Keeping your books of accounts compliant with the Bureau of Internal Revenue (BIR) is not just a formality, it is a legal requirement that protects your business from penalties and unnecessary audits.

To address ongoing concerns and technical issues related to the Online Registration and Update System (ORUS), the BIR issuedRevenue Memorandum Circular (RMC) No. 4-2026on January 15, 2026. This circular clarifies themandatory online registration of books of accounts through ORUSand announcesextended registration deadlinesfor affected taxpayers RMC No. 4-2026.

Here is what every business owner and taxpayer needs to know.

What Is ORUS and Why Does It Matter?

TheOnline Registration and Update System (ORUS)is the BIR’s official online platform for registering books of accounts and updating taxpayer records. Since its nationwide implementation in 2023, ORUS has become thedefault and mandatory channelfor registering:

• Permanently Bound Loose-Leaf Books of Accounts
• Computerized Books of Accounts

Manual registration is no longer the norm and is now allowed only in exceptional cases.

Mandatory Online Registration Through ORUS

Under RMC No. 4-2026, the BIR reiterated thatall registrations of permanently bound loose-leaf books and computerized books of accounts must be completed online through ORUSwithin the prescribed deadlines.

Once registration is successful:

• AQR Code stampwill be generated by ORUS
• Forbound loose-leaf books, the QR Code must be affixed on thefirst page of the book
• Forcomputerized books, the QR Code must beprinted and kept for records

This QR Code serves as proof that your books are properly registered and verifiable online by the BIR.

When Is Manual Registration Allowed?

Manual registration is now consideredan exception, not the rule.

Taxpayers may only register manually at their Revenue District Office (RDO) if:

1. There is anofficial BIR advisoryconfirming ORUS system unavailability, or
2. The taxpayer can present ascreenshot of the ORUS error messageencountered during online registration

Without these conditions, manual registration requests may be denied.

Records Not Covered by ORUS

It is important to note thatnot all accounting records are covered by ORUS at this time.

The registration of the following must still be donemanually at the RDO:

• Loose-leaf invoices
• Official receipts
• Other accounting records not yet available for online registration

Extended Registration Deadlines Due to ORUS Issues

Due to intermittent log-in and system connectivity problems, the BIR granted deadline extensions under RMC No. 4-2026:

Taxpayers are strongly advised to complete registration within the extended periods to avoid penalties.

Why Compliance Is Important

• Penalties under existing revenue laws
• Issues during BIR audits or examinations
• Disallowance of books as valid accounting records

The BIR has emphasizedstrict compliance, even with the granted extensions.
