State of Karnataka v. M/s Durga Projects Inc

Civil Appeal · 2018 INSC 205Decided 6 Mar 2018
Civil Appeal No. 811 of 2018
Chief Justice Dipak Misra · Justice A.M. Khanwilkar · Dr. Justice D.Y. Chandrachud

Background

A Karnataka-based civil contractor sought an advance tax ruling on what rate of sales tax applied to building materials used in its works contracts before 1 April 2006, the date a specific tax provision (Section 4(1)(c)) was added to the Karnataka VAT Act. The tax authority later reversed the earlier favourable ruling, prompting the contractor to appeal to the Karnataka High Court, which ruled in the contractor's favour. The State of Karnataka then appealed that decision to the Supreme Court, along with a batch of connected appeals on the same issue.

Decision Breakdown

The Supreme Court held that even before the 2006 amendment, works contracts were taxable sales under the KVAT Act's general definitions of "sale" and "goods," but the Act did not, before 1 April 2006, prescribe any uniform rate of tax for all goods used in a works contract. The Court rejected the State's argument that the residual provision (Section 4(1)(b), taxing "other goods" at 12.5%) was meant to serve as that uniform rate, holding that a residual entry can only apply to goods not otherwise specifically covered, and could not be stretched to swallow the specific schedule entries. It was only the 2006 amendment inserting Section 4(1)(c) that introduced a genuine uniform rate regime for works contracts. The Court therefore upheld the High Court's ruling and dismissed the State's appeal, along with the connected batch of appeals that turned on the same point.

Lesson Learnt

Tax authorities cannot retroactively stretch a general "residual" tax category to cover a situation the legislature only specifically addressed in a later amendment: a change in law that creates a new uniform rate applies only from the date it takes effect, not before.
