme Court has now told Bharat Petroleum and Hindustan Petroleum that, for the years in question, it was not their fuel to sell in that sense at all; they were acting as commission agents for Mahanagar Gas Limited, and that distinction costs them a service tax bill running past Rs 16 crore.
The dispute covers the period from April 2005 to March 2011, during which BPCL and HPCL distributed CNG to retail customers in Mumbai on behalf of Mahanagar Gas, the city gas distribution company that actually held the supply arrangements and infrastructure. The tax department's case was that this distribution arrangement fit squarely within Business Auxiliary Service under Section 65(19) of the Finance Act, 1994, a category that captures services rendered on behalf of a client, including the kind of agency function BPCL and HPCL were performing for MGL.
Both companies had won before the Customs, Excise and Service Tax Appellate Tribunal, which set aside the demands in June 2014 on the view that distributing CNG through their own retail outlets was an ordinary sale transaction on their own account, not a service rendered to MGL as a client. That characterisation, if it had survived, would have kept the transactions outside the service tax net entirely for those years, since a sale of goods and a taxable service are treated very differently under the statute.
The Supreme Court reversed that finding on the facts. Justices Aravind Kumar and N.V. Anjaria examined how the commercial arrangement between MGL, BPCL and HPCL actually operated, and concluded that Mahanagar Gas retained control over the CNG throughout, including fixing the price at which it was sold to consumers, holding title to the gas, and bearing the commercial risk associated with it. BPCL and HPCL, on this reading, were doing nothing more than facilitating sales on MGL's behalf in exchange for a commission, the textbook definition of a commission agent rather than a principal seller.
That factual finding is what drove the legal conclusion. Once the Court accepted that MGL, not the oil companies, was the real seller bearing price risk and holding title, the service the companies rendered to MGL in getting that gas to the end consumer fell naturally within Business Auxiliary Service, and the earlier Tribunal's contrary view could not stand. The restored demands break down to roughly Rs 8.61 crore against BPCL and Rs 8.08 crore against HPCL, together touching the figure widely reported as Rs 16.68 crore, with some reports rounding it marginally differently to Rs 16.69 crore.
For any company that distributes another entity's product through its own retail network while that other entity keeps control of pricing, title and risk, the judgment is a caution against assuming that physical handling of the goods, or even billing the end customer directly, settles the question of who is the real seller for tax purposes. Commercial control over price and risk, not just who stands at the till, is what the Court treated as decisive in deciding whether a distribution arrangement is a sale on one's own account or a taxable service rendered as someone else's agent.
Oil marketing companies and other distributors operating under similar agency-style arrangements with upstream suppliers will need to revisit how those arrangements are structured and documented, since the same reasoning could reach any distribution network where the upstream principal, rather than the retailer actually dealing with the public, keeps its hands on price, title and risk. The length of time this dispute took to resolve is itself worth flagging for tax planners. The transactions in question ran from 2005 to 2011, the Tribunal ruled in the companies' favour in 2014, and it took the Supreme Court until July 2026 to settle the point finally. Any company that structured a similar distribution arrangement on the strength of the 2014 Tribunal ruling, treating its own-account sale characterisation as settled law, now has to reckon with over a decade of exposure resurfacing in one stroke, a reminder that a favourable Tribunal ruling on a contested classification question is never entirely safe from reversal years down the line. The judgment is likely to feed directly into ongoing and future service tax and GST disputes involving city gas distribution networks, where oil marketing companies frequently act as last-mile retailers for gas utilities that hold the actual city gas distribution licence. Any arrangement replicating the MGL-BPCL-HPCL structure, with the licence holder fixing price and bearing risk while the retailer merely distributes through its own outlets, now carries a live risk of being reclassified as agency service rather than a sale, with the tax consequences that follow from that reclassification applying retrospectively to the full period of the arrangement. Tax counsel advising clients on city gas distribution tie-ups, franchise retail arrangements, or any multi-party distribution chain involving a principal and a retailing agent should treat this judgment as the current benchmark for how the Supreme Court will read such arrangements. Contractual labels describing a relationship as a sale will not control the outcome if the commercial substance, measured by who fixes price, holds title and bears risk, points the other way.
