The Supreme Court has upheld Karnataka’s power to retrospectively restrict a sales tax exemption for imported sugar, but has protected dealers from penalty and retrospective interest for periods when the exemption was still available under the law.
A bench of Justice Aravind Kumar and Justice Prasanna B. Varale partly allowed the appeals concerning the Karnataka Sales Tax Act, 1957. The judgment was delivered on July 13, 2026.
Background of the Case
The dispute concerned the exemption granted to “sugar” under the Fifth Schedule of the Karnataka Sales Tax Act. Before 2001, the statutory entry did not expressly limit the exemption to sugar produced or manufactured in India.
The appellants, Asia Sugar & Chemical Co. and M/s Indian Sugar and General Export Import Corporation Ltd., had dealt in imported sugar during the 1990s. Their original assessments were completed by granting exemption, and they said they had not collected sales tax from purchasers because the commodity was treated as exempt.
In 2001, Karnataka amended the exemption entry by inserting the words “produced or manufactured in India” and declared that the change would be deemed to have existed from an earlier date. Reassessment proceedings were subsequently initiated, resulting in tax demands relating to past transactions.
The Karnataka High Court’s Division Bench upheld the retrospective amendment in 2007 after a Single Judge had earlier struck down its retrospective operation. The matter then reached the Supreme Court.
Supreme Court’s Observation
The Supreme Court first examined whether imported sugar was covered by the exemption before the 2001 amendment.
The Court noted that the earlier entry simply referred to “sugar” and did not contain words restricting the exemption according to the place of production or manufacture. It held that the reference to the Additional Duties of Excise law was intended to identify the commodity and did not automatically introduce an India-origin requirement.
“The expression ‘as described’ is significant. It identifies the goods. It does not, without more, import an origin-based limitation,” the bench observed.
The Court also relied on the fact that the tax department itself had originally granted exemption on imported sugar. It therefore concluded that imported sugar was covered by the exemption before the 2001 amendment.
The bench, however, rejected the challenge to the retrospective amendment itself. It held that the State Legislature had the power to grant, withdraw or restrict a tax exemption and that retrospective operation, by itself, did not make the legislation unconstitutional.
Penalty and Interest
The Court drew a distinction between the principal tax liability and additional consequences such as penalty and interest.
It noted that the dealers had acted when imported sugar was treated as exempt, their assessments had been completed, and tax had not been collected from purchasers. In these circumstances, the Court held that imposing penalty for the earlier period would not be justified.
The bench observed that
“penalty presupposes culpability, default, deliberate breach or at least failure to comply with an existing obligation.”
Accordingly, the Court held that reassessment could continue for determining the principal tax liability. However, no penalty could be imposed for transactions before the 2001 amendment. Interest, if otherwise payable, could be calculated only from the date of the lawful demand following reassessment, and not from the original transaction date.
Decision
The Supreme Court partly allowed the appeals. It affirmed the validity of Karnataka Act No. 5 of 2001 and held that the State could determine and recover the principal tax liability through lawful reassessment.
At the same time, it modified the Karnataka High Court’s judgment by directing that no penalty be imposed for pre-2001 transactions and that interest be calculated only from the date of lawful demand.
The assessing authority was also directed to recompute liability relating to inter-State sales in accordance with the Central Sales Tax Act, 1956, including Section 8(2).
