For freelancers and business owners in the Philippines, proper bookkeeping is crucial for tax compliance. One essential requirement is the registration of Books of Accounts with the Bureau of Internal Revenue (BIR). Missing this step can lead to penalties, so knowing the registration deadline is important.
When Should You Register Your Books of Accounts?
According to the BIR Certificate of Registration (Form 2303), new business registrants must apply for registration of manual Books of Accounts (B/As) before the deadline for filing their initial quarterly or annual income tax return, whichever comes first. This means that as soon as you receive your BIR Certificate of Registration, you should prioritize this process.
Additionally, if you are registering a new set of manual books, you must complete the registration before using them to ensure compliance.

- Ensures compliance with the BIR tax requirements
- Helps in proper tracking of income and expenses
- Avoids penalties and legal issues
- Serves as a valid record in case of audits
