Incomplete and belated sales tax returns can trigger separate penalties, and writ interference is unavailable without jurisdictional error.

An incomplete sales tax return arises where tax and surcharge shown as payable are not remitted, bringing the assessment within section 12(2) of the Tamil Nadu General Sales Tax Act, 1959. On that basis, the shortfall between tax assessed and tax paid attracts penalty under section 12(3)(b). Separately, filing the return beyond the due date independently attracts penalty under section 12(3)(c). The document also notes that where rectificatory relief has failed, no statutory appeal was pursued, and no jurisdictional defect is shown, writ interference is not warranted, including on laches.

Issues: Whether penalty under section 12(3)(b) and section 12(3)(c) of the Tamil Nadu General Sales Tax Act, 1959 was validly levied for an incomplete return and delayed filing, and whether the order was liable to be interfered with in writ jurisdiction.

Analysis: An assessment based on a return in which the tax and surcharge shown as payable were not paid was treated as an incomplete return, and the assessment consequently fell within section 12(2). On that basis, the difference between the tax assessed and the tax paid attracted section 12(3)(b). Separately, section 12(3)(c) was attracted because the return was filed beyond the due date. The attempt to seek relief under section 55 had already failed, no statutory appeal had been pursued, and the Tribunal found no jurisdictional defect or other ground warranting writ interference, including on the ground of laches.

Conclusion: The penalty levied under section 12(3)(b) and section 12(3)(c) was upheld, and interference in writ jurisdiction was declined.

Final Conclusion: The petition failed in its challenge to the penalty and the refusal to grant rectificatory relief, and the assessment-related orders were sustained.

Ratio Decidendi: Where a return is incomplete because tax shown as payable has not been remitted, the case may fall within the penalty provisions for incorrect returns, and delayed filing independently attracts the penalty provision for belated returns; absent jurisdictional error, writ interference is not warranted.
