Reformatting a computer or replacing a hard drive may seem like an ordinary IT task, but it becomes a tax-compliance issue when the device runs a BIR-registered point-of-sale system. A reformat can erase the electronic journal, reset counters, interrupt invoice serial numbers, change the approved software version, or break the link between the machine and its Permit to Use. The correct procedure depends on what will change, whether the old sales data will remain accessible, and whether the machine will continue under the same taxpayer, branch, hardware, and accredited software.

Do You Need a New BIR Permit to Use After Reformatting?

The BIR does not provide a separate application called “permission to reformat.” Instead, the tax treatment depends on the actual effect of the work on the registered POS system.

Situation	Likely BIR treatment
Same taxpayer, branch, hardware, accredited software, and software version; all sales data, counters, and invoice sequences remain intact	Usually treated as maintenance rather than a new registration. Keep a written notice and complete technical records, and obtain written confirmation from the RDO when there is any doubt.
Operating system or storage device is reformatted, causing a system reset	Notify the RDO or Large Taxpayer office within three days after the reset and attach the required Z-Reading or End-of-Day report.
Software version, database platform, financial computation, modules, reports, or bundled hardware changes	May constitute a major enhancement, requiring prior BIR notification and approval, supplier reaccreditation, and possibly a new Permit to Use.
POS is moved to another branch	Cancel the existing Permit to Use and register the system for the receiving branch.
Machine is sold, retired, transferred to a new franchisee, or assigned to another taxpayer	Cancel the old Permit to Use. The old permit and Machine Identification Number cannot simply be inherited by the new user.
Supplier’s Certificate of Accreditation has expired, but the taxpayer continues using the same approved system	The taxpayer’s existing Permit to Use does not expire merely because the supplier’s accreditation certificate expired.

This classification follows the distinction in BIR Revenue Memorandum Order No. 24-2023 between major and minor enhancements, together with the rule in Revenue Regulations No. 6-2022 that an unauthorized major repair, upgrade, integration, modification, or alteration can be a ground for revoking the Permit to Use. (Bir Cdn)

Because “reformatting” can mean anything from reinstalling Windows to replacing the entire database and application, the safest practical approach is to describe the proposed work in writing and ask the RDO to confirm whether it is maintenance, a minor enhancement, or a major enhancement before the work begins.

Important BIR Terms You Should Understand

Permit to Use

A Permit to Use, commonly called a PTU, is the BIR authorization allowing a taxpayer to use a particular CRM, POS machine, or similar sales software to generate invoices.

A PTU is tied to details such as:

The registered taxpayer and branch
Business address
Machine serial number
POS software and version
Supplier or software provider
Machine Identification Number
BIR accreditation information

Under the current BIR Citizen’s Charter, applications for POS permits are processed online through the Enhanced Electronic Accreditation and Registration System, or eAccReg. For CRM and POS applications, the accredited software supplier or provider ordinarily files the application on behalf of the taxpayer, while the taxpayer accesses the system to print the approved PTU. The published processing time is two days, with no BIR processing fee.

Machine Identification Number

The Machine Identification Number, or MIN, is the unique number assigned to the registered machine or software through eAccReg. A reformat should not result in the unauthorized creation of a different machine identity or the reuse of an MIN belonging to another branch, taxpayer, or device.

Z-Reading or End-of-Day Report

A Z-Reading or End-of-Day report closes or summarizes the day’s recorded transactions. It is one of the most important documents when a machine is reset, retired, transferred, inspected, or cancelled.

Grand accumulated sales and reset counter

An accredited POS system must maintain audit features that allow the BIR to trace recorded sales. These normally include accumulated grand total sales, transaction logs, an electronic journal, backend reports, sequential invoice numbers, reprint capability, and non-volatile data storage or recovery features. (Bir Cdn)

A legitimate reset must not be used to conceal or erase taxable sales. The reset counter should reflect the reset event, while the required sales records and audit trail must remain available.

Legal Basis for the BIR Requirements

The principal rules are found in several related BIR issuances.

Revenue Memorandum Order No. 24-2023

RMO No. 24-2023 contains the current accreditation and registration framework for CRMs, POS systems, mobile sales devices, subscription-based invoicing systems, and other machines or software that generate invoices.

It requires covered sales machines and software to be accredited and registered through eAccReg. It also distinguishes between:

Major enhancements, which generally require a new accreditation application and evaluation; and
Minor enhancements, which do not require reaccreditation but must still be reported to the concerned RDO or Large Taxpayer office.

Examples of major changes include altered functionality, new financial computations, additional reports, a different database platform, software version upgrades, or hardware changes in a bundled POS system. Examples of minor changes include rearranging user-interface fields, adding transparent security controls, or making modifications that do not affect system functionality.

Revenue Regulations No. 6-2022

RR No. 6-2022 removed the former five-year validity period of POS permits. A PTU remains valid unless revoked.

However, possible grounds for revocation include:

Tampering with sales data or software integrity
Altering the system to avoid recording sales
Performing a major repair, upgrade, integration, or modification without prior BIR notification and approval
Changing financially significant functionality or modules without authority

(Bir Cdn)

Revenue Memorandum Circular No. 69-2020

RMC No. 69-2020 governs cancellation of POS and CRM permits, including cancellation because of retirement, withdrawal from use, software replacement, transfer, or similar changes. It also provides rules for inspection, final readings, cancellation certificates, and simultaneous registration of replacement software. (Bir Cdn)

Ease of Paying Taxes Act and current invoicing rules

Republic Act No. 11976, the Ease of Paying Taxes Act of 2024, amended the National Internal Revenue Code to make an invoice the primary sales document for both goods and services. It also requires accounting records to be preserved for five years from the applicable statutory starting point. Read Republic Act No. 11976 on Lawphil. (Lawphil)

Under Revenue Regulations No. 7-2024, as amended, a restored POS should generate an Invoice, such as a Sales Invoice, Service Invoice, Cash Invoice, or another permitted description containing the word “Invoice.” An old backup that restores “Official Receipt” as the primary sales document should not be placed back into live use without correcting the template. (Bir Cdn)

Step-by-Step Process Before Reformatting and Reusing a POS System

1. Identify the exact registered POS configuration

Before any technician touches the device, prepare a machine profile containing:

Registered taxpayer name and TIN
Branch code and registered business address
Permit to Use number
Machine Identification Number
Machine serial number, brand, and model
Software name and version
Supplier or developer
Certificate of Accreditation number
Last invoice serial number
Current Z-Reading number
Reset-counter reading
Accumulated grand total sales

Compare these details with the PTU, BIR decal, system settings, and the supplier’s records. A serial-number or branch mismatch is a common reason an RDO delays approval or requires further inspection.

2. Ask the vendor for a written technical scope

The POS supplier or technician should describe exactly what the work will involve.

The document should state:

Why reformatting is necessary
Whether the operating system alone will be reinstalled
Whether the POS software will be reinstalled
Whether the same accredited version will be used
Whether the database will be restored
Whether any hardware will be replaced
Whether the MIN, counters, and invoice sequence will remain unchanged
Whether a reset will occur
How historical data will remain accessible
Date and expected duration of the work

A statement that the technician will “just reformat the unit” is not enough. The tax consequence depends on the technical details.

3. Make a complete pre-reformat backup

Before shutting down the POS, generate and preserve:

Final Z-Reading or End-of-Day report
Backend sales report through the last day of use
Electronic journal or audit journal
Activity and transaction logs
Reprint of the last invoice issued
Invoice serial-number report
Accumulated grand total sales
Current reset-counter and Z-counter readings
Product, tax, discount, and user configuration
Full database and application backup

Keep at least two backup copies on separate storage media. The vendor should test that the backup can actually be restored; copying a damaged database file is not a reliable backup.

The five-year preservation rule applies to accounting records even when the physical POS device has been replaced or reformatted. (Lawphil)

4. Notify the RDO before any potentially major change

Send a letter to the RDO or Large Taxpayer office where the POS is registered when the work may involve:

A new POS version or release number
Changed financial computations
Addition or removal of modules
A different database platform
Integration with another accounting, inventory, or payment system
Replacement of registered bundled hardware
New invoice or tax logic
Migration from local storage to cloud storage
Any change affecting reports, audit trails, serial numbers, or accumulated sales

Attach the vendor’s technical scope, current PTU, machine profile, and before-work reports. Ask the BIR to confirm whether prior approval, reaccreditation, cancellation, or a new PTU is required.

A receiving copy stamped by the BIR is valuable. An informal verbal statement from a technician or front-desk employee is difficult to prove during a future audit.

5. Reformat under controlled conditions

Schedule the work after the final business transaction for the day. During the downtime:

Stop issuing invoices from the affected POS.
Use duly registered manual invoices when transactions must continue.
Record all downtime sales completely.
Do not reuse skipped or previously issued serial numbers.
Do not use an unregistered substitute laptop, tablet, or POS terminal to issue invoices.
Do not allow the technician to delete audit logs merely to make the installation easier.
Reinstall only the BIR-accredited software and approved version unless a different version has already been cleared.

After restoration, any downtime sales recorded manually should be properly reflected in the taxpayer’s books and tax reports without recording the same sale twice.

6. Submit the mandatory notice if the POS was reset

When a CRM or POS is reset, RMO No. 24-2023 requires the taxpayer to notify the concerned RDO so the BIR can verify that sales through the last day of use were recorded.

The letter notification must be submitted not later than three days after the reset, accompanied by the printed Z-Reading or End-of-Day report as of the reset date. The report should allow validation that the reset counter increased by one. Failure to submit the required letter may result in a penalty of ₱1,000 for each omitted notification, subject to an aggregate annual ceiling of ₱25,000 under the cited Tax Code provision.

Because the rule states “three days,” not “three working days,” businesses should use the more conservative calendar-day computation unless the concerned BIR office gives written instructions otherwise.

A useful reset notice contains:

Taxpayer name, TIN, and branch
Registered address
PTU number and MIN
Machine serial number
Software name and version
Date and time of reset
Reason for reset
Last invoice number before reset
Before-and-after counter readings
Confirmation that the database and historical sales were preserved
Vendor or technician’s name and service-report reference

7. Conduct a compliance test before live reuse

Do not assume that a successful login means the system is BIR-compliant. Verify all of the following:

Correct taxpayer name, TIN, branch, and address
Correct PTU and accreditation details
Correct machine serial number and MIN mapping
Continuation of invoice serial numbers
Access to prior electronic journals and backend reports
Correct accumulated sales and counter readings
Proper VAT, VAT-exempt, zero-rated, and non-VAT treatment
Correct senior citizen, PWD, and other discount computations
Proper invoice date and time
Invoice heading uses “Invoice,” not merely “Official Receipt”
Required description of goods or nature of services
Proper quantity, unit cost, totals, and tax breakdown
Audit trail records the reinstallation, reset, and configuration changes

Any test document generated through the live invoice sequence should be handled through the system’s normal audited voiding or cancellation function. It should not simply be deleted from the database.

When Cancellation and a New PTU Are Required

Cancellation should be expected when the machine or software will no longer be used under its existing registration, including:

Retirement or permanent withdrawal
Sale to another person
Transfer to another branch
Use by a new franchisee
Closure of the registered branch
Replacement of the registered machine
Installation of a materially different accredited software system
Changes that the RDO determines require a new PTU

The current BIR Citizen’s Charter lists the following standard cancellation requirements:

Requirement	Practical note
Original cancellation-request letter	State the reason and complete machine details.
Notarized sworn statement, if applicable	Include machine readings and relevant facts.
Original Permit to Use	Explain in an affidavit if genuinely lost.
Original BIR decal	Preserve it before disposing of or transferring the equipment.
Z-Reading as of the last day of use	Keep a clear original or reprint.
Backend report or cash-register sales book	Totals should reconcile with the Z-Reading.
Reprint of the last invoice	Check the final serial number and date.
Authorization documents	SPA for an individual representative, or board resolution, written resolution, or secretary’s certificate for a corporation or other non-individual taxpayer, plus IDs.

The BIR’s published processing time for cancellation is seven days, with no processing fee. The process ordinarily includes an ocular inspection and evaluation of the final readings.

RMC No. 69-2020 also requires taxpayers to notify the RDO or Large Taxpayer office in writing within five days from the machine’s last use or withdrawal. For software replacement or an upgrade on the same hardware, the BIR may dispense with physical inspection in limited circumstances, but this should not be assumed without confirmation. (Bir Cdn)

For a replacement POS, the accredited supplier normally submits the new PTU application through eAccReg. The taxpayer should not begin issuing live invoices from the replacement configuration until the required approval has been secured.

Common Reformatting and POS Reuse Scenarios

The hard drive failed, but the same POS software will be restored

When the same terminal, accredited software version, database, historical transactions, counters, and invoice sequence are fully restored, the work is more likely to be regarded as repair or maintenance.

Keep:

The technician’s diagnosis
Before-and-after configuration
Backup and restoration report
Final pre-failure Z-Reading
After-restoration validation reports
Written RDO notice
Reset notice, when a reset occurred

If the hard-drive failure destroyed the database or caused the counters to restart, the case is no longer a simple maintenance situation.

The business will reuse the software on a different computer

Using the same software does not automatically mean the existing permit covers the new computer. The registered serial number, hardware architecture, and MIN may no longer match.

Hardware changes in a bundled POS may be treated as a major enhancement. Obtain written BIR instructions and expect either an amendment, cancellation and replacement, or a new PTU.

The POS will be transferred from one branch to another

A PTU is not a floating permit that can be moved wherever the business needs an extra terminal. The existing permit should be cancelled, the machine inspected when required, and a new PTU obtained for the receiving branch. The current Citizen’s Charter expressly includes transfer to another branch among the reasons for cancellation.

The business bought a secondhand POS machine

The buyer cannot lawfully use the seller’s PTU, MIN, taxpayer information, or invoice sequence. The seller should complete cancellation, and the buyer must register an accredited configuration under the buyer’s own taxpayer and branch details.

The restored backup still prints “Official Receipt”

Since April 27, 2024, an invoice is the primary document for sales of goods and services. An Official Receipt is generally a supplementary document. A POS that has reverted to an old “Official Receipt” template should be corrected before live use. (Bir Cdn)

The BIR previously treated the renaming of a POS-generated Official Receipt to an Invoice as a minor system enhancement, provided serial continuity and reporting rules were followed. That transitional treatment does not authorize a business in 2026 to restore and continue using a noncompliant old template.

The supplier’s accreditation expired

The taxpayer does not need to cancel a valid PTU solely because the supplier’s Certificate of Accreditation expired. RMC No. 72-2025 confirms that POS and CRM permits do not expire and are not automatically cancelled when the supplier’s accreditation certificate expires. The supplier may nevertheless need to secure new accreditation under RMO No. 24-2023.

The business is foreign-owned or managed by a foreigner

Foreign ownership does not create a separate POS registration system. The Philippine-registered business remains subject to the same BIR requirements.

When another person files documents for the taxpayer:

An individual taxpayer normally uses a specific Special Power of Attorney.
A corporation uses a board resolution, written resolution for a one-person corporation, or secretary’s certificate.
Government-issued identification documents of the relevant signatory and representative are required.

These representative requirements appear in the current BIR Citizen’s Charter.

Common Mistakes That Cause Problems

Businesses frequently encounter delays or audit findings because they:

Reformat first and inform the BIR only after data is lost
Rely entirely on the POS vendor without checking the PTU
Install a newer, unaccredited software version
Restore an outdated invoice template
Restart the invoice sequence at number one
Fail to preserve the final Z-Reading
Lose the original PTU or BIR decal
Move the terminal to another branch without cancellation
Replace the motherboard or entire computer while treating it as the same registered machine
Fail to submit the three-day reset notification
Keep only printed summaries and discard the electronic journal
Use an unregistered backup device during downtime
Allow prior sales records to become inaccessible after migration
Use a training, no-sale, or hidden mode to avoid recording real transactions

The best protection is a compliance file containing every BIR letter, stamped receiving copy, vendor report, backup certification, final and initial reading, screenshot, sample invoice, PTU, accreditation document, and cancellation or approval certificate.

Possible Penalties and Audit Consequences

Unauthorized major repairs or modifications can expose the taxpayer to revocation of the PTU. Tampering, sales suppression, deletion of audit records, or alteration of recorded transactions can lead to more serious tax assessments and enforcement action. (Bir Cdn)

Failure to submit the prescribed reset notification may result in the ₱1,000-per-notification penalty, subject to the stated ₱25,000 annual aggregate limit.

Issuing an Official Receipt instead of the required Invoice as the primary sales document may be treated as failure to issue the required invoice. Section 264(a) of the Tax Code provides a fine ranging from ₱1,000 to ₱50,000 and imprisonment of two to four years upon conviction for covered invoicing violations. Actual liability depends on the facts and the applicable administrative or judicial proceedings. (Bir Cdn)

Missing POS data can also make it harder to disprove a BIR assessment. The BIR may compare Z-Readings, backend reports, electronic journals, VAT returns, income-tax returns, inventory records, bank deposits, card settlements, online-platform records, and third-party information.

Frequently Asked Questions

Do I always need a new PTU after reformatting a POS computer?

No. A new PTU is not automatically required merely because the operating system was reinstalled. The critical questions are whether the same registered hardware and accredited software remain in use, whether the version changed, and whether historical data, counters, and invoice sequences were preserved.

Can I reset my POS back to zero?

You should not manually zero out an active POS to make it appear unused. A legitimate system reset must remain visible in the audit trail and reset counter. The RDO must be notified within three days after the reset, with the required Z-Reading or End-of-Day report.

Can I use the POS immediately after the technician finishes?

Use should resume only after confirming that the restored system remains covered by the existing PTU or after obtaining any required new approval. At minimum, validate the taxpayer details, MIN, software version, counters, invoice sequence, historical data, and current invoice format.

Does the three-day reset letter have to be notarized?

RMO No. 24-2023 requires a letter notification and the printed Z-Reading or End-of-Day report but does not expressly state that the basic reset letter must be notarized. An RDO may request a sworn statement when additional facts must be established, particularly where data was lost or cancellation is involved.

Can the POS vendor submit the application or notification for me?

The supplier or provider normally files a CRM or POS PTU application through eAccReg on behalf of the taxpayer. For physical submissions, an authorized representative must carry the appropriate SPA, board resolution, written resolution, or secretary’s certificate and identification documents.

Can I issue manual invoices while the POS is being repaired?

Yes, provided the invoices are duly registered and compliant with current invoicing requirements. Maintain a clear downtime log and ensure those sales are included in the books and tax returns without being duplicated when the POS returns online.

Can I move the same POS to a temporary kiosk or another branch?

Not under the existing branch permit without completing the required BIR process. Transfer to another branch is a stated ground for cancellation of the old PTU and registration for the new location.

Do BIR POS permits expire every five years?

No. RR No. 6-2022 removed the five-year validity period. A PTU remains valid unless revoked. RMC No. 72-2025 further confirms that expiry of the supplier’s accreditation certificate does not, by itself, cancel the taxpayer’s existing PTU. (Bir Cdn)

What should I do if the POS was already reformatted and the records were lost?

Stop relying on the affected system until its integrity is assessed. Immediately prepare a written incident report for the RDO explaining what happened, when it happened, who performed the work, which records were lost, and what recovery efforts were made.

Reconstruct the data from all available sources, including:

Backups
Accounting records
Manual invoices
Bank deposits
Credit-card and e-wallet settlements
Online-platform reports
Inventory records
Customer ledgers
VAT and income-tax filings
Vendor or server logs

Attach the technician’s report, available pre-reset and post-reset readings, and proof of the attempted recovery. Missing reports should never be fabricated or backdated.

Key Takeaways

Reformatting a BIR-registered POS is a tax-compliance event when it affects sales data, counters, invoice sequences, hardware, or software.
Preserve the final Z-Reading, backend report, electronic journal, last invoice, counters, PTU details, and a tested database backup before any work.
Notify the RDO before a potentially major repair, upgrade, integration, or modification.
When a reset occurs, submit the required letter and Z-Reading or End-of-Day report within three days.
Major software, database, functionality, or bundled-hardware changes may require reaccreditation and a new PTU.
A POS transferred to another branch, taxpayer, franchisee, or owner normally requires cancellation and new registration.
A restored system must issue a compliant Invoice and preserve the existing serial-number and audit trail.
Existing POS permits do not expire merely because five years have passed or the supplier’s accreditation certificate has expired.
