On August 3, 2022, the Court En Banr issued a Resolution16 ordering respondent to file its Comment on the Petition for Review, within ten (1 0) days from notice. On August 11, 2022, respondent ftled his Comment (Re: Petition for Review). 17 On August 30, 2022, the Court En Bane issued a Resolution18 submitting this case for decision. THE ISSUE The Court En Bane is confronted with this main issue: "Whether the Court in Division erred in ruling that respondent is not entitled to refund in the aggregate amount ofP11,393,494.01 representing unutilized input value-added tax on purchases ofgoods and services, and importation of goods, all attributable to zero-rated sales for the 1" quarter of2015." THE ARGUMENTS OF THE PARTIES Petitioner states that the Court in Division erred in not holding that respondent is required by law and the Constitution to provide sufficient explanation and specific legal bases for its denial of claim for VAT refund in compliance with due process; that the Court in Division erred in holding that a sale of BOT-registered enterprise is not covered by Section 106(A)(2)(a)(S), of the Tax Code; that the Court in Division erred in preventing the petitioner from complying with the accounting standards and principles on accrual and recognition of sales; that the Court in Division erred in its ruling that a BOT- registered entity cannot be passed on with VAT by all of its local suppliers of goods and services; that the formula that the Court in Division used in computing the allocable input taxes to the different classes of sales is mathematically wrong; and that the Court in Division went beyond its jurisdiction when it ruled on issues not disputed by the parties. On the other hand, respondent states that it is incumbent upon petitioner to prove that it is entitled to refund; that petitioner failed to present sufficient evidence that the recipient of the services are persons engaged in business conducted outside the Philippines when the services were performed.

RULING OF THE COURT ENBANC After a careful review of petitioner's arguments and the records of the case, the Court En Bant finds no reason to reverse the assailed Decision and assailed Resolution of the Court in Division. The records of the case show that the Court in Division had fully and exhaustively resolved the issues raised in this petition. The Court En Bane notes that the arguments presented herein are basically the same arguments offered by petitioner in its Motion for Reconsideration before the Court in Division. Nonetheless, the Court En Bane shall pass upon petitioner's arguments to stress the salient points in the assailed Decision and Resolution. TIMELINESS OF THE PETITION FOR REVIEW The present Petition for Review before the Court En Bam� was timely filed.

Based on the foregoing provision, jurisprudence has laid down certain requisites which the taxpayer-applicant must comply with to successfully obtain a credit/refund of input VAT.

The absence of any of the said requisites is already a valid ground to deny the refund claim. Petitioner mainly argues that it is entitled to refund or tax credit certificate in the amount of 1"11,393,494.01, representing its excess and unutilized input VAT on purchases of goods and services, and importation of goods, for the 1" quarter of 2015.

Pag~ 9 of 19 lll�:c:JSION CL\ J,J~ N() 2629 (CL\ C.\SJ�~ N( ). 9659) The Court En Bane agrees with the findings of the Court in Division that the administrative and judicial claims for refund were ftled within the prescriptive period, that petitioner is a VAT-registered entity, and that petitioner was able to establish that it was engaged in zero-rated sales or effectively zero-rated sales during the subject taxable year. The Assailed Decision ruled as follows: "Based on the foregoing, in order for an export sale to qualify as zero-rated, the following essential elements must be present: 1.) the sale was made by a VAT registered person; 2.) there was sale and actual shipment of goods form the Philippines to a foreign country; and 3.) the sale was paid for in acceptable foreign currency accounted for in accordance with the rules and regulations of the BSP. The sale was made by a VAT registeredperson. 1\s discussed earlier the first essential element was already setded that petitioner is a VAT-registered person. There was sale and actual shipment qfgoodsfrom the Philippines to a foreign country. As for the second essential element, any VAT registered person claiming VAT zero-rated direct or considered export sales must present, among others, the following documents: 1. the sales invoice as proof of sale of goods; and 2. bill of lading or airway bill as proof of actual shipment of goods from the Philippines to a foreign country. Corollary to the first type of document, in proving its zero- rated sales, petitioner must foremost comply with the pertinent invoicing requirements, containing all the required information under Section 113(A) and (B) of the NIRC of 1997, as amended, which provides as follows: "SEC. 113. Invoidng and Accounting Requirements for VAT-registered Per.rons.- (A)Invoidng Requirements.- A VAT-registered person shall issue(.!

(3) The date of transaction, quantity, unit cost and description of the goods or properties or nature of the service; and (4) In the case of sales in the amount of One thousand pesos (P1 ,000) or more where the sale or transfer is made to a VAT-registered person, the name, business style, if r'

XXX XXX XXX In addition to the above requirements, the sales invoices (Sis) and official receipts (ORs) must also be duly registered with the BIR as mandated by Section 237, in relation to Section 238, of the NIRC of 1997, as amended, as follows, viz.: "SEC. 237. Issuance ofReaipts or Sales or Commercial Invoices.- All persons subject to an internal revenue tax shall, for each sale or transfer of merchandise or for services rendered valued at Twenty-five pesos (P25.00) or more, issue duly registered receipts or sales or commenial invoices, prepared at least in duplicate, showing the date of transaction, quantity, unit cost and description of merchandise or nature of service X X X. " "SEC. 238. Printing ofReceipts or Sales or Commerdal Invoices. -All persons who are engaged in business shall secure from the Bureau oflnternal Revenue an authority to print receipts are sales or commercial invoices before a printer can print the same No authority to print receipts or sales or commercial invoices shall be granted unless the receipts or invoices to be printed are serially numbered and shall show, among other things, the name, business style, Taxpayer Identification Number (fiN) and business address of the person or entity to use the same, and such other information that may be required by rules and regulations to be promulgated by the Secretary of Finance, upon recommendation of the Commissioner." Thus, in order for petitioner's export sales to qualify for VAT zero-rating under Section 106(A)(2)(a)(1) of the NIRC of 1997, as amended, it is required to issue VAT Sis for each sale of goods, and the information contained therein must be in compliance with the applicable provisions previously cited, such as the imprinted word "zero-rated" and the taxpayer's TIN-VAT number. In its 1" Quarterly VAT Return (BIR Form No. 2550-Q) for calendar year 2015, petitioner reported total sales in the amount of P2,638,435,170.06, broken down as followsjv'

Mendoza, of Mendoza Querida & Co. However, upon further examination of the said documents, this Court finds that the export sale of goods amounting to US$8,221,401.00 or 1'368,318,809.16 must be disallowed for not being supported with Sis and bills of lading. Consequendy, out is the total declared zero-rated sales of P2,635,483,005.50 for the 1" quarter of calendar year 2015, only the amount of 1'2,267,164,196.34 has complied with the invoicing requirements under the NIRC and RR No. 16-05. As such, petitioner have complied with the second essential element, but only in the amount ofP2,267,164,196.34. Tbe sale waJ�paidfor in acceptable foreign cutTenry accountedfor in accordance witb tbe m!es and regulations qftbe BSP. As for the tbird essential element, petitioner presented as bank certification issued by BDO Unibank, Inc.- Trust and Investments Group, Pioneer, Fasig Branch. This bank certification shows that the payment was made in acceptable foreign currency and accounted for in accordance with the rules and regulations of the BSP. But then, it is also equally important that the foreign currency inward remittance be traced back to the export sales to which it relates. Thus, for the purpose of checking petitioner's compliance with the third essential element, this Court shall only focus on the remaining export sales which are found to be compliant with the invoicing requirements in the amount of 1'2,267,164,196.34. A perusal of the bank certification shows that the foreign remittance for the whole calendar year 2015 is broken down by date of remittance, the remitter, and the amount remitted. On that basis, the ICPA, in his ICPA report dated May 22, 2018, prepared a reconciliation matrix of these remittances per bank certification ,.v'

However, this Court finds that the export sales amounting to US$20,263,358.54 or P899,422,691.13, cannot be properly traced to the inward remittances per bank certification, xxx XXX XXX XXX Accordingly, out of the export sales which were found to be compliant with the invoicing requirements under the NIRC and RR No. 16-05, in the total amount of P2,267 ,164,196.34, only the amount of P1,367,741,505.21 can be properly traced to its corresponding foreign currency inward remittance. Consequently, out of petitioner's declared total zero-rated sales of P2,635,483,005.50 for the subject period, only the amount of P1 ,367,741,505.21 ultimately qualifies as zero-rated sales, in accordance with Section 106(A)(2)(a)(1) of the NIRC of 1997, as amended. 38 Records show that petitioner declared in its Quarterly VAT return for the 1" quarter of calendar year 2015 the amount of P60,276,286.56. Out of the reported total input VAT of P60,276,286.56, petitioner claims refund of the excess input VAT in the amount of P11,393,494.01. Since there is no evidence that the said input VAT are transitional input taxes, thus, petitioner has complied with the requirement that the input taxes being claimed are not transitional input taxes. Furthermore, the Court En Bane agrees with the Court in Division when it disallowed the input taxes on domestic purchases of goods and services for the year covering the subject period of claim because petitioner is not the proper party to seek the tax refund or credit. Petitioner's recourse is not against the government but against the seller who has shifted to it the output VAT. As correctly ruled by the Court in Division in the assailed Decision: "xxx, this Court takes note of Revenue Memorandum Order (RMO) No. 9-00 dated February 2, 2000 which states that sales of goods, properties, or services made by a VAT-registered supplier to a BOI registered entity whose products are 100% exported shall be accorded automatic vxr zero-rating, subject, however, to the following reportorial and documentary requirements, prescribed under Section 3 of the said RMO, xx~ w I kci~ion, pp. 15-21. Cito.ltion~ omitted.

lli�:CJSION CL\ 1'-H NO. 2629 (( 'LI CIS I�: NO. 9659) In the present case, records show that petitioner was issued a Certification by the BOI attesting to the fact that petitioner is a BOT-registered entity with 100% exports for the year 2015. Under Section 3.4 of RMO 9-00, the said BOI Certification shall serve as authority for the local suppliers of petitioner to avail of the benefits of zero-rating on their sales to petitioner on the year 2015. On the basis of the said Certification, no output tax should, therefore, be shifted by the local suppliers to petitioner. It therefore follows that petitioner is not entitled to refund from the said domestic purchases. In the case of Coral Bqy Nickel Cotp. vs. Commissioner ofInternal Revenue, the Supreme Court affirmed the ruling of this Court En Bane in stating that petitioner's recourse is not against the government but against the seller who shifted to it the output VAT, thus: "x x x As such, the purchases of goods and services by the petitioner that were destined for consumption with the ECOZONE should be free of VAT; hence, no input VAT should then be paid on such purchases, rendering the petitioner not entitled to claim a tax refund or credit. Verily, if the petitioner had paid the input VAT, the C'fA was correct in holding that the petitioner's proper recourse was not against the Government but against the seller who had shifted to it the output VAT following RMC No. 41-03, which provides: In case the supplier alleges that it reported such sale as a taxable sale, the substantiation of remittance of the output taxes of the seller (input taxes of the exporter-buyer) can only be established upon the thorough audit of the suppliers' VAT returns and corresponding books and records. It is, therefore, imperative that the processing office recommends to the concerned BIR Office the audit of the records of the seller. In the meantime, the claim for input tax credit by the exporter- buyer should be denied without prejudice to the claimant's right to seek reimbursement of the VAT paid, if any, from its supplier. We should also take into consideration the nature of VAT as an indirect tax. Although the seller is statutorily liable for the payment of VAT, the amount of the tax is allowed to be shifted or passed on to the buyer. However, reporting and remittance of the VAT paid to the BIR remained to be the seller/supplier's obligation. Hence, the proper party to seek the tax refund or credit should be the suppliers, not the petitioner. XXX XXX XXX /""'

Pa,?;c 15 of 19 Dl�:cJSION CT.\ I�:H N< l. 2629 (CT.\< .lSI�: NO 9659) For this reason, this Court is constrained to only consider petitioner's input VAT arising from its importations and from services rendered by non-residents. As such, it is of fatal importance that petitioner provide supporting documents to prove the input taxes claimed from importation of goods and input taxes withheld from services rendered by non-residents during the 1" quarter of calendar year 2015 are actually paid in accordance with Section 110(A)(1)(a) and (2)(b) of the NIRC of1997, as amended, XXX XXX XXX XXX Based on the verification conducted by the ICPA, petitioner's importation ofgoods is either classified as capital goods exceeding 1"1million or non-capital goods. In the ICPA Report, petitioner has a total amortization of input VAT arising from capital goods exceeding P1million in the amount of 1"21 ,578,81 0.54, importation of non-capital goods in the amount of 1"37,147,478.00 and input VAT from services rendered by non- residents in the amount of 1"162,640.21. With regard to the input VXl' arising from importations of non-capital goods in the amount of 1"37,147,478.00, this Court finds petitioner as entitled thereto, considering that it is duly supported by Statements of Settlement of Duties and Taxes (SSD1) and Import Entry and Internal Revenue Declaration (IEIRD) issued by the BOC On the other hand, as to the input VAT amortization amounting to 1"21 ,578,81 0.54, petitioner did not provide a breakdown to show how much of the said amount arose from importations and from domestic purchases of capital goods exceeding 1"1milion. Nevertheless, petitioner presented documents which only support the input VAT on importation of capital goods exceeding 1"1 million with corresponding input VAT amortization of 1"2,368,589.9 5 (1"2,271 ,832.80+1"96,757.15). Meanwhile, petitioner did not submit the corresponding BIR Forms No. 1600 to support its input VAT from services rendered by non-resident amounting to 1"162,640.21. As such, the whole amount must be disallowed outright. /""

However, where there are both zero-rated or effectively zero-rated sales and taxable or exempt sales, and the input taxes cannot be directly and entirely attributable to any of these sales, the input taxes shall be proportionately allocated based on sales volume. In this case, based on the VAT Returns of petitioner, there exist zero- rated sales, exempt sales, and taxable sales subject to 12% VAT Thus, the Court properly allocated the valid input VAT off'39,516,067.95 proportionately based on the volume of petitioner's total sales. Lastly, the Court En Bane holds that petitioner is not entitled to its claim for refund because upon evaluation, the amount of 1"48,780,741.60 that was granted by the BIR for issuance of TCC was beyond the amount found by the Court as petitioner's valid excess input VAT attributable to its zero-rated sales for the subject period of claim. As aptly stated in the assailed Decision: "f"or the period under consideration, petitioner has output VAT liability in the amount of 1"102,050.95.

The pieces of evidence presented entitling a taxpayer to an exemption are also strictissimi scrutinized and must be duly proven.41 In this case, petitioner was not able to prove that it is entitled to a refund in cash in the amount of P11,393,494.01, representing its excess and unutilized input VAT on purchases of goods and services, and importation of goods, for the 1" quarter of 2015.

However, with due respect, I espouse a different view as regards the computation of the amount of excess and unutili zed input VAT attributable to zero-rated sales (or the refundable amount before deducting the amount , already supported by a TCC). As can be deduced from the recent Suprem/

Determine the amount of substantiated or valid input VAT; 2. Deduct from the substantiated or valid input VAT any input VAT directly attributable to a specific activity to arrive at the substantiated or valid input VAT not attributable to any activity; 3� Multiply the substantiated or valid input VAT not attributable to any activity by the ratio of Valid Zero-Rated Sales over Total Sales to determine the amount of substantiated or valid input VAT attributable to valid zero-rated sales; 4� Add to the amount computed in no. 3 any substantiated or valid input VAT directly attributable to zero-rated sales to arrive at the total substantiated or valid input VAT attributable to zero-rated sales; 5� Determine the output VAT still due; 6. Deduct from the output VAT still due any input VAT carried over from previous period to arrive at the amount that may be deemed applied against substantiated or valid input VAT directly attributable to zero-rated sales; 7� Determine the amount of input VAT carried-over instead; and, 8.

As elucidated in Chevron3, it is not for the Court of Tax Appeals (CTA) to determine and rule in a judicial claim for refund under Section u2(A) 4 of the NIRC of 1997, as amended, that the taxpayer had insufficient or unsubstantiated input VAT to cover or pay its output VAT and, for this reason, it is not proper to charge the taxpayer's substantiated or valid input VAT against its output VAT first and use the resultant amount as basis for computing the allowable amount for refund, viz: Fourth, that the taxpayer failed to prove that it had sufficient � creditable input taxes to cover or "pay" its output tax liability in a givey Supra at note I; Citations omitted, emphasis and italics in the original text and supplied.

Commissioner of Internal Revenue Page 5 of8 X------------------------------------------------- X period, hence, there is no refundable "excess" input tax, which is an issue distinct, separate, and independent from a claim for refund or issuance of tax credit certificate of unutilized input VAT attributable to zero-rated sales. For one, the taxpayer-claimant is not asking to refund the "excess" creditable input taxes from the output tax. To be sure, the "excess" input tax may only be carried over to the succeeding periods and cannot be refunded. But, on the other hand, the taxpayer is asking to refund the unutilized or unused input tax from zero-rated sales. Next, the substantiation of input taxes that can be credited against the output tax is an issue relevant to the assessment for potential deficiency output VAT liability. In turn, it is not for the CTA and the Court to determine and rule in a judicial claim for refund under Section n2(A) of the Tax Code that the taxpayer had insufficient or unsubstantiated input taxes to cover its output tax liability. This is for the BIR to determine in an administrative proceeding for assessment of deficiency taxes. All told, it was erroneous for the CTA to charge the validated and substantiated input taxes against Chevron Holdings' output taxes first and use the resultant amount as the basis for computing the allowable amount for refund. The CTA also erred in requiring Chevron Holdings to substantiate its excess input tax carried over from the previous quarter as it is not a requirement for entitlement to a refund of unused or unutilized input VAT from zero-rated sales. We reiterate that although the burden of proof to establish entitlement to a refund is on the taxpayer-claimant, the Court has consistently held that once the minimum statutory requirements have been complied with, the claimant should be considered to have successfully discharged their burden to prove its entitlement to the refund. After the claimant has successfully established a prima facie right to the refund by complying with the requirements laid down by law, the burden is shifted to the opposing party, i.e., the BIR, to disprove such claim. Otherwise, we would unduly burden the taxpayer-claimant with additional requirements which have no statutory nor jurisprudential basis. In the present case, Chevron Holdings sufficiently proved compliance with all the requisites for entitlement to a refund or credit of unutilized input tax allocable to zero- rated sales under Section 112(A) of the Tax Code. From the foregoing, when a taxpayer-claimant has excess input VAT carried over from previous period, it need not substantiate the same for purposes of establishing its entitlement to a refund of excess input VAT from zero-rated sales. The declared excess input tax carried over from previous period is presumed correct and is used to cover or pay for the output VAT still due in the period of claim. It is only when there is no such input tax carried over from previous period, as in this case, or the amount thereof is less than or insufficient to cover the output VAT still due that the , difference or the remaining output VAT may be deducted from or chargt

Furthermore, it must be noted that the option of a VAT-registered taxpayer on whether to charge against output tax from regular 12% VATable sales and any unutilized or "excess" input tax may be claimed for refund or the issuance of a TCC, or whether to claim for refund or tax credit in its entirety, only applies to substantiated input tax attributable to valid zero- rated sales.

Computation of Output VAT Still Due 1'102,050�95 Output VAT 12,7)6.88 Less: Valid Input VAT allocated to VATable Sales Output VAT Still Due P89>J14.07 Table 3� Refundable Excess Input VAT Attributable to Valid Zero-Rated Sales - Valid Input VAT allocated to Valid Zero-Rated Sales 1'20,484.780.85 Less: Output VAT Still Due 89.314.07 Excess Input VAT attributable to Valid Zero-rated sales 1'20,395>466.78 The principle of stare decisis et non quieta movere (to adhere to precedents and not to unsettle things which are established), as ordained in Article 810 of the Civil Code, enjoins adherence by this Court to doctrinal rules established by the Supreme Court in its final decisions, such as the recent pronouncement in Chevron regarding the proper formula for computing the refundable input tax.11 This principle is based on the notion that once a question of law has been examined and decided, it should be considered settled and closed to further argument.12 The High Court's interpretation of a statute becomes part of the law as of the date it was originally passed because such interpretation simply establishes the contemporaneous legislative intent that the interpreted law carries into effect.'3 Nonetheless, since the amount already supported by a TCC of P48,780,741.6o is still above and beyond the amount of excess and unutilized input VAT attributable to valid zero-rated sales of 1'20,395.466.78, as recomputed, petitioner is not entitled to any additional amount of refund. All told, I vote to DENY the instant Petition for Review for lack of merit. ( JEAN 10 ART. 8.
