In the Philippines, the importance of proper bookkeeping cannot be overstated—especially when the Bureau of Internal Revenue (BIR) comes into the picture. The National Internal Revenue Code (NIRC) of 1997, as amended, specifically Sections 232, 233, 234, and 235, outlines the legal backbone for the keeping of books of accounts and records. For businesses, professionals, and even non-profit organizations, compliance with these sections is not just a matter of good practice—it is the law. 

This blog aims to provide a clear understanding of what these sections require, their purpose, and how they affect taxpayers. Whether you're a sole proprietor, a corporation, or an accountant guiding your clients, this guide will help you align your bookkeeping practices with Philippine tax laws.

Section 232: Keeping of Books of Accounts

Section 232 mandates the keeping of books of accounts and other accounting records for all individuals or entities engaged in trade, business, or the practice of a profession. These records must reflect the taxpayer's true income and expenses.

Who is Required to Keep Books?

The section identifies the following:

1. Corporations, Companies, Partnerships, or Persons—All entities engaged in trade, business, or the practice of a profession must maintain and register books of accounts with the BIR.  
2. Large Taxpayers and VAT-registered Persons—Required to keep books of accounts and submit audited financial statements prepared by a CPA accredited with the BIR and the Board of Accountancy.
3. All Other Taxpayers—Regardless of income level, all registered taxpayers must keep books. The old rule requiring only those with quarterly gross sales/receipts over ₱150,000 to maintain simplified books has been replaced. Now, compliance depends on whether books are manual, loose-leaf, or computerized, and proper registration through ORUS.

What Books Must Be Kept?

Taxpayers must maintain:

• Journal and Ledger (or their equivalents, serving as primary record of transactions.)
• Subsidiary books (such as Cash Disbursement Book, Cash Receipt Book, Sales Book, Purchases Book, etc.)
• Invoices and Official Receipts (must be registered with the BIR and must be issued for every sale and service rendered.)
• Supporting documents (e.g., vouchers, contracts, and correspondence, and other evidence of transactions)

Format and Registration

- Books must be kept in the Philippines in manual, loose-leaf, or computerized format.  

- Manual Books are physically stamped at the RDO.  

- Loose-Leaf and Computerized Books must be registered online via ORUS, with a QR code serving as proof of registration.  

- All formats require BIR authorization or registration before use.  

Format and Language

Books and records must be kept in English or Filipino, and all amounts must be expressed in Philippine Peso.

Section 233: Subsidiary Books and Other Accounting Records

Section 233 allows taxpayers to keep subsidiary books and other accounting records as needed in their business operations.

Flexibility and Customization

While Section 232 mandates the minimum requirement, Section 233 provides flexibility. Businesses may maintain additional records such as:

• Accounts Payable and Accounts Receivable Ledgers
• Inventory Books
• Payroll Registers
• Bank Reconciliation Statements

This section is especially important for larger enterprises that require more granular tracking of financial information for management, audit, and tax purposes.

Modern Accounting Systems

Under this section, computerized accounting systems (CAS) and loose-leaf books are allowed provided they are registered with the BIR. It is crucial to obtain a Permit to Use (PTU) for CAS or submit the loose-leaf format for approval.

Section 234: Language and Manner of Keeping the Books of Accounts

This section governs the language and presentation of accounting records. While Section 232 requires the books to be in English or Filipino, Section 234 adds clarity to how this must be executed.

Acceptable Language

Books of accounts may be:

• Kept in a native dialect, English, or Filipino
• But if in a foreign language, a true and complete translation must be made available to the BIR upon demand.

Electronic Books

Section 234 now explicitly recognizes the use of electronic books of accounts through accounting software or ERP systems, provided that:  

- Compliance with BIR guidelines is ensured (registration via ORUS, QR code validation, and approval of Computerized Accounting Systems when required).  

- Proper documentation, translations, and back-ups are maintained.  

- Electronic records must be readily accessible and capable of being produced in printed form upon BIR request.  

Non-compliance

Failure to comply with the prescribed language or manner of keeping books can result in:  

- Disallowance of expenses during audits.  

- Rejection of books as valid evidence.  

- Administrative penalties under the NIRC, including fines up to ₱50,000 per violation.

Section 235: Examination of Books and Records

One of the most critical provisions is Section 235, which grants the BIR the authority to examine the taxpayer’s books and records.

BIR's Right to Audit

The BIR may examine or inspect books and records once every taxable year, except in certain cases such as:

• Fraud
• Irregularity or mistake
• Taxpayer's request for reinvestigation
• Verification of compliance with withholding tax laws
• Capital gains tax audits
• Tax refund or tax credit claims

Retention Period

Books of accounts must be kept for ten (10) years, and the last five years must be readily accessible. This is critical during audits or when legal disputes arise.

- Electronic Records  

  For taxpayers using electronic books or computerized accounting systems, electronic backups must be maintained for the same retention period, ensuring accessibility during audits.  

- Audit and Legal Use  

  Retention is critical during BIR audits, tax investigations, or legal disputes, as failure to produce records can lead to disallowance of expenses, rejection of books, and penalties under the NIRC.  

Time and Manner of Examination

The BIR must conduct the examination during office hours and at the taxpayer's place of business, unless otherwise agreed upon. They must also issue a Letter of Authority (LOA)—a prerequisite for any examination to be legally valid.

The Cost of Non-Compliance

Failure to keep proper books of accounts can result in:

Worse, non-compliance may lead the BIR to impose compromise penalties or closure orders under the Oplan Kandado Program.

Accountability Is Good Business

In the realm of taxation, good recordkeeping is not optional—it is a requirement backed by law. The NIRC’s Sections 232 to 235 emphasize the government’s desire for transparency, accuracy, and accountability. These are not merely administrative burdens—they protect both the taxpayer and the State.

So, whether you’re managing a small online business, a growing corporation, or a professional practice, make it a habit to write it right. Doing so will save you from unnecessary stress, cost, and conflict with the tax authorities.

When your books are in order, your business is in order—and that is the foundation of sustainable, ethical, and compliant entrepreneurship in the Philippines.
