BIR Registration Requirements for Small Businesses in the Philippines
(Comprehensive legal overview – updated to 2025)
Important note: This article is for general information only and does not constitute legal or tax advice. Bureau of Internal Revenue (BIR) rules change frequently; always confirm the latest issuances or consult a qualified Philippine tax professional before acting.
1. Statutory and Regulatory Foundations
| Instrument | Key provisions for start-ups & MSMEs |
|---|---|
| National Internal Revenue Code (NIRC), as amended by the TRAIN Law (RA 10963, 2017) and CREATE Law (RA 11534, 2021) | Defines taxpayer classes, VAT threshold (₱3 million), annual registration fee, penalties, 8 % income-tax option, and reduced corporate income tax for small corporations (20 %). |
| Revenue Regulations (RR) & Revenue Memorandum Circulars (RMC) | Flesh out documentary requirements, e-filing mandates, electronic invoicing/POS accreditation (RR 11-2018, RR 16-2023, RMC 5-2024, etc.). |
| MSME statutes (RA 6977 as amended by RA 9501) | Classify micro (≤₱3 M assets), small (₱3–₱20 M), medium (₱20–₱100 M). The BIR does not create a separate registration lane but other agencies (DTI, SEC, LGUs) use these sizes. |
| Barangay Micro Business Enterprises Act (BMBE, RA 9178) | Income-tax exemption for registered BMBEs but still requires BIR registration and compliance with invoicing and withholding rules. |
2. Before You See the BIR
Choose a legal form
Form Primary registry Typical use for MSMEs Sole proprietorship DTI - Business Name Freelancers, small retailers One-Person Corporation (OPC) SEC Limited-liability alternative for solo owners Partnership or ordinary stock corporation SEC Multi-owner ventures Cooperative CDA Social/sector-based enterprise Secure local permits
- Barangay Clearance
- Mayor’s/Business Permit (city/municipality)
Both are usually prerequisites for the BIR’s Certificate of Registration (COR).
Identify your BIR Revenue District Office (RDO)
Registration is always on-site (or via eREG if available) at the RDO that has jurisdiction over the principal place of business or the owner’s registered address.
3. Documentary Requirements Checklist
