Provisional sales tax returns and refund provisions can coexist with substantive deductions under a taxing statute.

Rules 20 and 25 of the Punjab General Sales Tax Rules, 1949 were upheld because the Act authorised payment at prescribed intervals and returns by prescribed dates, and the rule-making power extended to the manner, form and time of return filing. The deduction under section 5(2)(a)(vi) was treated as operating at assessment, so quarterly returns could validly proceed on a provisional basis without nullifying the substantive deduction. Where later sales brought the matter within the deduction, section 12 allowed refund of excess tax already paid. The rules were therefore held to be harmonious with the Act and not ultra vires or repugnant to it.

Issues: Whether rules 20 and 25 of the Punjab General Sales Tax Rules, 1949 were ultra vires or repugnant to the Punjab General Sales Tax Act, 1948 because quarterly returns and payment of purchase tax were required before the six-month period allowed for certain deductions had expired.

Analysis: The statutory scheme required tax to be paid at prescribed intervals, returns to be furnished by prescribed dates, and treasury receipts to accompany the returns. The rule-making power under the Act authorised prescription of the manner of payment and the form, authority, and time for furnishing returns. The deduction under section 5(2)(a)(vi) was held to operate at the stage of assessment, while the quarterly return could validly be based on a provisional figure. If later sales brought the case within the deduction, section 12 provided for refund of tax already paid. On this construction, the rules did not nullify the statutory deduction and were capable of harmonious operation with the Act.

Conclusion: The challenge to rules 20 and 25 failed, and they were held to be valid and not inconsistent with the Act.

Final Conclusion: The statutory return and payment machinery was upheld as a valid interim mechanism, with any excess collection protected by the refund provisions of the Act.

Ratio Decidendi: Where a taxing statute authorises prescribed intervals for payment and furnishing of returns and separately provides for refund of excess tax, procedural rules requiring provisional payment and periodic returns are valid if they can operate in harmony with the substantive deduction provisions.
