BIR Books of Accounts: Types, Registration and Recordkeeping Basics

BIR books of accounts are part of a business’s accounting records. They help document transactions and support the preparation and verification of financial and tax information. The exact books and procedures that apply depend on the taxpayer’s registration, activities and current Bureau of Internal Revenue rules.

This guide provides general information only. BIR regulations and procedures can change. Confirm your obligations with the BIR or a qualified Philippine tax professional before registering or changing your books.

What are books of accounts?

Books of accounts organize a taxpayer’s business transactions. Depending on the applicable requirements and accounting method, records may include journals, ledgers and subsidiary records that support sales, purchases, cash, expenses, receivables and payables.

The purpose is to maintain a consistent record that can be traced to source documents such as invoices, receipts, statements and other supporting evidence. A spreadsheet or accounting application may help organize information, but using software does not by itself establish that a taxpayer has met every BIR requirement.

Manual, loose-leaf and computerized records

Taxpayers may encounter different recordkeeping formats and procedures, including manual books, loose-leaf arrangements and computerized accounting records. The applicable process depends on current rules and the taxpayer’s circumstances.

Do not assume that one format is automatically available to every business. Before changing formats, determine what registration, notification, approval or other procedure is currently required. Keep evidence of the applicable registration or submission and follow the instructions relevant to your taxpayer type.

What should a business do?

1. Confirm its taxpayer details

Review the business registration, tax types, accounting period and other relevant taxpayer information. If the business has changed its activities or registration details, ask whether those changes affect its recordkeeping obligations.

2. Identify the required books

Ask a qualified accountant to identify the books and supporting records applicable to the business. Do not copy another company’s list without checking whether its taxpayer classification and transactions are comparable.

3. Verify current registration procedures

Use the BIR’s official website and current issuances to verify the process, documentary requirements and applicable deadlines. Procedures can change, and older blog posts or third-party checklists may no longer be accurate.

4. Keep records complete and retrievable

Record transactions consistently and retain supporting documents. Use clear descriptions, dates and references. Reconcile relevant balances regularly and make corrections through a documented process rather than silently overwriting prior records.

5. Protect and back up records

Limit access to authorized staff. Keep secure backups and test whether records can be restored. Make sure supporting documents can be located when the accountant or authorized reviewer needs them.

Questions to ask your accountant

• Which books apply to this taxpayer and its current registration?
• Which format and registration process are currently permitted?
• What source documents should support each type of transaction?
• How long should each record be retained?
• What is the process for correcting an error?
• Does a proposed accounting system support the workflow we actually need?

Official information and professional review

Start with the Bureau of Internal Revenue for current rules, issuances and taxpayer guidance. Confirm the date and scope of any circular or revenue regulation you rely on. For a business-specific answer, consult a Philippine CPA or tax adviser who can review your registration and transactions.

How accounting software relates to books of accounts

Accounting software can help organize transaction data and produce reports, but the taxpayer remains responsible for using an appropriate process and meeting applicable requirements. Ask a software provider to explain exactly what the product does, what it does not do and what supporting procedures remain the business’s responsibility.

GodoERP should not be described as BIR-accredited or BIR-approved unless there is current documentary evidence for that exact product and legal entity. A certificate associated with a different product does not establish GodoERP’s status.

Good recordkeeping starts with knowing which rules apply, keeping source documents and maintaining books that can be reviewed and explained.
