Advance tax rules under sales tax law are ultra vires where the parent Act authorises only annual turnover-based liability.

Delegated rules under the Madras General Sales Tax Act could not require a dealer to pay tax in advance on an estimated turnover before the year ended, because the charging provision imposed liability only on the year's total turnover and the Act contained no express or implied authority for advance collection. The Court held that rules may regulate assessment and collection only within the Act's scope, and a publication clause deeming rules to have the force of enactment does not save rules that are repugnant to the statute. In a taxing statute carrying penal consequences, strict construction applied. The advance provisional tax rules were therefore ultra vires, and the conviction for non-payment could not stand.

Issues: Whether the rules framed under the Madras General Sales Tax Act authorising provisional fixation and collection of tax in advance before the end of the year were ultra vires and inconsistent with the charging provisions of the Act, and whether a conviction for failure to pay such provisional tax could be sustained.

Analysis: The charging section required every dealer to pay tax for each year on the total turnover of that year. The statutory scheme provided for determination of turnover by rules and for assessment, levy and collection in the prescribed manner, but did not itself authorise collection of tax in advance on an estimated turnover before the annual turnover had been ascertained. The rules in question required a newly commencing dealer to submit an estimated return, permitted provisional fixation of tax on that estimate, and compelled monthly payment of one-twelfth of the provisional amount. The Court held that delegated rules may regulate assessment and collection only within the scope of the Act, and cannot create a substantive liability to pay tax in advance when the Act contains no such authority. The provision in the Act that rules, once published, should have effect as if enacted did not prevent judicial scrutiny where the rules were repugnant to the Act. The analogy of advance income-tax under a specific statutory provision did not assist, because no corresponding provision existed in the sales tax enactment. In a fiscal statute carrying a penal consequence, the provisions had to be strictly construed.

Conclusion: The advance provisional tax rules were held to be ultra vires and invalid, and the conviction for non-payment of such tax could not stand.

Final Conclusion: The revision was allowed, the conviction and sentence were set aside, and the fine, if paid, was directed to be refunded.

Ratio Decidendi: Delegated legislation cannot impose a liability to pay tax in advance before the taxable year has ended unless the parent taxing statute expressly or by necessary implication authorises such advance collection; a rule repugnant to the Act is invalid notwithstanding any clause giving it effect as if enacted.
