For every business in the Philippines, tax compliance is more than just a legal obligation — it’s a vital part of sustainable growth and credibility. Whether you run a small enterprise or manage a growing company, staying on top of your monthly BIR (Bureau of Internal Revenue) remittances is crucial to avoid penalties, maintain good standing, and ensure smooth operations.
In this guide, we’ll walk you through how to handle monthly BIR remittances like a pro — from identifying the correct tax forms to filing and paying efficiently.
What Are Monthly BIR Tax Remittances?
Monthly BIR remittances refer to the regular submission and payment of taxes required by the Bureau of Internal Revenue. These include withholding taxes, value-added tax (VAT), and percentage taxes depending on your business type and registration.
Failing to file and remit taxes on time can lead to hefty fines, surcharges, and legal issues — making compliance a must for every business owner.

Here are the most common types of monthly tax filings required in the Philippines:
- Withholding Tax on Compensation (Form 1601-C)

- Deadline: On or before the 10th day of the following month.
- Example: Taxes withheld in January must be remitted by February 10.

- Deadline: The last day of the following month.
- Value-Added Tax (Form 2550M / 2550Q)

Step 1: Identify Applicable Taxes
Determine which taxes your business must withhold or pay monthly:
- Employee salary deductions

Step 4: File Your Tax Forms
You can submit BIR forms through:
- eBIRForms system (offline and online versions)
- Electronic Filing and Payment System (eFPS) for registered businesses
After filing, you’ll receive an email confirmation or a submission receipt — keep this as proof of compliance.
Step 5: Pay Your Taxes
Once filed, you can pay through any of the following:
- Authorized agent banks (AABs)
- GCash or Maya (for small business convenience)

Always double-check payment reference numbers and keep digital copies of receipts for audit purposes.

The BIR requires records to be kept for at least 10 years, especially during audits.
