Extension
The Philippines has granted an extension for all tax deadlines due within October 2025, allowing taxpayers to file and pay their taxes until October 31, 2025, due to the recent earthquake in Cebu. This extension is intended to assist affected taxpayers in complying with their obligations without additional hardship.
“This extension relieves our taxpayers of additional expenses brought on by the disaster while giving them enough time to fulfill their tax obligations.”- BIR Commissioner Romeo D. Lumagui, Jr.
Compliance
Following the tax calendar is indeed a crucial aspect of responsible financial management. Timely compliance with tax deadlines helps taxpayers avoid penalties, interest charges, or other consequences such as the suspension of government services or business permits. The BIR strongly advises all taxpayers to carefully review their tax forms and declarations before submission to ensure all information is accurate and complete.
Accurate filing minimizes the risk of audits or disputes with the tax authorities, streamlines processing, and helps maintain good standing with the BIR. Being proactive in meeting deadlines and verifying documents strengthens overall financial discipline and legal compliance for individuals and businesses alike.
This approach also fosters trust and transparency with regulators, safeguarding long-term operational stability and access to government services. Employers must also remit Pag-IBIG contributions according to their alphabetic schedule and ensure all forms are accurate before submission to avoid penalties.
Adjustments
When a tax filing deadline in October 2025 falls on a holiday or weekend, the due date is automatically extended to the next working day. This adjustment ensures taxpayers have sufficient time to comply without penalties.
For October 2025, eFPS filers have staggered deadlines from October 11 to 14, based on their assigned alphabetical groups, while non-eFPS filers must file and pay by October 10. These measures help manage the filing flow and prevent congestion, supporting better compliance.
