The Bureau of Internal Revenue (BIR) has introduced a new opportunity for qualified micro taxpayers to settle unresolved tax obligations through Revenue Regulations No. 4-2026. The initiative is designed to help eligible taxpayers clear outstanding tax issues, update their records, and return to full tax compliance without carrying the burden of accumulated penalties.
For many small business owners, freelancers, and self-employed individuals, missed tax filings or unpaid obligations often grow into larger problems over time. This new program gives qualified taxpayers a chance to address these concerns through a simplified process.
Revenue Regulations No. 4-2026 establishes the guidelines for a one-time abatement of taxes and penalties for qualified micro taxpayers with delinquent accounts, pending tax assessments, or open stop-filer cases. The program aims to encourage voluntary compliance while helping taxpayers move forward with a clean tax record.
Applications for the program will be accepted until December 31, 2026.
The program is intended for micro taxpayers who meet specific eligibility requirements, including:
Qualified applicants must submit their application to the Revenue District Office (RDO) that has jurisdiction over their registration.
Taxpayers who qualify must file an application with their respective RDO and pay a one-time abatement fee of ₱5,000 for every approved application.
Once all requirements have been satisfied, the BIR will issue a Certificate of Availment, confirming that the taxpayer has successfully availed of the program and that the covered tax case has been officially closed.
Small businesses often face financial and administrative challenges that make tax compliance difficult, especially during periods of low business activity or business closure without proper deregistration.
The One-Time Tax Abatement Program provides an opportunity to:
For many entrepreneurs, this initiative can make it easier to focus on growing their business instead of worrying about unresolved tax obligations.
