In the Philippine tax landscape, Sales Invoices (SI) are considered "accountable forms." They are not merely commercial documents but are primary evidence of transactions used to determine Value-Added Tax (VAT) liabilities and deductible expenses. Because the Bureau of Internal Revenue (BIR) maintains strict oversight through the Authority to Print (ATP) system, the loss of these documents carries significant legal and administrative implications.
Is an Affidavit of Loss Required?
Yes. Under existing BIR regulations and the National Internal Revenue Code (NIRC), an Affidavit of Loss is a mandatory requirement whenever a taxpayer loses original copies of Sales Invoices, whether they are unused booklets or copies of issued invoices.
The Affidavit of Loss serves as a formal, notarized testimony under oath. Its primary legal functions are:
- To Notify the State: It informs the BIR that a specific series of serial numbers is no longer in the taxpayer's possession.
- To Mitigate Fraud: It prevents the unauthorized use of the lost invoices by third parties who might attempt to claim fraudulent input VAT.
- To Justify Reconstruction: It provides the legal basis for the taxpayer to use secondary evidence (such as ledger entries or buyer confirmations) to prove sales during an audit.
Procedural Requirements for Reporting Loss
When a loss is discovered, the taxpayer must follow a specific compliance protocol to avoid being cited for "failure to keep/preserve records."
1. Immediate Execution of the Affidavit
The taxpayer (or an authorized representative, if a corporation) must execute a notarized Affidavit of Loss. This document should detail:
- The type of document lost (e.g., VAT Sales Invoice).
- The inclusive serial numbers of the lost invoices.
- The Authority to Print (ATP) number associated with those invoices.
- The circumstances of the loss (e.g., fire, flood, theft, or misplacement).
- A declaration that the documents have not been used for any fraudulent purpose.
2. Police Report (When Applicable)
If the loss is due to theft or robbery, a Police Report or Blotter is usually required by the BIR to supplement the Affidavit of Loss. If the loss is due to a natural disaster (force majeure), a certification from the local government or the Bureau of Fire Protection may be necessary.
3. Formal Notification to the BIR
The taxpayer must submit a letter-notice to the Revenue District Office (RDO) where the business is registered.
- Timeline: This must generally be done within 30 days from the discovery of the loss.
- Attachments: The letter must include the notarized Affidavit of Loss, a copy of the ATP, and an inventory of the remaining (unused) invoices.
4. Publication Requirement
In cases involving a significant volume of lost invoices or where the BIR suspects a high risk of misuse, the taxpayer may be required to publish a notice of loss in a newspaper of general circulation. This serves as a public warning that the specific serial numbers are null and void.
The Impact of the Ease of Paying Taxes (EOPT) Act (R.A. 11976)
Under the Ease of Paying Taxes (EOPT) Act, which became fully effective in 2024 and 2025, the distinction between "Official Receipts" (for services) and "Sales Invoices" (for goods) has been eliminated. The Invoice is now the primary document for both sales of goods and services.
This makes the loss of an invoice even more critical. Since the "Official Receipt" is no longer the primary document for VAT purposes, the "Invoice" is the sole document the BIR will look for during a "Letter of Authority" (LOA) audit to verify output and input VAT.
Penalties and Legal Consequences
Failure to properly report or account for lost Sales Invoices can lead to several penalties under Section 264 of the NIRC and Revenue Memorandum Order (RMO) No. 7-2015:
| Type of Violation | Administrative Penalty |
|---|---|
| Failure to keep/preserve records | PHP 1,000 to PHP 50,000 depending on the nature. |
| Lost Invoices (Unreported) | May be treated as a failure to issue invoices for transactions. |
| Disallowance of Input VAT | If a buyer loses their copy and the seller cannot provide a certified true copy or proof of reporting, the buyer's input VAT claim may be disallowed. |
| Criminal Liability | If the loss is found to be a "willful" attempt to hide income or evade taxes, the taxpayer may face imprisonment of 2 to 4 years. |
Summary Checklist for Compliance
If you have lost a Sales Invoice booklet or specific issued copies:
- Inventory: Determine the exact serial numbers missing.
- Affidavit: Draft and notarize an Affidavit of Loss immediately.
- Report: If stolen, get a police blotter.
- Notify: Submit the documents to your RDO within 30 days.
- Replace: Apply for a new ATP if the lost invoices were unused and you require replacements for daily operations.
