Explanation to Rule 89(4): Whether the ‘Lesser of Invoice or FOB of Shipping Bill’ ultra vires the CGST Act?
[By Shrushti Taori & Tatva Damania] The authors are students of Maharashtra National Law University, Nagpur and Maharashtra National Law University, Mumbai respectively. Introduction Recently, in Union of India v. Tata Steel Ltd. , the Hon’ble Supreme Court decided on the prospective nature of the Explanation to Rule 89(4) of the Central Goods and Services Rules, 2017 (‘the Rules’) (‘the Explanation’) added vide Notification No. 19/2022 (‘the Notification’). The appeal was against Jharkhand High Court’s judgement in Tata Steel Ltd. v. Union of India , wherein the petitioner challenged the validity of Paragraph 47 of the Circular No. 125/44/2019-GST (‘the Circular’). Paragraph 47 of the Circular directs the authorities to examine the value declared in both the GST invoice and the shipping bill while processing refund claims of unutilised Input Tax Credit (‘ITC’). It further clarifies that the lower of the two values must be considered to compute the eligible refund amount. This was later vis-à-vis incorporated as the Explanation vide the Notification. The very objective of the Explanation is to avoid over-invoicing by the assessee. In Tata Steel, the Hon’ble Supreme Court decided on the prospective application of the Notification. However, it remanded the matter back to the Jharkhand High Court to decide on the merits of the Paragraph 47 the Circular, and hence that of the Explanation. The petition is pending in the Jharkhand High Court. The authors contend that the Explanation to Rule 89(4) of the Rules is ultra vires the Central Goods and Services Act, 2017 (‘CGST Act’), as it imposes a substantive cap on availment of refund on ITC, despite having no such cap in the parent statute. This article frames three arguments to justify the ultra vires nature of the Explanation: (i) the statutory scheme of the CGST Act bases refund of ITC entirely on the invoice only, and shipping bill serves an entirely different purpose; (ii) The CGST Act employs the intention of ‘full refund’, and basing refund on shipping bill does not ascertain ‘full refund’, especially in cases of CIF Contracts; and (iii) Principles laid down in Tanbo Imaging affirms that exports are ‘zero-rated’ and hence, must be tax neutral. Refund on Export in GST Laws Exports are zero-rated supplies under Section 16(1) of the Integrated Goods and Services Tax Act, 2017 (‘the IGST Act’). In cases of zero‐rated supplies under a Bond/Letter of Undertaking (‘LUT’), according to Rule 96A of the Rules, the export is made without the payment of IGST. In such arrangement, the refund of unutilised ITC is later claimed by the exporter under Section 54(3) of the CGST Act. Rule 89(4) of the Rules lays down the formula to calculate the refund of unutilised ITC for that export. It is : Refund = (Export turnover) × (Net ITC) / (Adjusted Total Turnover). Here, Export turnover means turnover of zero‐rated supplies of goods and services, and Net ITC is the input credit availed during the period. The Adjusted Total Turnover is essentially the exporter’s overall turnover (taxable supplies plus zero‐rated services) in a State, excluding exempt supplies and any supplies already refunded under Rules 89(4A)/(4B). Hence, the formula essentially prorates the total ITC based on the share of exports in the total (taxable) business, so that only the portion of credit attributable to exports is refunded. While this mathematical equation precisely gives the amount of refund for that specific export turnover, an important legal issue that arose is the cap on export turnover in this formula. Oftentimes, the transactional value on tax invoice is different than that on the shipping bill for the same product. Hence, vide Paragraph 47 of the Circular, and then vide the Explanation, the Department inserted an explanation to Rule 89(4): it expressly provides that the “value of goods exported” shall be taken as the lower of (i) the Free On Board (‘FOB’) value in the shipping bill; or (ii) the invoice value. According to the Circular No. 197/09/2023- GST (‘2023 Circular’), this ‘lower’ value must be considered in both numerator and denominator in ‘export turnover’ and ‘adjusted total turnover’ while calculating the refund according to the Rule 89(4) of the Rules. The explanation to Rule 89(4) is ultra vires the CGST Act This consideration of the ‘lesser’ value of the invoice or the shipping bill has been challenged in the Tata Steel. It is pertinent to note that the Jharkhand High Court did not decide on the validity of the Explanation yet, nor consider the issue in the judgement. Hence, the Supreme Court remanded the matter back to the Jharkhand High Court to decide on the validity of the Explanation of considering the ‘lesser’ value out of either FOB value of the value on the tax invoice for the purpose of refund of the unutilised ITC. Purpose of invoice and shipping bill, and the scheme of CGST Act for refund of ITC For the purpose of tax, the invoice and the shipping bill serve different purposes. The invoice is issued under Section 31 of the CGST Act r/w Rule 46 of the CGST Rules, whereas the Shipping Bill is issued under Section 50 of the Customs Act, 1962. Even though, according to Rule 96 of the CGST Rules, the Shipping Bill is deemed as a refund application of integrated tax paid on the goods, it is merely a proof of the fact that the good has been exported and the assessee has utilised zero-rated policy, and hence is eligible for the refund. According to the Shipping Bill and Bill of Export (Forms) Regulations, 2017, Form SB I / SB II mandates to list the quantity, description, and declared values (including INCOTERM-based breakdown of FOB, freight, insurance, etc.). However, the valuation of refund as per the Explanation is based on the FOB component only. The invoice, on the other hand, contains total value of supply of goods or services, taxable value of supply of goods or services, rate of tax, and amount of tax charged. For the purpose of valuation, especially that of ITC, the authorities rely on
