Quick answer

Report the supplier to the Bureau of Internal Revenue through the BIR eComplaint System. Choose eComplaint NO-OR when available: the BIR expressly treats the use of unregistered, fake, or spurious receipts or invoices as a “NO-OR” complaint. If the documents appear to form part of a broader tax-evasion scheme—such as fabricated purchases, ghost transactions, or multiple fake invoices—you may also identify the matter as potentially appropriate for R.A.T.E. evaluation.

Keep the original document and submit clear copies together with proof of the real transaction and payment. State only what you personally know. Describe the document as “suspected fake” unless its falsity has already been confirmed by the BIR or another competent authority.

Ask the supplier in writing for a valid, BIR-compliant invoice. Since the Ease of Paying Taxes reforms took effect, an invoice—not an official receipt—is generally the primary document evidencing a sale of goods or services for tax purposes.

First, check whether the document is actually fake

An unusual-looking document is not automatically fraudulent. Possible warning signs include:

The supplier’s registered name, TIN, or business address is missing or inconsistent with its other records.
The invoice number appears altered, duplicated, erased, or overwritten.
The document bears another taxpayer’s name or TIN.
The supplier denies issuing it, or the supposed transaction never occurred.
The amount or description materially differs from what was sold or paid.
The document appears to come from an unauthorized printer or series.
Two versions bearing the same serial number show different transactions.
A VAT amount is charged even though the document does not identify the seller as VAT-registered.
The supplier presents a collection receipt, acknowledgment receipt, order slip, statement of account, or similar supplementary document as though it were the primary tax invoice.
A purported invoice is marked “not valid for claim of input tax,” or lacks information required for a VAT invoice.

These are indicators, not final proof. A genuine invoice may contain an error, while a professionally printed document may still be spurious.

The “official receipt” terminology has changed

Republic Act No. 11976, or the Ease of Paying Taxes Act, amended the Tax Code so that sellers issue duly registered sales or commercial invoices for sales of both goods and services. Under the current general rule:

VAT-registered sellers must issue an invoice regardless of the transaction amount.
Other persons subject to internal revenue tax must generally issue an invoice for a transaction worth at least ₱500, or whenever the buyer asks for one regardless of amount.
Below the threshold, the seller must issue an end-of-day invoice for aggregated sales if the aggregate reaches at least ₱500.

The ₱500 statutory amount is subject to adjustment every three years using the Philippine Statistics Authority’s consumer price index. See Republic Act No. 11976, Sections 35–36 and BIR Revenue Regulations No. 7-2024.

An “Official Receipt” issued after the transition is not necessarily counterfeit. For example, BIR rules allowed unused manual official receipts to be converted and used as primary invoices if the required information was supplied and the word “Invoice” was properly stamped. Without the prescribed conversion, an official receipt generally functions only as a supplementary document evidencing collection, not as the primary invoice for the sale. The transition rules and their deadlines matter, so check the document’s date. See BIR Revenue Regulations No. 11-2024 and BIR Revenue Memorandum Circular No. 77-2024.

Evidence to preserve before reporting

Keep the original document unchanged. Do not write on it, tear it, laminate it, or return it without first making complete copies. Preserve:

Front-and-back photographs or scans of the receipt or invoice
All pages, attachments, and duplicate copies provided
Purchase order, contract, quotation, delivery receipt, statement of account, and acknowledgment receipt
Proof of payment, such as a bank record, card slip, e-wallet confirmation, deposit slip, or cleared check
Messages and emails discussing the order, price, payment, and request for an invoice
The supplier’s website, marketplace listing, social-media page, and advertised business details
The supplier’s full name, trade name, address, contact details, and stated TIN
Date, time, location, items or services purchased, quantity, and amount
Names and contact details of people who witnessed the transaction
Any written refusal, replacement offer, admission, threat, or explanation from the supplier
Other documents bearing the same serial number or showing a recurring pattern
Screenshots showing the full page, account name, date, and URL—not merely cropped excerpts

For electronic files, retain the original email or downloaded file where possible. Screenshots alone may omit useful metadata. Back up the evidence in a secure location and restrict access to people who need it.

Prepare a short chronological account. Separate direct observations from suspicions. For example: “I paid ₱___ on ___ and received the attached document” is a fact; “the supplier operates a nationwide fake-receipt syndicate” is an allegation that requires independent evidence.

How to file the BIR complaint

1. Ask for a corrected, valid invoice

Send the supplier a written request identifying:

The transaction and payment date
The defective or suspicious document number
The specific discrepancy
Your request for a duly registered and accurate invoice
A reasonable date for a response

Do not delay reporting merely because the supplier ignores the request. Do not agree to backdating, alteration of the original, use of another entity’s invoice, or a replacement that describes a transaction different from the one that occurred.

2. Submit an eComplaint

Go to the official BIR eComplaint portal and select NO-OR. Under BIR Revenue Memorandum Order No. 28-2021, NO-OR complaints include non-issuance of invoices and the use of invoices or receipts not duly registered with the BIR, including fake or spurious documents.

Provide as much verifiable information as possible:

Supplier’s registered or advertised name
Trade name, branch, and exact business address
TIN shown on the document, if any
Invoice or receipt number
Transaction and issuance dates
Goods or services involved
Amount paid and method of payment
Why you believe the document may be fake or unregistered
Whether you requested a valid invoice and how the supplier responded
Whether the same conduct affected other transactions
Your attachments and contact details

Use neutral, precise language. A useful description is:

I am reporting a suspected fake or unregistered invoice. On [date], I purchased [goods/services] from [supplier] for ₱[amount] and paid through [method]. The supplier issued document no. [number], attached. I became concerned because [specific, verifiable discrepancy]. I requested a valid invoice on [date], but [response]. Attached are the document, proof of payment, transaction records, and correspondence. I request verification and appropriate action.

Save the submission confirmation, reference number, screenshots, and copies of everything uploaded.

3. Use the correct category for a broader scheme

If the facts suggest deliberate tax evasion beyond one defective invoice—such as numerous fictitious transactions, ghost suppliers, systematic use of duplicate invoice sets, or fabricated purchases—describe those facts and consider the portal’s R.A.T.E. category. Do not characterize an ordinary formatting mistake as tax evasion without supporting evidence.

BIR rules route taxpayer-violation complaints to the Revenue District Office with jurisdiction over the person or entity concerned, with monitoring by the appropriate investigation and enforcement offices. See BIR Revenue Memorandum Order No. 28-2021.

4. Follow up through official BIR channels

Keep the complaint reference number. The BIR’s published contact number is (02) 8538-3200, as shown on the BIR website.

BIR rules state that complaints received through recognized channels should be acknowledged within the same day, or the next business day if received on a weekend or holiday. That is an acknowledgment standard, not a promise that the investigation will be completed within that period. The time needed for verification or enforcement depends on the evidence and the case.

5. If online filing does not work

Contact the BIR and ask for the correct Revenue District Office or current alternative filing channel. A taxpayer-violation complaint is ordinarily handled by the RDO that has jurisdiction over the supplier.

Do not send sensitive tax or identity records to an address found only on social media or an unofficial website. Confirm any email address or physical filing instruction through the current BIR website or hotline.

Can the complaint be anonymous?

The BIR can process an anonymous complaint if it contains verifiable leads. Under Revenue Memorandum Order No. 28-2021, an anonymous complaint with no contact information that fails to identify the subject may be closed without further action.

An anonymous report is therefore more useful when it identifies the supplier, location, transaction, document number, date, and supporting evidence. Providing contact details may allow investigators to request clarification, but consider legal advice first if disclosure could create a real safety, employment, or retaliation risk.

Do not assume that your identity will remain confidential in every later proceeding. If the matter develops into a criminal or judicial case, evidentiary and due-process requirements may affect whether testimony or records are needed.

What the law requires from suppliers

Under Section 237 of the Tax Code, as amended by Republic Act No. 11976, required invoices must be duly registered and show prescribed information, including the seller’s name, TIN, transaction date, quantity, unit cost, and description of the merchandise or nature of the service.

Section 238 requires businesses to secure a BIR Authority to Print before a printer produces manual invoices. The invoices must be serially numbered and bear required taxpayer information. Computerized or electronic invoices are governed by additional BIR rules and permits or registrations applicable to the system used.

Section 264 of the Tax Code addresses conduct that includes:

Failure or refusal to issue a required invoice
Issuing an invoice that does not truthfully reflect the transaction
Omitting required information
Using multiple or double sets
Printing invoices without BIR authority
Printing double, multiple, or unnumbered sets
Printing documents without prescribed taxpayer details

Criminal liability and penalties require proper investigation, prosecution, and conviction. A complainant should report the facts rather than announce that the supplier is guilty. Different provisions may apply to the supplier, printer, buyer, or intermediary depending on what each person knowingly did.

If you are a business buyer

Do not knowingly record a fake invoice as a valid expense or use it to support an input-VAT claim. Alert the person responsible for accounting, tax, compliance, or internal audit.

Practical precautions include:

Quarantine the document in your accounting system.
Do not alter or destroy the original entry or audit trail.
Preserve the purchase, delivery, and payment records.
Determine whether the transaction was genuine despite the defective document.
Request a compliant replacement from the actual supplier.
Check whether the invoice has already been included in a tax return, VAT schedule, reimbursement, liquidation, or financial statement.
Have a Philippine tax professional assess whether an amendment, adjustment, disclosure, or other corrective action is needed.

A genuine purchase and a valid tax invoice are separate issues. Proof that goods were delivered does not automatically cure a defective invoice for VAT purposes. Conversely, a document defect does not by itself prove that no transaction occurred.

Because tax treatment depends on the seller’s registration, the invoice date, the information omitted, the tax period, and what your business has already filed, do not make a VAT claim or amend a return based solely on a general checklist.

Other reporting options may apply

A BIR complaint addresses the tax-document violation. It does not automatically recover your payment, resolve a defective-product dispute, or prosecute unrelated fraud.

Depending on the facts:

A consumer may have a separate complaint concerning deceptive sales practices or failure to honor a lawful transaction.
A forged document used to obtain money or property may justify consultation with the police, National Bureau of Investigation, or a lawyer.
A government procurement transaction should be escalated promptly to the procuring entity’s legal, internal-audit, and compliance officers.
A regulated supplier may also be answerable to its licensing or supervisory agency.

Avoid filing identical, unsupported accusations everywhere. Explain to each agency the particular conduct within its authority, and disclose related complaint reference numbers when appropriate.

Common mistakes to avoid

Calling every post-EOPT official receipt “fake” without checking the transition rules
Treating a payment acknowledgment or delivery receipt as the required tax invoice
Returning the only original before making complete copies
Editing screenshots or marking the suspected document
Posting the accusation publicly before verification
Threatening the supplier or demanding money in exchange for silence
Accepting an invoice issued under an unrelated person’s name or TIN
Agreeing to a false transaction date, amount, item description, or purchaser name
Claiming input VAT from a document known to be questionable
Reporting only a vague business nickname without an address, date, or transaction details
Inventing details to make an anonymous complaint appear stronger
Expecting the BIR to recover the purchase price as part of a tax complaint
Ignoring follow-up requests or losing the complaint reference number

Is there a deadline to report?

The cited BIR complaint rules do not prescribe a single consumer filing deadline specifically for reporting a suspected fake invoice. Report promptly while documents, messages, CCTV footage, platform records, and witnesses remain available.

Businesses must also comply with applicable tax-record retention rules. Section 235 of the Tax Code generally requires books of accounts and other accounting records to be preserved for five years, reckoned as specified in the statute. Longer preservation may be prudent when a transaction is disputed, under investigation, or relevant to pending litigation. A separate civil, criminal, tax, procurement, or platform claim may have its own deadline.

When legal or tax help is urgent

Seek advice promptly if:

Your business already claimed input VAT or a deduction using the document.
The suspected invoices involve large amounts, many transactions, or multiple entities.
The supplier asks you to backdate or falsify records.
An employee or agent may have participated in the scheme.
You receive a BIR letter, subpoena, assessment notice, or request for testimony.
The document concerns government funds, public procurement, or grant liquidation.
You are being threatened or pressured to withdraw the report.
Money was obtained through possible forgery, identity theft, or organized fraud.
You need to preserve evidence held by a bank, marketplace, courier, or telecommunications provider.
You are considering a civil or criminal case in addition to the BIR complaint.

If there is an immediate threat to personal safety, contact local law enforcement rather than confronting the supplier.

Frequently asked questions

Should I report an “official receipt” or an “invoice”?

Use the BIR’s NO-OR complaint category even when the disputed document is called an invoice. The BIR’s governing complaint order defines NO-OR broadly enough to include fake or spurious receipts and invoices.

Is an official receipt issued after April 27, 2024 automatically fake?

No. It may be a valid supplementary receipt, or it may have been validly converted for transitional use by stamping “Invoice” and complying with BIR requirements. Its date, wording, required details, and the applicable transition rule must be checked.

Can I demand an invoice for a purchase below ₱500?

Yes. Under Section 237 as amended, the seller must issue an invoice when the buyer requires one regardless of the amount. VAT-registered sellers must issue an invoice regardless of transaction value.

Can I verify conclusively from the appearance of the document?

Usually not. Visual defects can raise suspicion, but BIR records concerning the taxpayer, Authority to Print, serial-number series, and invoicing system may be needed for confirmation.

Can I report without knowing the supplier’s TIN?

Yes, but provide enough identifying information for verification: exact business name, trade name, branch, address, contact details, transaction date, payment record, and images of the document. Include the TIN if it appears on the document; do not guess it.

Will the BIR refund what I paid?

A BIR tax complaint ordinarily seeks compliance and enforcement, not reimbursement of the purchase price. Recovery may require a separate consumer, contractual, civil, platform, or criminal remedy.

May I claim input VAT while the supplier replaces the document?

Do not assume that a questionable receipt or invoice supports input VAT. The answer depends on the document, transaction, seller’s VAT status, timing, and current BIR rules. Have the records reviewed before claiming or retaining the credit.

What if the supplier says it was only a printing error?

Preserve that explanation and request a compliant replacement. A genuine clerical error and a deliberate fake-invoice scheme are legally different. The BIR can determine whether the document was authorized and properly issued.
