Reassessment power under sales tax law permits fresh determination of the correct tax rate, not just enhancement of liability.

Section 12A of the Karnataka Sales Tax Act authorises reassessment where turnover has escaped assessment, been under-assessed, or taxed at a lower rate, and the reopened proceedings proceed as a fresh assessment. The Assessing Authority is therefore required to determine the correct lawful tax liability on the reassessed turnover, including the proper rate of tax, rather than treating the power as limited to enhancement alone. The contrary view that reassessment could only increase liability was held inconsistent with the scope of the provision, and the Tribunal's finding was set aside in favour of the assessee.

Issues: Whether the power of reassessment under Section 12A of the Karnataka Sales Tax Act, 1957 is confined only to enhancing tax liability, or whether it also permits the Assessing Authority to reopen the assessment afresh and grant a concession in the rate of tax where the turnover has been assessed at a lower rate.

Analysis: Section 12A authorises reassessment where the authority has reason to believe that turnover has escaped assessment, has been under-assessed, has been assessed at a rate lower than the rate at which it is assessable, or that deductions or exemptions have been wrongly allowed. Once reassessment is initiated, the assessment proceedings stand reopened and the original assessment ceases to survive. The reassessment is a fresh assessment, and the authority must determine the correct tax payable on the reopened matter. On the facts, the Assessing Authority had formed the view that certain goods had been taxed at a lower rate than the rate legally applicable, and in the reassessment proceedings the correct rate could be applied. The view that Section 12A could be used only to enhance liability was inconsistent with the scope of the provision and the settled law on reassessment.

Conclusion: The power under Section 12A is not confined to enhancement of tax liability; it extends to a fresh reassessment on merits, including determination of the correct rate of tax. The finding of the Tribunal on this issue was unsustainable, and the petition was allowed in favour of the assessee.

Ratio Decidendi: Reassessment provisions authorising assessment of escaped or under-assessed turnover reopen the assessment afresh, and the assessing authority must determine the lawful tax liability on the entire matter, including the correct rate of tax, rather than treat the power as limited to enhancement alone.
