BIR RDAO No. 33-2026: What Taxpayers Should Know About Denied Refund Claims

Executive Summary

Tax refund claims can involve large amounts of money, strict deadlines, and highly technical rules. For taxpayers claiming VAT refunds, creditable input taxes, or excise tax refunds, a denial from the Bureau of Internal Revenue should never be ignored.

BIR Revenue Delegation Authority Order No. 33-2026 clarifies who within the BIR may sign decisions denying requests for reconsideration of certain refund claim denials.

Under this Order, the Deputy Commissioner of the Legal Group is authorized to sign decisions denying requests for reconsideration of the full or partial denial of a taxpayer’s claim for refund, if the claim was filed and processed within the BIR National Office.

The Order covers refund claims involving creditable input taxes under Sections 112(A) and 112(B) of the Tax Code, and excise tax paid on petroleum products under Section 135-A.

For taxpayers, this is more than an internal BIR delegation. It affects how refund claims are handled, who may issue denial decisions, and how taxpayers should manage their next legal steps after an adverse ruling.

The key lesson is simple: a tax refund claim is not just an accounting submission. It is a legal process that must be carefully documented, monitored, and defended.

What Is BIR RDAO No. 33-2026?

BIR Revenue Delegation Authority Order No. 33-2026 is an official issuance of the Bureau of Internal Revenue dated June 22, 2026.

Its subject is the delegation of authority to sign decisions denying requests for reconsideration of the full or partial denial of certain taxpayer refund claims.

In plain language, this means that when a taxpayer asks the BIR to reconsider a full or partial denial of a covered refund claim, the Deputy Commissioner of the Legal Group may sign the decision denying that request for reconsideration, provided the claim was filed and processed at the BIR National Office.

This delegation is based on Section 7 of the National Internal Revenue Code, which allows the Commissioner of Internal Revenue to delegate certain powers to qualified subordinate officials, subject to legal limitations.

The Order took effect immediately and remains in force until amended, modified, or replaced by another order.

Why This Matters to Taxpayers

At first glance, RDAO No. 33-2026 may look like a purely internal administrative order. But for taxpayers with pending refund claims, it matters.

When a refund claim is denied, the taxpayer must know whether the denial was issued by an official with proper authority. In tax procedure, the authority of the issuing official can affect the validity of a decision and the taxpayer’s next remedies.

A denial of a refund claim may trigger important deadlines. If the taxpayer fails to act within the required period, the claim may be lost. This is why taxpayers should carefully review every BIR decision, including who signed it, what claim it covers, when it was received, and what remedy remains available.

For businesses with substantial VAT input tax or excise tax refund claims, a denial can affect cash flow, financial reporting, and tax planning.

What Refund Claims Are Covered?

RDAO No. 33-2026 applies to specific types of taxpayer refund claims filed and processed within the BIR National Office.

The Order covers:

1. Creditable input taxes under Sections 112(A) and 112(B) of the Tax Code; and

   
   

2. Excise tax paid on petroleum products under Section 135-A of the Tax Code.

   
   

This means the Order is especially relevant to taxpayers dealing with VAT refund claims, input VAT claims, and petroleum-related excise tax refund claims.

It does not necessarily apply to every type of refund claim filed with the BIR. Taxpayers should carefully check whether their particular claim falls within the scope of the Order.

Understanding VAT Refund and Creditable Input Tax Claims

VAT refund claims are common among VAT-registered taxpayers with excess or unutilized input VAT.

This often happens when a taxpayer makes zero-rated sales, export sales, or other transactions where input VAT may accumulate but cannot be fully applied against output VAT.

Sections 112(A) and 112(B) of the Tax Code generally deal with claims for refund or tax credit of input VAT in qualified situations.

These claims are highly technical. The taxpayer must show that the input VAT was validly incurred, properly supported by invoices or receipts, attributable to qualified transactions, not previously applied, and filed within the required period.

A denial may happen for many reasons, including incomplete documents, unsupported transactions, timing issues, defective invoices, mismatch in records, or failure to meet statutory requirements.

Understanding Excise Tax Refund Claims on Petroleum Products

RDAO No. 33-2026 also covers refund claims involving excise tax paid on petroleum products under Section 135-A of the Tax Code.

Excise tax refund claims can arise in specialized industries and transactions involving petroleum products. These claims often involve technical documentation, product classification, proof of payment, statutory entitlement, and compliance with administrative requirements.

Because excise tax refund claims may involve significant amounts, taxpayers should treat them with the same level of care as VAT refund claims.

The refund process should be supported by complete records, clear legal basis, and careful tracking of BIR action or inaction.

What Is a Request for Reconsideration?

A request for reconsideration is a taxpayer’s request asking the BIR to review a prior denial of a refund claim.

In the refund context, the BIR may deny a claim in full or in part. A full denial means the entire claim is rejected. A partial denial means only a portion of the claim is allowed, while the rest is rejected.

When a taxpayer disagrees with the denial, the taxpayer may pursue available remedies under the applicable law and regulations. A request for reconsideration is one possible step, depending on the governing rules and the nature of the claim.

RDAO No. 33-2026 focuses on decisions denying such requests for reconsideration for covered refund claims processed at the BIR National Office.

For taxpayers, the important point is that a reconsideration request must be handled strategically. It should not simply repeat the original claim. It should address the specific reasons for denial, cite legal and factual support, and attach or reference the documents that prove entitlement.

Step-by-Step Guide: What Taxpayers Should Do After a Refund Claim Is Denied

Step 1: Record the Date of Receipt

The first step is to record the exact date when the taxpayer received the denial.

Deadlines in tax cases are strict. The date of receipt may determine the period for filing a request for reconsideration, appeal, or other remedy.

Keep proof of receipt, including registry records, email confirmation, courier tracking, receiving copy, or other documentation.

Step 2: Read the Denial Carefully

Do not focus only on the amount denied.

Review the entire decision. Identify whether the denial is full or partial. Check the reasons given by the BIR. Determine whether the denial is based on missing documents, legal interpretation, computation issues, invoice defects, timing concerns, or factual disputes.

The response strategy depends on the reason for denial.

Step 3: Check the Authority of the Signatory

Because RDAO No. 33-2026 deals with delegated authority, taxpayers should check who signed the denial of the request for reconsideration.

If the claim falls within the scope of the Order and was filed and processed at the BIR National Office, the Deputy Commissioner of the Legal Group may sign decisions denying requests for reconsideration.

Authority matters because tax decisions should be issued by the proper official.

Step 4: Identify the Type of Refund Claim

Determine whether the claim involves creditable input taxes under Sections 112(A) or 112(B), excise tax paid on petroleum products under Section 135-A, or another type of refund.

This helps determine whether RDAO No. 33-2026 applies and what procedural rules should govern the claim.

Step 5: Review the Timeline

Refund claims are deadline-sensitive.

Taxpayers should reconstruct the timeline from the original filing of the claim,

submission of documents, BIR action or inaction, denial, request for reconsideration, and receipt of the reconsideration decision.

If the taxpayer plans to elevate the matter to the Court of Tax Appeals or pursue another remedy, the timeline must be checked immediately.

Step 6: Strengthen the Documentary Record

A refund claim is only as strong as its supporting documents.

For VAT refund claims, this may include VAT returns, invoices, official receipts, schedules, accounting records, contracts, proof of zero-rated sales, proof of payment, and reconciliations.

For excise tax refund claims, this may include proof of excise tax payment, petroleum product documents, importation or purchase records, transaction documents, statutory basis, and other supporting records.

If the BIR denial points to missing or insufficient proof, the taxpayer should determine whether the record can still be strengthened under the applicable remedy.

Step 7: Seek Legal and Tax Advice Before the Deadline Runs

Taxpayers should not wait until the last few days before seeking professional help.

A denied refund claim often requires both accounting review and legal analysis. The taxpayer must assess whether the BIR’s denial is legally correct, whether the decision is properly issued, whether the documents are sufficient, and what remedy is available.

Early review improves the chance of preserving the claim.

Common Reasons Refund Claims Are Denied

Refund claims may be denied for substantive or procedural reasons.

A taxpayer may fail to prove entitlement under the Tax Code. The claim may be filed late.

The supporting documents may be incomplete. Invoices or receipts may not comply with invoicing requirements. The taxpayer’s returns and accounting records may not reconcile. The claim may include unsupported amounts. The taxpayer may have applied the same input tax against output tax. The BIR may disagree with the classification or legal basis of the claim.

For VAT refund claims, documentation is especially important because the taxpayer must clearly establish the connection between the input VAT and qualified transactions.

For excise tax refund claims, the taxpayer must prove that the tax was paid, that the transaction falls within the legal basis for refund, and that the claim complies with administrative requirements.

Legal Protections Taxpayers Should Remember

Taxpayers have the right to due process in refund proceedings.

This includes the right to be informed of the basis of denial, the right to pursue available remedies, and the right to receive decisions from officials with proper authority.

Taxpayers also have the right to keep and present evidence supporting the claim.

However, this right must be exercised within the limits of the applicable rules and deadlines.

Tax refund claims are generally construed strictly against the taxpayer because they involve the return of money from the government. This means the taxpayer must clearly prove entitlement.

But strict rules do not mean the BIR may disregard due process. The BIR must still act within the authority given by law and follow applicable procedures.

Risks and Penalties

The main risk in a denied refund claim is the loss of the refund or tax credit.

For businesses with large VAT input tax or excise tax claims, this can affect cash flow and financial planning. A refund that was expected to support operations, expansion, or working capital may become unavailable.

Another risk is missing the deadline to pursue the next remedy. Once the period to appeal or seek relief expires, the denial may become final.

A poorly handled refund claim may also affect future tax audits. Inconsistent records, unsupported claims, or weak documentation can create additional questions from the BIR.

For corporate taxpayers, a denied refund claim may also affect financial statements, audit disclosures, tax positions, and investor due diligence.

Practical Examples

Example 1: VAT Refund Claim Partially Denied

A VAT-registered company files a refund claim for excess input VAT. The BIR allows part of the claim but denies a portion due to alleged invoice defects and unsupported amounts.

The taxpayer should review the denial carefully, identify the exact disallowed items, check whether documents support the claim, and determine whether a request for reconsideration or appeal is available.

The taxpayer should not assume that a partial denial is automatically final.

Example 2: Denied Reconsideration Signed Under Delegated Authority

A taxpayer files a request for reconsideration after the BIR denies its refund claim. The claim was filed and processed at the BIR National Office. The denial of reconsideration is signed by the Deputy Commissioner of the Legal Group.

Under RDAO No. 33-2026, this delegated authority may apply if the claim falls within the covered refund categories.

The taxpayer should then focus on the next available remedy and the applicable deadline.

Example 3: Refund Claim Filed With Weak Documentation

A company files a refund claim but cannot reconcile its VAT returns, invoices, and accounting records.

The BIR denies the claim for lack of sufficient proof.

This could have been avoided by preparing the refund file before filing the claim, checking documentary requirements, and reconciling records early.

Example 4: Taxpayer Waits Too Long After Denial

A taxpayer receives a denial of a refund claim but delays seeking advice.

By the time the taxpayer reviews the case, the appeal period has already expired.

This is one of the most serious mistakes in tax refund practice. Deadlines should be reviewed immediately upon receipt of any denial.

Best Practices for Taxpayers With Refund Claims

Taxpayers should treat every refund claim as a legal and accounting project.

Before filing, prepare a complete document checklist. Reconcile tax returns, books, invoices, receipts, schedules, and supporting records. Confirm the statutory basis for the claim. Track the filing date and all BIR actions.

After filing, monitor the status of the claim. Keep copies of every submission. Use transmittal letters. Preserve proof of filing and receipt.

If a denial is issued, review it immediately. Identify the reason for denial, determine who signed the decision, check the remedy and deadline, and consult professionals before taking the next step.

For large claims, involve legal counsel early. Tax refund litigation often depends on how well the administrative record was prepared.
